Area Forecast Discussion National Weather Service State College PA 322 AM EDT Sat Aug 15 2020

SYNOPSIS. A stationary front will remain draped along and south of the Maryland border for the next few days. A wave of low pressure will ride along this boundary over the weekend, passing just south of the state. A cold front is then likely to push across the region on Monday.

NEAR TERM /UNTIL 8 AM THIS MORNING/. An approaching upper trough and surface low over the Ohio Valley will spread increasing clouds into central and southern Pa overnight, with the chance of a few showers reaching southern Somerset, Bedford and Fulton counties by dawn. Mostly clear skies and a light wind should allow temperatures to fall to around 60F by dawn along the northern tier, where patchy valley fog will be possible. Further south, cloud cover should hold readings in the mid to upper 60s across the southern counties.

SHORT TERM /8 AM THIS MORNING THROUGH 6 PM TODAY/. A slow moving shortwave and associated wave of sfc low pressure will track eastward from the Ohio Valley later today. Easterly low level jet and plume of highest pwats will be trained over southwest Pa, where periods of rain will be likely, mainly during the PM hours. Elsewhere, diurnal heating, combined with approach of shortwave, should cause scattered convection to develop over northern Pa by afternoon. A few rumbles of thunder are possible across northern Pa, but no worries about severe weather given weak flow aloft and meager instability due to increasing high clouds.

All guidance favors the highest POPS across the Laurel Highlands, where moist southeast flow is forced to ascend the higher terrain. Second area of higher POPs will be across the northwest mountains, where more sunshine and resulting instability is expected. Outside of these areas, expect any showers to be hit or miss with many locations remaining dry today.

With surface low tracking south of the state and all guidance showing stable air over southern Pa, anticipate a stratiform rainfall, rather than convection, over the southern counties and little risk of flooding.

Increasing cloud cover and southeast flow off of the Atlantic will result in the coolest day in about a week, with max temperatures ranging from only around 70F over the Laurel Highlands, to perhaps the mid 80s across the Middle Susq Valley.

LONG TERM /TONIGHT THROUGH FRIDAY/. Recent runs of the EC have been very dry for the Sat night-Mon time-frame. With recent model QPF/PoP blossoming, there is some validity to looking at the drier model solution. Moisture just does not seem to get here from the south, and very little will come with the front crawling in from the west this weekend. But, the forecast for likely PoPs in the south and high chcs for the north has been rolling for days. Will not make any large tweaks with this update, perhaps just a 10pct slice off the PoPs as drought only feeding on itself. No moisture in the ground to help juice up the llvls and aid in convection. So, it continues to look pretty dry with only small diurnal chcs in the middle of the week. Temps look like we cool back to normal or slightly below for Sunday, then run about normal for the first part of the week, then rise again to above normals for the latter half of the work week.

AVIATION /07Z SATURDAY THROUGH WEDNESDAY/. Expecting generally VFR conds to persist across central PA overnight, with little more than some high and mid-level clouds passing overhead. Some model guidance is hinting at the possibility of some low cloudiness developing in the southern Alleghenies overnight, in the vicinity of AOO, but have left it out of the TAF for now.

Saturday should start out with VFR conds area-wide, and will probably remain that way all day across the east. However, clouds will build through the day and showers are possible by afternoon across the western highlands.

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.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
