An upper level low pressure system will continue to shift east of the region tonight. This system will continue to bring light snow to area into the evening. 2 to 4 inch total accumulations are expected across inland locations.
Low level northeast winds near Lake Michigan, in combination with the relatively warm waters of the lake, and the cold air over it, will result in unstable conditions into early this evening. This will continue to bring a favorable period for lake enhanced snowfall through early this evening.
This lake enhancement will result in slightly heavier snowfall totals near the lake, with 3 to 5 inches expected. Some 6 inch amounts are possible in spots. The low level winds will shift north during the evening, which should gradually shift most of the lake enhanced snow shower activity out over the lake. It should also keep the any single lake effect snow band development offshore.
A Winter Weather Advisory remains in effect for the lakeshore counties of southeast Wisconsin, from Sheboygan south to Kenosha, until 8 pm CST this evening. Click the above link for the latest information on the advisory. The snow should diminish from west to east later tonight.
