Area forecast discussion, Jul 1, 5:41 PM EDT, 2 hours 5 minutes before

Area Forecast Discussion
National Weather Service State College PA
541 PM EDT Sat Jul 1 2017

.SYNOPSIS...
A cold front will move through the region late today bringing
break in the humidity for the second half of the weekend into
early next week. Summertime heat and humidity will return later
in the week.

&&

.NEAR TERM /UNTIL 6 AM SUNDAY MORNING/...

The main squall line has moved east of the forecast area as of
530. RAP shows some lingering CAPE over the region as the sun
broke out behind the line and allowed for some airmass
recovery.

There is a new line of storms moving toward NW Pa from Lake
Erie, and the HRRR marches this line into the Northern Mountains
between about 7 and 9PM. Severe storms do not seem likely, but
the still humid airmass could yet fuel additional downpours in a
few locations.

CAMs show the convection fading after sundown so most of the
region should stay dry for most of the overnight. With the
clearing skies, prior rain and very humid airmass, areas of fog
look like a good bet later tonight.

&&

.SHORT TERM /6 AM SUNDAY MORNING THROUGH 6 PM SUNDAY/...

Sunday looks cooler than normal in the NW. But, it should be
just a little warmer than normal in the SE thanks to a light
downslope and a good amount of sunshine there. Can't rule out
an aftn SHRA/TSRA in the north or the Laurels under the colder
air aloft.

&&

.LONG TERM /SUNDAY NIGHT THROUGH SATURDAY/...
The upper level trough will continue to move eastward Sunday
night into Monday. Latest models have a quasi stationary
boundary forming through Pennsylvania Monday into Tuesday. This
could allow for showers along this line, though PWATS are low so
lack of moisture is a concern for developing any showers.
However there is a weak cold frontal boundary and coupled with
daytime heating could allow for convection along this line
Monday afternoon into Tuesday. There is good agreement on the
position and movement of the trough which gives me some
confidence that Tuesday through Wednesday should be dry due to
SFC high pressure. The latter part of the work week should be
more active with another trough swinging through the Southern
Great lakes region and the OHIO valley. This could bring some
showers and thunderstorms late Wednesday through Thursday.
Temperatures will be around normal through the week with a drop
in temperatures towards next weekend as the trough brings cooler
northwesterly flow into the region.

&&

.AVIATION /22Z SATURDAY THROUGH THURSDAY/...
Band of heavy showers/storms have pushed east of central Pa
early this evening with widespread VFR conditions noted at 21Z.
Focus for the rest of the evening will be on another dying band
of showers/thunderstorms working into the region ahead of a cold
front over the Grt Lks. Linear extrapolation and HRRR support
a brief vis reduction at KBFD sometime between 23Z-01Z as these
storms move through. Further southeast, coverage will be more
sparse, as the showers/storms weaken after sunset. Still, can't
rule out a brief vis reduction at KIPT/KUNV/KJST late this
evening.

Main concern late tonight/early Sunday remains the possibility
for a period of low cigs developing along the spine of the
Appalachians between 09Z-13Z. Model soundings and SREF prob
charts support about a 50 pct chance of reductions at KBFD and
KJST. Otherwise, high pressure building over the region should
ensure widespread VFR conditions for the rest of Sunday.

.OUTLOOK...

Mon...Isold PM Tstorm impacts possible southern 1/2 airspace.

Tue...Isold PM Tstorm impacts possible southwest 1/3 airspace.

Wed...Isold PM Tstorm impacts possible.

Thu...Chance of showers and thunderstorms.

&&

.CTP WATCHES/WARNINGS/ADVISORIES...
None.
