Unsettled and windy Transition into Colder Weather

 Southern Manitoba will be off to a rocky start for the second half of the week another area of low pressure will slide through the central portion of Manitoba bring long with it strong gusty winds and the potential for snow and blowing snow as well. A pattern change is on the way too, find out more below . Note the Swan River and Dauphin forecasts will return on Friday or Saturday. 


Wednesday: An area of low pressure will sit over central portions of Manitoba, and will gradually move east throughout the day into Ontario by evening. The day will start off and continue as cloudy for a majority of southern Manitoba. Model data is all over the place at the moment, however looking at the consensus there appears to be a band of freezing rain and mixed precipitation moving through the red river valley during the late morning hours should be in the eastern portion to Manitoba by mid morning. Another band of heavy snow will move east into the white shell by afternoon . Followed by shortly after lunch another batch of rain and snow will move south from the inter lakes into southern Manitoba particularly the red river valley and points east. As that band of rain and snow next moves south east into south eastern Manitoba, expect it to turn over to heavy snow in certain sections. 

One thing of note, winds on Wednesday will be blowing out of the north west and west from 60 km an hour gusting to 90 to 110km/h TROPICAL STORM FORCE WINDS in southwestern sections of Manitoba into the western Red river valley. Winds will be slightly weaker as you head into the red river valley, however they will still be gusting to 80km/h with a small chance of gusts over 90km/ those winds will move east through the afternoon into the evening. (Photo on the left). Temperatures for the afternoon will rise into the low minus single digits (-1 to -5C) in western portions of southwestern Manitoba into northern inter lakes and southeastern Manitoba, with sections in South Central and portions of southwestern Manitoba including interlakes where the temperatures will rise a few degrees above zero (0 to 3C). Winnipeg: Cloudy 60 percent chance of flurries in the morning, then rain mixed with snow beginning in the afternoon. Wind becoming west 60 gusting to 80-90km/h in the afternoon.  High 3C. Brandon: Cloudy, 60 percent chance of flurries in the morning and early afternoon. Winds west/ northwest 60 gusting to 80-100km/h in the afternoon. High 0C.

Wednesday night: An arctic cold front will be moving south throughout the night ahead of this some squalls of snow and small areas of snow and blowing snow will occur. Behind the front an influx of arctic air will drive south into regions of southern Manitoba and Central Manitoba, clear skies calm winds will aid in temperature is dropping low minus double digits for overnight lows (-10 to -17C) with windchills in the low to mid-20s. Areas in southwestern Manitoba will be spared by this only seeing -5 to -10C overnight lows. Winnipeg: Cloudy, Periods of snow mixed with rain ending in the early evening then cloudy with 60 percent chance of flurries. Clearing after midnight. Low -14C, windchill -24C. Brandon: Cloudy 60 percent chance of flurries with blowing snow in the evening . Then clear. Winds 40 gusting to 60km/h overnight. Low -10C windchill -15C. I will say that areas in northern Manitoba will see windchills from -30°C to -46C. 

Thursday: And arctic cold front will be signing south into the Dakotas throughout the day behind it a large area of Arctic air will filter in, as a result expect partly cloudy to mostly cloudy skies in the morning and early afternoon with sunny skies expected towards the later half of the day. No precipitation is expected however. Daytime high temperatures are expected to rise into the low minus double digits to mid minus double digits (-10 to -15C), the colder temperatures will occur over Lake Winnipeg and areas in the interlakes surrounding the lake. Winnipeg: Partly cloudy, high -13C. Brandon: Partly cloudy. High -12C. 

Thursday Night: Another cold front will dive southeast gradually during Thursday night,  another band of light snow will develop and impact the parklands into the Interlakes by morning. Partly cloudy skies mostly cloudy skies are expected overnight. Temperatures for overnight will Stay in the low to mid minus double digits (-10 to -15C) with Varying temperatures as you travel throughout the south. The eastern portion of Manitoba however will see temperatures drop into the -15 to -20C range. Winnipeg: Clear becoming mostly cloudy by morning, low temperature -15°C. Brandon: clear then Mostly cloudy. Low temperature -14C. 

Friday: As mentioned above the cold front will stall out over southern Manitoba during the afternoon, the light area of snow that moved through in the overnight will continue to move through Manitoba through the morning hours. Mostly cloudy skies should be expected throughout the day. Areas along a line from Elkhorn or Virden , Brandon and points east along the trans Canada will be a dividing line between temperatures in the low minus double digits to the North (-10 to -15C) and the high minus single digit temperatures to the south (-5 to -10C). Winnipeg: Periods of snow in the morning then cloudy, high temperature -10°C. Brandon periods of snow ending late in the morning then cloudy. High temperature -10°C.

Friday Night: It looks like an area of low pressure will move east through the region bring another chance for a shot at snow. Consensus is hard to tell at this point how much we will get but it looks like it might be something to watch as we get closer. Overnight low temperatures will drop into the low minus double digits to mid minus double digits (-10 to -15C), then rise into The high minus single digits (-4 to -10C) in the southwest part of the province  . Then the low minus double digits in the south central part of the province (-10 to -13C) . With temperatures remaining in the mid minus double digits in the southeast (-12 to -16C). Winnipeg:Cloudy, flurries or snow beginning by morning. Temperature -13°C rising to -9°C by morning. Brandon: Cloudy periods of snow beginning after midnight, temperature -10°C rising to -7°C by morning.
