&&

.PREV DISCUSSION...350 PM PST SAT FEB 23...STRONG PACIFIC STORM
SPINNING OFF THE CALIFORNIA COAST THIS AFTERNOON HAS BROUGHT
INCREASING CLOUDS TO THE FORECAST AREA WITH SOME LIGHT SNOW
BEGINNING IN THE SIERRA. STORM SYSTEM WILL FILL SUBSTANTIALLY AS IT
MOVES ONSHORE BUT WILL STILL HAVE ENOUGH MOISTURE AND FORCING TO
PRODUCE SIGNIFICANT SNOWFALL OVER THE SIERRA TONIGHT AND SUNDAY WITH
A BIT OF SNOW OVER THE HIGH ELEVATIONS OF SOUTHERN NEVADA. SNOW
LEVELS WILL BE PRETTY HIGH INITIALLY WITH SOUTHERLY FLOW...LIKELY
ABOVE 7500 FEET...THEN DROP TO ABOUT 6000-6500 SUNDAY. EXPECTING UP
TO ABOUT 8 INCHES OF SNOW IN THE SPRING MOUNTAINS AND WENT WITH A
SNOW ADVISORY THERE. SNOWFALL AMOUNTS SHOULD REMAIN BELOW ADVISORY
CRITERIA IN LINCOLN AND CENTRAL NYE COUNTIES DUE IN PART TO THE HIGH
SNOW LEVELS BUT THEY COULD SEE A FEW INCHES OF SNOW. VALLEY
LOCATIONS WILL GENERALLY SEE SCATTERED RAIN SHOWERS SUNDAY AS THE
OPEN TROUGH MOVES INTO NEVADA. AIR MASS BECOMES SLIGHTLY UNSTABLE BY
SUNDAY AFTERNOON WITH ISOLATED THUNDERSTORMS NOT OUT OF THE QUESTION
ACROSS THE NORTHERN PART OF THE FORECAST AREA. WINDS WILL ALSO BE
INCREASING AS THIS STORM MOVES IN. STILL A BIT UNCERTAIN ABOUT WIND
SPEEDS GIVEN THE WIDESPREAD RISING MOTION AND WEAK INSTABILITY WHICH
IS NOT FAVORABLE FOR DOWNSLOPE WINDS. ALSO THE SURFACE GRADIENT WILL
BE SOUTHEASTERLY AT LEAST INITIALLY WHICH ALSO DOES NOT FAVOR STRONG
DOWNSLOPE WINDS ALONG THE EAST SLOPES OF THE SPRING MOUNTAINS AND
WESTERN LAS VEGAS VALLEY. THEREFORE CANCELLED THE HIGH WIND WATCH.
DID GO WITH A WIND ADVISORY FOR THE SPRING MOUNTAINS AND SHEEP RANGE
AS WINDS AT AND NEAR RIDGETOP LEVELS SHOULD BE GUSTING OVER 50 MPH.
WINDS AND PRECIPITATION WILL BE DECREASING/ENDING SUNDAY NIGHT AS
THE WEAKENING UPPER TROUGH MOVES INTO THE ROCKY MOUNTAIN REGION.
HIGH PRESSURE WILL START TO BUILD OVER THE AREA MONDAY AND MONDAY
NIGHT LEADING TO DRY AND MILD CONDITIONS. THERE WILL BE A BIT OF A
NORTHERLY BREEZE DOWN THE COLORADO RIVER VALLEY MONDAY AND MONDAY
NIGHT BUT DOES NOT LOOK TOO IMPRESSIVE AT THIS TIME.

.LONG TERM...STILL LOOKING FOR A QUIET LONG TERM WITH THE MAJOR
FEATURE BEING A RIDGE OVER THE AREA. TWO FEATURES DO APPEAR DURING
THE WEEK. A TROUGH WILL DROP DOWN THE BACKSIDE OF THE RIDGE TO OUR
NORTHEAST ON THURSDAY. FOR NOW THIS LOOKS LIKE A DRY EVENT FOR US
WITH THE ONLY THING TO WATCH FOR WOULD BE WINDS FROM THE NORTH
BREEZY IN THE COLORADO RIVER VALLEY BEHIND THE ASSOCIATED COLD
FRONT. FOR NOW MODELS DO NOT SHOW THAT GREAT A PRESSURE GRADIENT TO
SUPPORT MENTIONING THE WINDS YET.  NEXT EVENT IS ANOTHER
TROUGH/FRONT DROPPING INTO THE GREAT BASIN SATURDAY OR
SUNDAY...DEPENDING ON MODEL OF CHOICE. IN ANY SCENARIO DEPICTED THE
SYSTEM SHOULD ONLY BE A TEMPERATURE DROP AND SOME CLOUDS.
