The autumn season in Eastern Oklahoma and Northwest Arkansas is a pleasantly long transition period between the summer heat and the winter chill. Although extremes of occasional 100 degree days are possible in early September and nights in the teens are possible in late November, most of the time the weather is accommodating with a large number of mild, sunny days and cool, fair nights. Thunderstorms do occur from time-to-time, but are not as frequent as during the spring and summer months. Arctic fronts begin to return to the region by mid-autumn and can bring large contrasts in temperature over a short time. The occurrence of snow is rare, although light amounts have been recorded over the years in October and November.
