Discussion

KEY MESSAGE 1: Rain-free conditions will persist through the end of October and possibly the first day of November

Cold front entering wrn NY and headed our way. It should pass through during the evening and early part of the night. Expect no precip from the clouds it generates, as there is only limited moisture with it. The high pressure behind it is slightly milder than the current airmass. Thus, temps and dewpoints should not be as low for the next couple of days as the front stalls off to our south. It should return northward as a warm front Wed, but should again only make clouds for Central PA. The next airmass does slide eastward instead of stalling overhead, and will help to set up a return, moist-er flow from the SW. But, it will take a day or two to bring up enough moisture to build up enough to make rain. It looks like Saturday night or Sunday would be the next chc for precip.

Aviation

Clear skies dominate PA today after this morning's fog. A weaker inversion over the western terminals may allow for a few gusts of wind around 15kts or so at BFD and JST. Aside from that, generally calm conditions for the rest of the day.

A cold front will pass through PA tonight where winds will take on a more northerly tilt behind it into tomorrow. Some lower clouds trail behind this front, however with the lack of moisture to work with, widespread restrictions don't look likely. The main areas to watch for MVFR restrictions at this time are the western terminals BFD, JST, and AOO where latest guidance has the highest probabilities for sub 2kft ceilings. This chance is around 80% according to HREF guidance at BFD where confidence is highest, so introduced a few hours of overnight MVFR there.

Outlook...

Tue...MVFR cigs possible in the north and west early, trending VFR.

Wed-Thu...VFR likely.

Fri...MVFR cigs possible mainly in the north and west due to a cold front.
