Apollo Beach, FL

Version 3.4
What's New / NOTES
5/20/2018 -- NOAA is having problems with the data feed that I use to draw the graphs. They are aware of the issue and working to resolve it. Sometimes changing the location by about a mile will give a correct graph. 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.

Short term (tonight - Tuesday)
Little overall change through Tuesday as the eastern gulf of mexico
and florida continue to reside under weak mid upper level ridging
with the surface ridge axis across north central florida. The
east to northeast low level flow will continue and therefore with
daytime heating and the sea breezes we should see convection
develop and move westward with the highest pops along the coastal
counties during the late afternoon and early evening. The deepest
moisture, precipitable water between 1.8 and 2 inches will remain
across our northern and southern zones with lower values, less
than 1.6 inches, across central florida. Therefore, the best
chances of seeing convection will be across the northern nature
coast and southwest florida. Convection will move offshore during
each evening with partly cloudy skies during the overnight hours.

Temperatures will remain near to above normal with overnight lows
in the 70s and daytime highs on Wednesday in the upper 80s to mid
90s.

Mid term long term (Tuesday night - Monday)
Aloft - ridging initially centered over the southeast corner of the
nation slowly shifts out over the atlantic and flattens some as a
low trough tracks from the central plains to southeast canada by
sun. The ridging shifts back west across fl and the eastern gulf of
mexico mon. Surface - atlantic high pressure broadly ridges across
fl and over much of the gulf of mexico. It S axis resides through
north-central fl at mid-week but slowly slides down the state... In
response to a boundary trough moving across the gulf coastal
states... And reaches south fl thu. The axis remains there through
the weekend then begins to lift north for the start of next week.

A warm and moist air mass will support showers and thunderstorms
with generally scattered coverage. Light flow Wed will favor the
interior with the most coverage. Then as the ridge axis moves south
westerly flow takes over for Thu with late morning early afternoon
showers and storms over coastal counties that shift inland and
eastward during the afternoon and early evening hours. This westerly
flow will provide an increase in moisture with some enhanced shower
and storm coverage for the weekend. Mon will be a transition day as
westerly flow gives way to easterly with more uniform shower storm
coverage over the area. Temperatures run on the warm side of normal.

Aviation
Isolated to scattered showers and thunderstorms could cause some
MVFR local ifr conditions this afternoon and early evening, then
convection will move west out into the gulf during the late
evening with mainlyVFR conditions prevailing overnight. Some more
MVFR ceilings will be possible Wednesday morning once daytime
heating gets underway. Brief gusty winds up to around 30 knots
will be possible in convection, otherwise easterly winds at 10
knots or less will shift to onshore at tpa, pie, and srq as the
sea breeze moves inland this afternoon and again Wednesday
afternoon.

Marine
Surface high pressure will extend southwest across the north central
florida peninsula today then sink south to across the southern
peninsula by the end of the week. Tranquil boating conditions with
light northeast to east winds with slight seas and an onshore sea
breeze component developing along the coast in the afternoon can be
expected across the waters through Wednesday with scattered
thunderstorms during the late afternoon and evening hours through
Wednesday. During Thursday and Friday a southwest to west wind flow
will develop over the waters with scattered showers and storms
expected along the coast during the late night and morning hours,
then moving to inland locations during the afternoon and evening.

Wind and seas will be higher in the vicinity of thunderstorms,
otherwise no headlines are expected.

Fire weather
No fire weather hazards are expected for the next several days as
relative humidity values will remain well above critical levels.

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.
