Cooler With Showers Likely

Brad Leave a comment

Winnipeg will see cooler conditions as unsettled weather continues over the next couple days.

Cool and cloudy conditions will continue in Winnipeg today. A low pressure system lifting northeastwards out of the Dakotas will spread cloud and showers across the Red River Valley through the day. Many areas in the Red River Valley will likely see showers through the day today with accumulations of 10 to 20 mm. Areas of more intense convection with isolated thunderstorms may develop with this system as well, producing localized rainfall accumulations in excess of 30 mm.

The cloudy, wet conditions will keep temperatures cool with a high near 20°C. It will also be a windy afternoon with northwest winds strengthening to 30–40 km/h. Winds will taper off this evening with temperatures dipping to a low near 11°C.

A low pressure system lifting northeastwards will spread showers through southern Manitoba today.

Saturday will bring mixed skies to the region with west-northwest winds of 20–30 km/h. An upper trough moving through the region will bring a chance of showers to the area again through the afternoon, but the increased sunshine will help temperatures climb to a seasonal 25°C. Skies will clear out in the evening with easing winds as temperatures head to around 12°C.

Settled conditions will push into the Red River Valley for Sunday as an upper ridge builds across the Prairies. Winnipeg will see a few clouds through the day and temperatures will reach a seasonably cool high near 22°C. Winds will be breezy out of the northwest up to 30 gusting 50 km/h through the day. As a high pressure system moves into the region on Sunday night, any remaining cloud will clear out, the winds will ease, and temperatures will head to a low near 11°C once again.

Long Range Outlook

Next week is looking great for Winnipeg with more pleasant summer conditions. The city should see plenty of sunshine through the week with near-seasonal temperatures. There may be some chances for thunderstorms with disturbances rippling southeastwards down the upper ridge, but much of that activity would likely be focused more during the nighttime hours.

Today’s seasonal daytime high in Winnipeg is 25°C while the seasonal overnight low is 12°C.

Friday will be when the hot and humid weather settles back into the region. Winnipeg will see temperatures climb to a high near 32 °C and a breezy southerly wind will draw humid conditions northwards. By the end of the day, the dewpoint is forecast to reach almost 20 °C which would make for noticeably muggy conditions.

A cold front will push eastwards across the region on Friday evening into the night. It looks likely that it will support an area of showers and thunderstorms as it moves through.

The weekend will bring more sunshine with a return to comfortable humidity levels. Both Saturday and Sunday will see high temperatures in the upper 20s.

Today’s seasonal daytime high in Winnipeg is 26°C while the seasonal overnight low is 13°C.

Unsettled Friday Followed By A Beautiful Long Weekend

Brad Leave a comment

A cold front pushing through southern Manitoba will bring unsettled conditions today, but a high pressure system will usher in beautiful summer conditions for the long weekend.

Today’s main weather-maker will be a cold front will pushing across the Red River Valley. Winnipeg will start the day with remnant cloud cover from the night’s thunderstorms. Skies will become mixed later this morning as showers and thunderstorms develop ahead of the advancing front. Temperatures should reach a high around 26 °C this afternoon with dew points climbing to a muggy 19 °C.

The unsettled weather will move through in the afternoon, then push off to the southeast in the evening. We do not any severe weather in Winnipeg, but high dew points will likely result in locally heavy rainfall. To the south and east, there’s a chance for isolated severe thunderstorms that could produce large hail alongside heavy rain.

NAM 12hr. Accumulated Precipitation Forecast valid 03Z Saturday August 1, 2020
Much of southern Manitoba is expected to see showers and/or thunderstorms today.

Northerly winds up to 30 km/h will develop this evening behind the cold front, ushering in a drier air mass. Temperatures will dip to a low near 14°C under mainly clear skies.

Behind today’s instability comes a beautiful long weekend. A sprawling area of high pressure will gradually build into the province this weekend, bringing plenty of sunshine and seasonal temperatures. The wind will continue to be breezy out of the north on Saturday, but will ease into the 15–25 km/h range for Sunday.

Long Range Outlook

There’s nothing but beautiful summer weather in the long-range forecast, with mainly sunny skies and seasonal temperatures persisting right into the middle of next week. The second half of the week may bring gradual warming with variable cloudiness.
