Area forecast discussion, Mar 22, 8:20 PM CST, 5 hours before
AREA FORECAST DISCUSSION...UPDATED NATIONAL WEATHER SERVICE LUBBOCK TX 820 PM CST WED MAR 22 2000 LINEAR MESOSCALE CONVECTIVE SYSTEM (MCS) HAS DEVELOPED ACROSS THE EASTERN ZONES. SEVERAL SEVERE THUNDERSTORMS ARE EMBEDDED IN THE LINE OF DEEP CONVECTION ALONG THE LEADING EDGE OF THE MCS. DEEP CONVECTION CONTINUES TO PROPAGATE EAST INTO ENVIRONMENT CHARACTERIZED BY INFLOW OF HIGH LOW-LEVEL THETAE AND STRONG VERTICAL WIND SHEAR. MAIN SEVERE WEATHER THREAT THUS LOOKS TO BE EAST OF OUR AREA AT THIS TIME. IN ITS WAKE, PERSISTENT LIGHT TO MODERATE RAIN WAS NOTED, GENERALLY EAST OF I-27. FLASH FLOOD WATCH STILL OK, ALTHOUGH AT THIS POINT THE WESTERN PART OF THE WATCH IS TO COVER POTENTIAL FOR LATE NIGHT ACTIVITY. MEANWHILE, UPPER LOW LOOKS TO HAVE REFORMED A LITTLE EAST INTO SOUTHWEST NEW MEXICO. THIS IS IN LINE WITH EARLIER PROGS, AS WELL AS 18Z MESOETA AND LATEST RUC WHICH BEGINS TO PULL SYSTEM NORTHEAST OVERNIGHT. RUC MOVES STRONG SURFACE LOW TO THE NORTH, LEADING TO STRONG BOUNDARY LAYER WARM ADVECTION, ESSENTIALLY REORIENTING THE LOW LEVEL BAROCLINIC ZONE FROM NORTHEAST-SOUTHWEST, TO NORTH-SOUTH ALONG OUR WESTERN ZONES. DESPITE THE CURRENT LULL IN ACTIVITY WEST OF THE MCS, SOME REDEVELOPMENT IS POSSIBLE OVERNIGHT (MAYBE SEVERE AS STEEP LAPSE MOVES EAST) ACROSS WESTERN HALF OF THE AREA AS THE UPPER SYSTEM MOVES NORTHEAST. HOWEVER, THE EXISTING MCS MAKES CONFIDENCE IN PROGGED EVOLUTION OF SURFACE FEATURES UNCERTAIN AT BEST. WILL LOWER POPS A LITTLE ACROSS WESTERN ZONES, OTHERWISE NO LARGE SCALE CHANGES EXPECTED FOR NOW. .LBB...FLASH FLOOD WATCH TONIGHT ZONES 23>26-29>32-35>38-41>44
