HYDROMETEOROLOGICAL DISCUSSION
MIDDLE ATLANTIC RIVER FORECAST CENTER
NATIONAL WEATHER SERVICE STATE COLLEGE PA
 810 AM EDT SAT AUG 30 2014

There was no precipitation across the Middle Atlantic River
Forecast Center (MARFC) hydrologic service area over the
past 24 hours.

High pressure will continue fair and dry weather today into
early Sunday.  There could be a passing shower or thunderstorm
across our far western river basins this afternoon or evening
but most of our forecast area will remain dry.

Dewpoints and PW`s will be on the increase and combine this
deep moisture with the arrival of a weak cold front will come
the likelihood of showers and thunderstorms Sunday.

72 hour basin average QPF is forecast to range from a tenth
/0.10/ to one half /0.50/ inch.  However, with PWAT`s rising to
1.50 to 3.00 inches expect locally heavy downpours in a short
period of time.  While main stem river response is expected to
be minor (2 feet or less) sharper rises will be possible on
smaller streams and creeks in the vicinity of heavy downpours
Sunday into Monday.

MARFC river and stream forecasts will be issued before 11am.
