Warm temperatures were welcome over Iowa on Tuesday with record highs set at a few locations in western Iowa. Such nice temperatures will be swept out of the state during the day on Wednesday and we will be left with a cold Thanksgiving Day. The high temperature is expected to be at or just below freezing over much of the state. Having such cold on Thanksgiving isn't too out of the ordinary. The featured chart presents Thanksgiving Day high temperatures for Des Moines. Please note that such climatology can be tricky for sites that do not report values on the calendar day, but around 7 AM, so Des Moines was chosen as one of the sites that does do calendar day observations. Outside of the chilly temperatures, the weather will be excellent for travel otherwise with not much in the way of storms over the central US.
