DISCUSSION
THROUGH THE WEEKEND.
QUIET CONDITIONS DOMINATE THE REGION THIS AFTERNOON THOUGH BREEZY
NORTH WINDS CONTINUE. THESE WINDS ARE MOST NOTABLE NEAR LAKE
MOHAVE AND LAUGHLIN, WHERE THE WINDS HAVE BEEN GUSTING IN THE
45-50 MPH RANGE AS WINDS FUNNEL DOWN THE RIVER VALLEY. WINDS WILL
GRADUALLY SUBSIDE TONIGHT AS PRESSURE GRADIENTS EASE. OTHERWISE,
ANOTHER COOL NIGHT IS IN STORE - ESPECIALLY FOR LOCATIONS WHERE
THE WINDS DROP OFF QUICKLY. BARSTOW-DAGGETT DROPPED TO 32 THIS
MORNING, MARKING THEIR FIRST FREEZE OF THE WINTER SEASON, AND
PARTS OF THE LAS VEGAS VALLEY DROPPED INTO THE 30S. SIMILAR LOW
TEMPERATURES ARE EXPECTED AGAIN TONIGHT, THOUGH SOME INCREASING
CIRRUS WILL BEGIN MOVING IN LATE TONIGHT WHICH MAY MODERATE THE
TEMPERATURE CURVE SLIGHTLY.
ON TUESDAY, HIGH CLOUDS WILL BEGIN TO STREAM IN FROM THE SOUTH
AHEAD OF A LOW PRESSURE SYSTEM LURKING OFF THE BAJA COAST. THIS
SYSTEM IS ON TRACK TO SPREAD RAIN CHANCES INTO THE MOJAVE DESERT
WEDNESDAY THAT WILL CONTINUE INTO NEW YEARS DAY AS A SHORTWAVE
LIFTS INTO THE GREAT BASIN. WHILE MOISTURE WILL BE RATHER ABUNDANT
GIVEN THE SUBTROPICAL ORIGIN, DYNAMICS WILL BE FAIRLY WEAK. THIS
LENDS TO THE LIKELIHOOD OF GENERALLY LIGHT RAINFALL EXPECTATIONS,
BUT ENOUGH RAIN TO DAMPEN NYE FESTIVITIES AND RESULT IN SOME WET
ROADWAYS. SNOW LEVELS WILL BE QUITE HIGH, GENERALLY ABOVE 9500
FEET AREAWIDE ON WEDNESDAY, AND ONLY DROPPING VERY SLIGHTLY ON
THURSDAY. THIS WILL LIMIT ANY SNOWFALL IMPACTS TO ALL BUT THE
HIGHEST PEAKS IN THE FORECAST AREA. ADDITIONAL TROUGHING ALONG
THE WEST COAST WILL KEEP PRECIP CHANCES GOING FRIDAY AND INTO THE
WEEKEND, MAINLY FOR THE SIERRA AND SOUTHERN GREAT BASIN.

PERIOD.

CALIFORNIA...FOR THE 00Z FORECAST PACKAGE...ELEVATED AND GUSTY
NORTHERLY WINDS WILL CONTINUE THROUGH THE LOWER COLORADO RIVER
VALLEY THE NEXT 24 HOURS, WHERE TERRAIN WILL FAVOR GUSTS TO
20-25KT AT KEED THROUGH SUNSET AND AGAIN TUESDAY AFTERNOON. AT

SUSTAINED SPEEDS THERE WILL DROP TO AROUND 20KT THIS EVENING
ONWARD. ELSEWHERE, NORTHERLY TO NORTHEASTERLY WINDS AROUND 8-10KT
ARE EXPECTED THROUGH SUNSET THIS EVENING, THEN BECOMING LIGHT AND
