.DISCUSSION...
KEY MESSAGE 1...Above normal temperatures and dry conditions
through Wednesday with increasing rain chances Thursday into
early next week.

High pressure stretching along the Eastern Seaboard will
maintain quiet weather through tonight and most of the day
Wednesday. A light southeast to southerly flow will bring in
additional moisture and some warmth throughout this prolonged
period. As a matter of fact, the increasing moisture and falling
temperatures at night could result in some patchy fog in
interior mountain valleys and along and east of the Blue Ridge
Mountains. Otherwise, mostly sunny skies expected through midday
Wednesday, before some increasing clouds in the afternoon. Lows
tonight will fall back into the upper 40s and low 50s with
highs back in the low to mid 70s Wednesday. A few locations
could punch into the upper 70s in the lee of Alleghenies and
south/east of Washington, D.C. Wednesday afternoon given
increased southerly flow.

The high pressure ridge will break down to allow for increasing
clouds and increasing rain chances from west to east Wednesday
night. Lesser rain chances on Thursday as a trough moves by to
the north. The resultant surface front is set to cross sometime
Thursday morning into Thursday afternoon leading to scattered
showers and a few t-storms. Rainfall amounts Thursday will range
between a tenth to a quarter of an inch, with locally higher
totals west of the Alleghenies where better forcing resides.
Despite increased cloud cover expect highs back into the low to
mid 70s (60s mountains) Thursday afternoon. Storm total rain
through Friday night will generally be between a quarter to a
half an inch.


KEY MESSAGE 2...Rain chances continue into early next week with
cooling temperatures.

Temperatures drop towards the beginning of the weekend as Thursday`s
cold front passes offshore, with afternoon highs back in the 60s on
Saturday. Skies could temporarily clear Saturday afternoon into
Sunday as the earlier upper-level trough continues east. Meanwhile,
a second trough moving southeast from the Canadian Rockies will move
in closely behind, with a stemming cold front moving through
beginning late Sunday into Monday. This second upper level low could
bring additional rain showers to the region, although total QPF
estimates continue to be uncertain. Thunderstorm potential should be
lower with this second wave, and any rainfall will continue to be
beneficial after 2+ weeks in a dry spell.

Temperatures continue to cool towards more seasonable November
normals, with highs in the low 60s over the metros and low 50s
in the mountains by Monday. Overnight lows could return to the
low to mid 30s in some areas early next week as these cold
fronts move through. Zonal flow overhead returns by midweek next
week.

.AVIATION /01Z WEDNESDAY THROUGH SUNDAY/...
VFR conditions and light south/southeasterly winds at less than
15 kts will continue through Wednesday as high pressure
meanders over the western Atlantic. Some patchy fog could occur
again along and east of I-95 tonight/Wednesday morning given
the uptick in moisture advection. This will lead to brief
reductions in cigs/vsbys during the 9-14z/4-9am time window.
VFR conditions continue into Thursday although brief sub-VFR
reductions are possible at times with showers and even a few
thunderstorms Thursday morning into Thursday afternoon. South to
southwesterly winds continue at less than 15 kts.

Temporary restrictions could linger throughout the day Friday
as continued rain showers track through the Mid-Atlantic.
Conditions should improve throughout the day Saturday, with
winds flowing northwesterly in the wake of the front. VFR
conditions for most of the weekend, with additional rain showers
possible beginning late Sunday into Monday as a second cold
front pushes through.

&&

.MARINE...
No marine hazards are expected through Wednesday morning. Winds will
remain light out of the south and southeast through Wednesday as
high pressure pushes offshore. By Wednesday evening into Thursday
morning, expect the potential for southerly channeling due to the
high offshore and incumbent trough from the northern Ohio River
Valley. Confidence in this occurring is low with a focus over the
middle and open waters.

Winds shift northwesterly on Saturday in the wake of a cold
front, potentially crossing SCA thresholds by the afternoon. Winds
temporarily diminish on Sunday evening before increasing to 20
knot gusts ahead of a second cold front on Monday.
