DETROIT - A Lake Effect Snow Warning is in effect for Sanilac and St. Clair Counties until 12 noon ET, Thursday.  Snow accumulations of 6 inches or more are possible in these counties.

A shift in the wind over Lake Huron will likely bring a constant stream of snow to communities (like Port Huron) next to and just south of the big lake resulting in several inches of snow.  Northern Macomb County will have snow, also.  The City of Detroit and the rest of Southeast Michigan will see partly to mostly sunny skies with morning lows in the single numbers and afternoon highs near 20 and wind chills below zero.

Thursday night will be very cold and mostly cloudy with temps near 10 degrees.

A storm system from the northern Plains will bring a good chance of accumulating snow for Detroit and all of Southeast Michigan Friday.  Initial estimates of 1 to 3 inches of snow are expected by the end of Friday afternoon with temps in the low 20s. 

Expected snow totals may change as the storm gets closer.  Stay tuned to Local 4 News and the Weather Page of for your latest forecast.

Saturday and Sunday will be sunnier and drier but remain very cold.  Temperatures will not even get close to the freezing mark.  Daytime temps will be in the mid 20s at best, and nighttime lows will be in the low and mid teens.

Relief from the Arctic air will arrive Monday and Tuesday as the jet stream moves north allowing milder (not as cold) air to move over southern Michigan.  Monday's highs will be in the middle and upper 30s with the chance of snow ahead of warm front.  Tuesday's highs will be near 40 with a rain-snow mix ahead of a related cold front.
