SYNOPSIS. High pressure will track east of the area this evening. A weak area of low pressure lifting up the east coast and an upper level disturbance approaching from the Ohio River Valley tonight into Saturday will bring wet snow or mixed precipitation, changing to some rain showers Saturday morning. Light snow accumulations of mainly an inch or less are expected by sunrise Saturday.
An area of high pressure will bring fair and dry weather for Saturday afternoon and the first half of Sat night. Another weak area of low pressure and associated warm front will bring periods of rain Sunday as it pass just south of Pennsylvania. Colder temperatures will work into the area late Monday into Tuesday.
NEAR TERM /UNTIL 6 PM THIS EVENING/. All guidance tracks a weak area of low pressure up the east coast late tonight into Saturday. Although the large scale forcing looks unimpressive, the combination of the weak low and anomalous high pressure off of the New England coast will result in an increasingly moist southeast flow overrunning a relatively cool, stable air mass across Pa. At 03Z, light precipitation has overspread southern Pa and near term models indicate it will reach the northern tier around 06Z.
Model thermal profiles and latest surface temps suggest precip will begin as light rain in the valleys of southern Pa this evening then change to snow due to evaporational cooling. A transition from snow to rain is expected across the state from south to north late tonight, as warmer air works in.
The best chance of a light accumulation of an inch or two of snow is over the high terrain of central and northern Pa, where orographic forcing will be the greatest and where surface temperatures are likely to be just below freezing. Elsewhere, surface temperatures above freezing should limit accumulations to a coating at best. Only spotty trace amounts of fzra are expected on some ridgetop areas, and collab with BGM and PHI yielded consensus to hold off on any headlines.
The deepest moisture is progged to shift east of the region by 12Z Saturday. However, a nearly saturated 0-1km layer, supports lingering light rain/drizzle during the morning hours. Expect brightening skies during the afternoon, as weak low lifts into New England and boundary layer flow shift from southeast to west across Pa.
Low level chilly air should be scoured out with arrival of occluded front, resulting in temperatures rising well above seasonal averages during the afternoon. Latest NBM supports highs from the mid 40s over the northern mountains, to the mid 50s in the valleys of southern Pa.
SHORT TERM /6 PM THIS EVENING THROUGH MONDAY NIGHT/. Mainly dry Saturday night. Looks like precipitation holds off until Sunday morning across northern PA, when temperatures can edge back above freezing.
Another fast moving system passing south of the area on Sunday will bring a quick half inch of rain to the southern PA on Sunday. Rivers could rise about 2 feet. Less rainfall across the north, where the snowpack is deeper. Rain and snow could result in some fog at times.
A stronger cold front will drop southeast into the northwest late Monday. I did up the chance of snow showers late some.
LONG TERM /TUESDAY THROUGH FRIDAY/. High confidence of fair and seasonably chilly weather Tuesday, when all guidance tracks surface high and low-pwat air mass across Pa. The bulk of medium range guidance tracks a southern stream shortwave south of Pa Wednesday, probably too far south to affect the forecast area. However, enough uncertainty to maintain low POPs for a bit of either rain or snow.
Latest ECENS and GEFS support fair and mild conditions Thursday associated with approaching high pressure and a flood of pacific air across the lower 48. Uncertainty ramps up by late next week. Have followed the bulk of guidance, which supports a cold front passage and a chance of rain/snow showers Friday. Latest GFS maintains above average 500mb heights and fair weather across the area.
AVIATION /09Z SATURDAY THROUGH WEDNESDAY/. IFR cigs are widespread across central PA as of 09z, although a few sites are occasionally bouncing up to low-end MVFR cigs. Steady precipitation is confined to locations from the Susq Valley eastward, with light snow across the north and light rain across the south.
Steadier precip will pull northeast of the area this morning and winds will gradually become more westerly, allowing cigs to begin to improve to the southeast of the Allegheny Front. Low cigs and scattered showers will linger the longest across the western highlands /BFD and JST/.
Outlook .
Tonight-Sun . Another round of steady rain will develop from southwest to northeast tonight and continue into Sunday.
Monday-Mon night . Lingering showers tapering off early Monday. Snow showers possible Mon eve/night across nrn PA.
Tuesday . Generally VFR.
Wed . Light rain or wintry mix possible across far south.
CTP WATCHES/WARNINGS/ADVISORIES. None.
