Snowy weather set to return tonight..

After a couple of spring-like days over the Red River valley that saw the snowpack virtually disappear with temperatures in the +8-13C range, wintery weather is set to return by this evening as a weather system crosses southern Manitoba. Snow is expected to develop across the Red River valley by early this evening as the system gets organized, with a risk of some freezing rain or ice pellets at the onset. Snow will continue tonight into Saturday morning with accumulations of around 5 cm by the time it tapers off. As the system moves into NW Ontario Saturday, gusty northwest winds of 30 to 50 km/h will develop over southern MB with temperatures near the freezing mark. Clearing skies are expected for Sunday with above normal temperatures into early next week.

UPDATE: 8 am Nov 26th: 6.4 cm of snow at my place since last evening. 6 cm snow on ground. Snowfall total since Nov 1st: 22 cm. Normal Nov snowfall: 21 cm.

  7. ROb!!!
    According to the GFS this week looks to be a very windy one in general!!
    There seems to be many warm ups followed by cold blasts that will really whip up the winds.

  8. 6.4 cm of snow at my place as of 8 am.. snow is pretty much over. As Daniel mentioned, snow is wet and heavy as opposed to that light fluffy snow we had last week, so this stuff will be a little more effort to shovel. Sure looks pretty though, and temperatures are still nice and mild which makes it a great day to enjoy it.

  9. Sent a nice pic to your facebook page showing the winter scene from my balcony!

  10. Yeah.. a winter wonderland out there today. Reminds me of the snowfalls I used to enjoy in Southern Ontario.. nice wet packy snow with temperatures near the melting point.

  11. Rob!

    Since you work at the weather office, can you tell me when there is an obseravtions other than on the hour ( ex. 12:08) does EC request those special updates or is just random that someone goes out to check on the conditions.

    For example does EC like constant updates today so they can see when the foggy conditions are going to lift??

  12. daniel.. Weather observations are taken by weather observers (where there still are) under contract to Transport Canada to provide weather data for aviation purposes. They are required to take at least one observation every hour at the top of the hour, but will also issue supplementary observations at any time when weather conditions cross certain aviation thresholds (such as cloud ceiling heights, visibility thresholds, precipitation start or ending, thunder/lightning, etc) So extra observations are based on the weather and aviation requirements.

    More and more, weather observations are being taken by automated stations which have these aviation thresholds pre-programmed, and will automatically issue supplementary obs whenever those thresholds are crossed (which can sometimes be every few minutes in changeable weather!)

  13. Quite the wind event in southern Alberta today.. Claresholm, south of Calgary, reporting sustained winds of 102 km/h gusting 130 km/h with a peak gust of 145 km/h (78 knots) past hour! Travel not advised on highways due to winds, especially for high profile vehicles. Skyscraper windows being blown out in downtown Calgary where gusts are hitting over 90 km/h at the airport (even stronger at the top of high buildings).

    ReplyDelete
  14. WOW! That is impressive!
    We will be windy tomorrow, but nothing like that!!

    ReplyDelete
  15. Anyone have any thoughts on Wednesday's system???

    ReplyDelete
  16. Got to 6,1 C here today in south end. Amazing, very little snow left in the sun, still a good amount in shade... Winter's having a hard time settling in for good this year! =)

    ReplyDelete
  17. daniel..

    Looks like bulk of snow with Wednesday's clipper will be tracking mainly across southern SK into ND.. grazing southern MB. We may get a dusting here in Winnipeg with a couple of cm possible over SW MB and the southern RRV. Worst of it looks like it will occur over southern SK with 5-10 cm possible along with gusty north winds and blowing snow issues.

  19. Another warm and dry month in November. NWS Grand Forks 4.6 abv normal. Fargo currently tied for third for driest fall on record (records to 1881) with only 1.41 precip.

    Has someone who likes the cloudier and colder side of things...having a really hard time.

    System wed aftn-eve looks pretty wimpy - maybe a coating which will go away next 32F day. Cold air up north though I saw -30s near Yellowknife Tues am.

  20. HANG in there Dan GF!!!
    My crystal ball says that December will bring lots of blizzards and very cold temps to.......ahhhhh, who 'am I trying to fool (sigh)

  21. Hi Daniel...

    Well maybe January....

    ReplyDelete
  22. cold blast tomorrow, Warm up on Friday, cold blast for the weekend, warm up early next week, cold blast mid week, warm up......

  23. Anyone know what's happening on Sunday. EC has been predicting periods of snow for days but no amounts. TWN was calling for 5cm now calling for scattered flurries 1-3cm. Wunderground saying 50% chance of snow and Accuweather not calling for any snow just a sun/cloud day. Other than thunder showers everything is covered. Someone will get it right.

    ReplyDelete
  24. LOL @ Daryl.
    As it stands right now, 2cm of snow seems about right for Winnipeg on Sunday.

    ReplyDelete
  25. Question is, will we have a brown Christmas this year??? At this rate it is possible unless we get some big snow sometime soon.This little snow we have won't last forever!!

    ReplyDelete
  26. I remember sometime in the late 80's we had almost no snow up until Christmas Eve and then it snowed quite a bit through Christmas day. I can't remember the year but maybe 1988.

    ReplyDelete
  27. I remember that year but the snow was in the week before Christmas, not Christmas Eve. Sure felt cold without snow on the ground.

    ReplyDelete
  28. Very light and fluffy snow this morning.A quick dusting here. -24C tonight and windchill to boot. BRRRRR. ~!~

    ReplyDelete
  29. -24 C for an overnight low is cold considering our slim snowpack.

    ReplyDelete
  30. Take a look at ARVIAT's forecast in Northern Canada. Now that is a severe 3-4 day blizzard. Can anyone tell me if a blizzard of that caliber is even possible in Southern Manitoba How can they get so many blizzards throughtout the year, while one of their's would be a once in a lifetime event for Southern Manitoba???

    ReplyDelete
  31. The only time I can remember a multiday event (blizzard) was the April storm in 1996 that started off as rain went to snow and really cold temps. I think it occurred over three days but I don't think it was a 72 hour deal.

    ReplyDelete
  32. That's why all the emergency personale encourage people to prepare to last 72 hours with emergency supplies in extreme events like these which are meant to happen at some point or another.

  33. Will be interesting to see tonite if we can get a non-diurnal temperature trend and tap that mild westerly flow sweeping across the prairies. +5 C as far north as Swan RIver currently.

    ReplyDelete
  34. That wind was crazy today. Wind gusts to near 80 km/h. Special weather Statement issued for the warm up followed by the quick cool down.

    ReplyDelete
  35. Hi,

    I was wondering if there is a big storm brewing for mid next week. AccuWeather is calling for snow next Thursday and Friday. One of my colleagues who has the AccuWeather Premium service says they are calling for 20 cm. Any chance of this? Would be great as I would really like to use my snowmobile.

    thanks

    ReplyDelete
  36. Regarding Accuweather storm...

    I work at NWS Grand Forks ND I did see the 00z run of the ECMWF does try to combine an upper system over the central plains and a weaker upper system over Alberta into one larger upper low over western Ontario and gives southern Manitoba precipitation in that Wed-Fri period. That said all previous runs prior did not have this system like the 00z run portrayed it.

    GFS/GEM and other ECMWF basically keep the southern moisture stream well south of us and weakly northern stream over southern Canada with limited moisture. Would tend to buy that scenerio for now..

    I wish for snow...it is all brown down here in the Forks...but pattern is against it.

    ReplyDelete
  37. Check the previous comments...

    I did check the 12z GEM run on the web via the montreal website....and it does now have a low in northwest Minnesota at 00z Dec 15th....not terribly strong....but 12z run does try to at least bring something up and phase the more active southern with the northern jet streams.

    So some hope may be there after all...

  38. Greetings everyone!

    Sorry for the lack of posts lately.. Just back in Winnipeg today after being away for a week in my native Niagara in southern Ontario visiting family. No hint of snow there, with 14C this past Saturday! Looks just like spring out there with waterlogged fields and full ditches. Glad I missed the -25C Monday morning (it was +10C and raining in Niagara at the time! :)

    Will try to get up to speed on the MB weather over the next day or two with some new posts.

    ReplyDelete
  39. Thanks Rob!
    Welcome back to Winnipeg!!

    ReplyDelete
  40. I kid you not, Portage La Prairie this evening went from -8 to +8 then Back to -8 the next hour.

    LOL....

    ReplyDelete
  41. Welcome back to the Peg Rob! You didn't miss much well you were away, we had pretty basic winter weather if you ask me.

    ReplyDelete
  42. I'm guessing that +8 at portage last night was a mistake. Probably meant -8

    ReplyDelete
  43. All I want for Christmas is....A SNOWSTORM...can you deliver Santa??? :-)

    ReplyDelete
  44. Yeah.. this has been a very boring start to winter. That's been good for most people I guess, but not us weather junkies!

    And if you believe the GFS, it doesn't look like any major systems affecting southern MB for the next week or two. We appear to be caught in a split-flow pattern with storms coming in over northern BC and crossing the northern Prairies into Nunavut well to our north, and another storm track pushing into SW US then tracking into the Great Lakes and the Maritimes, well to our south and east. In between.. we're getting nothing.. except alernating spells of mild and cold weather as systems pass to our north and bring temporary influxes of Pacific air across southern MB.

    ReplyDelete
  45. It can stay this way for the next 3 months as far as I'm concerned. Daniel P maybe you need to move up north to get the weather events you wish for. I'm plenty happy not slogging through 2 feet of snow, brushing off my car or playing demolition derby on skating rink condition roads.

  46. I would love a snow storm too.
