Weekend System (Forecast Update)

Models are still in good agreement and the consensus is starting to be made on what will happen over the weekend with this storm system. Some areas of Iowa have woke up to be under a Winter Storm Watch, this runs north of a line from Clinton, IA to Waterloo then to Fort Dodge, IA. The Sioux Falls NWS has yet to issue any watches, as the risk is a little less over there area. The Winter Storm Watch has been issued as these areas are under the best risk for a potential ice event Friday night into Saturday. Des Moines has stated that there is the possibility for over .25 inch of ice before the event turns completely over to snow Saturday night.

The rest of the state should see mainly rain over Friday into Saturday, with some fairly high amounts possible. Thus, flooding is also a concern for most of the state; already a major concern in Nebraska where flood statements are already being issued. The rain should come to an end by Saturday night, where the entire state should see the changeover to snow. Most of the state is in a good chance of seeing anywhere from 5-8 inches of snow with this system as it finally dissipates later Sunday. Some areas will have the possibility of even higher amounts dependent on the track of the low as well as speed. If the low slows down even slightly the total precip amounts could be significantly higher. Most of the state should keep a close eye on this system as it has some significant winter potential...
