While we're only a few days removed from the month of August, it's been feeling more like winter for some! Residents in locations across North Dakota, Montana, Wyoming, and Colorado woke up to temperatures in the mid-20s earlier Saturday morning (see above)!
While the cooler airmass remains in place, temperatures are expected to drop quickly again into the early morning hours of Sunday. New alerts have been issued, with Frost Advisories covering much of the Dakotas, and a few counties in northern Minnesota under a Freeze Warning.
While temperatures have bottomed out under clear skies at night, sunshine during the day has been modifying the cold airmass. As it is still early September, the sun angle remains quite high in the sky! Directly behind the front, however, is a different story, with temperatures nearly 20° cooler on Saturday afternoon compared to 24 hours prior.
For the latter half of the weekend, the cold front will bring temperatures down across the Northeast. Where the front has not cleared, temperatures will push back into the 90s.
