*WINTER STORM WATCH*

The National Weather Service in Duluth, Minnesota has issued a winter storm watch for parts of Northeast Minnesota and Northwest Wisconsin.  This watch is in effect from late Saturday Night through Sunday Evening.  The following counties are included in this watch:  In Minnesota...Carlton and Southern St. Louis.  In Wisconsin...Douglas...Bayfield...Ashland...and Iron.  Some cities included in the watch:  Duluth MN...Cloquet MN...Moose Lake MN...Superior WI...Solon Springs WI...Port Wing WI...Bayfield WI...Cable WI...Ashland WI...Butternut WI...Upson WI...Gile WI...Montreal WI...and Hurley WI.

Impacts:  Light snow will move into the watch area Saturday Night and will continue through Sunday Evening.  There is uncertainty on how far north the heavier snow will get, thus this is a low confidence winter storm watch.  East-northeast wind coming off Lake Superior could also cause heavier lake effect snow showers along the South Shore of Lake Superior back through the Twin Ports Sunday and Sunday Night, this potential is low, however, due to a strong area of high pressure which will be centered to our north which may feed enough dry air south out over Lake Superior to prevent any lake effect snow from occurring.  If lake effect snow becomes more of an issue, or the heavier snow from the Plains low pushes farther north, then the combination of falling snow and increasing winds on Sunday would cause significant amounts of blowing and drifting snow with visibility as low as one quarter mile.  There is a potential for several inches of snow in the watch area by Sunday Night.
