Key Messages...
1) Lake effect snow affecting northern Iron County early this morning to come to an end within the next few hours. We have a a Winter Weather Advisory in effect until 6 AM.
2) A wave of snow will move across the area this afternoon and tonight bringing light snowfall amounts to mainly the Arrowhead and Borderlands, with amounts of less than 2 inches.
3) Much below normal temperatures this morning to moderate through the middle part of the week, with near to above normal temperatures for the latter half of the week and next weekend.
Our weather radar is currently mostly overshooting the lake effect snow showers that are streaming over northern Iron county, but satellite shows streamers of clouds that are bringing light snow to Ironwood and also periodically to La Pointe. These clouds have been weakening over the Bayfield Peninsula so far this morning as generally drier air moves into the area from the west.
The wind direction has been slowly shifting from northwest to the west, which should help push the lake effect streamers east of the area, and reducing the snowfall rates over northern Iron county.
For now, these trends support the expiration time of 6 am of the Winter Weather Advisory, but it may need a short term extension depending on these trends. Temperatures early this morning have gotten well below normal, with a large portion of the area in the single digits, with parts of northeast MN even below zero. The coldest temperatures are under a ridge axis where skies have also cleared over the western portions of the forecast area.
A new clipper will move across the forecast area this afternoon and evening, which should produce an area of light snow that will affect mainly the Arrowhead of MN, bringing light snowfall amounts of an inch or less to much of the Arrowhead. One exception is the very tip of the Arrowhead, where around 2 inches are possible today and tonight. The strong warm air advection aloft that is part of this shortwave will also allow temperatures to warm significantly today, with high temperatures rising into the 20s for most of the area. Even as this shortwave moves back out of the area tonight snow showers will linger overnight tonight and even into Wednesday morning. Temperatures warm to above normal on Wednesday, then cool back off again for the latter half of the work week as more cold air moves back into the area again for Thursday and Friday. Thursday and Friday currently appear to have a dry forecast, but I would not rule out some flurries/light snow showers as we remain in a cyclonic flow pattern that together with a weak ripple could produce them.
Late this weekend and early next week a fairly strong upper level trough axis will move across the region. For now the best chances appear to be on Sunday, with some chance pops on Saturday night and Sunday before it moves off to the east on Monday. There is rather poor agreement in the operational models starting Sunday night, but the ensembles show that an upper level low moves across the central CONUS Sunday through Tuesday, supporting the precipitation chances. Temperatures remain near to above normal through this time range.

Largely VFR conditions are expected for the rest of today. Some sites expecting light snowfall from a passing clipper this afternoon and evening could see brief reductions in visibility and/or ceiling to MVFR. Low level wind shear is expected this afternoon and into the evening for most sites due to winds aloft reaching as high as 40 kts. Ceilings will lower briefly overnight as cold air behind today's clipper is advected over northeastern Minnesota and portions of northwest Wisconsin.

A ridge of high pressure settling over western Lake Superior has allowed winds to diminish this morning, and have expired or cancelled the Small Craft Advisories that were in effect overnight. There may be some locally stronger wind gusts for a few more hours early this morning, but these too should diminish. Once the ridge axis slides east of the area by mid morning, allowing winds to turn to the west and then southwest by mid morning with speeds rapidly increasing again. Have issued an suite of Small Craft Advisories for all of the zones starting at 10 AM, then upgrading the Outer Apostle Islands zones to a Gale Warning at 6 PM until midnight tonight. A few other locations may also experience a few Gale force gusts, but should be limited in area or time and have refrained from upgrading any other zones. Winds gradually turn to the west tonight, and waves remain built up through Wednesday before diminishing again Wednesday night.
