.SYNOPSIS...

Look for dry weather with sunny days and clear cool nights this
weekend. Temperatures will moderate significantly on Sunday. 
Aside from light precipitation potential on Monday, a prolonged
period of dry weather appears likely to last until next 
weekend.

&&

.NEAR TERM /UNTIL 6 AM SUNDAY MORNING/...

Skies are clear with winds still gusting 15-25 mph. Gusty winds
will diminish with clear skies and cold temperatures overnight.

&&

.SHORT TERM /6 AM SUNDAY MORNING THROUGH 6 PM SUNDAY/...
Dry weather. Milder air returns aloft and will quickly mix to 
surface during the day with temperatures a good 10-15 degrees 
warmer than today.

&&

.LONG TERM /SUNDAY NIGHT THROUGH SATURDAY/...
Clouds will increase into Sunday night with the next 
frontal system possibly bringing some light precipitation to the
area by Monday morning. Model QPF trends shifted light amounts 
to the south, focusing over the southern 1/2 to 1/3 of central 
PA Monday during the day. Latest NAM has trended colder and has
gone with snow as the precipitation type. This is due to the
marginally cold temps on the northern edge of pcpn in northern 
PA. Have gone with snow through the north though accumulations
will be light at best. Precip shifts to the south with dry wx 
likely Monday night. We are pretty confident in a prolonged 
period of dry wx this period, as large area of high pressure 
dominates the regional pattern. We are also bullish on a warming
trend toward above average temperatures starting around 
midweek, but will need to watch for potential cool-air damming. 
NBM does a decent job in mitigating timing differences with pcpn
associated with frontal system around the end of the month.

&&

.AVIATION /23Z SATURDAY THROUGH THURSDAY/...
VFR conditions this weekend, though gusty NW winds during the
afternoon hours.

An intense low pressure system over the Canadian Maritimes will
maintain gusty northwest winds across central Pa through today.
Bufkit soundings support frequent gusts in the 25-30kt range 
through early this evening. High pressure will build into the 
region this evening, causing winds to diminish. 

.Outlook...

Sun...No sig wx expected.

Mon...AM rain/low cigs possible, mainly N and W Mtns. 

Tue-Wed...No sig wx expected.

&&

.FIRE WEATHER...
Gusty northwest winds 20+ mph and minimum RHs below 30% are 
expected this afternoon. Low RH is also forecast on Sunday, but
with lighter winds. Fine fuel moisture (per coordination with 
fire wx partners) will remain above 10% through the weekend, 
and therefore no fire wx headlines are expected at this time.

&&

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