Episode Narrative The seasons first major winter storm moved into Iowa on the 1st. The system developed in the east Pacific off the California and Mexico coasts and lifted northeast into the central U.S. A very strong push of warm air moved into the central U.S. ahead of the storm. Prior to the storms arrival, polar air was in place with temperatures in the teens and 20s and dew points in the single digits above and below zero. Precipitation moved into the area during the predawn hours on the 1st. Initially the precipitation fell as snow, but with the intense warm air advection it turned to freezing rain and sleet very quickly over southern Iowa, and within a few hours after inception over the north. Surface temperatures were slow to warm due to evaporative cooling. In spite of winds in the low levels between 900 and 800 mb being in the 70 plus knot range, surface temperatures warmed very slowly. Eventually, the surface low pressure system lifted northeast through west central into northeast Iowa resulting in temperatures rising above freezing in most areas. Freezing rain was widespread over much of the south two thirds of iowa. Widespread ice accretions of at least one quarter of an inch of ice were reported. Heavier icing occurred southwest of Des Moines in Adair and Madison Counties with widespread ice accumulations of up to three quarters of an inch. One half to three quarter inch ice accumulations were common across the south tier of counties from Interstate 35, east. The ice resulted in some tree and power line damage with scattered power outages reported. Southeast winds of 20 to 35 MPH caused branches to break, knocking out power for thousands of customers by the afternoon of the 1st. Ice and ice pellets produced very slippery runway conditions at the Des Moines International airport. One plane slid off the tarmac, resulting in a 7 hour closure of the airport. The secondary problem that took place over nearly all of Iowa was heavy ice pellet accumulations. Many areas reported one half to 1 inch of sleet accumulation, resulting in considerable travel difficulties. Over the northern part of the state, roughly from U.S. Highway 20 north, one to three inches of snow fell, with spotty amounts of up to 4 inches. In addition to the snow, sleet was reported for several hours during the afternoon with accumulations of up to one half inch. Freezing rain did occur as well, but the freezing rain was not all that extensive or heavy.
