Memorial Day Weekend is often referred to as the “Unofficial Start of Summer”. Mother Nature will remind us this weekend that it’s still Spring.
High pressure will slowly move across southern Canada tonight and Friday, resulting in a rather chilly night tonight, but a sunny and seasonably mild day on Friday. As the high moves into Atlantic Canada on Saturday low pressure will move into the Midwest, sending plenty of clouds our way, along with cooler temperatures, thanks to the onshore flow around the high pressure area to our east. Right now, it looks like the high will be strong enough to prevent rainfall ahead of the Midwest storm from getting in here during the day on Saturday, so it will be just a cloudy and cool day. However, that rain will likely move in for Saturday night and Sunday, so if you have any outdoor plans on Sunday, it might be time to look for alternatives. While we’re not expecting heavy rain for most of the region, any rain we get is beneficial, and will help put a dent in the ongoing drought. The rain should taper off Monday morning, with improving conditions in the afternoon as the low pressure area pulls away, so we may salvage a decent day for the holiday.
Thursday night: Gradual clearing. Low 42-49.
