Mild November Weather Continues, Cooler Later This Week

Brad Leave a comment

Winnipeg will continue to see very mild November temperatures into mid-week, then a cold front will sweep through and bring seasonal temperatures back to the region.

RDPS 2m Temperature Forecast valid 21Z Wednesday November 2, 2022
A low pressure system will push very mild temperatures into southern Manitoba on Wednesday afternoon.

The warm weather will continue for Winnipeg as a southerly flow continues to draw mild air into the region. The skies will be partly cloudy in Winnipeg with a high in the mid-teens. As the day progresses, an upper trough will dig southwards over the Rocky Mountains. This will push more warm air northwards over Manitoba and keep overnight lows very warm (for November). Winnipeg will only dip down to around 10 °C tonight, a whole 15 °C above normal for this time of the year!

Skies should stay partly cloudy into Wednesday, but its shaping up to be a gorgeous November day. It will be a bit windy as a low pressure system developing building into SW Manitoba brings southerly winds up to 30 to 40 km/h. The upside will be the warmth, with highs climbing into the upper teens and topping out at 18 or 19 °C here in the city.

The low will pass on Wednesday night, but the cold front will stay to the west a little bit longer. While the low will bring cloud to the area, the precipitation associated this system will stay well to the west and north. Winds will shift to the west overnight with a low down into the mid-single digits.

The cold front will swing through early Thursday, shifting winds to the northwest and keeping skies cloudy for the day. Winnipeg will see temperatures recover only a few degrees with just a slight chance of a scattered shower or two. Everything should clear out on Thursday night with temperatures dropping to a near-seasonal low of -4 °C.

Long Range Outlook

Friday will bring some sunshine and near-seasonal temperatures to the region, followed by slightly warmer weather on Saturday. Things will shift beginning Sunday, though, with most weather models showing a transition to cooler weather with the first real chance of accumulating snow beginning next Monday.

Today’s seasonal daytime high in Winnipeg is +4 °C while the seasonal overnight low is -5 °C.

Warm Weekend Ahead; Halloween Looks Great

There are no complaints here about the upcoming weather in Winnipeg: plenty of sunshine and mild temperatures!

RDPS 2m Temperature Forecast valid 21Z Monday October 31, 2022
It continues to look like Winnipeg will see a beautiful Halloween this year with highs in the mid-teens dropping to around 10 °C in the evening.

A series of strong low pressure systems moving through the Canadian Arctic will sustain a westerly flow aloft over the Prairies this week. That will keep western Canada under the influence of milder Pacific air and keep the colder Arctic air locked up in the north.

As a result, Winnipeg will see nothing but seasonably mild conditions ahead with daytime highs in the 10 to 15 °C range and overnight lows hovering near or just above freezing. Skies will be fairly sunny as dry conditions persist across the region, but some cloud cover is possible on tonight into Saturday morning before clearing out. Winds will be a bit breezy out o the southwest today, then calmer conditions will move in for Saturday and Sunday.

Long Range Outlook

The warm weather will stick around into the start of next week, but it will get a bit windier out of the west. For Halloween evening, it still looks like it will be close to 10 °C around trick or treat time and cool off gradually through the evening.

By mid-week, the weather pattern will begin to shift, bringing in cloudier conditions and a return towards seasonal temperatures. Long-range forecasts show the next notable chance for precipitation arriving at the end of next week. What it falls at is anyone’s guess right now, but signs point towards a bit of a wintery mix that could end with a bit of snow finally sticking. Hopefully not, though, and we can keep the snow away for as long as possible!

Today’s seasonal daytime high in Winnipeg is 7 °C while the seasonal overnight low is -3 °C.

Hot Summer Weather Ahead

Brad

The heat will slowly build over Southern Manitoba in the coming days as the region heads towards a very hot weekend.

GDPS 500 mb Height Forecast (with Anomaly) valid 12Z Wednesday July 13, 2022
The forecast 500 mb heights with the climatological anomaly overlaid shows a strong upper ridge building across Manitoba on Tuesday.

This week will see an upper ridge building into and strengthening over the Prairies. As it does, conditions will stabilize as temperatures slowly climb.

Southern Manitoba will see a sunny start to the day give way to mixed skies. Temperatures will climb into the upper 20s across the region with a bit of a northerly breeze. Some lingering instability will result in a few scattered showers that will move through the Red River Valley in the afternoon with the risk of a thundershower. Skies will clear in the evening as temperatures head to a low in the mid-teens.

Wednesday will be a beautiful day across the region with sunshine, light winds out of the south and a high in the upper 20s. Temperatures will fall to a low in the upper teens on Wednesday night.

On Thursday, an upper disturbance lifting northeastwards across the Prairies will bring some cloud to the region along with increasing heat and humidity. Temperatures should climb to the 30 °C mark with breezy southerly winds developing. The humidity will gradually climb through the day, likely beginning to feel a bit muggy by the end of the day. Showers and thunderstorms are likely across the region in the evening, and with the heat and humidity present there could be a risk of severe weather.

Long Range Outlook

The upper ridge will rebound and strengthen heading into the weekend, bringing increasing sun and even warmer weather. Daytime highs will climb into the low to mid-30s for the weekend under sunny skies. The humidity will likely be moderate to high which will help keep overnight lows mild near 20 °C.

The heat will continue into Monday before the upper ridge begins to break down, bringing slightly cooler weather and the chance of rain back to the region.

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

Hot and Humid Summer Weather Comes to Southern Manitoba This Weekend

Brad

The heat will gradually amplify across southern Manitoba over the coming days as a hot and humid air mass builds into the province.

NAM 2m Temperature Forecast valid 21Z Sunday June 19, 2022
Very hot and humid conditions will move into Southern Manitoba by Sunday.

After a couple cool, windy, and showery days across the region, summer weather is quickly rebounding back into southern Manitoba. Driven by an intensifying upper ridge, Winnipeg will see near-seasonal conditions today quickly heat up into the weekend.

It will be a beautiful day in Winnipeg today with temperatures climbing to the mid-20s under sunny skies. Winds won’t be much of an issue, swinging around to the east for the afternoon and picking up to around 20 km/h. Humidity will stay comfortable through the day with dew points around 10 °C. Temperatures will drop into the mid-teens tonight with some cloud moving into the area as a warm front approaches.

Saturday will bring a cloudy start to the day with some showers or thunderstorms possible through the morning into midday. Some sunny breaks will develop in the afternoon as temperatures head to a high in the upper 20s. Winds will strengthen out of the southeast to around 40 km/h with gradually increasing humidity. The dew point will climb into the mid- to upper-teens by the end of the day as the warm air continues to push into the region. Temperatures will stay very warm on Saturday night, only dropping into the low 20s with a gradually diminishing wind.

Sunday will bring dangerous heat to southern Manitoba as the mercury soars and very humid conditions develop. With partly cloudy skies, temperatures on Sunday will climb into the low to mid-30s across most of southern Manitoba. As this happens, dew points will rise rapidly as the day warms up, increasing from the mid-teens up into the 20–25 °C range through the morning. This heat and humidity will produce humidex values of 40–45, making for weather that can be dangerous to be exposed to for extended periods.

In preparation for the heat, ensure that if you have air conditioning its in working order. Limit your exposure to the heat on Sunday, drinking plenty of water and ensuring you can find breaks to cool off whether it be indoors, shade, or other cooling opportunities such as city-run splash pads (great for the kids!). If you know anyone at risk for heat-related illnesses such as elderly individuals, those without air conditioning or access to cool spaces, or some with other forms of chronic illnesses, organize a plan to check in with them or provide some way of cooling off. Be sure to check out more information about preparing for and managing heat-related illnesses.

Sunday night will also stay very warm with overnight lows only dipping into the low 20s. Some showers or thunderstorms are likely on Sunday night, but they will likely avoid the Red River Valley. They should develop well to the west-northwest and likely pose a more notable risk to the Parkland and Interlake regions.

Long Range Outlook

Hot weather will continue on Monday, but it won’t be quite as extreme as seen on Sunday; highs in the low 30s will combine with dew points easing into the upper teens. This will produce humidex values of 35–40, which when combined with the second night of very warm lows may still be an issue for some. Conditions will turn more unsettled for the rest of the week as cooler air brings more seasonal conditions back to the region.

Today’s seasonal daytime high in Winnipeg is 24 °C while the seasonal overnight low is 11 °C.
