SPREADING EWD/SWD WITH CONVECTIVE BACKBUILDING TAKING PLACE UPSTREAM
ACROSS THE LOW ROLLING PLAINS. MODEST INCREASES IN MLCINH E OF THE

OF THE DFW METROPLEX AND VICINITY. LARGE-SCALE ASCENT AHEAD OF A
MID-LEVEL TROUGH WILL SUPPORT CONVECTIVE BACKBUILDING INTO THE
OVERNIGHT HOURS ACROSS PARTS OF NW TX. WW 170 IS PRESENTLY SCHEDULED
TO EXPIRE AT 04Z. HOWEVER...SOME SVR RISK MAY CONTINUE LATER INTO
THE OVERNIGHT HOURS AS MODERATELY TO STRONGLY UNSTABLE INFLOW EXISTS
