3/21/11: UPDATE

Issued at 1:45 PM CDT, Monday, March 21st, 2011

*BLIZZARD WATCH* FOR DULUTH/SUPERIOR FROM TUESDAY MORNING THROUGH WEDNESDAY EVENING.

Blizzard watch includes Southern Lake, Southern St. Louis, and Carlton counties in Minnesota and Douglas county Wisconsin.  Some other cities in the watch are:  Two Harbors MN...Cloquet MN...Moose Lake MN...South Range WI...Poplar WI...and Solon Springs WI...

Some snow, sleet, or freezing rain could occur at times on Tuesday with the heaviest snow expected to fall from late Tuesday Afternoon through Wednesday Morning.  Total snowfall accumulations of 6-12" with locally higher amounts are possible in the watch area by late Wednesday Afternoon.  East to northeast winds will increase to 25 mph Tonight, and to 25-35 mph with gusts over 40 mph Tuesday into Wednesday.  Winds could gust as high as 50 mph in the Duluth Waterfront Tuesday Afternoon into Wednesday Morning.

The combination of falling and blowing snow will produce near zero mile visibility at times especially Tuesday Evening through Wednesday Morning.  Travel will become extremely difficult or impossible during that time.

This snow will be wet and will stick to trees and power lines, this combined with the high winds could result in power outages.

Note:  An upgrade to a BLIZZARD WARNING seems imminent based on the latest model data.

The remainder of Northern Minnesota and Northwest Wisconsin is under a *WINTER STORM WATCH* for Tuesday Morning through Wednesday Evening.  Locations along and north of a line from Northome to Cook to Lutsen may see lighter amounts of snow compared to areas farther south, thus the winter storm watch that is currently in effect for Koochiching, Northern St. Louis, Northern Lake, and Cook counties Minnesota may be dropped to an advisory.

Stay tuned for further updates...
