Area Forecast Discussion National Weather Service State College PA 520 AM EDT Wed May 1 2024

SYNOPSIS
-Areas of dense fog start the day in some of the Central Valleys of the state.

-Warm/dry weather with lower humidity is in store for today and Thursday

-Trending unsettled into the weekend with some periods of rain Sat/Sun

NEAR TERM /UNTIL 6 PM THIS EVENING/
A swath of counties, occupying primarily the Central Ridge and Valley Region of Pennsylvania, will experience areas of dense fog with visbys ranging from 1/4SM to as low as just a few hundred feet in some places. The contributing factors to this fog are Tuesday's rainfall, earlier clearing and still moderately high sfc dewpoints in the Central Ridge and Valley Region and light/variable wind.

As a ridge of high pressure at the SFC and aloft drifts east and over the state today, dewpoints into (or slowly down through)
the 40s with a splendid late morning and afternoon, soaked with sunshine and unlimited visibility.

Comfortably warm high temps will reach the low to mid 70s over the Northern and Western Mtns and upper 70s to low 80s respectively in the Central and Southern Valleys. These readings are +10 to +15 compared to average. Thursday will a few degrees warmer for much of the Commonwealth.

SHORT TERM /6 PM THIS EVENING THROUGH 6 AM THURSDAY/
Mainly clear skies with just patchy late night valley fog tonight as a light west to southwest breeze prevails ahead of a weak and dry secondary cold dropping south from the Lower Glakes and New York State.

Lows temps will range from the upper 40s in the coldest rural valleys of NW PA to the upper 50s on some of the ridges in Central and Southern PA, where a light westerly breeze will keep the Blyr stirred up a bit.



LONG TERM /THURSDAY THROUGH TUESDAY/
Expect nearly a carbon copy of today's (Wednesday's) weather on Thursday with a light to moderately gusty NW wind. Dewpoints lower by a few to several deg F Thursday will translate into afternoon MinRH values in the upper 20s to mid 30s.

Easterly flow begins to take hold on Friday, as high pressure noses down the eastside of the Appalachians. This should result in cooler temperatures Friday, especially across eastern PA.
This setup could also favor low clouds into the middle and lower Susquehanna Valley Friday night into Sat AM.

A frontal boundary will slowly make it's way eastward from the Midwest into the commonwealth Saturday into Sunday, accompanied by an increasing chc of showers and storms.

Passage of the upper trough and associated front should bring drier conditions by Monday of next week, before an approaching warm front could bring a return of clouds and showers/storms on Tuesday.

AVIATION /09Z WEDNESDAY THROUGH SUNDAY/
Low stratus has developed across the Laurel Highlands thanks to a moist, upslope flow. Patchy valley fog has also developed across much of north central PA, due to clearing skies, damp ground and diminishing winds. These will be the primary concerns through sunrise, with areas of locally LIFR vsby and cigs.
Farther to the west, drier air filtering in from the northwest will work against the formation of fog.

Expect quick improvement areawide Wed morning, with building high pressure providing mostly sunny skies and a W/NW sfc breeze of 5-10 kts. VFR conds will prevail with only mid and upper level clouds.

Outlook...

Thu-Fri AM...No sig wx expected.

Fri PM-Sat...Scattered SHRA/TSRA developing from west to east w/ reductions possible.

Sat night-Sun...Widespread SHRA/TSRA expected.
