Area Forecast Discussion National Weather Service State College PA 719 AM EDT Fri Aug 14 2020

SYNOPSIS. A stationary front will remain draped across southern Pennsylvania today. A wave of low pressure will ride along this boundary over the weekend, passing just south of the state, then a cold front is likely to push across the region Monday.

NEAR TERM /THROUGH TONIGHT/. Will maintain just a slight chance of a shower early this morning across the southeast part of the forecast area, where high pwat air mass and lingering instability remain per 09Z SPC mesoanalysis. Elsewhere, have dropped POPS to zero early this morning across the northern half of the state, where much drier air resides.

Model soundings indicate any morning low clouds/fog should give way to partly sunny skies later today. Expect scattered, diurnally-driven convection to form during the afternoon over the southern half of the state, in moderately unstable air mass along and south of remnant frontal boundary. Have placed the highest POPs of around 50pct along the Mason Dixon Line, where pwats are highest. Weak winds aloft and 0-6km shear only around 15kts indicate any storms will be of the pulse variety with little risk of severe weather.

Dry ground and a decent amount of sunshine should result in another warm day relative to climatology across the northern half of the state, with highs in the upper 80s possible in the valleys along I-80. More cloud cover and scattered convection should hold readings close to average across the southern counties.

Any showers/storms across southern Pa should die with loss of heating this evening, then expect dry weather the rest of the night. An approaching upper trough and surface low over the Ohio Valley will spread increasing clouds into the region overnight, with an outside chance of a shower reaching Somerset County by dawn.

SHORT TERM /SATURDAY THROUGH SUNDAY/. A slow moving shortwave and associated wave of low pressure is progged to track eastward from the Ohio Valley this weekend. Significant model spread/forecast uncertainty remain with regard to how far north this feature and its associated rain get in Pa. However, all guidance favors the highest POPS across the southern tier counties late Saturday into early Sunday in association with passage of anomalous easterly low level jet.

With surface low tracking south of the state and all guidance showing relatively stable air over Pa, anticipate a stratiform rainfall, rather than convection, and little risk of flooding. The bulk of latest guidance indicate 24hr rain amounts of around an inch or so are possible across the southern counties.

LONG TERM /SUNDAY NIGHT THROUGH THURSDAY/. A cold front is progged to sweep through the Commonwealth Monday, marking the end of an unsettled stretch and ushering in cooler and drier weather.

The Climate Prediction Center 6-10 temperature outlook favors below normal temperatures in central PA. This will be a welcome relief after a prolonged stretch of warm weather. Additionally, the arrival of high pressure by the middle of next week seems to favor a drier than normal stretch for a little bit.

Precipitation chances ramp up again across the southern tier by late week, but no significant impacts are expected.

AVIATION /11Z FRIDAY THROUGH TUESDAY/. After areas of MVFR fog, today looks mainly dry, similar to what we occurred yesterday, thus only used VCSH across the south.

More in the way of widespread showers possible for later Saturday into Sunday Night, but still a ways out. Much of our area could remain between systems to the southeast and southwest of our area.

Outlook .

Sat-Sun . More in the way of widespread showers possible. Mon . Still a chance of showers and storms. Tue . Clearing skies.

CLIMATE. A daily record high temperature of 87 degrees was tied at Bradford on 8/13. The previous record was set in 1988.

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.
