DISCUSSION
ISSUED AT 1050 PM CDT SUN JUN 7 2026
AN UPPER LEVEL JET WILL SUPPORT CONTINUED RAIN CHANCES INTO
MONDAY. MOISTURE ADVECTION UNDER THIS JET HAS MAINTAINED
ANOMALOUSLY HIGH PWAT VALUES (2-2.5") ACROSS THE REGION. THERE IS
A LOW (10-30%) CHANCE OF SHOWERS ALONG THE COAST PRIOR TO SUNRISE,
MOVING INLAND THROUGH THE DAY. THE GREATEST CHANCE (20-40%) OF
SHOWERS AND THUNDERSTORMS IS THIS AFTERNOON/EVENING WEST OF I-69C,
WITH BRIEF, HEAVY SHOWERS POSSIBLE REGION-WIDE.
HIGH PRESSURE BUILDING OVER THE GULF WILL BRING DOMINANT RIDGING
OVER DEEP SOUTH TEXAS FOR MUCH OF THE WEEK, SUPPRESSING DEEPER
MOISTURE ADVECTION AND RAIN CHANCES. RELATIVE HUMIDITY GREATER THAN
40% AND HIGH TEMPERATURES IN THE 90S WILL LEAVE A PERSISTENT
MODERATE RISK OF HEAT RELATED ILLNESS THROUGHOUT THE WEEK.
TEMPERATURES WILL GRADUALLY INCREASE OVER THE NEXT COUPLE DAYS, WITH
HEAT INDICES IN THE TRIPLE DIGITS - UP TO 110 IN THE UPPER RGV BY
MIDWEEK. HEAT ADVISORIES ARE UNLIKELY AT THIS TIME. LOW TEMPERATURES
FLIRT NEAR RECORD MAXIMUMS, PERSISTENTLY IN THE MID 70S TO LOW
80S.
AT LOCAL BEACHES, INCREASED SWELL AND WAVE HEIGHTS MAINTAIN
HAZARDOUS SWIMMING CONDITIONS WITH A MODERATE RISK OF LIFE
THREATENING RIP CURRENTS.
