Cool front: Noticeably cooler and less humid Friday
A fresher northwest breeze brings a change of air masses
The hottest month of the year in Minnesota is running a fever. It’s been a steamy and stormy first week of July.
The temperature in the Twin Cities and much of southern Minnesota hit 90 degrees four of the first eight days this month. July temperatures are running more than 7 degrees warmer than average so far in the Twin Cities.
Cool front Friday
A cool front finally sweeps our steamy and stormy air mass southward Friday. It’s not the strongest front on the weather maps, but a noticeably drier and cooler air mass oozes south from Canada on Friday’s gentle northwest breeze.
The National Oceanic and Atmospheric Administration’s NAM 3 km resolution model captures the air mass change. Watch as dew points fall from the 70s Thursday midday into the upper 50s by Friday morning. That translates into less than half the water vapor in the air in about 24 hours.
