Freezing rain risk for parts of southern MB tonight..

GEM outlook for midnight tonight.
Red highlights areas of potential
freezing rain

A weather system over southern Saskatchewan will be pushing a warm front across southern Manitoba today into tonight, ushering a milder airmass from the south. Temperatures will be climbing towards the freezing mark overnight, especially closer to the US border. The milder weather however will also bring a threat of freezing rain or ice pellets tonight as the weather system track across southern MB. An area of freezing rain is expected to develop over southeast SK late today, and spread into SW Manitoba this evening.  A freezing rain warning has been issued for these areas. This area of freezing rain may push into Winnipeg and the RRV overnight, however at this point, it appears the greatest risk is over SW Manitoba into parts of the interlake. This system will push east of southern MB Saturday morning, with drier and briefly cooler conditions in its wake.  

UPDATE DEC 1st: TransCanada Highway is closed from Winnipeg to SK border this morning due to severe icing conditions. Travel not advised on many other roads in southern Manitoba, especially north and west of Winnipeg due to ice covered conditions from freezing rain overnight. For latest road and highway conditions, see Manitoba highways website.

Note also that radar images from the Weatheroffice website are now on SNOW rate and will overdo precipitation intensities during rainfall events. Consult Brad's radar viewer from A Weather Moment for radar images showing more accurate RAIN rate intensities during rain or freezing rain events in the winter (select 1.5 km CAPPI for RAIN rate).

Snow spreading into Winnipeg from the west this afternoon.. 2-5 cm possible through this evening.

An area of snow over southern Saskatchewan is spreading into western Manitoba this morning, with visibilities starting to drop in the Dauphin and Brandon regions and towards the SK border.  Snow will continue to spread eastward today reaching Winnipeg by mid to late afternoon, in time for the evening rush hour.  Snow will continue to increase through the evening with about 2-5 cm likely in Winnipeg by midnight, with higher amounts of 5-10 cm possible along the Yellowhead corridor into the Riding Mountains.  Snow will gradually taper off overnight as this system pulls off to the east. Friday will be mainly cloudy but turning milder as southerly winds start drawing up warmer air from the south.  Another weak system will be crossing southern Manitoba Friday night into Saturday with more snow likely through the interlake regions, with mixed precipitation including the risk of freezing rain over Winnipeg and the RRV.  A stronger storm system will likely impact southern Manitoba Sunday night into Monday, with rain or freezing rain over the RRV changing to snow along with strong northwest winds and falling temperatures.

Follow snow on radar. Keep in mind that radar images from the Weatheroffice website are still on RAIN rate and will underplay snow intensities (radar will be changing to SNOW rate on Mon Dec 3rd). Consult Brad's radar viewer from A Weather Moment for radar images showing more accurate SNOW rate intensities.  For latest road and highway conditions, see Manitoba highways website.

Cold and dry next couple of days.. then snow chances and temperatures increase late week into weekend

Cold high pressure building over the Prairies today will bring cold but snowfree conditions today into Thursday over southern Manitoba. Temperatures will be several degrees below normal with highs around minus 10, and lows tonight near -20C, although Wednesday will likely moderate briefly to around -7c.  By Thursday evening, a wave of snow will be pushing across southern Manitoba ahead of a warm front that will be moving in from the west. This front will usher in milder air for Friday into the weekend, with temperatures climbing towards the freezing mark. Additional snow is possible Friday night into Saturday as another wave of precipitation pushes across southern Manitoba.   Long range guidance is hinting at a possible stronger storm system affecting southern  MB Monday bringing in a flow of milder air across the RRV with even some rain possible.    

A little more snow Saturday.. gusty south winds will give occasional blowing and drifting snow..

GEM prog valid noon Sat Nov 24th
showing band of snow moving
across southern MB

A low pressure system over southern Alberta will be tracking into southern Manitoba Saturday bringing a band of snow ahead of it. This band of snow is expected to spread into western MB overnight reaching the Interlake and RRV areas Saturday morning. The snow will push east towards the Ontario border by late afternoon with about 2-5 cm possible as the area of snow moves through. The heaviest amounts are expected mainly north and east of Winnipeg. Note that the snow will also be accompanied by brisk southerly winds gusting to 50 or 60 km/h in Winnipeg and the RRV, which will give occasional blowing and drifting snow and locally poor visibilities at times. (eastbound lanes of west-east highways will be most prone to drifting snow Saturday) Caution is advised if travelling Saturday, particularly in areas near and outside the Winnipeg perimeter.   

NOTE: Woodlands radar is currently not updating. Keep in mind that radar images from the Weatheroffice website are still on RAIN  rate and will underplay snow intensities. Consult Brads's radar viewer from A Weather Moment for radar showing more accurate SNOW rate intensities.  For latest road and highway conditions, see Manitoba highways website.

Blustery and colder today with snow moving in..

The pleasant stretch of above normal temperatures and quiet weather will be coming to end today thanks to a cold front that pushed through southern Manitoba overnight. Gusty north winds to 50 or 60 km/h behind the front will usher in much colder air from the northern Prairies, with temperatures falling through the day towards the -10C mark by evening. The gusty northerly winds will be make it feel even colder with wind chills falling to the -20 range. In addition, periods of snow will be spreading across Winnipeg and the RRV this morning,  with about 5 cm possible by the drive home.  This will result in deteriorating road conditions today, with occasional reduced visibilities in snow and blowing snow. Road conditions are already slippery this morning from some early morning freezing drizzle that left a coating of ice on untreated surfaces.. and  a layer of wind blown snow will continue to make for slippery conditions through the day into the evening. Caution on the roads today.. winter driving skills will be required once again.

Follow snow on radar today. Keep in mind that radar images from the Weatheroffice website are still on RAIN  rate and will underplay snow intensities. Consult Brads's radar viewer from A Weather Moment for radar showing more accurate SNOW rate intensities.  For latest road and highway conditions, see Manitoba highways website.

Dry and mild start to the week.. turning colder with some snow likely by Thursday

Generally pleasant and dry weather is expected over southern Manitoba over the next few days as a series of low pressure systems passes to the north of the region.  This will bring a flow of above normal temperatures over the south with daytime highs generally above freezing today through Wednesday. Warmest temperatures will be over far southeast MB which has minimal snow cover, with highs of +5 to +8C possible over the next few days. By Wednesday, scattered showers are possible ahead of  a low pressure system that will be developing over southern SK. This system will drag a cold front through southern Manitoba by Thursday with some snow possible as colder air works in behind it. This doesn't look like a major system at this point, with snowfall amounts of 2-5 cm being forecast by the long range models along with gusty north winds. Still, it will likely be enough to bring wintery driving conditions over southern MB once again, after a period of relatively benign weather. Until then, enjoy the nice weather for the next few days!   

Cold start to the week with a milder finish. No more snow for awhile..

It will be a cold start to the week after a weekend storm system brought widespread snow across southern Manitoba. Temperatures today will remain around the -5C mark with brisk NW winds making it feel more like -15 with the windchill.  For tonight, clearing skies and diminishing winds over a fresh snowpack will allow temperatures to drop to the coldest of the season so far, with -20C temperatures likely by Tuesday morning. Below normal temperatures will persist through midweek before a moderating trend towards late week with temperatures rising towards the melting point. In fact, long range models are indicating warmer than normal weather over the weekend into early next week with above freezing temperatures expected. In addition, no new snow is expected the rest of this week which will help in snow clearing operations from the weekend storm. All in all, a nice week ahead after a winter-like start! 

Winter storm delivers winter wallop to southern Manitoba

10 pm Nov 10th when heavy snow
was giving 5 cm/hr snowfall rates

Winter arrived with a vengeance Saturday as a well advertised winter storm brought widespread snow across most of southern Manitoba Saturday into Saturday night.  The "Colorado low" storm system which tracked across northern Minnesota last night, brought two waves of snow.. one that began in the early morning hours Saturday and pushed into the Interlake areas, and another heavier burst of snow Saturday night that brought very heavy snowfall rates of up to 5 cm/hr at times across the Red River valley including Winnipeg. When the snowfall finally tapered off Sunday morning, it left some impressive snowfall totals over most of southern Manitoba, transforming what was a bare snowfree landscape Friday into a winter wonderland within 36 hours.

was typical across much of
southern MB Sunday morning

Winnipeg's snowfall of 22 cm was the city's greatest 24 hr snowfall since Dec 30-31 2006 when 32 cm fell. Heaviest snowfall with this storm was in a wide swath from the Riding and Duck Mountains through the northern Interlake, as well as a narrower band from the western RRV through Portage la Prairie into the central interlake thanks to some slow moving heavy snowbands that set up Saturday evening.  Neighbouring eastern Saskatchewan was also hard hit with 30-45 cm reported from Regina to Yorkton. Snowfall was much less south and east of Winnipeg especially towards the Ontario border where precipitation was mixed with freezing rain Saturday.

Winter Storm Update

Snow has spread over southern MB this morning with the heaviest snow occurring through western MB and the interlake areas. As of  9 am, about 15 cm of snow has fallen through the Roblin/Dauphin areas, with 8 cm in Brandon, 5 cm in Portage and about 2-3 cm in Winnipeg. Snowfall drops off to a dusting south and east of Winnipeg where precipitation is mixing with freezing drizzle or ice pellets. Winnipeg will be on the edge of  heavier snow to the west and north today, and more intermittent light snow to our south and east. As such, the weather in Winnipeg today will vary between periods of light snow, and heavier bursts from time to time. In general, about 5-10 cm of snow is expected in Winnipeg today, with higher amounts of 10-20 cm to our north and west, and lighter amounts of 2-5 cm to our south and east.  For tonight the storm system will be tracking into northern Minnesota and NW Ontario, bringing another wave of heavier precipitation over southern MB. This could bring another 10-15 cm of snow to Winnipeg and the RRV overnight into Sunday morning before the snowfall tapers off. So we'll be dealing with this storm for the next 24-36 hours yet.. Overall, Winnipeg could see about 15-25 cm of snow from this system, with the heaviest snowfall over western MB into the interlake areas where 30-40 cm is possible by Sunday evening.

Major winter storm takes aim at southern Manitoba..

The well advertised winter storm that we've been following for a week now is getting closer, and snow from the system will be spreading into southern Manitoba this afternoon into tonight, with heavy snow expected over the weekend. A WINTER STORM WARNING is in effect for much of southern Manitoba, including Winnipeg and the RRV, with general snowfall accumulations of 20-30 cm expected across much of the area by Sunday morning, with up to 40 cm possible over portions of southwestern MB. Further east, the storm will likely bring a band of freezing rain or ice pellets towards the Ontario border overnight and Saturday before changing to all snow Saturday night into Sunday.  In Winnipeg, light snow is expected to develop this evening, becoming steadier and heavier after midnight with 5 cm possible by Saturday morning. Snow will continue all day Saturday with another 10-20 cm likely by evening along with northeast winds gusting to 50 km/h at times. Additional snow is expected Saturday night into Sunday morning before the storm gradually moves out with storm totals of 20-30 cm possible across the Red River valley, including Winnipeg.

Regardless of the total amount of snow that falls, residents should be prepared for a prolonged period of snowy weather over southern MB beginning tonight, lasting through Saturday into Sunday morning, and gradually tapering off later Sunday. Road conditions will deteriorate as the storm progresses, especially Saturday and Saturday night when the bulk of the snow is expected across southern MB.  Be prepared for much slower travel times and possible road closures. (In fact, I wouldn't be surprised to see the TransCanada closing tomorrow from Winnipeg to the Saskatchewan border) Northerly winds of 30 to 50 km/h will accompany the storm with reduced visibility at times in snow and blowing snow. Improving conditions are expected later Sunday as the storm pulls off. Note that this storm will also be affecting neighbouring southern Saskatchewan, North Dakota, NW Minnesota, and NW Ontario so keep that in mind if you have travel plans to those areas this weekend.   For MB highway conditions and any road closures, visit Manitoba Highways website. 

Follow the storm on radar!  Follow the storm on radar using Radar Viewer from A Weather Moment, which is displaying radar echoes in SNOW mode.  Note that radar imagery on the Weatheroffice website is still on RAIN rates, and will significantly underplay snow intensities. Radar imagery on Weatheroffice is fixed on rain rates nationally until Dec 1st when it switches over to snow rates.

Snowy Saturday on tap.. but how snowy?

Rob's Obs Snow Poll average:  17.2 cm (based on 101 entries)

This is what many roads in southern
Manitoba may look like Saturday

It's looking increasingly likely that a significant snowfall will be impacting southern Manitoba by Saturday, with the season's first widepsread snowfall of the season expected for the RRV and much of southern MB.  Environment Canada has issued a SNOWFALL WARNING for much of southern MB, including Winnipeg, for the potential of 15 to 25 cm of snow Friday into Sunday. Although there remains some uncertainty about how much snow will fall in any one location (including Winnipeg), there are a few things that are looking more likely about this impending snowfall event..

Expected storm position
valid 6 am Sunday Nov 11th
(HPC - NOAA)

- Storm track: Low will be tracking towards Duluth (see image left). That increases odds of heavier snow over SE MB and less snow towards the SK border 
- Precip Phase: Will be an all snow event. With the above storm track, likelihood of mixed precipitation (freezing rain/ice pellets) is reduced over most of southern MB 
- Timing: Snow will be spreading in from the southwest late Friday, persisting through Saturday and Saturday night, then gradually pulling off Sunday. Snow expected to develop in Winnipeg Friday night (midnight or pre-dawn hours Saturday)

OK, but what about what everyone wants to know: how much snow will fall in Winnipeg?  Models still have been flip-flopping on that issue, but the consensus is growing that Winnipeg will see around 15 cm of snow in total from early Saturday into Sunday morning.  Model estimates for Winnipeg range from a minimum of 10 cm  to a high of 30 cm, but overall, they seem to converging around that 15 cm mark.  It's likely however that some areas of southern MB will see more than that, perhaps 20-30 cm, including parts of the RRV and SE Manitoba (and possibly even Winnipeg if a heavier snowband hits the city)

Regardless of the total amount that falls, residents should be prepared for a period of snowy weather over southern MB beginning Friday night, lasting through Saturday, and easing off Sunday. Road conditions will deteriorate as the storm progresses, especially Saturday when the bulk of the snow is expected across southern MB.  Be prepared for much slower travel times and possible road closures.  Northerly winds of 30 to 50 km/h will accompany the storm with reduced visibility at times in snow and blowing snow. Improving conditions are expected Sunday as the storm pulls off. Note that this storm will also be affecting neighbouring North Dakota, NW Minnesota, and NW Ontario so keep that in mind if you have travel plans to those areas this weekend.

Winter storm threat increasing for southern MB this weekend.. snowfall amounts still uncertain

Long range computer models are coming into agreement that a significant winter storm will likely be impacting southern MB by Saturday.  Models show a storm system developing over the central US Rockies later this week and tracking into Minnesota by Saturday, bringing a swath of snow across the northern Plains states and southern Prairies. Although models agree on this general premise, there is still some uncertainty about exactly where the storm will track, which will have major implications on where the heaviest snow falls over southern MB. Currently, there are 3 main scenarios that are possible. With each scenario, I give a likelihood of that outcome occurring (purely subjective based on my own analysis and interpretation)

Scenario 1 -  Weaker low tracking near Duluth 

Southern MB impacts:  Colder with less snow over western MB and RRV, more snow over SE MB     
Winnipeg snowfall:  5-15 cm (less snow north and west, more snow south and east)
Likelihood:  25% (Updated Nov 9th) 25%




 

Scenario 2 - Stronger low tracking near International Falls 

Southern MB impacts:  Heaviest snow over RRV and interlake, less snow over SE MB     
Winnipeg snowfall: 15-25 cm (less snow west and east)
Likelihood:  50% (Updated Nov 9th) 55%






Scenario 3 - Strong low tracking near Lake of the Woods

Southern MB impacts:  Heaviest snow over western MB and interlake, less snow over RRV/SE MB with freezing rain or ice pellets possible      
Winnipeg snowfall: 10-15 cm (more snow north and west, less snow south and east)
Likelihood:  25%  (Updated Nov 9th) 20%



 

In all cases, the bulk of the snow is expected to fall Saturday with snowfall tapering off Sunday. Winds will depend on the strength and track of the low, but generally the strongest winds will accompany the area of heaviest snow, which will lead to snow and blowing snow issues.

I will continue to monitor the situation and have updates as the week progresses. During that time, updated model solutions will hopefully be converging towards a more consistent forecast that I can relay with more confidence. In the meantime, you may want to start making sure you have the winter gear handy for the end of the week, and your vehicle is prepared for winter driving conditions (including snow tires)

A little rain Monday evening then a quiet week. Winter storm threatens southern MB by weekend..

Weather map for 6 pm Monday
showing band of rain and wet
snow pushing across southern MB

A warm front over northern Alberta will push into southern MB Monday bringing a band of precipitation ahead of it. The bulk of the precipitation should fall as rainshowers through the Interlake Monday afternoon into the RRV by evening, with some wet snow mainly north and east of Lake Winnipeg. Further west, the warm front will likely result in some patchy dense fog developing overnight into Monday morning across SW Manitoba especially towards the SK border.

Nov 11th showing strong
system affecting southern MB 

After Monday, things look generally quiet over southern MB the rest of the week with generally fair weather and seasonable temperatures. By next weekend however, long range models are hinting at a potentially significant winter storm affecting southern MB Saturday into Sunday, with the possibility of heavy snow and strong winds. The storm is still a ways off and there are track and intensity differences from the various models that will have a major impact on forecasting who gets snow and how much. So at this point, all we can say is that the POTENTIAL for a significant snowfall of 10 cm or more exists for much of southern MB next weekend, including Winnipeg. I'll be posting blog updates on this developing situation as the week progresses.

Some snow moving into southern Manitoba overnight into Friday

Weather map for midday Friday
showing area of snow pushing
into the RRV from the west

A weak weather system over southern SK is forecast to spread an area of snow over southern MB overnight into Friday, bringing some accumulating snow to much of the area.  Snow is expected to move into SW Manitoba overnight, gradually spreading into the Red River valley including Winnipeg by Friday afternoon (see top image). The snow is expected to continue through the evening rush hour into Friday night before tapering off early Saturday. Snowfall amounts are expected to range from 5-10 cm over SW Manitoba to about 2-5 cm in the Red River valley including Winnipeg (see lower image), with the highest amounts mainly south and west of Winnipeg. Little snow is forecast north and east of Winnipeg as the system slides to the southwest of the Red River valley and weakens.

valid 7 am Fri - 7 am Sat

Luckily, winds will be light accompanying the system with temperatures near the freezing mark so blowing or drifting snow should not be an issue. Still, this will likely be the first widespread accumulating snow the city has seen since early October, so be prepared for some winterlike driving conditions by late Friday, especially if you're headed west of the city.




11 am Nov 2 UPDATE: Snow has spread over southwest MB this morning with MB highways reporting snowcovered roads west and northwest of Brandon. See recent photo taken on Hwy 16 near Foxwarren..

5:30 pm UPDATE:  Snow over southwest MB has edged eastward to a Portage-Carman-Emerson line. Snow is occurring moderate to heavy at times along and west of this line, with visibilities down to 1 km at times.  Snow will slowly move east into the Red River valley this evening with light snow possible in Winnipeg, although bulk of snow will likely remain south and west of Winnipeg.
