DISCUSSION
(TODAY THROUGH SUNDAY)
ISSUED AT 1226 AM CDT MON JUL 6 2026
YESTERDAY EVENINGS STORMS MANAGED TO DUMP BETWEEN 1-4
INCHES OF RAIN ACROSS A SIZABLE SWATH OF THE REGION WHILE PRODUCING
GUSTY WINDS UP TO 50 MPH, COPIOUS LIGHTNING AND EVEN SOME SMALL
HAIL. A FEW THOUSAND PEOPLE REPORTEDLY LOST ELECTRICITY ACROSS
SOUTHWEST LOUISIANA, BUT THIS OFFICE RECEIVED NO REPORTS OF DAMAGE
BEYOND A FEW TREES DOWN.
UNFORTUNATELY, THE UPPER LEVEL TROUGH RESPONSIBLE FOR THE ABOVE
NORMAL PRECIPITATION REMAINS IN A QUASISTATIONARY STATE OVER
NORTHERN ARKANSAS THIS MORNING WITH LITTLE MOVEMENT EXPECTED TODAY
OR TUESDAY. THE RESULT WILL BE CONTINUED HIGHER THAN NORMAL
PROBABILITIES FOR STORMS BOTH THIS AFTERNOON AND TUESDAY AFTERNOON
AS DIURNAL HEATING PROVIDES INITIALIZATION. THE UPPER LEVEL SUPPORT
WILL LIKELY ALLOW STORMS TO LINGER LATER INTO THE EVENING, BUT AS
WAS THE CASE TONIGHT, ACTIVITY SHOULD BEGIN TO LOSE STEAM AROUND
SUNSET WITH ALL STORMS LARGELY ENDED BEFORE MIDNIGHT.
BY WEDNESDAY, SUBTROPICAL RIDGING WILL BEGIN BUILDING BACK ACROSS
THE NORTHERN GULF COAST GRADUALLY DISPLACING THE TROUGH WHICH WILL
THEN LIFT OFF TO THE NORTHEAST. SOME SLIGHTLY DRIER AIR ALOFT, THAT
SADLY WON'T MAKE ANY DIFFERENCE TO SURFACE DEWPOINTS, WILL ALSO WORK
IN FROM THE WEST. THIS WILL RESULT IN A SUBSTANTIAL DROP IN
AFTERNOON CONVECTION WEDNESDAY AND THURSDAY WITH ONLY A FEW
AFTERNOON THUNDERSTORMS EXPECTED. THE SUBSIDENCE KEEPING THE STORMS
AT BAY WILL ALSO LIMIT CLOUD COVER ALLOWING AFTERNOON HIGHS TO CLIMB
INTO THE MID 90S ACROSS CENTRAL LOUISIANA.
THERE'S BEEN A NOTABLE INCREASE IN POPS WITHIN THE NBM GUIDANCE THIS
WEEKEND LIKELY OWING TO THE LATEST ENSEMBLE RUNS LIFTING MUCH DEEPER
TROPICAL MOISTURE INTO THE REGION THIS WEEKEND. THIS GUIDANCE IS IN
GOOD AGREEMENT ON THIS MOISTURE AVAILABILITY OVERCOMING THE
WEAKENING, BUT STILL PRESENT, RIDGE ALOFT. THIS RUN TO RUN
INCONSISTENCY LOWERS CONFIDENCE IN POPS HEADING INTO NEXT WEEKEND,
BUT THIS TREND WILL CONTINUE TO BE MONITORED IN THE COMING DAYS.

FOR WEDNESDAY THROUGH FRIDAY.
