AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE SAN ANGELO TX 348 PM CDT TUE APR 9 2013 .SHORT TERM... CENTER OF STRONG UPPER LOW WAS MOVING INTO NEW MEXICO AND COLORADO THIS AFTERNOON. A STRONG COLD FRONT EXTENDED FROM SOUTH OF LUBBOCK EAST TO A TRIPLE POINT...WITH A DRY LINE...NEAR KNOX CITY AT 3 PM. TCU WAS DEVELOPING IN HASKELL COUNTY JUST AHEAD OF THE FRONT. ADDED A CHANCE OF THUNDERSTORMS TO THE NORTHERN BIG COUNTRY THIS AFTERNOON. COLD FRONT POSITION WAS CLOSELY DEPICTED BY THE FASTER NAM MODEL...WHICH ITSELF IS A LITTLE SLOW. EXPECT THE FRONT TO MOVE ALONG THE INTERSTATE 20 CORRIDOR 9 PM TO 10 PM...A SAN ANGELO TO BROWNWOOD LINE AROUND 11 PM...AND JUNCTION 2 AM TO 3 AM. MOST STORMS WILL BE ALONG OR ELEVATED BEHIND THE FRONT. WITH RAP SBCAPES OF 2500 J/KG AND STRONG 0-3 KM HELICITIES OVER 500 M2/S2...COULD SEE SOME SEVERE THUNDERSTORMS. THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ALONG AND EAST OF A HASKELL... ABILENE...SAN ANGELO...JUNCTION LINE TONIGHT. MAIN THREATS WILL BE LARGE HAIL AND DAMAGING WINDS. COULD SEE SEE AN ISOLATED TORNADO ALONG THE FRONT...BUT TORNADO THREAT MAY BE MINIMAL IF MOST STORMS BECOME ELEVATED BEHIND THE FRONT. STRONG NORTH WINDS OF 20 TO 30 MPH CAN BE EXPECTED BEHIND THE FRONT...WITH A FEW GUSTS TO 40 MPH. GOING AROUND 10 DEGREES LOWER THAN GFS MOS GUIDANCE BEHIND THE FRONT OVERNIGHT AND ON WEDNESDAY...AND THAT MAY STILL BE A COUPLE DEGREES TOO WARM. 04 .LONG TERM... THE LATTER HALF OF THE WORK WEEK WILL REMAIN RATHER QUIET ACROSS WEST CENTRAL TX. WE WILL SEE LARGE SCALE SUBSIDENCE IN THE WAKE OF THE DEPARTING TROUGH RESULTING IN CLEARING SKIES WEDNESDAY NIGHT. THE PRESENCE OF DRY AIR AND CLEAR SKIES WILL PROMOTE STRONG RADIATIONAL COOLING. HOWEVER...WIND SPEEDS WILL REMAIN IN THE 5-10 MPH RANGE THROUGH MOST OF THE OVERNIGHT PERIOD. THIS WILL LIMIT THE AREA AFFECTED BY FREEZING TEMPS ON THURSDAY MORNING BY KEEPING THE BOUNDARY LAYER AT LEAST PARTIALLY MIXED. THAT SAID...A FEW AREAS /ESPECIALLY LOW LYING AREAS AND RIVER VALLEYS/ WILL LIKELY SEE A BRIEF...LIGHT FREEZE. A SPECIAL WEATHER STATEMENT WILL BE ISSUED TO HIGHLIGHT THIS POTENTIAL. WARMER TEMPERATURES ARE EXPECTED THURSDAY AND FRIDAY AS SOUTH WINDS RETURN AND WE RECEIVE A GOOD AMOUNT OF INSOLATION. TEMPS WILL STILL BE BELOW NORMAL THURSDAY WITH HIGHS IN THE MID 60S TO LOWER 70S BUT BY FRIDAY TEMPS WILL BE PUSHING 80 DEGREES. THE MODELS CONTINUE TO PICK UP ON A WEAK SHORTWAVE TROUGH TRAVERSING THE AREA ON FRIDAY. THIS WOULD ALLOW A WEAK COLD FRONT TO SAG SOUTH INTO NORTH TX BUT THIS BOUNDARY IS EXPECTED TO STALL NORTH OF I-20. THE PRIMARY EFFECT WOULD BE SURFACE WINDS BACKING TO A MORE EASTERLY DIRECTION. A SECOND WAVE /DETACHED FROM THE NORTHERN STREAM/ IS PROGGED TO MOVE SOUTHEAST ACROSS CA BEFORE TURNING EAST AND MOVING ACROSS NORTHERN MEXICO INTO DEEP SOUTH TX. THERE REMAINS SOME SLIGHT TIMING DIFFERENCES IN HOW THE MODELS HANDLE THIS FEATURE BUT THE CONSENSUS IS THAT THIS FEATURE WILL PASS TOO FAR SOUTH OF WEST CENTRAL TX TO BRING APPRECIABLE RAIN CHANCES. THE GEM IS THE OUTLIER AT THIS POINT AND HAS BEEN DISREGARDED. THE INCREASE IN CLOUD COVER AND WEAKENING OF THE LOWER TROPOSPHERIC THERMAL RIDGE SHOULD KEEP TEMPS IN THE UPPER 70S TO NEAR 80 DEGREES ON SATURDAY. BY SUNDAY...HOWEVER...WE WILL SEE THE LOW LEVEL THERMAL RIDGE INTENSIFY MARKEDLY...WITH H85 TEMPS PROGGED TO INCREASE TO 20-22C. IN ADDITION...WINDS ARE FORECAST TO VEER TO THE SOUTHWEST WITH THE DRYLINE PROPAGATING INTO THE EASTERN COUNTIES. THE LARGER BOWEN RATIO AND ENHANCED DOWNSLOPE WINDS WILL SUPPORT MUCH WARMER TEMPS... POTENTIALLY APPROACHING 90 DEGREES. THIS PATTERN WILL CONTINUE INTO THE EARLY PART OF NEXT WEEK WITH WELL ABOVE NORMAL TEMPS AND GENERALLY DRY WEATHER. JOHNSON && .PRELIMINARY POINT TEMPS/POPS...
