DISCUSSION:
A pair of disturbances moving northeastward from the Ohio Valley and along
the spine of the Appalachians will spark rounds of primarily afternoon and
evening showers and thunderstorms through Saturday. The main threats from
the storms will be frequent lightning, blinding downpours and flash
flooding of low-lying, urban- and poor-drainage areas, but locally damaging
wind gusts may also occur this afternoon. Ahead of each disturbance, southwesterly
flow will continue to pump hot and sultry air into the Lower Susquehanna Valley. High
temperatures will be near 90 degrees this afternoon and in the upper 80s
on Saturday with dewpoints in the low-to-mid 70s and peak heat indices of
95-100 degrees. If you have prolonged, outdoor plans, drink plenty of non-alcoholic beverages and take
breaks in the shade or an air-conditioned
room. Behind Saturday's disturbance, an area of high pressure will settle
into the central Appalachians and western PA on Sunday and promote mostly
sunny and drier conditions. Humidity should also be slightly lower, as
well, with dewpoints in the upper 60s.
