AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
650 PM PST FRI DEC 7 2007
.SYNOPSIS...AN AREA OF LOW PRESSURE WILL LINGER OVER THE GREAT BASIN
AND MOJAVE DESERT THROUGH THE WEEKEND. RAIN AND SNOW SHOWERS WILL
OCCUR WITH THE SNOW LEVEL DROPPING TO 3500 FEET SATURDAY NIGHT.
TEMPERATURES WILL FALL BELOW NORMAL OVER THE WEEKEND. THE SYSTEM
WILL FINALLY START MOVING EAST OF THE AREA EARLY NEXT WEEK...
HOWEVER TEMPERATURES WILL STAY ON THE COOL SIDE. &&
.UPDATE...CANCELLED THE WIND ADVISORY FOR SAN BERNARDINO COUNTY A
COUPLE OF HOURS EARLY. WINDS HAVE DIMINISHED BELOW ADVISORY LEVEL.
ELSEWHERE...HAVE INCREASED POPS SLIGHTLY OVER PORTIONS OF INYO
COUNTY...ESMERALDA...AND CENTRAL NYE OVER THE NEXT FEW HOURS. ALSO
ADDED ISOLATED THUNDERSTORMS THOSE AREAS AND ACROSS THE NORTHWEST
PLATEAU OF ARIZONA. TWO SEPARATE MECHANISMS RESPONSIBLE FOR THOSE
TWO AREAS. STRONG JET...SUBSTANTIAL MOISTURE AND VORT LOBE ENHANCING
LIFT OVER THE NORTHERN HALF OF MOHAVE COUNTY. A SECOND VORT
LOBE...SUBSTANTIALLY COLDER AIR ALOFT SUFFICIENT VERTICAL MOTION
PROVIDING SECOND AREA OVER EASTERN INYO...NYE...ESMERALDA.
CONSIDERING INCREASING POPS OVER THE CENTRAL PORTION OF THE CWA
OVERNIGHT AND ENHANCING QPF A BIT FOR THE OVERNIGHT HOURS. WILL
LIKELY ACTIVATE SNOW ADVISORY A FEW HOURS EARLIER FOR THE SPRING
MOUNTAINS BASED ON THE LATEST TRENDS AND OBSERVATIONS.
.PREV DISCUSSION...THE MAIN FEATURES WHICH WILL INFLUENCE THE
WEATHER TONIGHT THROUGH SUNDAY ARE TWO SHORTWAVES DIVING DOWN FROM
THE NORTH. WATER VAPOR AND THE 18Z NAM/GFS SHOWED THE FIRST
CIRCULATION DROPPING OUT OF EASTERN OREGON INTO NORTHWEST NEVADA AND
THE SECOND OVER WESTERN BRITISH COLUMBIA. BOTH THE GFS AND NAM
INDICATE BROAD UPWARD FORCING DEVELOPING OVER THE FORECAST AREA
TONIGHT AND A COLDER AIR MASS SPREADING SOUTH. BOTH THE GFS AND NAM
ALSO INDICATE SUBSTANTIAL LOW TO MID LEVEL CONVERGENCE DEVELOPING
AHEAD OF THE SYSTEM FROM LINCOLN COUNTY DOWN THROUGH CENTRAL CLARK
COUNTY BETWEEN 06Z AND 18Z THEN SHIFTING EAST AND WEAKENING SATURDAY
AFTERNOON. MOISTURE IS SOMEWHAT LIMITED BUT INSTABILITY AND THE
FRONT SHOULD HELP SUSTAIN A BAND OF SHOWERS ACROSS THIS AREA LATE
TONIGHT THROUGH SATURDAY. THE SOUTHERN NEVADA MOUNTAINS AND MUCH OF
LINCOLN COUNTY SHOULD SEE SNOW ACCUMULATIONS AROUND 4 TO 8 INCHES
WHICH WARRANTS A SNOW ADVISORY. NEED TO WATCH FOR THE POSSIBILITY OF
HEAVY SNOW...ESPECIALLY IN LINCOLN COUNTY...ASSOCIATED WITH THIS
FRONTAL BAND. THE SECONDARY WAVE IS THEN FORECAST TO DIVE DOWN
THROUGH CENTRAL AND SOUTHERN CALIFORNIA SATURDAY NIGHT AND SUNDAY.
THE GFS AND ECMWF TAKE IT A LITTLE FARTHER WEST THAN THE NAM AND
DEVELOP A CLOSED LOW OFF SAN DIEGO BY SUNDAY MORNING. IT IS FORECAST
TO CONTINUE DIVING SOUTH TOWARD THE BAJA SPUR BY MONDAY MORNING.
THIS WILL PROVIDE A REINFORCING SHOT OF COLD AIR SATURDAY NIGHT AND
SUNDAY. SNOW LEVELS SHOULD BE DOWN NEAR 3000-3500 FEET LATE SATURDAY
NIGHT AND SNOW SHOWERS THAT DO DEVELOP HAVE A GOOD CHANCE OF MAKING
IT TO THE VALLEYS AND HIGHER DESERT AREAS. HOWEVER...PRECIPITATION
WILL BE IN THE FORM OF ISOLATED TO SCATTERED SHOWERS AND SHOULD NOT
BE WIDESPREAD.
.LONG TERM...BASICALLY GOOD MODEL AGREEMENT WITH UPCOMING EXTENDED
WEATHER PATTERN. A LOW PRESSURE SYSTEM OVER NORTHERN BAJA ON
MONDAY EJECTS EAST AND GETS ABSORBED INTO THE FLOW AS ANOTHER LOW
DROPS SOUTHWARD THROUGH THE GREAT BASIN. THIS NEXT SYSTEM TAKES A
SIMILAR TRACK TO THE PREVIOUS ONE BUT IS FURTHER EAST AND IS
FORECAST TO HAVE LESS AVAILABLE MOISTURE. THE ECMWF SOLUTION IS
FAIRLY DRY WITH THE SYSTEM BUT TAPS INTO MOISTURE FROM THE
PREVIOUS SYSTEM. THE TRACK ALONG THE NEVADA/UTAH BORDER HOWEVER IS
NOT ALL THAT FAVORABLE FOR PRODUCING A NOTABLE PRECIP EVENT WITHIN
THE CWA. THE GFS IS MORE BULLISH WITH SYSTEM MOISTURE AND WHEN
COMBINED WITH A LOW CENTER TRACK A LITTLE FURTHER WEST THAN THE
EURO...INDICATES LIGHT SHOWER ACTIVITY ACROSS MUCH OF THE CENTRAL
AND EASTERN CWA MONDAY NIGHT INTO TUESDAY. COMPROMISED BETWEEN THE
TWO SOLUTIONS FOR THIS FORECAST PACKAGE KEEPING PRECIP CHANCES
CONFINED TO LINCOLN AND MOHAVE COUNTIES MONDAY NIGHT AND JUST
MOHAVE COUNTY ON TUESDAY. DISREGARDING THE 18Z GFS SOLUTION BEYOND
TUESDAY...BOTH MODELS ARE VERY SIMILAR AND FORECAST FEW SURPRISES
UNDER A DRY NORTHWEST FLOW. TEMPERATURES TO REMAIN BELOW NORMAL
THROUGH THE PERIOD AS THE SYSTEM MOVING IN FROM THE NORTH ON
TUESDAY BRINGS A REINFORCING SHOT OF COLD AIR. DAYTIME WARMING
BACK CLOSER TO NORMAL IS POSSIBLE BY THE END OF THE WEEK AS THE
AIRMASS MODIFIES. &&
.AVIATION...FOR MCCARRAN...THE AREA WILL REMAIN IN AN UNSETTLED
WEATHER PATTERN THROUGH SUNDAY AS A LOW PRESSURE SYSTEM DRIFTS
SOUTHWARD OVER THE AREA. SCATTERED CLOUDS WILL PERSIST OVERNIGHT
WITH A BROKEN DECK BELOW 10K FT RETURNING AFTER 12Z SATURDAY.
SHOWERS ARE POSSIBLE WITH CIGS AT OR BELOW 8K FT AFTER MIDNIGHT AND
CONTINUING THROUGH EARLY SATURDAY MORNING. SUSTAINED SOUTHWEST WINDS
AROUND 15-20 KTS WITH GUSTS UP TO 30 KTS EXPECTED THROUGH THE
EVENING THEN DECREASING TO 10-15 KTS OVERNIGHT. ISOLATED SHOWERS
WILL REMAIN AROUND THE AREA THROUGH SUNDAY MORNING.
FOR THE REST OF SOUTHERN NEVADA...NORTHWEST ARIZONA...AND SOUTHEAST
CALIFORNIA...A LOW PRESSURE SYSTEM MOVING SOUTH OVER THE AREA WILL
BRING UNSETTLED WEATHER THROUGH SUNDAY. GUSTY SOUTHWEST WINDS WILL
CONTINUE THROUGH MUCH OF TODAY BEFORE DECREASING IN ALL BUT FAVORED
AREAS INCLUDING KDAG. ISOLATED TO SCATTERED SHOWER ACTIVITY WILL
CONTINUE OVER MUCH OF THE REGION THROUGH SUNDAY WITH CEILINGS
LOWERING BELOW 8K FEET AT TIMES.
