First Freeze of Fall 2006
The low temperature this morning (Thursday, October 12) reached 31 degrees at Indianapolis International Airport. This marks the first freeze of the fall season, and the first time since April 9 of this year that the low temperature has fallen to freezing or below.
In terms of the normal first freeze, this was slightly earlier than normal. October 16 is considered the normal date of a first freeze for the Indianapolis area, but this can be highly variable from year to year.
The earliest date of the first freeze on record was September 30, 1993. The latest on record was November 27, 1902. It is important to note that in 1902 the official temperature observation for Indianapolis was taken downtown in a heavily urbanized location. The latest date for a freeze since the observation was moved to the more rural airport location in 1943 was on November 8, 1956.
Temperatures will be well below normal today, with a high of 48 degrees forecasted. This is well below the normal high of 67 degrees. In fact, 48 degrees would be a normal high temperature in late November.
A slow warming trend will begin over the next several days, but it is expected that low temperatures in Central Indiana will dip below freezing each of the next two nights before normal temperatures return to close out the weekend.
