AREAS AFFECTED...I-70 CORRIDOR FROM NORTHERN KANSAS INTO NORTHWEST
MISSOURI
CONCERNING...SEVERE THUNDERSTORM WATCH 154...
VALID 270639Z - 270815Z
THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 154
CONTINUES.
SUMMARY...ELEVATED SUPERCELLS WILL CONTINUE TO POSE A LARGE HAIL AND
ISOLATED DAMAGING WIND THREAT WHILE SPREADING EASTWARD ALONG THE
I-70 CORRIDOR.
DISCUSSION...CLUSTERS OF ELEVATED SUPERCELLS, WITH A RECENT HISTORY
OF HAIL UP TO 2 INCHES IN DIAMETER, CONTINUE TO SPREAD EASTWARD
ALONG THE I-70 CORRIDOR IN NORTH CENTRAL AND NORTHEAST KS. THIS
AREA IS WITHIN THE LEFT-EXIT REGION OF A 100 KT JET AT 300 MB, AND
ALONG THE NORTH EDGE OF THE STEEP MIDLEVEL LAPSE RATES WHERE STRONG
LOW-LEVEL WARM ADVECTION IS ONGOING. THE UPDRAFTS APPEAR TO BE
ROOTED NEAR 850 MB WITH MUCAPE NEAR 3000 J/KG. THE COMBINATION OF
LARGE BUOYANCY AND STRONG CLOUD-LAYER/EFFECTIVE SHEAR WILL CONTINUE
TO FAVOR SUPERCELLS CAPABLE OF PRODUCING VERY LARGE HAIL (NEAR OR
ABOVE 2 INCHES IN DIAMETER). THESE STORMS WILL ALSO BE CAPABLE OF
PRODUCING ISOLATED WIND DAMAGE GIVEN THE STEEP MIDLEVEL LAPSE RATES
AND MODERATELY LARGE DCAPE.
