Area Forecast Discussion National Weather Service State College PA 423 AM EDT Sun Sep 19 2021

SYNOPSIS. High pressure moving in will prompt sunny, less humid, and dry conditions across the area until Tuesday. By mid-week, a strong cold front will bring a widespread soaking rain to Pennsylvania. Following the frontal passage towards the end of the week, temperatures will be noticeably cooler for the first few days of fall.

NEAR TERM /UNTIL 8 AM THIS MORNING/. Fog has settled into the valleys of the Northern Tier and SW, along with some scattered low clouds over the middle Susq Valley. Fog is expected to develop in valleys through the rest of the night, especially over the western part of the forecast area where the progged pressure gradient is weakest. Areas in the lower Susq may remain fog free or have limited fog relatively warm air temps and their location to the stronger gradient. The arrival of drier air should allow reading to drop into the mid 40s over the normally cooler valleys of the northwest mountains, while lows in the 60s appear likely over the southern tier counties.

SHORT TERM /8 AM THIS MORNING THROUGH 6 PM MONDAY/. Patchy valley fog could linger until 14-15Z Sunday morning over the northwest mountains per latest SREF and NAMNest. For the rest of the day, expect clear sunny skies and light winds as high pressure and low- pwat air mass build over the state. Ensemble plumes indicate temps will be 6-7 degrees lower than today with highs ranging from the low 70s over the northern mountains, to the upper 70s in the southern counties.

LONG TERM /MONDAY NIGHT THROUGH SATURDAY/. Upper ridging across the Atlantic coast should ensure dry and warm weather for the start of the week. Increased temperatures due to ample warm air advection. Meanwhile, a trough will begin to deepen over the midwest which will be the primary weather producer for the midweek. Max temperatures are expected to be a few degrees above normal for late September, while min temps overnight will be several degrees above normal.

The deep upper-level trough will contribute to a strong surface low pressure system that will enter the region on Wednesday, which also happens to be the Autumnal Equinox. Currently, the GFS is more progressive than the Euro with bringing in the cold front on Wednesday. At this time, it looks like the cold front will sweep over Pennsylvania Wednesday afternoon and evening.

Numerous and widespread showers are expected with the passage of the cold front, which will dump quite a bit of rain over the forecast area. By Friday, ensemble mean QPFs are upward of 1-1.5". Drier conditions expected Thursday and Friday. High pressure will briefly build in behind the front yielding cool weather. Model spread is fairly large on the temperatures during and after the frontal passage, but expect temperatures to feel cooler compared to the warm last week or so. Another upper- level disturbance may lead to showers on Saturday afternoon and evening.

AVIATION /08Z SUNDAY THROUGH THURSDAY/. Fog already filling all the valleys of northern PA and creeping southward a bit. Will hit the fog hard in IPT. The few remaining lower clouds there have moved out, but probably slowed the development of fog.

Wind will be light throughout the forecast period with high pressure overhead. Other than some high clouds to the south of the state, the only other clouds left after the fog/stratus burns off will be a few cu over the Laurels. Sunday night, valley fog will redevelop. The flow returning from the south could bring low stratus into the south-central mtns by sunrise Mon. Those clouds will try to expand into the western mtns.

Outlook .

Tues..SHRA/TSRA possible W, mainly late in the day.

Wed-Thurs . SHRA/TSRA likely. CFROPA.

CLIMATE. Fall Equinox 2021 will be at 3:20 PM (1920 UTC) on Wednesday, September 22.
