Area Forecast Discussion National Weather Service State College PA 523 AM EST Sat Dec 7 2019

SYNOPSIS. Flurries or scattered light snow showers are likely across the northern tier counties of Pennsylvania early today. Dry conditions with near normal temperatures will follow for the much of the weekend. A warm up along with periods of rain are in store for Monday and Tuesday.

NEAR TERM /UNTIL 6 PM THIS EVENING/. Weak low level cold advection will help to keep a broken to overcast layer of strato cu clouds in place across much of Central and Northern PA through the midday hours as 850 mb temps hover near -10C across the north, and slowly warm a deg or two C over the SW zones (where 850 mb temps this morning will be around -6C).

This will be followed by weak warm advection throughout the blyr late this afternoon with gradual clearing and just some periods of sct- bkn alto cu clouds topping sfc high pressure that will be building east from Ohio.

High temps today will range from the mid to upper 20s across the northern mtns to around 40F in the southern valleys. A northwest breeze at 5-10 mph will become light and variable by dark.

SHORT TERM /6 PM THIS EVENING THROUGH 6 AM SUNDAY/. Dry weather expected for tonight and most or all of Sunday as high pressure slides east across the state. After a chilly start over the NE Sunday morning with temps in the teens, temps will warm to near seasonal normals in the mid 30s (NE) and low 40s (South).

LONG TERM /SUNDAY THROUGH FRIDAY/. Big temperature swings are expected during the period. A significant warming trend is forecast through early next week with max temperature departures +10-15 degrees above normal (widespread 40s and 50s).

Unseasonably mild minimum temps are forecast Monday night with departures on the order of 15-20 degrees above normal as the primary PWAT axis (with values around +2 sigma) slides east across the region.

The mild surge will be accompanied by periods of light to moderate rain Monday and Tuesday. Rainfall amounts between 0.50 to 1 inch are forecast early next week.

The warm air and rainfall will help to melt the snow over the Allegheny Front into the Upper Susquehanna River basin. Areas of fog are likely as the mild air moves over colder ground. Rises on rivers/streams are expected and will need to monitor risk of minor flooding across the northern tier. WPC indicates a MRGL risk of rainfall heavy enough to cause flooding of small streams and poor drainage areas over our far western counties Monday into early Tuesday.

It will turn sharply colder through midweek as arctic air blasts into the region. Temperatures will be on the decline Tuesday afternoon through Tuesday night (non diurnal over the NW 1/2 during the day Tuesday). 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.

There is also a chance that the cold air could catch up to the back edge of the rain and result in a period of snow at the end of the precipitation event on Wednesday. There should be some lake effect snow that develops in the wake of the system, but trajectories appear to be focused more into southwest NY.

The active weather pattern next week may continue into the weekend with the GFS and ECMWF both showing a large, dynamic storm system impacting the region.

AVIATION /10Z SATURDAY THROUGH WEDNESDAY/. TAFS updated here as of 430 AM.

Some lower clouds will be possible across the mountains this morning, otherwise VFR conditions will prevail across the region this weekend.

Wet weather moves in for early next week.

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.
