DISCUSSION
(THIS AFTERNOON THROUGH NEXT WEDNESDAY)
ISSUED AT 1141 AM CDT THU AUG 6 2026
WEATHER PATTERNS IN THE FORECAST AREA WILL LARGELY REMAIN TYPICAL
FOR THE SEASON, WITH HIGHS IN THE LOW 90S AND LOWS IN THE UPPER
70S. A SURFACE RIDGE ALONG THE SOUTHEAST AND GULF COASTS WILL
RESULT IN SOUTHERLY SURFACE WINDS THAT WILL TRANSPORT WARM, MOIST
AIR FROM THE GULF INTO THE FORECAST AREA. CONSEQUENTLY, DEW POINT
TEMPERATURES WILL BE IN THE MID TO UPPER 70S, CREATING A MUGGY
DAYTIME ENVIRONMENT WITH AFTERNOON HEAT INDEX READINGS RISING
ABOVE 100 DEGREES. AT NIGHT, THIS HIGH RELATIVE HUMIDITY, COUPLED
WITH CALM WINDS OF 3-7 MPH WILL ALLOW FOR AREAS OF PATCHY FOG TO
DEVELOP IN THE EARLY MORNING HOURS OF FRIDAY AND SATURDAY.
AN UPPER LEVEL RIDGE CENTERED OVER THE SOUTHWEST US WILL BRING
NORTHEASTERLY FLOW IN THE MID AND UPPER LEVELS OF THE FORECAST
AREA. HOWEVER, THE RIDGE IS NOT EXPECTED TO HAVE ANY SUPPRESSIVE
INFLUENCE ON AFTERNOON CONVECTION.
AFTERNOON SHOWERS AND THUNDERSTORMS INITIATED BY DAYTIME HEATING
AND SEA BREEZE ARE POSSIBLE EACH DAY HEADING INTO THE WEEKEND, BUT
SIGNIFICANT RAINFALL IS NOT EXPECTED. HOWEVER, ISOLATED AND SLOW
MOVING STORMS MAY PRODUCE LOCALLY HEAVY RAINFALL AMOUNTS THAT
COULD CAUSE MINOR FLOODING IN LOW-LYING AREAS WITH POOR DRAINAGE.
