Major Low Brings Mild Weather

Brad Leave a comment

Winnipeg’s temperature will be climbing well above-seasonal through the second half of this week as a major low pressure system develops over the central Prairies, drawing mild air northwards out of the United States. While southern Manitoba will avoid the brunt of this system, it will also bring some gusty winds and a good chance of rain to round out the work week.

Today will be a very pleasant day in Winnipeg as a ridge of high pressure brings mainly sunny skies to the region and temperatures climb to a high near 15°C. Winds will be light out of the east to northeast, making for a wonderful day to get outside. Temperatures will dip down to a low near +1°C under partly cloudy skies overnight.

Thursday will bring even warmer temperatures to the region with highs climbing into the upper teens under partly cloudy skies. A major low pressure system will be organizing over the western Prairies, which will begin to increase winds out of the south over Manitoba. In Winnipeg & the Red River Valley, expect winds to pick up out of the southeast to 20-30 km/h by the end of the day. Temperatures will dip to a low near 8°C on Thursday night under partly cloudy skies. Winds will continue to increase through the night, reaching 30 to 40 km/h by Friday morning.

Much of Manitoba will see precipitation on Saturday with rain in the south changing to significant snow over the north.

Friday will be an active day as the low pressure system heads across the central Prairies and its cold front pushes eastwards across the Red River Valley. Ahead of the front, temperatures will be mild with highs reaching the mid- to upper-teens, but the winds will be quite strong out of the south at around 40 gusting 60 km/h. Cloud will increase through the day as the cold front approaches.

The cold front will push into the Red River Valley in the afternoon, supporting a developing area of showers as it does so. Indications at this point are that the showers could be fairly heavy with a slight chance of some thunderstorms embedded within.

Once the front passes through, winds will die down and skies will clear as temperatures head to a low near 5°C.

Long Range

The weekend looks to be a bit of a mixed bag. Saturday will be pleasant with near-seasonal temperatures and partly cloudy skies. Winds will be out of the west-northwest to around 20 km/h.

Things change on Saturday night as a second cold front moves through the region, ushering in Arctic air that will send temperatures well below seasonal and bring a chance of flurries back to the region.

Once the cold front moves through on Friday evening, cooler air will be ushered into the region throughout Saturday, followed by a second cold front on Saturday night.

Sunday will likely have mainly cloudy skies as temperatures drop to around 0°C midday and remain there. Sunday night will be seasonably cool as skies clear out and temperatures dip to a low in the -3 to -5°C range.

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

Warmer-than-Normal Temperatures Continue, But With Windy Conditions

Temperatures in Winnipeg will climb into the upper teens over the next couple days before dropping back towards seasonal values on Sunday. The wind will put a bit of a hamper on enjoyment, though, as both today and Sunday will feature fairly prominent winds.

A surge of warmth is on the way to Winnipeg. The warm air will be drawn northwards by a developing low pressure system over Saskatchewan that will track eastwards through the Interlake on Saturday.

But first, today will be mild with a high temperature near 16°C coming in well above the seasonal average of 7°C. Skies will be a bit mixed as a combination of mid- and upper-level cloud moves through the Red River Valley. That said, the most prominent feature will be the southerly winds that pick up later this morning and strengthen to 40-50 km/h for the afternoon. The winds will then taper off fairly quickly in the evening as temperatures head to a low near 7°C under partly cloudy skies.

Saturday will be a nicer, albeit slightly cloudier day, than Friday. Temperatures will climb to a high near 17°C with much lighter southerly winds shifting to westerly in the afternoon. It looks like it will be a fairly cloudy day, but not completely without some sunshine. If there manages to be a little more sunshine than expected, it’s possible that the daytime high could reach up to 18 or 19°C. Rain-wise, there only appears to be a very slight chance of some showers in the afternoon, but it seems pretty insubstantial at this point.

While a slight chance of showers exists over the Red River Valley on Saturday, by a vast majority of the precipitation associated with the system will fall across northern Manitoba.

Once the sun goes down, Winnipeg will be headed towards an overnight low near 3°C as the winds shift to northerly under partly cloudy to mixed skies.

Sunday will bring increasing cloudiness to Winnipeg as gusty northerly winds increase to around 30 km/h. Temperatures will be much cooler with a seasonal high near 8°C. Temperatures will dip down to around -3°C on Sunday night with mixed skies.

Long Range

As mentioned in the beginning, it had appeared that there would be a chance for a series of low pressure systems to impact the region beginning Sunday night and bring a mix of rain and snow to the region. Fortunately for us, that no longer appears to be the case as widespread support has emerged that places this system well to our south in South Dakota, the southern portions of North Dakota, and into Minnesota. This leaves us with just breezy northerly winds and cooling temperatures.

Much of next week looks to bring seasonal to slightly above-seasonal temperatures to the region, with dry conditions through the first half of the week and more organized chances for rainfall into the latter half of the week.

Winnipeg’s seasonal daytime high is currently 7°C while the seasonal overnight low is -4°C.

Variable Cloudiness with Above-Normal Temperatures

The weekend will bring a mixed bag to Winnipeg with temperatures climbing into above-seasonal values, but a fair amount of cloud will remain in place over the next few days, dampening the spring-like feeling.

Cooler temperatures will be in place over the Red River Valley today as a result of northerly winds to 20-30 km/h that moved in behind a cold frontal passage overnight. Temperatures are expected to reach high near +2°C in Winnipeg today as those winds diminish by midday. Skies will become a mix in the morning and remain that way through much of the remainder of the day.

Skies should clear up tonight as temperatures drop to a low near -5°C.

Milder temperatures are expected across southern Manitoba on Saturday.

Saturday will bring slightly milder temperatures to the region, but alongside the warmth will come breezy southerly winds to around 30 gusting 50 km/h. Temperatures will climb to a high near 4 or 5°C with skies clouding over. Saturday night will bring diminishing winds, cloudy skies and a seasonally mild overnight low near 0°C.

Sunday will be similar temperature-wise to Saturday with a high temperature near 5°C, but a trough of low pressure moving into the Red River Valley will bring lighter winds and the chance for some rain showers. Skies will clear a bit overnight as temperatures head to a low near 0°C once again.

Long Range

As mentioned in our last post, the forecast for a continued trend of gradual warming continues. Little has changed from our outlook earlier in the week, with above-normal temperatures expected in most places over the coming couple weeks.

Winnipeg’s seasonal daytime high is currently 2°C while the seasonal overnight low is -8°C.

A Windy Return to Milder Temperatures

Brad Leave a comment

The wind will be back today, but this time rather than slamming colder temperatures southwards through the Red River Valley, it will be gradually bringing warmer weather back to the region. A generally warm and dry pattern will establish itself for the coming week or so, likely bringing a gradual spring melt to the Red River Valley.

As warmer weather once again moves into the Red River Valley today, like clockwork those southerly winds will ramp up and become the main weather feature of the day. The winds will increase through the morning to 30-40 km/h by midday, and then further strengthen in the afternoon to 40 gusting 60 km/h.1 These strong winds will likely persist much of the night before dropping off on Thursday morning. While all this happens, Winnipeg & the Red River Valley will see a sunny morning give way to cloudy skies midday into the early afternoon as temperatures climb to a high near -1°C late in the day.

A deep southerly flow extending from southern Manitoba all the way to Texas will develop by Friday evening.

The cloudy skies will continue overnight with a slight chance of some light snow2 as a warm front associated with a low pressure system passing across the central Prairies moves through. Temperatures will remain steady near -2°C.

Thursday will bring the spring warmth as we enter the warm sector of the system passing by to the north. Temperatures will climb above normal for much of the Red River Valley with high temperatures the +5 to +7°C range. The winds will ease off in the morning and we’ll be left with mixed to cloudy skies. A weak cold front will slump through late in the day, but have little effect on temperatures overall; Thursday night will see a low of just -3°C or so under fairly cloudy skies.

Friday will see temperatures return to near-seasonal values with a high near +2°C under partly cloudy to mixed skies. The lack of any notable winds will make it a pleasant day. Lows will drop to around -3°C on Friday night.

Long Range

The long range forecast is definitely pointing towards the arrival of spring not just for southern Manitoba, but a vast amount of North America. A stable long-wave pattern will be developing over the southern Prairies for the coming 1-2 weeks, bringing relatively dry conditions and ample warm air.

CPC 6-10 Day Temperature Anomaly Forecast — Valid March 27-31, 2017

Daytime highs will climb into the mid- to upper-single digits this weekend and remain there for much, if not all, of the coming week. Throughout this period, it looks like the potential for rain across the Red River Valley is fairly low. Some models hint at a chance for some light rain or snow on Sunday night, but otherwise keep things fairly dry.

NAEFS 8-14 Day Temperature Anomaly Forecast — Valid March 28 to April 4, 2017

Overall, even into the Week 2 timeframe, temperatures look to remain above normal…nearly everywhere. It’s practically a certainty that we’ll be seeing the elimination of the snowpack across the Red River Valley in the coming days, and a substantial melting, if not elimination, of the substantial snowpack over southwestern Manitoba and southeastern Saskatchewan that was produced by the major blizzard last week.

All is not fun and games, though, as the melt, particularly in drainage channels to the Assiniboine river, will transition the region towards dealing with flooding concerns. Fortunately, much of the snowpack has already been eliminated in the North Dakota Red River Valley, which will help ease things slightly. Spring flood forecasts are the responsibility of the Manitoba Government. News and updates can be found here.

Winnipeg’s seasonal daytime high is currently 1°C while the seasonal overnight low is -9°C.
