MODERATELY STRONG DIRECTIONAL AND SPEED SHEAR IN THE 0-3KM LAYER CREATED A FAVORABLE ENVIRONMENT FOR SHALLOW TOPPED STORMS WITH DECENT UPDRAFTS AND GUSTY WINDS. SEVERAL MINI BOW ECHOES IN THE INITIAL TSRA LINE DURING THE LATE AFTERNOON PRODUCED ISOLATED DAMAGE ACROSS THE NW MTNS. THE TSRA THAT PRODUCED A TORNADO TOUCHDOWN NEAR ROCKTON IN NW CLEARFIELD COUNTY...MAINTAINED MODERATE TO STRONG ROTATION AT THE 0.5 AND 1.5 DEG ELEVATION SCANS FOR OVER AN HOUR! ROTATION DIMINISHED AS IT MOVED INTO NW CLINTON COUNTY AROUND 9 PM. 0-3 KM HELICITY CONTINUES TO INCREASE RAPIDLY TONIGHT BASED ON 18Z ETA BUFKIT HOURLY PROFILES AT KUNV. VALUES EXCEED 200 M2/S2 AFTER MIDNIGHT TONIGHT...BUT POTENTIAL FOR TORNADOES WILL DECREASE BASED ON LESSER UPDRAFT STRENGTH AND SIGNIFICANTLY LOWER CAPE. PREVIOUS FORECAST WORDING FOR LIKELY TO CATEGORICAL POPS OVER THE WEST...AND LIKELY POPS LATE TONIGHT IN THE EAST LOOKS FINE BASED ON RADAR COVERAGE ATTM. COLD FRONT MOVES ACROSS CENTRAL PENN AROUND 12Z FRIDAY. CHC FOR SHRA AND TSRA WILL REMAIN UNTIL EARLY AFTERNOON ACROSS THE CENTRAL SUSQ VALLEY REGION.
