EVENT...FAVORABLE ENVIRONMENT FOR SLOW-MOVING TSTMS EXPECTED TO PERSIST
THIS AFTERNOON
.
SATELLITE ANALYSIS AND TRENDS...SCATTERED SHOWERS/TSTMS HAVE DEVELOPED
IN THE LAST COUPLE OF HRS ACROSS W VA/WV/SW PA AS A MID-LVL CIRCULATION
DEPICTED IN WV IMAGERY IS SEEN SPINNING OVER E WV.  MAX AREA OF UPPER-LVL
DIVERGENCE IS SEEN CENTERED ALONG THE OH/PA/WV BORDER IN GOES STLT
EXPERIMENTAL WINDS.  THIS MID-LVL CIRCULATION IS NOT EXPECTED TO EVACUATE
THE REGION UNTIL THIS EVENING AND WITH DAYTIME HEATING WARMING THE LOWER
LVLS SHOWERS/TSTMS ARE LIKELY TO PERSIST FOR THE NEXT SEVERAL HRS ACROSS
W VA/E AND N WV/SW PA/W MD.  PW VALUES ARE FOUND TO BE BETWEEN 1.3-1.5"
ACROSS THE DISCUSSION AREA.  BEST SFC MOISTURE CONVERGENCE AXIS IS
OBJECTIVELY ANALYZED TO BE RUNNING SW-NE ACROSS S WV TO S-CENTRAL PA.
SHOWERS/TSTMS WILL BE CAPABLE OF PRODUCING HVY RAINS AND WILL BE
SLOW-MOVING.  STORMS SHOULD DRIFT SLOWLY TO THE NE BASED ON LVL AND
MID-LVL FLOW.
