THROUGH NEXT WEEK.
BREEZY NORTHERLY WINDS CONTINUE TODAY AS A SHORTWAVE SWINGS THROUGH
UTAH AND ARIZONA. THE HIGHEST GUSTS SO FAR TODAY HAVE BEEN DOWN THE
COLORADO RIVER VALLEY BETWEEN 30 AND 40 MPH. ELEVATED WINDS SHOULD
LAST THROUGH SUNSET AND WEAKEN OVERNIGHT. TEMPERATURES INCREASE
TODAY AND TOMORROW AS A SHORTWAVE RIDGE PASSES THROUGH AND HEIGHTS
ALOFT RISE. THE RIDGE STARTS TO DRIFT EAST AND HEIGHTS ALOFT
DECREASE ON SUNDAY AS LOW PRESSURE MOVES INTO THE WEST COAST, BUT
SUFFICIENT MIXING SHOULD ALLOW FOR MORE WARMING FOR THE EASTERN HALF
OF THE FORECAST AREA. IN LAS VEGAS, THERE IS A 75 PERCENT
PROBABILITY OF REACHING A HIGH OF 90 DEGREES ON SUNDAY AT KLAS.
THE PREVIOUSLY MENTIONED LOW PRESSURE SYSTEM WILL LEAD TO INCREASED
WINDS, PRECIPITATION CHANCES, AND COOLER TEMPERATURES NEXT WEEK.
STRONG 850 MB WINDS SUPPORT GUSTY SOUTHERLY TO SOUTHWESTERLY WINDS
STARTING ON SATURDAY AFTERNOON IN SOUTHEASTERN CALIFORNIA,
RAMPING UP AND SPREADING EAST ON SUNDAY. THE STRONGEST WINDS
SHOULD OCCUR OVER HIGH TERRAIN. HOWEVER, THERE ARE GREATER THAN 70
PERCENT PROBABILITIES FOR GUSTS OVER 40 MPH IN CERTAIN VALLEYS IN
INYO AND SAN BERNARDINO COUNTIES, AS WELL AS THE COLORADO RIVER
VALLEY. ELEVATED WINDS MAY ALSO CONTINUE INTO MONDAY IN THE
WESTERN MOJAVE DESERT AS THE LOW SLOWLY EXITS TO THE EAST. WILL
CONTINUE TO MONITOR TO DETERMINE IF WIND HEADLINES BECOME
NECESSARY. PRECIPITATION CHANCES FAVOR THE EASTERN SIERRA AND
SOUTHERN GREAT BASIN ON MONDAY AND TUESDAY. A FEW INSTABILITY
DRIVEN SHOWERS AND THUNDERSTORMS ARE POSSIBLE AREAWIDE LATER ON
TUESDAY AND WEDNESDAY AS THE CENTER OF THE LOW PASSES OVERHEAD.
TEMPERATURES DROP 10 TO 15 DEGREES BETWEEN SUNDAY AND TUESDAY
