Area Forecast Discussion National Weather Service State College PA 822 PM EST Sun Feb 12 2017 .SYNOPSIS... A potent storm system with multiple facets and threats will move through the region late today through Monday. High pressure will return with fair and mild conditions for Tuesday with much lighter wind. Another potent upper level disturbance and surface cold front will move southeast from the Upper Great Lakes and bring the cold air back to the state for Wednesday through Friday. Abnormally warm air looks like it returns for next weekend. && .NEAR TERM /UNTIL 6 AM MONDAY MORNING/... A line of low topped thunderstorms has formed over SWRN Pa and has been associated with sporadic wind damage. The main surface low is now south of New England and deepening rapidly. Cold air is now pouring into the local area and the line of convection is associated with a weak secondary trof in the colder airmass. Surface winds not associated with the gusty thunderstorms will be on the increase as the gradient tightens and a strong isallobaric pressure rise slides across the region. Bufkit soundings support frequent gusts developing on the 35-50 mph range over the next several hours and continue into Monday. The QPF for the rest of today from some bands of fast moving showers will be less than one tenth of an inch, and the combination with limited additional snowmelt/runoff will not be enough to cause any flooding problems. As the colder air pours into the region and we develop a deep NW flow over the Gr Lakes, lake and orographically enhanced snow showers will be on the increase into NWRN Pa and the Laurel Highlands. Snow accumulations over the far NW will be enough to create hazardous travel. There will be a favorable fetch off Lake Erie and there will also be quite a bit of speed shear and gusty winds. Will hold the LES warning to Warren Co for now, and an advisory McKean Co. The fetch is not favorable for heavy snow for much of the area, but the Laurels and their upslope help will probably tack on another 1-3" to the coating which may occur during the push of cold air early in the night. Potter Co and maybe even Elk Co may need an advy for snow eventually if the bands are more persistent than currently anticipated - but confidence is low for that at this time. The bands will be numerous, but also fast moving and a fairly short distance away from the lake. && .SHORT TERM /6 AM MONDAY MORNING THROUGH 6 PM MONDAY/... The wind decreases gradually in the afternoon, but will still be quite gusty (30-35 mph) as the low pulls northeast of Cape Cod. The snow showers also diminish/dissipate fairly quickly as the subsidence inversion base drops steadily. Max temps Monday will be near normal (about 40F) in the eastern valleys with the strong downslope flow and eventual clearing. However, highs will stay 5-10F short of normal elsewhere. && .LONG TERM /MONDAY NIGHT THROUGH SUNDAY/... The winds will gradually slacken Monday night into Tuesday as a ridge of high pressure slides east from the Ohio Valley. An area of low-mid level warm advection-induced light snow may brush the NW mtns Tuesday as another nrn stream wave approaches from the Upper Glakes. This wave of moisture and instability will drop through Tuesday night into Wednesday, though most precipitation should be relegated to the mountains. SFC low has shifted further north with cold air back into the region mid week through the end of the week. Light precipitation possible with another shot of cold air and gusty NW winds through the mtns. The influx of cold air will shift as a ridge will builds in into next weekend. Currently 850mb temps are in the +4C range so expect warmer temperatures. && .AVIATION /01Z MONDAY THROUGH FRIDAY/... A cold front will sweep through central Pa this evening, accompanied by a round of snow showers/squalls across the NW Mtns and rain showers elsewhere. IFR CIGs from IPT south to MDT/LNS will give way to rapid improvement by around 02Z-03Z, as drier air works in behind the front. Main story across the entire region will be the strong, gusty WNW winds following the frontal passage. Model soundings support frequent gusts overnight of around 40kts with peak gusts close to 50kts possible, mainly across southern Pa. Behind the front, model soundings support mainly VFR conditions east of the mountains overnight. However, residual low level moisture ascending the Allegheny Plateau will result in lingering snow showers with occasional IFR VIS reductions at BFD and JST. Gradual improvement is expected Monday, as high pressure approaches from the Midwest. However, MVFR CIGs/flurries appear likely at BFD/JST for much of the day. Bufkit soundings support wind gusts to around 45kts across southeast Pa during the morning (35kts northwest Pa), then gradually diminishing winds toward evening. Outlook... Tue...No sig wx expected.

EVANEGOThe national radar mosaic for the moment the first event began.
2 strong wind. Local standard time, as filed.
Strong winds on the back side of a developing coastal storm blew out a 40-50 foot storefront window on a business on Route 22 in Lewistown.
A 22-year-old man died after a tree branch downed by strong winds crashed through his windshield. The man was driving on Route 944 in Silver Spring Township when the branch struck him in the chest around 2340 EST. He was taken to West Shore Hospital where he died from his injuries.
As the offices recorded each death: direct deaths were caused by the weather itself, indirect ones by something it set in motion.
