During the last week or so we’ve seen one of the more active weather patterns so far this winter and early spring. For this forecast period it looks like the more active weather will be staying to our south. This will mean less precipitation, but cooler conditions.
This forecast period begins with a major storm system developing over Colorado and pushing into Minnesota on Wednesday. The weather models have been slowly trending southward with this system, so the likelihood of it having a major impact on our region is small. Extreme southern and eastern regions may see some light snow on Wednesday, with all regions seeing scattered flurries on Thursday as the system winds up over Ontario and cold air begins to move in behind it.
Arctic high pressure is then forecast to slowly drop southeastward on Friday and Saturday, bringing plenty of sunshine along with cold temperatures. We can expect daytime highs struggling to make it to the 0 C mark in spite of the strong spring sunshine. Overnight lows will be cold, as the clear skies and arctic air allow temperatures to drop into the -15 C range. The good news is that this high looks like it will move off to the east fairly quickly, allowing milder air to work into our region by Sunday.
Temperatures by Monday should be back around average, with highs in the +6 C range and overnight lows around the 0 C mark. Another Colorado low is forecast to develop and take a similar track to the last one during the middle of next week. We may see some showers or light snow develop Tuesday before the main system gets organized on Wednesday. As with any Colorado low, this system will need to be watched, but as usual, confidence this far out in the forecast is low.
Usual temperature range for this period: Highs, -1 to +11 C; lows, -12 to 0 C.
