AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
829 AM PST THU DEC 5 2013

.SYNOPSIS...COLD CONDITIONS WILL CONTINUE THROUGH FRIDAY WITH
ANOTHER ROUND OF SUBFREEZING TEMPERATURES EXPECTED TONIGHT INTO
FRIDAY MORNING. A STORM SYSTEM MOVING IN FROM THE NORTH COULD BRING
LOW ELEVATION SNOW TO PORTIONS OF THE MOJAVE DESERT ON SATURDAY. DRY
AND COLD WEATHER WILL FOLLOW EARLY NEXT WEEK.
&&

.UPDATE...SATELLITE LOOP SHOWED CLOUDS OVER SAN BERNARDINO COUNTY
SLOWLY ERODING FROM THE OUTSIDE IN...WHILE A SOLID DECK OF LOW
CLOUDS REMAINED ENTRENCHED OVER THE SNOW FIELD IN ESMERALDA COUNTY.
TWEAKED SKY GRIDS FOR THE MORNING TO FIT SATELLITE TRENDS AND ALSO
MADE A MINOR ADJUSTMENT FOR THE EXPECTED AFTERNOON TRENDS. NO OTHER
CHANGES AT THIS TIME.
&&

.PREV DISCUSSION...
257 AM PST THU DEC 5 2013

.SHORT TERM...NORTHERLY ARCTIC FLOW CONTINUES TO POUR INTO THE
REGION THROUGH FRIDAY MAINTAINING COLD CONDITIONS. THERE IS GOOD
MODEL GUIDANCE AGREEMENT WITH HIGH TEMPERATURES TODAY AND FRIDAY
STAYING WELL BELOW NORMAL BY 15 OR MORE DEGREES. THIS EQUATES TO
TEMPERATURES STRUGGLING TO REACH 40 DEGREES IN THE LAS VEGAS VALLEY.
THE LOW MAX RECORD FOR TODAY AND FRIDAY IS 42 AND 41 DEGREES
RESPECTFULLY AND EITHER RECORD COULD BE IN JEOPARDY OF FALLING...
ESPECIALLY THE ONE FOR TODAY. LOWS FRIDAY MORNING SHOULD AGAIN DIP
TO WELL BELOW FREEZING AND THE HARD FREEZE WARNING LOOKS GOOD. ITS A
HARDER CALL FOR SATURDAY WHEN MODEL GUIDANCE SHOWS A REBOUND IN LOW
TEMPERATURES TO AROUND OR JUST ABOVE FREEZING FOR LAS VEGAS.
REGARDLESS...MANY LOCATIONS THROUGHOUT THE AREA INCLUDING THE OUTER
EDGES OF THE LAS VEGAS VALLEY COULD SEE A CONTINUATION OF FREEZING
CONDITIONS SATURDAY MORNING.

LATE FRIDAY INTO EARLY SATURDAY MORNING...MODELS BRING THE NEXT
SHORTWAVE TO THE AREA. THIS COULD BRING ENHANCED HIGH ELEVATION
WINDS TO THE SIERRA FOLLOWED BY INCREASING MOISTURE AND AN
INCREASING CHANCE OF SNOW OVERNIGHT FRIDAY.

.LONG TERM...SATURDAY THROUGH WEDNESDAY...THE NEXT TROUGH IS STILL
ON TRACK TO IMPACT THE FORECAST AREA SATURDAY. THE TROUGH AXIS GETS
INTO WESTERN NEVADA DURING THE MORNING HOURS WITH PRECIPITATION
SPREADING ACROSS MAINLY THE NORTHERN AND WESTERN PORTIONS OF THE
FORECAST AREA. LATEST MODEL RUNS APPEAR TO BE A BIT SLOWER WITH THE
PROGRESSION OF THE TROUGH SO I LOWERED POPS IN THE SOUTHEAST PART OF
THE FORECAST AREA FOR THE MORNING. THE TROUGH CONTINUES TO MOVE
ACROSS NEVADA DURING THE AFTERNOON WITH AT LEAST A CHANCE OF RAIN
AND SNOW ACROSS THE ENTIRE FORECAST AREA. THE BEST CHANCE OF
SIGNIFICANT PRECIPITATION INITIALLY WILL BE THE SIERRA SATURDAY
MORNING...THEN ACROSS MOHAVE COUNTY AND THE MOUNTAINS OF SOUTHEAST
NEVADA BY THE AFTERNOON WITH SOME PRETTY DECENT FORCING INDICATED BY
THE MODELS. MODELS INDICATE PRECIPITATION TAPERING OFF QUICKLY IN
THE WEST SATURDAY AFTERNOON. STILL NOT REAL CONFIDENT IN SNOWFALL
AMOUNTS AS THE MODELS DIFFER IN PLACEMENT AND AMOUNT OF QPF. SNOW
LEVELS WILL LOWER TO MANY VALLEY FLOORS SATURDAY BUT JUST HOW LOW
ACCUMULATING SNOW WILL OCCUR REMAINS UNCERTAIN. THE MODEL SOUNDINGS
SHOW VARYING WET BULB ZERO LEVELS IN LAS VEGAS...VARYING FROM ABOUT
2800 FEET ON THE ECMWF ALL THE WAY UP TO ABOUT 4000 FEET ON THE GFS.
I LEANED MORE TOWARD THE ECMWF FOR SNOW LEVELS SO PRECIPITATION IN
THE LAS VEGAS VALLEY SATURDAY SHOULD BE IN THE FORM OF SNOW FOR THE
HIGHER PARTS OF THE VALLEY. PRECIPITATION CHANCES SHOULD END FAIRLY
QUICKLY FROM WEST TO EAST SATURDAY EVENING AS THE TROUGH AXIS SHIFTS
INTO UTAH AND ARIZONA. MOHAVE COUNTY WILL STILL SEE A CHANCE OF
DECENT RAIN AND SNOW THROUGH SATURDAY EVENING BUT IT SHOULD BE DONE
EVERYWHERE BY MIDNIGHT OR SO. THEN WE WILL BE UNDER A CHILLY
NORTH/NORTHWEST FLOW SUNDAY THROUGH TUESDAY WITH TEMPERATURES WELL
BELOW NORMAL AND THE POSSIBILITY OF MORE HARD FREEZE WARNINGS.
MODELS GENERALLY SHOW RISING HEIGHTS AND MODERATING TEMPERATURES FOR
WEDNESDAY AND CONTINUED DRY CONDITIONS.

.AVIATION...FOR MCCARRAN...GENERALLY LIGHT NORTHEAST WINDS 6-8KTS TO
CONTINUE OTHERWISE...COLD WEATHER WITH NO OPERATIONALLY SIGNIFICANT
CLOUDS OR WINDS CAN BE EXPECTED THROUGH FRIDAY. THERE WILL BE A
CHANCE OF RAIN AND SNOW ON SATURDAY WHICH COULD RESULT IN LOW
CEILINGS.

FOR THE REST OF SOUTHERN NEVADA...NORTHWEST ARIZONA...AND SOUTHEAST
CALIFORNIA...COLD WEATHER WITH NO OPERATIONALLY SIGNIFICANT CLOUDS
OR WINDS CAN BE EXPECTED TODAY AND FRIDAY...THEN A STORM SYSTEM
WILL BRING A CHANCE OF RAIN AND LOW ELEVATION SNOW ON SATURDAY WHICH
COULD RESULT IN A PERIOD OF LOW CEILINGS.
