.DISCUSSION...
Key Message 1: Cooler temps into mid-week. Warming and wetter
pattern develops into the weekend with some tropical
connections.

Pleasant autumn weather with a drier surface high pressure over
the Mid-Atlantic will build into the region today, with PWATs
dropping to around 0.50 inches. Persistent northeasterly low
level flow into the mid- week should keep temperatures near to
just below normal with dry weather expected. Weak surface
ridging is expected to continue into the late week along with
some building heights and temps returning to near-above average.

Attention turns to a more active weekend as moisture returns
across the region with southerly to southeasterly flow aloft.
Although guidance has struggled with the timing of 92L,
currently in the Bay of Campeche and showing some loose signs
of organization as of 18z, probs are up to 90% of development
in the next 7 days per the NHC, confidence is increasing in a
tropical connection to this flow. Guidance is in decent
agreement in the overall track with fairly predictable steering
flows across the Gulf into the southern US, bringing the system
somewhere from Louisiana to the panhandle of Florida; timing and
intensity differences within the guidance are high, especially
between AI, hurricane, and global physics based ensembles
however. Regardless, a strong surface ridge with persistent,
deep easterly component will effectively serve as a road block
to how far east the core of the tropical system can make it.
Despite the core of the system likely remaining well to our
west, this surface ridging presents an impressive overrunning
setup with a plume of deep tropical moisture surging northward
along the system`s eastern flank. Model cross sections show the
expected impressive fetch of potential isentropic lift
throughout the area along with nearly saturated and weakly
unstable profiles as the tropical moisture arrives as
effectively a warm front. Exactly where strongest meso-
synoptic scale lift sets up and the extent of the high PWAT`s
are still very difficult to guess at, but chances for impactful
heavy rain are there. But regardless, widespread rain with some
breezy winds as the pressure gradient tightens across the area
looks to be the most likely impact at this time, but obviously
lots to still watch and monitor once the system actually forms.
Finer scale details will determine if this would just be a
beneficial rain or more of a flooding threat.

.AVIATION /18Z TUESDAY THROUGH SUNDAY/...
VFR conditions through the TAF period.

Drier air continues to push into the area, allowing this
morning`s low ceilings to clear. A few high clouds are passing
to our south and east, otherwise mostly sunny skies prevail.
East- northeast winds have increased to around 10 knots, with
occasional gusts of 15-17 knots. Winds should diminish around
sunset, with mostly clear skies expected tonight. Fog and low
stratus are not expected, though a few localized areas may
develop along the rivers. Otherwise, VFR conditions continue
into Wednesday with light northeast winds and only a few
passing cirrus clouds.

EXTENDED AVIATION OUTLOOK...VFR conditions are
expected into the late week with drier air in place.
Restrictions may become possible by the weekend.
