When we have a quiet weather pattern with no strong systems affecting our region, it can sometimes be a little tough in the late winter and early spring to figure out just what will happen in regards to the weather. While last week’s forecast wasn’t too bad, it did miss out on a lot of the little details that resulted in temperatures being warmer than anticipated.
It looks like this quiet weather pattern will continue for most, if not all, of this forecast period. There is currently a split flow in the jet stream, with one stream well to our south and the other just to our north. A split stream usually means storm systems following either of the streams will not be that strong. Add in that we are in between the two storm tracks, and the result is not a lot of active weather.
A storm system will track along the southern stream during the second half of this week. It will be too far away to have any direct effect on us, but it will pull slightly cooler air into our region. This means that on Thursday and Friday high temperatures will likely only be in the -8 to -10 C range.
An area of low pressure is then forecast to form to our west over the weekend and then track only the northern branch of the jet stream. This low will begin to draw in milder air over the weekend, and as the low approaches Manitoba on Monday or Tuesday, southern regions will likely see high temperatures around the 0 C mark. Depending on the track and strength of this low, southern regions could see some light snow as the low passes by but not much in the way of accumulation is expected.
Cooler high pressure will build in behind this low during the middle of next week, resulting in high temperatures falling back into the -10 C range.
Usual temperature range for this period: Highs, -13 to 0 C; lows, -27 to -10 C.
