000 FXUS61 KCTP 151550 AFDCTP Area Forecast Discussion National Weather Service State College PA 1150 AM EDT Thu Mar 15 2018 .SYNOPSIS...
-- Changed Discussion --
Cold northwest flow will continue over the local area through the end of the week. Drier conditions will try to visit the region Friday night into Saturday. A weak and fast-moving system will pass by mainly to the south of the state later in the weekend. A larger storm system could develop and affect the state in the middle of next week, but getting detailed with the forecast at this point is not possible.

Short wave trough pressing through right now is seen on the WV loop and even a bit on the radar mosaic. Wind shift behind a linear feature rolling into the wrn mtns is only about a 30 degree veer. The squall moving into the western mtns is breaking up some, and the winds just aren`t significant enough to warrant a snow squall warning. Gusts not over 20kts behind the squall at this point. However, stronger gusts are seen from PIT southward, so these could eventually get near 30kts in the Laurels and SC mtns as weak cold advection begins soon and winds align a bit better vertically as they continue to veer very slightly. Clouds not yet into the NE third of the area, but as the disturbance moves across the area this afternoon, the mesoscale lift should increase the clouds and make snow showers likely there. Will mention sct -shsnra in the SE as the downslope should eat up some of the moisture, but we just had a brief drop to about 2SM here at the office in a SHSN. The temps in the SE are near 40, but shouyld cool off some as the showers reach the ground. Don`t expect an accum over most of the SE as most should melt even if it falls as frozen stuff. The car roofs and grassy areas could have a dusting, though. Temps will probably hold steady elsewhere this aftn.

&& .SHORT TERM /7 PM THIS EVENING THROUGH 6 PM FRIDAY/... Even colder air aloft is advected southeast across PA tonight and Friday as upper trof shapens and digs SE from the eastern GLAKS to off the southern New England coast by Friday afternoon. This will bring renewed blustery conditions with still isolated to scattered snow showers...most numerous in the diurnal heating maximum. Highs will be well below normal again on Friday afternoon, ranging from the mid 20s northwest to around 40F southeast. && .LONG TERM /FRIDAY NIGHT THROUGH WEDNESDAY/... Conditions will improve late Friday into Saturday with some moderation this weekend as upper- level ridging across the middle of the country builds eastward. Another trof undercutting the ridge may spread a chance of rain or snow showers into central PA Sat night and Sunday. && .AVIATION /16Z THURSDAY THROUGH MONDAY/... Most of the lower clds gone now. Minor changes to the 12Z TAFS. Earlier discussion below. Not much going on at 5 AM here...but expect more snow showers later today and early winds shift back to the northwest. Winds will be gusty at times. Improving conditions for the deep storm continues to move away from the area. Outlook... Sat-Sun...No sig wx expected. MON...Mainly VFR. Risk of SN/RA developing late day and night. && .CTP WATCHES/WARNINGS/ADVISORIES... None. && $$ SYNOPSIS...DeVoir NEAR TERM...Dangelo SHORT TERM...DeVoir LONG TERM...DeVoir/Ceru AVIATION...Martin is the U.S. government's official web portal to all federal, state and local government web resources and services.
