Area Forecast Discussion National Weather Service State College PA 406 PM EST Thu Dec 12 2019

SYNOPSIS. Fair weather pattern today will turn stormy Friday through the weekend with risk of icy spots, heavy rain, and lake effect snow. Temperatures will trend milder into Saturday before gusty winds direct colder air back into the region by Sunday. Winter weather threat continues for Monday into Tuesday with the potential for snow and ice accumulation.

NEAR TERM /UNTIL 6 AM FRIDAY MORNING/. Expect a general increase in cloudiness through tonight. Tricky forecast heading into early Friday morning with potential for light ice accumulation across parts of south central PA.

SHORT TERM /6 AM FRIDAY MORNING THROUGH FRIDAY NIGHT/. Increasing southerly flow ahead of an amplifying upper trough and low pressure system will gradually spread precipitation northward into retreating cold air damming surface ridge early Friday. Hires models suggest some patchy freezing drizzle is possible during the predawn hours Friday over south central PA. Confidence is low at this point, but any ice could result in high impact to AM commute. HREF and NBM show light QPF spreading north of the PA/MD line after 12Z. The timing/onset of precip in the 12Z to 18Z window is critical for ice threat with ramp-up of POP/QPF coincident with sfc temps climbing just above freezing. Considered an advisory in collaboration with PBZ/LWX MD zones but overall confidence is just not there yet.

Continued to trend max temps Friday on the low-side or below NBM given moisture overrunning the cold air damming pattern early in the day. Temps will be warm enough for rain in most areas by 00Z Saturday. The western Allegheny ridgetops could see freezing rain risk extend into early Friday night. Soaking rain is expected Friday night into early Saturday morning with a narrow diurnal range over the 24 hour period. Highest QPF between 0.50 to 0.75 inches is forecast over east-central PA.

LONG TERM /SATURDAY THROUGH THURSDAY/.

*Heavy rain possible (1-2 inches) in east-central PA Friday night into Saturday *Period of snow with higher amounts in the NW mtns Saturday nightinto Sunday. *Mixed precipitation likely later Monday into Tuesday; potentialfor winter weather should be monitored

Low pressure system will draw deep moisture/above normal PW northward into the area Friday night resulting in widespread moderate to briefly heavy rainfall.

Models have some disagreement on timing and intensity. However, given an adjustment to the NBM. The Storm total rainfall should remain in the 1 to 1.5 inches range across east-central PA. Will need to watch for a transition back to snow on the backside of the system as the upper low pivots into the Northeast. Gusty northwest flow in the wake of the system will usher cold air back into the region. Lake effect snow accumulation is likely in the favored upslope high terrain and snowbelts Sat night into Sunday. Due to lake moisture and the strength of flow have increased snow amounts slightly. Temperatures trend colder Saturday to Monday with another winter weather threat early next week. There will be a potential for snow and ice to impact the area later Monday into Tuesday. Updated local winter storm outlook graphics on the web and HWO to reflect the latest trends/probs.Below average temps are forecast into the second half of next week.


AVIATION /21Z THURSDAY THROUGH TUESDAY/. High pressure building into the region will ensure VFR conditions and light wind through this evening.

Outlook.

Fri . Rain/low cigs likely, especially late.

Sat . Rain/low cigs likely, especially early. Windy late.

Sun . Gusty west wind. AM low cigs/snow showers possible W Mtns.
