Northerly winds behind the cold front passage will be breezy
around 10-12 knots with some occasional higher gust. Later this
evening winds are forecast to shift to the nne and weaken some.

Models are showing some drainage flow early tomorrow morning
shifting winds back to nnw.VFR conditions will prevail throughout
the period.

discussion...

latest water vapor imagery loop displays the cyclonic spin of a
low pressure system centered over north carolina. Wpc analysis
indicates a cold front draping south and southwestward from this
feature, extending across the southern tip of the florida
peninsula. Currently, all surface reporting sites in the CWA are
indicating northwest winds, a sure sign that the front has passed.

Very cold and dry air behind this front will continue to advect
in from the north through early this morning. Satellite derived
pwat indicates values less than 0.50" dropping into central
florida. Mostly clear skies, dry conditions, and a cold airmass
will help to lower minimum temperatures near lake okeechobee to
the lower 30s. A freeze warning through early this morning still
appears warranted for glades and hendry counties. Brisk northwest
winds, sustained 5 to 10 mph, will drop down wind chills to the
mid 20s to mid 30s for a majority of the northern interior and
gulf coast regions. Cold air advection will continue into this
afternoon. Maximum temperatures may struggle to reach the upper
50s by the lake okeechobee region and lower 60s elsewhere. These
values are between 13 and 15 degrees below seasonal norms for
this time of year. Though still chilly tonight, the airmass will
begin to modify, with minimum temperatures forecast a few degrees
above this mornings lows. Thus, not expecting any frost or freeze
conditions to develop anywhere in the cwa.

By Friday, surface high pressure building over the southeast
conus will help veer winds across south florida to the
northeasterly direction. As is often the case, this flow pattern
should modify the airmass by bringing in deeper lower level
moisture from over the atlantic. On Saturday, a weak transient
ridge should help maximum and minimum temperatures rise to near
seasonal averages. Precipitation chances begin to creep higher as
well, with deeper moisture increasing from the south. Both the
gfs and ECMWF agree in drifting a weak low pressure disturbance
eastwards across the gulf Saturday night into Sunday, maintaining
the chance for showers.
