High pressure will build into the area bringing dry weather and temperatures very close to average for Thanksgiving today. The high pressure ridge will slowly drift over and east of the area on Friday and early Saturday ahead of a frontal system which will bring a chance of precipitation to the area this weekend.

&& .LONG TERM /FRIDAY NIGHT THROUGH WEDNESDAY/...
-- Changed Discussion --
Weak ridging aloft in advance of next system Friday and Friday night. Expect a somewhat milder day Friday, as surface high passes off the coast and return southwest flow ensues. Cold front approaches region on Saturday. Scattered rain showers will likely accompany the front on Sat, followed by a period of lake effect snow showers Sat night into Sunday, as another blast of seasonably chilly air charges across the relatively mild waters of the Grt Lks. ECENS and GEFS both support below normal temperatures Sunday, as deep upper level trough swings over the northeast states. As has been the case all fall, the colder weather will be short lived with dry weather and mild temperatures returning for at least the first half of the upcoming work week.

&& .AVIATION /10Z THURSDAY THROUGH MONDAY/... Bkn-Ovc layer of MVFR to low-end VFR strato cu clouds will persist across the Central and Northwest Mountains of Pennsylvania through the mid morning hours today. Afterward, the low-mid level ridge of high pressure just off to our west will flatten out and drift over the state this afternoon and evening. After the strato cu dissipates later this morning as the mean low level flow backs around to 240-260 degrees, an area of bkn alto cu (based at 080-120 kft agl) and cirrus will slide east from the Ohio Valley and across Central PA and the Susq Valley this afternoon and evening as milder air aloft streams east out of the Upper Midwest. The WNW to WSW winds throughout the TAF forecast period will be generally less than 10 kts. Otherwise VFR conditions will prevail into Friday. The overall pattern favors no big weather systems through the upcoming weekend and into early next week, but frontal passages with limited moisture are expected every few days. Have a good Thanksgiving. Outlook... Fri...No sig wx expected. Sat...Chance of rain/snow showers. Sun...Chance of snow showers across the NW in the morning. Otherwise no sig wx expected.
