severe weather possible south central texas

Statement as of 2:05 PM CDT on Abril 16, 2009 ... Wet weather and possible severe weather on the way for south central Texas late tonight through Saturday... An approaching upper level low pressure area and cold front over the weekend will bring much needed rain to south central Texas over the next couple days. The low pressure system was moving through the southern rockies and will slowly descend on Texas starting tonight. Showers and a few thunderstorms will develop in the moist flow across south Texas this afternoon and then increase from west to east later this evening and overnight. Rainfall will continue in a series of waves through Saturday evening. Rain totals will be greatest in eastern sections of our area with up to two inches possible. Out west look for average rainfall amounts near one half inch. In addition to the rain there is a chance for severe thunderstorms. The mostly likely time for severe storms will be on Friday. The greatest threat will be for large hail... with strong winds also possible... and the most likely location will be the eastern half of the forecast area.

ERN NM INTO TX/OK...        WHILE MARITIME TROPICAL AIR WILL REMAIN CONFINED TO DEEP S TX AND    THE NWRN GULF OF MEXICO /S OF COASTAL FRONT/...LOW-LEVEL MASS    RESPONSE TO APPROACHING MID-LEVEL LOW WILL SERVE TO ENHANCE THE NWWD    ADVECTION OF AN INCREASINGLY MOIST BOUNDARY LAYER THROUGH THE    EDWARDS PLATEAU INTO WRN TX.  THIS PROCESS WILL OCCUR BENEATH    EML/STEEP LAPSE RATE PLUME SPREADING EWD ACROSS THE SRN HIGH    PLAINS...SUPPORTING DECREASING STATIC STABILITY SATURDAY AFTERNOON    INTO SATURDAY NIGHT.        BECAUSE OF THE INITIALLY LIMITED BOUNDARY LAYER MOISTURE...LATEST    MODEL GUIDANCE SUGGESTS THAT EML/CAPPING WILL LIMIT THE AREAL    COVERAGE OF ANY DIURNAL STORMS TO A NARROW CORRIDOR ALONG DRYLINE    WHERE LOCALLY STRONGER DIABATIC HEATING WILL BE SUFFICIENT TO    OVERCOME CONVECTIVE INHIBITION.  THE COMBINATION OF INCREASED    FORCING FOR ASCENT AND THE ARRIVAL OF RICHER MOISTURE ALONG    NOCTURNAL LLJ AXIS SHOULD PROMOTE AN INCREASE IN STORM COVERAGE    SATURDAY NIGHT ACROSS PARTS OF WRN INTO NRN/CNTRL TX AND SRN OK.     THIS ACTIVITY WILL LIKELY REMAIN ELEVATED ABOVE A STABLE BOUNDARY    LAYER AND ROOTED WITHIN STEEP LAPSE RATE ENVIRONMENT WHERE MUCAPE    WILL APPROACH 1000-1500 J/KG.          GIVEN EFFECTIVE BULK SHEAR OF 40-45 KT...POTENTIAL WILL EXIST FOR    SUPERCELLS...BOTH WITH THE DIURNAL SURFACE-BASED DEVELOPMENT OVER    SERN NM/WRN TX...AS WELL AS WITHIN THE ELEVATED REGIME SATURDAY    NIGHT.  WHILE HAIL WILL BE THE PRIMARY SEVERE THREAT...LOCALLY    STRONG WIND GUSTS WILL BE POSSIBLE WITH ANY SURFACE-BASED STORMS.
