DISCUSSION
ISSUED AT 1018 PM CDT MON JUN 8 2026
MID-LEVEL RIDGING AND HIGH PRESSURE OVER THE GULF WILL DOMINATE THE
WEATHER PATTERN THROUGH MUCH OF THE WEEK, LEADING TO WARMER AND
GENERALLY DRIER CONDITIONS ACROSS DEEP SOUTH TEXAS. WHILE SUFFICIENT
LOW-LEVEL MOISTURE WILL REMAIN IN PLACE (PWATS AROUND 2"), RAIN
CHANCES WILL STAY LOW (10% OR LESS) THROUGH THURSDAY, WITH ISOLATED
COASTAL AND SEA BREEZE SHOWERS DURING THE DAY POSSIBLE. AN INVERTED
TROUGH MOVING WESTWARD LATE IN THE WEEK MAY ADVECT DEEP TROPICAL
MOISTURE INTO DEEP S TX AND SUPPORT AN INCREASE IN ISOLATED SHOWER
AND THUNDERSTORM ACTIVITY FRIDAY THROUGH THE WEEKEND. RAIN CHANCES
INCREASE TO LOW (10-20%) FRIDAY, AND LOW TO MODERATE (20-50%) FOR
MUCH OF THE WEEKEND. THERE IS UNCERTAINTY AROUND HOW FAR NORTH THIS
ATMOSPHERIC MOISTURE WILL REACH, SO CONTINUE TO MONITOR THE FORECAST
FOR UPDATES.
THE MAIN CONCERN THIS WORKWEEK WILL BE HEAT. HIGH TEMPERATURES
IN THE MID TO UPPER 90S, WITH HEAT INDICES RANGING FROM 100 TO
110 DEGREES WILL MAINTAIN A MODERATE RISK OF HEAT RELATED ILLNESS
THROUGH THE WEEK.
AT LOCAL BEACHES, A MODERATE RIP CURRENT RISK CONTINUES TUESDAY.
IN THE LATTER HALF OF THE WEEK, HAZARDOUS BEACH CONDITIONS
INCLUDING INCREASED RIP CURRENT RISK AND MINOR COASTAL FLOODING
ARE POSSIBLE AS SWELL PERIODS INCREASE AND THE APPROACH OF A NEW
MOON RAISES TIDES.
