DISCUSSION
ISSUED AT 1212 PM CDT MON JUL 14 2025
AFTER SOME EARLY MORNING CONVECTION PRIMARILY NORTH OF THE I-30
CORRIDOR, RADAR ACTIVITY HAS DIMINISHED SOMEWHAT THROUGH THE EARLY
AFTERNOON HOURS. HOWEVER, NEW CONVECTIVE DEVELOPMENT IS BEGINNING
TO EMERGE ACROSS PORTIONS OF THE FORECAST AREA. WHILE SHORT-TERM
MODEL GUIDANCE HAS STRUGGLED WITH ACCURATELY CAPTURING THESE DAILY
DIURNAL STORMS, THE GENERAL CONSENSUS POINTS TO AN UPTICK IN
CONVECTIVE ACTIVITY LATER THIS AFTERNOON.
GIVEN THE COMBINATION OF EARLIER RAINFALL AND THE POTENTIAL FOR
TRAINING THUNDERSTORMS THIS AFTERNOON ACROSS NORTHEAST TEXAS AND
SOUTHEAST OKLAHOMA, A FLOOD WATCH HAS BEEN ISSUED FOR RED RIVER
AND MCCURTAIN COUNTIES. THOUGH SOME MODEL UNCERTAINTY REMAINS,
PARTICULARLY REGARDING STORM PLACEMENT AND INTENSITY, RECENT
MOISTURE INCREASES OVER THE REGION SUPPORT THE POTENTIAL FOR
LOCALIZED FLOODING. IN ADDITION, WE ARE MONITORING A SURGE OF SEA
BREEZE CONVECTION CURRENTLY LOCATED JUST SOUTH OF THE REGION IN
SOUTHERN LOUISIANA, WHICH COULD MOVE INTO OUR SOUTHERN ZONES LATER
TODAY.
TODAY IS LIKELY TO BE THE “COOLEST” DAY OF THE WEEK, WITH HIGH
TEMPERATURES RANGING FROM THE MID 80S TO MID 90S. UNFORTUNATELY, A
WARMING TREND IS ANTICIPATED THROUGH MIDWEEK, WITH DAYTIME HIGHS
CLIMBING STEADILY. HEAT ADVISORY CRITERIA MAY BE APPROACHED OR MET
IN SOME LOCATIONS AS EARLY AS TUESDAY. WHILE COORDINATION WITH
NEIGHBORING OFFICES LED TO A DECISION TO HOLD OFF ON ISSUANCE FOR
NOW, FUTURE FORECAST PACKAGES MAY INCLUDE HEAT HEADLINES PENDING
UPDATED GUIDANCE.
LASTLY, ATTENTION WILL SHIFT TOWARD THE GULF LATER THIS WEEK, AS
FORECAST MODELS CONTINUE TO SUGGEST THE POSSIBILITY OF TROPICAL
DEVELOPMENT. CURRENT TRENDS FAVOR A SYSTEM TRACKING BENEATH THE
RIDGE AND APPROACHING SOUTHERN OR SOUTHEASTERN LOUISIANA BY LATE
THURSDAY OR FRIDAY. CONFIDENCE IN SPECIFIC DETAILS REMAINS LOW AT
THIS TIME, BUT RESIDENTS ARE ENCOURAGED TO MONITOR UPDATES IN THE
COMING DAYS AS FORECAST CLARITY IMPROVES.
