KEY MESSAGES
ISSUED AT 322 PM EDT SUN AUG 23 2026
- DAILY CHANCES OF SHOWERS AND STORMS WILL CONTINUE FOR THE NEXT
SEVERAL DAYS. OVERALL, RAIN CHANCES ARE LOWEST FOR TODAY, THEN
INCREASE THROUGH THE WORKWEEK. THE STRONGEST STORMS ARE EXPECTED
TO PRODUCE WIND GUSTS OF 40-60 MPH, FREQUENT LIGHTNING, AND
LOCALLY HEAVY RAIN. AN SPC MARGINAL RISK OF SEVERE STORMS IS IN
EFFECT THROUGH TUESDAY.
- ANOTHER HEAT ADVISORY MAY BE NEEDED FOR MONDAY ACROSS OUR
FLORIDA COUNTIES.
SHORT TERM
(THIS EVENING THROUGH MONDAY)
ISSUED AT 322 PM EDT SUN AUG 23 2026
AN SPC MARGINAL RISK (LEVEL 1 OF 5) FOR SEVERE STORMS REMAINS IN
EFFECT FOR THE REST OF TODAY INTO THE EVENING. ALTHOUGH A WATCH IS
NOT ANTICIPATED, LOW LEVEL LAPSE RATES AND PW WILL BE SUFFICIENT
IN A NORTHWEST FLOW REGIME TO ALLOW FOR WET MICROBURSTS TO
PRODUCE MARGINALLY DAMAGING WINDS IN ISOLATED STORMS THROUGH THIS
EVENING. A STALLED FRONT TO THE NORTH AND EXISTING OUTFLOW
BOUNDARIES ARE POTENTIAL TRIGGERING MECHANISMS.
COVERAGE OF STORMS WILL INCREASE ON MONDAY AND ANOTHER SPC
MARGINAL RISK FOR SEVERE STORMS IS ALREADY IN PLACE DUE TO THE
CONTINUED COMBINATION OF A NORTHWEST FLOW REGIME, DEEP MOISTURE
AND LOW LEVEL INSTABILITY. A WPC MARGINAL RISK (LEVEL 1 OF 4)
FOR EXCESSIVE RAINFALL IS ALSO IN PLACE.
UNCERTAINTY IN TIMING OF DEVELOPMENT OF CONVECTION AND ASSOCIATED
CLOUD COVER PRECLUDES THE ISSUANCE OF A HEAT ADVISORY AT THIS
TIME, ESPECIALLY CONSIDERING HOW THE CURRENT ADVISORY IS NOT
PANNING OUT. HOWEVER, FORECAST HEAT INDICES CURRENTLY SUPPORT ONE
FOR OUR FL COUNTIES AS WELL AS SOUTH GA FROM LOWNDES COUNTY EAST
ALONG THE FL BORDER TO LAKE SEMINOLE. THE OVERNIGHT SHIFT WILL
REASSESS.
LONG TERM
(MONDAY NIGHT THROUGH NEXT SATURDAY)
ISSUED AT 322 PM EDT SUN AUG 23 2026
TUESDAY AND WEDNESDAY WILL BE CARBON COPIES OF MONDAY WITH SPC AND
WPC MARGINAL RISKS IN PLACE. HEAT ADVISORY CRITERIA DOES NOT
APPEAR IN JEOPARDY. RAIN CHANCES WILL INCREASE FOR THURSDAY AND
FRIDAY AS A FRONT APPROACHES FROM THE NORTHWEST. NEAR NORMAL RAIN
CHANCES AND TEMPERATURES ARE FORECAST FOR THE WEEKEND.
AVIATION
(18Z TAFS)
ISSUED AT 322 PM EDT SUN AUG 23 2026
ISOLATED CHANCES FOR SHOWERS/THUNDERSTORMS THIS AFTERNOON, MAINLY
FOR THE DHN, ECP, AND TLH TERMINALS. OTHERWISE, VFR CONDITIONS
ARE EXPECTED TO PREVAIL THROUGH THE NIGHT. THERE IS POTENTIAL FOR
FOG DEVELOPMENT AROUND DAYBREAK FOR THE TLH, VLD, AND ABY
TERMINALS, AS NOTED BY A TEMPO GROUP, HOWEVER CONFIDENCE IS LOW TO
MEDIUM. SHOWERS AND THUNDERSTORMS RETURN TOMORROW AFTERNOON,
MAINLY INITIATING AFTER THE END OF THIS TAF PERIOD.
MARINE
ISSUED AT 322 PM EDT SUN AUG 23 2026
GENTLE TO OCCASIONALLY MODERATE SOUTHWESTERLY FLOW WILL CONTINUE
OVER THE WATERS FOR THE NEXT SEVERAL DAYS. SCATTERED SHOWERS AND
STORMS ARE POSSIBLE EACH DAY, MAINLY IN THE OVERNIGHT AND MORNING
HOURS, DECREASING IN THE AFTERNOON. THE MAIN EXCEPTION WILL BE FOR
ANY CLUSTERS OF STORMS THAT MOVE OFF THE COAST THIS WEEK DURING
THE LATE AFTERNOON OR EVENING HOURS. SEAS WILL REMAIN AROUND 1 TO
2 FEET.
FIRE WEATHER
ISSUED AT 322 PM EDT SUN AUG 23 2026
GENERALLY LIGHT WEST TO SOUTHWEST TRANSPORT WINDS WILL CONTINUE
THROUGH THE NEXT SEVERAL DAYS. DISPERSIONS WILL REMAIN GOOD OVERALL
EACH AFTERNOON. INCREASING COVERAGE OF STORMS ARE EXPECTED MONDAY
AND TUESDAY. GUSTY, ERRATIC WINDS AND DANGEROUS LIGHTNING STRIKES
WILL BE POSSIBLE.
HYDROLOGY
ISSUED AT 322 PM EDT SUN AUG 23 2026
THERE IS A WPC MARGINAL RISK (LEVEL 1 OF 4) FOR EXCESSIVE
RAINFALL ACROSS THE REGION FROM MONDAY THROUGH THURSDAY. STORMS
COULD PRODUCE LOCALLY HEAVY RAINFALL OVER THE NEXT SEVERAL DAYS.
IF THE STORMS ARE SLOW- MOVING, THEN THEY COULD PRODUCE SEVERAL
INCHES OF RAIN IN A SHORT PERIOD OF TIME. THIS WOULD LEAD TO SOME
NUISANCE TO ISOLATED FLASH FLOOD CONCERNS, PARTICULARLY IN LOW-
LYING OR POOR DRAINAGE AREAS. RIVER FLOODING IS NOT EXPECTED.
SPOTTER INFORMATION STATEMENT
WHILE CONVECTIVE COVERAGE IS NOT EXPECTED TO BE HIGH TODAY, SPOTTER
ACTIVATION IS REQUESTED AS STORMS THAT DO DEVELOP COULD BE
MARGINALLY SEVERE. SPOTTERS SHOULD SAFELY REPORT SIGNIFICANT
WEATHER CONDITIONS AND/OR DAMAGE BY CALLING THE OFFICE OR TWEETING
US @NWSTALLAHASSEE.
