AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MIAMI FL
204 PM EDT THU AUG 7 2014

.SHORT TERM (TONIGHT-SATURDAY NIGHT)...
CURRENTLY, DEEP LAYER RIDGE STRETCHES ACROSS SOUTH FLORIDA WITH A
VERY WEAK STEERING FLOW AT NEARLY CALM. THIS WILL ALLOW FOR THE SEA
BREEZES TO DEVELOP ALONG BOTH COASTS AND THEN ONLY VERY SLOWLY
MOVING INLAND WITH THUNDERSTORMS FORMING ALONG THE BOUNDARIES.
THESE STORMS COULD BASICALLY JUST ABOUT ANYWHERE THIS AFTERNOON
AND MOVE VERY LITTLE. THE PRIMARY THREAT WILL BE HEAVY RAINFALL
WITH POSSIBLE MINOR URBAN STREET FLOODING AND OF COURSE FREQUENT
LIGHTNING STRIKES. THE ATMOSPHERE IS VERY MOIST WITH PWAT AT JUST
OVER TWO INCHES WITH A VERY UNSTABLE ENVIRONMENT AS WELL WITH MID
LEVEL LAPSE RATES AT 6.5C/KM.

THE RIDGE WILL BEGIN TO LIFT NORTH OF THE LAKE BY FRIDAY INTO THE
WEEKEND WITH A SOUTHEAST TO SOUTH STEERING FLOW DEVELOPING. THIS
WILL RESULT IN ACTIVITY SHIFTING TO MORE THE INTERIOR AND LAKE
REGION. HOWEVER, THE FLOW WILL NOT BE NECESSARILY THAT STRONG SO
DEVELOPMENT COULD EASILY OCCUR ACROSS THE SUBURBS OF BOTH COASTAL
METRO AREAS BEFORE PUSHING INLAND LATER IN THE AFTERNOONS.
FORECAST SOUNDINGS ARE CURRENTLY SHOWING SOME SLIGHT DRYING ALOFT
WITH PWAT DROPPING TO NEAR 1.7 INCHES. HOWEVER, INSTABILITY WILL
STILL DOMINATE SO NUMEROUS STORMS ACROSS THE INTERIOR STILL APPEAR
LIKELY.

.LONG TERM (SUNDAY-THURSDAY)...
LITTLE CHANGES ARE EXPECTED IN THE LONG RANGE FORECAST WITH DEEP
EAST TO SOUTHEAST FLOW CONTINUING INTO THE MIDDLE OF NEXT WEEK. THE
PWAT WILL MAINTAIN VALUES OF AROUND 1.7 INCHES AND FLOW WILL STILL
NOT BE VERY STRONG SO SUBURBS COULD CONTINUE TO RECEIVE INITIAL
DEVELOPMENT WITH ACTIVITY SHIFTING TO THE INTERIOR AND LAKE REGIONS
IN THE AFTERNOONS. A LARGE MID LEVEL TROUGH IS EXPECTED TO MOVE INTO
NEW ENGLAND LATE IN THE WEEK. THIS WILL SHIFT THE STEERING FLOW FROM
THE SOUTHWEST TO NORTHEAST AND ACTIVITY BY THE END OF THE WEEK MAY
RETURN TO THE INTERIOR AND EAST COAST.

&&

.AVIATION...
THE WEST AND EAST COAST SEA BREEZES ARE BEGINNING TO DEVELOP AND ARE
NOT EXPECTED TO PENETRATE VERY FAR INLAND. THIS WILL KEEP
SHOWER/THUNDERSTORM DEVELOPMENT ALONG THE COASTAL ZONE AND IN THE
VICINITY OF THE TERMINALS WITH VCTS ASSIGNED TO ALL TERMINALS AT
18Z. THERE COULD BE BRIEF PERIODS OF IFR CONDITIONS INTO THE EARLY
EVENING HOURS WITH THE OCCURRENCE OF SHOWERS/THUNDERSTORMS. WEAK AND
VARIABLE WINDS ARE EXPECTED ACROSS THE REGION TONIGHT WITH SOME
UNCERTAINTY IN THE WIND FORECAST.

&&

.MARINE...
RATHER BENIGN CONDITIONS WILL CONTINUE WITH A LIGHT EAST TO
SOUTHEAST WIND AT LESS THAN 15 KNOTS THROUGH THE PERIOD WITH SEAS
OF LESS THAN 4 FEET.
