ISSUED AT 1048 PM CST SUN NOV 23 2025  
 
HOT, PRIMARILY RAIN-FREE CONDITIONS ARE EXPECTED TO CONTINUE THROUGH  
TUESDAY, WITH HIGH TEMPERATURES WELL ABOVE NORMAL FOR LATE NOVEMBER.  
DAILY HIGH TEMPERATURE RECORDS WILL BE NEARED, TIED, OR BROKEN. A  
LOW-LEVEL JET WILL MAINTAIN GUSTY SOUTHEASTERLY WINDS, AROUND 30 KTS  
MONDAY AHEAD OF AN APPROACHING INITIAL FRONTAL BOUNDARY. THIS  
BOUNDARY MAY DRIFT INTO THE RIO GRANDE PLAINS AND BRUSH COUNTRY LATE  
THIS AFTERNOON, BRINGING A SHIFT OF WINDS FROM THE NORTH BEFORE  
STALLING. AT LOWER TEXAS BEACHES, THERE IS A HIGH RISK OF RIP  
CURRENTS THROUGH MONDAY EVENING.  
 
TUESDAY NIGHT, A SECOND COLD FRONT ACCELERATING ACROSS THE CWA WILL  
PROVIDE A MEDIUM CHANCE OF RAIN (40 TO 60%) OVERNIGHT INTO EARLY  
WEDNESDAY ACROSS THE CWA, WITH A LINGERING LOW TO MEDIUM CHANCE OF  
SHOWERS (20 TO 40%) THROUGH WEDNESDAY AFTERNOON ALONG THE RIO  
GRANDE. THERE IS A CHANCE FOR STRONG THUNDERSTORMS ALONG THE FRONT.  
 
COOLER AIR WILL ADVECT IN BEHIND THE FRONT, BRINGING MORE SEASONABLE  
TEMPERATURES WEDNESDAY AND THURSDAY. THESE WILL NOT LAST LONG, AS  
ABOVE-AVERAGE TEMPERATURES GRADUALLY RETURN FRIDAY ONWARD.
