Major cooldown for Friday and Saturday.. Snow possible for western MB Thursday night? Frost possible Saturday morning over RRV.
Enjoy the 20C temperatures today.. because it will likely be a while before we see temperatures that high again over most of southern MB. A low pressure system crossing southern Manitoba on Thursday will drag a cold front across the regions later Thursday into Thursday evening, ushering in a much cooler airmass from the north. Showers behind the front Thursday evening may even mix with or change to.. (yikes!) snow.. over higher elevations of western MB Thursday night into early Friday. Friday will be an unseasonably cool day across southern MB with mainly cloudy skies and temperatures only around 10C for daytime highs.. over 10C below normal for late May. Skies are expected to partially clear Friday night, which will bring the potential for frost across much of southern MB including Winnipeg by early Saturday morning. Gardeners beware. Saturday should be dry for the most part, but another major system moving out of the American south will push a warm front into the Dakotas, triggering another round of showers and thunderstorms Saturday night into Sunday over southern MB, with the potential for locally heavy rainfall yet again. Generally dry but cool weather is expected into the first part of next week before a warming trend later in the week.
