DISCUSSION
HEAT ADVISORY IN EFFECT FOR THE MAJORITY OF THE AREA UNTIL 11
PM TUESDAY.
THE HEAT CONTINUES, WITH THE MAJORITY OF THE VALLEY SITTING AT
A 50-80% CHANCE TO EXCEED 100 DEGREES IN THE SOUTHERN HALF OF
THE VALLEY ON MONDAY AND A 15-30% CHANCE IN THE NORTHERN HALF.
THE RIDGE LOOKS TO REMAIN QUITE STABLE AS THE WEEK BEGINS, WITH
HIGH TEMPERATURES EXPECTED TO REMAIN IN THE UPPER 90S AND LOW
100S ACROSS THE VALLEY THROUGH WEDNESDAY BEFORE A COOLDOWN
BEGINS THURSDAY. IT IS IMPERATIVE TO ENSURE ACCESS TO PROPER
COOLING, STAY HYDRATED, LIMIT OUTDOOR ACTIVITY, AND WEAR LIGHT
AND BREATHABLE CLOTHING IF YOU MUST BE OUTDOORS. TAKE EXTRA
PRECAUTION FOR VULNERABLE PEOPLE AND FOR ANIMALS AND CHECK IN ON
THOSE IN NEED.
THE GOOD NEWS IS THAT CLUSTERS CONTINUE TO BE IN UNUSUALLY
STRONG AGREEMENT THAT THE RIDGE WILL BREAK DOWN TO SOME DEGREE
LATER NEXT WEEK, THANKS TO A MINOR TROUGH THAT WILL FORM OFF
THE COAST. THIS SHOULD HELP US RETURN TO MORE REASONABLE
TEMPERATURES NEAR CLIMATOLOGICAL NORMALS, WITH TEMPERATURE
SPREADS BEING ABNORMALLY NARROW FOR A LONG-TERM FORECAST,
INDICATING GOOD CONFIDENCE IN THIS EVENTUALITY. THAT BEING SAID,
THE PROLONGED PERIOD OF HOT AND DRY CONDITIONS WILL CREATE
CONTINUED ELEVATED FIRE CONDITIONS, PARTICULARLY IN EASTERN KERN
AND TULARE COUNTIES, THOUGH ALL AREAS SHOULD EXERCISE CAUTION,
AS WE HAVE SEEN MANY FIRES ACROSS THE ENTIRE AREA RECENTLY,
SEVERAL OF WHICH HAVE PROMPTED EVACUATIONS. THIS FIRE RISK WILL
BE AUGMENTED BY THUNDERSTORM RISK IN THE SIERRA NEVADA EVERY
DAY, WHICH INCLUDES A RISK OF DRY LIGHTNING. WE SAW A LOT OF
LIGHTNING IN THE SIERRA NEVADA TODAY, AND THE STATIONARY NATURE
OF THESE STORMS ALSO LED TO SOME FLOODING CONCERNS. WHILE THE
WORST OF THE RAIN THANKFULLY AVOIDED BURN SCARS TODAY, THOSE IN
THE AREA SHOULD BE ON ALERT THE NEXT FEW DAYS, AS ANY PROLONGED
RAIN COULD POSE A FLOODING THREAT, PARTICULARLY OVER BURN SCARS.
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.
