Near-Seasonal Temperatures Return for the Weekend

Brad Leave a comment

Cooler temperatures have moved into Southern Manitoba behind a low pressure system that brought a few showers and strong northerly winds as it moved across the Red River Valley yesterday evening. Today will be a cool, dreary return to chilly fall weather, but a gradual moderation of temperatures is in store for the remainder of the weekend.

Friday
7°C / 0°C
Cloudy; chance of drizzle or showers

Saturday
10°C / 6°C
Mainly cloudy

Sunday
14°C / 3°C
Mainly sunny

A less-than-pleasant day is in store for Winnipeg today as breezy northerly winds around 30km/h continue to push a cool air mass southwards into the Red River Valley, leaving us with a dreary day with a high barely above where it starts the day off at. The temperature will struggle to climb to 7 or 8°C today under cloudy skies alongside a slight chance of drizzle or shower activity. Skies will remain mainly cloudy tonight with a chance of a few clear breaks late overnight; the temperature will drop to between 0–2°C for the overnight low.

There isn’t too much to say about the weekend other than conditions will gradually improve. Saturday looks fairly cloudy with a high near 10°C and light winds. A partly cloudy night will see the temperature dropping to 6°C or so. Sunday will be quite a pleasant day with temperatures climbing back above normal under mainly sunny skies. Expect a high near 14–15°C and an overnight low on Sunday night near 3°C. At this point, it does look like a low pressure system will move through the Interlake on Sunday, bringing some showers along with it. Current indications are that all of that activity will remain to the north and east of Winnipeg, but we’ll keep an eye on it as the system develops.

Heading into next week looks very nice with temperatures returning to the upper teens as another upper-level ridge builds into the Prairies, spreading mild Pacific air eastwards once again.

Summery Weather Continues

More summery weather is in store this week, just what you were hoping for I’m sure!

Monday will be a pleasant day in southern Manitoba

Today will be a pleasant and uneventful day weather-wise. Temperatures will be in the mid twenties with a light northerly wind and mainly sunny skies. You can thank the surface high pressure system over top of us for the nice day.

28°C / 16°C

Tuesday will be another nice day in southern Manitoba. Temperatures should once again climb into the upper twenties with a light northerly wind and mainly sunny skies. There may be a few pop-up showers or thunderstorms in the afternoon and evening, but they will be highly localized. The most favoured area for one of these storms is in the Interlake.

Wednesday

Wednesday
28°C / 18°C
Mainly Sunny

Wednesday will be fairly similar to Tuesday, with temperatures in the upper twenties and mainly sunny skies. The wind will veer to easterly, but won’t be too strong. No precipitation is expected during the day on Wednesday.

Long Range

The long range forecast is looking pretty good. Some models continue to hint at a cool-down sometime in mid to late August, but there are no indications that cooler weather is imminent. In the mean time, normal to above normal weather should continue, which means high temperatures in the mid to upper twenties.

Warm Weather Continues

The warm, dry weather that has dominated over the past week will continue through the remainder of this week as an area of high pressure continues to stake its claim over the Red River Valley.

Wednesday
27°C / 17°C
Mostly cloudy

Thursday
28°C / 17°C
Mixed skies with slight chance of isolated showers

Friday
27°C / 15°C
Mainly sunny

Today will bring a fair amount of cloud, but it appears that any precipitation will likely remain west of the Red River Valley in Southwestern Manitoba northwards into the Parkland region. There will likely be a small chance of some isolated showers through the Red River Valley, but the odds look slim and even if there were, the total rainfall amounts would be minimal.

While the dry weather is generally appreciated given the wet spring and start to summer, some rainfall would be welcome in the Red River Valley. Winnipeg’s July ended as the 14th driest on record while, in general, the southwestern Red River Valley has now fallen to between 75–90% the normal accumulated precipitation for the growing season. For crops that are near harvest, the dry weather has been welcome, but some crops will be beginning to undergo some stress due to the lack of rainfall. Unfortunately, no significant rains are in the forecast in the coming week.

Percentages of the normal seasonal accumulated precipitation show below-normal rainfall developing in the southwestern Red River Valley.

Cloud and precipitation aside, today will be pleasant. Daytime highs will sit in the upper 20s with light winds. There’s significant disagreement as to what will happen overnight, though, as some models produce no precipitation whatsoever – which is what I’m leaning towards – while others develop an area of showers in the evening and move it through the Red River Valley.

While the possibility certainly exists for some rain tomorrow night, or even an isolated thunderstorm, it’s most likely that the weather will remain dry in the Red River Valley. We’ll be sure to provide an update in the comments below as things become more clear later today. The temperature will drop into the upper teens overnight.

Thursday & Friday

Warm temperatures will continue Thursday with daytime highs once again in the upper 20s. Skies will be mixed with an outside chance of isolated showers in Winnipeg & the Red River Valley. Winds will continue to be light.

Partly cloudy skies with a slight chance for isolated shower activity returns Thursday night as temperatures dip into the upper teens.

Friday will bring partly cloudy skies with a high once again in the mid-to-upper 20’s. Friday night will bring partly cloudy skies with a low in the mid-teens.

Weekend Look-Ahead

The GDPS is forecasting some rainfall on Saturday night as a weak cold front sweeps through the region.

Summer weather continues right through the weekend with plenty of sunshine on Saturday and Sunday with daytime highs in the upper 20’s. A cold front will advance through the Red River Valley late Saturday afternoon through the evening and bring a chance for thunderstorms to the region, otherwise the weekend into the start of next week looks dry.

August off to a Splendid Start

With July in the books, August looks to continue our streak of beautiful weather as an upper-level ridge continues to produce stable, warm and mostly dry weather over Southern Manitoba.

Friday
29°C / 16°C
Sunny with increasing afternoon cloud

Saturday
27°C / 13°C
Mixed skies with a chance of isolated showers

Sunday
26°C / 12°C
Mainly sunny with some afternoon cloud

It won’t take a lot of words to describe the weather over the next few days. Today will bring another sunny day that will most likely be the warmest so far this week with a high temperature approaching the 30°C mark. Clouds will roll in later in the afternoon ahead of a disturbance trundling down from the northwest Red River Valley overnight.

Tonight’s low temperature will bottom out near 15 or 16°C under partly cloudy skies. There could potentially be a few isolated showers through the Red River Valley through the overnight period, but the odds are definitely stacked against it happening.

Saturday looks like a pleasant day with mixed skies and a slight chance of showers in the afternoon through the overnight period again as a weak trough pushes through the region. Temperatures will climb into the mid–20’s for the daytime high and drop down towards low teens overnight.

Sunday will be another seasonal day with highs in the mid 20’s and overnight lows in the low teens. The day will be fairly sunny with some increasing afternoon cloud as a weak system slumps through southwestern Manitoba, bringing some shower activity to that area. Here in the Red River Valley we’ll likely remain dry, although at this point it looks like late in the day some shower activity may edge into the western Red River Valley.

None of the activity over the next few days is expected to be significant and the long-range outlook continues our seasonably warm and dry weather through much of the coming week.
