Thunderstorms begin to occur more often throughout April and May and can include destructive winds and large hail. May is historically the wettest month of the year, but periods of rainy weather usually only last for a day or two. Although the area is in tornado alley, hail damage is usually the bigger concern.
Summers are usually sunny, hot and dry with little variation from day to day. The hottest months are July and August with an average high around 96 degrees, but it is not uncommon for the temperature to exceed 100 degrees.
Fall is usually very delightful. And although the weather does begin to change more frequently, there are usually long periods of mild, sunny weather to enjoy. Rainfall tends to increase in September, but it gradually gets drier throughout October and November.
