&&

.DISCUSSION...
SOUTHWESTERLY SUB-TROPICAL JET CONTINUING TO BRING PLENTY OF HIGH
CLOUDS INTO CENTRAL AND NORTHERN NM TODAY. HIGH CLOUDS WILL SHIFT EWD
THIS EVENING...AHEAD OF TWO RATHER POTENT UPPER LEVEL SHORT- WAVE
TROUGHS EXPECTED TO PHASE WITH ONE ANOTHER OVER NM WEDNESDAY. MODELS
FINALLY SEEM TO HAVE CAUGHT ONTO THE SPEED OF THESE FEATURES AND
BRING THEM EWD ACROSS WRN AND NRN NM LATE TONIGHT THROUGH
WEDNESDAY EVENING. ISSUED WINTER WEATHER ADVISORY FOR WESTERN AND
NORTHERN HIGHER TERRAIN LATE TONIGHT THROUGH WEDNESDAY EVENING.
MODELS AND NAM12 IN PARTICULAR BRING AN ORGANIZED HEAVY BAND OF
SHOWERS AND SNOW SHOWERS NWD THROUGH NWRN NM WEDNESDAY MORNING.
SCATTERED SNOW SHOWERS WILL CONTINUE ALONG AND WEST OF THE CENTRAL
MOUNTAINS THROUGH FRIDAY EVENING AND PERHAPS LONGER. LIGHT ACCUMULATIONS
POSSIBLE AREAWIDE ABOVE ABOUT 6000 FEET OR SO THROUGH WEDNESDAY
EVENING BEFORE DRIER AIR ALOFT MOVES IN LATE WEDNESDAY NIGHT. A
THIRD SHORT- WAVE TROUGH IS PROGGED TO DIVE SOUTH OF THE AREA
THURSDAY. ASSOCIATED LIFT AND MOISTURE ARE CLOSE ENOUGH...HOWEVER...COMBINE
TO PRODUCE SCATTERED SHOWERS AND SNOW SHOWERS ABOVE ABOUT 6000 FT
SOUTH OF INTERSTATE 40 THURSDAY AND THURSDAY NIGHT.

TRANSITORY UPPER LEVEL RIDGE FORECAST TO MOVE THROUGH NM SOMETIME
FRIDAY WITH THE NEXT WAVE IN THE TRAIN EXPECTED SATURDAY/SATURDAY
NIGHT. LOW CONFIDENCE...HOWEVER... REMAINS IN THE BEYOND FRIDAY AS
A VERY STRONG JET STREAM (~200KT) OVER THE CENTRAL PACIFIC OCEAN
IS RESULTING IN LARGE RUN TO RUN MODEL DIFFERENCES. FOR WHAT IT`S
WORTH...GFS AND ECMWF IN RELATIVELY GOOD AGREEMENT WITH ONE
ANOTHER EARLY NEXT WEEK. BOTH MODELS INDICATING DRY NWLY OR NLY
FLOW ALOFT THROUGH CHRISTMAS EVE. BOTH MODELS CONTINUE WITH IDEA
OF A LARGE AND DEEP UPPER LEVEL CLOSED LOW DROPPING SOUTHWARD INTO
THE GREAT BASIN AROUND CHRISTMAS DAY. STILL IN FANTASY-LAND OF THE
WEATHER PREDICTION MODEL WORLD BUT BEARS CLOSE WATCHING AS MANY
FOLKS EXPECTED TO TRAVEL BY CAR THIS CHRISTMAS HOLIDAY DUE TO THE
COMBINATION OF LOW GAS PRICES AND A FOUR DAY WEEKEND.

.FIRE WEATHER...
MOSTLY POOR VENTILATION TODAY DUE TO ABUNDANT MID AND UPPER LEVEL
CLOUDINESS...BUT SOME IMPROVEMENT IS FORECAST WEDNESDAY ACROSS
CENTRAL AND SOUTHERN PORTIONS OF THE AREA WHERE STRONGER WINDS
ASSOCIATED WITH A SHORTWAVE TROUGH WILL MOVE ACROSS. OTHERWISE...A
COMPLEX TROUGHING PATTERN HAS SET UP FOR THE REMAINDER OF THE
WORK-WEEK...WITH A TOTAL OF THREE SHORTWAVE TROUGHS FORECAST TO
IMPACT THE REGION. THE FIRST...CURRENTLY SSW OF SOCAL...WILL MOVE
ENE ACROSS NEW MEXICO WEDNESDAY BRINGING A ROUND OF WETTING
PRECIPITATION...ESPECIALLY ACROSS THE WESTERN MOUNTAINS/HIGHLANDS
AND WEST-FACING SLOPES OF THE CENTRAL MOUNTAIN CHAIN. SHORTWAVE
TROUGH NUMBER TWO...CURRENTLY OFFSHORE OF NORTHERN CALI...WILL KEEP
CHANCES FOR WETTING PRECIPITATION GOING INTO WEDNESDAY NIGHT...
ESPECIALLY OVER THE HIGHER TERRAIN AND ALONG WEST-FACING SLOPES.
THE FINAL TROUGH TO PUSH THROUGH THURSDAY NIGHT...KEEPING CHANCES
FOR WETTING PRECIPITATION GOING BUT FAVORING SOUTHERN PORTIONS OF
THE STATE.

LOW FORECASTER CONFIDENCE IN TRENDS BEYOND FRIDAY DUE TO MODEL
RUN-TO-RUN INCONSISTENCY WITH THE DEVELOPING WEEKEND TROUGH.
SATURDAY LOOKS TO BE A POOR VENTILATION DAY AND THAT COULD EXTEND
INTO SUNDAY DEPENDING ON THE DEVELOPING TROUGH. ALSO FORECASTING A
WARMING TREND FOR THE WEEKEND AND INTO EARLY NEXT WEEK...BUT AGAIN
DEPENDENT ON THE TROUGH SCENARIO. BEYOND THE WEEKEND TROUGH...THE
12Z MEDIUM RANGE MODELS SHOW NORTHWEST FLOW...WARMING TEMPS AND A
MIXED-BAG FOR VENT RATES. THE ECMWF CONTINUES TO SHOW GOOD
RUN-TO-RUN CONSISTENCY WITH A POTENTIAL MAJOR TROUGH/UPPER LOW
IMPACTING THE REGION AROUND CHRISTMAS DAY.
