What's New / NOTES
3/3/2018 - There is a new GOES Satellite for the east coast that required rewriting that part of the code. Please report any issues.
6/25/2017 - NOAA is having a major issue that impact the 7 day forecast load times. Many users are reporting problems. The issue has been reported.
5/23/2017 - Worked with NOAA again to speed up the 7 day forecast load times. Thanks to them for being responsive.

Discussion
Treasure coast strong severe convection dialing down...

current-tonight...

active wx acrs the treasure coast lake-o region ahead of a cold
front extending from sebastian inlet to the NW shore of lake-o.

Strong svr tsras psbl south of a line from vero beach to okeechobee
thru late aftn along a tight moisture boundary marking the leading
edge of the trof. Large hail and strong wind gusts a decreasing
concern (of recent). Most stout storms should push south of
treasure coast 21z.

A well dvlpd cyclone over the ms valley will crank its attending
cold front from the treasure coast lake-o region to the vcnty of
jupiter inlet by arnd sunset, then into the fl straits NRN bahamas
aft midnight. Frontal moisture band will ride in tandem, bringing an
end to the latest bout of unsettled wx. Behind the front, Sat pics
and ruc40 analysis show dry stable air pushing acrs the i-4 corridor
with minimal cloud cover and h100-h70 mean rh values dropping to
arnd 50pct and pwat falling blo 1.00".

Will keep a slgt chc of shra in for the treasure coast lake-o areas
thru midnight as residual moisture and enhanced low lvl convergence
in the vcnty of the front could allow a few shras to linger thru
late evng. Precip ending aft 04z. Slightly cooler overnight as
post frontal dry air advection pushes sfc dewpoints into the
u50s l60s... Min temps on the same order.

Wed-wed night...

post frontal ridge will bring a very dry stable airmass into fl
peninsula with pwat values fcst to drop to arnd 0.75", h100-h70 mean
rh values falling 40-50pct, avg dewpoint depressions increasing to
25-30c thru the h85-h50 lyr, and a 10-15c subsidence inversion
dominating the h95-h70 lyr. Origin of the airmass was the
central SRN plains, so post-frontal cooling will be minimal with
near full Sun and light wrly flow. MAX temps in the l m80s, within
a deg or two of climo avg.

Thu-sat... (partially from previous) despite a fast-moving and
energetic flow pattern aloft over the eastern-third of the nation,
mostly dry conditions are expected from mid to late week. Energy
from the first closed low will become absorbed within another
northern-stream shortwave over the northeast late Wednesday to
early Thursday, giving way to two additional shortwave troughs
that will dig toward the deep south through late week, the first
Thursday night and the second on Saturday. Their accompanying
surface fronts will have limited moisture to work with as they
cross the peninsula, supporting only a small chance of pops on
Friday afternoon into early Saturday. Low-level synoptic flow
remains offshore through the period, though the pressure gradient
looks weak enough for the atlantic sea breeze to shift winds
onshore along the coast each afternoon. Pleasant conditions are
expected as offshore flow keeps dewpoints in check and temps
remain near to a few degrees above their late april average.

Sun-mon... (from previous) surface high pressure will build over
the mid-atlantic as broad ridging replaces the trough aloft,
leading to a notable up-tick in onshore flow early next week.

Afternoon temps should trend closer to normal given the
increasingly breezy east winds while remaining above normal at
night. Moisture looks low enough to keep the extended dry for now.

Marine
Tonight... Marginal to poor boating conds as a moderate to fresh W nw
breeze pushes a frontal boundary thru the LCL atlc waters thru
midnight. Winds diminishing to a gentle to moderate W NW in the
predawn hrs as the front works its way into the fl straits nrn
bahamas. Seas 2-4ft nearshore and 3-5ft offshore... Up to 6ft in the
gulf stream, but with rough short pd chop as the atlc waters become
fetch protected. Chc of shras slgt chc of tsras south of cape
canaveral thru late evng, then a slgt chc of shras south of
sebastian inlet overnight.

Wed-wed night... Gentle to moderate post-frontal W NW breeze thru
midday, diminishing to a light to gentle breeze by mid aftn as a
storm system lifts up the ERN seaboard. Seas 2-3ft nearshore and 4-
5ft offshore, subsiding to 2-4ft areawide overnight.

Thu-sat... (from previous) a series of mainly dry frontal passages
will maintain offshore winds through late week. However, a rather
loose pressure gradient indicated by the models suggest the
atlantic sea breeze circulation will disrupt the offshore flow
from time to time in the afternoon, most notably on Thursday. Seas
2-4 feet nearshore and 3-5 feet offshore early Thursday morning,
generally 2-3 feet thereafter.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
