Iowa: Predicting 1st Fall Frost, Freeze Dates?

When will the first hard freeze or killing frost (equal to or less than 28°F) date be this fall? This is a question a lot of folks are wondering about right now. Over the last few decades the trend for the first frost and freeze dates in the fall has been that they are occurring later in the season when compared to the long-term behavior.

The figures below illustrate the average first freeze (32°F) and frost (28°F) dates across the Midwest from 1980 to 2010. While these figures show us what the average freeze and frost dates have been, it is too early to make any predictions about frost and freeze dates for this year yet.
