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.
