SATELLITE ANALYSIS AND TRENDS...LINE OF STRONG TSTORMS MAKING ITS WAY
THROUGH E OH AT THIS TIME IS SEEN DROPPING SEWD IN LAST FEW SAT IMAGES
TWDS SE OH/N WV. NEW CELLS HAVE INITIATED S OF I-70 IN SE OH IN AN AREA
THAT HAS BECOME VERY UNSTABLE PER GOES SOUNDER LI VALUES OF -6 TO -7 PER
DAYTIME HEATING. THIS UNSTABLE AREA STRETCHES E INTO EXTREME SW PA AND SE
INTO N/CENTRAL WV ALONG THE PRIMARY THETA-E AXIS. SWRLY SFC WINDS PUMPING
WARM FAIRLY MOIST AIR OF PW 1.8 TO NEAR 2" UP INTO A WAVE ALONG THE FRNT
HAS SET UP THE INGREDIENTS FOR HVY RAINS THIS AFTERNOON/EVENING. EXPECT
THE HEAVIEST RAINS SHOULD FALL OVER S/SE OH AND N/NW WV BUT SOME HVY
RAINS SHOULD FOLLOW INTO SW PA AS WELL ALONG THE SAME PATH THAT THE
VERY WARM TOP CELLS CURRENTLY OVER S PA HAVE TAKEN. TRAINING CELLS WILL
AGGRAVATE ALREADY SATURATED SOILS IN OH/SW PA/N WV AND COULD PRODUCE 2-3"
OVER THE AREA WITH LOCALLY HIGHER AMOUNTS PARTICULARLY OVER THE HIGHER
TERRAIN OF N WV/SW PA AND EXTREME WRN MD.
