Update
No changes needed to tonight's forecast this evening as skies
remain clear and nnw winds are beginning to diminishing. Threat
for frost is non-zero for hendry and especially glades counties,
but with temperatures expected to drop just a degree or two below
40 and winds likely to not completely calm, the risk seems low
enough to keep out of grids. The light wind and clear skies should
make gulf coastal areas see likely the coldest night of the season
thus far.

Aviation Nw flow diminishes this eve, becoming nne overnight,
though landbreeze will keep east coast TAF sites nw-nnw through
nighttime hours. Wouldn't be surprised if kfll occasionally veers
nne at times. All sites become NE 6-8kts after 14z, veering more
due east after 18z. Kapf likely to stay skc, but extensive
stratocu deck over atlc may break occasional MVFR CIGS through
cycle as flow brings clouds onshore.

discussion...

short term (tonight through Thursday night)
high pressure is continuing to settle into florida as cold air
advection persist. Temperatures today have held below 70 degrees
and with clear skies and lessening north northwest wind,
radiational cooling will be reasonable tonight. Thus, temperatures
are forecast to fall well below normal and near the cooler of the
season thus far. In fact, the forecast low at naples of 46 degrees
would be the coldest since spring. The high pressure begins to
drift east Wednesday, shifting wind to the east and commencing a
slow warming moistening trend. Thus clouds will increase a bit and
temperatures will rise into the low 70s, still well below average
for december.

With the high pressure into the atlantic Thursday and the
influence of a storm system developing over texas, southeasterly
wind on Thursday will bring in deeper moisture and perhaps a few
showers to the region. Despite the cloud-cover, temperatures will
be warmer than previous few days, reaching seasonably mild upper
70s across most areas.

Long term (Friday through Monday night)
forecast derived pwats increase up to 2.00 inches and rain
chances spread across the CWA Friday, as parent low across the
southern region (centered across arkansas mississippi) will extend
its cold front across the sunshine state. The problem here is
that both GFS and ECMWF differ on the exact timing of fropa. Gfs
continues to trend faster than ECMWF with FROPA Saturday
morning afternoon whereas ECMWF is insisting on a Sunday morning
fropa. This gap in timing leads to low forecast confidence beyond
Friday and could create some variability in the weekend forecast
as the week continues. Because of this, pops have been capped at
50 percent for the time being Friday into Saturday. The strong to
severe storm potential with this next low pressure system is too
far in time to discern right now, especially with variances in
models; however, the forecast evolution should be monitored
through the week in case a threat emerges.

Into early next week (after fropa), high pressure returns and nw
will winds prevail, allowing for a dry and pleasant conditions.

Marine...

small craft advisory remains in effect for both seas and winds
through 10 am Wednesday on atlantic waters, caution should be
exercised elsewhere on florida waters. Northerly wind tonight will
transition to the east on Wednesday, then southeast Thursday.

Speeds will be lower Wednesday but could increase to near advisory
levels on atlantic waters again on Thursday. Increasing moisture
will bring a chance of showers to the waters Thursday and Thursday
night. The next cold front is poised to impact the waters sometime
between late Friday and late Saturday.

Beach forecast... The moderate risk for rip currents on gulf
waters should diminish tonight as wind shifts more northeasterly.

For atlantic waters, the moderate risk should prevail at least
through Thursday, with at least palm beach county beaches now in a
high risk for Wednesday as east winds at 15 mph or so combined
with a nely swell of 2-4 ft will create hazardous conditions. &&

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
