.PREVIOUS DISCUSSION...
Issued at 248 PM EST Fri Jan 24 2025

Rest of Today-Tonight...Clouds continue to clear from the area
from northwest to southeast, as low pressure pulls away from the
region and into the Atlantic. Clearer skies and continued
northerly winds will lead to some of the coldest temperatures of
the season at several locations across east central Florida.
Overnight lows are forecast in the 30s for most of the area, with
lower 40s along the Space and Treasure Coasts. Areas north of I-4
are forecast to reach the lower 30s, with a Freeze Warning in
effect for Lake and inland Volusia Counties. A bit of a tricky
forecast for frost, though, as guidance supports winds in most
locations remaining above the typical 5mph or less needed for
widespread frost. However, patchy frost will remain possible for
nearly all of the interior, especially in wind-sheltered
locations. With winds remaining elevated, wind chill values are
expected to be in the mid-20s to mid-30s for a majority of the
area. Cold Weather Advisories have been issued for all but the
coastal areas of St Lucie and Martin Counties, where a slightly
more northeasterly wind is expected to keep wind chills closer to
the mid to upper 30s. Proximity to the Atlantic will be a limiting
factor for both temperature and wind chill along the coast from
Cape Canaveral southward, especially if winds veer north-
northeasterly.

Saturday-Sunday (modified previous)...After the colder start to
Saturday, highs will still be below normal but not as cold as
Friday, as high pressure building into the Southeast U.S. allows
low level winds to veer onshore and slacken into the weekend. Max
temps will reach the 60s, except upper 50s along the Volusia
County coast. A gradual warming trend will then continue to take
hold through Sunday, with lows Saturday night in the 40s across
much of the area, and upper 30s across normally colder locations
northwest of I-4. However, temperatures and wind chills will
remain above criteria for any cold weather products. Highs on
Sunday will be a little closer to normal, in the upper 60s to low
70s, except low/mid 60s along the Volusia County coast. Lows then
fall to the mid 40s to mid 50s Sunday night. Conditions will
remain dry through the weekend.

Monday-Friday (previous)...High pressure settles southward across
the region into next week, which will allow a gradual warming
trend to continue. Dry conditions also look to generally prevail,
with rain chances remaining out of the forecast. Highs will either
be near to slightly above normal in the 70s, with overnight lows
mainly in the 50s, with some 40s holding on north of I-4 on
Monday and Tuesday nights.

.MARINE...
Issued at 248 PM EST Fri Jan 24 2025

Low pressure moving away from the region and into the Atlantic
will maintain poor to hazardous boating conditions over the local
Atlantic waters into Saturday afternoon. North to north-
northeasterly winds 20-25kts overnight will diminish to 15-20kts
by daybreak and under 15kts into Saturday afternoon. Seas up to
7-10ft, with the highest over the Gulf Stream, will also diminish
to 4-6ft by Saturday afternoon. Small Craft Advisories remain in
effect.

Improved boating conditions then prevail through the period, with
winds remaining under 15kts and seas 2-4ft, as high pressure
lingers over the area.

.AVIATION...
(00Z TAFs)
Issued at 616 PM EST Fri Jan 24 2025

Continued mainly VFR with dry conditions forecast over the next
24 hours. CIGs 035-045 across the Treasure Coast will be improving
as these lower cloud decks push south/east this evening. Gusty
NW/N winds will diminish a bit to 5-10 kts across the interior,
but will remain a bit elevated 8-12 kts along the immediate
Space/Treasure coasts with some higher gusts. Ample sunshine on
Sat, after a cold start, with winds veering NE/ENE up to 10 kts
interior and 10-15 kts at the coast as high pressure builds across
the southeast U.S., north FL and into the western Atlc. A few
higher gusts can be expected on Sat as well.

.FIRE WEATHER...
Issued at 248 PM EST Fri Jan 24 2025
