DISCUSSION
THE TRIPLE DIGIT HEAT WILL BE CONTINUING INTO THE WEEKEND.
TODAY, THERE IS A 80 TO 96 PERCENT PROBABILITY OF EXCEEDANCE
(POE) OF 100 DEGREES. IT MAY BRING ONLY A SMALL COMFORT, BUT THE
POE OF 104 DEGREES IS ONLY 10 PERCENT FOR MOST LOCATIONS. SMALL
VICTORIES...SATURDAY LOOKS TO BE A SIMILAR STORY, AS THE POE FOR
100 DEGREES IS AGAIN HIGH - 80 TO 94 PERCENT. BOTH TODAY AND
TOMORROW, THE MOJAVE DESERT WILL EXCEED 100 DEGREES. BY SUNDAY,
THE POE FOR 100 GOES DOWN TO 40 TO 70 PERCENT, WITH THE HIGHEST
PERCENT CHANCE BEING BAKERSFIELD. IN THE MOJAVE DESERT, THEIR
POE IS ONCE AGAIN NEAR 100 PERCENT. WITH THESE HOT TEMPERATURES,
THERE IS A MODERATE HEATRISK FOR THE SJ VALLEY. IT IS SUMMER
TIME, SO HOT TEMPERATURES ARE EXPECTED. HOWEVER, THOSE THAT
MIGHT NOT BE ACCLIMATED, THE GROUPS OVER 65 YEARS OF AGE,
INFANTS AND THOSE WITHOUT ACCESS TO AC MAY BE AT RISK, SO TAKE
PRECAUTIONS WHERE NEEDED. OVERNIGHT LOWS ARE TO BE IN THE 60-70
DEGREE RANGE, WITH THE 70'S MORE LIKELY TO BE IN THE
METROPOLITAN AREAS. AS SUCH, THERE IS A HEAT ADVISORY IN PLACE
UNTIL 11 PM SATURDAY NIGHT.
BY SUNDAY, THERE IS STILL WIDESPREAD MODERATE HEAT RISK FOR THE
VALLEY AS WE CONTEND WITH SIMILAR TEMPERATURES (YES, THE TRIPLE
DIGITS TOO) UNTIL THE MIDDLE OF NEXT WEEK. THERE WILL ALSO BE
DRY CONDITIONS AS RELATIVE HUMIDITY WILL BE BETWEEN 8-20
PERCENT. THIS IS CREATING MODERATE RISK OF FIRE DANGER INCLUDING
GRASS FIRES. HOWEVER, THERE IS A 10-15 PERCENT CHANCE OF AN
ISOLATED THUNDERSTORM OR TWO IN THE SIERRA NEVADA'S. BY
THURSDAY, THERE WILL BE A LOW PASSING THROUGH THE PACIFIC
NORTHWEST WHICH WILL AID IN DISRUPTING THE RIDGE IN PLACE. AS
SUCH, TEMPERATURES WILL COOL INTO THE MID TO LOW 90S. STILL
WARM, BUT IT COULD BE WORSE!
AS PEOPLE ATTEMPT TO COOL DOWN FROM THESE HOT TEMPERATURES,
PLEASE REMEMBER THAT WATERWAYS ARE STILL RUNNING COLD. EVEN THE
MOST EXPERIENCED SWIMMERS CAN LOSE DEXTERITY IN 10-15 MINUTES IN
WATER THAT IS 50 TO 60 DEGREES.
