CONCERNING...SEVERE THUNDERSTORM WATCH 699...

VALID 122224Z - 122330Z

THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 699
CONTINUES.

AT 22Z...A BAND OF STORMS EXTENDED NEAR A CBM-JAN LINE AND WERE
MOVING EWD AT 20-25 KT. INSTABILITY IS NOT PARTICULARLY  STRONG
...AND OUTFLOWS ADVANCING EWD FROM STORMS WERE SLOWLY STABILIZING
THE BOUNDARY LAYER. DEEP LAYER SHEAR AT AROUND 30 KT AND THE
ORGANIZED STORMS OUTFLOW SHOULD CONTINUE TO SPREAD THE STORMS EWD
INTO THE EVENING HOURS.

OTHER ISOLATED STORMS WERE LOCATED IN SRN MS BETWEEN HEZ AND PIB AND
MAY REMAIN SEVERE A LITTLE LONGER THAN THOSE FURTHER NORTH DUE TO
WEAKER OUTFLOWS.

THE GREATEST SEVERE THREAT IS EXPECTED TO BE HAIL...THOUGH GIVEN THE
WEAK INSTABILITY...THE SEVERE STORMS ARE EXPECTED TO DIMINISH
RAPIDLY TOWARD 01Z AS THE BOUNDARY COOLS AND THE AIR MASS
STABILIZES.

THE THREAT OF SEVERE WEATHER WEST OF A UOX-HEZ LINE APPEARS MINIMAL
DUE TO THE RAIN COOLED BOUNDARY LAYER.
