AREAS AFFECTED...PARTS OF WESTERN AND CENTRAL PENNSYLVANIA
CONCERNING...TORNADO WATCH 336...
VALID 142154Z - 142330Z
THE SEVERE WEATHER THREAT FOR TORNADO WATCH 336 CONTINUES.
SUMMARY...SUPERCELL TORNADO RISK WILL PERSIST FOR ANOTHER FEW HOURS.
A COUPLE TORNADOES AND DAMAGING WINDS ARE ALSO POSSIBLE WITH THE
APPROACHING SQUALL LINE FROM THE WEST.
DISCUSSION...THE LATEST RADAR DATA FROM CCX SHOWS A FEW DISCRETE
SUPERCELLS EVOLVING ACROSS WESTERN AND CENTRAL PA AHEAD OF A COLD
FRONT AND RELATED SQUALL LINE. THE CCX VWP IS SAMPLING A 30-40 KT
LOW-LEVEL JET, WHICH IS YIELDING A CLOCKWISE-CURVED LOW-LEVEL
HODOGRAPH WITH AMPLE STREAMWISE VORTICITY FOR RM SUPERCELLS (320
M2/S2 0-1KM SRH). THIS WIND PROFILE COUPLED WITH A WARM/MOIST PBL
(MIDDLE/UPPER 60S DEWPOINTS) WILL CONTINUE TO SUPPORT A FEW DISCRETE
SUPERCELL STRUCTURES CAPABLE OF PRODUCING A COUPLE OF TORNADOES. THE
SUPERCELL TORNADO RISK WILL GENERALLY BE MAXIMIZED FOR THE NEXT FEW
HOURS (THROUGH AROUND 01Z), BEFORE THE CORE OF THE LOW-LEVEL JET
TRANSLATES NORTHWARD.
EMBEDDED TORNADOES AND DAMAGING WIND GUSTS WILL ALSO BE POSSIBLE
WITH THE NORTHEAST/SOUTHWEST-ORIENTED SQUALL LINE AS IT ADVANCES
EASTWARD ACROSS WESTERN/CENTRAL PA, GIVEN THE AFOREMENTIONED
FAVORABLE DOWNSTREAM ENVIRONMENT.
