The upland location allows some of the periodic Gulf of Mexico moisture to interact with frontal systems and elevated terrain to create more clouds and precipitation than locations in the brush country to the south, or the steppes and deserts to the west and northwest. Thunderstorms with heavy rainfall are most frequent during spring and fall months, though some lighter, steady precipitation and low clouds can occur during the winter, due in large part to frontal systems originating on the plains and prairies to the north.Summers are long and hot, often with higher humidity, though a good breeze often moderates the heat. Fall through spring months are often pleasant, though winter can experience brief periods of cold or cloudy weather.
