GUSTY SOUTHWESTERLY WINDS WILL CONTINUE TO INCREASE ACROSS THE
MOJAVE DESERT AND SOUTHERN GREAT BASIN THIS AFTERNOON AS A SHORTWAVE
APPROACHES THE COAST AND MOVES THROUGH THE AREA. WIND ADVISORIES
REMAIN IN EFFECT FOR THE OWENS VALLEY, DEATH VALLEY, AND ACROSS THE
MOJAVE DESERT ALONG THE I-15 CORRIDOR THROUGH LATER THIS EVENING AS
WIDESPREAD 40 TO 50 MPH WIND GUSTS CONTINUE. THE LATEST HREF SHOWS A
40 TO 50% CHANCE OF 40+ MPH DOWNSLOPE WINDS IN THE SOUTHERN OWENS
VALLEY THIS EVENING, WHICH WOULD RESULT IN HAZARDOUS CROSSWINDS
ALONG HWY 395. IN THE LAS VEGAS VALLEY, THE HREF HAS A 50 TO 75%
CHANCE OF 40+ MPH DOWNSLOPE WINDS MAKING IT TO THE WESTERN PORTION
OF THE 215 BELTWAY, WITH A 20 TO 30% CHANCE OF STRONG DOWNSLOPE
WINDS MAKING IT AS FAR INTO THE VALLEY AS RAINBOW BLVD. WITH THE
EXCEPTION OF NORTHWESTERN SAN BERNARDINO COUNTY, WINDS WILL DECREASE
OVERNIGHT AND WILL BE RELATIVELY LIGHTER ON WEDNESDAY BEFORE PICKING
BACK UP THURSDAY AS A SHORTWAVE ROLLS THROUGH THE GREAT BASIN. IN
NORTHWESTERN SAN BERNARDINO COUNTY, STRONG WESTERLY WINDS WILL
CONTINUE THROUGH THURSDAY EVENING. RIDGING WILL BUILD OVER THE AREA
ON FRIDAY AND SATURDAY, RESULTING IN GUSTY NORTH WINDS FUNNELING
DOWN THE COLORADO RIVER VALLEY.
THE LATEST SATELLITE IMAGERY SHOWS MOISTURE STREAMING FROM THE
PACIFIC INTO SOUTHERN CALIFORNIA, THROUGH SOUTHERN NEVADA, AND INTO
NORTHWESTERN ARIZONA AS A SHORTWAVE APPROACHES THE COAST. CURRENTLY,
THE ONLY EVIDENCE OF THIS MOISTURE IS OVERCAST SKIES ACROSS THE
REGION. HOWEVER, PORTIONS OF THE AREA WILL SEE PRECIPITATION CHANCES
INCREASE AS THE SHORTWAVE SWINGS THROUGH BEGINNING THIS AFTERNOON
AND CONTINUING THROUGH EARLY TOMORROW MORNING. OVERALL,
PRECIPITATION WILL BE LIGHT WITH TOTALS LESS THAN A TENTH OF AN INCH
FOR MOST PLACES. THE EASTERN SIERRA, HIGHER TERRAIN OF LINCOLN
COUNTY, SPRING MOUNTAINS, AND HIGHER TERRAIN OF THE ARIZONA STRIP
WILL BE THE EXCEPTION WITH A FEW TENTHS OF AN INCH OF RAIN POSSIBLE
THIS AFTERNOON THROUGH EARLY WEDNESDAY MORNING.
AS PREVIOUSLY MENTIONED, RIDGING WILL SET UP OVER THE REGION AS WE
HEAD INTO THE WEEKEND, RESULTING IN GUSTY NORTH WINDS DOWN THE
COLORADO RIVER VALLEY ON FRIDAY AND SATURDAY. THESE WINDS WILL LET
UP ON SUNDAY AS WE HEAD INTO NEXT WEEK, WITH TEMPERATURES REBOUNDING
TO AROUND 10 DEGREES ABOVE NORMAL BY MONDAY THANKS TO THE RIDGE.
THIS RIDGE WILL ALSO ALLOW FOR DRY CONDITIONS TO RETURN TO THE AREA.
