The warmest weather we’ve seen all year is shaping to move in today and persist through the next week as a upper ridge begins to build in over the Prairies. The heat and humidity will be here in full force with daytime highs climbing over 30°C and dew points climbing into the upper teens or even perhaps the low 20’s.

Friday

30°C / 15°C
Mainly Sunny

Saturday

33°C / 17°C
Mainly sunny with a slight risk of a late day thunderstorm.

Sunday

30°C / 17°C
Mainly Sunny

We’ll see beautiful sunny skies today as our temperature climbs to around 30°C. The humidity will become more noticable as the day wears on as the dew point climbs from the low teens to around 17 or 18°C. Temperatures will drop to around 15°C tonight under clear skies.

Tomorrow looks to be a scorcher of a day. The temperature will climb into the low 30’s with high humidity as the dew point climbs over 20°C. It will feel closer to 38–40°C by the afternoon as the Red River Valley bakes in the warmest temperatures of the year. A disturbance will be moving through the Interlake region that will bring a very slight risk of a thunderstorm late in the day, although at this point it looks like most of the activity will stay north of the Red River Valley. Beaches along the South Basin of Lake Winnipeg will have a greater chance of seeing thunderstorm activity than we will here in Winnipeg, so if you’re planning on camping north of the city, that may be something to keep in mind. We’ll have updates below in the comments on the thunderstorm potential tomorrow. We’ll head to an overnight low of aroun 17 or 18°C Saturday night.

Sunday also looks to be a gorgeous day. The hottest weather will be off to our east, but we’ll still see temperatures climb to around 30°C under sunny skies. There will be more of a westerly component to the winds which will help flush out some of the humidity through the day.

Next Week

Next week looks to keep the heat. While the upper ridge flattens thanks to a couple disturbances that move through on the weekend, it’s set to rebound by mid-week, which will keep our daytime highs in the upper 20’s or low 30’s for what looks like the entire week. At this point it looks like we may see some showers or thunderstorms on Monday evening/night, but after that current indications are that it will be hot and dry for the remainder of the week.

After 4 weeks of below-normal temperatures, get out there and enjoy the heat wave! Just be sure to practice some heat safety and wear hats and drink plenty of water. Have a great weekend!
