An Unsettled Sunday, Otherwise Pleasant

Brad Leave a comment

Fairly pleasant weather will be on tap for next couple days until an upper trough swings through the area on Sunday, bringing a risk of showers or thunderstorms to the Red River Valley.

Pleasant Weather Ahead

Pleasant weather is on tap for Winnipeg.

Through the next couple days, mainly sunny skies and warm temperatures will be the dominant weather across the Red River Valley. High temperatures today and tomorrow will climb up to around 29°C, while sunny skies dominate today and we move into more of a mix of sun and cloud tomorrow.

On Sunday, an upper trough begins to work it’s way into Southern Manitoba. It’s very difficult to say what exactly is going to happen with this system as it moves through. It seems clear that there will be two main areas of precipitation:

  1. An area of rain that moves through the Interlake.
  2. An area of showers and/or thunderstorms that develops over North Dakota and slides southeastwards.

As for what happens over the Red River Valley; it’s tough to say. Guidance currently suggests that there’s a moderate chance of rain for us. Should we see precipitation, it’s likely that we’d see a batch of morning showers then a little bit of sunshine before some afternoon convection bubbles up over the Red River Valley. There would be a risk of non-severe thunderstorms if that scenario happens. This system seems to be quite sensitive, so we’ll be sure to post updates in the comments below. The daytime high on Sunday will end up being somewhere between 24°C to 27°C depending on how much sun or rain we see.

Sunny skies return to start next week before another system brings a chance of rain mid-week.

Pleasant Start to the Weekend

Brad Leave a comment

After a few days that threatened storms for the Red River Valley, we’re heading out the other side with most communities seeing little to no rain. Steinbach is a notable exception, with over 100mm of rain falling1 through a rather unusual rainfall event early Wednesday morning which produced significant overland flooding2.

24hr. Precipitation Totals valid Sunday Evening

24 hour accumulated precipitation from Friday Saturday evening to Sunday evening.

A pleasant start to the weekend is ahead, with no chance of showers until Saturday evening and overnight. Today we’ll see mainly sunny skies as our temperatures rebound from yesterday’s system up to a high near 26°C. The overnight low tonight will be around 15°C. Warmer air pushing in aloft will allow temperatures to climb higher on Saturday and Sunday, with daytime highs close to 30°C expected. Humidity will remain relatively low for Saturday, however things may get a little uncomfortable on Sunday as dewpoints begin to climb closer to the 20°C mark.

On Saturday a disturbance entering the province will generate some showers and thunderstorms over SW Manitoba through the late morning and afternoon hours. The (thunder)showers will spread eastwards through the evening and overnight, however it’s currently looking like the bulk of precipitation will occur through the Interlake. The northern half of the Red River Valley looks to have a decent chance of seeing some sort of precipitation, however the odds look very slim that the southern half will see anything.

We’ll see increasing cloud Sunday afternoon as the back side of this system prepares to swing through Sunday night. As it does, there will again be a chance of showers for Winnipeg and, as it looks now, the eastern RRV. We’ll be sure to provide updates in the comments as this system approaches.

Warm Weather Continues; Little Rain in Sight

Upper-level flow for this evening

Upper-level flow forecast for this evening over Central North America from the GEM-GLB. Of note is the shortwave pushing out of Alberta. This feature will flatten the upper ridge over Southern Manitoba and bring some unsettled weather to SW MB on Sunday.

Rainfall will continue to be spotty and elusive over the Red River Valley as warm temperatures persist and and upper-level ridging maintains it’s hold over the Eastern Prairies. While numerous systems trek through Alberta and Saskatchewan into Northern Manitoba over the next few days, mainly sunny skies are in store for us as we head into the weekend with daytime highs generally around 28°C across much of the Red River Valley. Humidity levels will be lower today and through the weekend than they were on Thursday, however overnight lows will still remain relatively warm in the high teens.

On Sunday, a low pressure system will move eastwards out of Saskatchewan through the Interlake region. Models are suggesting that a band of nocturnal thunderstorms will push into Southern Manitoba on Saturday night and push eastwards before dying around mid-morning. It’s far too early to know where these storms will actually occur, so we’ll be sure to provide updates in the comments. After that band of thunderstorms falls apart, the rest of Sunday actually looks quite nice with clearing skies in the RRV and a high near 30°C.

Next week looks to start off quite pleasant with little chance of precipitation in the RRV until mid-week.

Hot Weekend Ahead

Hot weather will continue through the Red River Valley this weekend, but unsettled weather will return at weekend’s end as an upper trough swings across the Prairies.

850mb Temperatures from the NAM for Friday Afternoon

850mb temperatures from the NAM for Friday afternoon. While temperatures have cooled since Wednesday, very warm air is still in place over Southern Manitoba.

We’ll see quite a nice day today with plenty of sunshine and a high near 31°C. Winds will light out of the west-northwest across most of the Red River Valley. We’ll see a warm night tonight with an overnight low of just 19°C.

For Saturday, we’ll see another sunny day with highs in the low 30’s across the Red River Valley. Some thunderstorms are possible over portions of southwest Manitoba, including Melita, Virden, Brandon, and the Pilot Mound areas. Some communities very close to the western escarpment of the RRV may also have a slight chance at seeing a thundershower.

Clouds will begin to roll in Sunday morning as a upper trough begins pushing into our region. It’s too early to tell who will get what for precipitation, other than it looks like there might be a slight chance of showers for the Southern Red River Valley on Sunday afternoon before the main system pushes through on Sunday night into Monday morning. Precipitation distribution is still questionable with this system, but amounts generally look light with less than 5mm for areas that see rain. We’ll narrow down the expected areas to see rain as we get a little bit closer to this system’s arrival. The cloud cover will limit our high temperatures to the mid-to-upper 20’s and the wind will be out of the southeast at 15 to 30km/h.
