NARROW BAND OF STORMS WITH HEAVY RAIN WILL SPREAD E/ESEWD FROM NERN
MS ACROSS NORTH CENTRAL AL THROUGH MID/LATE MORNING. IN
ADDITION...AN ISOLATED SEVERE HAIL/DAMAGING WIND THREAT IS POSSIBLE
THE NEXT COUPLE OF HOURS FROM AROUND BHM TO ANB.
COMBINATION OF VERY MOIST WEST-SOUTHWESTERLY FLOW IMPINGING ALONG
CONVECTIVE OUTFLOW BOUNDARY HAS RESULTED IN REGENERATION OF
CONVECTION FROM WEST OF CBM TO WEST BHM. THE LEADING STORM IN THIS
BAND...IN WALKER AND APPROACHING JEFFERSON COUNTY AL...HAS A WELL
DEFINED MID LEVEL CIRCULATION AND IS LAYING DOWN A BOUNDARY FOR
CONVECTION TO REGENERATE BEHIND IT. DESPITE STABLE BOUNDARY
LAYER...LEADING STORM IS MOVING ESEWD AT 25-30 KT AND CERTAINLY HAS
A LOCALIZED POTENTIAL FOR HAIL AND MARGINALLY SEVERE WINDS.

THUNDERSTORMS ACROSS THE SAME GENERAL AREAS. THE AIR MASS IS QUITE
MOIST...PW VALUES NEAR 1.75 INCHES...AND STRONG THETA ADVECTION
BETWEEN 900-700 MB SHOULD MAINTAIN STORMS WITH HEAVY RAINFALL
