WITH DAILY AFTERNOON THUNDERSTORMS, AFTERNOON HIGHS IN THE LOW
TO MID 90S AND MAX HEAT INDICES FROM 98 TO 107 DEGREES.
- SOMEWHAT HIGHER PRECIPITATION CHANCES SUNDAY IN RESPONSE TO
HIGHER TROPICAL MOISTURE SURGING INTO THE REGION.

INCREASING TEMPERATURES A COUPLE DEGREES AND SLIGHTLY
DECREASING RAIN CHANCES.
SHORT TERM
(TODAY THROUGH MONDAY NIGHT)
ISSUED AT 257 AM CDT SAT JUN 28 2025
THE TYPICALLY WEAK PRESSURE GRADIENT THROUGH THE COLUMN WILL
RESULT IN ANOTHER DAY OF DIURNALLY DRIVEN AFTERNOON CONVECTION
THIS AFTERNOON WITH THE HIGHEST PROBABILITIES SURROUNDING THE
ATCHAFALAYA BASIN. COLLIDING OUTFLOW BOUNDARIES AND STORMS WITH
STRONGER UPDRAFTS WILL AGAIN HAVE THE POTENTIAL TO PRODUCE
TROPICAL FUNNEL CLOUDS. CONVECTION WILL AGAIN WANE AROUND SUNSET
WITH ACTIVITY LARGELY MOVING OFFSHORE OVERNIGHT.
GUIDANCE HAS BEEN VERY CONSISTENT IN DEPICTING SUBSTANTIALLY
HIGHER POPS SUNDAY FROM LATE MORNING THROUGH THE EVENING. THE
CULPRIT OF THIS EXPANDED COVERAGE IS A DEEPER SLUG OF TROPICAL
MOISTURE LIFTING INTO THE REGION OUT OF THE GULF. THIS MOISTURE
LOOKS TO BE LOOSELY CORRELATED TO THE TROPICAL DISTURBANCE NHC IS
MONITORING FOR TROPICAL DEVELOPMENT IN THE BAY OF CAMPECHE WHICH
WILL EVENTUALLY MOVE INTO MEXICO BY EARLY NEXT WEEK. THE
INCREASED COVERAGE AND EFFICIENT RAIN PRODUCING STORMS COULD
PRODUCE SOME NUISANCE STREET FLOODING IN A FEW LOCATIONS
ESPECIALLY THOSE THAT SEE MORE THAN ONE STORM. STORMS SHOULD AGAIN
DISSIPATE AROUND OR SHORTLY AFTER SUNSET SUNDAY EVENING.
THE MOISTURE SURGE WILL CONTINUE LIFTING INLAND BY SUNDAY NIGHT
WITH AFTERNOON POPS RETURNING TO MORE NORMAL 40-60% MONDAY
AFTERNOON.

LONG TERM
(TUESDAY THROUGH SATURDAY)
ISSUED AT 257 AM CDT SAT JUN 28 2025
UPPER LEVEL RIDGING BEGINS TO BUILD ACROSS THE DEEP SOUTH TUESDAY
AND REMAIN QUASISTATIONARY THROUGH THE END OF THE WEEK. THE
SUBSIDENCE ALOFT WILL LIKELY LIMIT AFTERNOON CONVECTION ALTHOUGH
GUIDANCE IS IN GOOD AGREEMENT ON SOME ACTIVITY STILL DEVELOPING
DURING PEAK HEATING. FEWER STORMS AND LESS CLOUD COVER WILL
LIKELY PUSH TEMPERATURES A COUPLE DEGREES HIGHER THAN THE 92-95
THAT HAS BEEN PRETTY CONSISTENT THE LAST COUPLE OF WEEKS AND MAX
HEAT INDICES WILL FOLLOW SUIT. NBM KEEPS HEAT INDICES BELOW HEAT
ADVISORY CRITERIA FOR NOW, BUT THIS WILL CONTINUE TO BE MONITORED
THROUGH NEXT WEEK.
