WINTER ALERT: Watch Posted for Parts of State

imageThe National Weather Service has begun posting its advisories and watches for this weekend winter storm system.  As you can see in the graphic to the left, a good portion of western Iowa is currently under a Winter Storm Watch.  This watch will be clarified into either a Winter Weather Advisory or a Winter Storm Warning one the final outcome becomes more clear.

At this time, anywhere from 2”-7” of snow is possible in this area.  I would anticipate that depending on how the final track of this storm plays out, we could see additional counties placed in a Winter Weather Advisory further to the east.

As you can see in the graphic, to the west of what watch (in green), you see the advisory area (in blue).  This is where accumulations of 1” to 5” are possible.  The rain-snow line during this storm is expected to take shape over Des Moines and Waterloo.  These are some pretty populated areas that, with one minor shift, could see a light snow turn into a heavy one.  At any rate, the area west of these locations at this time appears to be at most risk of significant snowfall, or 6+” when all is said and done.

By the end of the weekend, everyone should see snow, but eastern Iowa may only see light accumulations.  Before that happens a lot of rain will fall on Saturday so travel will still not be ideal.  We will continue to monitor any changes in this forecast and bring you the very latest.
