Cloudier Second Half Of The Week Coming Up

Brad Leave a comment

Cloudier conditions will be on tap for Winnipeg & the Red River Valley through the remainder of the work week, however with little precipitation expected and seasonal to slightly above seasonal temperatures, conditions will be fairly pleasant.

Skies will be mixed to cloudy across Winnipeg & the Red River Valley today as a complex disturbance in the United States spreads cloud across much of the Southern Prairies. A chance of showers exists along the American border, but further north the chance drops off quite quickly. Winds will be fairly light as temperatures climb to a high near 18°C. Heading through tonight, skies will be partly cloudy to mixed as temperatures drop to a low near 7°C.

With the jet stream riding across the southern Prairies, southern Manitoba will see cloudier conditions with a chance for some shower activity near the American border.

Thursday will likely start with partly cloudy skies, but see more cloud cover move in through midday. Temperatures top out near 18°C with fairly light winds. Expect cloudy conditions on Thursday night as temperatures dip to around 8°C.

Friday is a bit of a wildcard at this point, but it appears that morning cloud will give way to some afternoon sun before more cloud cover moves into the region on Friday night. Temperatures will top out near 19°C with winds out of the east at 20-30 km/h.

Friday night will bring cloudy skies with a good chance of rain as a more organized area of rain moves from southern Saskatchewan and southwestern Manitoba into the Red River Valley.

Long Range

The weekend is looking quite unsettled and wet with rain likely both Saturday and Sunday as a slow moving upper-low moves towards the region. At this point, it looks like there may be a significant convective element to this system, meaning that rainfall amounts could be highly variable across the region. Daytime highs will continue to sit near 17°C through the weekend with overnight lows in the low teens.

Winnipeg’s seasonal daytime high is currently 17°C while the seasonal overnight low is 5°C.

Rainy Friday, Pleasant Weekend

Brad Leave a comment

Rain will be the story of the day for Winnipeg as a stalling low pressure system continues to produce rainfall over portions of Southern Manitoba. The wet weather will give way to a fairly pleasant weekend, however, as a westerly flow develops and spreads warmer air eastwards across the Prairies.

Winnipeg can expect another 5-10 mm of rain today as a slow-moving low pressure system continues to produce a band of rain stretching from the Pilot Mound region northeastwards through the Red River Valley, over the south basin of Lake Winnipeg and off through the Nopiming Provincial Park into Ontario. With the wet weather, temperatures will be near-seasonal as the daytime high sits near 17°C. The wind will be gusty out of the north at around 30 km/h gusting to 50 km/h.

Forecast rainfall amounts from the RDPS for Friday between 7AM and 7PM local time.

The rain will taper off this evening as the low moves off into Ontario. Clouds will then scattered out as the wind gradually tapers off and the temperature dips to a low near 7°C.

Saturday will be a fairly nice day with a high near 20°C under sunny skies. Expect a low near 11°C on Saturday night under clear skies.

Sunday will be a warmer day with temperatures climbing into the mid-20’s as warmer air spreads eastwards across the Prairies. Cloud cover will increase through the day, though, as a cool front sweeps through the Red River Valley in the afternoon. At this point, no rain is expected. Winds will shift from 20-30 km/h out of the south to 20-30 km/h out of the northwest behind the front. Skies will gradually clear overnight as temperatures head to a low near 13°C.

Long Range

Next week is looking relatively unsettled with multiple chances for rain through the week. Temperatures will be near seasonal for much of the week, although it appears that a more pronounced cool-down may come with some rain at the end of next week.

Winnipeg’s seasonal daytime high is currently 18°C while the seasonal overnight low is 6°C.

Warmer Weather Returns Alongside Chance of Rain

With the ridge of high pressure that brought the decidedly fall-like temperatures now moving off to the southeast, temperatures will begin to warm and head back towards seasonal. Although today will bring plenty of sun to the region, a low pressure system is heading our way from Idaho and will bring cloud and a renewed chance for rain for Thursday night and Friday.

A beautiful sunny day, hopefully unimpeded by a rogue cloud bank that should remain in North Dakota, will be in place through Winnipeg & the Red River Valley today. Our very cool start to the day will be quickly forgotten as temperatures climb to around the 20°C mark this afternoon with a southerly wind near 20 km/h. Tonight will be milder than last night with a low near 10°C.

Thursday will bring increasing cloudiness to the region ahead of an incoming low pressure system. A southerly wind once again near 20 km/h will continue to draw mild air northwards and help temperatures climb to a high near 22°C. By evening, an area of rain will likely push into the region from the southwest, with the wet weather continuing overnight as temperatures fall to a low near 14°C.

The GDPS is forecasting a swath of 20-30mm of rain through Winnipeg on Thursday night and Friday, however some other models suggest much less rain and the main swath pushed a bit further southeast.

Friday will be mainly cloudy with a continued chance of rain through Winnipeg and the Red River Valley eastwards to the Ontario border. Winds will shift out of the north as the low pressure system moves into Ontario which will combine with the extensive cloud cover to keep our daytime high to just 16 or 17°C. As skies clear on Friday night, temperatures will dip to a cool low near 7°C.

Long Range

The weekend is looking quite pleasant with dry weather, plenty of sunshine and daytime highs returning to the low- to mid-20’s.

Winnipeg’s seasonal daytime high is currently 18°C while the seasonal overnight low is 6°C.

Unsettled Weather to Start The Week

Brad 3 Comments

A series of low pressure systems will bring two rounds of unsettled weather to the province before calmer weather moves in for the second half of the week.

Today will be a continuation of the humid weather that moved into the region on the weekend with muggy dewpoint values near 18°C persisting as temperatures climb to a high near 27°C. Skies will remain mostly cloudy through the day, although a few sunny breaks might be seen.

The main weather focus for the day will be thunderstorm potential. Any remaining thunderstorm activity from overnight will clear out this morning, but it won't be much of a reprieve before a new batch of thunderstorms develop along a slow-moving cold front sweeping across the Red River Valley. There will be a slight risk of severe thunderstorms with today's activity; primary threats will be large hail and torrential downpours, but a smaller threat of damaging winds also exists.

The RDPS hints at significant rainfall accumulations of ≥ 40-50mm possible after today's thunderstorms.

The thunderstorm activity will clear out through the afternoon and evening hours from northwest to southeast across the Red River Valley & SE Manitoba. Skies will clear out, temperatures will drop to a low near 16°C, and the humidity will begin to be flushed out overnight.

Tuesday will be a beautiful day throughout the Red River Valley as temperatures climb to a high near 29°C. Winds will be breezy out of the west at 20-30 km/h. Expect a low near 16°C on Tuesday night.

The weather on Wednesday will be under the influence of the next low pressure system moving into the region. Through the day, showers will begin spreading into Southern Manitoba beginning in the southwest corner of the province in the morning, spreading into the Red River Valley through the afternoon, and then onwards towards the Ontario border in the evening.

There's still quite a bit of uncertainty on the main precipitation swath, so we'll be keeping an eye on this one as it develops. That said, best indications are for the heaviest accumulations over Parkland Manitoba with up to 25-30 mm of rain, and then lesser amounts south and eastwards as the rainfall takes on a more transient nature.

Long Range

The remainder of the week and heading through the weekend looks quite dry with mostly sunny skies and daytime highs in the mid-20's, so after the system clears out on Thursday morning, there should have plenty of pleasant days ahead!

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