DISCUSSION
ISSUED AT 1246 AM CDT THU OCT 1 2026
LOW-LEVEL SOUTHEASTERLY FLOW IS NOW ESTABLISHED ACROSS THE AREA,
TRANSPORTING GULF MOISTURE INLAND. AN UPPER LOW OVER THE SOUTHERN
PLAINS IS EXPECTED TO OPEN INTO A POSITIVELY TILTED TROUGH, WHILE
MID-LEVEL RIDGING BUILDS OVER THE SOUTHEAST. THIS WILL PROMOTE
INCREASING SOUTHEASTERLY FLOW ALOFT WHICH WILL HELP DEEPEN MOISTURE
ACROSS THE AREA. THIS MOISTURE RETURN WILL LEAD TO AN UPTICK IN
SHOWER AND THUNDERSTORM ACTIVITY TODAY, BEGINNING OFFSHORE AND ALONG
THE COAST THIS MORNING BEFORE SHIFTING INLAND BY AFTERNOON. COVERAGE
TODAY LOOKS GENERALLY SCATTERED (40-50% POPS) WITH LOWER COVERAGE
NORTH OF HIGHWAY 84. ANY STORMS MAY PRODUCE BRIEF HEAVY DOWNPOURS.
HIGHS WILL REMAIN ABOVE AVERAGE, CLIMBING INTO THE UPPER 80S TO LOW
90S.
THE MAIN STORY REMAINS THE HEAVY RAINFALL AND FLOOD THREAT
DEVELOPING FRIDAY AND CONTINUING THROUGH THE WEEKEND. AS THE
POSITIVELY TILTED UPPER TROUGH WEAKENS, DEEP TROPICAL MOISTURE IS
EXPECTED TO BEGIN POOLING AHEAD OF A SLOW-MOVING FRONT APPROACHING
FROM THE NORTHWEST. LOW-LEVEL CONVERGENCE ALONG A BROAD INVERTED
SURFACE TROUGH EXTENDING SOUTHWEST TO NORTHEAST ACROSS THE NORTHERN
GULF COAST WILL LEAD TO MULTIPLE ROUNDS OF HEAVY RAINFALL, WITH THE
SATURDAY AND SUNDAY BEING THE WETTEST DAYS FOR OUR AREA. FRIDAY'S
ROUND OF SHOWERS AND STORMS WILL LIKELY A BIT MORE BRIEF, BUT
LOCALLY HEAVY RAINFALL WILL STILL BE POSSIBLE AS PWATS SURGE TO
AROUND 2.3 INCHES BY AFTERNOON.
PWAT VALUES THEN APPROACH 2.4-2.5 INCHES FOR SATURDAY AND SUNDAY,
PLACING THEM ABOVE THE 99TH PERCENTILE FOR EARLY OCTOBER
CLIMATOLOGY. THIS ENVIRONMENT WILL SUPPORT EFFICIENT WARM-RAIN
PROCESSES AND LOCALLY INTENSE RAINFALL RATES. THE PRIMARY CONCERN IS
FOR MULTIPLE ROUNDS OF WIDESPREAD RAIN WITH EMBEDDED CONVECTION THAT
COULD TRAIN OVER THE SAME AREAS. WHILE THE TIMING AND LOCATION OF
THE HEAVIEST RAIN REMAINS UNCERTAIN, CURRENT FORECAST TOTALS FROM
FRIDAY THROUGH SUNDAY RANGE FROM 3-6 INCHES ACROSS THE SOUTHERN HALF
OF THE AREA, WITH A GENERAL 2-3 INCHES OVER THE INTERIOR. LOCALIZED
TOTALS OF 6-9 INCHES CANNOT BE RULED OUT NEAR THE COAST IF TRAINING
CONVECTION SETS UP. THIS COULD LEAD TO FLASH FLOODING, ESPECIALLY
FOR URBAN AND POOR-DRAINAGE AREAS. THE WPC HAS OUTLINED A SLIGHT
RISK (LEVEL 2 OUT OF 4) OF EXCESSIVE RAINFALL FOR SATURDAY AND
SUNDAY TO REFLECT THIS THREAT.
THE COLD FRONT WILL LIKELY PUSH THROUGH THE AREA BETWEEN LATE SUNDAY
AND EARLY NEXT WEEK, BUT UNCERTAINTY IS HIGH REGARDING HOW FAST THE
FRONT PUSHES OFFSHORE AND HOW FAR OFFSHORE IT WILL GET BEFORE
STALLING. THIS WOULD HAVE IMPLICATIONS ON RAIN CHANCES FOR NEXT
WEEK. REGARDLESS, PERSISTENT CLOUDS, RAIN, AND THE EXPECTED FRONTAL
PASSAGE WILL HOLD DAYTIME TEMPERATURES BELOW NORMAL THIS WEEKEND AND
BEYOND. HIGHS OVER THE WEEKEND ARE CURRENTLY FORECAST IN THE LOW TO
MID 80S, THROUGH SOME LOCATIONS MAY STRUGGLE TO RISE OUT OF THE 70S.
AT THE BEACHES, MODERATE ONSHORE FLOW WILL MAINTAIN A HIGH RISK OF
LIFE-THREATENING RIP CURRENTS TODAY THROUGH SUNDAY, DECREASING TO A
MODERATE RISK FOR MONDAY. JGC/98

(06Z TAFS)
ISSUED AT 1246 AM CDT THU OCT 1 2026
EXPECT PREVAILING VFR CONDITIONS FOR EARLY THIS MORNING. WILL BEGIN
TO SEE ISOLATED -SHRA ACROSS MAINLY MARINE WATERS, BECOMING MORE
NUMEROUS AROUND/AFTER DAYBREAK AND THRU MID-MORNING, MOVING INLAND
LATE MORNING INTO THE AFTERNOON. HAVE INTRODUCED BEST
TIMING/COVERAGE FOR PROB30'S FOR AREA TAF SITES BUT GENERALLY EXPECT
PASSING SHOWERS AT ANY POINT DURING THE DAY TODAY THROUGH THE
EVENING HOURS. MAIN IMPACTS WILL BE BRIEF REDUCTIONS IN FLIGHT
CATEGORIES FROM PERIODIC REDUCED VIS/CIGS BUT EXPECTING VFR OUTSIDE
OF ANY SHRA ACTIVITY. KLG
