Aviation
Vfr continues at all terminals with light and variable flow through
14-15z, then southeasterly winds increase to around 10 kt through
the rest of the afternoon. No high confidence in having TS at the
terminals today as sea breezes return early this afternoon and
may push most of the convection inland. Will handle with only
vcts after 17-18z for now. Apf may again experience
westerly onshore flow in the afternoon with sea breezes.VFR
should then prevail after 24 00z at all terminals.

Prev discussion issued 825 pm edt Sat jul 22 2017
aviation...

isolated showers will continue over the coastal waters tonight,
but be suppressed, due to the presence of saharan dust layer
aloft. Light southeast winds will prevail along the east coast,
8-10 kt aft 23 1600z, and a gulf breeze along the west coast. Vcsh
conds may develop during the late morning into the afternoon, but
mainly further inland than the terminals.

update...

aside from a few showers along the gulf coast in the everglades,
activity has pretty much waned for the evening. Have adjusted pops
downward through about 6z, otherwise no changes to the forecast. A
relatively quiet, warm night is expected, weather wise.

Prev discussion... Issued 358 pm edt Sat jul 22 2017
discussion...

short term (tonight through Monday night)
saharan air intrusion already beginning to influence south
florida weather this afternoon, as convective convergence along
atlantic sea breeze has been suppressed and sky has been been
somewhat hazy in appearance. Thunderstorms have been focused
across western portions of the region, and even this have
diminished over the past few hours. Through the rest of the
weekend and start of next week, deep layer ridge will build
westward into south florida, which combined with sal will keep
pops below normal summer levels. Temperatures will be warm,
reaching above 90 each afternoon with minima in the 70s, expect
some low 80s along the coast and east coast urban areas. Scattered
mainly diurnal thunderstorms will mainly be over the interior.

Long term (Tuesday through Saturday)
easterly flow becomes more established for the middle of the week
as high pressure only slowly weakens. Overall rain chances will
increase to more normal for this time of year, but remain focused
over the interior. Temperatures will remain just above
climatological normals, and it's worth noting monthly temperature
levels are on pace to threaten warmest july on record for portions
of south florida, continuing trends of recent months.

At the end of the week, east coast trough may develop, if the
subtropical and upper level hipres can weaken enough. At the
moment, no sensible changes in the forecast during this period,
but pattern could evolve where convective coverage favors east
coast, if swly deep-layer flow can establish.

Marine...

se wind 15 kt or less with seas AOB 3 ft continue next week.

Isolated scattered thunderstorms could induce locally
stronger erratic winds and higher seas.

Aviation...

prevailing -shra with vcts lingering at kapf for next
few hours, potentially ending after a highly uncertain 22z. Atlc
seabreeze has reached all east coast sites with SE winds 8-12kts,
and currently TS development looks to be inland of all but kopf
and kpbi. Late day boundary collisions may bring activity in vcty
of other sites later, but for now have kept vcts out for all but
kpbi where seabreeze won't make it as far inland. Convection
diminishes after 01z, winds becoming light vrb overnight with
potential for isold shra affecting east coast. Threat too low to
mention for the moment.

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.
