One Last Day of Warm Weather

Scott Leave a comment

One more day of seasonably warm weather is on the way before conditions cool down. A strong low pressure system will usher in a much cooler air mass by midweek.

This Week

Today will be another warm, but breezy day in southern Manitoba. A strong low pressure system to the west will develop a stiff southerly flow, allowing for these warm temperatures. Rain is expected to develop over western Manitoba by this evening, but only a chance of showers is expected over the Red River Valley and southeastern Manitoba. Skies will generally be a mix of sun and cloud with temperatures in the low to mid twenties.

Gusty southeast winds will remain over southern Manitoba on Tuesday, but temperatures will cool somewhat. Highs are only expected to reach the upper teens, with mainly cloudy skies. Showers will be likely throughout the day, although large accumulations are not expected.

Significantly cooler weather is on tap for Wednesday as a strong cold front swings through the region. High temperatures are only expected to be in the low teens with gusty southwest winds. Skies will be a mix of sun and cloud with a slight chance of a shower.

Long Range

Cooler weather will stick around for the rest of the week behind the departing low pressure system. As shown above, our warmer-than-normal temperatures that were in place through the weekend and early this week will be replaced by below-normal temperatures behind this low pressure system.

High temperatures will likely be near 10C most days, plus or minus a few degrees. While that seems cool, it is only a few degrees below normal for this time of year.

Drying Out with Seasonal Temperatures

After a rainy weekend we’ll have a chance to dry out this week as skies clear. Temperatures will be cool, but generally near seasonal values.

This Week

Today will see mainly sunny skies as the low pressure system from the weekend moves off to the east. However, it will remain quite windy behind the system with northwesterly winds of 40 km/h gusting to 60 km/h. Temperatures will sit in the mid teens over most of southern Manitoba. There will be a slight risk of frost in low-lying areas tonight as temperatures drop rapidly with the light northwesterly flow.

Tuesday will see slightly improved weather over today as winds calm down and temperatures climb up into the mid teens. Skies will also remain mainly sunny, making for a generally pleasant day.

Wednesday should be one of the warmest days this week. Temperatures are expected to climb up near the 20C mark under light southerly winds and mainly sunny skies.

Long Range

Long range models hint at another strong low pressure system developing to our west later this week. It remains unclear if and when this system may affect us, but it likely won’t be until the weekend at the earliest. The good news is that this system will draw up a warm, southerly flow, perhaps giving us a brief stretch of warm weather before it arrives.

Windy Start To A Week of Fall Weather

Fall-like weather will move into Manitoba this week as moderate westerly winds behind a cold front that moved through yesterday usher out any notion of humidity and bring cool nights back to the region.

Today will be a mild day with a high near 21°C in the Red River Valley, but beneath sunny skies will be a moderate westerly winds of 40 gusting to 60 km/h. Expect to see a few less leaves on some of the trees when the day is done.

Strong westerly winds (shown by purples and pinks) will develop over southern Manitoba today.

Winds will taper off this evening as the temperature heads to a low near 9°C under clear skies.

Tuesday will be another mainly sunny day courtesy a ridge of high pressure moving into the region. Winds may pick up to 20-30 km/h in the morning, but will then taper off in the afternoon as the main ridge axis moves into the Red River Valley. Temperatures will climb once again to a high near 21°C.

Temperatures will head to a low near 10°C on Tuesday night with increasing cloudiness as a low pressure system begins to organize south of the border.

Wednesday will bring mixed to mostly cloudy skies to Winnipeg & the Red River Valley. There will be a chance for some light rain near the International border as this weather system grazes along the 49th parallel, but little accumulation is expected at this point. Winds will be out of the north at 15-25 km/h and temperatures will climb to a cooler high of 17 or 18°C.

Expect skies to clear on Wednesday night as temperatures head to a low near 8°C.

Long Range

A fairly strong low pressure system is forecast to develop in the second half of the week, but general consensus at the moment is that it will remain the United States’ problem, leaving us to wrap up the second half of the work week with partly cloudy skies and seasonal highs in the mid-teens. As we head into the weekend, the chance for rain will re-emerge as the weather turns a little more unsettled. At this point, it doesn’t appear that any widespread or major rainfalls are expected.

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

Summer Heat Makes A Return

Brad Leave a comment

Summer-like warmth is on the way back to Winnipeg and the Red River Valley for the second half of the week as a deep southerly feed draws heat northwards out of the United States.

Today will be another pleasant day with seasonal conditions across the Red River Valley as the ridge of high pressure that brought pleasant days to the region continues its gradual trek across the province. Winds will continue light with daytime highs around 24°C and comfortable humidity. Tonight will see a seasonable 10°C for the overnight low.

A warm front will be pushing eastwards across Manitoba on Thursday.

Thursday will mark the return of hotter weather as a deep southerly flow develops ahead of a strengthening low pressure system in Alberta. Morning will bring a few clouds as a warm front pushes eastwards across the valley, bringing with it a chance for some showers or perhaps even a thundershower. After the warm front pushes through in the morning, winds will pick up out of the southeast through the remainder of the day to around 30 km/h by late afternoon. Those breezy southerly winds will draw warmer air northwards, pushing Thursday’s daytime high up to near the 28°C mark under partly cloudy skies in the afternoon.

Thursday night will be significantly milder than the past few nights as the warmer air in the region combines with breezy winds that persist through the night to keep the overnight low from dipping much below the 17 or 18°C mark. Skies will be mixed overnight, but no precipitation is expected at this point.

A strong pressure gradient in place over Southern Manitoba will bring windy conditions on Friday.

Friday will be a mild and windy day. Southerly winds of 40 gusting to 60 km/h will be in place over the valley for much of the day under partly cloudy to mixed skies as temperatures climb once again to around the 28°C mark. Friday night will be another mild one with an overnight low near 19 or 20°C with breezy southerlies continuing.

Weekend Outlook

This weekend will bring another mild, although likely unsettled, day on Saturday with a surge of humidity ahead of a cold front bringing the chance for some thunderstorm activity. Sunday looks cooler and drier with highs in the low 20’s and mixed skies.
