Area forecast discussion, Aug 2, 3:34 PM EDT, 59 minutes before
AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MIAMI FL
334 PM EDT SUN AUG 2 2015

.DISCUSSION...
GENERALLY LIGHTER SURFACE FLOW HAS ALLOWED A MORE ORGANIZED EAST
COAST SEA BREEZE TO DEVELOP. AS A RESULT...SCATTERED TO NUMEROUS
SHOWERS AND THUNDERSTORMS HAVE DEVELOPED ALONG ALL OF THE EAST COAST
METRO AREAS EARLY THIS AFTERNOON SPREADING ACROSS THE INTERIOR
WITH INTERACTION FROM THE GULF BREEZE. A FEW STRONG STORMS WILL
CONTINUE TO BE POSSIBLE THROUGH THE AFTERNOON WHERE CONVERGENCE
IS HEIGHTENED. 12Z MFL SOUNDING CONTINUES TO SHOW FAIRLY DRY MID
LEVELS WHICH HAS CONTRIBUTED TO THE WIND GUST POTENTIAL THAT HAS
BEEN PREVALENT OVER THE LAST FEW DAYS. GUSTY WINDS WILL CONTINUE
TO BE THE MAIN THREAT FOR THE REMAINDER OF THE AFTERNOON AND
EVENING ALONG WITH FREQUENT LIGHTNING AND POSSIBLY SMALL HAIL.
HRRR AND OTHER HI-RES MODEL GUIDANCE KEEPS THE MAJORITY OF THE
CONVECTION ACROSS THE INTERIOR AND EAST COAST THROUGH THE EVENING
WITH ACTIVITY WEAKENING AFTER SUNDOWN WITH HEATING LOSS.

MID LEVEL TROUGH/DEEP MOISTURE AXIS WILL REMAIN POSITIONED ACROSS
THE NORTHERN HALF OF THE FLORIDA PENINSULA THROUGH MONDAY. THIS WILL
HELP MAINTAIN A RATHER UNSETTLED WEATHER PATTERN ACROSS SOUTH
FLORIDA THROUGH THE FIRST PART OF THE WEEK WITH CONTINUED WEAK
SOUTHWEST STEERING FLOW. WEAKER FLOW WILL ALLOW SEA BREEZES AT BOTH
COASTS TO BECOME WELL ESTABLISHED KEEPING THE MAJORITY OF AFTERNOON
AND EARLY EVENING CONVECTION ACROSS THE INTERIOR.

LOWER H5 HEIGHTS ACROSS CUBA ARE THEN EXPECTED TO MOVE TO THE WEST
ALLOWING STRONGER RIDGING TO BUILD ACROSS THE WESTERN ATLANTIC INTO
THE MID TO LATE WEEK PERIOD. MODELS ARE A BIT MORE AGGRESSIVE IN
BRINGING IN A CONSIDERABLY DRIER (SAHARAN DUST) AIR MASS BY THURSDAY
AND LINGERING THROUGH THE END OF THE WEEK. IN ADDITION TO BRINGING A
RETURN TO A MORE EASTERLY FLOW REGIME...THIS RIDGING AND ASSOCIATED
DRIER AIR WILL HELP TO REDUCE OVERALL AFTERNOON SHOWER AND
THUNDERSTORM COVERAGE FOR THE LATTER PORTION OF THE WEEK AND INTO
THE WEEKEND.

&&

.AVIATION...
SHOWERS AND THUNDERSTORMS WILL CONTINUE TO DEVELOP ALONG THE EAST
COAST SEA BREEZE AS IT MOVES SLOWLY WEST INTO THE INTERIOR AREAS.
THEREFORE...THE VCTS WILL REMAIN IN PLACE FOR THE EAST COAST TAF
SITES ALONG WITH A TEMPO GROUP FOR KPBI AND KFXE TAF SITES THIS
AFTERNOON. THE WEATHER SHOULD BECOME DRY AFTER 00Z TONIGHT FOR THE
EAST COAST TAF SITES. THE WINDS WILL ALSO BE SOUTH TO SOUTHEAST
AT 10 TO 15 KNOTS OUTSIDE OF ANY SHOWERS OR THUNDERSTORMS...BUT
COULD GET UP TO 35 KNOTS WITH ANY STORM THAT DOES MOVE THROUGH
THE TAF SITES OF FXE AND KPBI ALONG WITH MVFR CONDITIONS IN THE
CEILING AND VIS.

KAPF TAF SITE WILL CONTINUE TO SEE WEST WINDS OF AROUND 10 KNOTS
THIS AFTERNOON BEFORE GOING LIGHT AND VARIABLE TONIGHT. THE SHOWER
AND THUNDERSTORM ACTIVITY SHOULD REMAIN EAST OF THE KAPF TAF SITE
THIS AFTERNOON...SO KAPF WILL REMAIN DRY THROUGH TONIGHT. THE
CEILING AND VIS WILL ALSO REMAIN IN THE VFR CATEGORY THROUGH
TONIGHT.

&&

.MARINE...
SOUTHEASTERLY TO EASTERLY SURFACE WINDS AVERAGING AROUND 10 KNOTS
SHOULD PREVAIL ACROSS THE ATLANTIC WATERS INTO NEXT WEEK WITH
SEAS AROUND 2 FEET OR LESS. WINDS ARE EXPECTED TO DECREASE ACROSS
THE GULF WATERS AND BECOME MOSTLY LIGHT AND VARIABLE. CHANCES FOR
SHOWERS AND THUNDERSTORMS ARE POSSIBLE EACH DAY AND NIGHT ALONG
THE ATLANTIC AND GULF WATERS THROUGH MAINLY THE FIRST HALF OF THE
UPCOMING WEEK.
