KEY MESSAGE 1... Low humidity and precipitation chances until the
weekend, when chances for showers and thunderstorms return and
linger through early-mid next week.

Aloft, a trough will linger over the region through Thu, then
gradually shift ewd and offshore Thu night/Fri as the parent low
lifts newd across New England and into the Maritimes. A s/w will
ride the ne periphery of the anti-cyclone anchored over the Desert
Southwest, dropping sse from the nrn Plains on Thu to the TN/OH
Valley region by Sat/Sat night and amplifying the trough over the
ern CONUS. While details become less clear over the weekend, the s/w
should shear out a bit and lift newd over the weekend/early next
week. At the surface, between the departing low near New England and
the high moving into/across the OH Valley, relatively cool, dry air
will continue to advect swd along the Appalachians/across the mid-
Atlantic through Thu night. The high should gradually weaken over
the OH Valley/n-cent Appalachians on Fri, while the low lifts newd
over the nrn Atlantic. The next low pressure system will strengthen
as it moves across the cent Plains and mid MS-Valley Fri and Sat,
with its progression thereafter still a bit uncertain. The weather
should be mainly dry through Friday, with chances for showers and
storms returning as the s/w approaches from the west over the
weekend. Without a fropa or significant airmass change, expect
chances for showers and storms to linger into early-mid next week,
though confidence decreases beyond this weekend.

.AVIATION /00Z THURSDAY THROUGH MONDAY/...
As of 720 PM Wednesday...

24-hour TAF period: High pressure centered over IL/IN will extend
into the Mid-Atlantic, bringing mostly clear skies and a high
confidence in VFR conditions through the next 24 hours. Any
lingering gustiness over the Piedmont will subside after dark, with
mainly light N/NW winds (7 kts or less) into the day on Thursday.

Outlook: Lift and increasing moisture, ahead of a slow-moving
mid/upr-level trough that will pivot across the OH and TN Valleys,
will favor above average chances of showers/storms and flight
restrictions later this weekend through early to mid next week.
