002 FXUS61 KCTP 100743 AFDCTP Area Forecast Discussion National Weather Service State College PA 343 AM EDT Mon Jun 10 2024 .SYNOPSIS... * A cold front will pull east of the area overnight, ushering in a reinforcing shot of cooler air. * Highs on Monday will be 5F to 15F below average for mid-June. * Temperatures will be on the rise through the end of the week as high pressure brings a stretch of rain-free weather with relatively low humidity, light winds, and plenty of sunshine. && .NEAR TERM /UNTIL 7 AM THIS MORNING/... Lingering showers are quickly diminishing during the late evening hours, and should dissipate completely overnight. A reinforcing shot of cooler air will be ushered in overnight behind a secondary cold front, allowing low temperatures to drop into the 40s in the northern tier and the mid to upper 50s in the southeast. && .SHORT TERM /7 AM THIS MORNING THROUGH 6 PM TUESDAY/... On Monday, the approach of a potent shortwave aloft will support more clouds than sun over the higher terrain along with isolated showers across the northern mtns. Monday will be the coolest day of the week, as temperatures struggle to reach 60 degrees across the northern tier. Even the Lower Susq Valley should only top out in the mid 70s. These high temperatures will be 5F to 15F degrees below average for mid-June. Another cool night is in store for Monday night with lows ranging from the mid 40s across the Allegheny Plateau to the mid 50s in the Lower Susquehanna Valley. && .LONG TERM /TUESDAY NIGHT THROUGH SUNDAY/... Upper-level troughiness will persist over the northeastern United States into Tuesday, before the upper flow should become more zonal for the second half of the week. This will allow the cool temperatures early in the week to moderate significantly during the second half of the week. It looks like Thursday and Friday will be downright summer-like, with highs topping 80 degrees areawide and even approaching or topping the 90-degree mark in the valleys of south-central Pennsylvania. The next chance of showers and storms will be Friday, as a cold front drops southeastward from the Great Lakes. High pressure should build back in for next weekend, with a brief cool down expected on Saturday before temperatures begin another upward trend on Sunday. && .AVIATION /06Z MONDAY THROUGH FRIDAY/...

A cold front will bring a reinforcing shot of cooler air and considerable cloudiness this morning. There is a high chance (~90%) that ceilings over the northwestern highlands (BFD) will remain at least MVFR through daybreak this morning, with a ~40-50% chance of IFR ceilings. Restrictions will likely last through much of the day. Farther to the south and east, VFR ceilings are expected to prevail. Could see some patchy valley fog where skies remain mostly clear and winds subside, but not currently anticipating this at any TAF site. Northwest winds will gradually diminish this afternoon as high pressure builds in across the Great Lakes. Outlook... Tue-Thu...Predominantly VFR w/ no sig wx expected. Fri...Restrictions possible if afternoon/evening CB/TSRA develops.
