.DISCUSSION...

...Cold again tonight with patchy frost south interior...

Tonight...High pressure ridge axis extending into central Florida
from the GOMEX will sag south across south Florida late tonight.
As a result, the coldest temperatures will be found across our
southern counties closer to the ridge axis. Lows are expected in the
mid 30s over Okeechobee county and mainland portions of Indian River
and Saint Lucie counties as well as adjacent portions of southern
Osceola and SW Brevard. While freezing temperatures are not
expected, patchy frost should occur toward morning inland from the
coast and south of a line from Melbourne to Lake Kissimmee.

Farther north across metro Orlando, Lake and Volusia counties,
increasing westerly flow will limit the temp fall to the low and mid
40s.

Tuesday (modified)...After another chilly start to the day,
temperatures will moderate more quickly than today as westerly
boundary later flow kicks in ahead of an approaching cold front, and
becomes breezy by noon. The front will begin pushing across the
northern CWA by late afternoon, and likely bisect the central
peninsula by early in the evening (00z/7PM). Some increase in high
clouds is expected and there should be some stratocu off the Gulf
however it shouldn`t inhibit temps from warming into the low to
mid 70s.

&&

.AVIATION...VFR. SKC overnight with SCT-BKN250 developing 12Z-15Z.
Winds from 250-270 will average around 16G25KT over most of the
aerodromes in the afternoon.

&&

.MARINE...
Tonight-Tuesday...Winds are backing to W/WSW across the northern
waters as ridge axis slips southward this evening. This offshore
flow will increase Tue reaching 20 knots offshore Volusia/Brevard
counties late in the day. Seas will be suppressed though ranging
from 2 feet just off the coast building to 6 feet well offshore late
Tue.

&&

.FIRE WEATHER...
Tuesday...Westerly low level winds will increase into the afternoon
and become breezy. High temps will warm into the low and mid 70s
producing Min RHs between 35 and 40 percent in the afternoon.
