CONCERNING...TORNADO WATCH 234...235...
VALID 070110Z - 070315Z
THE SEVERE WEATHER THREAT FOR TORNADO WATCH 234, 235 CONTINUES.
SUMMARY...STRONG CONVECTION, EMBEDDED WITHIN A BROADER AREA OF
THUNDERSTORM ACTIVITY, COULD STILL GRADUALLY ORGANIZE THIS EVENING
ACROSS PARTS OF CENTRAL LOUISIANA INTO SOUTHWESTERN AND SOUTH
CENTRAL LOUISIANA. ALTHOUGH UNCERTAIN, IT IS POSSIBLE TORNADO WATCH
234 WILL BE ALLOWED TO EXPIRE AS SCHEDULED AT 02Z.
DISCUSSION...ALTHOUGH THE PRIMARY SURFACE BAROCLINIC ZONE REMAINS
STALLED ACROSS CENTRAL LOUISIANA THROUGH SOUTHERN MISSISSIPPI,
CONSOLIDATING CONVECTIVE DEVELOPMENT ACROSS MUCH OF SOUTHERN INTO
CENTRAL LOUISIANA AND SOUTHWESTERN MISSISSIPPI HAS PRIMARILY REMAIN
ROOTED WITHIN LIFT ASSOCIATED WITH WARM ADVECTION, ABOVE THE
SEASONABLY MOIST BOUNDARY LAYER. THIS IDEA IS SUPPORTED BY 07/00Z
RAOBS FROM LAKE CHARLES AND SLIDELL.
IF LIFT OF BOUNDARY-LAYER PARCELS THROUGH AT LEAST WEAK INHIBITION
EVIDENT IN THE 850-700 MB LAYER COULD BE SUSTAINED, THE ENVIRONMENT
STILL APPEARS SUPPORTIVE OF SUPERCELLS WITH THE CONDITIONAL RISK OF
A STRONG TORNADO. HOWEVER, THIS IS APPEARING LESS LIKELY WITH TIME.
IT STILL MIGHT NOT BE OUT OF THE QUESTION THAT STRONGER CONVECTION
COULD GRADUALLY ORGANIZE OVER THE NEXT FEW HOURS, PARTICULARLY CLOSE
TO THE FRONTAL ZONE ACROSS SOUTHWESTERN/SOUTH CENTRAL MISSISSIPPI.
THIS COULD RESULT IN ANOTHER DEVELOPING MESOSCALE CONVECTIVE VORTEX,
PERHAPS ACCOMPANIED BY INCREASING POTENTIAL FOR STRONG TO SEVERE
SURFACE GUSTS.
