What a difference a week can make. The big storm system that hit our region as forecast late last week ended up stalling out and sat over southern Manitoba all weekend, bringing clouds and showers. This system looks like it will be followed by a second smaller but still strong system on Tuesday and Wednesday.
This second system looks as if it will take a similar path as last week’s system but it does not look as if it will be nearly as slow moving. Southern and central regions will likely see around 10 millimetres, with a few areas seeing upwards of 20 mm. There is a chance of some wet snow overnight Wednesday into Thursday morning.
With cool air already in place from the northerly flow behind last weekend’s system, things look like they will get really cool with this second system. If we see clear skies on Thursday, Friday or Saturday night, temperatures could really bottom out. I wouldn’t be surprised to see readings as low as -5 C in some areas. Daytime highs will start off pretty cool, but under the strong spring sunshine we should see them recover back into the low teens by the end of the weekend.
Next week looks to be a little more settled with any major storm systems forecasted tracking by to our south. The models have been having a little bit of trouble with temperatures during this period. They are jumping back and forth between returning to seasonal values with highs in the upper teens to around 20 C and keeping us cool, with highs only making it into the low teens and overnight lows routinely below zero.
Personally, I’m leaning toward a return to mild conditions and I would sure be disappointed if I am wrong.
Usual temperature range for this period: Highs: 10 to 23 C. Lows: -2 to 8 C.
