Area Forecast Discussion National Weather Service State College PA 818 PM EDT Sun Jun 23 2024

A cold front over the Great Lakes will sweep eastward across Central Pennsylvania this evening. A second cold front will push across the region late Wednesday, then a building upper level ridge is likely over the Mid Atlantic toward next weekend.


Real cold front is passing through BFD at this time. Dewpoints aren't any lower behind it, but it is the best wind shift and pressures are rising N of the feature. Convection ahead of the front in the warm sector is now organizing into a couple of lines after previously having plenty of shear and many rotations in individual cells. The unusual heat has been knocked down in the NW half of the CWA, and is about to be dropped in the SE as these storms move through. The SVR Watch for the area is being trimmed as the last line of strongest storms moves past. Still good inbound velocities with that line. As the storms get farther S/E, they may flare up again as they tap the best juice of the event.

After they pass through, the wx will improve overnight.
Dewpoints dip into the m50s in the N and some wind should help fog be a low probability. But, the NW and Laurels may be the places (if anyone can) to get a little fog by morning.

Relief from the heat comes Monday behind the upper trough with sfc dewpoints dropping into the 50s. A tight pressure gradient and steep lower tropospheric lapse rates should result in a very breezy Monday by late June standards. Bukfit soundings support afternoon wind gusts in the 25-30kt range over much of the region, which is significantly higher than NBM guidance.

Fair and seasonable weather with diminishing winds are anticipated Monday night, as high pressure builds into the state. Latest NAMNest and SREF prob charts target the Alleghenies for late night valley fog.

A warming trend emerges on Tuesday as surface high pressure builds across the Mid-Atlantic. Despite the warm-up into Tuesday, MaxTs in the lower 90s across portions of the Lower Susquehanna Valley will be the ceiling in this forecast cycle, where 10-20% of ENS members outline temperatures exceeding 90F during peak warming hours with less than 10% of GEFS members outlining temperatures exceeding 90F.

Surging PWATs ahead of a sfc cold front begin to enter central Pennsylvania late Tuesday evening into Wednesday morning, where chances of precipitation return to the area. Deterministic model guidance has notably shown less coverage in precipitation Tuesday evening, and have limited PoPs towards the northern tier where the best moisture and forcing will be available. PoPs will begin to expand areawide through Wednesday, especially during the afternoon/evening hours where the best daytime heating will be available ahead of the cold front.

Showers and storms will gradually exit to the the southeast on Wednesday night as high pressure builds in. The midweek cold front will reset the cycle similar to what today's cold front will do and usher in a similar stretch as Monday & Tuesday. Thursday and Friday will consist of about 48 hours of lower dewpoints, temperatures closer to average for this time of year, and plenty of sunshine. Afternoon highs in the 70s and 80s, overnight lows in the 50s and 60s (perhaps even upper 40s in the northern mountains Friday morning), and dewpoints below 60F will feel especially good with the persistent stretch of heat.

As high pressure shifts to the east on Friday, southerly flow will support increasing temperatures and moisture into the weekend. The chance for showers and storms will also ramp up Saturday and Sunday as a warm front lifts across the region.

Multiple rounds/lines of storms are expected today across the region. The first round of showers is across northwest PA at 11AM and has struggled to produce lightnign at this point. That line of showers will begin to intensify during the early afternoon hours ahead of a cold frontal passage. There is higher confidence in SHRA/TSRA impacts at airfields across central PA after 18Z with continued daytime heating ahead of the front.
While the bulk of the thunderstorm activity will be focused along the cold front this afteroon, a few storms may develop in the Lower Susquehanna Valley ahead of the main line and bring restrictions to MDT/LNS between 18 and 20Z.

While ceilings will likely remain VFR across the east through the entire TAF period, most guidance suggests that MVFR ceilings will develop west of UNV as the storms move in. Brief periods of IFR will be possible in any thunderstorms. The HRRR suggests around a 50% chance that these low ceilings stick around through most of the night at BFD and JST as winds shift to the west behind the front.


Mon...Predominantly VFR, with brief restrictions possible in scattered SHRA/TSRA as a cold front crosses the area.

Tue...VFR, no sig wx expected.

Wed...Restrictions possible in TSRA.

Thu...AM SHRA/TSRA with restrictions possible, drying out late.

A heat wave will continue through the weekend with near-record temperatures forecast in some locations on Sunday.
