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
After intersecting outflows with the upper keys cloud line
produced scattered thunderstorms and a few waterspouts, outflow
boundaries from convection over the mainland and florida bay have
become the focus for new showers and thunderstorms near the middle
keys this evening. Light mostly northeast winds cover the keys
otherwise with temperatures in the mid 80s and dewpoints in the
lower to mid 70s.

The evening sounding revealed a lingering moist layer above 12k
feet leftover from convection firing along the lower keys cloud
line this afternoon, reducing mixed layer CAPE quite a bit albeit
temporarily. However light north northeast winds in the wake of
the convection are expected to turn more easterly above the
surface tonight, ushering in gradually more moisture. The presence
of the various slow-moving boundaries and added moisture will
likely lead to isolated to scattered cellular convection as the
night wears on, and thus chance pops remain in order.

Marine
The weak ridge of high pressure is expected to move slowly
northward. Light northeast to east winds will become variable
bayside and gulfside, and southeast in the open straits overnight.

Light to occasionally gentle winds out of the east to southeast
are expected to peak... For lack of a better term... Sunday night.

Otherwise, light east to southeast winds are through the middle of
the upcoming week.

Aviation
A few thunderstorms are expected in the vicinity of marathon
international airport late this evening, but generallyVFR is
expected through early Sunday. Winds will be light northeasterly,
occasionally variable or calm before morning, then resume out of
the east to southeast by sto become established in the keys
coastal waters unday afternoon. Additional showers and possible
thunderstorms may build in the vicinity of the florida keys
terminals by early 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.
