NWS Midland/Odessa, TX wrote its last area forecast discussion before the first event at May 9, 1:00 PM CST, 1 hour 30 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MIDLAND/ODESSA TX 200 PM CDT SUN MAY 9 2004 .SHORT TERM... A COUPLE OF SHORTWAVE TROUGHS...ONE NEAR EL PASO...THE OTHER OVER CHIHUAHUA ARE EXPECTED TO TRANSLATE EAST INTO THE CWA LATE THIS AFTERNOON AND OVERNIGHT. THE MID LEVEL SUPPORT AHEAD OF THESE WAVES...ALONG WITH AN INCREASING LOW LEVEL JET...APPEARS SUFFICIENT TO AID TSRA IN MOVING FURTHER EAST OVER THE PLAINS TONIGHT. THEREFORE...WILL ADD POPS TO PORTIONS OF THE PLAINS FOR THE OVERNIGHT PERIOD. AS WITH THE STORMS YESTERDAY AND THE DAY BEFORE...WEAK WINDS ALOFT SHOULD PRECLUDE MANY SEVERE STORMS THIS AFTERNOON AND EVENING. HOWEVER...A COUPLE OF STORMS COULD ORGANIZE SUFFICIENTLY TO YIELD MARGINALLY SEVERE HAIL OR WINDS...BUT MAINLY BEFORE 10/02Z. THE LOW LEVEL JET WILL AGAIN PUSH MOISTURE BACK WEST TO THE SURFACE TROUGH AXIS SITUATED OVER THE HIGHER TERRAIN. EXPECTING ANOTHER ROUND OF LOW CLOUDS TO DEVELOP ON SAME...GENERALLY EAST OF THE PECOS RIVER. MIN TEMPERATURES IN GRIDS LOOKED PRETTY GOOD...SO ONLY TWEAKED A FEW. OTHERWISE...GRIDS ARE IN PRETTY GOOD SHAPE. .LONG TERM... LIFT ASSOCIATED WITH SHORTWAVE TROUGHS EVIDENT IN SATELLITE DATA TODAY...ESPECIALLY ACROSS CENTRAL CHIHUAHUA AND NOW JUST SOUTH OF THE BIG BEND AREA. THESE SHORTWAVES AND ASSOCIATED ENERGY WILL CONTINUE TO AFFECT OUR AREA THROUGH MONDAY. WITH CONTINUED MOISTURE AND INSTABILITY IN THE LOWER LEVELS...WILL KEEP GENERALLY SLIGHT CHANCE AND ISOLATED POPS GOING OVER MUCH OF THE AREA MONDAY AFTERNOON. WILL ALSO RETAIN THE SLIGHT CHANCE POPS OVER THE PERMIAN BASIN...WESTERN LOW ROLLING PLAINS FOR TUESDAY. DRYLINE SHOULD START SHARPENING UP BY THEN AND BEGIN MAKING PROGRESS FURTHER EAST THAN LATELY. THIS SHOULD PROVIDE A MORE LEGITIMATE FOCUSING MECHANISM FOR CONVECTION TUESDAY AFTERNOON AS THE SHORTWAVE MOVES OFF TO THE NORTHEAST. HEIGHT GRADIENTS ALOFT ALSO BEGIN TO TIGHTEN VERY SLIGHTLY TUESDAY AFTERNOON WHICH MAY PROVIDE ADDITIONAL DYNAMIC SUPPORT FOR MORE ORGANIZED CONVECTION. WILL CONTINUE TO HOLD OFF GETTING TOO SPECIFIC HOWEVER. HEIGHT GRADIENTS WILL BE SHARPENING DUE TO A DEEPENING TROUGH OVER THE WESTERN U.S. TWO SHORTWAVES WILL COMBINE TO DEEPEN THE WESTERN TROUGH. ONE NOW OFF THE PACIFIC NORTHWEST COAST WILL MOVE INLAND OVER NORTHERN CA TONIGHT. THE SECOND SHORTWAVE NOW OVER THE GULF OF ALASKA WILL DIVE SOUTH ALONG THE WESTERN CANADIAN COAST AND FURTHER DEEPEN THE TROUGH WHILE KICKING THE FIRST SHORTWAVE EAST. AS THE LEE TROUGH IS SUSTAINED THROUGH THE MIDDLE OF THE WEEK BY INCREASING FLOW ALOFT...SIGNIFICANT SFC MOISTURE WILL STRUGGLE TO MAKE IT BACK WEST OF THE PERMIAN BASIN AREA EACH DAY DUE TO STRONG SOUTHWESTERLY LOW- LEVEL FLOW. FOR THIS REASON WILL KEEP THE MAINLY DRY FORECAST GOING. MAY ADD IN ISOLATED POPS FOR WESTERN LOW ROLLING PLAINS...LOWER TRANS PECOS OR EASTERN PERMIAN BASIN LATER IN THE WEEK. WITH TIMING OF SHORTWAVES AND/OR DYNAMIC SUPPORT QUESTIONABLE AS FAR OUT AS THURSDAY AND FRIDAY...PLACEMENT OF PRECIP ALSO QUESTIONABLE... ESPECIALLY WITH THE DRIER TREND OF THE MODELS THIS PERIOD. MADE ONLY MINOR ADJUSTMENTS TO TEMPERATURES THROUGHOUT THE WEEK. && .PRELIMINARY POINT TEMPS/POPS...
