This Hazardous Weather Outlook is for central Pennsylvania.
.DAY ONE...Today and tonight.
A few strong thunderstorms containing small hail and gusty
winds will likely form across the Northern Mountains of the
state this afternoon and drift slowly south across the Central
Mountains, Middle Susquehanna Valley and Western Poconos
late today and this evening.
.DAYS TWO THROUGH SEVEN...Friday through Wednesday.
Several rounds of slow-moving showers and thunderstorms
with locally heavy rainfall will occur Friday night through
Sunday and could result in an increasing threat for flash
flooding of small streams, creeks and poor drainage areas.
The greatest risk for flash flooding will likely be late
Saturday and Sunday. The southern portion of the state and
areas of complex terrain will be especially vulnerable given
enhanced rapid runoff with heavy rainfall.
