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
A sprawling low pressure system at the surface and aloft is over the
tennessee valley this morning, with a cold front extending southwest
into the western gulf of mexico. Winds currently veering to the
south as the storm system moves east and the high over the mid-
atlantic moves northeast. South florida is in an established warm
sector, with a moist and unstable air mass in place. Showers have
focused overnight in a corridor of better moisture and confluence
embedded in the SE low level flow over the northeast part of the
area, with only isolated activity elsewhere.

For the next few hours, with little organized focusing mechanism
for ascent, expect only isolated showers most areas. With some
surface heating this morning, sea breezes should be able to move
inland from both the atlantic and gulf coasts, and a lake
okeechobee breeze may develop as well. With the moist and
unstable air mass in place, showers and thunderstorms should fire
along all of these boundaries by early afternoon. As convection
deepens, mean wsw winds in the cloud bearing layer should allow
for convection and or outflow boundaries to have a preferred ene
motion toward the east coast urban corridor, particularly
broward palm beach counties. Forecast soundings indicate plenty of
instability, dcape of 1000-1200 j kg, veering winds with height,
and 20-30 kts of bulk shear, so a few strong thunderstorms will be
possible. Frequent lightning, heavy downpours, and gusts up to 50
mph will be the main hazards.

Stabilization in the wake of the convection, nocturnal cooling,
and dissipating boundaries should allow shower coverage to
decrease a bit overnight, but still pops will remain in the
slight chance to chance range. Light south winds and high
dewpoints over areas with recent rainfall should allow some
patchy fog to develop over the interior late tonight.

Tuesday, the front gets closer and winds continue to veer around
to southwest. Expect the gulf sea breeze will move across the
state and collide with the atlantic sea breeze near the east coast
urban corridor, firing off convection during the day focusing
especially on the northeast part of our area. A few strong
thunderstorms and heavy downpours will again be a threat. By late
evening and overnight, the front becomes detached from the
retreating upper low with decreasing convergence along the
boundary, which along with nocturnal cooling and post-convective
stabilization should steadily decrease shower and thunderstorm
chances as the front pushes through the southernmost part of the
area.

Wednesday and beyond: drier and more stable air moves into the
area behind the front. Late in the week into the weekend a couple
of shortwave troughs in the northwest flow behind the mean
eastern us longwave trough may force some reinforcing boundaries
into the area, but still some disagreement in the medium range
models on exact timing of the best shower chances, so forecast
pops for now are a broad-brushed in the slight chance category.

Marine
Mostly slight seas, with light to moderate south to southeast
winds today but dominated by sea breeze circulations this
afternoon. Winds veer around to southwest tomorrow. Scattered to
numerous thunderstorms lake okeechobee and the atlantic waters at
times through Tuesday night, with more isolated activity in the
gulf waters. Locally higher winds and waves are expected around
any thunderstorms. Winds turn to moderate northwest late Tuesday
night into Wednesday behind a front with drying conditions.

Aviation
Hit and miss showers may continue over the atlantic for the next
several hours and push inland and north along the coast periodically
through the morning hours. However, confidence south of kpbi is too
low to include mention of vcsh in the TAF package for this morning
with pops overall well under 50%. Towards late morning, showers may
increase again, with a chance of thunderstorms starting around
23 1500z, mainly for the interior portions of florida and TAF sites
north of kmia on east coast. Some storms may decrease vis to below
3sm with ra+ but given lack of confidence of any one hitting a
particular site am handling it right now with vcts and will amend as
needed during the day. Expect south southeast 5-10 kts winds through
the period along the atlantic, around 10-15 kts late morning and
afternoon, with kapf turning south southwesterly 5-10 kts around 16-
18z but otherwise south southeast 5-10 kts after sunrise this
morning and light and variable overnight.

Beach forecast
A high risk of rip currents will persist today at the palm
beaches, with a moderate risk at the atlantic beaches of broward
and miami-dade county. The risk tomorrow is currently expected to
be moderate at the palm beaches.

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.
