AREAS AFFECTED...ERN MO...IL...SERN IA
CONCERNING...SEVERE POTENTIAL...WATCH LIKELY
VALID 301629Z - 301730Z
PROBABILITY OF WATCH ISSUANCE...95 PERCENT
SUMMARY...SCATTERED TSTMS FORMING ACROSS SERN MO WILL LIKELY
COALESCE INTO N/NEWD MOVING ORGANIZED CLUSTERS/LINE SEGMENTS THIS
AFTERNOON. PRIMARY RISK SHOULD BE DAMAGING WINDS...BUT ISOLATED
SEVERE HAIL AND A TORNADO OR TWO IS ALSO POSSIBLE. WW WILL BE
COORDINATED SHORTLY.
DISCUSSION...AS AIR MASS DESTABILIZES DOWNSTREAM OF THE
AFOREMENTIONED CONVECTIVE DEVELOPMENT...SEVERE THREAT WILL
CORRESPONDINGLY INCREASE THIS AFTERNOON. VEER-BACK-VEER WIND
PROFILES AND THE LACK OF STRONGER DEEP-LAYER SHEAR SHOULD FOSTER
CONVECTION FORMING INTO CLUSTERS/SHORT-LINE SEGMENTS.
STILL...MODERATE LOW-LEVEL SHEAR COULD SUPPORT A COUPLE OF EMBEDDED
SUPERCELLS.
