.SYNOPSIS...
An active weather pattern drives shower and thunderstorm
activity each day through the forecast period.

&&

.NEAR TERM /THROUGH TONIGHT/...
A weak upper-level disturbance currently over the eastern Great
Lakes is supporting shower and thunderstorm activity over
central and eastern Ohio this afternoon, with focus along the
leading edge of a plume of deep-layer moisture characterized by
PWATs around 1.8 inches. This system continues to push eastward
through tonight, bringing those showers and storms into the
local area this evening and along with it the potential for
brief, heavy downpours. Widespread severe weather is not
anticipated with these storms, but we could see gusty winds in
the stronger cells given DCAPE values of 800-1000 J/kg currently
overspreading the area per latest mesoanalysis.

Thunderstorm activity generally wanes after sunset as we lose
daytime heating, though we could see isolated to scattered
showers continue through overnight hours as the mentioned upper
disturbance passes overhead.

&&

.SHORT TERM /FRIDAY THROUGH SATURDAY NIGHT/...
A weak front pushes through the local area from northwest to
southeast early Friday. Showers and storms along/ahead of the
front should depart most of the area by mid or late afternoon,
with the exception being the higher terrain to the east where
development could persist into evening hours with help from post-
frontal upslope flow. The deep moisture plume eventually gets
pushed east of the area and we dry out Friday night, but don't
stay that way for long as the next upper shortwave approaches
from the west by midday Saturday, bringing with it increasing
moisture and higher chances for showers and storms late
Saturday afternoon through Saturday night.

&&

.LONG TERM /SUNDAY THROUGH THURSDAY/...
Broad eastern CONUS trough will remain in place for the bulk of
the period. Several waves progressing through the trough will
lend to at least chance PoPs for precip each day, with dry
conditions best progged for Tuesday at this point. The models
remain inconsistent with the approach and passage of a boundary
late in the period, with some deterministic guidance bringing
the boundary in sooner than others.Throughtout the period,
temperatures will remain near climatological values.

&&

.AVIATION /18Z THURSDAY THROUGH TUESDAY/...
Expect mainly VFR conditions through 00Z. The one exception
will be ZZV where a trough is slowly pushing east and will be an
area where showers and thunderstorms will develop with the days
heating. Thus, have put a TEMPO group at ZZV from 20Z-22Z for
thunder. This activity will quickly die after 00Z with most
sites experiencing IFR and below cigs overnight at all the
terminals. Winds will be light and variable through much of the
period. Improvement tomorrow at the terminals will be slow with
most sites returning to MVFR by 18Z.

.OUTLOOK...
Fog will be possible once again Thursday night, particularly for
regions that do receive rain. Cigs/vis will lift to VFR once
again Friday morning after the passage of the surface trough.

&&

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