.SYNOPSIS...
A strong frontal system will bring drier and much cooler weather
to the region. The first half of this week will be dry and
unseasonably cool. The second half of the week will warm up with
chances for showers and thunderstorms returning.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
1820Z Radar shows scattered showers forming across central PA.
An isolated thunderstorm is glancing the far southwestern corner
of the Alleghenies. Expect showers and storms to increase in
intensity through the second half of the afternoon and through
the early evening hours. The front is driving into western PA
with the best forcing south of the Mason Dixon. However the best
heating, along with the highest dewpoints has been through the
Lower Susq. So expect that region to have the best chance for
showers and thunderstorms. Hence why a slight risk for the
eastern portion of the central PA remains in a slight risk. CAPE
is fairly marginal, but around 700 J/kg so should be enough to
spark a storm. the issue with forming significant storms is the
weak shear. The main threats are wind and hail. Some heavy rain
is possible in the east, so there is a small chc of excessive
rain as well.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH 6 PM MONDAY/...
Any thunderstorms should weaken shortly after sunset.
Dry air spreads across all the area overnight with dewpoints in
the 30s over about half of the area by morning. Some clouds do
come back into the NW and wind is at least 5 MPH and increases
through the night, so frost is unlikely. Mins should be in the
l50s SE and just into the 30s in the coolest places of the NW.

Maxes on Monday will be well below normal, by about 17-18 degs
in the NW and around 10 degs in the SE. The dense air will rush
in and make gusts into the 20s. Plenty of sunshine to be had.

&&

.LONG TERM /MONDAY NIGHT THROUGH SUNDAY/...
*Unseasonably cold and less humid air Monday night and Tuesday.
*Frost possible across north central PA early Tuesday morning.
*Unsettled pattern returns Wed-Sun with daily chances for
 showers or thunderstorms.

Monday night the upper trough axis moves to our east leaving
central PA in a dry northwest flow with a surface high center to
our west over Ohio and Southwest PA sinking southeast into West
Virginia. Frost will depend on winds cutting off at the boundary
layer to develop an inversion and a lack of cirrus. Expect
minimum temps in the northern tier to drop into the mid 30s.

By Tuesday afternoon we will be back into a warming pattern.
Some showers and thunderstorms north of a warm front over the
Great Lakes area may move southeast into the northern tier late
in the day. Chances for showers and thunderstorms will move
across central PA Wednesday and Thursday triggered by weak short
waves. Models differ on timing.

Drier weather possible across the north Friday and Saturday with
a surface high building into Central NY. A storm system over the
upper Mississippi Valley has a warm front east across VA. This
may push far enough north to bring a chance of showers or
thunderstorms across southcentral PA.

&&

.AVIATION /19Z SUNDAY THROUGH FRIDAY/...
Showers continue to form across the region. Generally VFR cigs
and vsbys continue. However IFR cigs continue at BFD. These
should continue this afternoon. MVFR cigs have formed at JST due
to the low level flow. Expect periods of IFR in TSRA late this
afternoon and early evening. Best chances for this will be the
Eastern TAF sites.

A second wave of showers/isolated tstms possible early evening.
However most convection should be over shortly after sunset,
exiting the SE by 01z.

Dry air spreads across the area tonight with enough wind to
preclude any cig/fog restrictions from developing, keeping
entire area VFR. Some clouds impact the northern mountains on
Mon, but overall a VFR day in store as winds pick up to 10-15
mph with gusts to 20-25 mph before diminishing Mon eve.

.Outlook...

Mon-Tue...No sig wx.

Wed-Thu...Cig restrictions poss NW. Sct showers/t-storms bring
local restrictions areawide.

.CTP WATCHES/WARNINGS/ADVISORIES...
None.
