It's been a cool and wet couple of days over southern Manitoba, but things will be clearing up nicely this week as a stubborn area of low pressure over northern Ontario finally pushes east allowing high pressure to build in from the west. Cloudy skies Tuesday will give way to increasing sunshine by afternoon as the high pressure ridge moves in from Saskatchewan. This will lead to some glorious weather through mid week with plenty of sunshine and temperature in the mid 20s Wednesday and Thursday. The warmer weather will retreat a bit on Friday and Saturday with highs around 20C as we get easterly outflow winds from a cooler high pressure system moving across northern MB into NW Ontario. But things should warm up again by Sunday into next week as we get a return flow of warmer air back into southern MB.
As far as precipitation goes, it looks generally dry through the first week of June with long range guidance showing little in the way of major systems or convection over much of southern MB through the next 7-10 days. There is a risk of some showers and thunderstorms over SW MB Friday, but the risk appears restricted to SW MB into North Dakota. Things are actually getting a bit dry over southern MB, especially over far SW MB which has received only 10-20% of normal rainfall so far this month. Even the RRV has only seen about half the usual rainfall in May (normal May precip is about 55-60 mm) Farmers will be getting increasingly anxious if the dry weather continues for much longer as it will start to affect their newly planted crop.
