PARTICULARLY OVER THE SOUTHERN GREAT BASIN AND MOJAVE DESERT,
INCLUDING THE COLORADO RIVER VALLEY.

OVER THE WEEKEND INTO THE FIRST HALF OF NEXT WEEK. THIS WILL BRING

DISCUSSION
THROUGH THE MIDDLE OF NEXT WEEK.
A DRY COLD FRONT HAS BEEN PUSHING SOUTH THROUGH THE REGION AND WILL
REACH THE FAR SOUTHERN AREAS OF THE FORECAST AREA BY SUNRISE.
NORTHWEST TO NORTH WINDS BEHIND THE FRONT HAVE GENERALLY BEEN 20 TO
30 MPH WITH GUSTS TO AROUND 35 TO 40 MPH FOR MOST AREAS, BUT THE
MAIN IMPACTS WILL BE DOWN THE COLORADO RIVER VALLEY WHERE SURFACE
PRESSURE GRADIENTS WILL CONTINUE TO STRENGTHEN OVERNIGHT. THESE
GRADIENTS ALONG WITH LOCAL TERRAIN ENHANCEMENTS WILL BRING NORTHERLY
WIND GUSTS CLOSER TO 45 TO 55 MPH DOWN THE COLORADO RIVER VALLEY. A
FEW WINDY SPOTS, LIKE AROUND LAUGHLIN, MAY TOUCH 60 MPH THIS MORNING
BUT IT SHOULD BE ISOLATED AND PROBABILITIES OF REACHING 60 MPH ARE
LESS THAN 20%. THE CURRENT WIND ADVISORIES FOR THE COLORADO RIVER
VALLEY INCLUDING THE LAKE MEAD NRA WILL REMAIN IN EFFECT UNTIL
SUNSET THIS EVENING. THE STRONGEST WINDS WILL OCCUR THIS MORNING,
BUT WILL SLOWLY DIMINISH THROUGH THE AFTERNOON. BREEZY NORTH WINDS
WILL PERSIST DOWN THE LOWER COLORADO RIVER VALLEY SATURDAY, BUT ARE
EXPECTED TO REMAIN BELOW ADVISORY LEVELS. THIS COLD FRONT WILL ALSO
USHER IN SOME COOLER AIR AND HIGHS TODAY WILL BE THE COOLEST WE HAVE
SEEN SINCE EARLY MARCH AND WILL BE NEAR TO SLIGHTLY BELOW NORMAL.
OTHER THAN SOME LINGERING NORTHERLY BREEZES DOWN THE COLORADO RIVER
VALLEY SATURDAY, HIGH PRESSURE WILL START BUILDING INTO THE REGION.
THIS WILL BRING LIGHTER WINDS ALONG WITH THE START OF A WARMING
TREND. BY EARLY NEXT WEEK, TEMPERATURES WILL BE AROUND 15 DEGREES
WARMER THAN TODAY WITH LAS VEGAS ONCE AGAIN FLIRTING WITH 90
DEGREES. THE HEAT WILL PEAK ON TUESDAY BEFORE UNSETTLED WEATHER
RETURNS BY THE MIDDLE TO END OF NEXT WEEK. THERE IS STILL PLENTY OF
UNCERTAINTY IN THE MODELS WITH REGARDS TO PRECIPITATION AND GUSTY
WINDS, BUT IT DOES LOOK LIKE WE WILL BE IN A TEMPERATURE ROLLER
COASTER FOR AT LEAST ANOTHER WEEK.
