AREAS AFFECTED...SOUTHEAST TX...CENTRAL LA
CONCERNING...TORNADO WATCH 711...
VALID 190009Z - 190145Z
THE SEVERE WEATHER THREAT FOR TORNADO WATCH 711 CONTINUES.
SUMMARY...SCATTERED SUPERCELLS WILL CONTINUE SPREADING NORTHEAST
ACROSS THE EASTERN HALF OF WW711.
DISCUSSION...SEVERAL LONG-LIVED SUPERCELLS ARE NOTED WITHIN WW711
EARLY THIS EVENING. ONE IN PARTICULAR IS CROSSING NEWTON COUNTY TX
INTO NORTHWESTERN VERNON PARISH. THIS ACTIVITY APPEARS PARTLY AIDED
BY THE RIGHT-ENTRANCE REGION OF THE MID-LEVEL JET, ALONG WITH
SUSTAINED LOW-LEVEL WARM ADVECTION. WHILE LAPSE RATES ARE NOT THAT
STEEP, LOW-MID 70S SURFACE DEW POINTS ARE CONTRIBUTING TO
SIGNIFICANT BUOYANCY. UNTIL THE LLJ LIFTS NORTH OF THIS AIR MASS,
ORGANIZED SUPERCELL THREAT WILL LIKELY CONTINUE. PRIMARY RISK
CONTINUES TO BE DAMAGING WINDS ALONG WITH SOME TORNADO RISK,
ESPECIALLY FOR THE NEXT FEW HOURS.
