Brad Leave a comment

Winnipeg will see below-seasonal temperatures for one more day before a gradual return to summer heat.

A ridge of high pressure moving into the region will continue to keep things cool and breezy in Winnipeg today. With mixed skies, the city should see temperatures climb to a high near 15°C with north-northwest winds of 20 to 30 km/h. The winds will ease this evening with clearing skies. Temperatures will be quite cool with the low dipping to around 1°C at the airport and closer to 3 or 4°C downtown.

The high pressure centre will drift south of the region on Saturday, leaving behind sunny skies and light west-northwest winds. With all-day sunshine, temperatures will be a bit warmer with a high near 20°C. Skies will stay clear on Saturday night with a low near 6°C.

Summer temperatures will return to the Prairies by Sunday.

Warmer weather will continue to edge eastwards across the Prairies on Sunday. Winnipeg will see temperatures return to a seasonal high of 23°C under partly cloudy skies. Winds will be light for much of the day before picking up late in the afternoon into the 20 to 30 km/h range. Temperatures will stay mild on Sunday night with a low near 13°C with the southerly winds continuing. There will be a chance of showers or thunderstorms overnight as a warm front pushes across southern Manitoba.

Long Range Outlook

Next week will bring hot summer weather back to Winnipeg with highs in the 25 to 30°C range. There may be several chances for showers or thunderstorms through the first half of the week, then quieter conditions are forecast until a low moves through next Saturday.

Today’s seasonal daytime high in Winnipeg is 22°C while the seasonal overnight low is 8°C.

Summer Warm-Up Finally Arrives

Brad Leave a comment

Winnipeg will see temperatures climb into the 20’s this weekend as the Arctic grip on the region finally ends.

The city will see one more cool day as a ridge of high pressure moves through the region behind yesterday’s rain. A cold front will push through this morning, ushering in northerly winds near 20 km/h. Skies will stay mainly sunny as temperatures climb to a high near 15°C. Winds will ease this evening with a low tonight near +4°C. A few clouds will move into the region overnight as warmer air begins moving into the region.

On Saturday, temperatures will climb to around 21°C with partly cloudy skies. There may be a slight chance of a shower early Saturday morning as some nocturnal convection moves across southern Manitoba. While it’s always difficult predicting where exactly nocturnal convection will develop, it looks likely that any showers will stay north of Winnipeg. With light winds through the day, it will be a great day to get outside and enjoy the weather! Skies will clear on Saturday night as temperatures dip to a low near 8°C.

More summer-like temperatures will begin to spread across the Prairies this weekend.

Sunday will bring even warmer weather to the region with a high near 23°C. It will be windier than Saturday with southerlies strengthening into the 20 to 30 km/h range. The region will see mainly sunny skies, but some cloud will likely begin building in from the west through the evening. Temperatures will dip to a low near 11°C.

Long Range Outlook

Next week looks like the first notable surge of summer conditions this year. A warm front is forecast to push northwards through the region on Monday as a persistent southerly flow develops over the eastern Prairies. Temperatures could reach the upper 20’s on Tuesday with dew point temperatures climbing above 10°C. Temperatures will stay mild through the rest of the week, but unsettled conditions are likely as a large upper low slowly moves eastwards through the province.

Today’s seasonal daytime high in Winnipeg is 20°C while the seasonal overnight low is 5°C.

Cold Weekend Ahead

Brad

While we often try to be optimistic about the forecast, there’s no getting around it. This weekend’s weather will be lousy.

A persistent vortex over eastern Canada combined with a stationary upper ridge over the west coast will keep Manitoba locked into a regime of cool temperatures.

Today will be the “nicest” day of the next few with sunny skies and a high near 9°C. This is almost 10°C below seasonal averages and it’s going to get even cooler yet. Winds will be out of the north at just 10 to 20 km/h. A low moving through Saskatchewan will spread cloud into southern Manitoba tonight as Winnipeg’s low dips to around -2°C.

Saturday will be a cloudy day in Winnipeg with northerly winds strengthening to 30 gusting 50 km/h. Conditions should stay dry in the Red River Valley with any rain showers or snow associated with the low moving out of Saskatchewan remaining over southwestern Manitoba. Temperatures in Winnipeg will climb to around 9°C, then to near -2°C tonight as the cloud begins to break up. The winds will ease this evening.

This forecast map of 850 mb temperature departures from normal show the huge extent of the below-seasonal temperatures (blue/purple) expected this weekend in the northerly flow west of the Eastern Canada vortex.

Sunday will bring mixed skies to Winnipeg with north winds increasing back to 30 gusting 50 km/h and a high near 6°C. Skies will clear out on Sunday night with a low near -6°C.

Long Range Outlook

Anyone hoping to see more seasonal, spring-like weather is going to need patience. The cool conditions will persist through much of next week. Temperatures should return to the teens by mid-week, then continue warming to seasonal values by the end of the week. No major precipitation events are in the forecast.

Today’s seasonal daytime high in Winnipeg is 18°C while the seasonal overnight low is 4°C.

Sunny and Cool Conditions Ahead

Brad

Winnipeg will see copious amounts of sunshine through the rest of the week, but seasonably cool temperatures have settled into the region.

Winnipeg’s forecast for the coming days is short but sweet: sunny. Other than a few passing clouds this morning, skies should stay essentially clear for the coming 3 days. Highs will slump to around 10°C with overnight lows dipping below freezing each night.

GDPS 2m Temperature Anomaly Forecast valid 00Z Friday May 8, 2020
Forecast temperature departure from normal. While parts of the western Prairies will see seasonably mild conditions, Manitoba will be locked into cooler weather.

Winds will be a bit breezy out of the north today at 20 to 30 km/h. Thursday will be the windiest day of the next three with northerly winds strengthening to 30 gusting 50 km/h. Winds will be lighter on Friday out of the north at 15 to 25 km/h. Winds will ease to light each of the coming nights.

Long Range Outlook

This cool weather is the result of a persistent upper-level flow that has ridging over the west coast and troughing over Hudson Bay and the eastern Arctic. This setup results in a north-northwest flow over Manitoba that supplies plenty of cool air to the region. This will continue until this upper-level pattern breaks down.

Unfortunately, there won’t be any major changes until sometime in the middle of next week when the Hudson Bay vortex begins to shift and break down.

Today’s seasonal daytime high in Winnipeg is 18°C while the seasonal overnight low is 4°C.
