KEY MESSAGES
- A GENERAL WEAKNESS IN THE RIDGE ALOFT WILL REMAIN OVER THE
REGION INTO EARLY NEXT WEEK ALLOWING DAYTIME HEATING AND
SEABREEZE-DRIVEN SHOWERS AND STORMS EACH DAY.
- TYPICAL SUMMERTIME HOT CONDITIONS CAN BE EXPECTED THROUGH THE HOLIDAY
WEEKEND WITH THE HEAT RISK MAINLY AT MODERATE OR LEVEL 2 OF 4.
MAX AFTERNOON APPARENT TEMPERATURES OR THE HEAT INDEX WILL RANGE
FROM 100 TO 107 DEGREES DAILY.
- FOR THE FOURTH OF JULY HOLIDAY WEEKEND, BE MINDFUL OF THE DAILY
STORMS. HEAR THUNDER ROAR, THEN GO INDOORS. ALSO, TAKE IT EASY
IF OUTDOORS FROM THE HEAT, REMAIN HYDRATED AND TAKE FREQUENT
BREAKS IN THE SHADE OR IN AN AIR CONDITIONED PLACE. STORMS ARE
EXPECTED TO DISSIPATE BEFORE EVENING FIREWORK ACTIVITY.
DISCUSSION
(THIS AFTERNOON THROUGH NEXT WEDNESDAY)
ISSUED AT 1100 AM CDT THU JUL 2 2026
LITTLE CHANGE IN THE FORECAST OVER THIS PERIOD. A RETURN TO THE
TYPICAL DIURNAL PATTERN CAN BE ANTICIPATED AS HIGH PRESSURE BACKS
OFF GRADUALLY OVER THE PERIOD. DEEP MOISTURE IN PLACE WILL
INTERACT WITH DAILY DIURNAL HEATING TO BRING ABOUT SCATTERED
SHOWERS AND THUNDERSTORMS EACH AFTERNOON THROUGH THE START OF NEXT
WEEK.
HIGHS WILL PREVAIL NEAR CLIMO NORMALS AS TEMPS WARM INTO THE LOW
90S DAILY. HUMIDITY WILL RANGE IN THE 50 TO 60 PERCENT RANGE
DURING THE DAY WHICH SHOULD KEEP HEAT INDICES TO THE 100 TO 106 F
RANGE. THIS IS JUST UNDER HEAT ADVISORY CRITERIA, HOWEVER, HEAT
RISK IN THE LEVEL 2 OF 4 WILL PREVAIL. MEANING HEAT IMPACTS TO
THE BODY WILL BE POSSIBLE, PARTICULARLY FOR THOSE NOT ACCUSTOMED
TO THE HOT, HUMID OUTDOOR CONDITIONS.
FOR THOSE WITH INDEPENDENCE DAY PLANS, WE CONTINUE TO URGE HEAT
PREPARATIONS AND TO MONITOR FOR AFTERNOON STORMS. LIGHTNING CAN
OCCUR 10S OF MILES AWAY FROM STORMS, SO IF YOU CAN HEAR THUNDER,
MAKE SURE TO TAKE COVER UNTIL THE STORM HAS PASSED. STORM ACTIVITY
WILL TAMP DOWN WITH SUNDOWN AND THE LOSS OF DAYTIME HEATING, SO
HOPEFULLY FIREWORKS ACTIVITY WON'T BE TOO IMPACTED.
BE SAFE OUT THERE AS WE ALL CELEBRATE THE 250TH ANNIVERSARY OF OUR
NATION!

WEAKNESS OVERHEAD COMBINED WITH DEEP TROPICAL MOISTURE WILL RESULT
IN ANOTHER ROUND OF AFTERNOON SHOWERS AND THUNDERSTORMS. NOT
EXPECTING A VERY WIDESPREAD COVERAGE, JUST SCATTERED CONVECTION MOST
PRIMARILY ALONG THE SEABREEZE. WHERE THERE ARE STORMS, HEAVY
DOWNPOURS, LIGHTNING AND GUSTY WINDS ARE EXPECTED.
THIS WEAKNESS WILL ALSO RESULT IN VERY LITTLE FLOW AT THE SURFACE
AND LIGHT VARIABLE WINDS IN THE 5 TO 8 KNOT RANGE CAN BE
ANTICIPATED. AFTER SUNDOWN, WINDS WILL FALL TO CALM.
ANY LINGERING SHOWERS AND STORMS WILL DISSIPATE AFTER SUNDOWN AND
THE LOSS OF DAYTIME HEATING. AN AREA OF FOG DEVELOPED LAST NIGHT IN
RESPONSE TO THE RAINFALL RECEIVED TO THE REGION YESTERDAY.
ANOTHER ROUND OF PATCHY FOG CAN BE EXPECTED ALONG THE ATCHAFALAYA
BASIN THRU SUNRISE FRIDAY.

FIRE WEATHER
