Unsettled Weather Continues

More unsettled weather is on the way as another generally unstable day gives way to the passage of a low pressure system and associated cold front that will finally result in a shift in the larger-scale weather pattern.

Generally unsettled weather will be in place over Southern Manitoba today as an unstable air mass continues to preside over the region. Shower activity will likely continue to remain elusive here in Winnipeg, but elsewhere, particularly northwards into the Interlake may see a few showers or thundershowers today. It will be hot with high temperatures near 30° combining with dewpoint values near 20°C making it feel more like the upper 30’s. Temperatures will dip just below the 20°C mark overnight under mainly clear skies.

Saturday will be another hot and humid day with plenty of sunshine. Increasing cloud in the afternoon ahead of an advancing cold front will restrain the daytime high to a couple degrees cooler than today. Winds will be the strongest they’ve been in a while, strengthening to 30-40km/h out of the south by late in the afternoon.

A line of showers and thunderstorms will develop along a cold front stretching from the northern Interlake into southwestern Manitoba late in the day and gradually push eastwards through the evening. It’s very likely that most places in the Red River Valley, Winnipeg included, will see some shower or thunderstorm activity as the front passes through. Rainfall amounts will be quite variable; it looks like 5 to 15mm will be fairly common, however higher amounts will be possible in thunderstorms. Skies will clear behind the cold front with temperatures dropping to the mid-teens.

Sunday will be a beautiful, albeit cooler, day. Southern Manitoba will see just a few clouds and a high near 24 or 25°C. Much of the humidity will be flushed out by the cold front, so it should also be a much more comfortable feeling day as well. There may be a slight chance of some isolated shower activity on Sunday night as a weak disturbance ripples southeastwards across the province. Temperatures will drop into the low teens on Sunday night.
