Area forecast discussion, Apr 23, 5:02 PM CST, 6 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE NORMAN OK 602 PM CDT THU APR 23 2009 .AVIATION... HIGH-BASED SHOWERS AND THUNDERSTORMS MAY GENERATE ISOLATED WIND GUSTS OF 40 TO 45 KTS ACROSS PARTS OF SOUTHWEST OKLAHOMA AND WESTERN NORTH TEXAS EARLY THIS EVENING. MODERATE SOUTH WINDS WILL CONTINUE OVERNIGHT AT MOST TERMINAL LOCATIONS. PATCHES OF SCATTERED TO BROKEN STRATOCUMULUS CLOUDS WILL SPREAD INTO PARTS OF SOUTHERN AND CENTRAL OKLAHOMA FRIDAY MORNING. MEANWHILE... GUSTY SOUTH WINDS WILL CONTINUE THROUGH FRIDAY. && .PREV DISCUSSION... /ISSUED 340 PM CDT THU APR 23 2009/ DISCUSSION... HOT AND DRY WEATHER CONTINUES THIS AFTERNOON WITH TEMPERATURES CLIMBING INTO THE MID 90S AGAIN IN THE SOUTHWEST. HIGH BASED CONVECTION IS OCCURRING IN THE TEXAS SOUTH PLAINS AND APPROACHING THE SOUTHWEST PORTION OF THE AREA. MUCH OF THE PRECIPITATION CLOSEST TO THE AREA APPEARS TO BE VIRGA... BUT THERE ARE MORE SIGNIFICANT STORMS FARTHER SOUTHWEST AND SHORTWAVE SUPPORTING THIS CONVECTION WILL BE MOVING TOWARD THE AREA OVERNIGHT. ALTHOUGH MODELS GENERALLY KEEP THIS PRECIPITATION AWAY FROM THE AREA... CURRENT DEVELOPMENT IS SUFFICIENT THAT SLIGHT CHANCE POPS ARE WARRANTED IN THE SOUTHWEST THIS EVENING. LOW LEVEL MOISTURE WILL BE ON THE INCREASE TONIGHT INTO TOMORROW AS MOISTURE IS ADVECTING NORTH THROUGH TEXAS WITH MODERATE SOUTH WINDS PERSISTING OVERNIGHT AND INCREASING AGAIN TOMORROW. THIS INCREASING MOISTURE COMBINED WITH A PERSISTENT WESTERN UNITED STATES TROUGH AND SURFACE BOUNDARIES IN OR NEAR THE AREA WILL SET THE STAGE FOR A PROLONGED PERIOD WITH A POTENTIAL FOR STORMS. THE MEDIUM RANGE MODELS STILL SHOW MULTIPLE STORM COMPLEX EVENTS FROM THIS WEEKEND THROUGH MID WEEK AFFECTING THE AREA WITH ASSOCIATED RISKS OF SEVERE WEATHER AND/OR HEAVY RAINFALL AND FLOODING POTENTIAL. BUT OF COURSE DAY-TO-DAY FORECASTING WILL BE COMPLICATED IN THE EXTENDED PERIODS IN THAT PRECIP CHANCES AND TO SOME EXTENT TEMPERATURES WILL BE AFFECTED BY THE CONVECTIVE EVOLUTION AND MESOSCALE PROCESSES THAT CAN NOT BE WELL-FORECAST THIS FAR IN ADVANCE. SO WHILE SCENARIOS ON SPECIFIC DAYS ARE QUITE UNCERTAIN...
