DISCUSSION
ISSUED AT 256 AM EDT SAT JUL 25 2026
WEAK SURFACE HIGH PRESSURE IS RIDGING FROM THE ATLANTIC ACROSS
NORTHERN FLORIDA TODAY, KEEPING LIGHT WINDS AND HOT TEMPERATURES IN
PLACE. MOISTURE WILL CONTINUE TO FILL INTO THE AREA, LEADING TO
SCATTERED TO NUMEROUS SHOWERS AND STORMS ACROSS MOST OF THE AREA.
THE HIGHEST RAIN CHANCES WILL GENERALLY BE OVER THE INTERIOR, AS
WINDS WILL QUICKLY TURN TO WESTERLY THIS AFTERNOON AND CLEAR OUT THE
IMMEDIATE COAST. WITH AFTERNOON TEMPERATURES IN THE MID 90S AND DEW
POINTS IN THE MID TO UPPER 70S, HEAT INDEX VALUES ARE FORECAST TO
TOP OUT AROUND 108-109 OVER PARTS OF THE NATURE COAST TODAY, AND
A HEAT ADVISORY HAS BEEN ISSUED FROM NOON TO 7 PM FOR LEVY,
CITRUS, HERNANDO AND SUMTER COUNTIES. FARTHER TO THE SOUTH, HEAT
INDEX VALUES ARE MAINLY EXPECTED TO PEAK AROUND 102-107, ALTHOUGH
A FEW ISOLATED LOCATIONS MAY SEE HIGHER VALUES.
ON SUNDAY, THE SURFACE RIDGE WILL SHIFT SOUTHEAST INTO THE ATLANTIC
AS A COLD FRONT STALLS OUT NORTH OF FLORIDA. THIS WILL SETUP
GENERALLY WESTERLY FLOW THAT WILL HOLD THROUGH THE REST OF THE WEEK.
UNDER THIS PATTERN, A FEW SHOWERS OR STORMS WILL DEVELOP OVER THE
EASTERN GULF DURING THE LATE NIGHT HOURS AND COULD SHIFT ONSHORE
THROUGHOUT THE MORNING, THEN SCATTERED TO NUMEROUS THUNDERSTORMS
WILL DEVELOP EACH AFTERNOON OVER THE FLORIDA PENINSULA WITH THE
HIGHEST RAIN CHANCES OVER THE INTERIOR AS THE WEST COAST SEA
BREEZE PUSHES INLAND. THE WESTERLY FLOW WILL ALSO HELP TO MODERATE
AFTERNOON TEMPERATURES BACK DOWN TO NEAR NORMAL FOR LATE JULY.

CONDITIONS TO RETURN BY AROUND 00-03Z THIS EVENING.
