AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
920 AM PST THU DEC 24 2015

.SYNOPSIS...SOUTHWEST TO WEST WINDS WILL INCREASE TODAY AHEAD OF A
COLD STORM SYSTEM. THIS STORM WILL PRESS ACROSS THE AREA TONIGHT
INTO CHRISTMAS DAY WITH A BAND OF HIT AND MISS SHOWERS. SNOW MAY
FALL AS LOW AS 2500 TO 3000 FEET IN SOME AREAS. GUSTY NORTH WINDS
WILL DEVELOP CHRISTMAS NIGHT AND LAST THROUGH THE WEEKEND
ACCOMPANIED BY MUCH COLDER WEATHER. MAINLY DRY CONDITIONS ALONG WITH
A MODERATING TREND ARE EXPECTED FOR THE CLOSE OF THE YEAR.
&&

.UPDATE...FAIRLY QUIET WEATHER ACROSS THE REGION THIS MORNING AHEAD
OF A COLD STORM SYSTEM THAT WILL IMPACT THE REGION OVER THE NEXT
COUPLE OF DAYS. SOUTHWEST TO WEST WINDS ARE EXPECTED TO INCREASE
DURING THE AFTERNOON AND PRECIPITATION WILL GRADUALLY START PUSHING
INTO THE NORTHERN ZONES BY LATE AFTERNOON. FEEL THAT THE HIGH WIND
WARNING FOR THE SIERRA SLOPES AND WESTERN MOJAVE DESERT MAY BE A BIT
OVERDONE...BUT AT THIS TIME WILL NOT MAKE ANY CHANGES AND WILL WAIT
AND SEE HOW THINGS PROGRESS. IT SHOULD GET WINDY IN THOSE
LOCATIONS THOUGH. NO UPDATES AT THIS TIME.
&&

PREV DISCUSSION
315 AM PST THU DEC 24 2015

.SHORT TERM...CHRISTMAS EVE DAY THROUGH CHRISTMAS NIGHT.

WE ARE IN FOR A SACK OF METEOROLOGICAL GOODIES TODAY THROUGH
CHRISTMAS DAY COURTESY OF THE SANTA STORM. PRESENTLY, THERE ARE SOME
BATCHES OF HIGHER LEVEL CLOUDS, ESPECIALLY ACROSS SAN BERNARDINO AND
SOUTHERN MOHAVE COUNTIES, COURTESY OF MOUNTAIN WAVE ACTIVITY OFF THE
TEHACHAPIS. THERE ARE ALSO SOME MID-LEVEL CLOUDS ACROSS SOUTHERN
PARTS OF NYE AND LINCOLN COUNTIES AND MUCH OF CLARK COUNTY AND THE
ARIZONA STRIP. THE MID-LEVEL CLOUDS SHOULD ERODE AFTER DAYBREAK AND
THE THOUGHT IS IN THESE AREAS WE SHOULD SEE A GOOD AMOUNT OF SUN FOR
WINDOW THIS AFTERNOON.

WINDS WILL START TO PICK UP TODAY AHEAD OF A STORM THAT WILL CAUSE
SANTA AND HIS TEAM OF REINDEER SOME ISSUES. A 120 KT+ JET AT 250 MB
MOVES OVER THE AREA TODAY AND AS THESE WINDS GET MIXED DOWN TO THE
SURFACE, THEY WILL CREATE GUSTY WINDS. I ISSUED WIND HEADLINES TO
ADDRESS THIS IN THE WESTERN PART OF THE AREA. FOR THE EASTERN SIERRA
AND OWENS VALLEY, THE ARW MODEL SHOWS A CRITICAL LAYER DEVELOPING TO
THE LEE OF THE SOUTHERN SIERRA THIS EVENING. GIVEN CROSS BARRIER
FLOW, WE SHOULD SEE DOWNSLOPE WINDS DEVELOP AND THESE LOOK TO AT
LEAST MAKE IT INTO THE WESTERN PARTS OF THE OWENS VALLEY SO A HIGH
WIND WARNING WAS ISSUED. NORTHWEST SAN BERNARDINO COUNTY SHOULD SEE
POCKETS OF WARNING LEVEL WINDS THOUGH MANY SPOTS MAY JUST END UP
WITH ADVISORY LEVEL GUSTS (BELOW 58 MPH) BUT I DECIDED TO ISSUE A
HIGH WIND WARNING AS SOME FAVORED SPOTS LIKE FORT IRWIN COULD BLOW
WELL. OTHERWISE, WIND ADVISORIES WERE ISSUED FOR THE REST OF INYO
COUNTY, NORTHEAST SAN BERNARDINO COUNTY, THE MORONGO BASIN AND
SOUTHERN CLARK COUNTY. THE MORONGO BASIN ADVISORY RUNS LONGER AS
THEY TYPICALLY GET A DELAY WITH THEIR WINDOW OF STRONGEST WINDS,
WHICH IS TYPICALLY FROM THE WEST TO NORTHWEST THAT WILL HOLD OFF
UNTIL LATER CHRISTMAS MORNING. WINDS WILL DROP OFF FOR A BIT IN ALL
AREAS ONCE THE COLD FRONT PASSES THROUGH.

THE SANTA STORM WILL ALSO BRING A BAND OF SHOWERS WITH IT AS THE
COLD FRONT WORKS ON SOUTH. THE NORTHWEST TRAJECTORY WILL NOT BODE
WELL FOR MOISTURE BUT HAS GOOD FORCING. HOWEVER, EXCEPT FOR LINCOLN
COUNTY AND NORTHERN MOHAVE COUNTY, WHATEVER SHOWERS THERE ARE WILL
BE A QUICK SHOT OF 1-3 HOURS AT BEST. A BETTER DEVELOPED BAND OF
SHOWERS SHOULD IMPACT LINCOLN COUNTY OWING TO STRONG FORCING AND
UPLIFT FROM THE TERRAIN AND THUS A WINTER WEATHER ADVISORY REMAINS
IN EFFECT THERE. IN ADDITION, A WINTER WEATHER ADVISORY REMAINS
IN EFFECT FOR NORTHERN MOHAVE COUNTY. 700 MB TEMPS TANK TO
-12C WITH THE FRONT WHICH WILL DROP SNOW LEVELS TO 2500-3000 FEET.
THIS WILL CHANGE RAIN QUICKLY TO SNOW AND WE MAY EVEN SEE A LITTLE
SNOW IF WE ARE LUCKY ON THE FAR WEST SIDE OF THE LAS VEGAS VALLEY
CHRISTMAS MORNING. POST-FRONTAL ENERGY AND LINGERING MID-LEVEL
MOISTURE COULD STILL RESULT IN A FEW SHOWERS IN THE AFTERNOON ON
CHRISTMAS DAY.

FOR TEMPS, I LEANED TOWARD THE WARMER ECMWF AS IT SEEMS TO BE DOING
BETTER LATELY FOR HIGHS. LOWS MAY NOT GET SO CHILLY AS GUIDANCE
SHOWS TONIGHT GIVEN THE WIND STAYS UP AND I WENT WITH THE WARMER
GUIDANCE IN SOME SPOTS TONIGHT. MUCH COLDER AIR ARRIVES BEHIND THE
SANTA STORM AND MANY LOWER DESERT VALLEYS WILL DROP INTO THE 20S
CHRISTMAS NIGHT.

.LONG TERM...SATURDAY THROUGH WEDNESDAY.

SATURDAY STILL LOOKS QUITE BLUSTERY DUE TO BELOW NORMAL TEMPERATURES
AND GUSTY NORTH WINDS. IN HOUSE MODELS STILL PAINTING STRONGEST
NORTH WINDS WILL BE DOWN THE COLORADO RIVER VALLEY AND EASTERN SAN
BERNARDINO COUNTY. SOME OF THE HIGHER TERRAIN IN SOUTHERN LINCOLN,
CLARK AND INYO COUNTIES WILL ALSO LIKELY BE VERY WINDY. DECISION FOR
WIND PRODUCT TYPES IS NEARING.

WINDS SHOULD SLOWLY ABATE THROUGH SUNDAY AS GRADIENTS RELAX AS UPPER
LOW SHIFTS EAST INTO THE BIG BEND REGION OF TEXAS. LITTLE RECOVERY
IN TEMPERATURES EXPECTED SUNDAY AS EVERYONE HEADS BACK HOME AFTER
THE LONG HOLIDAY WEEKEND.

MODELS STARTING TO COME INTO BETTER AGREEMENT NEXT WEEK. THE
PROGRESSIVE PATTERN WILL PERSIST WITH OUR NEXT TROUGH PASSAGE ON
MONDAY/TUESDAY. ONLY MENTIONABLE POPS FOR NOW IS ALONG THE EASTERN
SIERRA SLOPES OF INYO COUNTY. MODELS DROP A WEAKER TROUGH SOUTHEAST
ACROSS THE GREAT BASIN ON WEDNESDAY OR THURSDAY. TEMPERATURES WILL
MODERATE SLOWLY UNDER CONTINUAL TROFINESS ALONG WITH SEEING MORE
CLOUD COVER AT TIMES.
&&

.AVIATION...FOR MCCARRAN...WINDS WILL REMAIN LIGHT TODAY WITH A
RIBBON OF MOISTURE AROUND 6-10KFT DIFFUSING BY THE
AFTERNOON...ALLOWING MORE SUNSHINE. THIS SHOULD AID IN THE
DEVELOPMENT OF SOUTHWEST WINDS...BECOMING GUSTY BY LATE AFTERNOON.
SOUTHWEST WINDS WILL GRADUALLY VEER TO MORE WESTERLY AND LOSE THEIR
GUSTINESS DURING THE OVERNIGHT HOURS. MOISTURE WILL ALSO BE ON THE
INCREASE WITH ADDITIONAL LOWER CLOUDS AND PRECIPITATION CHANCES
AFTER MIDNIGHT.

FOR THE REST OF SOUTHERN NEVADA...NORTHWEST ARIZONA...AND SOUTHEAST
CALIFORNIA...HARD TO LUMP TERMINAL SITES ACROSS THE REGION INTO ONE
GROUP FOR THE PERIOD. KBIH IS PROVING TO BE A DIFFICULT FORECAST.
HIGH RESOLUTION GUIDANCE SUGGESTS LIGHTER WEST TO SOUTH WINDS
THROUGH TODAY WITH ANY PRECIPITATION REMAINING NEAR THE CREST. LAMP
GUIDANCE BLASTS NORTHERLY WINDS IN AND BRINGS SNOW SHOWERS
IN...POSSIBLY STARTING AS RAIN. ONLY MADE TWEAKS TO GOING TAF. KDAG
WILL REMAIN WESTERLY WHILE THE REST OF THE AREA SHOULD BEGIN TO SEE
SOME FORM OF SOUTHWEST WINDS. A BAND OF MOISTURE ALONG WITH COLD
FRONT WILL SINK SOUTH ACROSS THE SOUTHERN GREAT BASIN THIS
EVENING...PRODUCING LOCALLY LOWER CIGS AS WELL AS AT LEAST MOUNTAIN
SHOWERS.
&&

.SPOTTER INFORMATION STATEMENT...SPOTTER REPORTS OF WIND GUSTS OR
WIND DAMAGE AS WELL AS ANY BLOWING DUST ARE REQUESTED THIS AFTERNOON
INTO CHRISTMAS DAY. SPOTTER REPORTS OF SNOW AMOUNTS ARE WELCOME
TONIGHT INTO CHRISTMAS DAY. ADDITIONAL SPOTTER REPORTS FOR WIND MAY
BE NEEDED OVER THE WEEKEND ESPECIALLY ON SATURDAY.
