Winter Storm: Dec. 27-28

Yet another low pressure system is going to make its' way across the plains states, leading to another shot at heavy snowfall over portions of the state of Iowa. Snow should begin to enter the state late this afternoon and throughout the night, lasting into the daytime hours tomorrow for much of eastern Iowa along with some flurries left over for southern Iowa. Areas of the state have been put under a Winter Storm Watch that will likely be upgraded to at least a Snow Advisory later this afternoon. Areas currently not under the watch may still be upgraded to some sort of advisory as the path of this system may go slightly north than the Des Moines forecast office has indicated with their watch area. Models are in line fairly well with the track and amounts from this system, the area of more than 1 inch of snow should be east of a line from Nebraska City, NE through to Rochester, MN. Areas west of that line are likely to only see snow flurries with accumulations less than an inch.

Amounts east of that line area likely to range from 1" to upwards of 5" with some half-foot amounts possible in some of the heavier bands of snow. The Davenport NWS has put wording in their forecast that isolated 5-8" amounts are not out of the question. Models currently paint the heaviest snowfall amounts between 5" and 7", this mainly in areas of southeastern and eastern Iowa.
