A backdoor cold front will meander over the region through
tonight before lifting northward as a warm front on Saturday. Low
pressure will track from the Mississippi Valley toward the
Great Lakes Friday night into Saturday. The cold front attached
to this system will push through later Saturday into Saturday night.
High pressure will build overhead on Sunday, before the next
disturbance approaches the area early next week.

Showers are overspreading the region generally from NW to SE as
a backdoor cold front drops into the region. Cooler
temperatures are starting to creep into northwestern zones and
will gradually move southeast this morning. Still seeing some
60s to near 70 the further south and east you go. Rain coverage
will be on the increase throughout the morning as the front
becomes further entrenched into the area. This will also
continue to bring temperatures down throughout the day,
resulting in a much less pleasant day than we have seen

Rain chances continue into tonight as the frontal boundary
remains stalled somewhere over the region. Showers become a bit
more sporadic at times tonight. Low temperatures will only dip
into the 40s though.

An embedded shortwave within a broad upper trough is expected
to move into the Midwest and the Great Lakes on Saturday. A
strong area of low pressure will slide by to our northwest
during this time. Meanwhile, the stalled frontal boundary that
had plagued the region for a couple of days will finally advance
northward as a strong warm front. The primary cold front
associated with the aforementioned low will bring more rain
showers, and possibly a few thunderstorms. Thunderstorm chances
will be dependent on how quickly, or if, the cold air wedge
clears out. If thunderstorm activity isn`t suppressed, there is
the potential for some gusty winds, owing to some decent CAPE
and an impressive 60 kts of shear. High temperatures will be
dependent on the timing of wedge breaking, and have actually
come down a few degrees for our northern and northwestern zones.
Elsewhere, kept things mostly the same as they should break out
of the wedge and reach into the 60s.

High pressure will build across the region Sunday. Winds will
actually be out of the west, so there is a good chance we could
get pretty warm and dry on Sunday. Winds could gust in the 15-20
mph range at times during the afternoon hours. The best overlap
of dry conditions and gusty winds is actually going to be right
where we should see the most rain in the coming days, so not
seeing any fire weather concerns for this period.

Zonal flow aloft is forecast to develop across the Mid-Atlantic for
the first half of next week as several perturbations traverse the
area. Dry conditions are expected Monday as a weak surface high
slides by to our north. This is followed by a strong shortwave
trough quickly moving from the Midwest to the Mid-Atlantic Tuesday
into Tuesday night. A weak surface low that develops over the
eastern OH valley slides northeast into western PA Tuesday night. An
associated cold front sweeps through our area Tuesday afternoon into
Tuesday night. We could see a few showers develop ahead of the front
early Tuesday, however the best chance for rain looks to be Tuesday
afternoon and evening as the front moves through.

A large surface high builds across the region Wednesday, then slides
off the Carolina coast on Thursday. Dry conditions are forecast on
Wednesday, with mostly dry and breezy conditions for Thursday.

High temperatures next week are forecast to be near normal for most
of the week - in the mid 50s to low 60s, except for 40s along the
Allegheny Front. The warmest day looks to be Monday where most areas
reach the low to mid 60s. It is a similar story for overnight lows
that are forecast to range from the mid 30s to lower 40s. The
Alleghenies could see below freezing temps Tuesday and Wednesday
