CENTRAL PENNSYLVANIA FORECAST DISCUSSION NATIONAL WEATHER SERVICE STATE COLLEGE PA 830 AM EST SAT JAN 27 1996 SUGGESTIONS: PIT...CUD PROB DROP FLOOD WATCH WEST. MAIN ACTION SEEMS TO BE FUNNELING OVER ERN ZONES. ASIDE FROM GUSTY HEAVY DOWNPOUR AND POSSIBLE TRW WITH FRONT...DON'T THINK QPF'S WILL BE AS HIGH AS OVER EAST. DISCUSSION: STRONG COLD FRONT JUST THROUGH PIT WITH CLASSIC WSHFT TEMP DROP PRESRR. QPF'S SEEM TO BE WORKING OUT FOR THE MOST PART WITH EASTERN AREAS PROBABLY GOING TO RING UP IN THE 1.5 TO 2.5" RANGE. RIVER FORECASTS SHOW MANY POINTS TO GO OVER FLOOD USING QPF'S FROM OVERNIGHT. MAY BE JUST A BIT MORE RAIN THAN EARLIER QPF IN THOSE AREAS WHICH WILL NOT HELP THE WET PEOPLE MUCH.
