Here Comes Cooler Air

Summer is trying it’s best to stick around. Speaking of sticky, we hit a high of at least 80 in Duluth today, with dewpoints still in the 60s. Yes, still muggy. You wear the air like it’s a wet shirt. I don’t like it. But, that’s going to change before we all go to sleep tonight. Right now, there is a fairly strong cold front moving from west to east across Minnesota. Behind that front is an airmass from Canada (no smoke this time), that is much cooler and less humid than what we currently have. We will all notice a significant difference later tonight, and especially tomorrow. Strong NW winds will push us around all weekend, gusting to 25mph, with air that is dry and refreshing. You might even think it feels like a touch of fall! A few showers may occur with the passage of the cold front, but most of us will not see rain as the front moves through the area.

The weekend will be mostly sunny, dry, cool, and breezy. Saturday’s high will only hit about 66, with Sunday’s high a cool 62. With those strong NW winds, there will be a little bit of a wind chill! By Tuesday morning, there could even be some light frost, away from Lake Superior, like in the lower elevations of parts of the Iron Range. We are getting into the last 9 days of August, and days are getting shorter, quickly.

Our highs will get back into the 70s by Tuesday and Wednesday, and a warm front heading this way will push us up to near 80 by next Friday. So, if you love summer (don’t we all?), don’t lose faith. The first day of Astronomical Autumn isn’t til September 21st. We still have some summery warmth ahead!

Have a great (cool) weekend!
