.DISCUSSION...
KEY MESSAGE 1...Quiescent weather expected through the end of
the week.

High pressure moves offshore today turning the winds out of the
south. This will yield a milder day with temps climbing back
into the 70s. Temps warm up to near 80 Thu before the passage
of another dry cold front. Temps cool off slightly for the end
of the week as weak high pressure of Canadian origin builds in.

KEY MESSAGE 2...Increased rain potential late this weekend into
early next week.

The main feature to watch in the extended portion of the forecast
will be what becomes of Tropical Depression 9. Key steering features
will be a ridge in the western Atlantic, a trough/closed low over
Texas, and eventually a trough ejecting from the northern Rockies.
The NHC forecast has the remnants of this system moving into the
Tennessee and Ohio Valleys over the weekend, although there still
remains considerable uncertainty on the track and especially forward
speed of the system. Even despite this westward position of the
cyclone, moisture from both the Gulf of America and Atlantic
will likely be transported northward into the Mid Atlantic. Rain
will become increasingly likely Sun, although as mentioned,
this timing could vary a bit. The remnant low could then move
eastward, potentially extending rain chances into Monday. At
this juncture, the rain will be the main impact from this
system, but we will continue to monitor any changing trends.

It will be important to stay tuned to the forecast over the next few
days, and monitor hurricanes.gov for updated details on Tropical
Depression 9.

Daytime temperatures will likely be seasonal through the weekend and
early next week but will take a dip when rain is the most
widespread. Meanwhile overnight lows will be mild thanks to
increasing clouds and dew points.

.AVIATION /06Z WEDNESDAY THROUGH SUNDAY/...
VFR conditions are expected through the end of the week. Winds
turn S`ly today as high pressure shifts offshore. A dry cold
front Thu will cause another wind shift to the west and
NW into Fri.

VFR conditions with light south to southeast winds are expected
Saturday. Rain and low ceilings are possible late Saturday night
into Sunday as tropical moisture is drawn northward into the
area from the Gulf of America.

&&

.MARINE...
Winds are expected to strengthen today out of the south and
could flirt with marginal SCA conditions this evening. Currently
favoring an MWS given the short duration and marginal nature. A
dry frontal passage Thu could bring another period of marginal
SCA conditions Thu afternoon into Thu night.

Winds will become southeasterly Sat into Sat night, likely
remaining below SCA levels. Winds could increase on Sun,
depending on the evolution of the weather pattern ahead of a
remnant tropical system (current Tropical Depression 9) which
will likely be moving into the Tennessee or Ohio Valleys.
