Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this severe thunderstorm warning while it was in force. That is not proof nothing happened: reports are thin where few people live.

AREA FORECAST DISCUSSION...UPDATED NATIONAL WEATHER SERVICE MIDLAND/ODESSA TX 457 PM CDT THU MAY 20 2004 .UPDATE... PUBLIC PRODUCTS UPDATED FOR WS223. && .PREV DISCUSSION... LOW LEVEL MOISTURE HANGING TOUGH ACROSS WESTERN AND CENTRAL PORTIONS OF THE CWFA THIS AFTERNOON...AND SO IS THE CAP. ISOLATED CONVECTION HAS DEVELOPED OVER THE HIGHER TERRAIN OF THE SACRAMENTO AND DAVIS MOUNTAINS AND WE EXPECT CONTINUED DEVELOPMENT THROUGH THIS AFTERNOON. COLD POOLS GENERATED BY THIS CONVECTION MAY AID IN FURTHER DEVELOPMENT FROM THE SOUTHEASTERN NEW MEXICAN PLAINS SOUTH ACROSS THE UPPER TRANS PECOS AND WESTERN PERMIAN BASIN LATE THIS AFTERNOON THROUGH THIS EVENING. WE EXPECT THIS CONVECTION TO DIMINISH A FEW HOURS AFTER SUNSET. GIVEN DRY SUBCLOUD CONDITIONS AND WEAK SHEAR...THE SEVERE THREAT IS LOW (BUT NONZERO) AND WILL BE CONFINED TO MARGINALLY SEVERE HAIL AND WIND. HAVE TRENDED TOWARD A BLEND OF PERSISTENCE AND ETA MOS GUIDANCE FOR GRIDS TONIGHT. EXPECT LOW STRATUS TO REDEVELOP DURING THE EARLY MORNING HOURS OVER THE EASTERN THIRD OF THE CWFA. WINDS WILL REMAIN UP OVERNIGHT ACROSS THIS AREA AS WELL BENEATH A DEVELOPING 45KT LOW LEVEL JET. ANTICIPATING ISOLATED CONVECTIVE ACTIVITY TO BE ABLE TO PUSH FURTHER EAST INTO THE PLAINS LATE FRIDAY AND FRIDAY NIGHT AS THE WINDS ALOFT CONTINUE TO STRENGTHEN AND TURN MORE ZONAL IN CONJUNCTION WITH THE SURFACE TROUGH. BY SATURDAY A SIGNIFICANT SHORTWAVE EJECTING THROUGH THE WESTERN PLAINS AHEAD OF THE NEXT WESTERN TROUGH WILL HELP MIX THE DRYLINE FURTHER EAST INTO THE CENTRAL OR EASTERN PERMIAN BASIN. ECMWF HAS BEEN CONSISTENT IN HANGING UP THE DRY LINE ACROSS THE EASTERN BASIN AND HISTORY REASONABLE ENOUGH TO MAINTAIN LOW ORDER POPS ACROSS THIS REGION LATE SATURDAY AND SATURDAY EVENING. ANOTHER SIGNIFICANT WAVE AHEAD OF THE SECOND WESTERN TROUGH WILL MOVE ACROSS THE CENTRAL PLAINS SUNDAY. ETA AND GFS MIX THE DRY LINE EAST OF THE COUNTY WARNING AREA EXCEPT AGAIN THE ECMWF AND NOGAPS...WILL CONTINUE TO PAINT THE SILENT POP SUNDAY IN THE EAST AND LET LATER SHIFTS MONITOR. BY MONDAY THROUGH NEXT THURSDAY THE MEDIUM RANGE GUIDANCE IS IN FAIRLY REASONABLE AGREEMENT IN HOLDING THE WESTERN TROUGH AND MOISTURE FURTHER WEST. CONTINUED THE ISOLATED POPS IN THE HIGHER TERRAIN MONDAY. WITH THE TROUGH SO FAR WEST DONT THINK ANY CONVECTION THAT DOES FIRE WILL DRIFT VERY FAR INTO THE PLAINS UNLESS A DECENT SHORTWAVE TROUGH EJECTS AHEAD OF THE SECOND WESTERN TROUGH. IN ADDITION WARMING TEMPERATURES ALOFT WOULD HAVE TO BE OVERCOME EAST OF THE DRY LINE. FIRE WEATHER WILL BECOME A CONCERN ESPECIALLY WESTERN SECTIONS THIS WEEKEND AND POSSIBLY BEYOND AS THE DRYLINE MIXES EAST WITH DRYING AND BREEZY CONDITIONS IN ITS WAKE. FIRE DANGER AND FUEL MOISTURE WILL NEED TO BE MONITORED ALONG WITH RH/S AND WIND SPEEDS. && .MAF WATCHES/WARNINGS/ADVISORIES... TX...NONE. NM...NONE. &&
