DISCUSSION
ISSUED AT 1204 PM CDT MON JUL 6 2026
HOT AND MOSTLY RAIN-FREE CONDITIONS WILL CONTINUE INTO MIDWEEK
WITH UPPER LEVEL HIGH PRESSURE OVER THE FOUR CORNERS INTO WEST
TEXAS IN CONTROL. TEMPERATURES WILL REMAIN HOT WITH HIGHS IN THE
MID TO UPPER 90S, AND SOME TRIPLE DIGITS IN THE MID TO UPPER
VALLEY/RIO GRANDE PLAINS. HEAT INDICES WILL GENERALLY REMAIN
BETWEEN 100 AND 110 DEGREES WITH A MODERATE HEAT RISK FOR MOST
LOCATIONS, ESPECIALLY AS WE GET LATER INTO THE WEEK. RAIN CHANCES
REMAIN GENERALLY UNDER 10% THROUGH MIDWEEK.
THE HIGH PRESSURE WILL RETREAT SLIGHTLY WESTWARD MID TO LATE WEEK
WITH AN AREA OF WEAK LOW PRESSURE/TROUGHING IN THE BAY OF CAMPECHE
INTO MEXICO. THIS WILL ALLOW FOR AN INFLUX OF TROPICAL MOISTURE AND
INCREASE CHANCES OF SHOWERS/THUNDERSTORMS MID TO LATE WEEK INTO
THE WEEKEND. WITH HIGH PWAT VALUES (OVER 2 INCHES) SOME OF THIS
ACTIVITY COULD PRODUCE HEAVY RAINFALL.
THERE IS A LOW RISK OF RIP CURRENTS AT AREA BEACHES THOUGH WILL
LIKELY INCREASE TO MODERATE BY THIS WEEKEND.
