Winter weather hazards map.

Purple=Winter Weather Advisory
Red=Blizzard Warning
Green=Blizzard Watch

*Snowfall map* (Updated at 1:29 PM CST)  Total snowfall accumulations from late Tonight through Tuesday.  I'm still a little concerned on how quick this system will be moving, so it may be difficult to get more than 3-4", but we shall see.  The past couple of SREF model runs have been showing favorable snow growth -- dendritic growth zone...So this could lead to larger snowflakes and a more rapid accumulation of snow.

...Update on the approaching snow system...

Almost all of Northeast Minnesota and all of Northwest Wisconsin is under a *Winter Weather Advisory* More information can be found at this link:
