DISCUSSION
ANOTHER HOT DAY IS IN STORE TODAY FOR MANY VALLEY AND DESERT
LOCATIONS. HIGHS JUST ABOVE 100 DEGREES WILL OCCUR IN THE
CENTRAL VALLEY AND THE KERN COUNTY DESERT UNTIL THURSDAY. THE
PROBABILITY OF TRIPLE DIGIT READINGS REMAINS AT 35-75 PERCENT
FOR THE KERN COUNTY DESERT AND 20-50 PERCENT FOR THE SJ VALLEY
DURING THIS PERIOD. REMEMBER TO BEAT THE HEAT AND CHECK THE BACK
SEAT WHEN LEAVING YOUR VEHICLES, AS WE HAVE JUST ENTERED THE
TYPICAL HOTTEST MONTH OF THE YEAR. IN ADDITION, MOUNTAIN
THUNDERSTORMS HAVE THE POTENTIAL TO DEVELOP THIS AFTERNOON,
ALTHOUGH MAINLY TOWARDS THE HIGH COUNTRY OF YOSEMITE NP WHERE
THERE IS A 10-15 PERCENT CHANCE. THERE IS A SLIGHTLY BETTER
CHANCE (15-20 PERCENT) AS WE HEAD INTO WEDNESDAY, AND AREAS
AFFECTED INCLUDE MAINLY YOSEMITE NP SOUTHWARD TO SEQUOIA NP.
A NOTICEABLY COOLER HOLIDAY WEEKEND, WITH HIGHS MAINLY IN THE
90'S FOR THE CENTRAL VALLEY, ALSO REMAINS LIKELY, ALTHOUGH SOME
AREAS, SUCH AS THE KERN COUNTY DESERT, MAY ONLY EXPERIENCE A
MODEST DECREASE IN DAYTIME HIGHS ON INDEPENDENCE DAY AND
SATURDAY, AS TRIPLE DIGITS PERSIST THERE. THERE IS ALSO THE
POTENTIAL FOR INCREASED WINDS IN THE TYPICAL PRONE AREAS ON
THURSDAY AND INDEPENDENCE DAY. THE BEST CHANCE FOR A GUST ABOVE
40 MPH WILL BE TOWARDS MOJAVE AND THE DESERT SLOPES (ABOUT 60-90
PERCENT), WHILE GUSTS OF 30 MPH CAN BE EXPECTED (ABOUT A 50-80
PERCENT CHANCE) TOWARDS THE PASSES OF THE COASTAL RANGES,
INCLUDING PACHECO PASS, AND THE HIGHER TERRAIN ADJACENT TO THE
WEST SIDE OF THE CENTRAL VALLEY. SOME ADVISORY LEVEL GUSTS
CANNOT BE RULED OUT, BUT APPEAR TO BE LOCALIZED AT THIS TIME.
FOR NEXT WEEK, OUR REGION WILL GRADUALLY HEAT BACK UP AS HIGH
PRESSURE RIDGING REBUILDS. HOWEVER, WE'RE NOT EXPECTING
WIDESPREAD TRIPLE DIGITS IN THE VALLEY TO RETURN BY THIS TIME
NEXT WEEK.
