CONCERNING...SEVERE THUNDERSTORM WATCH 205...

VALID 250139Z - 250315Z

THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 205
CONTINUES.

SUMMARY...SEVERE-WEATHER THREAT SHOULD GRADUALLY DIMINISH THROUGH
THE EVENING WITH A FEW ADDITIONAL REPORTS OF LARGE HAIL AND/OR
DAMAGING WINDS STILL POSSIBLE ACROSS EAST-CENTRAL OK THROUGH 03Z.

DISCUSSION...AT 0125Z...MOSAIC RADAR IMAGERY SHOWED A SMALL CLUSTER
OF STORMS TRACKING TO THE EAST-SOUTHEAST ACROSS EAST-CENTRAL OK
WITHIN EASTERN MUSKOGEE AND WESTERN CHEROKEE COUNTIES...WITH 5-9-KM
MRMS CAPPI DATA MAINTAINING STRONG REFLECTIVITIES WITH THESE STORMS.
THESE STORMS WERE LOCATED NEAR AND MAINLY NORTH OF A CONVECTIVE
OUTFLOW BOUNDARY THAT EXTENDED FROM CENTRAL AR WEST-NORTHWESTWARD TO
SEBASTIAN COUNTY AR AND THEN WESTWARD THROUGH HASKELL TO LINCOLN
COUNTIES OK.

VWP DATA SHOWED A 25-35-KT SOUTH/SOUTHWESTERLY LLJ EXTENDING INTO
THE EAST-CENTRAL CLUSTER OF STORMS...PROVIDING A FEED OF MODERATE
INSTABILITY.  THIS COMBINED WITH EFFECTIVE BULK SHEAR OF 30-35 KT
SUGGESTS STORM ORGANIZATION WILL BE MAINTAINED FOR A FEW MORE HOURS.
GIVEN AN INCREASE IN SURFACE-BASED INHIBITION WITH THE LOSS OF
DAYTIME HEATING...THE THREAT FOR STRONG WIND GUSTS SHOULD DIMINISH
WITH EASTWARD EXTENT INTO WESTERN AR.  HAIL AROUND 1 INCH IN
DIAMETER WILL REMAIN POSSIBLE...GIVEN THE PRESENCE OF STEEP MIDLEVEL
LAPSE RATES /PER 00Z OUN SOUNDING/.
