DISCUSSION
ISSUED AT 120 PM EDT MON SEP 14 2026
A FEW SHOWERS CONTINUE TO DEVELOP ALONG THE COAST THIS AFTERNOON.
WITH PLENTY OF MOISTURE IN PLACE (THIS MORNING'S SOUNDING LOGGED
A 2.4" PWAT), STORM COVERAGE WILL EXPAND INLAND ALONG CONVERGING
SEA BREEZE AND OUTFLOW BOUNDARIES. LATER IN THE EVENING SHOWERS
AND STORMS COULD DRIFT BACK TOWARDS THE WEST COAST. MAIN HAZARDS
TODAY WILL BE HEAVY DOWNPOURS LEADING TO LOCALIZED FLOODING,
FREQUENT LIGHTNING, AND STRONG GUSTY WINDS. QUIET CONDITIONS
RETURN OVERNIGHT.
FOR TUESDAY, THE UPPER LEVEL RIDGE SHIFTS A LITTLE FURTHER NORTH
WHICH WILL REINFORCE A MORE EASTERLY FLOW OVER THE AREA. THIS WILL
MEAN CONVECTION DEVELOPING INLAND IN THE AFTERNOON TOMORROW, THEN
MOVING TOWARDS THE WEST COAST LATER IN THE EVENING. BY WEDNESDAY DRY
AIR ALOFT AND AT THE SURFACE WILL MOVE OVER MOST OF FL AHEAD OF AN
APPROACHING UPPER LEVEL LOW, LIMITING RAIN CHANCES, ESPECIALLY
NORTH OF I4. THE PRESSURE GRADIENT WILL ALSO BEGIN TO TIGHTEN UP
BETWEEN THE UPPER LEVEL RIDGE AND UPPER LEVEL LOW, INCREASING THE
NE WINDS. IN FACT WITH THE LOWER DEW POINTS, AND BREEZY NORTHEAST
WINDS, CONDITIONS WILL FEEL SLIGHTLY LESS SUMMERLIKE WEDNESDAY
AFTERNOON AND THURSDAY MORNING. HOWEVER, THE SLIGHT HINT AT FALL
QUICKLY FADES BACK INTO SUMMER LIKE CONDITIONS BY THE END OF THE
WEEK AS THE UPPER LEVEL LOW CONTINUES WEST INTO THE GULF, WRAPPING
MOISTURE BACK OVER THE AREA BY THE WEEKEND.
AVIATION
(18Z TAFS)
ISSUED AT 120 PM EDT MON SEP 14 2026
VFR CONDITIONS EXPECTED THROUGH THE PERIOD WITH THE ONLY
EXCEPTION BEING SHOWERS AND STORMS THAT DEVELOP AND MOVE NEAR OR
OVER TERMINALS. PASSING SHOWERS/STORMS COULD DROP CEILINGS AND
VISIBILITIES BELOW VFR FOR A SHORT PERIOD OF TIME. STORMS THAT
DEVELOP INLAND THIS AFTERNOON HAVE THE POTENTIAL TO DRIFT BACK
TOWARDS THE COAST LATER THIS EVENING.
MARINE
ISSUED AT 120 PM EDT MON SEP 14 2026
MAIN MARINE HAZARDS TO BEGIN THE WEEK WILL BE STORMS THAT DEVELOP OR
MOVE OVER THE WATERS. HOWEVER, BY MID WEEK, MARINE CONDITIONS
DETERIORATE AS THE PRESSURE GRADIENT TIGHTENS, INCREASING THE NE
WINDS, LIKELY TO ADVISORY LEVELS THROUGH EARLY FRIDAY.
FIRE WEATHER
ISSUED AT 120 PM EDT MON SEP 14 2026
FIRE WEATHER CONCERNS REMAIN LOW THROUGH THE PERIOD AS PLENTY OF
MOISTURE LINGERS OVER THE AREA.
