NEAR TERM /UNTIL 6 AM THIS MORNING/
Still a few pockets of stratocu streaming off of Lake Erie in the cool channeled northwest flow around a the large cutoff low tracking into southern Quebec. There may still be a few showers reaching the ground across the NW and NC mountains through 06z.
Winds diminish late tonight for the valleys, but very dry air mass should preclude much in the way of fog formation. Patchy fog is most probably over my northeast counties, but still unlikely there. Min temps will dip to the U30s for the coldest, rural, valley spots in the nrn tier. The little bit of wind should be enough to keep them without frost.

SHORT TERM /6 AM THIS MORNING THROUGH 6 PM MONDAY/
A fair-weather September day for Central PA as high pressure builds into the ern CONUS. Gradient westerly wind still progged to be 10G18KT for most of the CWA on Sunday. RH dips to near 30pct in the srn tier as temps warm near 70F in the valleys, but close to 60F on the highest elevations of the Laurels. Nrn tier will also be in the L60s for maxes.

LONG TERM /MONDAY NIGHT THROUGH SATURDAY/
Surface high pressure building into PA will provide dry weather for this entire week and possibly even beyond given the pattern that is setting up. Calm winds and clear night skies will also allow for the possibility of morning fog to develop throughout the week within the valleys of central PA. Temperatures will start the week a bit below normal before a gradual warming trend begins as the upper trough moves away and 500 mb heights begin to rise. Temperatures will increase a few degrees each day with highs in the upper 70s and low to mid 80s by Wednesday.
Widespread mid 80 high temperatures are expected by the end of the week. Next week looks very similar to this week with chilly nights with valley fog, comfortable/low humidity afternoons, and plenty of sunshine.

AVIATION /06Z SUNDAY THROUGH THURSDAY/
The gusty northwesterly wind of earlier has diminished to 5-10 kts and should remain there overnight. Predominantly VFR conds were found across central PA, although the western highlands (JST/BFD) are occasionally seeing BKN MVFR cigs with an upsloping flow. Expect the continued northwesterly breeze and falling dewpoints to preclude much in the way of fog formation overnight.

A mostly sunny Sunday is expected with widespread VFR conds across central PA. The northwesterly breeze will become gusty once again, and we could see gusts of 15-20 kts by aftn.
