AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LAS VEGAS NV
1028 AM PST TUE DEC 26 2006

.SYNOPSIS...A LOW PRESSURE SYSTEM APPROACHING THE COAST TODAY WILL
SPREAD CLOUDS ACROSS THE REGION WITH SNOW BECOMING LIKELY IN THE
SIERRA. THIS STORM SYSTEM WILL MOVE ACROSS CALIFORNIA AND NEVADA
TONIGHT AND WEDNESDAY BRINGING A CHANCE OF RAIN AND MOUNTAIN SNOW
ALONG WITH LOCALLY GUSTY WINDS. HIGHER ELEVATIONS OF THE SIERRA WILL
LIKELY SEE SIGNIFICANT SNOWFALL TONIGHT INTO WEDNESDAY. COOLER
TEMPERATURES AND STRONG NORTHERLY WINDS ARE ON TAP FOR THURSDAY
BEHIND THE STORM SYSTEM.
&&

.UPDATE...NO UPDATED FORECAST WILL BE SENT. WINTER STORM WARNING FOR
THE SIERRA STILL IN EFFECT. STORM NOW IN NORTHERN CALIFORNIA IS A
BIT SLOWER IN ITS SOUTHWARD MOVEMENT THAN ANTICIPATED. HEAVY
SNOWFALL IN SIERRA WILL START A BIT LATTER THAN ANTICIPATED. THE PW
AND QPF AMOUNTS ARE ALSO LESS THAN PREVIOUSLY FORECAST. BELIEVE THE
12 INCHES ARE POSSIBLE STILL AND IN CONJUNCTION WITH 50 MPH OR
GREATER WINDS AT THE PEAKS THE WARNING LOOKS REASONABLE. OTHERWISE
NO CHANGES EXPECTED FROM PREVIOUS FORECAST REASONING.
&&

.PREV DISCUSSION...310 AM PST TUE DEC 26 2006

.SHORT TERM...SOMEWHAT MOIST FLOW AHEAD OF APPROACHING UPPER TROUGH
WILL SPREAD CLOUDS ACROSS THE FORECAST AREA TODAY ALONG WITH A
CHANCE OF RAIN AND HIGH ELEVATION SNOW OVER THE NORTHERN ZONES. SNOW
WILL BECOME LIKELY BY THIS AFTERNOON OVER THE SIERRA WITH SEVERAL
INCHES ACCUMULATION POSSIBLE ABOVE 7500 FEET. WHILE RIDGETOP WINDS
COULD BE PRETTY STRONG OVER THE SIERRA TODAY...PRECIPITATION DRAG
SHOULD HELP LIMIT SPEEDS AND DO NOT EXPECT A DOWNSLOPE WIND EVENT.
MODELS PRETTY CONSISTENT WITH BRINGING THE TROUGH INTO CA TONIGHT
AND TO THE UT/NV BORDER WEDNESDAY. BETTER DYNAMICS WITH A CONTINUED
MOIST FLOW WILL LEAD TO HEAVY SNOW OVER THE SIERRA TONIGHT INTO
WEDNESDAY AND COMBINED WITH GUSTY WINDS WILL LEAD TO WINTER STORM
WARNING CONDITIONS. UPGRADED THE WATCH TO A WINTER STORM WARNING.
OTHERWISE LOOKING AT A CHANCE OF RAIN AND SNOW SHOWERS FOR NEARLY
THE ENTIRE FORECAST AREA BY EARLY WEDNESDAY AS THE TROUGH MOVES EAST
INTO THE AREA. LOCALLY GUSTY WEST TO SOUTHWEST WINDS CAN BE EXPECTED
TONIGHT AND WEDNESDAY AND WESTERN SAN BERNARDINO COUNTY MAY WELL
MEET ADVISORY CRITERIA WEDNESDAY AFTERNOON. BASED ON MODEL
QPF...PRECIPITATION AMOUNTS OUTSIDE OF THE SIERRA DO NOT LOOK TO BE
SIGNIFICANT. TROUGH BECOMES A CLOSED LOW WEDNESDAY NIGHT AS IT MOVES
TO THE FOUR CORNERS REGION. PRECIPITATION CHANCES WILL LINGER OVER
THE EASTERN PORTION OF THE FORECAST AREA WHILE WINDS SHIFT AROUND TO
A NORTHERLY DIRECTION AND BECOME GUSTY. DRY AIR MASS MOVES IN
THURSDAY AND THURSDAY NIGHT WITH NORTHERLY GRADIENT INCREASING.
CURRENT MODEL TRENDS INDICATE PROBABLE ADVISORY CRITERIA WINDS THESE
PERIODS AND WILL NEED TO BE MONITORED FOR HEADLINES LATER SHIFTS.

.LONG TERM...RIDGING WILL BRING MOSTLY SUNNY AND DRY CONDITIONS TO
THE AREA FRIDAY AND SATURDAY. TEMPERATURES ARE EXPECTED TO REMAIN ON
THE COOL SIDE BOTH DAYS ESPECIALLY IN THE VALLEYS DUE TO THE
NORTHERLY WINDS ON FRIDAY AND LACK OF MIXING SATURDAY. THE WINDS ON
FRIDAY WILL BE STRONGEST DURING THE MORNING HOURS BEFORE SURFACE
GRADIENTS WEAKEN. THE RIDGE IS FORECAST TO FLATTEN ON SUNDAY AS A
WEAK PACIFIC STORM APPROACHES THE WEST COAST. MODELS BRING THIS
SYSTEM ACROSS THE CWA MONDAY POSSIBLY PRODUCING A FEW SHOWERS OVER
THE NORTHERN ZONE MOUNTAINS. IT IS LIMITED IN MOISTURE AND ONLY
LIGHT QPF IS EXPECTED WHERE SHOWERS FORM.

.AVIATION...TAFS AND TWEBS ADEQUATELY DESCRIBE EXPECTED WEATHER
CONDITIONS FOR AREA TERMINALS. SEE TAFS FOR KLAS...KVGT...KDRA...
