Tonight (February 8)

Low pressure will continue to sit and spin over the Eastern Great Lakes tonight.  Scattered snow showers and flurries will linger in parts of the Northland tonight with heavier lake effect snow showers persisting along the South Shore of Lake Superior affecting Douglas, Bayfield, Ashland and Iron Counties.  Low temperatures will range from the single digits below to around 10 above zero with north or northwest winds at 10 to 20 mph with locally higher gusts.  Areas of blowing and drifting snow will continue tonight especially in open areas.

Note:  There is also a chance for another gravity wave to develop this evening along the North Shore of Lake Superior, if this does develop then there could be locally moderate to heavy snow showers at times tonight that would affect locations close to Lake Superior including Southeast St. Louis, Southern Lake and Southern Cook Counties, extending down into Eastern Carlton and Northeast Pine County.  A few inches of snow could accumulate along the North Shore of Lake Superior tonight but confidence of this actually occurring is on the low side late this afternoon.

Tuesday and Tuesday night (February 9)
