Severe weather marches east


There is a moderate risk of severe weather today from NE Texas to southern Illinois. A Public Severe Weather Outlook has been issued. The SPC says, in part,"

TORNADO POTENTIAL WOULD BE HIGHEST IF CELLS MANAGE TO DEVELOP IN
WARM SECTOR. OTHERWISE...LINE OF STORMS CURRENTLY MOVING INTO CNTRL
TX WILL LIKELY CONTINUE EAST INTO ERN OK AND NERN TX EARLY
THURSDAY...THEN INTO THE MS VALLEY LATER IN THE MORNING AND
AFTERNOON. ORGANIZED STORMS INCLUDING SUPERCELLS AND LEWP STRUCTURES
CAPABLE OF PRODUCING SWATHS OF DAMAGING WIND AND ISOLATED TORNADOES
WILL REMAIN POSSIBLE WITH THIS LINE. SEVERE THREAT WILL SPREAD EAST
INTO THE OH AND TN VALLEYS FROM LATE AFTERNOON INTO THE OVERNIGHT
WITH A CONTINUED THREAT FOR DAMAGING WIND AND TORNADOES.




On Friday the threat of severe weather moves to the east, from Louisiana through western Pennsylvania. The SPC says:

...TENNESSEE VALLEY/CENTRAL GULF COAST STATES...
AT LEAST SCATTERED THUNDERSTORMS WILL LIKELY BE ONGOING EARLY IN THE
DAY ACROSS THE MID SOUTH/CENTRAL GULF COAST STATES. WITH A MOIST AND
UNSTABLE AIRMASS /1000-2000 J/KG MLCAPE/ AHEAD OF THE EAST-SOUTHEAST
ADVANCING COLD FRONT...ADDITIONAL DEVELOPMENT/INTENSIFICATION SHOULD
OCCUR BY AFTERNOON ACROSS THE TENNESSEE VALLEY/CENTRAL GULF COAST
STATES. WIND PROFILES WILL SUPPORT WELL-ORGANIZED MULTICELL
STORMS/POSSIBLE SUPERCELLS. DAMAGING WINDS/SEVERE HAIL SHOULD BE THE
PRIMARY HAZARDS.
