Blue on the two maps below=Snow

Here's my snowfall accumulation map for Friday PM-early Saturday AM.  Note:  I may have to adjust the 3-5" and 1-2" zones a little bit more to the south by later this evening or tomorrow morning as the computer models have trended slightly more to the south with the track of Friday's clipper.

Weather Synopsis:

Low pressure moved into eastern Canada today but a cyclonic flow on the backside of this low combined with some upper level disturbances rotating south/east across the upper Midwest kept snow showers and flurries going over the Northland today along with mostly cloudy skies although there have been a few peeks for sun every now and then.  Highs were in the 20s so not very cold as we get toward the end of the month.  West or northwest winds at 10 to 20 mph with higher gusts did put a little chill in the air though despite the relatively 'mild' late December temperatures.

*Snow showers and flurries continue in parts of northeast Minnesota and northwest Wisconsin this evening with accumulations less than 1".  Mostly cloudy skies with some clearing expected to develop as the night wears on as high pressure exerts its muscle into the Northland.  Lows tonight will be in the single digits below zero to around 10 above.

*Some sunshine is possible Friday morning but clouds will be on the increase as low pressure approaches from the northwest -- Snow will spread into western portions of the Northland Friday afternoon, the snow will then push farther south/east and should cover most of northeast Minnesota and northwest Wisconsin by early Friday evening.  Snow ratios are forecast to be in the 10:1 to around 20:1 range with this event so generally a fluffy snowfall is expected.  Highs on Friday will be in the teens and 20s.
