Area Forecast Discussion

603 PM EDT WED JUL 6 2016

.SYNOPSIS...
Warm and humid conditions will continue the remainder of the week,
before a cold front brings cooler and less humid conditions Sunday.

&&

.NEAR TERM /THROUGH THURSDAY/...
Shortwave will continue to support a few showers and
thunderstorms across the region this evening. While there is
plenty of instability, there is little shear to support long
lasting, severe storms. That being said, cannot rule out a few
strong storms that tap into the dry air above the warm inversion
aloft, as steep level lapse rates are present near the surface to
help with wind acceleration.

The latest hi res model guidance does have precipitation making
it across Western Pa, so pops were adjusted based on a blend of
these models.

Another warm and humid day on tap for Thursday. With no lifting
mechanism present until late and strengthening warm air aloft, it
appears that thunderstorms will be suppressed across the region
on. Therefore, very low pops were maintained until later Thursday
night.

&&

.SHORT TERM /THURSDAY NIGHT THROUGH SATURDAY/...
The chance for showers and thunderstorms will continue through
Saturday as several impulses move across the upper Ohio Valley
ahead of a deeper upper trough progged to cross the Great Lakes.
Warm and humid conditions will continue until the cold front
crosses late Friday.

Friday looks like the best day for more widespread storms as a
cold front approaches, and surface instability and deep layer
shear increases. Overall model consensus is good, prompting SPC
to highlight much of region in a slight risk for severe
thunderstorms. Will continue mention of this in HWO. A secondary
cold front will bring scattered showers and usher in cooler and
less humid conditions Saturday and Sunday.

&&

.LONG TERM /SATURDAY NIGHT THROUGH WEDNESDAY/...
Upper trough will over New England will maintain seasonably cool
temperatures on Sunday before upper ridging take place. Dry
conditions and near normal temperatures are forecast through the
middle of next week.

&&

.AVIATION /21Z WEDNESDAY THROUGH MONDAY/...
General VFR can be expected for the TAF period although a crossing
shortwave may support some brief restrictions this evening with
some showers. Any fog will be limited to terminals which receive
measurable rain, with relatively low crossover temperature and
patchy mid level cloudiness providing inhibition elsewhere.

Warm mid level temperature is expected to continue suppressing
precip on Thursday with only isolated, to scattered convection
anticipated with an afternoon/evening upper disturbance
encroachment.

.OUTLOOK /THURSDAY NIGHT THROUGH MONDAY/...
The next chance for widespread restrictions is expected Thursday
and Friday with crossing disturbances.
