Forecast – for Dec. 9, 2010

After a fairly quiet weekend and start to the week it looks like we might see more snow move in during the second half of the week as an Alberta Clipper takes shape. The models are showing an area of low pressure moving in from off the B.C. coast on Wednesday and then pushing east. It should move across southern regions of Manitoba on Thursday and will likely bring around five cm of snow to areas around and north of theTrans-Canada Highway by Friday morning.

Arctic high pressure will then slowly build southwards over the weekend and we should see colder and colder air move in each day. Monday morning looks to be the coldest with the centre of high pressure forecasted to be right over us. I wouldn’t be surprised if we see the first -30 C temperatures of the season.

This high is forecasted to continue dropping south and east which means we will see our winds switch over to the southwest later on Monday and along with the winds we will start to see milder air move in by Tuesday.

Low pressure is also forecasted to develop to our west and slowly drift into our region by the middle of next week. This would mean increasing clouds along with the chance of flurries or light snow. The clouds will also help to keep temperature on the mild side with highs for next week expected to be in the -5 to -10 C range with overnight lows around -15 C.

Looking further ahead the models are pointing towards colder weather moving back in but they do not show any strong storm systems affecting our region.

Usual temperature range for this period: Highs: -18 to -2 C Lows: -28 to -12 C
