Area forecast discussion, Jun 6, 10:14 PM CDT, 4 hours 34 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE NORMAN OK 1015 PM CDT SUN JUN 6 2004 LATEST RUC AND ETA MODELS ARE CONSISTANT WITH TRYING TO DRIFT THE MCV NORTHEAST INTO SOUTH CENTRAL OKLAHOMA OVERNIGHT. WITH THE STEERING FLOW AROUND THIS SYSTEM BEING WEAK... CONFIDENCE IN THIS SOLUTION IS NOT OVERLY HIGH... BUT SUFFICIENT TO INCREASE POPS SOMEWHAT BACK NORTH TOWARDS CENTRAL OKLAHOMA. ALTHOUGH THE RICH LOW LEVEL FLOW IS LIKELY DISRUPTED BY THE NORTH TEXAS COMPLEX... WHICH CONTINUES TO PUSH SOUTHEAST... BELIEVE SUFFICIENT MOISTURE STILL AVAILABLE TO SUPPORT AT LEAST SOME MID LEVEL SHWRS/TSTMS FARTHER NORTH IF THE UPPER SYSTEM DOES INDEED DRIFT NORTHEAST. && 32 910 PM CDT SUN JUN 6 2004 MCV LOCATED SOUTHEAST OF WICHITA FALLS WAS CONTINUING TO SUPPORT A LARGE AREA OF CONVECTION OVER NORTH CENTRAL TEXAS INTO SOUTH CENTRAL OKLAHOMA THIS EVENING. WITH ONLY VERY SLOW MOVEMENT OF THE MCV EXPECTED OVERNIGHT... WILL LIKELY SEE SHWRS/TSTMS PERSIST ACROSS THE RED RIVER VALLEY OF SOUTH CENTRAL OKLAHOMA FOR SEVERAL MORE HOURS. EVENING RAOB DATA INDICATES GOOD MOISTURE MOVING INTO THIS SYSTEM WITH FWD INDICATING A 16C DEWPOINT AND SOUTH WINDS AT 30 KT AT 850 MB. OCCASIONAL HEAVY RAIN WILL BE POSSIBLE IN OUR CWA... BUT BELIEVE MAIN FLOOD PROBLEMS WILL REMAIN SOUTH OF THE RED RIVER. MESONET SHOWING GENERALLY ONE-HALF INCH OR RAIN OR LESS ACROSS SOUTHERN OKLAHOMA SO FAR. MEANWHILE... RADAR TRENDS INDICATE THE HEAVIEST BAND OF CONVECTION WAS SPREADING SOUTHEAST TOWARDS THE DFW AREA... WHICH MAY TEND TO REDUCE THE RICHER MOISTURE FLOW INTO SOUTHERN OKLAHOMA. TREND FOR MOST OF THE EVENING HAS BEEN FOR CONVECTION TO WEAKEN AS IT SPREAD NORTH ACROSS THE RED RIVER...AND EXPECT THIS PATTERN TO CONTINUE. WILL UPDATE THE FORECAST TO CONFINE HIGHEST POPS OVERNIGHT TO THE RED RIVER VALLEY AREA OF SOUTH CENTRAL OKLAHOMA. WILL ALSO LOWER OVERNIGHT LOWS IN AREAS WITH PCPN. && 32 238 PM CDT SUN JUN 6 2004 .DISCUSSION... WITH CURRENT DEVELOPMENT AROUND VORT MAX...HAVE ADJUSTED 1ST/2ND PERIOD POPS A BIT. UPDATED NUMBERS BELOW. MAIN CHANGE TO SHORT TERM PERIODS IS TO CONTINUE POPS OVER MAINLY SOUTH CENTRAL AND SOUTHEAST OKLAHOMA ZONES...WHERE WELL DEFINED VORT CENTER WILL BE SLOW TO GO AWAY. THIS WEAKNESS IN WEAK RIDGE WILL ESSENTIALLY PROVIDE AN UNCAPPED...MOIST/UNSTABLE...ATMOSPHERE ESPECIALLY ON EASTERN PERIPHERY. ALTHOUGH LOW LEVEL FORCING MECHANISMS WILL BE HARD TO COME BY...DIURNALLY DRIVEN ISOLATED-SCATTERED CONVECTION LIKELY. FOR NOW...POPS WILL BE CONFINED TO EXTREME SOUTHEAST ZONES...BUT AS MODELS TRY TO RESOLVE THIS FEATURE...THESE POPS MAY NEED TO BE EXPANDED INTO CENTRAL OK AND WRN NTX COUNTIES IN FUTURE ISSUANCES. ELSEWHERE...VERY WARM TEMPERATURES AND DRY CONDITIONS EXPECTED. PREVIOUSLY MENTIONED DIURNAL TYPE ACTIVITY IS EXPECTED TO LOOSE GRIP ON AREA BY THURSDAY. AT THE SAME TIME...DRY LINE WILL BEGIN TO TAKE SHAPE AND PERHAPS AFFECT MAINLY WESTERN ZONES BY LATE WEEK. ACTIVE WEEKEND AND EARLY NEXT WEEK STILL POSSIBLE BASED ON LRGFS...BUT CONFIDENCE NOT REAL HIGH...AS FAIRLY LARGE DISCREPANCIES ARE SEEN OVER EASTERN PACIFIC AMONG MEDIUM RANGE MODELS...WHICH WILL HAVE IMPACT ON EVOLUTION/EXTENT OF CYCLOGENESIS AND CENTRAL PLAINS FRONTAL BOUNDARY. FIRST PERIOD POPS WILL BE TWEAKED AT LAST MINUTE WITH ACTIVITY DEVELOPING NEAR MENTIONED VORT CENTER OVER NORTHERN TEXAS. && .PRELIMINARY POINT TEMPS/POPS...
