.DISCUSSION...

...A Few Strong to Marginally Severe Storms This Afternoon...
...Periods of Heavy Rainfall with Localized Flooding Possible This
Week...

Current-Tonight...Winds will continue to transition onshore as the
sea breeze ventures further inland this afternoon. Radar continues
to show increasing coverage and intensity of showers and isolated
lightning storms early this afternoon and expect this trend to
continue thru late afternoon and early evening; especially with
additional mesoscale boundary collisions and eventual larger sea
breeze collision across the interior. A few strong to marginally
severe storms will be possible. Latest 15Z KXMR sounding shows a
PWAT of 1.99 inches and a 500 mb temp of -9.3C.

We continue to keep lowest PoPs near 50pct along the immediate St.
Lucie/Martin coasts, trending up to 60-70pct from Indian River-
Brevard-Volusia counties. Interior locales are forecast for 80-
90pct, mainly for this afternoon thru sunset. Storm steering flow is
light W/NW, but may also see some erratic movement, especially from
stronger boundary collisions late today. Some activity will drift
back toward the coast. Strongest storm impacts continue to be
frequent lightning strikes, torrential rainfall leading to minor or
nuisance flooding, especially if multiple rounds are received, small
hail - up to quarter-size in a storm or two, and gusty winds of 40
to 55 mph - with a storm or two possibly severe with winds to
around 60 mph.

Convective activity will gradually diminish thru late evening, with
some overnight potential continuing across Volusia/north Brevard
counties and perhaps a bit further inland northward. Overnight lows
generally in the 60s to L70s.

Previous Extended Forecast Discussion Slightly Modified...

Tue...A weak frontal boundary will sag south into central FL.
Combined with deep moisture and upper support, numerous slow moving
storms will develop through the afternoon. Rain chances will remain
high, peaking at 70-90 percent from mid aftn to early evening. Temps
aloft will cool to -9C as upper trough deepens over the Deep South,
leading to some strong to marginally severe storms and more rounds
of heavy rain with frequent lightning. Will hold off on a Flood
Watch for now. Max temps will range from the lower 80s along the
Volusia coast to the mid and upper 80s elsewhere.

Extended...Weak low pressure is forecast to develop over or near the
central FL east coast Wed along the stalled frontal boundary and
lift slowly away from the area late week. Deepening upper trough
over the eastern US evolves into a cut-off upper low over the
Southeast US this weekend in an anomalous blocking pattern. Further
cooling aloft and sufficient moisture will maintain scattered to
numerous PoPs through Fri with stronger storms capable of gusty
winds, hail and heavy rain. This sure looks like a kickstart to the
wet season but occasionally there have been some false starts.

Some drier air is expected to push into the area this weekend which
will decrease rain chances 30-40 percent Sat and 20-30 percent
Sunday. Afternoon highs are forecast to remain in the low to mid 80s
Wed-Fri warming slightly this weekend as precip coverage decreases.
Overnight lows in the mid to upper 60s.

&&

.MARINE...
Issued at 250 PM EDT Mon May 22 2023

Afternoon-Tonight...Higher coverage of shower and storms developing
over the local waters through the day and tonight, especially
north of Sebastian Inlet. Onshore wind component becoming light
and variable again late this evening and overnight; especially
with disruptions from convection. Speeds generally 6-12 kts. Seas
building to 3-4 ft late today offshore and up to 5 ft well
offshore Volusia coast overnight. Winds/seas locally higher invof
of storms. Other storm threats include frequent cloud-to-water
lightning strikes, small hail, torrential downpours, and gusty
winds in excess of 35 kts. Some activity may be offshore moving.

Previous Extended Marine Forecast Discussion Slightly Modified...

Tue-Fri...Frontal boundary sags south across central FL Tue then
weak low pressure is forecast to develop over or near the FL east
coast along this stalled boundary Wed. Expect a high coverage of
rain/storms in this unsettled pattern. Storms will produce locally
higher winds and seas. The sfc low is forecast to move NE and away
from the area late week resulting in a north wind flow over the
local waters. Winds will start easterly Tue around 10 knots becoming
variable same speeds Wed then E-N winds will spread southward Thu
behind the departing low with speeds 10-15 knots. Boating conditions
should become poor to hazardous Thu night/early Fri esp in the Gulf
Stream as north winds increase near 15 knots. Seas 3-5 ft Tue
(especially north of Sebastian Inlet), and continuing to build to 6
ft Wed night-Thu offshore north of Sebastian Inlet, then 7 ft Thu
night offshore (north of the Cape), and finally 7-9 ft Fri-Fri night
over the offshore waters and possibly near shore Volusia.

THIS HAZARDOUS WEATHER OUTLOOK IS FOR EAST CENTRAL FLORIDA.

.DAY ONE...THIS AFTERNOON AND TONIGHT.

.THUNDERSTORM IMPACT...
A disturbance across the Southeast, an increase in moisture, along
with the east and west coast sea breezes, will spark numerous
showers and lightning storms today. The greatest chance for stronger
storms is this afternoon and early evening, first over interior of
east central Florida before potentially affecting coastal
communities this evening as some activity drifts back toward the
coast. Besides torrential rainfall and frequent cloud-to-ground
lightning strikes, a couple of the storms could become severe, with
wind gusts approaching 60 miles per hour. Small hail is in play and
a storm or two could contain hail to quarter-size.

.FLOOD IMPACT...
Where repeated rounds of thunderstorms occur, localized rain
amounts up to 4 inches in a short time are possible. This could
lead to flooding of low-lying areas. If you encounter flooding,
remember: turn around, don't drown.

.RIP CURRENT IMPACT...
A Moderate risk of life-threatening rip currents continues at all
central Florida Atlantic coast beaches. Check with your local
beach patrol for additional information about ocean hazards.
Remember to swim only within sight of a lifeguard, and never enter
the ocean alone.

.MARINE THUNDERSTORM GUST IMPACT...
Wind gusts over 35 knots from the strongest storms will affect
inland lakes, intracoastal waterways, and the near shore Atlantic
waters today.

.DAYS TWO THROUGH SEVEN...TUESDAY THROUGH SUNDAY.
A series of disturbances will keep central Florida weather unsettled
for much of the work-week. Copious amounts of moisture will remain
in place, and weak low pressure may form close to Florida by the
middle of the week. As a result, numerous showers and lightning
storms are forecast. The strongest storms will be capable of
producing frequent cloud-to-ground lightning strikes, gusty winds
from 40 to 50 mph, and hail to quarter-size.

Locations that see repeated rounds of heavy rain will experience
localized flooding this week.

A Moderate risk of dangerous rip currents is expected to continue at
all central Florida Atlantic beaches this week.

.SPOTTER INFORMATION STATEMENT...
Spotters should monitor the weather and self activate if needed.
