DISCUSSION

KEY MESSAGE 1: Extended stretch of dry weather with minor wind impacts from the strong coastal low this weekend

Another chilly late September night particularly across the northern and western Alleghenies where patchy frost is likely in the usual cold spots. Coordinated with PBZ and LWX on a frost advisory for Somerset County.

A much needed break from the rain (following one of the wettest mid to late summer patterns on record) is expected over the next 7 days across the majority of central PA.

A strong coastal low developing offshore NJ/Long Island/southern New England could bring some light rain to the eastern third of the CWA (mainly east of US-15) later this weekend, but the main sensible weather impact from this system will be from the wind. Breezy conditions are expected Saturday and Sunday with max gusts 30-35 mph range over the higher terrain in the northeast portion of the forecast area.

As the stacked coastal low moves toward the Canadian Maritimes, temperatures are projected to rebound and climb several degrees above the historical average heading into the end of the month.

AVIATION /18Z THURSDAY THROUGH TUESDAY/

VFR will prevail across much of central Pennsylvania through the end of the week. Some patchy valley fog is possible early Friday morning across the western and northern Alleghenies. Marginal LLWS is also expected at KLNS and KMDT. Wind will become the main aviation impact starting Friday and increasing over the weekend. Winds from ~360 degrees gusting 20-30kt.

Outlook...

Sat-Sun...MVFR and pds of -RA possible far eastern airfields.

Mon-Tue...VFR.
