It looks like spring is going to take its time moving in this year. The main weather story for this forecast period is cool arctic high pressure, which looks to be the dominant player.
A large ridge of arctic high pressure has been dominating our weather for the last week and looks as if it will stay in control for at least another week. The only thing keeping us from really cold weather is the strong spring sunshine moderating the arctic air. We will start to feel this moderation of arctic air during the second half of this week. With high pressure in place, light winds and plenty of sunshine, temperatures will slowly warm up each day. By Friday we should see high temperatures around +5 C. With the deep snow cover still in place it will be tough for temperatures to get much warmer.
Over the weekend an area of low pressure will track across northern Canada, dragging a cold front behind it. This will slide through our region on Sunday and will drop our daytime high temperatures back below freezing. These cool temperatures will continue into next week.
We will then have to watch an area of low pressure forecast to come in off the Pacific and slide southeastward during the middle of the week. Confidence is not that high in this system, but depending on the strength and track, we could see some more snow next Wednesday or Thursday. Looking further ahead, the weather models are still not showing any big push of warm air. In fact, they lean toward a fairly active pattern that could bring more snow or maybe some rain.
Usual temperature range for this period: Highs, -4 to 9 C; lows, -15 to -1 C.
