AREAS AFFECTED...ERN MO THROUGH WRN AND SRN IL

CONCERNING...TORNADO WATCH 880...

VALID 280521Z - 280645Z

THREAT FOR PRIMARILY DAMAGING WIND AND AN ISOLATED TORNADO PERSIST
ACROSS ERN MO INTO WRN IL. THREAT IS EXPECTED TO SPREAD FARTHER EAST
INTO IL. ANOTHER WW WILL BE ISSUED SHORTLY.

A CLUSTER OF STORMS IS SPREADING THROUGH ERN MO INTO EXTREME WRN IL.
SOME ORGANIZED STRUCTURES INCLUDING BOW ECHOES AND EMBEDDED
SUPERCELLS CONTINUE WITHIN THIS AREA OF STORMS. THE LATEST RUC
SOUNDINGS SUGGEST THAT WITH OBSERVED SURFACE TEMPERATURES AND
DEWPOINTS IN THE 50S...MOST STORMS ARE LIKELY ELEVATED. WHILE THIS
DOES NOT PRECLUDE SEVERE CONVECTIVE GUSTS AT THE SURFACE OR AN
ISOLATED TORNADO...IT COULD SERVE AS A LIMITING FACTOR. A STRONG 70+
KT LOW LEVEL JET COUPLED WITH THE EXIT REGION OF A 100+ KT UPPER JET
WILL CONTINUE SPREADING NEWD THROUGH THE MID MS VALLEY. THE
ACCOMPANYING THETA-E ADVECTION SUGGESTS THE ATMOSPHERE WILL CONTINUE
TO DESTABILIZE NEWD WITH TIME. VERY STRONG LOW LEVEL AND DEEP LAYER
SHEAR PROFILES WILL CONTINUE TO SUPPORT THE POTENTIAL FOR ORGANIZED
STORM STRUCTURES.
