An isolated supercell thunderstorm produced large hail over the northwest part of Terrell County.

AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MIDLAND/ODESSA TX 219 PM CDT TUE MAY 11 2004 .SHORT TERM... SKIES HAVE CLEARED NICELY OVER THE AREA ALLOWING THE AREA TO DESTABILIZE. DRYLINE FINALLY STARTED MAKING PROGRESS EAST BY 18Z TODAY...AS KCNM WINDS TURNED TO THE WEST AND THE DEWPOINT DROPPED 10F DEGREES. EXPECT THE DRYLINE TO MAKE PRETTY GOOD PROGRESS TO THE EAST AS MIXING INCREASES. WHITE SANDS PROFILER IS SHOWING WEST TO SOUTHWEST WINDS OF 15KT TO 20KT THROUGH 700MB...AND THIS SHOULD CONTINUE TO HELP MIX THE DRYLINE TO THE EAST THROUGH THE LATE AFTERNOON HOURS. RUC DATA ANALYZED A SHORTWAVE OVER SOUTHERN NM AND NORTHERN CHIHUAHUA WHICH WILL MOVE EAST OUT OVER WEST TX THIS EVENING. THIS WILL COMBINE WITH CAPES OF AROUND 1200J/KG AND THE DRYLINE TO INITIATE CONVECTION FROM OUR CWA NORTHWARD...MOST LIKELY IN OUR NORTH AND NORTHEASTERN ZONES. WITH MUCH BETTER VERTICAL SHEAR OVER THE AREA TODAY...EXPECT SOME OF THESE THUNDERSTORMS TO BE BETTER ORGANIZED THAN THE PAST FEW DAYS AND APPROACH SEVERE LEVELS...WITH LARGE HAIL AND DAMAGING WINDS BEING THE MAIN THREATS FROM THESE STORMS. THERE WILL ALSO BE BETTER MOVEMENT TO THESE THUNDERSTORMS TODAY THAN THERE HAS BEEN IN THE PAST FEW DAYS AS WINDS ALOFT AND THROUGH THE MID-LEVELS HAVE BEEN INCREASING OVER THE PAST 24 HOURS. WILL NOT MAKE ANY BIG CHANGES TO THE LOW TEMPERATURES TONIGHT AS THE DRYLINE IS EXPECTED TO MAKE SOME PROGRESS BACK TO THE WEST. .LONG TERM... LONGWAVE TROUGH WILL BE ESTABLISHED OVER THE WESTERN CONUS WEDNESDAY...BEFORE PROGRESSING EAST AND MINORING OUT OVER THE CENTRAL PLAINS BY WEEK/S END. NEARLY ZONAL FLOW ALOFT WILL PREVAIL THEREAFTER WITH OCCASIONAL WEAK SHORTWAVE TROUGHS TRANSLATING EASTWARD OVER THE AREA THROUGH THE END OF THE PERIOD. LOW LEVEL MOISTURE WILL PUSH EAST OF THE CWA WEDNESDAY AFTERNOON ON WEST/SOUTHWEST FLOW ALOFT AND AT THE SURFACE...PRECLUDING THE ADDITION OF ANY POPS FOR WEDNESDAY AND WEDNESDAY NIGHT. ANOTHER SHORTWAVE TROUGH WILL HEAD TOWARD THE CWA ON THURSDAY. EXPECT DRYLINE TO SETUP OVER THE EASTERN ZONES THURSDAY WHICH WILL PROVIDE A LOW LEVEL FOCUS FOR THUNDERSTORM DEVELOPMENT AS AFOREMENTIONED SHORTWAVE TROUGH MOVES OVERHEAD. THEREFORE...HAVE ADDED A SLIGHT CHANCE OF THUNDERSTORMS FOR THE EASTERNMOST ZONES THURSDAY AFTERNOON AND EVENING. SHEAR LOOKS SUFFICIENT FOR ORGANIZED CONVECTION THURSDAY...SO CONSIDERING THE INSTABILITY WE/LL HAVE...SOME SEVERE STORMS WILL BE POSSIBLE. AREAL EXTENT STILL IN QUESTION...SO WILL NOT MENTION SEVERE WORDING IN THE ZONES AT THIS TIME. MOISTURE LINGERS OVER THE EASTERN ZONES FRIDAY AS ANOTHER SHORTWAVE TROUGH ROUNDS THE BASE OF THE LONGWAVE TROUGH. IN ADDITION...A COLD FRONT WILL PUSH INTO THE AREA FRIDAY MORNING...AND PROBABLY PUSH SOUTHWEST OF THE PECOS RIVER BY FRIDAY AFTERNOON. MID LEVEL SUPPORT APPEARS TO BE LACKING...BUT HAVE ADDED A CHANCE OF TSRA TO THE LOWER TRANS PECOS...AND A SLIGHT CHANCE FROM THE BIG BEND REGION TO THE WESTERN LOW ROLLING PLAINS. WENT AHEAD AND MENTIONED THUNDER IN ALL OF THESE LOCATIONS AS GFS INDICATING ATMOSPHERE TO BE AT LEAST MARGINALLY UNSTABLE...EVEN BEHIND THE FRONT INTO EARLY AFTERNOON. ADDED...BUT RELEGATED...A SLIGHT CHANCE OF TSRA FRIDAY EVENING TO THE BIG BEND REGION DESPITE UPPER TROUGH BEING DEPICTED EAST OF THE AREA BY THEN SINCE THERE ARE SOME INDICATIONS A WEAK SHORTWAVE WILL BE TRAILING THE MAIN TROUGH. LEFT A FEW SHOWERS IN THE BIG BEND AREA SATURDAY MORNING...BEFORE DROPPING ALL POPS SATURDAY NIGHT. REFINED THE CHANCES OF SHRA/TSRA SUNDAY THROUGH MONDAY NIGHT AS GFS AND ECMWF DEPICTING UPSLOPE FLOW...WAA OVER SLIGHTLY COOLER AIRMASS...AND A SERIES OF WEAK SHORTWAVES PARADING OVER THE AREA DURING THIS TIME. WARMEST TEMPERATURES SO FAR THIS YEAR APPEAR TO BE IN ORDER WEDNESDAY AS H85 THERMAL RIDGE EXPANDS OVER THE AREA...AND WILL BE AIDED IN WARMING TEMPERATURES BY DOWNSLOPE WINDS. ON THURSDAY... TEMPS WILL BE FAIRLY SIMILAR TO READINGS WEDNESDAY...EXCEPT FOR THE EXTREME EASTERN ZONES WHERE MOISTURE EXPECTED TO INFRINGE. WILL MAKE MINOR TWEAKS WEDNESDAY AND A FEW MORE ON THURSDAY. ON FRIDAY...WILL HAVE TO COOL HIGHS...ESPECIALLY OVER THE NORTHEAST HALF OF THE CWA DUE TO COLD FRONT. WILL TRY NOT TO GET TOO CARRIED AWAY...SINCE IT/S ALMOST MID MAY.
