12.6 cm storm total here in Charleswood.. 12 cm on the ground. Looks like our whitest Halloween here in a number of years.

Snow from this system should start falling over southwest MB overnight into Monday morning, spreading into Winnipeg by midday Monday or early afternoon. Snow will quickly increase in intensity through the afternoon into the evening with 10 cm possible by midnight. The snow will likely begin as wet melting snow in Winnipeg initially as temperatures will be above zero by the time the snow starts, but will drop to the freezing mark as the snow intensifies. The Monday afternoon rush hour could be a sloppy slow one if this pans out. The storm should clear out by Tuesday morning, but it’s not likely that the snow will melt in time for Halloween trick or treating Tuesday evening. Get the boots ready!

Those of you looking forward to a return to pleasant mild weather over Southern Manitoba will likely be disappointed over the next couple of weeks. Guidance is indicating that a large scale Artic vortex over Hudson Bay and Northern Ontario will persist through the next two weeks at least, bringing a continuation of below normal temperatures over Southern Manitoba likely through the end of October. If this occurs, it will mark the first prolonged stretch of below normal temperatures in Winnipeg since May, an indication of how long Winnipeg and Southern Manitoba have been enjoying above normal temperatures this year. At this point, no major storms are forecast over the next week or so over Southern Manitoba, with generally dry but cool conditions. Note that our last El-Nino season in 2002-03 began with the coldest October on record in Winnipeg, but a mild December and January. Perhaps, a similar pattern is developing this year, as a large scale ridge begins to build over the west coast giving pleasant above normal conditions to BC and Alberta this fall, eventually spreading eastward over Southern Manitoba by December.

It's going to be a windy one in Southern Manitoba over the next 24 hours as a deep low pressure system over Northwest Ontario funnels cold northwesterly winds over Manitoba. Winds are already 48 gusting 63 km/h at Winnipeg airport as of noon, and the winds are only expected to become stronger by this evening. It's possible Winnipeg and the Red River valley may experience wind warning criteria with sustained wind speeds of 60 km/h or more by this evening through tonight into Friday with gusts to 70 or 80 km/h. Not a pleasant way to the end the week! The good news is the weekend should see much calmer conditions as a ridge of high pressure builds into the province bringing light winds. Unfortunately it looks like we'll be staying well below normal temperature-wise through next week. After such a beautiful stretch of above normal weather dating back to April, I guess it's payback time for Mother Nature!

Well, the first snow of the season is falling in Winnipeg. A cold rain started around 1:30 pm then changed to snow over the north part of the city by 2:45 pm. By 3 pm, the rain had changed to wet snow over much of the city with visibilities reduced to 1 km or less at times. Here in Charleswood, the wet snow began at 3:09 pm. The wet snow should end by late afternoon with 1 or 2 cm of slushy accumulation likely over grassy surfaces.
Like it or not.. the winter of 2006-07 has begun!
Given 330-340 degree low level steering winds, the lake effect bands will likely set up off the south end of Lake Manitoba through Elie and Fannystelle towards Brunkild. Off Lake Winnipeg, the bands will likely set up over Grand and Patricia Beaches south-southeast towards Beausejour and Vivian. (see map) These lake effect bands could be quite intense if they change into snow as expected. Near zero visibility in heavy wet snow are likely through these bands overnight through Wednesday with local accumulations of 5-10 cm per 12 hours possible. Accumulations will be less if the precipitation is mixed with rain which may be the case close to the lakes where the 11c lake water will warm the low levels enough to maintain precipitation as rain.
The orientation of the lake effect bands will depend on the exact low level wind direction. If the low level winds are more northerly (350-360 degrees), the bands will be a little more west than the map indicates. If steering winds are more northwesterly (300-320) the bands will be further east. Note that a wind of 300 degrees can bring lake effect into Winnipeg off Lake Manitoba.
Whatever the case, looks like an interesting couple of days shaping up as Mother Nature sends us an early taste of winter!

Yuck.. The coldest weather of the fall season so far will be blasting into Southern Manitoba on Tuesday as a sharp cold front moves through from the northwest during the day. Southwest winds in the morning will shift into the northwest by afternoon, which will usher in much colder air from Northern Manitoba. Temperatures will be falling into the low single digits Tuesday afternoon with rainshowers changing to the season's first snowflurries by late afternoon or evening. There could even be some significant lake effect rain or snow bands off the south ends of Lake Winnipeg and Manitoba Tuesday night and Wednesday. The cold weather will persist through the week with cold winds and occasional flurries, a sharp change from the pleasant fall weather enjoyed up to now. Hey, it had to come sooner or later! (although I prefer later..:)

It will be another beautiful fall day over Southern Manitoba on Thursday as sunny skies and southerly breezes push temperatures close to the 20 degree mark. This is in sharp contrast to a year ago when Southern Manitoba was hit by the season's first snowstorm on October 5th that brought 5 to 10 cm of wet snow to Winnipeg and up to 45 cm over southwest Manitoba near Pilot Mound. (see write-up at.. http://members.shaw.ca/wpgwx/robsobs/highlights05.htm) No snow is in the forecast this year as the mild weather is expected to continue into Saturday before a cold front brings in cooler conditions for the remainder of the holiday weekend, but no snow. Milder conditions are expected to move into Southern Manitoba again next week.

..Warm and dry first half.. seasonable second half..
The dryness that characterized the summer of 2006 continued into the first half of September with no rain recorded for the first 15 days of the month. The dryness was also accompanied by some summerlike heat at times with temperatures near or above 30 degrees on several days, peaking at 31C on the 15th. Rain finally arrived on the weekend of Sept 16-17 with 25 to 45 mm of much needed rain in the
Another fine fall day in

Wow.. What a beautiful start to October! Under sunny skies and a nice southwest breeze, temperatures rose to a balmy 26.8C at my Charleswood station today, (26C at Winnipeg airport)... some 12C above normal for October 1st. Felt just like summer out there. Shorts and bike rides were the norm today. It was even warmer south of Winnipeg, with Morden hitting 29C today - the hottest spot in Canada! Should be nice again tomorrow, although not quite as warm.. with highs around 18-20C. Still nice for early October.
