Dry most of the week.. cool outbreak looms for weekend..

A nice looking Sunday is on tap today with mostly sunny skies, a westerly breeze and temperatures close to 20C this afternoon. Cooler weather is expected Monday as northwest winds draw in cooler air from the west, with a risk of patchy frost over southern MB Tuesday morning. Dry weather is expected to continue through through mid week although a storm system moving through Dakotas on Wednesday threatens some rain near the US border. (models currently indicate this system should remain south of the border but we'll keep our eye on any changes) By Friday, a low pressure system tracking across the eastern Prairies will usher in a colder airmass for the weekend, with highs only in the low teens expected along with an increasing potential for frost. Looks like fall is coming early this year..

  2. Thanks Jim for the post...and thanks for the high plains climate center graphic.

    Very interesting to see the area of minimum rainfall in the devils lake area to near jamestown then to west of grand forks. That does seem real. DVL AWOS pcpn can be a bit questionable but we do have a newer co-op observer who lives 2 S of DVL who reports now and a weather station at a local radio station there to compare. And they are not far off.

    I sat in on the preliminary climate outlook call from CPC in Washington last week. I must say not terribly informative...but ther consensus of all the guidance they look it is for a cold western Canada and nrn Rockies winter but a wetter one on the eastern edge of the cold dome which might lie somewhere close to our region. Hard to say though. A lot of years thrown about down here for compariable patterns is 1988-89 winter and 2008-09 winter. too early yet really...

  3. That cold front for next weekend looks like a stunner!

    Howling winds and falling temperatures look to be the case on Friday!
    Well see if that is still the case a few days from now!
