Winter Storm: Dec. 23-25 Update #1

Roadways across northern Iowa and adjacent areas are slick in spots this morning as a layer of ice has fallen during the overnight hours, and may continue to lightly accumulate this morning across parts of the state.  Snow may begin to fall this afternoon across portions of northern Iowa, as well as other areas of eastern KS/NE/SD today.  This snowfall will likely continue through the day on Friday across northern Iowa and other areas of the northern plains, with snow totals reaching well above a foot over a significant part of the Dakotas, Minnesota, Iowa, Nebraska, and a few adjacent areas.  Other areas just south and east of this heaviest snow will see a mix of snow and sleet, and perhaps a few more hundredths to a tenth of ice accumulation as well.  Even further south and east with this system will see several inches of rain on top of the frozen ground, creating flooding hazards in some areas.

Luckily, I find myself in the best probabilities for over a foot of snow as rated by the HPC for both today and tomorrow.  I'll continue to post updates as I can as the snow begins to accumulate over the area.  The next update I'll give later this morning will have the latest model runs and their forecast snow accumulations.  Below is the latest Des Moines weather story, which gives a pretty good summary for the state of Iowa:
