A frigid night on tap

A large Arctic airmass has spread over the Prairies, bringing well below normal temperatures across all of western Canada. The core of the cold air is being brought down by a large high pressure system centered over central Saskatchewan this morning. Temperatures under this high were in the minus 35 to minus 40 range this morning with a bone-chilling -44C in Meadow Lake, SK. This high pressure area will build over southwest MB tonight bringing frigid temperatures to southern MB overnight into Friday morning. Expect temperatures to drop to the -35C mark in many areas early Friday morning, with a possibility of -40C temperatures in traditionally colder spots (such as Wasagaming) Fortunately, winds will be light so wind chill will not be a factor. Exhaust fog however will be an issue for the morning commute. Bundle up!

  4. Another 5 to 12 inches of snow for the southern Red River Valley, not good for flooding.

    Wind chill values will probably be in the -40's, however the wind won't be 15km/h, so no wind chill warnings will be issued. I'll let you know my prediction for low temperatures later today.

  5. Wind chill warning for Red river valley.. mainly due to a light northerly drainage winds funneling down the valley up to 15 km/h at times. Really though, winds are pretty light and it's just plain cold..

  6. NWS Grand Forks issued their flood forecast. It calls for a nearly 100% chance of major flooding in Fargo, and about 70% chance of major flooding in Grand Forks and Pembina.

    Models are showing a stormier pattern for next week. The GFS is even hinting at a storm very similar to the one in early February.

  7. Looks like another cold night on tap with lows around -30 C

    Tomorrow looks like a miserable day with -16 C high but that cold south wind will ruin it!
