THE SEVERE WEATHER THREAT FOR TORNADO WATCH 757...758...CONTINUES.

A BAND OF STRONG TO SEVERE THUNDERSTORMS CONTINUES TO AFFECT
PORTIONS OF CENTRAL/EASTERN AL AND NORTHWEST GA THIS MORNING.  THE
STRONGEST STORMS HAVE BEEN NOTED ALONG A LINE FROM WEST OF
MONTGOMERY TO NEAR ANNISTON AL...WHERE MULTIPLE MESOCYCLONES HAVE
BEEN OBSERVED ON RADAR.  RECENT VAD PROFILES AND FORECAST SOUNDINGS
SHOW 3KM HELICITY VALUES OF 300-400 M2/S2 AND VERY STRONG DEEP LAYER
VERTICAL SHEAR AHEAD OF THE STORMS.  THESE CONDITIONS WILL CONTINUE
TO PROMOTE OCCASIONAL SUPERCELL STRUCTURES AND THE RISK OF DAMAGING
WINDS/TORNADOES THROUGH THE EARLY AFTERNOON ACROSS EASTERN AL AND
FAR WESTERN GA.  THE NORTHEASTWARD EXTENT OF THE SEVERE THREAT WILL
BE LIMITED BY WEDGE FRONT IN PLACE OVER NORTHERN GA...WITH A
COOLER/DRIER AND MORE STABLE AIR MASS IN THAT AREA.
