Area Forecast Discussion
National Weather Service Melbourne FL

...A Nocturnal Tornado Threat Exists Late Tonight...

.UPDATE...
Issued at 1137 PM EDT Sat Apr 29 2023

Another wild day for most of east central Florida as afternoon-
evening thunderstorms brought gusty winds and hail once again,
especially in Brevard county where hail up to 2" were observed and
wind gusts up to 6 mph were recorded. Fortunately for the northern
interior, the Gulf MCV/MCS collapsed as it reached the west coast,
delivering just some light rain and a bit of gusty wind. Thing
have cleared out for the moment, but residents of east central
Florida should remain alert as another round is expected to arrive
early in the morning.

Strong to severe thunderstorms will develop ahead of an
approaching cool front, reaching Lake County by around 4 AM,
quickly pushing southeast through the morning, and departing south
of Stuart by around noon. An approaching mid-level shortwave will
provide large scale ascent, and the addition of a low level jet,
copious low and deep layer shear. This will allow storms to become
organized, producing strong winds around 50 mph and locally
damaging winds up to 70 mph, hail up to 1.25 inches, and possibly
a strong tornado or two this morning. Be sure to leave your phones
on tonight, and that they are able to receive Wireless Emergency
Alerts.

.MARINE...
Issued at 1137 PM EDT Sat Apr 29 2023

Tonight...Deteriorating boating conditions, becoming hazardous by
sunrise. Southerly winds quickly increase to 25-30 kts nearshore
and 30 to 35 kts offshore ahead of a cold front reaching the
northern Atlantic waters early Sunday morning. Gusts could reach
40-50 kts. Seas stay around 2-3 ft close to shore due to offshore
flow, but increase to 5-6 ft in the nearshore waters further from
the coast, and 7-8 ft with occasional seas up to 9 feet offshore
by morning. Strong to severe thunderstorms expected ahead of the
frontal boundary as it pushes through the local Atlantic waters.
Stronger storms could produce winds well in excess of 34 kts,
frequent cloud to water lightning, large hail, locally higher
seas, and possibly waterspouts.

&&

.AVIATION...
(00Z TAFS)
Issued at 1137 PM EDT Sat Apr 29 2023

VFR conditions through 08Z, then NUM-WIDE +TSRA ahead of a cool
front reaching KLEE around 08Z, working quickly SE through the
morning, and pushing south of KSUA ~16Z. MVFR-LIFR impacts with
wind gusts over 30 kts possible for 2-3 hours once convection
reaches each terminal. VFR conditions prevail once convection
clears. Gusty with winds SW-S 20G30KT Sunday.

&&

.PREV DISCUSSION...
Issued at 1137 PM EDT Sat Apr 29 2023

Sunday... One more day of unsettled weather in store for east
central Florida, as a "cool" front traverses east-southeast across
east central Florida. Resulting in scattered to numerous showers and
lightning storms out ahead of the frontal boundary early in the
morning through early afternoon. The storms are expected to develop
over the eastern Gulf of Mexico early Sunday morning, reaching the I-
4 corridor around sunrise and clearing the Treasure coast by early
afternoon. These storms will be accompanied by greater wind shear
and dynamic forcing, allowing for strong to severe storms to once
again be a concern.

The Storm Prediction Center (SPC) has east central Florida in a
"SLIGHT" risk for severe weather for Sunday. Forecast soundings
shows a favorable environment for stronger to severe storms, with
ample instability (MUCAPE 1000-1500 J/kg), sufficient shear (50-60kt
0-6km shear), 0-3km SRH as high as 200-300 m^2/s^2, cooler
temperatures aloft (500mb temperatures of -10 to -12 C), and steep
mid level lapse rates. This will result in any storms forming Sunday
to be capable of producing damaging wind gusts around 60-70mph, hail
around 1" in diameter, heavy rainfall (1-3" total), brief tornadoes,
and frequent lightning strikes. Rain chances will gradually diminish
from the northwest to southeast as the front sags southeast and
clears the Treasure Coast by Sunday afternoon with decreasing cloud
cover expected. Afternoon high temperatures are forecast to reach
the upper 70s to low 80s.

Monday-Friday...A dry airmass begins to settle into the area on
Monday as surface high pressure builds through mid week. PWATs will
generally remain between 0.5-1" before starting to increase on
Friday. No mentionable PoPs through the period. High temperatures
will be mostly in M80s on Monday. Winds veering to the NW on
Wednesday will keep highs in the L80 to the north of the I-4
corridor with M80s to the south. Temperatures will then climb into
the L90s by Friday with M/U80s along the coast.

THIS HAZARDOUS WEATHER OUTLOOK IS FOR EAST CENTRAL FLORIDA.

.DAY ONE...TONIGHT INTO EARLY SUNDAY.

.THUNDERSTORM IMPACT...
Another band of storms associated with an approaching cool front
is forecast to sweep east from the Gulf of Mexico. These storms
will have more wind shear and dynamic forcing to work with. As a
result, there is a threat for nocturnal tornadoes with these
storms as they push through the area between 4 AM and noon. Make
sure you have multiple ways to receive weather warnings and
consider keeping your phone on and charged tonight.

.MARINE THUNDERSTORM GUST IMPACT...
Storms early Sunday will be capable of producing wind gusts
greater than 35 knots, large hail, frequent cloud-to-water
lightning, and locally higher waves on inland lakes, the
Intracoastal Waterway, and nearshore Atlantic waters.

.WATERSPOUT IMPACT...
Storms containing brief funnel clouds or waterspouts will be
possible within coastal areas early Sunday as storms interact
with the east coast sea breeze then push offshore.

.WIND AND SEA IMPACT...
Boating conditions become hazardous. South winds will increase to
as high as 35 knots with gusts up to 50 kts, with seas building up
to 8 to 9 feet by morning.

.RIP CURRENT IMPACT...
A Moderate risk of dangerous rip currents continues at all central
Florida Atlantic beaches.

.DAYS TWO THROUGH SEVEN...SUNDAY THROUGH FRIDAY.
Potential for strong to severe storms will continue through early Sunday
as a frontal boundary sweeps through. The main threats will be
strong wind gusts, hail, and possible tornado or two.

There will be at least a Moderate risk of dangerous rip currents
through the weekend. Hazardous boating conditions are forecast to
develop on Sunday, as southwest winds increase up to 35 knots
with gusts as high as 50 knots.

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