DISCUSSION
THROUGH THE MIDDLE OF NEXT WEEK.
GUSTY WINDS HAVE BEEN REPORTED SO FAR TODAY ACROSS MUCH OF THE
REGION IN RESPONSE TO AN TROUGH MOVING THROUGH NORTHERN NEVADA.
WIDESPREAD SOUTHWESTERLY GUSTS OF 25-35 MPH HAVE BEEN REPORTED, WITH
HIGHER GUSTS OVER 40 MPH REPORTED IN THE WESTERN MOJAVE DESERT WHERE
A WIND ADVISORY IS IN EFFECT. THESE CONDITIONS ARE EXPECTED TO
CONTINUE THROUGH THIS EVENING, WITH THE HIGHEST WINDS AND RISK FOR
IMPACTS BEING IN THE WESTERN MOJAVE DESERT THROUGH EARLY TONIGHT.
MEANWHILE FURTHER NORTH- A COLD FRONT WILL DROP THROUGH THE REGION
TODAY AND TONIGHT. THIS WILL RESULT IN BREEZY NORTH WINDS TONIGHT
AND FRIDAY. WITH THE HELP OF TERRAIN ENHANCEMENT, THE STRONGEST
WINDS WILL BE DOWN THE COLORADO RIVER VALLEY AND A WIND ADVISORY
GOES INTO EFFECT THERE TONIGHT AND CONTINUES THROUGH FRIDAY. GUSTS
OVER 40 MPH ARE LIKELY IN THE COLORADO RIVER VALLEY THROUGH THE
PERIOD, WITH THE STRONGEST WINDS FRIDAY MORNING. A FEW WINDY SPOTS,
LIKE AROUND LAUGHLIN, MAY TOUCH 60 MPH FRIDAY MORNING BUT IT SHOULD
BE ISOLATED. THE PROBABILITY FOR GUSTS OVER 60 MPH IN PLACES OUTSIDE
OF LAUGHLIN WAS 20% OR LESS, AND THE 850MB JET TOPS OUT AROUND 40KT
PER THE HREF, SO DID NOT UPGRADE THE WIND PRODUCTS AT THIS TIME.
ELSEWHERE ON FRIDAY, NORTH WINDS WILL GUST 25-35 MPH. BEHIND THE
FRONT, COLDER AIR WILL BE USHERED IN. HIGH TEMPERATURE POST-FRONTAL
WILL BE NEAR NORMAL FOR THE FIRST TIME IN A WHILE.
THE BREEZY CONDITIONS MAY LINGER INTO THE SATURDAY IN THE COLORADO
RIVER VALLEY ON SATURDAY AS TROUGHING IS REPLACED WITH BUILDING
HEIGHTS, BUT WINDS WILL BE MUCH LOWER THAN FRIDAY AND BE DIMINISHING
THROUGH THE DAY- SO DID NOT EXTEND THE WIND ADVISORY INTO SATURDAY
AT THIS TIME. WILL NEED TO WATCH WIND SPEEDS AND HOW LONG THE NORTH
WINDS WILL PERSIST AS LINGERING BOATING HAZARDS ARE POSSIBLE ON THE
LAKES ON SATURDAY. ANYONE BOATING ON SATURDAY SHOULD CHECK THE
FORECAST AND LAKE CONDITIONS BEFORE HEADING OUT. OTHERWISE, WINDS
WILL BE MUCH LIGHTER ON SATURDAY ACROSS THE REGION. TEMPERATURES
WILL ALSO BEGIN TO REBOUND ON SATURDAY AS HEIGHTS RISE WITH THE
INCOMING RIDGE. THIS TRENDS OF LIGHT WINDS AND WARMING TEMPERATURES
WILL CONTINUE ON SUNDAY AND INTO NEXT WEEK AS HIGH PRESSURE BUILDS
OVER THE REGION. ABOVE NORMAL TEMPERATURES ARE EXPECTED AGAIN BY
SUNDAY. ONE NOTE- COMPARED TO THIS PREVIOUS "HEAT DOME" WE JUST
EXPERIENCED, THIS WILL NOT BE AS STRONG AND THUS NOT EXPECTING
TEMPERATURES TO CLIMB AS HIGH. WELL ABOVE NORMAL HIGH TEMPERATURES
AND A FEW RECORD HIGHS ARE POSSIBLE NEXT WEEK AS WE CLIMB ABOUT 10-
15 DEGREES ABOVE NORMAL BY TUESDAY. BEYOND MIDWEEK, MUCH UNCERTAINTY
EXISTS WITH ENSEMBLES SUGGESTING THE PATTERN MAY TRANSITION BACK TO
A MORE ACTIVE AND COOLER WITH ONE WITH OPPORTUNITIES FOR WEAK UPPER
WAVES/TROUGHS EMERGING FROM THE PACIFIC. HOWEVER, CONFIDENCE ON
THEIR EVENTUAL PROGRESSION AND MEANINGFUL LOCAL IMPACTS REMAINS LOW.
