Area Forecast Discussion National Weather Service State College PA 558 AM EDT Fri Apr 16 2021

SYNOPSIS. An upper low over northeast Pennsylvania will slowly push east of the region later today and tonight. A pair of weak shortwaves will lift into the region from the Ohio Valley Saturday evening and Monday, then an upper trough over the western Grt Lks will shift east across Pennsylvania by the middle of next week.

NEAR TERM /UNTIL 6 PM THIS EVENING/. Water vapor loop at 09Z shows upper low over northeast Pa. A deep, moist northwest flow in comma head is currently producing an area of steady rain/snow across the southern tier of New York into parts of northern Pa. Near term model guidance indicates this area of precipitation will shift into northeast Pa later this morning, as upper low edges east. Have ramped up POPs toward dawn across the northeast corner of the forecast area, where model soundings are cold enough for snow over all but the lower elevations within the Middle Susq Valley. It looks like a wet inch or so of snow accumulation is likely by the morning commute over the mountains north of KIPT. Penndot sensors indicate road temperatures are running a few degrees above air temperatures and well above freezing, so don't anticipate any significant travel issues.

Across the rest of central Pa, upsloping flow will yield occasional snow showers early this morning across the Allegheny Plateau, where a light coating is possible by dawn over the highest ridgetops. East of the mountains, only a few light rain showers/sprinkles are expected early this morning across the south-central mountains and Lower Susq Valley.

The coldest air aloft is currently over the region, so don't anticipate temperatures to change much from 07Z readings through dawn, running from the low 30s over the mountains north of KIPT, to around 40F over the Lower Susq Valley.

Upper low is progged to slowly shift east later today along the southern New England coast, with comma head lingering over northeast Pa. Model soundings show a nearly saturated sfc-500mb layer over the northeast corner of the forecast area throughout the day, supporting high POPs, especially over the mountains north and east of KIPT, where orographic enhancement is maximized. Model soundings indicate periods of mainly snow with rain in the valleys will transition to all rain by afternoon, as boundary layer warms. Any light additional snow accumulation should be confined to the hours before 10 am over the mountains north and east of KIPT.

Inversion heights and depth of moisture are progged to be much lower across the rest of the forecast area. However, upsloping northwest flow should yield scattered morning rain/snow showers over the Allegheny Plateau, transitioning to only rain showers by afternoon. Downsloping flow east of the mountains should result in only widely scattered rain showers/sprinkles from south-central mountains into the Lower Susq Valley.

Perhaps the biggest ticket item for Friday will be peak wind gusts in the 30-35 mph range across mainly the SW half of the CWA where the strongest downsloping and deep-layer subsidence will occur beneath the thermally direct left entrance region of a 100 KT jet over WVA and VA.

A pool of unseasonably chilly air aloft and plenty of cloud cover will result in high temps well below seasonal averages today, with afternoon readings peaking from just the low 40s over the northern mountains, to the mid 50s across the Lower Susq Valley.

SHORT TERM /6 PM THIS EVENING THROUGH SUNDAY/. Expect diminishing showers this evening, as the upper low slowly lifts further away from Pa. However, model RH profiles still show a nearly saturated 0-1km layer ascending the Alleghenies, supporting the chance of a few lingering showers or even a bit of drizzle over that part of the state.

Upper ridging is progged to briefly build into the region Saturday, supplying partly sunny skies and milder weather with significantly lighter winds than today. A pair of weak, moisture-starved shortwaves are forecast to lift out of the Ohio Valley Saturday evening and late Sunday, accompanied by the chance of a shower in a few spots. However, most locations should escape measurable precipitation. Partly sunny skies and moderating temps aloft should allow temperatures to return to near seasonal levels Sunday afternoon in the mid 50s to low 60s.

LONG TERM /SUNDAY NIGHT THROUGH THURSDAY/. By early next week, we shed the effects of the retreating trough, but a shortwave may generate a few scattered showers Monday. Then, we finally get a glimpse of "mild" conditions and even some sunshine by Monday evening, with temperatures approaching the 70 degree mark in the Lower Susquehanna Valley by Tuesday afternoon. The sunshine Monday afternoon and warmest temperatures of the week on Tuesday will combine for the two best days of at least the next 7.

Increasing clouds Tuesday night will precede another good chance of rain, and perhaps some snow on Wednesday. Details are still unclear, but QPF amounts should remain low enough to minimize much in the way of accumulation. Then, below- average temperatures return for Thursday as a deep upper trough digs back into the northeast. Model guidance is still a bit variable in how deep the trough will be, and thus how cold temperatures will get. We'll be keeping a close eye on the low temperatures for Thursday morning, which appears to be the best chance for near or sub- freezing temperatures across the Commonwealth. Peeking into the future, the ECENS brings a return of mild, above average temperatures into next weekend, while the GEFS keeps the less-enjoyable weather pattern around for awhile.

AVIATION /10Z FRIDAY THROUGH TUESDAY/. Northwest flow will continue today with upslope clouds at BFD and JST leading to generally IFR conditions, though BFD has been going up to MVFR at times overnight. Along with the northwest flow, occasional rain showers will continue to impact all terminals at times today. Expect IFR to continue at BFD and JST today, MVFR at AOO, UNV and IPT with generally VFR at MDT and LNS. Gusty winds will also pick up during the day today, peaking this afternoon near 30kts.

Outlook .

Fri night . Reduced cigs/vis in NW mountains.

Sat . Improving to VFR areawide.

Sun and Mon . Low cigs possible in scattered showers, mainly over the northern and western mtns of PA. Central ridge and valley airfields should only dip to MVFR.

Tues . Reductions across the northern tier in rain showers late in the day.

CTP WATCHES/WARNINGS/ADVISORIES. None.
