Area forecast discussion, Jun 2, 3:28 PM CDT, 3 hours 18 minutes before
AREA FORECAST DISCUSSION...CORRECTED NATIONAL WEATHER SERVICE MIDLAND/ODESSA TX 328 PM CDT TUE JUN 2 2009 .DISCUSSION... CORRECTED TO READ WESTERN OKLAHOMA INSTEAD OF EASTERN OKLAHOMA. 00Z SOUNDING FROM YESTERDAY SHOWED MID LEVEL CAP THAT PREVENTED CONVECTION FROM DEVELOPING. TODAY THERE IS MOISTURE INCREASING IN THE MID LEVELS WHICH IS HELPING CONVECTION TO DEVELOP IN THE MOUNTAINS WEST OF THE PECOS RIVER. HOWEVER THE MAIN AREA TO KEEP AN EYE ON IS AN OUTFLOW BOUNDARY FROM CONVECTION IN THE PANHANDLE AND WESTERN OKLAHOMA THIS MORNING APPROACHING THE NORTHEASTERN CWA. THUNDERSTORMS ARE RAPIDLY DEVELOPING ALONG THIS BOUNDARY AND THE OUTFLOW FROM THESE STORMS WILL KEEP PUSHING IT SOUTH WITH FURTHER CONVECTIVE DEVELOPMENT LIKELY. MARGINALLY SEVERE STORMS ARE POSSIBLE WEST OF THE PECOS...BUT ONCE AGAIN THE GREATEST SEVERE POTENTIAL WILL LIE NORTHEAST OF MAF WHERE NAM SHEAR VALUES OF 40KTS AND CAPE OF 2.5KJ/KG ARE LOCATED. ISOLATED BRIEF TORNADOES WILL BE POSSIBLE...BUT PERHAPS THE BIGGER THREAT COULD BE VERY LARGE AND DAMAGING HAIL. A WEAK SHORTWAVE WILL KEEP CONVECTION GOING A LITTLE LONGER THAN USUAL TONIGHT ESPECIALLY IN THE EASTERN CWA...BUT INCREASING STABILITY WILL ULTIMATELY DIMINISH CONVECTION OVERNIGHT. A COLD FRONT WILL MOVE THROUGH TOMORROW AND COULD SERVE AS A FOCUS FOR CONVECTION TOMORROW AFTERNOON MAINLY ALONG THE TRANS PECOS REGION...HOWEVER A MORE STABLE BOUNDARY LAYER WILL GREATLY REDUCE THE SEVERE THREAT FROM TODAY. BY THE END OF THE WEEK AN UPPER LEVEL RIDGE WILL STRENGTHEN AND CENTER OVER WEST TEXAS INHIBITING STORM DEVELOPMENT AND CAUSING TEMPS TO RISE INTO THE UPPER 90S AND 100S. THIS RIDGE WILL SLOWLY MOVE EAST BY EARLY NEXT WEEK WHICH SHOULD ALLOW FOR A RETURN OF SOUTHWEST FLOW ALOFT AND MAX TEMPS TO DROP SLIGHTLY. COULD SEE SPORADIC CONVECTION DEVELOP ONCE AGAIN LATE IN THE PERIOD WITH THE RETURN OF SW UPPER FLOW...BUT FOR NOW WILL LEAVE IT OUT OF THE FORECAST. HENNIG && .PRELIMINARY POINT TEMPS/POPS...
