DISCUSSION
(THIS AFTERNOON THROUGH NEXT TUESDAY)
ISSUED AT 1122 AM CDT WED AUG 5 2026
TYPICAL SUMMER PATTERN LOOKS TO CONTINUE THROUGH OUR DAY-TO-DAY
FORECAST WITH LITTLE CHANGE EXPECTED. UPPER LEVEL RIDGING IS
CURRENTLY CENTERED OVER NEW MEXICO AND A WEAK UPPER LEVEL TROUGH
SITUATED IN THE EASTERN GULF IS LEADING TO VERY WEAK UPPER LEVEL
FLOW OVER OUR AREA. DIURNALLY DRIVEN SHOWERS WILL PERSIST DAILY
OVER SECTIONS OF OUR AREA. WEAK UPPER LEVEL FLOW WILL LEAD TO SLOW
MOVING STORMS, BUT THE AVERAGE PWAT VALUES DAMPEN THE CHANCES FOR
FLOODING RAINFALL.
A SURFACE HIGH PRESSURE IS SITUATED OVER THE EASTERN GULF IS
BRINGING LIGHT SOUTHERLY WINDS OVER OUR AREA. CURRENTLY SPORADIC
STORMS HAVE BEGAN TO INITIATE OVER MUCH OF THE REGION. OUTFLOW
BOUNDARIES AND CLOUD SHADING WILL LIKELY KEEP HEAT INDICES FROM
REACHING THE VALUES REQUIRED FOR A HEAT ADVISORY. MODEST DCAPE
VALUES SUGGEST A SMALL CHANCE FOR LOCALIZED STRONG DOWNDRAFTS IN
CONVECTION THROUGH THIS AFTERNOON.
