CONVERGENCE ALONG THE BOUNDARY. IN ADDITION...THE RUC ANALYSIS IS
SHOWING A SHORTWAVE TROUGH ENTERING WEST TX AND THIS MAY BE
INCREASING ASCENT OVER A LARGE AREA. AS A RESULT...STORM COVERAGE
MAY CONTINUE TO INCREASE OVER THE NEXT FEW HOURS AS A LARGE MCS
ORGANIZES ACROSS WEST TX. THE SLOW MOVEMENT OF THE CONVECTION WILL
RESULT IN VERY HEAVY RAIN. IN ADDITION...MLCAPE VALUES OF 1000 TO
1500 J/KG AND 0-6 KM SHEAR VALUES AROUND 30 KT WILL BE SUFFICIENT
FOR SEVERE MULTICELL STORMS WITH THE POSSIBILITY OF HAIL AND
