See what happens when you pat yourself on the back? Mother Nature tends to put you right back in your place! Last week it looked as though the ridge of high pressure forecasted to track across Manitoba would weaken. Well, the ridge did track across our region, but remained very strong, and instead of seeing highs around the 20 C mark, we saw highs soar into the mid- to upper 20s across pretty much all of Manitoba.
Well, it looks as though the summer-like temperatures are going to be a thing of the past, as a large and deep area of low pressure develops over central North America and takes up residence over Hudson Bay during this forecast period.
While this low develops we’ll also see a ridge of high pressure develop over the West Coast. This will help to “dig” or strengthen the area of low pressure to our northeast. The overall result of this setup will be similar to what we experienced earlier this month when the same weather pattern developed.
By Wednesday or Thursday of this week we’ll be in a strong northwesterly flow that will bring down plenty of cold air. High temperatures during the second half of this week and into the weekend will have a tough time making it to the 10 C mark, especially if we don’t see much in the way of sunshine. Overnight lows will be around the freezing mark, or colder if the skies clear for any length of time. Any precipitation looks to be light and, once again, depending on the timing, we could see a few flakes of snow.
Thanksgiving Day looks like it will be cool and cloudy with a few showers or flurries kicking around. Temperatures then look like they’ll bottom out on Tuesday and Wednesday of next week as high pressure builds in. Looking further ahead, the models show a warming trend to begin during the second half of next week.
Usual temperature range for this period: Highs, 8 to 19 C; lows, -3 to 6 C. Probability of precipitation falling as snow: 10 per cent.
