Warmer than average winter weather continues, winter. Extreme cold wallop to come ???

Manitoba will continue to experience a warmer than normal temperature pattern over the coming days. Multiple low pressure systems coming in from Alberta and Saskatchewan look to traverse across the prairie provinces into the weekend. As they sit over the region it’ll bring a strong southerly flow with mild temperatures and strong wind gusts. A pattern change looks to come, but when ?? Read on to find out more.





Tuesday: Will be one of those cloudy days an area of low pressure will be sitting over the central portion of the province Manitoba. Chance at some off and on flurries throughout the afternoon and early evening otherwise mostly cloudy skies can be expected. An exception will be in areas in northern Manitoba where a large area of snow will be impacting portions north of Thompson including Thompson north into Churchill. Unfortunately much of Manitoba will be missing out on the double digit temperatures expected in southern Saskatchewan on the plus side, however we will likely see temperatures in the mid to high minus single digits in the afternoon. A few areas in SW Manitoba may see values a couple degrees above freezing. Generally (2 to -7C) can be expected for daytime highs. Except for extreme northern portions of the province will get temperatures in the mid to high minus double digits North of Thompson. Winnipeg: Cloudy, 30% chance of flurries in the afternoon. High -4°C. Brandon: cloudy 30% chance of flurries in the afternoon high -1°C. Dauphin: Cloudy, 30% chance of flurries in the afternoon high +1°C. Thompson: Hi -6°C. Cloudy, snow beginning in the morning. Amount 5 cm.

Tuesday night: Cloudy skies are expected for the entire province of Manitoba overnight, the only exception will be that a large area of heavy snowfall which could bring up to 15cm of snow, will be occurring in northern  portions of Manitoba. Snow will only occur from the Northern border into areas just south of Thompson not including The Pas. Areas of southern Manitoba will not experience any snowfall overnight. Of concern is a cold front moving through the overnight which may interact with warmer air above the surface, creating a risk for freezing rain overnight in central portions of the province just south of Thompson into southern sections particularly just north of Winnipeg. Temperatures throughout the night will drop into the mid to high minus single digits for a majority of Manitoba, (-5 to -10C). Windchills in the inter lakes ,red river valley , central Manitoba will be between -10 to -15C. A section of only high minus single digits windchill will occur from the parklands, southwestern Manitoba just south of Thompson. Areas along highway 6 into Thompson will see overnight lows in the mid to high minus double digits with windchills in the (-20 to -35C) range. Winnipeg: Cloudy: 30% chance of flurries, overnight with a risk of freezing rain. Low -5C. Windchill -10C. Brandon: Cloudy, low -10 Dauphin: Cloudy. Low -4C. Thompson: Cloudy, snow at times heavy,  Low -10C. Windchill -20C overnight. 

Wednesday: A low pressure system will be moving through the entire portion of Manitoba during the day on Wednesday.  There is some model disagreements looking between the NAM and the RDPS, RDPS looks to be less potent when it comes the snow in northern sections of Manitoba during the morning. Regardless I would still expect a large area of snow mixed with rain and freezing rain in the afternoon hours from the inter lakes into SW regions. A small band of freezing rain is possible in south western Manitoba into the red river valley by evening hours. Temperatures for a majority of the region from just south of Thompson all the way to the American border not surprisingly will see highs again in the mid minus single digits (-3 to -7C). Areas along the western border of Manitoba into northern Manitoba can expect to see windchills of (-10 to -15C), with (-15 to -25C) windchills in northern Manitoba.  And in extreme northern regions (-25 to -35C). Winnipeg: Cloudy, 60% chance of flurries in the morning then snow beginning in the afternoon, risk of freezing rain in the afternoon and early evening. High -3C temperatures falling to -5C late in the afternoon. Brandon: Cloudy, snow mixed with freezing rain beginning in the early afternoon. High -3C, temperature falling to -6C late in the afternoon. Dauphin: Cloudy, Periods of snow beginning late in the afternoon. High:-4C. Temperature falling to -6C in the early evening. Thompson: Cloudy, periods of snow high -12°C, windchill -19°C. 

Wednesday night: Any residual snow or freezing rain is expected to taper off gradually through the evening. The area of low pressure will depart into northwest Ontario and Minnesota leaving a very cold arctic air mass behind the cold front. This is what will allow a transition into colder than normal temperatures. Clear skies will also contribute to this very cold arctic air mass. Areas of northern Manitoba will be the first to experience the cold it is expected that that will filter south through the night. Temperatures by region, Areas of Southeastern Manitoba will escape the extreme cold with only lows from -5 to -10C (windchills -10 to -14C) for the Red River Valley Interlakes Central Manitoba western Manitoba and areas up to the highway six Corredor heading towards Thompson . will see -10 to -20C overnight lows. The -20 to -30°C windchill‘s will be occurring over the Lake’s Southwestern Manitoba into northern portion of the province. The more -10 to -20°C windchills are forecast in the Red River Valley, Interlakes including the parklands and eastern Manitoba. Areas of Extreme northern Manitoba will be experiencing the worst of the cold -20 to -35C (windchills -30 to -45C). Winnipeg: Clear, low -10C. Windchill: -19C. Brandon: Clear, low -13C. Windchill -24C. Dauphin: Clear. Low -13C. Windchill -20C. Thompson: Clear low -19C, windchill-28C. 


The second half of the week: Looks like the high pressure system and arctic air mass will continue to filter into Manitoba, this will contribute to daytime highs well below normal in the mid to high minus teens in the south with windchills in the minus 20s. Mid minus 20s in the north with windchills below -30C.  Overnight Lows will be in the high -20s in the north with windchill‘s well into the -30s and -40s. Overnight lows will be in the high minus teens to  -20s in the southern half of the province with windchill‘s in the low -30s. The bad news is that the cold looks to increase as we head towards the weekend what this means is that we will start seeing temperatures well below average. There is a good indication that we will see temperatures in the -20s or -30s with windchill’s in the -30s to -50s. More details arriving on the Friday afternoon weather blog.
