Area forecast discussion, Jun 11, 8:43 PM CDT, 2 hours 28 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE SAN ANGELO TX 843 PM CDT WED JUN 11 1997 AN AREA OF SHOWERS AND STORMS STRETCHING FROM SOUTHWEST TEXAS... THROUGH THE PERMIAN BASIN AND SOUTH PLAINS AND INTO THE SOUTHERN PANHANDLE...CONTINUES TO MOVE STEADILY EASTWARD. STORMS HAVE SHOWED SOME SIGNS OF WEAKENING DURING THE LAST HOUR...BUT WITH THE 21Z RUC FORECASTING A LOW LEVEL JET OF 30 TO 40 KNOTS SETTING UP BY MIDNIGHT...THINK THE STORMS WILL AT LEAST PERSIST INTO THE WESTERN HALF OF THE AREA. THUS...FAVOR INCREASING POPS ACROSS THE NORTHERN EDWARDS PLATEAU...CONCHO VALLEY...AND WESTERN BIG COUNTRY INTO THE CHANCE CATEGORY. AS FOR THE EASTERN HALF...MUCH DEPENDS ON WHAT HAPPENS OVER THE NEXT HOUR...BUT WITH THE FAIRLY SLOW MOVEMENT AND SLOW WEAKENING...THINK WIDELY SCATTERED MAY WORK FOR NOW. CAN ALWAYS INCREASE CHANCES LATER IF THE STORMS FAIL TO DECREASE. AREA BESET BY HEAVY RAINFALL OVER THE LAST WEEK. RADAR TRENDS SEEM TO INDICATE THE STEADY MOVEMENT OF THE STORMS SHOULD COMBINE WITH THE WEAKENING TO PREVENT EXCESSIVE RAINFALL. HOWEVER...WILL CLOSELY MONITOR. TEMPERATURES AND WINDS LOOK ON TRACK FOR NOW. PMCCULLOUGH
