Winnipeg will see morning showers and widespread smoke today as a low pressure system passes by the region. Much more pleasant weather will return for the rest of the week and the start of school.
After the night’s heavier rain, a few showers or thunderstorms will drift northeastwards early this morning, clearing out of the Red River Valley as a low pressure system moves into Ontario. In its wake, widespread smoke will linger through much of southern Manitoba. This will give very poor air quality to the region and has resulted in a special air quality statement from the MSC. Winnipeg will likely see mainly cloudy skies today, though some late-day sun is possible. It will be a cool day, though, contrasting with the weekend heat as the daytime high only climbs to around 20 °C. Breezy northerly winds will abate this evening as skies clear. Temperatures will head down to a low near 10 °C.
Heading into the rest of the week, a steady and relatively stable pattern develops for the Winnipeg area. With a generally zonal flow aloft and disturbances tracking well to the north, conditions will trend fairly sunny throughout the Red River Valley. Smoke may be noticeable on a couple days through the rest of the week, but it’s unlikely to get anywhere near as bad as Tuesday’s conditions. And temperature-wise, there’s no complaints for the rest of the week with near-seasonal values expected. Highs will sit in the low 20s with lows dipping into the upper single digits.
Long Range Outlook
It currently looks like more of the same in the Red River Valley for the weekend and start of next week. Smoke will be the only wildcard in the long-range forecast, so we’ll keep our eyes peeled in case the potential for another bout of poor air quality arises.
After today’s smokey weather clears out, enjoy the beautiful late-summer weather!
Today’s seasonal daytime high in Winnipeg is 21 °C while the seasonal overnight low is 8 °C.
