Area Forecast Discussion National Weather Service State College PA 321 PM EDT Sat Aug 15 2020

SYNOPSIS. A slow moving area of low pressure will track south of Pennsylvania this weekend, then a cold front will push southeast across the state on Monday. An upper level trough is likely to remain just west of Pennsylvania through the remainder of the next week.

NEAR TERM /UNTIL 6 AM SUNDAY MORNING/. Steady light rain continue to fall over the Laurel Highland, South Central Mountains and southern portions of the Lower Susq River Valley, thanks to an elongated shortwave trof approaching from the Ohio Valley and a weak inverted trof/area of low pressure tracking south of the region. Easterly low level jet and plume of highest PW will remain in place across the southern third of PA, where periods of rain will be likely for much of tonight. Sfc ridging extending southwestward from northern Maine will settle across the region tonight, with deep easterly flow over eastern and central PA. Scattered showers appear possible over the Central Mountains which have been especially dry for several weeks. Amounts are expected to be less than a tenth of an inch for most however.

As steadier light rain decreases across the south and southeast, we'll still see light rain showers lingering through Sunday morning thanks to the deep east northeast fetch off the western Atlantic. HREF and NBM guidance indicate totals of perhaps a quarter inch along the Mason Dixon Line by the time rain tapers off Sunday afternoon.

Precip chances fairly low elsewhere after diurnal activity peters out this evening across the northeast. Showers may also be hit and miss over the NW Mountains into this evening, and mainly dry elsewhere.

SHORT TERM /6 AM SUNDAY MORNING THROUGH 6 PM SUNDAY/. Sfc low tracks off the Delmarva on Sunday, and expect brightening skies by Sunday afternoon, especially over the northern and western counties. However, a strong shortwave tracking across the eastern GLAKS may produce afternoon showers and perhaps a thunderstorm mid to late afternoon over the northwest.

Easterly flow off of the Atlantic and lingering cloud cover over the southeast counties will maintain cool conditions Sunday, with afternoon readings only in the 70s in most spots.

LONG TERM /SUNDAY NIGHT THROUGH SATURDAY/. A dying cold front will push into the region Sunday night, as parent shortwave lifts north of Pa. Despite a lack of large scale forcing, there are low POP chances for showers with the front . best chance across the northern tier.

Diurnal heating, combined with approach another disurbance is likely to cause convective development over northern and eastern Pa on Monday afternoon. Modest capes noted in the model guidance, but decent mid level flow and 0-6km shear support a marginal risk of severe weather per latest SPC outlook.Tuesday still looks dry, as low-pwat air briefly works in behind cold front with northwest flow aloft. Another front moves into PA Wednesday night and Thursday bringing chances for scattered showers and thunderstorms but not like enought to bring any relief to the drought over the central counties. Temperatures look to be near seasonal norms Tuesday- Friday. Friday will be dry under high pressure.

AVIATION /19Z SATURDAY THROUGH THURSDAY/. Mainly VFR conds all day across the east and north. MVFR south with -shra through tonight. Isold MVFR far northeast through early evening. MVFR cigs prominent for most from later tonight along with local IFR in low clouds/fog through Sunday morning. MVFR cigs last through midday tomorrow with best chance of showers in the morning.

Outlook .

Sun . Reductions poss in showers/storms. Mon . Still a slight chance of showers/storms. Tue . Generally VFR conds. Wed . A few showers and brief reductions poss across the SE.

CTP WATCHES/WARNINGS/ADVISORIES. None.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
