...New AVIATION...

.KEY MESSAGES...
Issued at 244 PM EST Wed Mar 5 2025

- Fire sensitive conditions are expected Thursday and Friday with
  fire sensitive to critical conditions forecast. A Fire Weather
  Watch has been issued for ALL of east central Florida on
  Thursday.

- Hazardous to Dangerous boating conditions into Thursday across
  the local waters as a result of strong winds and increasing
  seas.

.UPDATE...
Issued at 1003 PM EST Wed Mar 5 2025

Today's cold front and associated rain have departed south and
offshore. Breezy to windy conditions will continue behind the
front through parts of the overnight much of Thursday. Some
fluctuations in the pressure gradient will cause wind speeds to
undulate roughly every 6 hours through the night, decreasing as
low as 10 mph between 7pm-12am and 5am-9am, and picking back up to
as high as 20 mph with gusts to 30 mph between 12am-5am, and after
9am, all while veering slightly from the WSW to the WNW. On the
cool side Thursday with morning lows in the M40-M50s, which
combined with the morning breeze will result in wind chill values
in the L-M40s along and north of the I-4 corridor, which the
exception of the Orlando Metro urban area closer to 50. Rural
parts of Brevard, Orange, and Osceola counties could also see wind
chills down to the M40s. Everywhere else, L-M50s. Dry conditions,
which in addition to the winds Friday, will produce critical fire
weather conditions, and a Fire Weather Watch has been issued for
all of East Central Florida from 11am-6pm.

&&

.PREVIOUS DISCUSSION...
Issued at 244 PM EST Wed Mar 5 2025

Current-Tonight...Shower activity with embedded lightning storms
traversing the central FL peninsula this afternoon. This activity
will continue to spread southward during the afternoon - ending
early this evening across Okeechobee County and the Treasure Coast
on a weakening trend. Primary impacts remain occasional to frequent
cloud-to-ground lightning strikes, gusty to damaging winds (up to 60
mph), small hail, and brief downpours. An ISOLD brief tornado threat
will also be in play. There will be relief to the warm/humid
conditions once the precip moves through. As activity diminishes and
clears the Treasure Coast this evening, the cold front will push
down the peninsula with cooler and much drier conditions.

A Wind Advisory remains in effect until 5 PM from Brevard and
Osceola counties northward for windy/gusty conditions. Expect SW
winds 20-25 mph with frequent higher gusts, up to around 40 mph at
times across much of the area. It will also remain breezy/gusty
across Okeechobee and the Treasure Coast. Winds will veer further
W and slowly diminish for just a bit after the precip pushes
through. However, the pressure gradient remains rather tight and
expect W/NW winds this evening and overnight still in upwards of
15-20 mph sustained with frequent higher gusts continuing.

After a warm day in the U70s to M80s cooler temps tonight with mins
in the L-M50s, except M-U40s across portions of north Lake and north
Volusia counties, and any other normally cooler locations across the
interior.

Thu-Sat...Breezy/gusty W/NW flow Thu will continue to advect a dry
airmass across the area. Temperatures fall below normal on Thu with
highs ranging the M60s to L70s. The coldest morning will occur Fri
with much of the area falling into the 40s. Winds become light and
variable through the day Fri as high pressure builds from the west
and the pressure gradient finally relaxes. After a brief cool-
down, temperatures quickly recover into this weekend with maxes in
the L-U70s Fri and U70s-M80s on Sat. Sensitive fire weather
concerns will be the dominant hazard through the the period,
especially on Thu when gusty winds combine with critical RH
values. No mentionable precip Thu/Fri with a slight chance of
showers returning across the far north late Sat night.

Sun-Wed...Modified...Uncertainty exists in the extended forecast.
The next cold front looks to approach the area late Sun or early
next week, but there are model disagreements in timing and
evolution. A deterministic GFS solution pushes a weak area of low
pressure across the lower southeast, dragging a cold front across
the Florida peninsula late Sun. The deterministic ECMWF pushes a
much broader area of low pressure across the northeast Gulf and
across the Florida peninsula Sun, followed by a cold front passage
into Mon. The current forecast calls for increasing rain chances
areawide on Sun with the greatest coverage (50-60%) focused from
Orlando / Cape Canaveral northward. Precip coverage (20-40%)
lingers into Mon/Mon night. However, conditions could trend drier
much quicker if a GFS solution is realized. A large temperature
gradient in place on Sun (clouds/precip) will promote highs in the
U70s across the north and M-U80s across the south. A cool-down is
then forecast into Mon and Tue with highs in the 70s and lows
mostly in the 50s.

&&

.MARINE...
Issued at 244 PM EST Wed Mar 5 2025

Tonight-Thursday...Gale or near-Gale conditions across the central
Florida Atlantic waters behind a strong cold front, pushing south
through the Treasure Coast waters. W-WNW winds 25-30 kts with
gusts 35-40 kts overspread the waters through the night. Gale
Warnings for frequents gusts over 34 kts are in effect for the
Volusia waters and the offshore Brevard waters. Small Craft
Advisories for winds up to 30 kts with occasional gusts to 34 kts
are in effect for the Treasure Coast and nearshore Brevard waters.
Gale conditions are expected to end by around 10am, but Advisory
conditions will continue into the day Friday, and extensions of
the SCA will likely be needed. Offshore winds temper seas near the
coast, ranging 3-7 ft 0-20 nm miles from shore, but building up as
high as 12 ft in the Gulf Stream by early Friday morning. Dry
conditions.

Fri-Sun...Variable winds less than 10 kts on Fri. Offshore winds
then increase to 10-15 kts on Sat, further increasing to 15-20 kts
offshore Sun. Seas 4-6 ft over the Gulf Stream Fri subside to become
2-3 ft area wide by Sat into Sun. Dry Fri and Sat with precip
chances returning Sun with the approach of the next low pressure
system.

.AVIATION...
(06Z TAFs)
Issued at 1250 AM EST Thu Mar 6 2025

VFR conds forecast through the TAF period though ocnl CIGs btwn
035-050 AGL will affect terminals through 12Z. The primary concern
will be strong and gusty W/NW winds at 15-25kts which will
produce a noticeable crosswind at MCO, likely affecting AAR
somewhat. Pressure gradient weakens markedly by 00Z as high
pressure builds east from the Gulf so gusts will cease and
sustained WNW winds will decrease below 10 knots by 03Z.

&&

.FIRE WEATHER...
Issued at 244 PM EST Wed Mar 5 2025

Thu-Fri...A post-frontal dry airmass will promote sensitive fire
weather concerns. West-northwest winds between 15-20 mph with
frequent higher gusts combined with critical RH values ranging the
M20s to L30s will produce near Red Flag conditions on Thu. A Fire
Weather Watch has been issued for this from 11am-7pm Thu.
Critical RHs in the M20s to M30s will continue to promote fire
sensitivities on Fri, especially west of I-95. Winds become light
and variable Fri.
