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.

Discussion
An active afternoon and early evening across the lower keys is
finally winding down. The cloud line along the island chain
erupted this afternoon, contributing to a cascade of successful
boundary collisions. Locations from the eastern middle keys
to key west have experienced several rounds of thundery showers
since 300 pm. Deep moisture, moderate instability, and
minimal inhibition sampled by this morning's kkey RAOB hinted at
this afternoon's action. Temperatures range from 80 to 85 degrees,
with dewpoints in the lower 70s. Northeast to east winds average 5
to 10 knots, except along the reef adjacent to the upper keys,
where east-southeast winds are 10 to 15 knots.

An upper level low is centered near eastern cuba, meanwhile a
ridge axis stretches west across north-central florida. Between
these two features, an inverted trough has developed within the
lower troposphere. This evening's sounding remains unstable and
moist, although a little post-rain stabilization is prominent,
low in the profile. Low level moisture convergence within the
freshening east-southeast breezes should recharge the stabilized
lower layers overnight. As such, expect shower and thunderstorm
coverage to increase after midnight. Forecast soundings indicate
drier air and some inhibition will push into the keys around
sunrise.

Marine
Atlantic high pressure will begin to build into the area tonight
and Monday with the ridge axis moving north of the keys Monday
night. This will result in light to gentle easterly to
southeasterly breezes. High pressure will begin to retreat from
the area on Tuesday resulting in a weak pressure pattern and light
breezes through Friday.

Aviation
Vfr conditions will prevail at both eyw and mth, but some
additional showers and thunderstorms may bring brief MVFR
conditions to terminals. Initially, vcsh with tempo for shra on
station for both terminals. Another round of vcsh and subsequent
vcts can be expected tomorrow afternoon and evening. Expect winds
to be east tonight, becoming southeast Monday morning and light
south wind less than 10 knots Monday afternoon.

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.
