A widespread ice storm affected eastern Nebraska and western Iowa Saturday December 1st, 2007. Warm and moist air spread rapidly north across the region on a strong low level jet that was in excess of 50 mph. The moisture fed north over a retreating Arctic air mass, with temperatures in the 20s and dew point temperatures in the single digits and teens just after midnight. The freezing precipitation began over much of the area between 3 and 4 am, and was preceded or initially mixed with a little sleet. Surface temperatures and dew points climbed to freezing or a bit above about 5 to 7 hours after the precipitation began.  Ice accumulations of around 1/4 inch fell over most of the area. Although there were reports of tree limbs down, traffic accidents and power outages, the rise in temperatures to freezing and above helped mitigate a lot of the damage.
