DISCUSSION
ISSUED AT 1253 AM CDT FRI SEP 4 2026
A TROPICAL EASTERLY WAVE MOVING WESTWARD ACROSS THE NORTHERN GULF
WILL BE THE PRIMARY FEATURE INFLUENCING OUR WEATHER TODAY INTO
SATURDAY. A BROAD CIRCULATION IS EVIDENT OVER THE FAR NORTHEASTERN
GULF EARLY THIS MORNING FROM PWAT IMAGERY, WITH THE WAVE PROJECTED
TO DRIFT WESTWARD INTO SOUTHEAST LOUISIANA BY LATE THIS AFTERNOON.
INCREASING SOUTHEAST FLOW WILL BRING A VERY MOIST TROPICAL AIR MASS
INTO THE AREA, WITH PWATS RISING TO AROUND 2.4 INCHES SOUTH OF
HIGHWAY 84 TODAY, WHICH IS NEAR THE 99TH PERCENTILE OF CLIMATOLOGY.
RAIN CHANCES WILL INCREASE SUBSTANTIALLY TODAY AS A RESULT, WITH
POPS AROUND 60-80% FOR MOST AREAS SOUTH OF HIGHWAY 84. COVERAGE WILL
BE GREATEST OVER THE MARINE AREAS DURING THE MORNING HOURS BEFORE
SHIFTING INLAND DURING THE AFTERNOON. A FEW WATERSPOUTS WILL BE
POSSIBLE OVER THE GULF DURING THE MORNING HOURS. CAM GUIDANCE
SUGGESTS SOMEWHAT LIMITED COVERAGE OVER LAND THIS AFTERNOON, BUT THE
COMBINATION OF ABUNDANT MOISTURE AND FORCING FROM THE TROPICAL WAVE
SHOULD SUPPORT A FEW PROMINENT BANDS OF SHOWERS AND STORMS. ANY
STRONGER STORMS COULD PRODUCE BRIEF GUSTY WINDS AND TORRENTIAL
RAINFALL, WITH ISOLATED FLOODING POSSIBLE WHERE STORMS REPEATEDLY
MOVE OVER THE SAME AREAS. LINGERING TROPICAL MOISTURE SHOULD SUPPORT
ANOTHER DAY OF SCATTERED TO NUMEROUS SHOWERS AND STORMS (50-70%
POPS) ON SATURDAY, BUT A BIT LESS COVERAGE COMPARED TO TODAY.
RAIN CHANCES REMAIN ELEVATED (40-70% POPS) INTO EARLY NEXT WEEK AS
THE RIDGE OVER THE TENNESSEE VALLEY SHIFTS WEST AND TROUGHING OVER
THE NORTHEAST SENDS A WEAK BACKDOOR FRONT INTO THE SOUTHEAST STATES.
AS OUR FLOW SHIFTS TO NORTHERLY BY SUNDAY, THIS BOUNDARY COULD REACH
NORTHEAST PORTIONS OF OUR AREA, PROVIDING ADDITIONAL FORCING FOR
AFTERNOON STORMS AS CONDITIONS REMAIN MOIST AND UNSTABLE SOUTH OF
THE BOUNDARY. TRENDS WILL BE MONITORED FOR POTENTIAL STRONG TO
SEVERE STORMS SUNDAY AFTERNOON, AND PERHAPS MONDAY AFTERNOON AS
WELL. THE FRONT SHOULD WASH OUT BY TUESDAY AS THE RIDGE BUILDS BACK
EAST AND FLOW BECOMES MORE EASTERLY TO SOUTHEASTERLY, THOUGH RAIN
CHANCES WILL LIKELY NOT COME BACK DOWN TO MORE TYPICAL LEVELS UNTIL
AT LEAST WEDNESDAY.
HIGHS WILL RANGE FROM MID 80S TO LOW 90S TODAY AND SATURDAY,
INCREASING TO LOW TO MID 90S FOR SUNDAY AND MONDAY ALONG WITH PEAK
HEAT INDICES IN THE 103-107 RANGE. AT THE BEACHES, A LOW RISK OF RIP
CURRENTS CONTINUES THROUGH MONDAY. JGC/98
AVIATION
(06Z TAFS)
ISSUED AT 1253 AM CDT FRI SEP 4 2026
MAIN FOCUS OVERNIGHT WILL BE MONITORING A SMALL AREA OF -SHRA
DRIFTING WEST ACROSS COASTAL AL, PRODUCING A BRIEF PERIOD OF LIGHT
RAIN BUT WILL BE QUICK TO DEPART/DISSIPATE. BEYOND THAT, WILL
MONITOR ADDITIONAL SCT TSRA ACROSS COASTAL AREAS EARLY THIS MORNING
AROUND DAYBREAK THROUGH MID/LATE MORNING. INTRODUCED PROB30'S FOR
COASTAL TAF SITES DUE TO CLOSE PROXIMITY TO THIS ACTIVITY, WHICH
COULD BRIEFLY IMPACT KJKA OR KPNS WITH BRIEF REDUCTIONS IN VIS/CIGS
LEADING TO PERIODIC LOWER FLIGHT CATEGORIES IN THIS TIME FRAME.
BEYOND THAT TIME FRAME INTO THE AFTERNOON, TIMED PROB30'S FOR
FURTHER INLAND TAF SITES INCLUDING KMOB AND KBFM GENERALLY 18-23Z
FOR ADDITIONAL SCT TSRA ACTIVITY LATER TODAY, WITH THE SAME BRIEF
THREATS. OTHERWISE, EXPECT VFR PREVAILING OUTSIDE OF ANY SHRA/TSRA
ACTIVITY. KLG
MARINE
ISSUED AT 128 PM CDT THU SEP 3 2026
A GENERALLY LIGHT EAST TO SOUTHEAST FLOW PATTERN WILL BECOME WESTERLY
THIS WEEKEND. A LIGHT SOUTHERLY FLOW RETURNS EARLY NEXT WEEK. RAIN
CHANCES WILL ALSO INCREASE THROUGH THE WEEKEND WITH SCATTERED TO
NUMEROUS SHOWERS AND THUNDERSTORMS DURING THE MORNING HOURS. A FEW
WATERSPOUTS WILL BE POSSIBLE EACH MORNING. /13
