Area Forecast Discussion
National Weather Service State College PA
807 PM EDT MON JUL 25 2016

.SYNOPSIS...
A cold front will push southeast across Pennsylvania late today
and tonight. High pressure will return for mid week with
continued warm temperatures. Temperatures may trend back to near
or slightly below normal over the weekend.

&&

.NEAR TERM /UNTIL 6 AM TUESDAY MORNING/...
Severe Thunderstorm Watch down to southeast counties and will be
expiring at 8pm. Radar shows storms winding down with a decrease
in coverage and intensity.

HRRR timing suggests the showers/storms taper off and move south
fairly early this evening with improving skies in the wake of the
front. Areas that see rain ahead of the front and clearing skies
behind the front will have a good chance for some late night fog.

Low temps will vary from the l60s across the north...to the lower
70s across the SE zones.

&&

.SHORT TERM /6 AM TUESDAY MORNING THROUGH 6 PM TUESDAY/...
Tuesday looks very warm to hot but with much lower dewpoints as
compared to today. Highs will range from the low/mid 80s over the
NW to the low/mid 90s over the SE.

&&

.LONG TERM /TUESDAY NIGHT THROUGH MONDAY/...
In the extended the heat continues through midweek...then a
cooling trend to near normal highs looks likely for a few days as
several fronts linger over the area and the core of hot
temperatures shifts west.

The upper ridge across the Southern U.S. is forecast to
retrogress into the Southwestern U.S. by late in the week allowing
northern stream energy to produce a weak, but persistent troffing
across the northeast states.

Cold front currently crossing the region is forecast to stall just
south of the PA/MD border. A wave is forecast to form on the front
supported by the developing upper trof, moving east through the
Ohio Valley Friday and crossing PA on Saturday into Sunday. This
looks to bring a prolonged period of unsettled with weather with
showery conds across the state. The cloudiness will further
support cooler high temperatures than recent days. Low
temperatures during this period look to be several degrees above
normal, especially across southern sections of the state.

&&

.AVIATION /00Z TUESDAY THROUGH SATURDAY/...
A few more hours of showers and storms across the southern part
of the state. Storms formed earlier this afternoon with very high
dewpoints in the mid to upper 70s and temperatures in the 90s.

Anyway, most of the night should be dry with VFR conditions
early on. Some fog possible later.

Tuesday and Wednesday look to be dry with lower humidity
levels, and mainly VFR conditions.

OUTLOOK...

WED...VFR.

THU-SAT...Mainly VFR. SCT PM SHRA/TSRA.
