We are a few days into meteorological autumn, and with that starts to come the threat of frost and freeze conditions across the state. While the average first 32 degree morning in the Twin Cities isn't until early October, the earliest on record occurred on September 3, 1974. Many locations across Minnesota dropped into the 20s and 30s for lows that morning, with a low of 22 in both Pipestone and Tower.
While there is no threat of frost in the Twin Cities this week, we will have to watch the potential for some frosty mornings Up North. A cold front has moved through, meaning highs will be a touch cooler for your Labor Day activities with the chance of a few pop-up afternoon showers. Much cooler air filters in from Canada Tuesday and Wednesday, with highs in the 60s and lows in the 40s and 50s in the Twin Cities. However, some areas across northern Minnesota could drop into the 30s, leading to the threat of frost.
The good news is that warmer weather returns for the second half of the week. Enjoy your Labor Day!
