RECOVER A FEW DEGREES. ANOTHER STORM SYSTEM IN THE SOUTHERN GULF OF
ALASKA WILL BRING INCREASING WINDS TO THE SIERRAS AND THE WESTERN
MOJAVE DESERT TOMORROW. IT WILL ALSO BRING A CHANCE OF MOUNTAIN SNOW
AND VALLEY RAIN TUESDAY AND WEDNESDAY...MAINLY TO AREAS NORTH OF LAS
VEGAS.

.SHORT TERM...SATELLITE SHOWS CLEAR SKIES AREAWIDE EARLY THIS

STRONG WESTERLY WINDS EXPECTED TO IMPINGE UPON THE SIERRAS TOMORROW.
WRF/NMM CROSS SECTIONS SHOW VEERING WINDS WITH HEIGHT RESULTING IN A
MUCH LIGHTER CROSS-BARRIER COMPONENT ALOFT BY NOON. FORECAST
SOUNDINGS SHOW AN INVERSION OR ISOTHERMAL LAYER JUST ABOVE CREST
LEVEL. THESE FACTORS ARE FAVORABLE FOR DOWNSLOPE WINDS...AND THE NMM
CROSS SECTIONS SHOW 50+ KNOTS OF WIND DOWN TO THE MID-SLOPE LEVEL
DURING THE DAY. WITH FREE AIR WIND SPEEDS NEAR CREST LEVEL FORECAST
TO BE CLOSE TO 100 MPH...WILL ISSUE A HIGH WIND WATCH FOR THE
EASTERN SLOPES OF THE SOUTHERN SIERRAS. CONSIDERING THE
AFOREMENTIONED REVERSE SHEAR AND TEMPERATURE PROFILE...WILL ALSO
INCLUDE THE OWENS VALLEY DUE TO THE POSSIBILITY OF DOWNSLOPE WINDS.
THE SAME STORM WILL ALSO PRODUCE GUSTY WEST WINDS IN THE USUAL
PLACES IN THE WESTERN MOJAVE DESERT...BUT SPEEDS DO NOT APPEAR HIGH
ENOUGH TO JUSTIFY A HIGH WIND WATCH AT THIS TIME. ASIDE FROM THE
WIND ISSUES...THE SHORT TERM LOOKS QUIET WITH PRECIP CHANCES
CONFINED TO THE SIERRAS AND TEMPERATURES RECOVERING TO NEAR AVERAGE
FOR THIS TIME OF YEAR.

.LONG TERM...FOR THE PERIOD STARTING ON TUESDAY... MODELS ARE IN
GOOD AGREEMENT AS A LARGE LONGWAVE TROUGH SLOWLY MAKES ITS WAY EAST
ACROSS THE AREA TUESDAY THROUGH THURSDAY MORNING. SEVERAL SHORTWAVES

AREA TUESDAY EVENING THEN WEDNESDAY AFTERNOON ACROSS
LINCOLN...NYE...AND ESMERALDA COUNTIES. HAVE KEPT JUST 30-40 POPS AT
THE MOST SO FAR WITH NOT A WHOLE BUNCH OF MOISTURE TO WORK WITH.
AFTER THURSDAY WEAK RIDGING WILL BUILD UP OVER THE AREA LIMITING
CLOUD COVERAGE AND HELPING TEMPS CLIMB BACK UP TO AROUND CLIMO NORMS
FOR THIS TIME OF YEAR BY SATURDAY.
&&
