You have to love spring across the Prairies. One day it’s cold and snowy and a few days later it feels like summer! It looks like our spring roller-coaster ride is going to continue, but it does appear the ride is coming to an end. After a beautiful weekend and first half of the week, it looks like this forecast period will begin with a subtle change that will bring some unwelcome cold air by Friday.
An area of low pressure is forecast to track through north-central Manitoba on Thursday, bringing more clouds than sun to southern regions along with the chance of a few showers. This low will quickly move off to the East, dragging a cold front behind it. Arctic high pressure will slide in on Friday, bringing plenty of sunshine but cooler temperatures. Depending on the exact track and timing of this high, there will be a slight chance of frost over eastern areas, but for the most part, overnight lows should stay in the 3 to 5 C range.
Temperatures will quickly recover over the weekend as a weak area of low pressure moves across our region on Sunday. Saturday should see mainly sunny skies with a high in the low 20s. Sunday will likely see a mix of sun and clouds with a high in the mid-20s. Sunny skies and warm weather will continue into Monday and Tuesday as weak high pressure slides through. Under the strong late-spring sun we should see highs in the mid- to upper 20s.
Another area of low pressure is then forecast to move up from the south around the middle of next week, bringing a good chance of thunderstorms on Wednesday and Thursday. Temperatures will continue to be warm, with highs expected to be in the low 20s — unless heavy clouds stick around longer than expected.
Usual temperature range for this period: Highs, 16 to 27 C; lows, 3 to 13 C.
