Area forecast discussion, Jan 1, 10:00 AM PST, 5 hours 11 minutes before
AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
1000 AM PST SAT JAN 1 2011
.SYNOPSIS...WELL BELOW NORMAL TEMPERATURES WILL CONTINUE THROUGH THE
WEEKEND AS A STORM DROPS DOWN THE CALIFORNIA COAST. PRECIPITATION
CHANCES WILL BEGIN IN THE SIERRA TODAY...AND SPREAD ACROSS THE
MOJAVE DESERT AND SOUTHERN GREAT BASIN SUNDAY AND MONDAY. SOME LOW
ELEVATION SNOW IS POSSIBLE WITH THIS STORM.
&&
.UPDATE...SATELLITE LOOPS SHOWED MOSTLY CLEAR SKIES ACROSS THE
SOUTHERN HALF OF THE FORECAST AREA AND NOT MUCH UPSTREAM MOISTURE
MOVING IN UNTIL THIS EVENING. THE FORECAST WAS UPDATED TO REFLECT
THIS.
AS FAR AS THE PACIFIC SYSTEM MOVING INTO SOUTHERN CALIFORNIA
SUNDAY...THE 12Z GFS AND NAM ARE NOW IN FAIRLY GOOD AGREEMENT WITH
THE TRACK OF THE SYSTEM THROUGH MONDAY AFTERNOON. BOTH KEEP IT LESS
PROGRESSIVE AND SLOWLY SLIDE THE UPPER LEVEL CENTER SOUTHEAST FROM
THE CENTRAL COAST TO NEAR BAKERSFIELD BETWEEN SUNDAY AND MONDAY. THE
GFS DEPICTS MORE QPF THAN THE NAM ACROSS THE SAN BERNARDINO COUNTY
DESERTS AND SOUTHERN NEVADA SUNDAY NIGHT AND MONDAY. WILL WAIT TO
SEE THE 12Z ECMWF BEFORE MAKING ANY SIGNIFICANT CHANGES...BUT
INITIAL INCLINATION IS TO INCREASE POPS AND QPF FOR THE SOUTHERN
HALF OF THE AREA SUNDAY NIGHT AND MONDAY.
&&
.AVIATION...FOR MCCARRAN...WINDS WILL REMAIN LIGHT THROUGH TODAY BUT
COULD SHOW AN EASTERLY COMPONENT BY LATE MORNING INTO THE AFTERNOON.
A GENEROUS AMOUNT OF HIGH CLOUDS ARE MOVING ACROSS THE AREA
CURRENTLY BUT THERE COULD BE A BREAK AROUND 12Z BETWEEN THIS LAYER
AND THE NEXT MID TO HIGH LEVEL LAYER FORECAST FOR MID MORNING. NO
PRECIPITATION IS EXPECTED TODAY OR TONIGHT.
FOR THE REST OF SOUTHERN NEVADA...NORTHWEST ARIZONA...AND SOUTHEAST
CALIFORNIA...LIGHT AND VARIABLE WINDS ARE EXPECTED IN MOST AREAS
TODAY. ABUNDANT HIGH CLOUDS THIS MORNING CENTRAL AND EAST WITH
INCREASING MID TO HIGH LEVEL CLOUDS MOVING IN FROM THE NORTHWEST
THROUGH THE DAY. SNOW SHOWERS ARE EXPECTED TO DEVELOP OVER THE
SIERRA BY MID TO LATE MORNING WITH MOUNTAIN TOPS BECOMING OBSCURED.
THE NEXT BEST CHANCE OF SHOWERS WILL BE SUNDAY THROUGH MONDAY WITH
THE BETTER CHANCES OVER THE WESTERN CWA.
&&
.PREV DISCUSSION...
248 AM PST SAT JAN 1 2011
.SHORT TERM...NEW YEAR BUT SAME FORECASTING WOES. PLENTY OF
UNCERTAINTY REMAINS REGARDING THE EVOLUTION OF THE STORM WHICH WAS
NEAR 43N 134W EARLY THIS MORNING. THE MAIN PROBLEM APPEARS TO BE IN
THE HANDLING OF SHORTWAVE ENERGY NEAR 43N 159W EARLY THIS MORNING.
THIS ENERGY IS FORECAST TO SPLIT...WITH ONE PIECE STAYING IN THE
NORTHERN STREAM AND HEADING FOR BRITISH COLUMBIA AND THE OTHER PIECE
DIGGING INTO THE BACK SIDE OF THE MAIN STORM. THE QUESTION IS WHICH
STREAM RECEIVES MOST OF THE ENERGY...WHICH MAKES A VERY SMALL
DIFFERENCE IN THE TRACK AND TIMING OF THE STORM FROM A GLOBAL
PERSPECTIVE...BUT THIS VERY SMALL DIFFERENCE WOULD MAKE A HUGE
DIFFERENCE IN THE SENSIBLE WEATHER AND IMPACTS FOR OUR AREA. IF THE
MAJORITY OF THE ENERGY GOES TO THE NORTHERN STREAM...AS PER THE 00Z
ECMWF...PRECIP CHANCES WILL SPREAD ACROSS THE MOJAVE DESERT ABOUT 12
HOURS LATER THAN IF THE MAJORITY OF THE ENERGY GOES TO THE SOUTHERN
STREAM...AS PER THE 00Z GFS. THE ECMWF SOLUTION SUGGESTS ALL RAIN
ACROSS THE LOWER DESERTS MONDAY...WHILE THE GFS SOLUTION SUGGESTS
PRECIP WOULD START AS SNOW SUNDAY NIGHT/EARLY MONDAY MORNING BEFORE
CHANGING TO RAIN DURING THE DAY MONDAY. THE MODEL DIFFERENCES HAVE
BEEN A PROBLEM WITH THIS SYSTEM FOR SEVERAL DAYS. WITH SUCH
UNCERTAINTY...FELT THE BEST COURSE OF ACTION WAS TO MENTION SNOW
OVER THE LOWER DESERTS...BUT ASSIGN IT A LOW PROBABILITY /SLIGHT
CHANCE TO LOW END CHANCE/. EVEN IF THE 00Z GFS VERIFIES...BELIEVE
THAT ANY SNOW ACCUMULATION WOULD BE LIMITED TO LIGHT AMOUNTS ON
EXPOSED SURFACES OR GRASSY AREAS EARLY MONDAY MORNING...WHICH WOULD
MELT AWAY DURING THE DAY AS WARM ADVECTION CHANGES THE PRECIP OVER
TO RAIN. IT MUST BE EMPHASIZED THAT THIS IS ONLY ONE POSSIBLE
OUTCOME...AND IF THE 00Z ECMWF VERIFIES...ANY PRECIP WOULD LIKELY BE
ALL RAIN. ONE THING WHICH IS REASONABLY CERTAIN WITH THIS STORM IS
ANOTHER ROUND OF SIGNIFICANT SNOW IN THE SIERRA. THE UNCERTAINTY
MENTIONED ABOVE WOULD MAKE QUITE A DIFFERENCE IN THE SNOW
AMOUNTS...SO EVEN THOUGH IT IS LESS THAN 24 HOURS UNTIL THE ONSET OF
THE EVENT...HOISTED A WINTER STORM WATCH FOR THE SIERRA ZONE.
.LONG TERM...TUESDAY THROUGH FRIDAY...MODEL DIFFICULTIES CONTINUE
WITH THE 00Z RUNS. AN AREA OF LOW PRESSURE IS FORECAST TO SLIDE DOWN
ALONG THE WEST COAST TUESDAY AND WEDNESDAY AND THEN POSSIBLY SWING
EASTWARD ALONG THE U.S. AND MEXICO BORDER THURSDAY AND FRIDAY. THIS
BEST FITS THE ECMWF AND GEM SOLUTION. THE GFS AND ITS ENSEMBLE MEAN
AND CLUSTER OF SOLUTIONS FAVORS A MORE ELONGATED TROUGH SOLUTION
WITH THE LOW CENTER ORIGINALLY NEAR THE SOUTHERN CALIFORNIA COAST
TUESDAY BEFORE RETROGRADING TO THE SOUTHWEST AND SETTING UP A REX
BLOCK PATTERN OVER THE EASTERN PACIFIC WITH STRONG HIGH PRESSURE OFF
THE NW COAST AND LOW PRESSURE OFF THE SW COAST. THE LOW IS THEN
FORECAST TO MOVE EAST BY THE END OF THE WEEK. DUE TO A CONTINUING
HIGH DEGREE OF UNCERTAINTY...MINIMAL GRID EDITS WERE MADE. WELL
BELOW NORMAL TEMPERATURES WERE MAINTAINED DUE TO ONGOING MOUNTAIN
SNOW COVER AND VALLEY INVERSIONS.
&&
.CLIMATE...VERY COLD AIRMASS REMAINS OVER THE AREA. A FEW SITES MAY
SEE RECORD LOW MINIMUM TEMPERATURES AND RECORD LOW MAXIMUM
TEMPERATURES TODAY. BELOW IS A LIST OF RECORDS FOR SEVERAL STATIONS
IN OUR AREA.
