REMNANT MCV APPEARS TO BE CENTERED OVER CENTRAL LA ATTM...AND IS AIDING UPDRAFTS ACROSS THE TOLEDO BEND COUNTRY...EWD INTO CENTRAL LA. LATEST LAPS CAPE IS SHOWING VERY UNSTABLE AIR ACROSS THE ENTIRE REGION...WITH THE HIGHEST AREAS ACROSS NW LA...DEEP E TX...AND SE OK...AND CU FIELD LOOKING HEALTHIER WITH EACH VIS SATELLITE IMAGE UPDATE. NO REASON TO BELIEVE THAT WE WON'T HAVE AT LEAST SOME ISOLD/WIDELY SCT STORMS DEVELOP ACROSS E TX AND SW AR AS WE MOVE THROUGH THE REST OF THE DAYLIGHT HOURS. LOTS OF UNCERTAINTY IN THE DAYS AHEAD...AS THE MODELS CONTINUE TO MEANDER THE MCV/UPPER LOW SEWD AND THEN BACK TOWARD THE W THROUGH THE WEEKEND. IN THE MEAN TIME...MODELS AMPLIFY THE UPPER RIDGE OVER THE OH RIVER VALLEY KEEPING THE REGION UNDER WEAK FLOW ALOFT. SFC LOW TO OUR W AND RIDGE TO THE E WILL KEEP A STEADY SUPPLY OF LL MOISTURE COMING IN. THIS COMBINED WITH HEATING AND WEAKNESSES IN THE RIDGE WILL WARRANT AT LEAST SLIGHT CHANCE POPS IN THROUGHOUT MOST OF THE FCST PD. ANY MESOSCALE FEATURES SUCH AS OUTFLOW BOUNDARIES WILL ENHANCE THIS POSSIBILITY. TEMPS LOOK TO HOLD NEAR NORMAL THIS PD FOR THE MOST PART...AS DAILY CLOUDS/CONVECTION KEEP US FROM HEATING UP TOO MUCH. /12/ && .AVIATION...
