Happy Saturday, and first day of Winter everyone! We started the day off with some sunshine and MUCH COLDER temperatures than anticipated, with lows bottoming out around -7F last night in Rochester. Less cloud cover and the fresh snow allowed for optimal radiational cooling at the surface, resulting in colder than expected temperatures across most of Minnesota. Temperatures have warmed into the mid to upper teens in Minnesota and lower 20F’s for most of northern Iowa this afternoon.
Temperatures will not cool down much tonight, thanks to increasingly breezy southerly winds, and cloud cover through around midnight. Looking at lows in the mid teens for most locations, with decreasing clouds through the night.
Sunday will be much warmer, with highs in the low to mid 30F’s, under a partly to mostly cloudy sky. Winds will be quite breezy out of the south, gusting up to 30 mph at times during the afternoon. Not a bad late December day by any standards!…
