.UPDATE...
Issued at 1020 PM EST Thu Jan 4 2024

Cloud cover has largely dissipated across east central Florida,
allowing temperatures to fall efficiently into the upper 40s to
mid and upper 50s. Recent ACARS soundings near MCO show a very
dry, stable atmosphere with northeasterly low-level flow up to
around 800mb, before winds switch to the west rather uniformly.
High clouds are following the westerly flow, moving east across
the peninsula.

No major changes were applied to the previous forecast in this
update, other than to line up current analysis with temperature,
wind, and sky trends. We are still on the way to morning lows in
the 40s for much of the area, with locations east of Interstate 95
bottoming out in the low to mid 50s. It would not be a surprise
to see some interior portions of Lake and Volusia counties fall
into the low 40s for a brief time Friday morning. Despite this,
light winds should keep wind chills right around or above 40
degrees.

.MARINE...
Issued at 1020 PM EST Thu Jan 4 2024

Tonight...Boating conditions are forecast to gradually improve
closer to daybreak Friday. Currently, Buoy 41009 is reporting
10-14 kt with seas around 5.0 to 5.5 ft. Small craft should
continue to exercise caution into Friday morning in the offshore
Gulf Stream waters. NE Winds around 10-15 kt will continue veering
onshore, decreasing to around 10-13 kt around sunrise.

.AVIATION...
(00Z TAFS)
Issued at 1020 PM EST Thu Jan 4 2024

VFR are ongoing and forecast through the TAF. Light NNE winds veer
onshore through 15z, increasing to around 10-13 kt during the day,
with some gusts around 20 kt possible from MLB/VRB south along the
Treasure Coast. Clouds increase ahead of another cold front after
00z Sat., which looks to bring SHRA and possibly a TS or two on
Sat., well beyond the scope of this TAF period.

.HYDROLOGY...
Issued at 1020 PM EST Thu Jan 4 2024

The St. Johns River at Astor remains in Action Stage. It is
forecast to remain at or near Action Stage into the day on Friday.
