.SYNOPSIS...
Warm and humid conditions with daily thunderstorm chances can be
expected through the remainder of the week.

&&

.NEAR TERM /THROUGH WEDNESDAY/...
Warmth and humidity has returned to the region with showers and
storms generating under weak shortwave pulses in wnw flow aloft.

There remains the potential for isolated storms with downburst wind
gusts as the primary severe threat given modest mid level dry air
entrainment. Rainfall rates may also be a problem with warm cloud
rain process and high precipital water; however, that potential will
be offset by sufficient storm movement.

For the overnight, chance POPs have been retained with additional
shortwave energy expected to support more, albeit weaker convection.

&&

.SHORT TERM /WEDNESDAY NIGHT THROUGH THURSDAY NIGHT/...
The warm, humid pattern will continue through the holiday with
embedded shortwave energy maintaining convection chances.

&&

.LONG TERM /FRIDAY THROUGH TUESDAY/...
A largely unchanged pattern is expected, with zonal flow persisting
into the weekend. Minimal changes in upper flow will maintain a
stagnant, warm, and humid airmass, with temperature at or slightly
above average. Once again, precipitation chances will be determined
by shortwave activity embedded in zonal flow.

Precipitation chances may increase early next week with the
encroachment of a frontal boundary.

&&

.AVIATION /21Z TUESDAY THROUGH SUNDAY/...
Scattered showers and thunderstorms are expected to continue as
warmth and humidity interact with crossing shortwave energy.
Confidence in restrictions at individual terminals is thus low;
however, MVFR to IFR cigs with patchy fog may have a better chance at
DUJ and FKL as moisture pools near a stationary boundary.

.Outlook...
Periodic restrictions are likely with abundant boundary layer moisture
and daily convection chances.

&&

.PBZ WATCHES/WARNINGS/ADVISORIES...
MD...None.
OH...None.
PA...None.
WV...None.
