Cloudy, But Mild

This week will start out on the grey side, with more clouds than sun on most days. However, temperatures will remain mild with values at or above seasonal norms.

Mild but cloudy conditions are expected in southern Manitoba today.

This Week

Today will be a fairly typical late October day in southern Manitoba. Skies will remain mainly cloudy in most areas as a low cloud deck remains suck along the eastern edge of a surface ridge. Temperatures will be near seasonal values, with highs in the mid to upper single digits. Winds will be light from the east. There is a slight chance of a shower or flurry, but not significant accumulations are expected.

Tuesday will see temperatures warm slightly over today, but skies will remain grey. An approaching system will ensure continued cloudiness over southern Manitoba, but a stiff southeasterly flow will allow temperatures to climb up near 10C in most areas. That southeasterly flow will be gusting up to 50 km/h by the afternoon, making these slightly-above seasonal temperatures seem a bit chilly. Shower activity is possible during the day, with a better chance of rain Tuesday night into Wednesday as that system moves closer.

Wednesday will remain mainly cloudy with a continued chance of showers as a weak low pressure system slowly passes by. Temperatures will remain mild, near 10C, with gusty south winds of 20-30 km/h.

Long Range

Long range models show generally seasonal to above-seasonal temperatures as we move through the end of October. Our normal high for this time of year is 7C, suggesting that temperatures in the upper single digits or low double digits will be most common through month’s end. These warm conditions will likely spill into early November, but it remains to be seen whether or not November will see an early start to winter, or if we’ll have to wait a bit longer for the white stuff to come for good.

Cloudy & Cool Days Ahead

Winnipeg will be stuck in a fairly cloudy and cool second half to the work week as a broad upper-level trough remains entrenched over the region.

Cool & Relatively Dreary

While this morning may bring a few smiles with some sunshine, more cloud will quickly be moving back into Winnipeg, turning skies grey and leaving cool, fall-like weather in the wake. By early this afternoon, skies should be completely clouded up once again with temperatures topping out near 6°C. Winds will be out of the west-northwest at around 20-25 km/h with some gusts in the 30-40 km/h range.

Skies will remain fairly cloudy overnight with northwesterly winds continuing and temperatures dipping down to around 1°C.

Thursday morning will bring more cloudy skies with a slight chance of some shower or flurry activity as a weak band of lake-effect precipitation moves off of Lake Manitoba. It should dissipate by midday, and we’ll be left with cloudy skies that gradually begin to break up late in the afternoon, calm winds, and a high near 7°C.

Thursday night will bring a low once again near 1°C under partly cloudy skies.

Showers Possible Friday

A warm front moving across the Prairies on Friday will bring the chance of showers to the region alongside a shift to a warmer weather pattern.

A warm front will push eastwards across the Red River Valley on Friday.

By midday the chance for showers move into Winnipeg with winds picking up out of the south to 30-40 km/h. It doesn’t look like rainfall totals will be much to speak of (less than 2mm), but there may be just enough to make the ground wet.

The warmest air will remain to our south, however, so daytime highs will sit near 9°C. Friday night will bring a low near 2°C under partly cloudy skies.

Long Range

The weekend is looking slightly warmer with highs near 10°C and overnight lows continuing in the 1-2°C range. Skies will likely be mixed through the weekend and there may be another chance for some light shower activity on Saturday afternoon.

Winnipeg’s seasonal daytime high is currently 9°C while the seasonal overnight low is -2°C.

Cool Weather Starts The Week

This week will remain on the cool side as we continue to deal with chilly air flooding down from the north.

This Week

Today will be another cool one in southern Manitoba. High temperatures in the upper single digits are expected with breezy north winds. A weak low pressure system will pass through the region, perhaps bringing a few showers to southern Manitoba. Portions of western Manitoba and the Interlake may receive some heavier precipitation, with periods of light to moderate rain possible. There may even be some snow mixed in, especially as temperatures cool in the evening and after dark.

Tuesday will remain cool, with temperatures once again in the mid to upper single digits across southern Manitoba. Skies will be mainly cloudy with a slight chance of a shower or flurry. Winds will be breezy out of the north at 20 km/h.

Cool weather will continue on Wednesday as high temperatures only climb into the mid single digits. Skies will remain mainly cloudy with a slight chance of showers or flurries. Winds will be westerly at 20 km/h.

Long Range

Medium- to long-range models suggest that above-normal weather may make a come back as we move toward mid-month with temperatures that may begin to climb back to normal or above-normal values by the weekend and continue into next week. This should stave off the risk of any significant snow for the foreseeable future.

Chilly Weekend Ahead

Cool, unsettled weather will dominate the weather for much of the coming few days as a northwesterly flow of Arctic air puts a damper on the weekend.

The chill northwesterly flow will be in place for today and tomorrow, keeping temperatures well below normal and spreading plenty of clouds across the region and bringing several chances for showers or flurries. High temperatures will sit near 6°C and 8°C tomorrow, with overnight lows near 1°C both tonight and tomorrow night. Winds will be breezy today out of the west at around 30 gusting to 50 km/h and lighter on Saturday.

A smattering of showers and flurries are expected across Southern Manitoba today.

Today will bring widespread showers or flurries to Winnipeg & area today, with enhancement in the lee of the lakes leading to isolated bands of heavier precipitation. The unsettled weather will diminish overnight until all that’s left into Saturday morning is some streamer activity off of both Lake Manitoba and Lake Winnipeg. There’s a slight chance that the lake-effect activity will clip through Winnipeg Saturday morning, but otherwise it should be cloudy & fairly dry.

A new disturbance will move into the region on Sunday, shifting winds out of the south and spreading some light rain across much of Southern Manitoba. Temperatures will climb a bit higher than they’ve been lately with a high near 11°C, but winds will be a bit breezy out of the south.

Long Range

Cooler weather will persist into the start of next week, but hope is on the horizon.

Models are all very consistent in building a fairly substantial upper ridge into the United States, bringing slightly above-normal temperatures for next week and fewer chances for precipitation.
