Aviation
Prevailing dryVFR conditions expected for the eastern terminals
into this evening, with only isolated showers anticipated.

Vicinity showers storms possible at naples between about 20-23z
this evening. Increasing moisture will lead to shower chances
increasing tomorrow morning into at least early afternoon.

Easterly wind regime continues through the TAF period.

Prev discussion issued 822 am edt Wed aug 21 2019
update...

a quiet start to the morning so far, with only isolated showers
over the atlantic and outer gulf waters. No meaningful changes to
the forecast philosophy from the previous discussion below. Expect
showers and thunderstorms to develop around the east coast by late
morning early afternoon before pushing inland and towards the gulf
coast during the afternoon and evening. Made some minor changes to
precipitation coverage and timing through this afternoon based on
radar satellite trends and the consensus forecast from the latest
convection allowing mesoscale model runs.

discussion...

today and tonight: early this morning showers and thunderstorms have
remained mostly over the florida straits and the gulf waters.

Atlantic high pressure will allow east southeasterly flow across the
region. Plenty of moisture remains behind the departing trough
with the 00z mfl sounding having a pwat of 1.89 inches. Satellite
derived precipitable water values show an area of 1.8-1.9 across
the region. As activity begins to increase over the atlantic
waters this morning, some of these isolated to scattered showers
and storms will move over the east coast metro. Best rain chances
for the east coast will be this morning through late morning,
maybe lingering into early afternoon. Latest hi-res models keep
the east coast mostly dry from mid- afternoon through the
evening. Scattered showers and thunderstorms will shift over the
interior and gulf coast this afternoon and evening. Temperatures
today will be in the upper 80s to right around 90 degrees along
the east coast with easterly flow, to low 90s across the interior
and gulf.

After sunset, convection will begin to move offshore and focus over
the waters. Overnight lows will be in the mid to upper 70s to near
80 along the coast.

Thursday: a little bit of drier air tries works into the region on
Thursday. A diurnally driven typical summertime afternoon with sea
breeze driven convection bringing isolated to scattered showers
and thunderstorms across the region.

Friday into the weekend: Friday into the weekend there will be another
moisture surge into the region. As a tropical wave works across
the carribean the northern portion will break off into a surface
trough and approach south florida. This will lead to an increase
in rain chances beginning Friday through the weekend. While it
does not look like a complete washout, as convection will still be
diurnally driven, showers and thunderstorms chances will increase.

Rain chances will remain elevated through the weekend.

Early next week: the moisture will linger across the area as a
high pressure develops in the gulf with winds becoming more
southerly continuing the moisture increase as we end the weekend
and move into next week. Sea breezes will be the focus of
convection but with southerly flow, highest chances will be over
the interior, lake okeechobee and palm beach region.

Marine...

east southeasterly winds will prevail throughout the rest of
the week. Seas will be generally 2-3 feet in the atlantic, and 2
feet or less in the gulf. Showers and thunderstorms will be possible
each day and night over the local south florida waters. Increased
moisture Friday into the weekend will bring elevated precipitation
chances. Gusty and erratic winds with locally higher seas are
possible in and around any convection.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. 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.
