AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE LUBBOCK TX 315 PM CDT SAT AUG 21 2004 .SHORT TERM... MUCH OF THE SPLNS HAVE SLOWLY CLEARED OUT AFTER THE MORNING CLOUDS/SCT STORMS. LOOKS LIKE THE SE COUNTIES ARE FILLING IN WITH LOW CLOUDS AGAIN AFTER SEEING SOME SUN WITH TEMPS GETTING TO AROUND 80. 18Z RUC FCST SNDGS SHOW CONVECTIVE TEMPS IN THE MID 80S ACROSS THE SRN COUNTIES EARLY THIS EVE. WITH THE BL ACROSS THE ROLLING PLAINS STABILIZED BY THE MORNING CONVECTION...NOT SURE WHETHER IT CAN RECOVER IN TIME FOR ANY SFC-BASED CONVECTION THIS EVE. WILL WATCH CAREFULLY AS STORM DVLPMNT IS CURRENTLY OCCURRING TO THE SOUTH AROUND SWEETWATER...FCST CAPES ARE PRETTY HIGH IN THIS AREA IF THEY CAN CONTINUE TO HEAT UP. SEVERAL SMALL-SCALE WAVES WILL BE MOVING THROUGH THE MEAN WNW FLOW ACROSS THE WRN AND CENTRAL US. AS WE FOUND OUT THIS MORNING...TIMING AND PATH OF THESE SMALLER WAVES CAN BE TRICKY. ONE SUCH WAVE IS CURRENTLY MOVING ACROSS THE 4-CORNERS REGION. SAT SHOWS CONVECTION IS STARTING TO FIRE ACROSS THE NM MTNS AGAIN. FOR TONIGHT...WITH THE APPROACH OF THE WAVE...INCREASED LLJ AND WEAK ISEN LIFT...KEEPING A CHC OF TSTMS OVERNIGHT SEEMS WARRANTED. LOW CLOUDS RAPIDLY FILLED IN AROUND MIDNIGHT YSDY...DID NOT GO WITH QUITE AS AGGRESSIVE WITH THEM TONIGHT...BUT CERTAINLY MAY SEE SOME AREAS...ESPECIALLY OFF THE CAPROCK...SOCKED IN BY SUN MORNING FOR A WHILE. IT LOOKS LIKE INCREASED WESTERLY FLOW TOMORROW BEHIND SHTWV WILL INDUCE A LEE-SIDE TROF STRETCHING SOUTH INTO THE WRN SPLNS THUS INCREASE SRLY WINDS...REDUCING ATMOS MOISTURE A BIT AND AIDING TO WARM THE SPLNS UP. WE MAY SEE THE FIRST 90 DEGREE TEMP IN 16 DAYS AT LBB IF LOW CLOUDS DO NOT LAST VERY LONG. ALTHOUGH NOTHING TO PIN DOWN CONVECTIVE CHCS...WITH THE WARMER TEMPS AND A BIT OF TROFFINESS LINGERING OVER THE AREA...SCT TSTM DVLPMNT DURING THE LATE AFTN LOOKS POSSIBLE...MAINLY ACROSS THE ROLLING PLAINS. .LONG TERM... POLAR VORTEX OVER HUDSON BAY CANADA WILL FINALLY BEGIN MOVING EASTWARD RESULTING IN A MAJOR PATTERN CHANGE OVER THE LOWER 48 EARLY NEXT WEEK. HEIGHTS WILL RISE FROM EASTERN CANADA ALONG THE EASTERN SEABOARD...WHILE AN UPPER TROUGH WILL TAKE SHAPE ACROSS THE INTERMOUNTAIN WEST. WEST TEXAS WILL BEGIN TO SEE MORE TYPICAL AUGUST WEATHER WITH DIMINISHING RAIN CHANCES. UPPER HEIGHTS WILL RISE MONDAY AND TUESDAY WITH A S/SW LOW LEVEL WIND...SO 90 DEGREE DAYTIME HIGHS WILL LIKELY RETURN. CERTAINLY CANNOT RULE OUT ISOLD SHOWERS AND THUNDERSTORMS BUT MAY BEGIN TO SEE STRENGTHENING LOW TO MID LEVEL CAP WHICH WILL MAKE DEEP MOIST CONVECTION HARDER TO COME BY. ALL IN ALL...PREVIOUS FORECAST IN GOOD SHAPE WITH ONLY MINOR TWEAKS. GFS DOES BRING SOME SUB TROPICAL MOISTURE OVER WEST TEXAS MID WEEK WITH MINOR SOUTHERN STREAM SHORTWAVE. AS MAIN UPPER TROUGH DEEPENS OVER THE WEST WEDNESDAY AND THURSDAY...MAY SEE WINDS INCREASE FROM THE SOUTH WITH DEEPENING LEE SIDE SURFACE TROUGH. FLOW IS PROGGED TO FLATTEN TOWARD THE END OF THE 7 DAY FCST PERIOD AS UPPER TROUGH LIFTS EASTWARD ACROSS THE CENTRAL PLAINS. && .PRELIMINARY POINT TEMPS/POPS...
