Marine Weather and Tides
Lealman, 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.

341 am edt Mon jun 25 2018

Short term (today and Tuesday)
Aloft - a ridge centered over the deep south sprawls across much of
the gulf region. Surface - atlantic high pressure extends across fl
to the central gulf of mexico... With an axis through central fl
early this morning lifting into northern fl later today and
meandering there during Tue as it weakens. A gentle east to
southeast 1000-700mb flow prevails through tonight with model pwat
values 1.8 to over 2 inches into the evening then dropping down to
1.7-1.9 inches over night. For Tue the 1000-700mb flow becomes light
and more southernly. Pwat values of 1.7-1.9 inches increase late
tue to near 2 inches. The surface pressure gradient stays relaxed
enough to allow the west coast sea breeze to form each
afternoon... Fairly close to the coast for today but reaching
farther inland Tue as the high pressure weakens.

Typical summertime weather for an easterly flow pattern will be in
place. Showers and thunderstorms start very late mornings inland
then shift toward the gulf coast during the afternoons with
increasing coverage due to the sea breeze convergence. The highest
rain chances will be along and west of the i-75 corridor this
afternoon then along and east of i-75 Tue afternoon with the enhanced
sea breeze. Showers and storms wind down in the late afternoon
and early evening as they drift west. A few storms will become
robust with gusty winds... Frequent lightning... And heavy rainfall
making localized flooding possible. Temperatures run near or just
above normal by a couple of degrees.

Mid long term (Tuesday night-Sunday)
Period will begin with an extensive u l ridge across the southern
tier of the u.S extending from the desert southwest... Across the
southern plains... To the florida peninsula. An u l disturbance
will dig over the great lakes on Wednesday with the trough axis
approaching the eastern seaboard Wednesday night and Thursday. May
see a brief dip in heights over extreme north florida Wednesday
night, however this will be very short lived as the trough lifts
out to the northeast on Thursday.

An u l disturbance will push onshore the west coast of the CONUS on
Thursday which will help build the downstream ridge with the center
shifting east to the lower mississippi valley. As the S W digs over
the intermountain west on Friday and begins to lift over the
northern central plains over the weekend, the center of the
downstream ridge and associated excessive heat will continue to
build and shift to the ohio river valley and mid atlantic coast.

Florida will be located on the south side of the u l ridge... And
heights will actually lower a bit as the core of the high lifts
north of the area.

At the surface, a weak ridge axis will extend across south central
florida from high pressure over the western atlantic... And will
persist over the forecast area Wednesday through Friday with onshore
boundary layer flow along the west coast of florida. This will
promote scattered showers thunderstorms to develop along the west
coast sea breeze boundary over the coastal counties during the
morning early afternoon hours... Pushing inland and increasing in
areal coverage during the afternoon hours. Highest pops over
southwest florida in region of best l l convergence and deep layer
moisture. Very warm muggy conditions will also persist with winds
off the very warm gulf of waters... With overnight lows several
degrees above climatic normals.

A bit of uncertainty toward the end of the long range period. As
the u l ridge shifts north of the region over the weekend and
florida sits on south side of the u l high... Very possible a few
weak u l disturbances will slide under the ridge and track from east
to west across the peninsula. This would provide some additional
u l forcing to aid in thunderstorm development. Boundary layer winds
will become light from the east to southeast which will enhance
convergence along the west coast sea breeze boundary, holding it
closer to the west coast of florida. Scattered to numerous afternoon
showers and thunderstorms with locally heavy rain possible under
this scenario.

Aviation
25 06z tafs.VFR with light winds becoming se... With an increase in
cu ci through late morning. Bkn mid and high clouds with vcnty tsra
for the afternoon but with brief gusty winds and MVFR vsby cigs.

Anticipate convection winding down around 00z-02z. Winds shift to
onshore during the afternoon then become variable in the evening.

Marine
High pressure meanders across the waters with a relaxed gradient...

keeping winds light to gentle and allowing afternoon sea breezes
near the coast. Isolated to scattered thunderstorms result in
locally higher winds and seas.

Fire weather
A moist air mass with daily chances of rain will preclude any low
humidity concerns.

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.
