Summer weather may come from [[Texas]] (very hot and humid) or the Gulf (hot and very humid). July has a daily average temperature of {{convert|82.8|°F|1}}, with high levels of humidity due to moisture encroaching from the Gulf of Mexico. Afternoon and evening thunderstorms are frequent during summer, but usually brief, lasting no longer than an hour. Early autumn is pleasantly drier and mild, but can be hot until late October. Late autumn is rainy and cooler; precipitation peaks again in November and December. Winters are mild to chilly, with a January daily average temperature of {{convert|42.1|°F|1}}. Snow occurs sporadically in winter, with an average seasonal snowfall of {{convert|2.7|in|cm|1}}. Ice storms and freezing rain pose a greater danger, as they can often pull tree limbs down on power lines and make driving hazardous. Severe thunderstorms can occur at any time of the year though mainly during the spring months. Large hail, strong winds, flooding, and frequent lightning can accompany these storms. Some storms spawn tornadoes.
