update (overnight through Wednesday night)... Well
folks... Some people in florida like to see a few periods of
cold temperatures in winter, and some certainly do not. For
the next couple of days, the ones that like the cold will be
the happy ones.

Conditions are benign around west-central and southwest
florida this evening... And will remain so throughout the
night. Its dry out there, and temperatures will slowly cool
off, but stay seasonable... As a strong cold
front... Scheduled for our area on Wednesday... Remains off to
our northwest through the duration of the overnight.

Overall... The daylight hours of Wednesday will not be all
that bad either... Other than becoming a bit gusty out of the
north for the second half of the day. The strong cold front
that is bringing some wintry precip to portions of ms al ga
this evening will arrive over the northern fl peninsula ne
gulf of mexico Wednesday morning... And sweep quickly
southward through the peninsula during the day. By the time
the front gets down to the florida peninsula... No more
precipitation is expected... As the strong synoptic ascent
shifts eastward... And not southward with the front.

Therefore... This will be a dry frontal passage, with just a
band of clouds likely hiding the Sun for a few hours.

Coolest conditions during the day Wednesday will be up over
the northern nature coast, where the front moves through
the earliest... And where highs in the 50s should be
expected. High temperatures warm to the lower mid 60s around
the i-4 corridor... And upper 60s down toward fort myers.

These high temperatures (especially along the i-4 corridor)
will prob occur around midday... And then hold steady or
begin to slowly fall through the afternoon hours.

We all feel the impact of the cold front Wednesday night.

Low temperatures dropping to freezing or below are expected
down to as far south as the i-4 corridor... With mid upper
30s all the way to fort myers. Freeze and hard freeze
watches are in effect from the i-4 corridor northward for
Wednesday night... And it is likely these will be upgrade to
warnings later tonight or Wednesday. Those that do not see
freezing temperatures Wednesday night will still experience
the cold temperatures and low wind chills. It is likely
based on the current forecast, that all zones will require a
wind chill advisory for Wednesday night early Thursday
morning.

Try and stay warm later Wednesday into Thursday everyone.

We are looking at another very cold night Thursday night
into Friday morning as well. However, if you can hang in
there till the upcoming weekend, all indications are that we
will all experience a pleasant and quite rapid warm-up.

Aviation...

vfr conditions prevail through the evening hours with a
light generally northerly flow. Late tonight... A brief
period of shallow field fog (MVFR ifr) is a possibility for
places like klal kpgd. Any shallow fog lifts early
Wednesday... Followed by the approach of a strong cold front.

No rain is expected with this front... However... A period of
MVFR CIGS is possible... Especially for ktpa kpie ksrq as
the front passes. Gusty northerly winds and prevailingVFR
conditions will the be in the forecast for all terminals
from late Wednesday afternoon through Wednesday night.

Marine...

strong winds and rough seas will expand across the eastern
gulf of mexico during the day Wednesday in the wake of a
cold front. These hazardous boating conditions for small
craft operators will continue through much of Wednesday
night before subsiding late Wednesday night into the
daylight hours Thursday. Following the advisory event... High
pressure centered to the north of the region brings lighter
easterly winds and calmer seas for the end of the week.
