DISCUSSION
KEY MESSAGE 1: Extended stretch of dry weather with minor wind impacts from the strong coastal low this weekend
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 WEDNESDAY THROUGH MONDAY/
VFR will prevail tonight through tomorrow across central Pennsylvania given the drier air in place. Ceiling restrictions will be unlikely, as well as fog development due to E/NE flow ranging between 5-10 kts overnight. Thursday daytime winds will increase to between 7-15 kts with gusts up to 25 kts, especially in the Lower Susq Valley. Marginal LLWS could be possible for KLNS and KMDT tonight.
Outlook...
Thu-Mon...VFR favored as a developing coastal low looks to bring subsidence overhead, though -RA and lower cloud ceilings associated with this system may reach our eastern terminals this weekend (20 pct chc).
