Area Forecast Discussion
National Weather Service Melbourne FL
402 PM EDT Thu Jul 14 2022

.DISCUSSION...

Now thru tonight...Scattered thunderstorms have developed along
the Treasure Coast and Lake Okeechobee region this afternoon,
following the westward progression of the Atlantic sea breeze. For
now, this is where much of the activity is focused, though a few
showers are trying to develop farther north in western Brevard and
eastern Osceola counties. A gradual increase in storm coverage is
expected across interior locations, especially from Lake
Okeechobee to Orlando and Leesburg over the next several hours,
as the west and east coast sea breezes collide. 500mb temperatures
of -8C to -9C, DCAPE around 1000+ J/kg, and PW of 1.8"+ are some
of the ingredients supporting the threat for strong thunderstorms
this evening. The strongest activity will be capable of hail,
strong winds up to 55 mph, torrential rainfall, and frequent
lightning strikes. A Marginal Risk now encompasses much of east
central Florida for the potential of a few strong to severe storms
through tonight. By midnight, rain and storms will be winding
down, leaving behind partly cloudy conditions.

Friday-Sunday...With the Atlantic mid level ridge broken down and
an approaching upper level low from the Bahamas, an east-
southeasterly flow regime will quickly set up across east central
Florida. Storm initiation may occur a bit faster on Friday as the
Atlantic sea breeze pushes inland once again. Similar to today,
the highest coverage is expected over the interior, west of I-95
on Friday. Weak troughing will interact with the decaying upper
level low on Saturday and Sunday, when models continue to
indicate the highest chance for widespread storms. Heavy rainfall
over locations that are already saturated may lead to minor,
localized flooding this weekend. In addition, a severe storm or
two with hail and gusty winds cannot be ruled out.

Daytime temperatures are forecast to reach the upper 80s and low
90s, due to the added cloud cover and rain chances. Muggy
conditions will persist each night with lows in the 70s.

Monday-Thursday (modified previous)...A weak mid-level ridge
builds over FL to start next week and is forecast to bring some
drier air aloft over FL. At the surface, the Atlantic high will
build westward as its ridge axis redevelops over southern FL
peninsula. As a result, the low level flow veers southwest on
Monday, keeping high rain chances for ECFL (60-70pct) as the main
sea breeze collision occurs on our side of the peninsula. However,
from Tuesday onward rain chances are forecast to return to normal
mid-summer values of 40-50pct as the surface ridge axis settles
over Central FL. The main storm threats will continue to be
frequent lightning strikes, gusty winds, and torrential downpours.

Afternoon temperatures will steadily rise during the week,
reaching the low 90s along the coast and mid 90s inland. At night,
conditions remain muggy and warm with temps in the mid to upper
70s.

&&

.AVIATION...

VFR conditions prevailing outside of convection through the period.
Scattered to numerous showers and storms expected into the evening
hours, as the sea breezes collide over the interior of the
peninsula. VCTS lingering along the Treasure Coast through around 21-
22Z, before convection pushes inland. TEMPO groups have been
included for the interior terminals, where the highest confidence in
CIG/VIS reductions due to storms exists. A few storms could be strong
to marginally severe, with gusts up to around 45-50kts. Activity is
expected to linger through the evening hours again, tapering off by
around 2Z. SE flow this afternoon becoming light overnight.

&&

.MARINE...

Tonight...SSE winds around 15 kts will gradually decrease
overnight and become more SE. Seas 2 ft near shore and 3 ft
offshore will continue, except where locally higher near
thunderstorms.

Friday-Monday (previous)...The axis of the Atlantic surface ridge
is forecast to shift north of Central FL this weekend. This will
cause mostly E/ESE winds around 10 knots on Friday to veer
southeast on Saturday, then south on Sunday. Winds could increase
up to 15-17 knots Saturday night into Sunday. Scattered showers
and lightning storms are forecast over the local waters on Friday,
then storms become widespread over the weekend as a mid to upper-
level low moves over FL. Frequent lightning strikes and wind
gusts at or above 35 knots will pose a threat to mariners each
day. Storm activity is expected to redevelop over the offshore
waters each night.

The Atlantic high pressure will rebuild over the western Atlantic on
Monday, as its ridge axis redevelops over southern FL peninsula. The
resulting southwest winds mean another afternoon/evening of numerous
offshore moving thunderstorms along the Central FL Atlantic coast.

Seas 2-3 feet Friday and Saturday will build to 3-4 feet nearshore
and 4-5 feet offshore on Sunday, before dropping back to 3-4 feet on
Monday.

THIS HAZARDOUS WEATHER OUTLOOK IS FOR EAST CENTRAL FLORIDA.

.DAY ONE...THIS AFTERNOON AND TONIGHT.

.THUNDERSTORM IMPACT...
Scattered to locally numerous showers and lightning storms will
move toward the north or northeast at around 10 mph across east
central Florida this afternoon and evening. The highest coverage
will be over inland locations. A few storms will become strong to
potentially severe as they interact with the sea breezes and
other outflow boundaries, producing frequent lightning strikes,
strong wind gusts up to 55 mph, and locally heavy rainfall. Move
indoors to safety at the first sign of threatening skies or if
you hear thunder.

.FLOOD IMPACT...
Locally heavy rainfall is possible today, especially with slow
storm motions of 5 to 10 mph. A quick 1 to 2 inches of rain in an
hour with locally higher amounts of 3 or more inches may cause
local road, urban, and poor drainage flooding.

.EXCESSIVE HEAT IMPACT...
Hot and humid conditions will continue across the region today,
with highs in the low to mid 90s and peak afternoon heat index
values around 102 to 107. If outdoors today, make sure that you
stay hydrated and take plenty of breaks in air conditioned spaces.
Also, never leave a child or pet unattended in a vehicle.

.RIP CURRENT IMPACT...
There is a Moderate risk of life-threatening rip currents at all
east central Florida beaches today. To reduce your risk of getting
caught in the seaward pull of a rip current, always swim near a
lifeguard and never enter the ocean alone.

.MARINE THUNDERSTORM GUST IMPACT...
A few stronger storms may be capable of producing wind gusts to
35 to 45 knots through the afternoon and early evening hours as
they move north to northwest around 5 to 10 knots over inland
lakes.

.DAYS TWO THROUGH SEVEN...FRIDAY THROUGH WEDNESDAY.
Scattered to locally numerous showers and lightning storms are
forecast through this weekend and into early next week with the
highest chances across the interior. The main threats from any
stronger storms will be frequent lightning, as well as gusty
winds, and torrential downpours.

A moderate risk of dangerous rip currents is expected to continue
through late week and into the upcoming weekend.

.SPOTTER INFORMATION STATEMENT...
Formal activation of SKYWARN spotter networks is not expected to be
needed today. However, please report any rainfall amounts of 3
inches or greater to the National Weather Service office in
Melbourne.
