.NEAR TERM /UNTIL 6 AM THURSDAY MORNING/...
Cloud-free, very pleasant afternoon/evening across CPA with a
refreshing and gradually decreasing breeze from the northeast.
+MSLP/-PWAT anomalies set the stage for a clear, crisp, and
chilly night with frost formation across north central PA. The
colder valleys in the Laurel Highlands and south central
Alleghenies will likely see at least some patchy predawn/daybreak
frost and have expanded the frost advy to cover these areas.
&&
.SHORT TERM /6 AM THURSDAY MORNING THROUGH FRIDAY NIGHT/...
After a cool start, the Autumn feels continue on Thursday with
high clouds and maxes in the 65-70F range, marking a nadir in
daytime high temps. Another cool and crisp early October
[Thursday] night with partly cloudy skies and lows in 40s.
Friday will mark the start of a prolonged early Fall warming
trend with max temps in the 70s and lows 40-50F. We anticipate
some valley fog both nights with perhaps greater coverage
overnight Friday due to less mid/high cloud cover.
&&
.LONG TERM /SATURDAY THROUGH WEDNESDAY/...
Mostly sunny and very warm days followed by comfortable sleeping
nights over the weekend into early next week. Highs will climb
well above the historical average for early October (+10-15F)
reaching the mid 70s to low 80s. The dry air in place will keep
min temps closer to/but still above climo. No rainfall is
expected Saturday through Monday.
Model and ensemble mean consensus finally bring some rainfall
back into the picture by the middle of next week, with a cold
frontal passage projected around next Tuesday/Wednesday. NBM/WPC
blended QPF amounts within that 24 to 48 hr period are in the
0.10 to 0.75" range from SE to NW - so certainly not a drought
buster we will take what we can get.
&&
.AVIATION /19Z WEDNESDAY THROUGH MONDAY/...
VFR flying prevails for the next several days with light sfc
winds shifting from 060 to 180 degrees by Friday. The odds for
overnight and early morning valley fog formation increase
Thursday night through the weekend.
Outlook...
Fri-Mon: AM fog; otherwise VFR.
