The Chill Returns

We’ll see a return to colder weather this week, though it won’t be quite as bad as what we saw earlier this month.

A large arctic high will bring colder weather to southern Manitoba early this week. The arrows indicate the clockwise circulation around the high.

Monday

Monday

Clearing
-22°C / -30°C

Today will be our coldest day in awhile. High temperatures will remain stuck in the minus twenties, with a breezy north-west wind. As a result, wind chill values will remain in the -30s for most, if not the entire day. But on the bright side we’ll see sunny skies return, as the lingering cloud cover clears out during the day.

Tuesday

Tuesday

Mainly cloudy. Chance of flurries.
-16°C / -23°C

It looks like we’ll see a slight warm-up for Tuesday with temperatures climbing into the minus teens. The wind will also be light, making it a decent day overall. We may see a few flurries on Tuesday, but they won’t amount to anything of great significance.

Wednesday

Wednesday

Mainly Sunny
-21°C / -31°C

The weather will turn cold again on Wednesday as another arctic high drops south into the region. High temperatures on Wednesday will once again remain in the minus twenties. It also looks to be a somewhat windy day, generating chilly wind chill values in the -30s yet again.

Long Range

The long range forecast continues to look very up and down. Models suggest we’ll see more cold weather over the next 7-10 days, but also some warm days mixed in here and there. No major weather systems are in the forecast, but we’ll likely see little systems bring us small dumps of snow every once and awhile.

Mild Weather Continues

The warm weather from the weekend will continue into this week. High temperatures at or above zero will continue.

850mb temperatures will be around 8C in Southern Manitoba on Tuesday

Temperatures will drop off slightly on Monday compared with Sunday as the wind switches to a more westerly direction. High temperatures will be held down a bit as cooler air moves in from the vast expanse of snow covered land to our west. Highs will generally be in the -4 to 0C range over Southern Manitoba, with more widespread above zero temperatures in south-eastern areas. On Tuesday most of Southern Manitoba should get above zero, with the exception of heavily snow covered areas which will hover close to the freezing mark. Warm air just above the surface (seen in the graphic above) will offer the potential for high single digit or even low double-digit temperatures in snow-free areas if it can stay sunny (mainly south-eastern Manitoba). Southern Manitoba should once again remain mainly above freezing on Wednesday as a light south-easterly flow allows warm conditions to continue.

Current forecasts show a low pressure system sliding through Manitoba on Thursday. This system will bring more snow to parts of Manitoba, though it is unclear at this point if Southern Manitoba will see any significant amount of the white stuff. What does appear likely at this point is that colder air will be pulled down as this system passes through. As a result colder conditions are expected on Friday and may last into the weekend. More details on the potential impact of this system will be available in Wednesday’s post.

Enjoy one of the last mild stretches before our real winter sets in!
