Record Breaking Warmth Impacting Southern Manitoba today, cold air returns for the rest of the week.

 Southern Manitoba get ready to experience a mild day on Monday I know this post is a bit late however I will still have a little bit of a glimpse of what we can expect to see this evening before colder Arctic air moves in on Wednesday there are some concerns this evening as rain is possible over seven sections of Manitoba with the passage of a cold front.  

As I write this a large swath of rain is currently sitting over the Portage La Prairie Regions moving north into the interlakes moving east at about 20 to 30 kilometers an hour, this rain will impact a large portion of the South Central and southeastern parts of Manitoba this evening the unfortunate news is that a lot of this rain may freeze if it does not dry before the cooler air sets in therefore we have a high risk of ice build up on roads and highways.  Temperatures tonight will take a swing down into the low minus single digits from about 11:00 PM to about 6:00 AM onwards there is a high chance that much of the South will be seeing wind chill values around minus 5 to -10C. 

On Tuesday temperatures will soar into the low minus single digits around minus one to minus two degrees celsius for most, in the interlakes to southeast Manitoba. There will be some areas seeing values around the freezing mark or slightly above in the southwest part of the province. Sunny skies are likely for the day on Tuesday with a brief West to northwest wind. On Tuesday night interestingly enough the lakes will be warm enough so that temperatures over areas of Lake Winnipeg and Lake Manitoba will not drop below zero especially if you're closer to the lake shore, areas outside of that specifically all of the southern part of the province except for areas along the border will see overnight lows in the low to mid minus single digits which will be around minus 1 to minus 3 degrees Celsius. 

On Wednesday a trough will sweep from west to east across the southern part of the province leaving behind it a northerly flow which may increase the risk of lake effect flurries or snow showers, mostly cloudy skies are likely for a majority of the day with some sun peeking through at times. The warmest it will get is around zero degrees in the afternoon and the Winnipeg region areas along and South of highway 2 or highway one will see high temperatures above zero degrees celsius areas north of that will only see high temperatures in the low minus single digits around minus one to minus 3 degrees Celsius which is a sharp contrast from the day on Monday with our temperatures seeing values around 7 to about 12 degrees Celsius. During the hours in the evening there will be a temperature drop right after sunset from, our warm values to a colder air mass which will likely envelop the region for the next several days after this. 

Wednesday Night: Temperatures will drop from zero degrees Celsius and slightly below zero to the low to high minus single digits around the evening most will be seeing values between -1 to -8C, areas in the interlakes will be seeing the coldest around sunset with values around minus seven degrees celsius. Areas further south will still be cold with majority of the region seeing, A very cold Arctic air mass the difference in this situation is that there will be No snow on the ground which usually tends to amplify that cold air so even though that our values will be around minus 10 to minus 12 degrees in the morning hours there will be very little wind chill which will prevent it from feeling like December or January.

The second half of the week seasonal temperatures look to return which will help reduce the significant cold that we've experienced during Wednesday, I'm seeing a reprieve on Thursday with our high temperatures returning to the mid minus single digits. Very little precipitation is expected into the second half of the week with only a trace to two centimeters of snow possible if anything occurs, overnight lows on second half of the week will very be between the mid minus single digits to the mid minus teens .

 I do not expect the coldest of the weather until Wednesday.
