DISCUSSION...A BOWING CLUSTER, WITH A HISTORY OF MEASURE OUTFLOW
GUSTS UP TO 77-82 MPH, IS WELL ORGANIZED AND WILL LIKELY POSE A
CONTINUED SEVERE THREAT FOR ANOTHER FEW HOURS. THE CLUSTER IS
MOVING ALONG THE CORRIDOR OF MAXIMUM BUOYANCY, AND WILL BE FED BY A
30-40 KT LOW-LEVEL JET. THESE FACTORS MAY OFFSET THE GRADUAL
INCREASE IN CONVECTIVE INHIBITION AND ALLOW THE STORM CLUSTER TO
PERSIST NEAR THE MO RIVER THROUGH ABOUT 06Z. THEREAFTER, THE
STRENGTHENING CAP SHOULD RESULT IN GRADUAL WEAKENING OF THE STORMS.
