AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE LUBBOCK TX 307 PM CDT SAT SEP 17 2005 .SHORT TERM... DEEP CONVECTION LOOKING LESS AND LESS LIKELY FOR LATER THIS AFTERNOON AND EVENING. NOT READY TO RULE IT OUT JUST YET...BUT SURFACE TEMPS HAVE RISEN CLOSE TO SUPPOSED CONVECTIVE TEMPS FROM 12Z RAOBS BUT HARDLY ANY CU IF ANY HAS DEVELOPED ANYWHERE NEAR FA. LAPS 19Z IMAGES CONTINUE TO SUGGEST FORMIDABLE CIN OVER MOST OF THE REGION. THE EXCEPTION IS OVER EXTREME SOUTHWEST SECTIONS AND INTO SOUTHEAST NM WHERE PERHAPS A FEW SMALL CU HAVE FORMED PER VISIBLE IMAGE. NAM 18Z RUN STILL BREAKS OUT SOME CONVECTION AFTER 00Z OVER WESTERN SECTIONS AND THERE COULD BE JUST ENOUGH FORCING FOR THIS TO OCCUR SO WILL LEAVE CURRENT POP/WX/QPF GRIDS AS INHERITED WITH ONLY SOME MINOR ADJUSTMENTS. AMOUNT OF INSTABILITY AND VERTICAL WIND PROFILES ARE FAVORABLE FOR SEVERE THUNDERSTORMS SHOULD INITIATION OCCUR AND THIS IS SOMETHING WE WILL HAVE TO WATCH THROUGH THE EARLY EVENING HOURS. ANY STORMS THAT DEVELOP SHOULD WEAKEN QUICKLY AFTER SUNSET. STORMS LOOK EVEN LESS LIKELY ON SUNDAY AFTERNOON AS LOW LEVEL WINDS VEER TO THE SOUTHWEST AND DEWPOINTS DECREASE SOME. WILL KEEP POP GRIDS LESS THAN 20 FOR THE AFTERNOON HOURS. VEERED WIND PROFILE WILL RESULT IN A BETTER DOWNSLOPE COMPONENT THAN WE HAVE HAD LAST FEW DAYS WHICH SHOULD RESULT IN WARMER AFTERNOON TEMPERATURES...ALTHOUGH THE MAV NUMBERS ARE PROBABLY STILL A LITTLE HIGH. .LONG TERM... UPPER RIDGE TO EXPAND WWD OVER WEST TEXAS EARLY IN THE PERIOD. MID/UPPER LEVEL MOISTURE TO BE DISPLACED NWWD AS A RESULT. WILL SEE POPS DECREASE FURTHER MONDAY ALTHOUGH A WEAK COLD FRONT WILL BE ON THE DOORSTEP LATE IN THE DAY. THINK THAT CAP WILL HOLD AND MOISTURE THIN ENOUGH TO KEEP MENTION OF POPS OUT OF THE FORECAST FOR NOW. WILL HAVE TO WATCH ANOTHER FRONT THURSDAY/FRIDAY AS SHORTWAVE TROUGH MOVES ACROSS THE NORTHERN TIER OF STATES AND FLATTENS THE RIDGE. HOWEVER EXPECT FRONT TO STAY TO THE NORTH AND POPS NEAR NIL ATTM. OTHERWISE RIDGE TO DOMINATE WITH MOSTLY CLEAR SKIES AND ABOVE NORMAL TEMPS. && .PRELIMINARY POINT TEMPS/POPS...

STRONG SURFACE HEATING AND A WEAK DISTURBANCE MAY COMBINE TO PRODUCE SCATTERED THUNDERSTORMS LATE THIS AFTERNOON AND EVENING...PARTICULARLY ON THE CAPROCK. HOWEVER...THERE IS A WARM LAYER OF AIR PRESENT AROUND 8000 FEET AND THIS MAY PRECLUDE THUNDERSTORM DEVELOPMENT COMPLETELY. IF THUNDERSTORMS DO DEVELOP THE COMBINATION OF A VERY UNSTABLE AIRMASS AND A FAVORABLE VERTICAL WIND PROFILE WILL RESULT IN AT LEAST A FEW SEVERE STORMS.
