Weekend Outlook: March 26-29, 2021

We can often get some wild swings in weather in late March, and while this weekend’s won’t be that dramatic, we do have some big changes coming.

As skies clear out this afternoon, temperatures will jump into the upper 60s and 70s. Loop provided by the College of DuPage.

Unseasonably warm conditions will remain in place this afternoon into Friday as low pressure heads toward the Great Lakes. This is the same system responsible for all of the severe weather down South today. We’ll stay warm ahead of the system into early Friday before some rain moves in. With mild air in place, don’t be surprised if we have a rumble of thunder with the shower activity Friday morning. A cold front will be moving toward the region during the day, and ahead of it, temperatures could get close to 70 again, if we can get any sunshine.

That front will move through late in the day, possibly with some more showers or thunderstorms. Behind it, gusty winds will usher cooler air into the region. While this shouldn’t be as potent as the last couple of wind events we’ve had, it could be enough to take down a few trees or power lines. High pressure then builds in for Saturday with sunshine and more seasonable temperatures. By Sunday, another system quickly moves in, with rain likely. Since it’s been a dry month, we really need the rain, even though it’ll make for a rather damp Sunday. Rain ends Sunday night as the system drags a cold front across the region, then high pressure returns on Monday with sunshine and much cooler conditions.
