Yep, soil temps have been unusually warm lately:

However, an arctic airmass is forecast to sag all the way down to the Gulf coast early next week, bringing icy precip, perhaps some snow and, most importantly, lows in the lower teens - Good news, though, is that models are hinting for 2 subsequent rounds of precip. The more precip we get, the better; to maintain that soil moist under those leaves!
