Text of a new discussion from SPC. Alabama still under High Risk
——————————————————-
AREAS AFFECTED…ERN AR ACROSS NRN MS…WRN/MIDDLE TN…NRN AL
CONCERNING…SEVERE POTENTIAL…TORNADO WATCH LIKELY
VALID 011254Z – 011400Z
WIDESPREAD SEVERE WEATHER POTENTIAL TO INCLUDE POSSIBLE LONG-TRACK
TORNADOES WILL INCREASE ACROSS THE MS AND TN VALLEYS THROUGH THIS
MORNING. TORNADO WATCH COORDINATION ACROSS THESE AREAS WILL COMMENCE
SHORTLY.
POWERFUL LARGE SCALE MID/UPPER TROUGH CONTINUES TO MOVE EAST ACROSS
THE PLAINS THIS MORNING WITH PRONOUNCED DIFFLUENT FLOW OF OVER 100KT
FORECAST TO SPREAD EAST ATOP INCREASINGLY MOIST AND UNSTABLE WARM
SECTOR FROM THE NRN GULF COAST NWD ACROSS MS/AL…AND MUCH OF TN.
GIVEN SPEED OF THE UPPER SYSTEM AND WIDESPREAD NATURE OF THE
INTENSIFYING VERTICAL MOTION…A LARGE PDS WATCH MAY BE NEEDED.
STRENGTH OF LOW LEVEL SHEAR AND LOW LFC WILL SUPPORT THE POTENTIAL
FOR FAMILIES OF LONG-TRACK SUPERCELL STORMS. TORNADO
THREAT…CURRENTLY WELL ESTABLISHED OVER SRN MO…AR…AND LA…WILL
SHIFT STEADILY EWD ACROSS THE MS RIVER THROUGH THE MORNING.
