A CLOSED UPPER-LEVEL LOW CENTERED OVER NORTH GEORGIA WILL CONTINUE
TO WEAKEN WHILE LIFTING NORTHWARD TODAY, EVENTUALLY BECOMING
ABSORBED INTO THE NORTHERN STREAM BY LATE TONIGHT. THIS WILL LEAVE
THE AREA UNDER A WEAK STEERING FLOW REGIME TODAY AS WE ARE
SANDWICHED BETWEEN THE SUBTROPICAL HIGH OFF THE EAST COAST AND THE
MONSOON RIDGE OVER THE DESERT SOUTHWEST. THIS PATTERN WILL ALLOW THE
SEA BREEZE TO PUSH FARTHER INLAND THIS AFTERNOON, BRINGING AN
INCREASE IN LOW-LEVEL MOISTURE. ISOLATED TO SCATTERED POPS (15-35%)
ARE FORECAST GENERALLY ALONG AND JUST NORTH OF THE I-10 CORRIDOR,
WHERE SEA BREEZE CONVERGENCE IS MOST LIKELY TO LEAD TO CONVECTIVE
INITIATION. THE SUBSIDENCE INVERSION AROUND 700 MB THAT SUBDUED ANY
DEEP CONVECTION OVER THE LAST TWO DAYS WILL BEGIN TO WEAKEN,
POTENTIALLY ALLOWING FOR A FEW THUNDERSTORMS THIS AFTERNOON. WITH
LINGERING DRY AIR ABOVE 700 MB AND DCAPE VALUES APPROACHING 1500
J/KG IN SPOTS, ANY THUNDERSTORMS THAT CAN MANAGE TO DEVELOP MAY
PRODUCE LOCALIZED STRONG DOWNBURST WINDS. HIGH TEMPERATURES WILL
REACH THE LOW TO MID 90S TODAY, WITH AN INCREASE IN HUMIDITY
BRINGING HEAT INDEX VALUES BACK INTO THE TRIPLE DIGITS (100-104
RANGE) IN SOME SPOTS THIS AFTERNOON, ESPECIALLY ACROSS SOUTHERN
PORTIONS OF THE AREA.
THURSDAY THROUGH SATURDAY, A SOUTHEASTERLY LOW-LEVEL FLOW REGIME
BECOMES ESTABLISHED AS THE SUBTROPICAL HIGH EXPANDS WESTWARD INTO
THE SOUTHEAST STATES. THIS WILL CONTINUE TO TRANSPORT ADDITIONAL
MOISTURE NORTHWARD WHILE ALLOWING THE SEA BREEZE TO ADVANCE INLAND
EACH AFTERNOON. THE MID-LEVEL CAPPING INVERSION CONTINUES TO
LIFT/WEAKEN THURSDAY AND SHOULD ERODE COMPLETELY BY FRIDAY,
SUPPORTING GREATER LIGHTNING POTENTIAL WITH ANY AFTERNOON
CONVECTION. RAIN CHANCES REMAIN GENERALLY IN THE 20-40% RANGE EACH
DAY, ALTHOUGH GUIDANCE IS INCONSISTENT ON WHERE THE GREATEST
COVERAGE WILL DEVELOP EACH DAY DUE TO PERIODIC BANDS OF HIGHER AND
LOWER PWATS PUSHING THROUGH. PEAK AFTERNOON HEAT INDICES WILL
CONTINUE TRENDING UPWARD, GENERALLY RANGING FROM 100-107 DEGREES
STARTING THURSDAY, AND POTENTIALLY REACHING 108-110 IN A FEW
SPOTS BY SATURDAY.
SUNDAY INTO EARLY NEXT WEEK, ENSEMBLE GUIDANCE INDICATES DEEPER
TROPICAL MOISTURE SURGING IN FROM THE SOUTHEAST WITH MORE WIDESPREAD
PWATS OVER 2 INCHES. THIS SHOULD SUPPORT AN UPTICK IN CONVECTIVE
COVERAGE, WITH POPS INCREASING INTO THE 40-60% RANGE FOR SUNDAY AND
MONDAY FOR MOST AREAS. RAIN CHANCES MAY BEGIN TO DECREASE BY TUESDAY
AS THE MAIN MOISTURE PLUME EXITS THE AREA, LEAVING A MORE TYPICAL
SUMMERTIME PATTERN IN ITS WAKE. HEAT INDICES WILL LIKELY REMAIN IN
THE 100-107 RANGE.
BEACH FORECAST... A LOW RISK OF RIP CURRENTS EXISTS AT AREA BEACHES
TODAY AND THURSDAY. AS ONSHORE FLOW STRENGTHENS LATE IN THE WEEK, A
MODERATE RISK OF RIP CURRENTS IS EXPECTED TO DEVELOP FRIDAY INTO THE
WEEKEND. JGC/98

ISSUED AT 1254 AM CDT WED AUG 5 2026
EXPECT VFR CONDITIONS FOR ALL AREA TERMINALS OVERNIGHT
INTO THE MORNING HOURS. WILL MONITOR AN INCREASE IN SCT TSRA/SHRA
TOMORROW AFTERNOON, FOCUSED MAINLY ALONG THE COAST FROM THE
SEABREEZE BOUNDARY. ANY INDIVIDUAL SHOWER/STORM WILL BE CAPABLE OF
PRODUCING LOCALIZED GUSTY, ERRATIC DOWNBURST WINDS, TEMPORARY
FLIGHT CATEGORY REDUCTIONS BY REDUCED VIS/CIGS, BUT EXPECT VFR
OUTSIDE OF ANY SCT TSRA/SHRA ACTIVITY THEN BECOMING PREVAILING
CLEAR/CALM AFTER SUNSET. KLG

GENERAL WESTERLY WINDS BECOME SOUTHWESTERLY THIS AFTERNOON WITH
A SOUTHEASTERLY FLOW DEVELOPING ON THURSDAY. AN EASTERLY TO
SOUTHEASTERLY FLOW DEVELOPS BY FRIDAY THEN BECOMES PREDOMINATELY
