Tricky wind forecast tonight for the east coast tafs sites as
sites fll, pbi, and fxe have too strong of a NE wind to shift to
nw, while the others have made the shift. Have kept the northern 3
as NE through the period, and shift the southern 3 back to the ne
in the morning. There is also some isolated shra in the region,
which have been becoming vcsh to fxe and fll, so have a mention in
the tafs tonight, but no restrictions. Otherwise, predominantly
vfr through the TAF periods for all sites.

Prev discussion issued 711 pm est Mon jan 15 2018
update... Light showers moving along east coast this evening as
surface winds varying between nnw and nne. Latest short range
models suggest activity may linger a little later into the night,
so have updated forecast to support this. Overnight lows will be
5-10f warmer than last night, with temps along the immediate east
coast the most variable depending on if when winds decouple and
back nnw. Current forecast continues lows ranging from the upper
40s and low 50s over the interior and gulf coast to low 60s along
the east coast.

Prev discussion... Issued 408 pm est Mon jan 15 2018
discussion...

tonight and Tuesday: high pressure building south and east is
gradually veering flow to the north-northeast this afternoon. The
wind shift has set up a convergent band just to our north this
afternoon, with additional showers along the boundary where the
nnw offshore flow over land is interacting with the northeasterly
flow over the atlantic waters.

Expect light showers to affect the east coast this afternoon as the
ne winds shift works its way south. With low level flow quickly
veering east-northeast late tonight into Tuesday, don't expect the
driest air to work into south florida. However, should see enough
for land areas to trend dry into Tuesday. Overnight lows will be
warmer ranging from the upper 40s and low 50s over the interior
and gulf coast to low 60s along the east coast.

Wednesday through Friday: synoptic pattern remains progressive
through the latter half of the week. Another strong area of high
pressure is expected to build across the central and southeastern us
behind a departing upper level trough and associated surface front.

Initial narrow moisture band with the front as it moves into the
state is expected to wash out as it moves south, being quickly
overtaken by the significant dry air push behind it. This means as
the front pushes through south florida Wednesday afternoon evening,
minimal impacts are expected other than a minor increase in cloud
cover and showers over the water.

Another period of cool and dry weather arrives behind the front for
Thursday and Friday. Given the timing of the front, lows Wednesday
night are expected to drop into the upper 30s and low 40s over most
of the interior and gulf coast, and upper 40s to around 50 across
the east coast metro. Highs on Thursday will be in the mid-upper
60s.

Surface high continues sliding east Thursday and Friday, quickly
veering winds around to the east-northeast and keeping this period
of cool air relatively brief. Overnight lows Thursday will be around
5 degrees warmer than Wednesday night, and a relatively seasonable
mid 50s to low 60s Friday night.

Next weekend: high pressure slides eastward through the weekend,
with increasing easterly flow advecting in deeper moisture off the
atlantic. Both the GFS and ECMWF show some type of midlevel
disturbance sliding across on Sunday, though they differ in the
details. Whatever the exact solution however, both suggest a return
of atlantic showers moving across the region in the easterly flow.

Highs this weekend will be back into the 70s, and lows back into the
mid 50s except 60s over the east coast metro areas.

Marine... Winds over both the gulf and atlantic waters expected to
veer northeasterly into this evening, with speeds continuing 20-25
knots over the atlantic and 15-20kts over the gulf. Should see a
gradual decrease in winds on Tuesday, with 15-20kts over the region.

Another frontal boundary is expected to move through Wednesday
afternoon, with a few showers possible over the waters. Expect a
return to SCA conditions behind the front with winds becoming N 20-
25kts Wednesday night, becoming NE into Thursday.

Seas are expected to peak around 9-11ft in the gulf stream this
evening, subsiding to 6ft Tuesday night. Seas over the gulf peak at
4-5ft offshore tonight, subsiding to 2-4ft. Expect a return to
higher seas behind the next front Wednesday night. A small craft
advisory remains in effect for the atlantic, lake okeechobee, and
biscayne bay through late tonight.

Beach forecast... Winds have remained a little more north-
northwest so far today, which has limited the rip current threat
so far. However, as gusty winds gradually veer northeasterly this
evening into Tuesday, expect the rip current risk to increase
along the atlantic beach. Will continue the high risk of rip
currents based on the current forecast. &&

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
