Area forecast discussion, Jun 11, 2:30 PM CST, 36 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE TULSA OK 330 PM CDT SAT JUN 11 2011 .DISCUSSION... THE MAIN FORECAST CHALLENGE WILL BE CONVECTIVE CHANCES OVER THE NEXT 24 HOURS. A STALLED OUT FRONTAL BOUNDARY LIES FROM NEAR OR JUST SOUTH OF THE I-40 CORRIDOR IN OKLAHOMA...ARCING BACK TO THE NORTHWEST INTO THE CENTRAL HI PLAINS...AND TO THE NORTHEAST ACROSS AR INTO SE MISSOURI. SCATTERED SFC BASED THUNDERSTORMS HAVE DEVELOPED OVER THE PAST HOUR ALONG AND SOUTH OF THE BOUNDARY...AND A FEW WIDELY SCATTERED MAINLY ELEVATED SHOWERS AND THUNDERSTORMS EXIST NORTH OF THE BOUNDARY. THE CAP IS WEAKER TODAY COMPARED TO YESTERDAY...AND MID LEVEL WINDS ARE WEAKER AS WELL. THUS...EXPECT SCATTERED MOSTLY DISORGANIZED PULSE TYPE CONVECTION THROUGH SUNSET ACROSS MUCH OF THE REGION. A STRONG JET ALOFT WILL HELP VENTILATE THE STORMS...SO A FEW SEVERE STORMS ARE POSSIBLE WITH DAMAGING WINDS AND LARGE HAIL. FOCUS THEN TURNS TO THE WEST FOR TONIGHT. STORMS ARE EXPECTED TO FORM IN THE UPSLOPE FLOW REGIME ON THE HI PLAINS THIS AFTERNOON AND EVENTUALLY GROW UPSCALE INTO AN MCS /STORM COMPLEX/ TONIGHT AND MOVE GENERALLY EAST. THE TRACK OF THE SYSTEM IS STILL A BIT UNCERTAIN...AND REALLY DEPENDS ON HOW FAR NORTH THE BOUNDARY RETREATS. THE COMPLEX WILL LIKELY TRAVEL ALONG OR TO THE NORTH OF THE FRONT TONIGHT...AND AFTER PERUSING ALL OF THE AVAILABLE MODEL DATA THIS IS MOST LIKELY TO BE NEAR THE KS/OK BORDER. BY SUNDAY MORNING...STORMS MAY DEVELOP TO THE SOUTHEAST INTO NW AR AS THEY ROUND THE EDGE OF THE CAPPING EML. DAMAGING WINDS WILL BE THE PRIMARY HAZARD. UPPER HEIGHTS WILL RISE DURING THE DAY ON SUNDAY AND THE EML WILL SPREAD NORTHEAST ACROSS THE FORECAST AREA AS THE FRONT RETREATS BACK TO THE NORTH. THUS...PRECIP CHANCES WILL TAPER OFF FROM SOUTHWEST TO NORTHEAST WITH TIME. BY MONDAY...MODELS SHOW SOUTHWEST SFC WINDS AND HOT TEMPERATURES...WITH HIGHS IN THE UPPER 90S AND POSSIBLY NEAR 100 DEGREES TO THE WEST OF TULSA. THE RIDGING ALOFT WILL BE FAIRLY SHORT-LIVED...AS MODELS FORECAST A STRONG UPPER TROUGH OVER THE CENTRAL AND NORTHERN PLAINS BY WEDNESDAY. THIS SYSTEM WILL PUSH A FRONT INTO OUR REGION LATE TUESDAY INTO WEDNESDAY...AND AT LEAST SOME CHANCE FOR THUNDERSTORMS CAN BE EXPECTED WITH IT. THE GFS AND ECMWF CONTINUE TO DISAGREE WITH THE DETAILS IN THE LATER PERIODS. THE GFS SHOWS MORE RIDGING ALOFT OVER THE FORECAST AREA WITH THE RETREATING FRONT LIFTING NORTH INTO KS/MO BY FRIDAY. THE ECMWF KEEPS THE FRONT FARTHER SOUTH AND IS MORE ZONAL WITH THE PATTERN ALOFT. THE CANADIAN ENSEMBLES TEND TO FAVOR THE GFS SOLUTION...HOWEVER GIVEN THE PERSISTENCE OF THE ECMWF...SLIGHT CHANCE POPS ACROSS THE NORTH ARE WARRANTED FOR FRIDAY.
