What forecasters said that day

The local office's own words before this severe thunderstorm warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Melbourne, FL wrote its last area forecast discussion before this severe thunderstorm warning went out at Jun 9, 3:20 PM EDT, 21 minutes earlier.

Area forecast discussion, Jun 9, 3:20 PM EDT, 21 minutes before

Area Forecast Discussion
National Weather Service Melbourne FL
320 PM EDT Thu Jun 9 2022

.DISCUSSION...
Tonight and Friday...Anticipated area of concern continues to
shift southward of the Sanford to Clermont area, and storm
activity should focus south of Orlando toward the Space and
Treasure coasts the remainder of the afternoon into evening. Main
hazards wl be gusty winds to around 45mph, and locally heavy
rainfall-frequent lightning.

Activity should diminish by around 10 PM while continuing
offshore. Overnight low temperatures wl fall into the low to mid
70s.

Friday...A favorable setup for numerous storms to develop during the
aftn. Anticipated PWAT 1.7-1.8 inches coupled with favorable W-SW
flow wl favor the eastern portion of the peninsula for storm
movement and development. Rain amounts of one the two inches will
be possible areawide with local amounts of 3 to 4 inches possible,
esp along the coastal convergence zone. Main hazards will be
outflow winds, frequent lightning and standing water impeding
travel.

Weekend...Broadly cyclonic flow aloft over the eastern CONUS will
amplify during Sat, then begin evolution toward the US East coast
on Sunday. This wl lead to a favorable setup for deep convection
to develop daily across the peninsula. Will go with numerous
storms each day, while reserving the possibility of going a little
higher cvrg Sunday, depending on how progressive the Eastern wave
migrates further downstream. Suitable steering level winds out of
the SW should mitigate stationary rain producers, however multiple
waves of thunder wl have the potential to produce minor flooding
and standing water conds each day.

from prev disc...

Extended...Mid level ridging will build eastward from Texas which
may aid in returning PoPs to climo range of 30-50%. The surface
ridge axis will begin to drift back northward on Monday as the
stalled boundary lifts away from the area. This will lead to winds
backing to southerly and equally dominant east and west coast sea
breezes. Highest coverage of showers and storms will be across
the interior next week and with weak steering flow, higher rain
totals could aid in concerns for flooding. Temperatures hold
steady in the low/mid 90s leading to heat index readings over
100F; lows in the mid 70s.

&&

.AVIATION...Deeper westerly flow today, though still rather light.
The WCSB will be dominant and move across the peninsula quickly
today. Mid to late afternoon as convection moving west to east hits
a developing ECSB (pinned near coast) we may see a few strong,
pulse, lightning storms. Coverage seems greatest south of a KMCO-
KTIX line with highest focus near the Space/Treasure coasts late
today into early evening. Primary threats remain lightning strikes,
torrential rainfall, gusty downburst winds and perhaps some small
hail. Once activity moves off of the east coast, expect diminishing
trend after sunset and overnight as clouds thin. Light to calm winds
tonight. Deeper moisture on Fri with continued WRLY flow, possible
early initiation again, with some strong storms/higher overall
coverage areawide.

&&

.MARINE...
Tonight...Southwest winds 5 to 12 kts and 2-3 ft seas. Expect
locally higher winds and seas near offshore moving storms this
evening.

Friday-Sun...High rain cvrg during the period with scattered to
numerous lightning thunderstorms along the coast and moving
offshore from the mainland. Expect gusty winds and frequent
lightning over nearshore marine zones, and to some extent offshore
as well. West to southwest winds 8-15 knots. Seas remain 2-4 ft,
with locally higher winds and seas near stronger storms.

Extended...Wrn Atlc subtropical ridge wl become established over
the marine area early in the week. Generally favorable conds can
be expected with lower coverage of storms as well through at least
Tue.

THIS HAZARDOUS WEATHER OUTLOOK IS FOR EAST CENTRAL FLORIDA.

.DAY ONE...TODAY AND TONIGHT.

.THUNDERSTORM IMPACT...
Scattered lightning storms will push east across central Florida
with some increase in coverage, mainly south of a line from
Clermont to Orlando to Titusville. This activity is expected to
interact with the east coast sea, breeze pinned at the coast late
in the day. A few strong storms may result from this collision,
capable of producing wind gusts up to 50 mph and frequent
lightning. If thunder is heard, seek shelter in an enclosed
building or automobile. Picnic shelters, porches, golf carts and
dugouts offer no protection from the dangers of lightning.

.FLOOD IMPACT...
Storms along the coast this afternoon and early evening will be
capable of heavy rainfall, accumulating 1 to 2 inches in some
spots. This will cause temporary flooding of some roads and low
lying areas especially where recent heavy rains have occurred.

.RIP CURRENT IMPACT...
There is a Moderate Risk of rip currents at area beaches. Persons
should swim at a guarded beach and never enter the water alone.

.MARINE THUNDERSTORM GUST IMPACT...
Scattered lightning storms will push east across central Florida
and affect some inland lakes. An increase in storm coverage and
intensity will occur from mid to late afternoon they interact
with the east coast sea breeze. A few strong storms may cross the
intracoastal waters, barrier islands and over the nearshore
Atlantic waters containing wind gusts 35 knots or greater and
frequent lightning strikes.

.DAYS TWO THROUGH SEVEN...FRIDAY THROUGH WEDNESDAY.
Scattered afternoon thunderstorms are expected through the
weekend, the strongest of which will be capable of strong wind
gusts, frequent lightning strikes, and locally heavy rainfall.

.SPOTTER INFORMATION STATEMENT...
Spotter activation is not anticipated today and tonight.
