Monday morning update on midweek storm

With the latest forecast model runs, we are starting to see more agreement for the projected track of the storm system that is expected to arrive late Tuesday into the first half of the day Wednesday.

Both the GFS and European models put the snow line starting roughly at Red Wing, Minnesota.  Rochester could see a couple inches of snow, while places such as Winona and La Crosse, Wisconsin could pick up close to five inches of snow.  Enough to shovel.  The Twin Cities could see some flurries mixed with rain showers, but nothing significant.

Across southeast Minnesota, the available moisture that the storm will have to work with will be good for producing snow.  No dry layers of air are shown towards the surface.
