AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
900 PM PST MON FEB 27 2006

.SYNOPSIS...DEEP SUBTROPICAL MOISTURE WILL CONTINUE TO FLOW INTO THE
SOUTHERN SIERRA THIS EVENING...AND SPREAD ACROSS THE MOJAVE DESERT
AND SOUTHERN GREAT BASIN TONIGHT AND TUESDAY. SIGNIFICANT RAIN AND
SNOW AMOUNTS ARE LIKELY WITH THIS STORM SYSTEM...BUT SNOW LEVELS ARE
EXPECTED TO REMAIN HIGH. THERE WILL BE A BRIEF LULL IN THE MIDDLE OF
THE WEEK BEFORE A COLDER STORM SYSTEM MOVES IN THURSDAY AND FRIDAY.
&&

.UPDATE...WEVE SEEN A FEW LIGHT SHOWERS DEVELOP OUT AHEAD OF MAIN
PLUME OF SUBTROPICAL MOISTURE AND MOVE ACROSS THE LAS VEGAS VALLEY
AND NORTHWEST ARIZONA THIS EVENING. SATELLITE SHOWS MAIN FETCH OF
MOISTURE STILL STREAMING IN OVER LA BASIN...SOUTHERN SIERRA AND UP
ACROSS CENTRAL NEVADA. AT LAST CHECK ABOUT 2 HOURS AGO...SPOTTER IN
ASPENDELL REPORTED 4 INCHES ON THE GROUND AND FALLING AT A RATE OF
ABOUT AN INCH AN HOUR. WINTER STORM WARNING LOOKS GOOD. AS FAR AS
THE SOUTHERN NEVADA MOUNTAINS. LATEST CHECK OF TEMPERATURES AROUND
7500 FEET SHOWS READINGS IN THE MID 30S. OROGRAPHICS WILL BE A BIG
CONTRIBUTOR TO TOTAL PRECIPITATION AMOUNTS AS THREE TO FOUR TENTHS
OF AN INCH OF RAIN ALREADY HAS FALLEN ON THE MOUNTAIN. BASED OFF
TEMPERATURES SNOW LEVEL PROBABLY AROUND 8500 FEET AND WILL LEAVE
WINTER WEATHER ADVISORY POSTED AS SNOW LEVELS LOWER BY DAYBREAK
TUESDAY. ON TUESDAY...MAIN PLUME OF MOISTURE SAGS SOUTHEAST AND IS
AIMED ACROSS ARIZONA WITH MID-LEVEL BAROCLINIC BAND SLOWLY SAGGING
SOUTHEAST ACROSS THE SOUTHERN GREAT BASIN. PRECIPITATION WILL
TRANSITION FROM STRATIFORM RAIN TO SHOWERS AS COLD AIR ALOFT WITH
BAROCLINIC ZONE APPROACHES. MAY SEE A FEW LIGHTNING STRIKES ACROSS
NORTHERN ZONES BUT WILL NOT INCLUDE IN UPDATE AS EXPECT COVERAGE
WOULD BE VERY ISOLATED. UPDATED PACKAGE CONCENTRATING ON FIRST
PERIOD MODIFICATION WILL BE OUT SHORTLY.
&&

.PREV DISCUSSION...312 PM PST MON FEB 27 2006...SO FAR SO GOOD. SNOW
LEVELS STARTING OFF EVEN HIGHER THAN EXPECTED. ASPENDELL...AT 8500
FEET IN THE SIERRAS...HAD RAIN OVERNIGHT WHICH HAS CHANGED TO A RAIN
AND SNOW MIX TODAY. COLDER AIR LURKING JUST UPSTREAM FROM THERE
SHOULD KICK SNOW LEVELS DOWN 1000 FEET OR SO OVERNIGHT...WHILE
SUBTROPICAL MOISTURE BEING FORCED UP AND OVER THE MOUNTAINS GETS
WRUNG OUT OVER AND JUST EAST OF THE CREST. TONED DOWN SNOWFALL
AMOUNTS A LITTLE OUT OF RESPECT FOR WARM AND WET GROUND...BUT SHOULD
HAVE NO PROBLEM MEETING WARNING CRITERIA. NEXT FOCUS IS THE CLARK
COUNTY MOUNTAINS. 12 KM NAM MODEL PRODUCES ALMOST 1.5 INCHES OF QPF
THERE...WHILE RIVER FORECAST CENTER QPF IS A MORE REASONABLE TWO
THIRDS OF AN INCH OR SO. CHALLENGE IS PRECIP TYPE/SNOW LEVEL...WHICH
IS PROBABLY CLOSE TO 9000 FEET NOW AND SHOULD FALL QUICKLY AS THE
PRECIP WINDS DOWN. TOOK THE MIDDLE OPTION OF THREE...ISSUING A
WINTER WEATHER ADVISORY FOR 4-7 INCHES OF SNOW...WHICH COULD OCCUR
IN JUST A FEW HOURS TOWARD THE END OF THE HEAVY PRECIP TOMORROW
MORNING. NEXT SHIFT WILL NEED TO MONITOR THIS FOR THE POTENTIAL OF
UPGRADING IF HEAVIER SNOW IS FORECAST...OR CANCELING IF SNOW LEVELS
REMAIN HIGH WHILE DEEPER MOISTURE IS PRESENT. SIGNIFICANT PRECIP
SHOULD BE OVER TUESDAY EVENING...WITH MOUNTAIN SHOWERS LINGERING
INTO WEDNESDAY MORNING. LOW CONFIDENCE IN TEMPERATURE FORECASTS
TONIGHT AND TOMORROW. WARM ADVECTION AND EVAPORATIVE COOLING WILL
BATTLE IT OUT OVERNIGHT...AND LINGERING CLOUDS/PRECIP WILL CAUSE
FITS TOMORROW.

.LONG TERM...MODELS IN GOOD AGREEMENT WITH UPPER LOW POSITIONED WEST
OF VANCOUVER ISLAND THURSDAY MORNING AND ENERGY ROTATING AROUND THE
BASE AND INTO OREGON/NORTHERN CALIFORNIA. HOWEVER...THIS REPRESENTS
A SLOWING OF THE SYSTEM AND HAVE BACKED OFF POPS TO SLIGHT CHANCES
EVERYWHERE EXCEPT FOR THE HIGHER ELEVATIONS OF THE SIERRA WHERE ONLY
LOW CHANCE POPS ARE FORECAST. THE LOW BEGINS TO SINK SOUTH ALONG THE
COAST THURSDAY NIGHT INTO FRIDAY WITH SHORTWAVE ENERGY MOVING INTO
CENTRAL CALIFORNIA THURS NGT AND ACROSS NORTHERN/CENTRAL NEVADA
FRIDAY. ADJUSTED POPS DOWN SLIGHTLY FRIDAY/FRIDAY NGT...ESPECIALLY
FURTHER SOUTH AS THE NEWER MODEL RUNS ARE KEEPING DYNAMICS AND
DEEPER MOISTURE NORTH OF THE CWA. CONTINUED TO CARRY LIKELY POPS
OVER THE NORTHERN MTNS DURING THIS TIME FRAME HOWEVER SINCE THESE
AREAS WILL BE IN THE BEST POSITION TO SEE PRECIP FROM THIS SYSTEM.
SHORTWAVE RIDGING BEHIND THE SYSTEM SATURDAY WILL BRING DRY
CONDITIONS TO START THE WEEKEND. SOME MODEL DISAGREEMENT BEGINS TO
APPEAR WITH THE NEXT SYSTEM IN THE CHAIN SET TO IMPACT THE AREA BY
LATE IN THE WEEKEND OR EARLY NEXT WEEK. IF CLOUD COVER DOES NOT
THICKEN TO MUCH THURSDAY...TEMPS COULD BE WARMER THAN FORECAST BUT
ARE STILL EXPECTED TO DROP BELOW NORMAL ON FRIDAY.
&&

.AVIATION...A MOIST LOW PRESSURE SYSTEM OFF THE COAST IS STILL
EXPECTED TO BRING GRADUALLY LOWER CEILINGS AS IT MOVES FROM WEST TO
EAST ACROSS THE AREA TONIGHT. ISOLATED GUSTY SOUTH TO SOUTHWEST
WINDS WILL TURN MORE WIDESPREAD THIS EVENING. MVFR CONDITIONS ARE
BEING REPORTED IN THE BISHOP AREA WITH CEILINGS AND VISIBILITY
LOWERING IN LIGHT RAIN. CEILINGS WILL BEGIN TO LOWER BELOW 10KFT IN
SOUTHERN NEVADA AND SOUTHEAST CALIFORNIA THIS EVENING...AND COULD
LOWER TO NEAR 5KT IN RAIN SHOWERS OVERNIGHT.

TAFS AND TWEBS ADEQUATELY DESCRIBE EXPECTED WEATHER
CONDITIONS. SEE TAFS FOR KLAS...KVGT...KDRA...KBIH...KDAG...KEED.
