The biggest problem with last week’s forecast was that the low pressure system expected to zip through the region over the weekend ended up moving much slower. This allowed for several rounds of rain to form and rotate through our region, bringing too much rain to some areas and some much-needed rain to others.
This forecast period looks as if it will start off warm and fairly active and then transition into a drier and hotter pattern. The weather models show thunderstorms developing to our south and west sometime on Wednesday, then drifting northeastward in the afternoon and into the overnight hours. Isolated areas of heavy rain are possible once again with these storms.
Thursday and Friday look as if they will be partly cloudy, with near-seasonable temperatures as a weak area of low pressure slowly slides by to our north. There could be the odd shower thrown into the mix on these two days as well, with the best chances being in the Interlake and over eastern areas.
Over the long weekend the weather models show a ridge of high pressure developing to our west. This should bring mainly sunny skies along with increasing temperatures. Look for highs in the mid- to upper 20s to start the weekend, warming to around 30 C by Monday. This ridge of high pressure is then forecast to push eastward during the week, which would allow temperatures to warm even more, with highs by Wednesday in the low to mid-30s.
Usual temperature range for this period: Highs, 20 to 30 C; lows, 8 to 17 C.
