It just seems to be that kind of year. We saw yet another upper low drop into our region last weekend, bringing with it some record-cold temperatures on Sunday. Winnipeg’s official high temperature on July 13 was 15.7 C, which easily broke the previous record for the lowest daily high of 16.7 C, set back in 1950 and 1884. Fortunately, it looks like summer weather will be moving back in and hopefully this will be the end to these unusually strong systems.
High pressure should be firmly in place by the middle of this week. With the strong summer sunshine, temperatures should moderate a little bit each day this week, with highs pushing the upper 20s to low 30s by the end of the week. This area of high pressure will slowly slide off to our southeast by the weekend, while an area of low pressure will begin to organize itself to our west.
The weather models show a small piece of energy from this western low sliding through central regions sometime on Saturday or Sunday. This will likely bring a mix of sun and cloud along with the chance of a few scattered showers or afternoon thundershowers. Temperatures should remain warm, with the main area of the low remaining to our northwest.
This western low is then forecast to slowly track across the northern Prairies during the first half of next week. It should stay far enough away that southern regions will be mainly sunny, with central areas seeing a mix of sun and cloud. Being on the south side of the low, temperatures will continue to be warm, with highs expected to be in the upper 20s and lows in the mid-teens. Let’s keep our fingers crossed that this low doesn’t decide to drop straight south like the last system. If it does take a more southerly route, then clouds, showers and cooler temperatures will be the rule next week.
Usual temperature range for this period: Highs, 22 to 31 C; lows, 9 to 17 C.
