Stonewall residents can expect a wet and windy Monday before a stretch of sunny, warming weather settles in for the rest of the week. Environment Canada is calling for a 60 percent chance of showers today, July 20, 2026, with a risk of afternoon thunderstorms. The unsettled conditions are linked to a cold front moving through the area, according to Rural Roots Canada.
Wind gusts could reach 60 km/h, so it might be a good day to secure any loose outdoor items. At 10:00 a.m., it was mostly cloudy and 22.6°C at the Winnipeg Richardson International Airport observation site, with humidity at 74 percent.
The unsettled weather is part of a broader severe system affecting central and southern Manitoba today. According to Rural Roots Canada, a surface low near Flin Flon is creating conditions that could bring large hail, damaging winds over 100 km/h, and even a tornado threat to the region.
Conditions are expected to clear tonight, with a low of 13°C. Tuesday will bring mainly sunny skies and a high of 24°C, kicking off a warming trend that will see temperatures climb through the week. Environment Canada forecasts highs of 27°C on Wednesday and 30°C on Thursday, both under sunny skies.
The warmest day looks to be Saturday, when the mercury could hit 34°C under a mix of sun and cloud. Heat warnings may be issued for southern Manitoba as the temperature peaks. However, it won’t be entirely dry; the jet stream pattern will keep the door open for near-daily thunderstorm risks, according to Rural Roots Canada, so residents should stay alert even as the heat builds.
For those planning outdoor activities, getting through today’s showers and wind will be the main hurdle before a mostly pleasant and warm week ahead.
