Days till killing frost

Posted: 13 Oct 2014 05:47 AM

The coldest air of the season visited Iowa this past weekend with many locations reaching their first sub freezing temperature on Saturday morning. For Ames, the temperature bottomed out at 31 degrees. The featured chart presents the number of days from the first sub freezing temperature until the first sub 29 degree temperature which is considered a killing frost. The slanted grid lines simply allow you to see the date that the dots fall on. So for having the first freeze on 11 October, we've previously waited up to 20 some days for the killing frost.

Good = 12
Bad = 11
Abstain = 6
