The above-normal temperature streak we’ve seen the past few days will continue through the rest of the week – albiet at a slightly moderated level – until a more unsettled pattern develops for the weekend.
Today & Tomorrow
26°C / 11°C
Mainly sunny.
26°C / 13°C
Sunny.
We’ll see mainly sunny skies the next couple days as a ridge of high pressure slides across the province in the wake of the cold front that pushed through last night.
This ridge of high pressure will bring a break from the 30°C+ weather we’ve had the past couple days, bringing us back down to closer-to-seasonal temperatures in the mid–20’s. We should reach about 26°C each day which is still a couple degrees warmer than the seasonal average of 24°C for this time of year. The evenings will be quite cool, generally near 10–12°C although temperatures could potentially dip into the single-digits tonight in some areas.
Friday
27°C / 17°C
A mix of sun and cloud; slight chance of showers or thunderstorms.
We’ll see a regime change come Friday as a leading impulse approaches the province ahead of a developing long-wave upper trough over the west coast. A southerly flow will redevelop ahead of this impulse pushing moisture northwards out of the Northern Plains back into Southern Manitoba; as such, we’ll see a noticable increase in humidity as temperatures climb to around 26–28°C.
Precipitation is a bit of a wildcard at this point; some models bring a wide area of rain and thundershowers into the Red River Valley in the morning and persisting through much of the day until the impulse moves into NW Ontario while others keep much of the rain north of the RRV in the Interlake and bring thunderstorms in during the evening hours.
I think that most of the precipitation will push north of the city, but I certainly can’t rule it out at this point. We’ll definitely see a mix of sun and clouds, though. It looks like a chance for thunderstorms will persist through much of the evening and into the overnight period as well.
Long-Range Outlook
This weekend we’ll see warm, humid and generally unsettled weekend ahead with showers and thunderstorms likely Saturday & Sunday in Southern Manitoba.
Looking to next week, we will continue to see above-normal temperatures as a slack or southerly flow persists. We’ll also see dew points in the high teens making it feel relatively humid as well. After a month of below-normal temperatures, it looks as if we get to enjoy a late summer after all!
