After melting much of the snow that has fallen in the past few weeks, we are in store to receive some more. The National Weather Service has issued many advisories and warnings ahead of this next winter storm. There is a winter storm warning (counties in the pink) that goes into effect at 4pm this afternoon through 7am Monday morning. The winter storm warning extends from Des Moines to the Northeast towards Dubuque. This is the area that will receive 5”-9” with locally higher amounts, and winds sustained from 20-30mph, gusting up to 40mph at times. Western Iowa is placed under a winter weather advisory (counties in purple) which is in now in effect until 2am Monday. This area can expect snow accumulations of 3”-5” with sustained winds from 20-30mph, with winds gusting up to 40mph at times. Southeast Iowa is going to miss the brunt of this storm as they are only expected to receive 1”-2” of snow with winds from 10-20mph.
Rain will continue to fall this afternoon and will eventually start to transition over to mix precipitation before finally changing to all snow. During this transition time, it is possible that areas North of highway 30 could expect a light glazing of ice as the precipitation transitions to snow. Travel conditions are expected to rapidly deteriorate this afternoon and become very hazardous tonight. Visibilities may drop below a half mile due to the combination of the heavy snow and winds.
