- MORNING DENSE FOG POTENTIAL THROUGH WEDNESDAY
- NEAR RECORD HIGHS INLAND THROUGH WEDNESDAY
- EXTENDED DRY SPELL CONTINUES THROUGH WEDNESDAY. BE VERY CAUTIOUS
WITH OUTDOOR FIRES CHECK FOR LOCAL BURN BANS. SEVERE TO EXTREME
DROUGHT EXPANDING ACROSS INLAND AREAS
NEAR TERM /THROUGH MONDAY/
THIS AFTERNOON, WEAK FRONTAL BOUNDARY ACROSS THE CENTRAL PARTS
OF THE AREA WITH SUFFICIENT MOISTURE FOR PLENTY OF CUMULUS CLOUDS
OVER NORTHEAST FL. MULTIPLE RUNS OF THE HRRR AND OTHER GUIDANCE
SUGGEST ISOLATED TO POTENTIALLY SCATTERED SHOWERS FORMING OVER
INLAND NORTHEAST FL ALONG AND AHEAD OF THE FRONT, WITH MAIN FORCING
LOW LEVEL CONVERGENCE WITH A WEAK AREA OF LOW PRES FORMING AROUND
LAKE CITY. MODEL SOUNDING SHOWED MLCAPE OF ABOUT 1200 J/KG THIS
AFTERNOON, BUT GIVEN THE AMOUNT OF DRY AIR ALOFT AND RELATIVELY WEAK
DYNAMIC FORCING, CHANCE OF A THUNDERSTORMS SEEMS LESS THAN ABOUT 10
PERCENT. MAX TEMPS INTO THE UPPER 70S TO LOWER 80S TODAY WITH
POSSIBLE RECORD AT CRG WHERE THE CURRENT RECORD IS 83 IN 2013.
LOW LEVEL WINDS TURN TO THE NORTHEAST ALONG THE COAST THIS AFTERNOON
WHICH WILL LIKELY RE-PRIME PORTIONS OF THE AREA FOR MOISTURE AND
THEREBY POTENTIAL FOG DEVELOPMENT LATER TONIGHT.
FOR TONIGHT, THE FRONT WILL MOVE SOUTH OF THE AREA AND HIGH PRESSURE
WILL BUILD TO THE NORTH. WE SHOULD SEE THE SURFACE WINDS DECREASE
FROM THE NORTHEAST TO 5 MPH OR LESS. SKIES WILL BE MOSTLY CLEAR AND
WITH THE DRY AIR ALOFT AND THE LIGHT TO CALM WINDS, FOG POTENTIAL
WILL INCREASE AFTER MIDNIGHT. FOR THE INLAND AREAS, AT LEAST AREAS
OF FOG ARE EXPECTED THROUGH SUNRISE MONDAY MORNING, WITH DENSE FOG
ADVISORIES POSSIBLE ONCE AGAIN. LOW TEMPS IN THE LOWER 50S ACROSS
INLAND SE GA AND MID/UPPER 50S ACROSS INLAND NE FL AND LOWER 60S
ALONG THE ATLANTIC COASTAL AREAS.
SHORT TERM /MONDAY NIGHT THROUGH TUESDAY NIGHT/
HIGH PRESSURE BUILDS OVER THE EASTERN SEABOARD OF THE CONUS AT THE
START OF THE NEW WEEK AS THE FRONTAL BOUNDARY FROM SUNDAY WILL BE
SOUTH OF THE LOCAL AREA. NORTHEASTERLY FLOW DEVELOPS ACROSS COASTAL
LOCATIONS WITH AROUND 10 TO 15 MPH. ALONG INLAND LOCATIONS EASTERLY
FLOW WILL BE PRESENT WITH WINDS AROUND 5 TO 10 MPH, WITH DECREASING
WINDS THE FURTHER AWAY FROM THE EAST COAST. VERY LOW CHANCES OF
SHOWERS ACROSS NORTH CENTRAL FL THROUGH THE DAY AS DRY AIR CONTINUES
TO FILTER IN FROM THE NORTHWEST. DAYTIME HIGHS IN THE UPPER 70S TO
LOWER 80S, LOWER TEMPS ALONG COASTAL LOCATIONS IN THE MID 70S. BY
THE OVERNIGHT HOURS LOWS WILL DIP TO THE UPPER 50S ACROSS INLAND
LOCATIONS AND THE LOWER 60S ALONG THE COAST. SOME OFFSHORE SHOWERS
MAY BE POSSIBLE DURING THE OVERNIGHT HOURS ALONG THE FRONTAL
BOUNDARY.
BY TUESDAY, THE HIGH PRESSURE TO THE NORTH WILL BEGIN TO SHIFT
TOWARDS THE ATLANTIC AS ANOTHER FRONTAL BOUNDARY WILL BEGIN TO MOVE
TOWARDS THE SE CONUS, NEARING SE GA BY THE OVERNIGHT HOURS. THE
DEPARTING HIGH PRESSURE WILL BRING ABOUT A SHIFT IN THE WIND FLOW
FROM NORTHEASTERLY TO A MORE SOUTHEAST-SOUTHERLY FLOW AND THEN
FINALLY SOUTHWESTERLY BY TUESDAY NIGHT. A BIT WARMER TEMPERATURES ON
TUESDAY AS WINDS SHIFT TO BECOME SOUTHERLY. DAYTIME HIGHS IN THE
LOWER TO MID 80S OVER INLAND LOCATIONS WITH UPPER 70S TO LOWER 80S
ALONG THE COAST. OVERNIGHT LOWS WILL BE SIMILAR TO MONDAY NIGHT,
WITH UPPER 50S FOR INLAND LOCATIONS AND LOWER 60S ALONG THE COAST.
WEAKENING WINDS AND LOW LEVEL MOISTURE WILL LIKELY SEE FOG DEVELOP
OVER INLAND LOCATIONS DURING THE EARLY HOURS EACH MORNING. THE
DEVELOPING SOUTHWESTERLY FLOW TUESDAY EVENING WILL LIKELY BRING THE
HIGHER CHANCES OF FOG DEVELOPMENT OVER NE FL.
LONG TERM /WEDNESDAY THROUGH SUNDAY/
A COLD FRONT WILL APPROACH THE AREA BY WEDNESDAY. ISOLATED TO
SCATTERED SHOWERS AND ISOLATED STORMS MAY DEVELOP AHEAD AND ALONG
THE FRONT AS IT ENTERS SE GA AND TOWARDS THE FL/GA STATE LINE BY THE
AFTERNOON HOURS INTO EARLY EVENING HOURS. AS MUCH OF THE AREA WILL
STILL BE IN FRONT OF THE FRONT ON WEDNESDAY, DAYTIME HIGHS WILL
PRIMARILY BE IN THE LOWER TO MID 80S, WITH UPPER 70S ALONG FAR
INLAND SE GA. COME THURSDAY AND FRIDAY, TEMPERATURES WILL TOP OUT IN
THE 60S WITH COOLER TEMPERATURES ON FRIDAY AS A HIGH PRESSURE AND A
COLD, DRY AIR MASS BUILDS IN BEHIND THE FRONT. BREEZIER CONDITIONS
DEVELOP ON THURSDAY AND FRIDAY AS NORTHWESTERLY WINDS REACH AROUND
10 TO 15 MPH ACROSS INLAND LOCATIONS AND GUSTS UP TO 25-30 MPH OVER
THE LOCAL WATERS. OVERNIGHT LOWS WILL DIP TO NEAR FREEZING ACROSS
INLAND SE GA THURSDAY NIGHT, BUT FROST DEVELOPMENT WILL LIKELY BE
LIMITED DUE TO THE LIGHT BREEZE OVER THE AREA. OVERNIGHT LOWS WILL
'WARM' A BIT ON FRIDAY NIGHT, BUT STILL REMAIN IN THE UPPER 30S
ALONG INLAND SE GA AND THE 40S ALONG INLAND NE FL. WINDS WILL BEGIN
SHIFT TO BECOME NORTHEASTERLY TO EASTERLY BY THE UPCOMING WEEKEND
AS THE HIGH PRESSURE SHIFT AWAY TOWARDS THE ATLANTIC. DRY CONDITIONS
WILL CONTINUE INTO THE START OF THE UPCOMING WEEKEND.
AVIATION /00Z MONDAY THROUGH 00Z TUESDAY/
THE 00Z TAF PERIOD WILL BEGIN WILL VFR CONDITIONS WITH SCATTERED
CEILINGS NEAR 1.0 KFT AT SSI BRUSHING ONSHORE THROUGH 03Z AS WINDS
FROM THE NORTHEAST OFF THE WATERS BEHIND THE COLD FRONT MOVING INTO
NORTH CENTRAL FL SINKS SOUTHWARD. LATER TONIGHT, LOW STRATUS AND FOG
DEVELOPING INLAND FROM THE COAST AS WINDS FROM THE NORTHEAST SLACKEN
TO NEAR CALM BY 06Z AND UNDER CLEAR SKIES SUPPORT MVFR FOG/IFR
CEILINGS TO DEVELOP. THE LOW STRATUS AND FOG WILL LOWER BETWEEN 07-
09Z FROM IFR TO VLIFR LEVELS AT INLAND SITES VQQ, GNV, AND EVEN JAX,
THEN SHIFT TOWARDS THE COAST BY 09Z-10Z WHERE IFR/LIFR CEILINGS AND
FOG WILL BE MORE INTERMITTENT AS NORTHEAST WINDS CONTINUE OVERNIGHT
JUST UNDER 5 KNOTS.
THE FOG SHOULD BEGIN LIFTING INLAND TO MVFR LEVELS AFTER 13Z AND
RISE BACK TO VFR BY 15Z AT ALL SITES. HIGH PRESSURE TO THE NORTH
WILL SHIFT EASTWARD WITH WINDS TURNING MORE EASTERLY DURING IN THE
AFTERNOON 5-8 KNOTS INLAND/8-10 KNOTS COAST WITH SCATTERED HIGH THIN
CLOUDS PASSING IN FROM THE WEST AND FEW LOW/MID LEVEL CLOUDS NEAR
5.0 KFT.

PATCHY HIGH DAYTIME DISPERSIONS ALONG AND NORTH OF I-10 MONDAY
AFTERNOON...
AREAS OF HIGH DAYTIME DISPERSIONS ON WEDNESDAY...
CRITICALLY LOW MIN RH VALUES RESUME OVER INLAND AREAS THURSDAY
AND FRIDAY AFTERNOON...
COLD FRONT WILL CONTINUE TO PRESS TOWARDS NORTHEAST FLORIDA THIS
AFTERNOON WITH NORTHWEST WINDS 5-10 MPH AS HIGH PRESSURE BUILDS IN
FROM THE NORTHWEST. HIGH PRESSURE WILL BE NORTH OF THE AREA MONDAY
AND SHIFT OFF THE MID ATLANTIC COAST BY MONDAY EVENING, LEADING TO
THE NORTHEASTERLY WINDS TURNING EASTERLY BY THE AFTERNOON HOURS.
HIGH PRESSURE WILL EXIT NORTHEAST OF THE REGION TUESDAY WITH A WARM
FRONT LIFTING NORTH ACROSS THE AREA ALLOWING WINDS TO BECOME
SOUTHERLY, BUT NO RAIN EXPECTED. A COLD FRONT WILL APPROACH FROM THE
NORTHWEST ON TUESDAY NIGHT/WEDNESDAY MORNING AND THEN PUSH THROUGH
THE AREA LATE WEDNESDAY WITH INCREASING CHANCES FOR SHOWERS AND
ISOLATED T'STORMS OVER SOUTHEAST GA, BUT WITH SWIFT ENOUGH MOVEMENT
TO PREVENT A WETTING RAINFALL. INCREASING SOUTHWESTERLY SURFACE AND
TRANSPORT WINDS WILL PRODUCE AREAS OF HIGH DAYTIME DISPERSIONS
WEDNESDAY.
A MUCH DRIER AIRMASS ARRIVES FOR THE END OF THE WEEK AS STRONG HIGH
PRESSURE BUILDS IN FROM THE NORTHWEST THAT WILL PLACE CRITICALLY LOW
MIN RH VALUES OVER THE AREA THURSDAY AND FRIDAY.
FOG POTENTIAL AND OTHER REMARKS...AREAS OF DENSE FOG WILL DEVELOP
TONIGHT AWAY FROM THE COAST AS THE COLD FRONT SLOWLY SHIFTS SOUTH OF
THE AREA. PATCHY FOG WILL REMAIN POSSIBLE ACROSS NE FL BOTH TUESDAY
AND WEDNESDAY MORNINGS.
