.DISCUSSION...

Currently-Tonight...Outflow from storms across Volusia County is
moving quickly inland, with the remainder of the east coast sea
breeze still steadily pushing westward, west of I-95. Greatest
storm coverage through mid to late afternoon will be along and
ahead of this boundary across the interior, with scattered to
numerous showers and storms developing. Some light rainfall and
occasional lightning strikes will be possible with debris cloud
cover that shifts east from these storms back toward the coast.
However, threat for any stronger storms producing frequent
lightning strikes, gusty winds and torrential downpours will
remain across inland areas. Past sunset, convection will shift
toward west central FL with any lingering rainfall from weakening
storms diminishing. Deep E/SE flow will keep a chance for onshore
moving showers and potentially a storm or two, mainly along the
coast overnight. Overnight lows will range from the low to mid
70s.

Friday-Sunday...Weak low/inverted trough aloft across Florida
Friday will shift west of the area into the weekend, while ridge
axis at the surface remains north of the region. This allow a
deepening onshore flow to prevail that will strengthen slightly
through the period. Deep moisture (PW values around 1.8-2.0")
persists through Saturday, with the potential for some mid level
drier air decreasing overall moisture into Sunday. However, still
should see scattered to numerous showers and storms develop each
day, with greatest coverage continuing to be focused across the
interior and west central Florida due to easterly steering winds.

Rain chances range from 50 percent along much of the coast,
except 60 percent along the southern Treasure Coast, and up to
60-70 percent across the interior Friday and Saturday. Rain
chances then decrease to 40-50 percent across much of the area on
Sunday. A slight warming trend is expected through the weekend,
as highs return to the upper 80s to low 90s each afternoon with
overnight lows in the low to mid 70s each night.

Monday-Wednesday...(Modified Previous) A weak upper-level low
over the west Atlantic, east of the Bahamas, into early next week
will push west-northwest toward the southeast U.S. through
Wednesday. Easterly flow will continue through the time period,
with moisture once again increasing and leading to above normal
rain chances across the area. PoPs will reside around 60 to 70
percent each day, with the greatest threat for afternoon lightning
storms continuing to be to the west of I-95. Afternoon highs will
be in the upper 80s, reaching 90 degrees in some places, with
cloudy conditions expected each afternoon. Cloud cover is forecast
to decrease overnight with overnight lows in the low to mid 70s.

&&

.AVIATION...VFR conditions prevailing outside of convection
through the TAF period. Weak E-SE flow is taking the east coast
sea breeze inland, with scattered to numerous showers and a few
thunderstorms propagating along the boundary. High thunderstorm
coverage is expected at inland terminals from 20-22z, so TEMPO
groups for TSRA remain at SFB, MCO, ISM, and LEE. Model guidance
has been indicating rounds of showers and and possibly a
thunderstorm or two overnight and into the early morning, so
several terminals maintain VCSH through this period. Numerous
showers and scattered thunderstorms are once again expected
tomorrow afternoon.

&&

.MARINE...

Tonight...Isolated to scattered showers and storms will continue
to be possible over the waters into tonight. E/SE winds up to
10-15 knots will occur with seas building to 3-4 feet nearshore,
up to 4-5 feet offshore.

Friday-Saturday...East to southeast winds persist across the
waters up to 10-15 knots, with seas up to 3-5 feet Friday and
around 3-4 feet Saturday. Scattered showers will storms will be
able to develop over the waters, moving westward and onshore each
day.

Sunday-Monday...(Modified Previous Discussion) The Atlantic ridge
axis remains north of the local area, continuing the easterly
flow through the time period. Rain chances will remain near to
above normal with scattered showers and lightning storms being
possible across the waters each day and pushing onshore, with
continuing showers and isolated storms remaining possible
overnight. Winds will decrease slightly, to around 10-12 KT. Seas
up to 5ft offshore Sunday morning, fall to 4 feet or less through
the remainder of the weekend into early next week.

THIS HAZARDOUS WEATHER OUTLOOK IS FOR EAST CENTRAL FLORIDA.

.DAY ONE...TODAY AND TONIGHT.

.THUNDERSTORM IMPACT...
Scattered to numerous lightning storms will once again develop
this afternoon across east-central Florida. The highest chances
for storms will be west of Interstate 95. Frequent lightning
strikes, torrential downpours, and gusty winds up to 45 mph are
possible with any storm today.

Additional lightning storms will develop along the coast and over
the local Atlantic waters late this evening into the overnight.

.FLOOD IMPACT...
Some locations west of Interstate 95 will receive 2 to 4 inches
of rain in a short duration this afternoon. This could result in
minor flooding of urban, low lying, and poor drainage areas.
Areas that received heavy rainfall yesterday are more prone to
flooding, including most of the Orlando Metro area, north to
DeLeon Springs, and west into Lake County.

.RIP CURRENT IMPACT...
There is a moderate risk of dangerous, life-threatening rip
currents at all central Florida Atlantic beaches today. Always
swim within sight of a lifeguard, and never enter the surf alone.

.MARINE THUNDERSTORM GUST IMPACT...
Lightning storms over the local waters today and tonight will be
capable of producing wind gusts up to 35 knots, in addition to
occasional to frequent lightning strikes.

.DAYS TWO THROUGH SEVEN...FRIDAY THROUGH WEDNESDAY.
Scattered to numerous afternoon showers and lightning storms are
forecast through the end of the week. Cloud-to-ground lightning
strikes torrential downpours leading to minor flooding, and gusty
winds will be the main threats with these storms.

The rip current risk will remain moderate through the weekend.

.SPOTTER INFORMATION STATEMENT...
Spotters should monitor the weather and self activate if needed,
especially if heavy rainfall produces local flooding.
