Here is a chart of the weather for cities in which there are direct flights to and from any of the airports in the state of Iowa for Wednesday, Thanksgiving Day and Black Friday and where there could be delays. Note, where some airports might have volume delays due to the holiday even if the weather is not bad, these will tend to not last very long. Other locations that have “None” on the delays may also have volume delays as well. PC stands for Partly Cloudy, MC for Mostly Cloudy, R/S for Rain/Snow. Not all of the cities shown on the chart have direct flights every day (St. Petersburg FL, Los Angeles and Las Vegas) If travelling by car, the weather across the state on Wednesday will see some rain and snow gradually ending across the state, with only a few scattered flurries likely on Thanksgiving day.
