AREAS AFFECTED...PARTS OF NORTHERN IN INTO WESTERN OH
CONCERNING...SEVERE THUNDERSTORM WATCH 560...
VALID 110100Z - 110230Z
THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 560
CONTINUES.
SUMMARY...A SEVERE HAIL/WIND THREAT WILL EXPAND EAST-SOUTHEASTWARD
ACROSS NORTHERN INDIANA INTO WESTERN OHIO THIS EVENING.
DISCUSSION...THUNDERSTORMS HAVE INCREASED IN COVERAGE THIS EVENING
ACROSS NORTHERN IN, LIKELY AIDED BY A WEAK MID-LEVEL DISTURBANCE
NOTED ON WATER VAPOR SATELLITE IMAGERY UPSTREAM ACROSS IL. INITIAL
CELLS HAVE UNDERGONE MERGERS, WITH MULTIPLE CLUSTERS ONGOING. AMPLE
LOW-LEVEL MOISTURE AND RELATED VERY STRONG BUOYANCY WILL CONTINUE TO
SUPPORT VIGOROUS UPDRAFTS, EVEN THOUGH STRONGER MID-LEVEL FLOW AND
RELATED DEEP-LAYER SHEAR WILL TEND TO REMAIN A BIT DISPLACED TO THE
NORTH OF THE SURFACE WARM SECTOR. EVEN SO, ENOUGH SHEAR SHOULD BE
PRESENT TO SUPPORT A MIX OF SUPERCELLS AND MULTICELLS IN THE SHORT
TERM (REFERENCE RECENT VWPS FROM KIWX). SEVERE HAIL GENERALLY UP TO
1-1.5 INCHES IN DIAMETER WILL BE POSSIBLE WITH ANY CELLS THAT CAN
REMAIN AT LEAST SEMI-DISCRETE, WHILE DAMAGING WINDS MAY OCCUR WITH
ANY SMALL CLUSTERS MOVING EAST-SOUTHEASTWARD. AN INCREASE IN THE
SEVERE WIND POTENTIAL MAY DEVELOP ACROSS PARTS OF NORTHEAST IN INTO
NORTHWEST OH IF A MORE DOMINANT CLUSTER CAN BECOME ESTABLISHED, AS
SOME SHORT-TERM GUIDANCE SUGGESTS.
