AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE SAN ANGELO TX 601 PM CST FRI DEC 23 2011 .DISCUSSION... SEE 00Z AVIATION DISCUSSION BELOW. && .AVIATION... MVFR CEILINGS PREVAIL ACROSS THE TERMINALS EARLY THIS EVENING. AN UPPER LEVEL STORM SYSTEM WILL AFFECT THE AREA LATE TONIGHT THROUGH SATURDAY WITH DETERIORATING CONDITIONS EXPECTED ACROSS THE TERMINALS TOWARDS DAYBREAK SATURDAY. LIGHT SNOW IS EXPECTED TO DEVELOP ACROSS THE KSJT...KABI AND KSOA TERMINALS AFTER 08Z...WITH A COMBINATION OF LIGHT RAIN AND SNOW ACROSS THE REMAINING TERMINALS BY 12Z. IFR CONDITIONS APPEAR LIKELY AT ALL TERMINALS ON SATURDAY...WITH LOCALIZED AREAS OF LIFR ACROSS MAINLY THE KSJT AND KSOA TERMINALS SATURDAY MORNING IN POCKETS OF HEAVIER SNOWFALL. WINDS WILL BE LIGHT NORTH/NORTHEAST 10 KT OR LESS THROUGH THE PERIOD. && .PREV DISCUSSION... /ISSUED 400 PM CST FRI DEC 23 2011/ SHORT TERM... UNCERTAINTY REMAINS A MAJOR CONCERN THIS FORECAST CYCLE. THE LATEST SURFACE DATA INDICATE SNOW IS CONTINUING IN SOUTHEASTERN NEW MEXICO AND FAR WEST TEXAS. LATEST SATELLITE IMAGERY INDICATES THE UPPER-LEVEL LOW IS ON TRACK AS COMPARED TO THE MODELS. I BELIEVE...BASED ON THE LATEST MODEL DATA...WE WILL SEE SNOW ACROSS MAINLY OUR WESTERN COUNTIES DURING THE NEXT 24 HOURS. THE BIG QUESTIONS ARE WHEN WILL THE SNOW BEGIN AND HOW MUCH SNOW WILL ACCUMULATE. FOR NOW...I DECIDED TO CONTINUE WITH POPS FROM OUR PREVIOUS PACKAGE FOR TONIGHT AND TOMORROW. I DECIDED...GIVEN THE UNCERTAINTY...TO CONTINUE WITH WEATHER GRIDS FOR TONIGHT AS WE PREVIOUSLY HAD THEM. I DID ADD AN ALL SNOW AREA TO OUR WEATHER GRIDS FOR TOMORROW AFTERNOON FOR SOME OF OUR WESTERN COUNTIES...SPECIFICALLY FOR FISHER...NOLAN...STERLING...AND IRION. ELSEWHERE TOMORROW AFTERNOON...RAIN AND SNOW MIX WEATHER GRIDS SILL LOOK BEST. SNOW ACCUMULATIONS OF 1 TO 3 INCHES STILL LOOK REASONABLE FOR LOCATIONS MAINLY ALONG AND NORTH OR WEST OF A LINE FROM OZONA...TO SAN ANGELO...TO ABILENE...TO THE HASKELL AND THROCKMORTON COUNTY BORDER. WE WILL CONTINUE OUR SPECIAL WEATHER STATEMENT. HOWEVER...I BELIEVE THE UNCERTAINTY JUST DOES NOT WARRANT A WINTER WEATHER ADVISORY AT THIS TIME. IN ADDITION...MAINLY CHANCE POPS ACROSS OUR COUNTIES CONTINUE TO LOOK GOOD FOR TONIGHT AND TOMORROW...ESPECIALLY FOR THE AREAS WHERE I THINK WE WILL SEE SOME SNOW...RATHER THAN INCREASING SOME AREAS INTO THE LIKELY RANGE. AS FOR TEMPERATURES...I DID NOT MAKE ANY BIG CHANGES FOR LOWS TONIGHT AND HIGHS TOMORROW...ONLY MINOR ADJUSTMENTS HERE AND THERE. HUBER LONG TERM... THE 12Z GFS AND NAM LOOK TO BE IN BETTER AGREEMENT WITH THE FORECAST TRACK OF THE UPPER LOW SATURDAY NIGHT AND SUNDAY.... WITH THE NAM COMPARATIVELY A LITTLE FARTHER SOUTH. THE UPPER LOW IS PROGGED TO BE NEAR WINK TX BY SATURDAY EVENING...THEN TRACK SLOWLY TO THE NORTHEAST AND BE JUST NORTH OF JAYTON BY 12Z SUNDAY. INDICATIONS ARE FOR THIS UPPER LOW TO MEANDER OVER NORTHWESTERN TEXAS ON CHRISTMAS DAY...AND THEN TO BEGING LIFTING NORTHEAST INTO OKLAHOMA LATER SUNDAY NIGHT. BASED THE FORECAST LARGELY ON THE 12Z NAM...BUT HAVE NOTICED WHERE THE 18Z NAM LOOKS DRIER FOR SATURDAY EVENING AND SATURDAY NIGHT. DO EXPECT THE PRECIPITATION TO END FROM WEST TO EAST SATURDAY NIGHT...AS MID-LEVEL DRY SLOT OVERTAKES OUR AREA. STILL HAVE UNCERTAINTY ON PRECIP TYPE. CARRYING 20-50 POPS FOR RAIN/SNOW MIX ACROSS OUR WESTERN AND CENTRAL COUNTIES WITH JUST A LIGHT SNOW MENTION ACROSS OUR NORTHWESTERN COUNTIES. ACROSS OUR FAR EAST AND SOUTHEAST COUNTIES...HAVE LIKELY POPS FOR RAIN BEFORE MIDNIGHT. IF PRECIPITATION CONTINUES AFTER MIDNIGHT AND MID-LEVEL DRY SLOT IS SLOWER TO ARRIVE...COLUMN ALOFT WOULD BECOME MORE SUPPORTIVE OF A RAIN/SNOW MIX OR PERHAPS ALL SNOW IN OUR FAR EASTERN COUNTIES. EXPECT A DRY CHRISTMAS DAY...WRAP AROUND MOISTURE WITH THE SYSTEM SHOULD RESULT IN CONSIDERABLE LOW CLOUDINESS. TEMPERATURES WILL NOT BE AS COLD SUNDAY AS ON SATUDAY...BUT ARE STILL NOT EXPECTED TO GET OUT OF THE 40S ACROSS OUR AREA. AS THE UPPER LOW PULLS AWAY ACROSS OKLAHOMA ON MONDAY...DRIER AIR AIR INFILTRATION WILL RESULT IN DECREASING CLOUD COVER FOR WEST CENTRAL TEXAS. MODELS CONTINUE TO INDICATE A WARMING TREND NEXT WEEK WITH A DRY PATTERN...WITH BROAD WEST TO NORTHWEST FLOW ALOFT. CLEAR TO PARTLY CLOUDY SKIES AND DRY AIRMASSES TO RESULT IN LARGER DAILY DIURNAL TEMPERATURE RANGES FOR OUR AREA. 19 && .PRELIMINARY POINT TEMPS/POPS...
