.SYNOPSIS...
Another day of warm and dry weather. A weak frontal system will
bring a chance for showers and storms tonight and Monday.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
Dry and even warmer today as strong high pressure remains over
the area and warm air advection will be in full tilt as a strong
southerly flow takes over.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH TUESDAY/...
Shower and thunderstorms chances return later tonight as a weak
and slow moving cold front approaches and drags through the area.
Will leave in the chance for thunder, but most of the instability
is elevated, shear is weak, there is not much of an air mass
change behind the boundary, and the time of day will all be a
hindrance toward the development of convection.

Front takes its time to pass through the area Monday. Without a
good push from the upper levels, the boundary will make it to Central
Pennsylvania in the afternoon and then washout, as what limited
support aloft moves toward the Mid-Atlantic. Will decrease pops
from west to east Monday and also cloud cover.

A secondary cold front will slowly swing through late Monday night
and Tuesday. Again, it will be passing through with little
instability or upper level support. The difference with this
second front, will be the push of cooler air behind it.

&&

.LONG TERM /TUESDAY NIGHT THROUGH SATURDAY/...
Upper troughing will slowly become the norm over the region from
mid-week onward. This is likely to trend temperatures back toward
and eventually below normal through the week into next weekend.
However, without any significant push of humid and unstable air,
conditions should be more quiet than they have been recently.

&&

.AVIATION /08Z SUNDAY THROUGH THURSDAY/...
VFR conditions are forecast to persist through the TAF period.
Little in the way of significant fog is expected this morning.
Scattered cumulus will form by midday in the heat of the day.
Southerly wind of around 10 knots are expected this afternoon.

.OUTLOOK /SUNDAY NIGHT THROUGH THURSDAY/...
Shower and thunderstorm restrictions are possible with a Sunday
night/Monday cold front.

&&

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