Despite an approaching cold front, Thursday afternoon is expected to be another HOT one for much of west Texas. An Extreme Heat Warning and another Heat Advisory are in effect during the afternoon and evening hours.
Hot conditions continue Thursday ahead of an approaching cold front. Highs beyond the century mark are forecast for much of the Permian Basin, southeast New Mexico, and both the Upper and Lower Trans Pecos. Stay cool and drink plenty of fluids if you must be outdoors!
Hazardous heat is forecast Thursday. Be sure to take precautions if exposed to prolonged periods of heat!
A couple of showers and thunderstorms may develop over the higher terrain this afternoon before additional development occurs along a cold front this evening.
