CAPE 500-1000, Lift Index 0 to -6 , Lapse rates 6.0-7.0..shear appears to be lacking in the northern areas in SW PA for example but around the vicinity of the low itself shear of 30-40 knots in place... The same upper level low that has been spinning its way from the south central states is now on the move to the north and the east. This low should slowly make its way east now and this low will once again be responsible for severe weather across the area along with heavy rains. Winds and hail (with the colder air aloft) should be the primary threats..However..can not rule out the chances of tornados..
