AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE TULSA OK 623 AM CDT FRI APR 2 2010 .AVIATION... CONCERNING TAF SITES KTUL/KRVS/KMLC/KXNA/KFYV/KFSM. FOR THE 12Z TAFS... SHOWERS AND THUNDERSTORMS... POSSIBLY SEVERE... WILL MOVE INTO THE REGION FROM THE WEST THIS MORNING... AFFECTING EASTERN OKLAHOMA TAF SITES. THIS ACTIVITY WILL LIKELY WEAKEN OR DISSIPATE BEFORE REACHING OUR ARKANSAS TAF SITES. HOWEVER... ANOTHER ROUND OF SEVERE WEATHER IS EXPECTED THIS AFTERNOON... LIKELY AFFECTING ARKANSAS TAF SITES. && .PREV DISCUSSION... /ISSUED 343 AM CDT FRI APR 2 2010/ DISCUSSION... DRYLINE HAS PUSHED THROUGH NORTHWEST OKLAHOMA DURING THE EARLY MORNING HOURS WITH INITIAL CONVECTION HAVING WANED...WITH RENEWED STORM DEVELOPMENT NOTED OVER THE SOUTHWESTERN TEXAS PORTION OF THE DRYLINE. SATELLITE IMAGERY / RUC ANALYSIS SUPPORT ONE MID LEVEL SPEED MAX NOW ENTERING FAR SOUTHWEST TEXAS...WITH ANOTHER UPSTREAM OVER WESTERN NEW MEXICO. PRIMARY TROUGH AXIS IS PROGGED TO BECOME INCREASINGLY NEGATIVELY TILTED WHICH IS SUPPORTED BY RECENT TRENDS IN DOWNSTREAM CIRRUS SHIELD. CORRESPONDING SYNOPTIC FORCING IS MORE THAN SUFFICIENT TO SPARK ELEVATED EARLY MORNING CONVECTION WITHIN LOW LEVEL MOIST AXIS...WITH MOST RECENT RUC SOUNDINGS INDICATING VERY LITTLE ELEVATED CINH REMAINS JUST TO THE WEST OF THE FORECAST AREA. THIS ALL SUPPORTS MODEL CONSENSUS IN BREAKING OUT AND/OR EXPANDING ONGOING CONVECTION INTO THE FORECAST AREA DURING THE MORNING HOURS. THIS CONVECTION WILL INITIALLY TAP STEEP LAPSE RATES POSING A LOW SEVERE WEATHER RISK BEFORE CONTAMINATING AND REDUCING THE AVAILABLE INSTABILITY. A PERIOD OF ONGOING BUT SUB- SEVERE CONVECTION IS LIKELY FOR MUCH OF THE DAY. ATTENTION WILL FOCUS TO ANY BOUNDARY LAYER RECOVERY BY AFTERNOON ALONG THE ADVANCING DRY LINE...AND ALSO TO THE PLACEMENT OF THE NEXT MID LEVEL SPEED MAX FORECAST TO TRANSLATE INTO NORTH TEXAS BY AFTERNOON. VARIOUS MODEL QPF SUGGEST ANOTHER ROUND OF STORMS DEVELOPING IN ADVANCE OF THIS FEATURE...AND SPREADING NORTHWARD INTO SOUTHEAST OKLAHOMA AND WESTERN ARKANSAS WITH AN INCREASING RISK OF SEVERE WEATHER. THE DEEP BACKING FLOW ALOFT ALONG WITH AFOREMENTIONED STRONG FORCING WILL FAVOR BANDS OF STORMS WITH WIND POTENTIAL LIKELY THE GREATEST IMPACT AND ANY TORNADIC RISK RELEGATED TO BRIEF LEWP COUPLETS. STORMS SHIFT EAST OF THE FORECAST AREA BY MIDNIGHT...WITH COOLER AND LESS WINDY CONDITIONS FOR SATURDAY. SOUTHERLY WINDS QUICKLY RETURN SUNDAY ALONG WITH INCREASING LOW LEVEL MOISTURE. THUNDERSTORM CHANCES ARE NOT ZERO WITHIN THIS WARM MOIST ADVECTION PERIOD BUT ENOUGH UNCERTAINTY IN PLACEMENT AND COVERAGE KEEPS MENTION OUT OF THE FORECAST. THE EXPANDING WARM SECTOR ENVELOPES MUCH OF THE SOUTHERN PLAINS AHEAD OF THE NEXT COLD FRONT...WHICH THE 00Z ECMWF AND 00Z GFS ENSEMBLE MEAN BRING THROUGH THE AREA TUESDAY NIGHT AND EARLY WEDNESDAY. STRONG TO SEVERE STORMS ARE LIKELY WITH THIS FRONTAL PASSAGE. DRY AND SEASONAL TEMPS FORECAST FOR LATE NEXT WEEK. && .TSA WATCHES/WARNINGS/ADVISORIES... OK...NONE.
