Southern Manitoba will continue to see unsettled weather through the weekend with system after system tracking through our region. Despite this, temperatures will remain above normal, contiuning this month’s summer-like trend.
We’ll start off with clear skies this morning with patchy fog through the Red River Valley which will burn off by mid-to-late morning as that late-March sun gets to work. We’ll see our temperature get up to 12 or 13°C before skies cloud over mid-to-late afternoon. Most areas in the Red River Valley, including Winnipeg, will then have a chance of seeing some showers as a weak warm front pushes eastwards through the area.
Overnight, much of the Red River Valley has a decent chance to see rain as the mid-levels destabilize with an injection of cold air at 700mb associated with a shortwave tracking through Central Manitoba. Positioning of the shortwave will be crucial to where the precipitation falls, but current indications are that an area of rain will blossom overnight near Brandon and travel east, with lighter showers south of the Trans-Canada Highway and 4-8mm of rain along and north of the TCH.
That rain will clear out by midday Saturday, and the Red River Valley will be left with just a few clouds and beautiful temperatures around 15°C.
It was not mean to last, however, as yet another low begins it’s trek into the Prairies. Winnipeg will get to 11 or 12°C before more clouds push in by mid-afternoon. Light rain will push into the Red River Valley overnight Sunday and then intensify Monday morning, dropping another 5-10mm of rain before it pulls out on Monday evening.
All of these systems are sensitive to exact tracks of subtle features, so we’ll be sure to provide updates in the comments as the weekend progresses. In short, for much of the Red River Valley, the next few days will be unsettled with pleasant temperatures in the low-to-mid teens when the sun manages to poke out and showers/rain every 24-36 hours.
