DISCUSSION
(THIS EVENING THROUGH NEXT TUESDAY)
ISSUED AT 1250 PM CDT WED JUL 8 2026
SURFACE ANALYSIS DEPICTS WEAK HIGH PRESSURE OVERHEAD, PROVIDING A
LIGHT SOUTHWEST TO WEST FLOW ACROSS THE FORECAST AREA. ALOFT, A
WEAKNESS REMAINS OVER THE ARK-LA-MISS, WITH WEAK RIDGING TO THE WEST
AND EAST. AREA RADAR SHOWS A FEW ISOLATED SHOWERS AND STORMS ONGOING
ALONG AND SOUTH OF THE I-10 CORRIDOR THIS AFTERNOON, WITH COVERAGE
SLOWLY EXPANDING AS WE MOVE TOWARDS MAX HEATING HOURS. THE WEAKNESS
ALOFT WILL PROVIDE SOME ADDITIONAL SUPPORT FOR CONVECTION THIS
AFTERNOON HOWEVER, IT DOESN'T LOOK LIKE COVERAGE WILL BE QUITE THAT
OF THE LAST FEW DAYS. NEVERTHELESS, WPC HAS ONCE AGAIN OUTLINED THE
ENTIRE FORECAST AREA WITHIN THE MARGINAL RISK FOR EXCESSIVE RAINFALL
TODAY. WITH ONLY SCATTERED ACTIVITY EXPECTED THIS AFTERNOON, THE
INCLUSION OF THIS OUTLOOK IS STRICTLY TO COVER THE POSSIBILITY OF
SLOW MOVING HEAVY DOWNPOURS THAT COULD CAUSE VERY LOCALIZED FLOODING
ISSUES OVER MORE URBAN AREAS. OTHERWISE, IT LOOKS LIKE (SHOCKER)
ANOTHER HOT AND HUMID AFTERNOON WITH HIGHS REACHING INTO THE LOW TO
MID 90S.
TOMORROW AND FRIDAY, WHAT REMAINS OF THE WEAKNESS ALOFT CONTINUES TO
BREAK DOWN AS RIDGING TO THE WEST AND EAST EXPAND TOWARDS EACH OTHER
OVERHEAD. AS WEAK RIDGING BECOME SITUATED ACROSS THE SOUTHERN CONUS
THROUGH THE END OF THE WEEK, IT WILL TAMPER OUR DAILY CHANCE FOR
SHOWERS AND STORMS DOWN A BIT FOR A COUPLE OF DAYS. WHILE WE WON'T
DRY OUT COMPLETELY, WE WILL SEE MUCH MORE SUNSHINE THAN RAIN THROUGH
THE NEXT COUPLE OF DAYS. TEMPERATURE WISE, WE CONTINUE TO REACH INTO
THE LOW TO MID 90S THROUGH THE AFTERNOON, WITH HEAT INDICES PEAKING
IN THE MID 100S.
BY THE WEEKEND, POPS RAMP UP ONCE AGAIN AS UPPER RIDGING SHIFTS WEST
AND BECOMES SITUATED OVER THE ROCKIES ALLOWING A WEAKNESS TO DEVELOP
OVERHEAD ONCE AGAIN. THIS WEAKNESS ALOFT TOGETHER WITH THE
SEABREEZE/DIURNAL HEATING WILL RESULT IN MORE WIDESPREAD AFTERNOON
ACTIVITY EACH DAY FROM SATURDAY INTO EARLY NEXT WEEK. THIS WILL KEEP
AFTERNOON HIGHS IN THE UPPER 80S TO LOW 90S, WITH MAX HEAT INDICES
IN THE LOW TO MID 100S.
AVIATION
(18Z TAFS)
ISSUED AT 1212 PM CDT WED JUL 8 2026
SCATTERED SHOWERS AND THUNDERSTORMS WILL CONTINUE ALONG/SOUTH OF
THE I-10 CORRIDOR INTO THIS EVENING, POSSIBLY EXPANDING FURTHER
NORTH LATER THIS AFTERNOON AS WELL. LIKE THE LAST FEW DAYS, IF ANY
OF THESE STORMS PASS OVER THE TERMINALS THEY WILL BE CAPABLE OF
PRODUCING HEAVY DOWNPOURS THAT CAUSE REDUCTIONS IN VIS ALONG WITH
FREQUENT LIGHTNING. OUTSIDE OF THESE STORMS, VFR CONDITIONS AND
LIGHT AND VARIABLE WINDS SHOULD PREVAIL THROUGHOUT THE FORECAST
PERIOD.
MARINE
ISSUED AT 1250 PM CDT WED JUL 8 2026
SURFACE HIGH PRESSURE WILL REMAIN STRETCHED FROM THE ATLANTIC INTO
THE NORTHERN GULF THROUGH THE WEEK. THIS WILL KEEP A LIGHT SOUTH TO
SOUTHWEST FLOW AND LOW SEAS IN PLACE. ISOLATED TO WIDELY SCATTERED
SHOWER AND STORMS WILL BE POSSIBLE EACH DAY, WITH COVERAGE
INCREASING A BIT BY THE LATE WEEKEND INTO EARLY NEXT WEEK AS ANOTHER
WEAKNESS DEVELOPS ALOFT.
FIRE WEATHER
ISSUED AT 1250 PM CDT WED JUL 8 2026
NO FIRE WEATHER CONCERNS AT THIS TIME. ISOLATED TO WIDELY SCATTERED
STORMS ARE EXPECTED TODAY ALONG THE SEA BREEZE, HOWEVER COVERAGE
WILL DECREASE THURSDAY AND FRIDAY AS AN UPPER RIDGE BUILDS IN.
