DISCUSSION
(THIS EVENING THROUGH NEXT THURSDAY)
ISSUED AT 1235 PM CDT FRI AUG 7 2026
IF YOU, LIKE ME, HAVE BEEN LEFT OUT OF THE RAIN OVER
THE LAST FEW DAYS AND ARE BEGINNING TO FEEL LIKE YOU LIVE IN A RAIN
BUBBLE , FRET NOT, FOR PRECIPITATION CHANCES WILL REMAIN IN THE 30-
60% CHANCE RANGE EACH AFTERNOON THROUGH AT LEAST TUESDAY. YOUR
BUBBLE WILL BURST EVENTUALLY.
THE REGION REMAINS EMBEDDED IN A NARROW WEAKNESS ALOFT BISECTING TWO
SPRAWLING RIDGES WITH ONE OVER THE FOUR CORNERS REGION AND THE
BERMUDA HIGH OVER THE WESTERN ATLANTIC. THIS WEAKNESS WILL CONTINUE
TO SUPPORT DAILY THUNDERSTORM DEVELOPMENT ONCE DAILY CONVECTIVE
TEMPS ARE EXCEEDED (PRESENTLY BEING MEASURED AROUND 90 DEGREES).
THESE WILL BE FURTHER ENHANCED DURING THE AFTERNOON BY THE INLAND
ADVANCING SEA BREEZE.
MID LEVEL MOISTURE IS EXPECTED TO INCREASE FURTHER SUNDAY AND MONDAY
AS A SLUG OF MOISTURE ASSOCIATED WITH A WEAK WAVE/INVERTED TROUGH
LIFTS NORTH OUT OF THE GULF. THIS WILL PUSH PRECIPITATION CHANCES
EVEN HIGHER (40-80%). THE INCREASE IN CLOUD COVER AND PRECIPITATION
WILL KEEP AFTERNOON HIGHS A FEW DEGREES COOLER IN THE UPPER 80S TO
LOWER 90S.
THE BERMUDA HIGH IS PROGGED TO BUILD WESTWARD ACROSS THE NORTHERN
GULF COAST WEDNESDAY WHICH WILL DROP PRECIPITATION CHANCES THROUGH
THE SECOND HALF OF NEXT WEEK.

INTERMITTENTLY IMPACTING THE TERMINALS. THESE STORMS WILL BE
CAPABLE OF BRIEF PERIODS OF VISIBILITY REDUCING HEAVY RAINFALL.

DISSIPATED BY 00Z. GUIDANCE IS ONCE AGAIN INDICATING THE POTENTIAL
FOR PATCHY, SHALLOW GROUND FOG EARLY SATURDAY MORNING. ANY FOG

LIGHT SOUTHEASTERLY WINDS AND LOW SEAS WILL CONTINUE
THROUGH NEXT WEEK AS A SURFACE HIGH PRESSURE SYSTEM RIDGES ACROSS
THE NORTHERN GULF. THERE WILL BE A DAILY CHANCE FOR SHOWERS AND
THUNDERSTORMS WITH THE BEST CHANCE CLOSER TO SHORE DURING THE

FIRE WEATHER
ISSUED AT 1235 PM CDT FRI AUG 7 2026
HIT OR MISS SHOWERS AND THUNDERSTORMS WILL BE POSSIBLE EACH
AFTERNOON THROUGH THE WEEKEND. WIDESPREAD SIGNIFICANT RAINFALL IS
NOT EXPECTED AND THIS WILL LIKELY ALLOW THE OVERALL ANTECEDENT
CONDITIONS TO BECOME DRIER WITH AN INCREASE IN THE KBDI. WITH LOW
LEVEL GULF MOISTURE FROM MAINLY SOUTHERLY WINDS, MINIMUM AFTERNOON
