.SYNOPSIS...
Humidity increases late this week and into the weekend with
typical afternoon storm chances as temperatures return to near-
normal. Warmer next week and slightly drier. Rain chances
increase during the middle of next week.

&&

.NEAR TERM /THROUGH THURSDAY/...
Scattered thunderstorms have popped up nicely along the
seabreeze boundary this afternoon. Gusty winds within these
storms have occurred, including a couple of gusts over 50 mph at
KILM. After initial ignition from the seabreeze, these storms
are now mostly based on local outflows, following typical
summertime pulse convection patterns. Latest storm motion
analysis in the 0-6km layer shows pretty slow movement at 4kts,
so there be some monitoring needed for ponding on the roads,
especially in low-lying areas. Convection should start to die
off as sunset arrives. Southerly winds will start to calm
overnight. With the ground now wet in some spots, could have
some patchy fog develop late tonight, particularly inland. Lows
in the mid-to-upper 70s.

Thursday morning, patchy fog should mix out soon after sunrise.
From there, it looks to be a pretty similar day. Southerly flow
continues from the Bermuda high, bringing another surge of
precipitable water values near two inches. Seabreeze convection
should start to initiate in the 16-18Z timeframe, with some
gusty winds possible. Highs a bit cooler this time, generally in
the low-to-mid 90s.

&&

.SHORT TERM /THURSDAY NIGHT THROUGH FRIDAY NIGHT/...
Bermuda ridge builds into the region late Thursday and Friday
which should limit widespread convection. A few isolated storms
are possible on Friday with the sea breeze developing and moving
inland throughout the day. As with these patterns, if morning
convection develops, it may trigger convection inland during the
late morning and afternoon as the outflows provide additional
lift. Overall, the ridge and drier air aloft should keep chances
low. There is still some uncertainty in this forecast at the
moment as models trend toward a stronger and closer mid-level
ridge over the western Atlantic through Friday evening.
Overnight lows in the upper 70s.

&&

.LONG TERM /SATURDAY THROUGH WEDNESDAY/...
Rain chances have decreased slightly over the weekend as the
ridge tries to linger near the area into Saturday and Sunday.
With the recent changes, PoPs are only beginning to trend
downward but still show 30-40% chance at this time. Expect a
slow warming trend through early next week with a return to
isolated storm chances. By the middle of next week a frontal
boundary and trough will approach the region from the midwest as
the mid-level ridge retreats eastward. This will bring elevated
rain chances middle of next week into late next week.

&&

.AVIATION /20Z WEDNESDAY THROUGH MONDAY/...
Everybody opens with VFR to start the 18Z TAF period. Scattered
cumulus deck has popped up in the 4000-6000ft range. In
addition, isolated to widely scattered storms have popped up
within the last hour, but none of them are affecting the TAF
sites. Threw in TEMPO groups at KILM, KFLO, and KLBT for TSRA
from 18-21Z this afternoon for good measure.

Convection should settle by sunset. Winds calm inland tonight,
and this may help create some MVFR fog before sunrise Thursday
morning, particularly near KFLO. Southerly flow increases
towards the end of the period, with cumulus and the seabreeze
expected again.

Extended Outlook...Periodic MVFR/IFR expected with isolated to
scattered showers and thunderstorms each afternoon and evening
through the upcoming week. Better chance for convection and
periodic flight restrictions this weekend. Possible patchy
MVFR/IFR low stratus and/or ground fog mainly inland terminals
around sunrise each morning late week.

&&

.MARINE...
Through Thursday... SSW winds this evening become more
southerly by Thursday, with sustained speeds clocking in around
10-15kts. Gradient has relaxed, so not expecting gusts like in
recent days. Main swell out of the southeast decreases slightly
from 1-3ft to 1- 2ft, with long periods at 8-9 seconds.
Secondary swell out of the south hanging steady at 2ft and 4-5
seconds.

Thursday Night through Monday... Bermuda high will build into
the area over the next several days as the gradient will
weakens. Winds become around 10 knots with gusts to 15-20 knots.
Wind waves generally between 2 and 3 feet through Thursday,
becoming around 2 feet later this week and into the weekend.
Southeast Bermuda swell around 2 feet at 9 seconds.
