Fall Freeze Stats & Possible Cool Plunge?

Some farmers have already mentioned to me their thoughts are trending toward the first Fall frost/freeze. Some are predicting an earlier frost or freeze than average, based on personal observations ranging from nuts to the activity of certain birds or animals. I am always fascinated by these nuggets of observational experience. Here are the climatological values for the first Fall freeze for Richmond:

Average First Fall Freeze (reaching 32 degrees F): October 29
Earliest First Fall Freeze on record: October 3, 1974
Latest First Fall Freeze on record: December 2, 1985
But maybe the farmers are onto something. As Aaron mentioned over the weekend, the long-range weather pattern is showing some indication that a strong cold front will move into Central Virginia around mid-October. Based on the latest data, it appears this strong cold front may arrive in Virginia around October 13-14th. The coldest temperatures would affect New England, but it does appear that we have a good chance of getting some of the cold plunge in the Commonwealth, too.
We'll be keeping an eye on this developing weather pattern!

Grace In The History Books

Grace has been absorbed Tuesday by a frontal boundary in the Northeast Atlantic, losing its tropical characteristics and weakening. The remnants of Grace will bring rough weather for that part of the Atlantic while continuing to be swept along with the approaching cold front.
Grace's remnants are moving north-northeast along this boundary, and it looks like the timing of the cold front and what's left of Grace will bring heavy rain to Central England later Tuesday.
