957 AM EDT FRI MAY 20 2016

.DISCUSSION...

...ISOLATED STRONG-SEVERE STORMS THIS AFTERNOON...

Today-Tonight...Radar and lightning data show weakening of lead
convective system moving along the north Gulf coast, but expect that
there will be an outflow boundary associated with it that reaches
our northern sections this afternoon.  Morning soundings show mid
level temps similar to yesterday (minus 9 degrees at 500mb), but the
models show a vort max approaching during peak heating with slight
cooling aloft.

The HRRR model shows the west coast sea breeze becoming active with
convection early-mid afternoon while much less forms on the east
coast sea breeze. This looks realistic since the morning Canaveral
sounding had a little lower precipitable water.  A collision of the
east/west boundaries is indicated farther inland today due to
earlier onset of the east coast sea breeze, but steering level winds
will push the convection back to the coast. With the added
convergence from the outflow boundary, northern sections should have
the greatest coverage through late afternoon/early evening, then the
activity should propagate to the south half through late evening.

Planning no significant changes to the forecast which is already
advertising likely PoPs for much of the area.

With the vort max and larger scale outflow boundary added to the
typical multiple afternoon boundary interactions, expect storms to
be a little stronger than the past few days.  Local damaging wind
gusts seem possible along with frequent lightning strikes.
Additionally, stronger and slower moving storms will be capable of
dumping 3-4 inches of rain again. This would lead to more
significant standing water and flooding problems, especially along
the Treasure Coast.

&&

.AVIATION...
VFR until about 18z, then MVFR to IFR conditions will occur in
scattered to numerous storms.  Have not included tempo groups yet in
the TAFs, but right now would expect them about 18-21z for the
interior terminals, 20-23z KDAB-KTIX and 21-24z from KMLB-KSUA.

&&

.MARINE...
Today-Tonight...Weak high pressure ridge extending from the Atlantic
into the Gulf of Mexico will provide a light/gentle south/southwest
breeze. Seas 1-2 feet nearshore and 2 to 3 feet well offshore. The
main mariner hazard will be offshore moving storms, some
necessitating Special Marine Warnings this afternoon and evening.

THIS HAZARDOUS WEATHER OUTLOOK IS FOR EAST CENTRAL FLORIDA.

.DAY ONE...THIS AFTERNOON AND TONIGHT.

.THUNDERSTORM IMPACT...
AN APPROACHING OUTFLOW BOUNDARY AHEAD OF A WEAKENING BAND OF
SHOWERS AND STORMS WILL COMBINE WITH SEA BREEZE COLLISIONS AND A
PASSING DISTURBANCE ALOFT TO GENERATE SCATTERED TO NUMEROUS
LIGHTNING STORMS THIS AFTERNOON AND EVENING. STORMS WILL INITIALLY
DEVELOP ACROSS LAKE COUNTY AND THROUGH THE I-4 CORRIDOR IN THE
EARLY AFTERNOON...BECOMING NUMEROUS TOWARD LATE AFTERNOON AND THE
EARLY EVENING AS THEY TRACK EAST UP TO 15 TO 20 MPH AND INTERACT
WITH THE EAST COAST SEA BREEZE.

THE PRIMARY HAZARDS WILL BE STRONG TO ISOLATED SEVERE WIND GUSTS
UP TO 50 TO 60 MPH...FREQUENT CLOUD TO GROUND LIGHTNING STRIKES
AND LOCALLY HEAVY RAINFALL.

.FLOOD IMPACT...
THUNDERSTORMS DEVELOPING LATER THIS AFTERNOON WILL HAVE THE
POTENTIAL TO PRODUCE LOCALLY HEAVY RAINFALL AMOUNTS AROUND TWO TO
THREE INCHES WITH THE STRONGEST STORMS. SOME OF THE STORMS WILL
LIKELY AFFECT AREAS NEAR THE EAST COAST FROM VERO BEACH SOUTH
THAT HAVE ALREADY EXPERIENCED HEAVY RAIN OVER THE PAST FEW DAYS.
THIS WILL ELEVATE THE RISK FOR ADDITIONAL FLOODING IN LOW-LYING
AND POOR DRAINAGE AREAS ALONG THE TREASURE COAST.

.MARINE THUNDERSTORM GUST IMPACT...
SCATTERED STRONG THUNDERSTORMS MOVING EASTWARD UP TO 15 TO 20 MPH
WILL HAVE THE POTENTIAL TO PRODUCE WIND GUSTS IN EXCESS OF 35 MPH
OVER INLAND LAKES AND AS THEY MOVE OFFSHORE LATER IN THE
AFTERNOON.

.DAYS TWO THROUGH SEVEN...SATURDAY THROUGH THURSDAY.
ADEQUATE MOISTURE AHEAD OF A FRONTAL BOUNDARY WILL SUPPORT
SCATTERED TO NUMEROUS SHOWERS AND STORMS SATURDAY. SOME OF THE
STORMS MAY BECOME STRONG WITH GUSTY WINDS AND LOCALLY HEAVY
RAINFALL WITH THE POTENTIAL FOR MINOR FLOODING IN AREAS THAT HAVE
EXPERIENCED HEAVY RAIN OVER THE LAST SEVERAL DAYS. A FRONT WILL
MOVE THROUGH THE AREA LATE SUNDAY AND BRING DRY WEATHER EARLY NEXT
WEEK.

.SPOTTER INFORMATION STATEMENT...
SPOTTERS ARE REQUESTED TO MONITOR THE WEATHER AND SELF ACTIVATE
IF NEEDED. RAINFALL SPOTTERS SHOULD REPORT RAINFALL AMOUNTS OVER
TWO INCHES TO THE NATIONAL WEATHER SERVICE IN MELBOURNE.

AT 1157 AM EDT...DOPPLER RADAR WAS TRACKING A LINE OF STRONG
THUNDERSTORMS ALONG A LINE EXTENDING FROM FORT MCCOY TO NEAR
WEIRSDALE TO NEAR ST. LEO...AND MOVING EAST AT 20 TO 25 MPH.

WINDS IN EXCESS OF 45 MPH WILL BE POSSIBLE WITH THESE STORMS AND
WITH ANY OUTFLOW BOUNDARY THAT MOVES OUT AHEAD OF THIS LINE.

LOCATIONS IMPACTED INCLUDE...

LIMBS...CAUSE POWER OUTAGES OR CAPSIZE SMALL BOATS. HEAVY RAINFALL
WILL TEMPORARILY REDUCE VISIBILITY. SEEK SHELTER INDOORS UNTIL THE
STORM PASSES.

BOATERS SHOULD BE AWARE THAT STRONG WIND GUSTS SOMETIMES OCCUR WELL
AWAY FROM THE HEAVY RAIN AND LIGHTNING ASSOCIATED WITH STORMS.

HEAVY RAINFALL IS ALSO OCCURRING WITH THESE STORMS...WHICH WILL
REDUCE VISIBILITY AND MAY LEAD TO TEMPORARY FLOODING OF LOW LYING AND
POOR DRAINAGE AREAS. DO NOT DRIVE YOUR VEHICLE THROUGH FLOODED
ROADWAYS.

IF ON OR NEAR LAKES...GET OUT OF THE WATER AND MOVE INDOORS OR
INSIDE A VEHICLE. REMEMBER...LIGHTNING CAN STRIKE OUT TO 15 MILES
FROM THE PARENT THUNDERSTORM. IF YOU CAN HEAR THUNDER...YOU ARE
CLOSE ENOUGH TO BE STRUCK BY LIGHTNING. MOVE TO SAFE SHELTER NOW.
DO NOT BE CAUGHT ON THE WATER IN A THUNDERSTORM.
