Labor Day weekend weather turned out to be gorgeous across the Mid-South, particularly Saturday and Sunday, as cool and dry high pressure dominated the region. Dewpoints (a measure of humidity) dropped to their lowest levels since spring, making temperatures in the 80s feel even better. The low dewpoints also contributed to morning lows in the 50s, the coolest since mid-May. As high pressure moves east and wind takes on a more southerly component, temperatures today (Labor Day Monday) will warm into the lower 90s, though humidity will remain low.
As we move into Tuesday, a warm front will pass through from south to north. The front will not necessarily cause warmer temps, but will markedly increase the humidity factor by drawing considerably more moisture into the region from the Gulf of Mexico. The origin of some of this moisture will be Tropical Storm Hermine, which is currently approaching the south Texas coast and will move north through Texas on Tuesday. With increasing moisture and humidity, look for scattered showers and a few thunderstorms on Tuesday and Wednesday with a slight chance Thursday as well. Highs will still push to near 90 or better, but the increased humidity levels mean lows remain in the 70s, rather than 50s and 60s. It appears another cold front could move into the region this weekend, so rain chances will likely increase again, especially Sunday.
