The above normal temperature pattern which has persisted over southern Manitoba for the past 6 weeks will continue through the weekend into early next week.. but a major pattern change next week will bring an end to the mild weather as a strong push of cold Arctic air floods across the Prairies from the west. This will bring the first real cold weather of the season to southern Manitoba with temperatures in the minus teens and lows in the minus 20s by the end of the week.. a shocking change from the unusually mild weather we have been experiencing since late October (today will mark Winnipeg's 44th consecutive day above normal since the warm weather streak started Oct 21st). But first we'll have to deal with a minor system passing through southern Manitoba Saturday night into Sunday morning that will bring a couple cm of snow along the way. That will clear out by afternoon with a pleasant end to the weekend as temperatures remain well above normal for early December with highs around the freezing mark (normal highs are now -7C with lows of -16C!)
|NAM model valid 3 am Tuesday morning shows potential storm|
system over southern Manitoba with widespread snow
causing significant impact to the Tuesday morning commute
Stormy Tuesday? Things start to get interesting Monday night into Tuesday as a storm system over Montana tracks towards the Red River valley, possibly bringing significant snowfall across southern Manitoba, including Winnipeg. Most models are suggesting that southern Manitoba could be seeing 10-20 cm of snow with this system as well as increasing northwest winds and falling temperatures on the backside of the storm Tuesday. One model however, the Canadian GDPS, is suggesting that the storm will mainly miss southern Manitoba before clipping southeast Manitoba Tuesday night into Wednesday. This solution could easily change over the next few days, so keep up to date on this potential storm system for southern MB that could have significant travel impacts Monday night into Tuesday. Regardless of what happens, be prepared for a big change to significantly colder weather by the middle of next week!
