MESOSCALE DISCUSSION 1796
NWS STORM PREDICTION CENTER NORMAN OK
0742 PM CDT THU SEP 10 2015

AREAS AFFECTED...PORTIONS OF NRN..CENTRAL AND ERN KS...SWRN MO

CONCERNING...SEVERE THUNDERSTORM WATCH 508...

VALID 110042Z - 110215Z

THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 508
CONTINUES.

SUMMARY...THE RISK FOR DAMAGING WINDS AND SEVERE HAIL CONTINUES
ACROSS REMAINING VALID PORTIONS OF THE WATCH AREA. A NEW WATCH MAY
BE NEEDED DOWNSTREAM ACROSS PORTIONS OF EASTERN AND SOUTHERN KANSAS
AND SOUTHWEST MISSOURI BY 01Z/8 PM CDT.

DISCUSSION...SEVERAL SEVERE THUNDERSTORMS EXHIBITING SUPERCELL
CHARACTERISTICS WERE IN PROGRESS AT 0030Z ALONG A COMPOSITE
EAST-WEST FRONTAL BOUNDARY OVER NORTHERN/CENTRAL KANSAS. A SMALL
CLUSTER OF SEVERE STORMS WAS ALSO LOCATED OVER EAST-CENTRAL KANSAS
IN THE VICINITY OF A NORTHWARD-MOVING OUTFLOW BOUNDARY. THE
LARGE-SCALE ENVIRONMENT REMAINS SUPPORTIVE OF A CONTINUED SEVERE
RISK...WITH MODERATE-STRONG SURFACE-BASED BUOYANCY AND AMPLE
DEEP-LAYER SHEAR FOR SUPERCELLS. LARGE-SCALE FORCING FOR ASCENT WITH
AN UPPER LEVEL IMPULSE OVER SOUTHERN NEBRASKA AND KANSAS WILL AID IN
ADDITIONAL STORM DEVELOPMENT...PRIMARILY ALONG CONSOLIDATING
OUTFLOWS GENERALLY ALONG I-70 FROM MANHATTAN TO NEAR TOPEKA. STORMS
WILL CONTINUE MOVING SOUTHEAST THROUGH THE REMAINDER OF THE EVENING
HOURS WITH A RISK FOR SEVERE WIND/HAIL. GIVEN FAVORABLE CONDITIONS
IN THE DOWNSTREAM ENVIRONMENT...A NEW WATCH WILL LIKELY BE NEEDED
OVER PORTIONS OF EASTERN KANSAS AND FAR SOUTHWEST MISSOURI BY 01Z.
