THE SEVERE WEATHER THREAT FOR TORNADO WATCH 5 CONTINUES.
SW OF WW 5...MONITORING FOR A POSSIBLE TORNADO WATCH ISSUANCE WITH
CONVECTION FORMING ALONG PRE-FRONTAL CONFLUENCE AXIS INTO NERN TX.
UNCERTAINTY EXISTS OVER THE POTENTIAL MATURITY OF SHOWERS THAT HAVE
FORMED SWWD ACROSS FAR NWRN LA INTO NACOGDOCHES COUNTY TX. THIS
DEVELOPMENT APPEARS TO BE ALONG THE TRAILING INFLUENCE OF THE SHORT
WAVE IMPULSE PIVOTING ACROSS MO/AR. AS THIS FEATURE PROGRESSES
NEWD...ASCENT ALONG THE PRE-FRONTAL CONFLUENCE AXIS SHOULD WANE.
STILL...MODERATE INSTABILITY JUXTAPOSED WITH RATHER STRONG
DEEP-LAYER SHEAR WOULD PROVE FAVORABLE FOR ALL MODES OF SEVERE
THREATS SHOULD CONVECTIVE DEVELOPMENT BE SUSTAINED. LATER THIS
EVENING...THE PACIFIC COLD FRONT WILL LIKELY OVERTAKE THIS
CONFLUENCE AXIS AND MAY REINVIGORATE DEVELOPMENT OVER PARTS OF NERN
LA INTO MS.
