Current-Tonight...Onshore winds resulting from the earlier seabreeze
will abate over the next couple hours as light and variable winds
are expected to become NWRLY drainage overnight and toward sunrise.

With a dry airmass in place, min temps will range from the U40s/L50s
NW of I-4 to the L-M60s along the St. Lucie/Martin coasts. Some
patchy fog wl be possible across Okeechobee, interior St.
Lucie/Martin counties for early Thu morning. The current forecast is
in good shape.

prev disc...

Thu...A weak trough just offshore initially with light NWRLY winds
over land will push further away or become diffuse allowing these
northerly winds to become NERLY along the coast in the afternoon
with a very slow push inland through sunset. Any lingering shower
threat along the Treasure Coast early in the period should push
seaward during the morning. Weak high pressure resides across the
area. Becoming MSunny across the I-4 corridor with dry conditions
and a few more clouds southeastward toward the Treasure Coast,
especially earlier in the day. Max temps near 80/L80s interior and M-
U70s at the coast.


VFR conds thru Thu. Will monitor for some shallow MIFG/BR potential
late overnight into early Thu morning, generally inland from the
Treasure Coast and into Okeechobee County. Morning NWRLY flow
becoming onshore near the coast in the afternoon spreading further
into the interior Thu evening.


Current-Thursday...Weak high pressure influence continues with
generally light pressure gradient in place. Light winds wl switch to
W/NWRLY after midnight and into early Thu morning for much of the
local waters. Speeds generally under 10 kts through the day Thursday
and perhaps just a little higher (10-13 kts) later in the night and
into Thu away from the coast. Seas mainly 2-3 ft. Some shower
activity could persist, especially over the Gulf Stream into early
Thu. The initial northerly component of wind early Thu will
gradually transition to NE/ENE near the coast and N/NNE over the
offshore waters.


Thu-Extended...Latest model guidance coming in drier, as a rather
dry airmass will produce min RH values from the U20s to M30s across
much of the interior in the afternoon. Surface and transport winds
will remain generally light. Smoke dispersion will be Poor to Fair.
Moisture values begin to moderate again for Fri into the weekend.
Dispersions will be Fair to Generally Good for Friday and perhaps
even higher over the weekend.
