Area forecast discussion, Jun 20, 8:30 PM MDT, 15 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MIDLAND TX 930 PM CDT SUN JUN 20 1999 CONVECTION ISNT AS WIDESPREAD AS FIRST THOUGHT. WERE A BIT LESS UNSTABLE THAN THIS TIME YESTERDAY...PROBABLY BECAUSE THE SENSIBLE HEAT WAS CONSUMED IN EVAPOTRANSPIRATION. ALSO...WE COULD BE SEEING SOME MID LEVEL SUBSIDENCE ON THE NORTHERN EDGE OF THE ANTICYCLONIC GYRE ABOVE HRCN ADRIAN. SAW SOME CONVECTION DEVELOP ON OLD BOUNDARIES AND OVER THE MOUNTAINS TODAY...BUT WITH THIS WEAK FLOW REGIME ALOFT...SUBSEQUENT CONVECTIVE DEVELOPMENT IS SENSITIVE TO FORCING VIA CONVERGENCE ALONG OUTFLOW BOUNDARIES...AND WHEN YOU DONT HAVE MUCH IN THE WAY OF OUTFLOW BOUNDARIES...YOU DONT HAVE MUCH IN THE WAY OF THUNDERSTORMS. FOR NOW...WE RECOMMEND THAT THE FLASH FLOOD WATCH BE LEFT UP AS ANY ADDITIONAL RAINFALL...PARTICULARLY OVER THE PERMIAN BASIN...WILL POSE PROBLEMS. BUT WE CAN LOWER POPS DOWN TO CHANCE CATEGORY FOR THE REMAINDER OF TONIGHT. OTHER THAN SOME TWEAKING OF SKIES OVERNIGHT...NO OTHER CHANGES TO THE ONGOING FORECAST ARE SUGGESTED. LBB ZONES OUT...ABQ LOOKS FINE AT THIS END...70.
