Weather Synopsis
A cold and mostly cloudy day (Few peeks of sun) with highs today generally in the mid 30s with several locations in the Northland having their coldest high temp or a top 5 coldest high temp on record for October 14.
There was an area of light snow or rain that affected much of northwest Wisconsin back into eastern and northeast Minnesota this afternoon due to a band of F-GEN that setup today across parts of the upper Midwest, this band was strongest farther south which helped to produce a swath of accumulating snowfall of a half inch to over 4 inches today in parts of south-central Minnesota into west-central Wisconsin.
RAP model analysis this afternoon had a strong shortwave trough digging S/E through the northern Plains with a southwest flow aloft in place across the upper Midwest out ahead of that aforementioned trough. A cold airmass covers our area today with 850mb temperatures of -8 to -10C!
Forecast for northeast Minnesota and northwest Wisconsin
[Tonight]
Scattered snow showers and flurries will continue under a considerable amount of cloud cover. There is a chance that a few narrow bands of heavier snow showers setup later tonight-early Monday morning over parts of north-central and east-central Minnesota as a strong trough/upper low approaches from the NW, these bands will be quite localized, however, but could drop anywhere from 0.5 to around 2.0 inches of snow by dawn in a few spots, but most of us shouldn’t see any accumulating snow tonight. Lows will range from around 20 to 30 degrees.
[Monday]
Snow showers or flurries early in the morning followed by partly to mostly cloudy and cool conditions with highs in the mid 30s to around 40 degrees.
