Relaxing and calm weather returns, with a chill in store.

 Much of southern Manitoba has experienced a powerful winter storm which left snowfall totals in the 25 to 30cm range in regions of the interlakes, parklands and western sections of Manitoba. Lesser amounts fell in the south the good news however is that the system which affected us has moved off into Ontario, an area of high pressure off in Alberta will create a northerly flow ahead of it. Read on to Find out how that will affect us.




Above: Much cooler weather conditions expected for the day Wednesday thanks to a recent snowstorm that will be inhibiting temperatures from warming too much. Only sitting in the low single digits or slightly below zero. 

Wednesday: During Wednesday much of southern Manitoba will be enveloped in cloud cover, there will be a potential for periods of snow in the early morning hours. As we get towards the afternoon there is a likelihood of off and on flurries into the evening with the risk of freezing drizzle. The only bad news is that the snow cover that is currently on the ground will inhibit temperatures from rising to above zero or our seasonal normals. Much of the region temperature wise will only warm slightly, with a large section of the parklands and western Manitoba seeing highs below zero (0 to -2C). Areas around that including southeast, southwest and parts of eastern sections of Manitoba will see highs a few degrees above zero (0 to 3C). In the evening to overnight. Any leftover flurries will clear the region, mostly cloudy skies expected for a majority of the night into Thursday. Overnight low temperatures will likely stick in the lower minus single digits, mainly seeing the temperature values between -1°C and -4°C. 

Wednesday: Winnipeg: Mainly cloudy with 30 percent chance of flurries and risk of freezing drizzle. Wind north 30 km/h gusting to 50. High zero. Wind chill minus 11 this morning. UV index 5 or moderate. Brandon: Cloudy with 30 percent chance of flurries and risk of freezing drizzle. Wind north 20 km/h gusting to 40 becoming light this afternoon. High minus 1. Wind chill minus 11 this morning and minus 6 this afternoon. UV index 4 or moderate. Dauphin: Cloudy with 30 percent chance of flurries and risk of freezing drizzle. Wind north 20 km/h becoming light this afternoon. High zero. Wind chill minus 9 this morning. UV index 4 or moderate.

Wednesday Night: Winnipeg: Mainly cloudy with 30 percent chance of flurries. Wind north 30 km/h becoming light this evening. Low minus 4. Wind chill near minus 8. Brandon: Cloudy with 30 percent chance of flurries. Wind north 20 km/h becoming light this evening. Low minus 7. Wind chill minus 12 overnight. Dauphin: Cloudy with 30 percent chance of flurries. Wind up to 15 km/h. Low minus 7. Wind chill minus 6 this evening and minus 12 overnight.

Thursday: Looking ahead to the day Thursday it appears that an area of high pressure will approach the province of Manitoba sitting mainly in Eastern Saskatchewan. Mainly cloudy skies are expected for the day on Thursday there is a possibility for a small swath of snow to move through the western portions of Manitoba and particularly the parklands in the afternoon hours. A trace to 2 cm is possible. Good news for Thursday is that the temperatures will finally rise above freezing for a majority of southern sections, looking at the Data it appears that our temperatures will warm into the low to mid single digits (0 to 5C). This will be beneficial as we are looking to hopefully see the snow melt. Heading into Thursday night it appears there may be a small section and extreme south western Manitoba with a potential for some heavy flurries in the evening hours. Clear skies are possible in south eastern Manitoba with heavier cloud cover in southwestern sections of the province with the chance for spotty showers in the evening. Overnight low temperatures for Southwestern Manitoba May see a few patchy areas where temperatures drop above zero. However a majority of southwestern portions of Manitoba will see overnight lows just below 0°C likely -1 or -2°C. 

Thursday: Winnipeg: A mix of sun and cloud. Wind becoming north 20 km/h in the afternoon. High plus 3. Wind chill minus 8 in the morning. UV index 6 or high. Brandon: Cloudy with 30 percent chance of flurries. Wind up to 15 km/h. High plus 3. Wind chill minus 11 in the morning. UV index 3 or moderate. Dauphin: Cloudy with 30 percent chance of flurries. Wind up to 15 km/h. High plus 3. Wind chill minus 11 in the morning. UV index 3 or moderate.

Thursday Night: Winnipeg: Partly cloudy. Wind north 20 km/h becoming light in the evening. Low minus 6. Wind chill minus 10 overnight. Brandon: Mainly cloudy with 30 percent chance of flurries. Fog patches overnight. Wind up to 15 km/h. Low minus 7. Wind chill minus 11 overnight. Dauphin: Mainly cloudy with 30 percent chance of flurries. Fog patches overnight. Wind up to 15 km/h. Low minus 7. Wind chill minus 11 overnight. 

Friday: Southern Manitoba will continue thanks to the presence of an area of high-pressure which will allow a persistent northern flow allowing for slightly cooler temperatures than average. Cloudy skies are forecasted in extreme Southwestern portions Manitoba which may give some off and on showers in the late morning and afternoon. Sunny skies are expected for the day on Friday with a potential for some cloud cover in extreme Southern portions of Manitoba particularly near the border. Daytime high temperatures for the day on Friday will finally rise into the mid to high Single digits (4 to 7C). The only exception being the Manitoba lakes for temperatures which will likely sit in the low single digits (0 to 3C) thanks to cooler lake temperatures and recent snowfall. Friday night expect mostly clear conditions as a result our temperatures will take a plunge below zero again. Our Temperatures will drop, into the low to mid minus single digits (-1 to -5C), areas over the Manitoba lakes may be closer to -7 or -8°C. Friday: Winnipeg: Sunny. High plus 4. Brandon: Sunny, Clearing. High 8. Dauphin: Clearing. High 8.

Friday Night: Winnipeg: Clear. Low minus 7. Brandon: Clear. Low minus 8. Dauphin: Clear. Low minus 8. 

Into the weekend: We will continue to be on the eastern side of an area of high-pressure in Western Canada, A cold front looks to sweep through the region on Sunday night into Monday with a brief temperature drop likely. Will update you on Friday as the weather models come in.  It appears that the warmest weather will remain stateside with they continue to trend of temperatures remaining in the mid to high single digits for daytime highs and overnight lows in the low to mid minus single digits as well. 




Please note that the forecast numbers I use currently are from environment Canada until I can get a better handle on figuring out temperatures from weather models
