.SYNOPSIS...
A north/south ridge of high pressure will build east across
the Commonwealth for tonight and Tuesday. Low pressure will
track north of the region late this week bringing a brief shot
of much milder air for Wednesday on a gusty southerly breeze.

The cold front trailing south from the low will push east
through Pennsylvania on Thursday. An active and gradually cooler
pattern follows with a couple of fast-moving systems moving
through. The potential exists for an early Spring snowstorm
across much of Central PA late next Monday into early Tuesday.

&&

.NEAR TERM /UNTIL 6 AM TUESDAY MORNING/...
Extensive and stubborn, but generally shallow and non-
precipitating stratocu clouds covered the bulk of the state
within a well-defined 925-850 mb thermal trough in the wake of
yesterday`s cfropa and severe weather episode.

HREF and BUFKIT multi-model timesections of RH indicate a
gradual breakup of the CAA clouds later this afternoon and
evening.

NW winds will be moderately gusty (into the low- mid 20s KTS)
through 22Z before dissipating.

Temps will struggle to reach the mid over the high terrain of
the North and West, with low 40s to low 50s respectively from
the Central Ridge and Valley Region to the Lower Susq Valley.

Clearing will develop early tonight as the trough axis moves to
our east and the sfc ridge axis moves in. Just some small
patches of alto cu will be drifting east across the state.

The WAA aloft pushes temps at 8H into the +2 to +4C range
across the CWA overnight, and continues into the upper single
digits by day`s end. The clearing and calming wind should help
temps get into the 20s and lower 30s.

&&

.SHORT TERM /6 AM TUESDAY MORNING THROUGH TUESDAY NIGHT/...
A nice rebound in temps lie ahead for our Tuesday creating a
quite comfortable mid March day for some outdoor recreation or
accomplishing some yard work given abundant sunshine and light
wind.

Look for high temps to reach the upper 50s mid 60s, which will
be 8-13 deg F above normal.

Variable amounts of cloud cover (though still mainly SCT) for
Tuesday night with min temps 10-15 deg f warmer than Monday
night, (upper 30s to low 40s).

&&

.LONG TERM /WEDNESDAY THROUGH MONDAY/...
Another deep low will track northeast from the central Great
Plains on Wednesday, resulting in another run of 70 degree
weather. The source region for this airmass is the southwest
states, where it has been abnormally dry. Expect Wednesday
to be warm, dry, and windy. I could see going a bit higher
with temperatures, if the system trends deeper, one could
see temperatures being a bit higher. Moisture limited at this
point, so severe with cold front early Thursday not likely at
this point. Also time of day, 12Z Thursday. The event yesterday
had limited heating, but much higher dewpoints. Also very strong
shear yesterday. Had a decent amount of rain on Sunday, so fuels
not so dry now, will see how things look like as we get closer
to mid week.

For late Thursday, like the current system, this system slows
as it nears the coast. Thus showers could linger longer.

For next weekend into early next week, trend toward colder
weather again, along with some signal for more winter weather.
Welcome to Spring.

&&

.AVIATION /20Z MONDAY THROUGH SATURDAY/...
Widespread MVFR stratocu cloud bases will cover the Central and
Northern Mtns including the Laurel Highlands through 22Z today
as a cold pool a few to several KFT AGL drifts overhead.

Drying downsloping NW flow will lead to higher sct-bkn cloud
bases (035-045) across the Lower Susq Valley into the early
evening.

Clouds gradually erode from SE to NW late today/early this
evening with all TAF sites expected to be VFR before dusk.

Northwest winds will be sustained at 10 to 15 knots, with gust
of 20 to 25 knots likely through 22Z.

Surface and upper level ridging builds in tonight and will
clear out the clouds. VFR conditions under mainly clear skies
with diminishing NW winds are expected across all of Central PA
after 00Z Tuesday.

Outlook...

Tue...VFR with lighter winds under an area of high pressure.

Wed...VFR. However, southerly winds will gust between 20-30 mph
during the late morning/afternoon hours.

Thu...Showers overspreading the area from west to east.

Thu night/Fri...A few snow showers near BFD early, becoming VFR
during the afternoon. Gusty NW wind 25 to 35 mph.

Fri afternoon-Sat...lighter wind and VFR.

&&

.CLIMATE...
A record rainfall for 16 March was set at Williamsport: 1.37"
(old was 1.20" in 2007)

&&

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