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
Currently
Winds over the islands and marine platforms along the reef have
been less than 5 knots across the board during the morning hours.

Direction has been variable, generally from north to northeast.

The morning sounding found no winds greater than 5 knots all the
way through 6km. In fact, the mean 0-6 km wind is only 2.5 knots.

The morning launch occurred just after a heavy shower in key
west, so it may be somewhat worked over, but even modifying the
sounding for afternoon temperatures shows less MLCAPE than a
normal wet season day, coming in around 800 j kg with CIN of -45.

There is a stable layer between 2-4km with some drying and
subsidence. Overnight and early this morning showers developed
along the lower keys and in the gulf waters north of the middle
and lower keys. The showers in the lower keys were likely along
old cu-line fossil boundary undisturbed in the light flow. The
showers in the gulf waters probably formed along the mainland land
breeze boundary. The showers over the lower keys have dissipated,
but the gulf showers persist. Precipitable water values were
somewhat higher than expected near 2 inches while model output and
the most recent pass nucaps soundings are more along the lines of
1.75 inches or less.

Short term
Given the morning sounding and a cursory examination of model
guidance, the showers around the area should dissipate as the
mainland and cuba heat up and the lower boundary layer environment
over the keys becomes more diffluent. The forecast question for
today revolves around cumulus line development. If the stable
layer and subsident air found in the sounding remains, then cu-
lines along the islands will struggle to develop. Regardless, a
few showers along the cu-line remain a slight possibility.

Marine
Light and variable winds will dominate through this afternoon and
early evening. An isolated shower or thunderstorm is possible. If
showers and storms do develop, they will be near stationary with a
slight drift to the southwest, so should be circumnavigable.

Aviation
Vfr conditions will prevail at eyw and mth this morning. MVFR
ceilings, based at around 2,000 feet, are conceivable at eyw and mth
this afternoon and tonight. This possibility is not great enough to
place in the terminal forecasts at this time. Variable winds near 5
knots expected from just off the surface to about 3,000 feet.

Climate
On this date in florida keys weather history, in 1933, the low
temperature in key west was 70 degrees. This set the daily record
for minimum temperature measured in key west on june 20th, a record
which still stands 85 years later. Temperature records at key west
date back to 1872.
