Area Forecast Discussion National Weather Service State College PA 858 PM EST Sun Dec 8 2019

SYNOPSIS. After a fair weather weekend, a volatile and stormy pattern is expected during the second week of December. Temperatures are forecast to surge well-above normal Monday and Tuesday, followed by a sharply colder trend Wednesday into Thursday. The brief warm-up will be accompanied by periods of rain which may end as light snow late Tuesday night. A mid to late week drying trend will likely reverse by next weekend with another complex storm system on the horizon.

NEAR TERM /THROUGH MONDAY/. Clouds increasing this afternoon, as moisture starts to work toward the area from both the west and southeast. The NAM shows some spotty QPF across the far northwest toward 00Z. Low levels are quite dry, so hard to buy into this. But approaching storm system will bring steadily increasing PoPs later tonight into early Monday morning.

Main concern will be the object temperatures toward sunrise on Monday, which may be cold enough in a few spots in the central and NE mountains to bring a brief shot of light freezing rain at the onset. That said, sfc temps generally AOA 32F suggest little to no impact as predominant ptype becomes rain into later Monday morning.

As surface low tracks NE across the Great Lakes on Monday, a mild and wet day will be in store.

SHORT TERM /MONDAY NIGHT THROUGH TUESDAY NIGHT/. Rain will continue Monday night into Tuesday as mild airmass ahead of an approaching cold front remains in place. Highest QPF shifts to mainly the western half where 36hr rain totals will be around an inch.

Then the forecast features a shift from mild and west to colder and wintry later Tuesday into Wednesday, as deep cold upper trof centered over Hudson Bay directs cold air across the central and eastern GLAKS and a flat surface wave exits the eastern seaboard. This will turn precip over to some light snow as the colder air sweeps in Tue into Tue night, with potential for a snow band setting up over the SE that could bring a few inches of snow just before dawn Wednesday.

LONG TERM /WEDNESDAY THROUGH SUNDAY/. It will turn sharply colder midweek as arctic air blasts into the region. Temperatures will be on the decline over the NW Tuesday afternoon (non diurnal over the NW half) and drop quickly Tuesday night areawide. There will be some potential for residual water or slush to freeze up quickly by Wednesday. Highs are forecast to drop by 20-30 degrees between Tuesday and Thursday, with minimum wind chills in the single digits and teens Thursday morning.

Strong 1040+mb high pressure moves NE across the region Thu/Fri followed by another system which could bring rain or mixed precipitation Friday into Saturday.

AVIATION /02Z MONDAY THROUGH FRIDAY/. Low pressure approaching from the midwest will spread lowering cigs and rain into the region late tonight and Monday. Latest model soundings and SREF probability charts support a fairly high confidence of IFR conditions developing between 12Z-15Z over most of the area. The one area of less certainty is over the Laurel Highlands (JST), where a progged southerly flow is unfavorable for low cigs. Strong southwest winds aloft, combined with much lighter surface winds, will set the stage for low level wind shear across much of central Pa late tonight and Monday.

Outlook.

Tue . AM low cigs/shra, mainly N Mtns. Evening light snow possible southeast Pa.

Wed . AM light snow possible southeast Pa.

Thu . No sig wx expected.

Fri . Low cigs possible, especially late.

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.

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