VALID 100100Z - 101200Z
...THERE IS A SLGT RISK OF SVR TSTMS OVER A PORTION OF COASTAL LA...
...SERN LA...
LINE OF STORMS PERSISTS ALONG WARM CONVEYOR BELT FROM NCNTRL INTO
SWRN LA AND THE NWRN GULF. THIS ACTIVITY IS EXPECTED TO CONTINUE
EWD...BUT TREND HAS BEEN FOR THE LINE TO DECELERATE. AT THE SFC A
QUASISTATIONARY FRONT EXTENDS FROM JUST INLAND OF THE COAST ACROSS
SERN LA...WWD TO WHERE IT INTERSECTS THE CONVECTIVE LINE IN SWRN LA.
WINDS ARE BACKED TO ELY NEAR AND NORTH OF THE FRONT RESULTING IN
LARGE HODOGRAPHS...ESPECIALLY ACROSS SCNTRL AND SWRN LA IN CLOSER
PROXIMITY TO THE LLJ. INSTABILITY REMAINS WEAK WITH MLCAPE AOB 500
J/KG MAINLY CONFINED TO THE LA COAST. RADAR DATA SHOW A FEW EMBEDDED
QLCS MESO-VORTICES MOVING ONTO THE SWRN LA COAST...AND THIS ACTIVITY
MAY POSE AT LEAST A MODEST THREAT FOR A TORNADO OR TWO AS IT MOVES
INLAND AND INTERACTS WITH QUASISTATIONARY FRONT THIS EVENING. HAVE
INCLUDED A SMALL SLIGHT RISK TO ACCOUNT FOR THIS SCENARIO.
OTHERWISE...TENDENCY WILL BE FOR THE LLJ TO GRADUALLY SHIFT NORTH OF
THE MARGINALLY UNSTABLE WARM SECTOR LATER TONIGHT AS THE UPPER LOW
LIFTS NWD THROUGH TX. REF SWOMCD 04 FOR MORE INFORMATION.
