.WHAT HAS CHANGED...
* Expanded fog/mid morning stratus cloud cover in the Valleys of
Central and Northern PA

&&

.KEY MESSAGES...
1) One more day of comfortably cool/pleasant and rain-free
conditions today

2) Warm/humid conditions return mid to late week with best odds
for rain Thursday

&&

.DISCUSSION...
KEY MESSAGE 1: One more day of comfortably cool/pleasant and
rain-free conditions today

Clear skies, light/variable wind and very cool temps in the
upper 30s to upper 40s will lead a fairly extensive valley fog
as a result of air/water delta Ts easily exceeding 20 deg F.

The fog will dissipate between 12-1330Z as temps bump up a few
deg F and a light SE to southerly wind develops.

Otherwise, A ridge of high pressure stretched from the Upper
Saint Lawrence River Valley south into Pennsylvania this
morning. This weather feature will bring the region another
pleasant late Summer day with a mix of sunshine and mid and high
clouds, along with a light southeast to southerly breeze and
comfortably low humidity.

A wide 25-35 degree diurnal range is fcst for today with
afternoon high temps ranging from the upper 60s North to mid
and upper 70s in the Southern Valleys.


KEY MESSAGE 2: Warm/humid conditions return mid to late week
with best odds for rain Thursday

Fair and cool weather will continue for tonight, before humidity
and temperatures steadily climb Wednesday and peak on Thursday.

There will be a high probability of showers and scattered
thunderstorms late Wednesday into early Thursday across the
Northwest Mountains and mainly during the daylight hours Thursday
across Central PA and the Susquehanna Valley, as a weak front
sinks southward from the eastern Great Lakes.

If the front can push south of the MD line, most of Friday
could be dry. Precip odds then steadily increase for the second
half of the weekend, ahead of next frontal system progression
from the Great Lakes. Large scale upper level ridging should
support a mid to late week warming trend with the largest hi/lo
departure from climo Wed-Thu.

&&

sunrise. Main area of lower clouds and fog at IPT and SEG.

More information below.

Looking at mainly clear skies through 06Z Wed. Some mid and high
clouds later today and tonight, mainly across the northwest at

showers will be mainly north of the PA, NY border prior to
early afternoon on Wed. Support for showers and isolated
storms. More in the way of widespread showers will be possible
on Thursday,
