DISCUSSION
A HEAT ADVISORY IS IN EFFECT FOR THE MAJORITY OF THE AREA FROM
11 AM THURSDAY UNTIL 11 PM SATURDAY.
THE MAJORITY OF THE AREA IS UNDER A MODERATE HEAT RISK, WITH
SOME AREAS UNDER A MAJOR HEAT RISK, INCLUDING FRESNO ON FRIDAY.
TAKE APPROPRIATE PRECAUTIONS NOW BY REDUCING OUTDOOR ACTIVITY,
HAVING COOLING AND HYDRATION AVAILABLE, AND HAVING A PLAN FOR
VULNERABLE PEOPLE AND ANIMALS.
A LARGE RIDGE OFF THE WEST COAST WILL CONTINUE TO BUILD AND
SLOWLY MIGRATE EASTWARD OVER THE NEXT FEW DAYS, BRINGING WITH IT
STEADILY INCREASING TEMPERATURES. THERE IS A 40-70% CHANCE OF
EXCEEDING 95 DEGREES ACROSS MOST OF THE VALLEY TODAY. THURSDAY
HAS A 50-80% CHANCE OF VALLEY AREAS REACHING 100 DEGREES, AND
FRIDAY HAS A 60-90% CHANCE OF VALLEY AREAS REACHING 100 DEGREES.
SIMILAR TEMPERATURES WILL CONTINUE INTO THE WEEKEND. LOW
MINIMUM RELATIVE HUMIDITIES (8-18 PERCENT) WILL CREATE INCREASED
FIRE RISK BEGINNING FRIDAY AND CONTINUING THROUGH THE WEEKEND
FOR EASTERN KERN AND TULARE COUNTIES. INCREASING OVERNIGHT LOWS
WILL CREATE A CUMULATIVE EFFECT IN REGARDS TO HEAT RISK, AS
VALLEY LOWS ARE EXPECTED TO INCREASE FROM THE MID 60S TO AROUND
70 BY THE WEEKEND, EXCEPT IN URBAN AREAS, LIKE FRESNO AND
BAKERSFIELD, THE THERMAL BELT, AND THE KERN COUNTY DESERT,
WHERE THEY WILL BE A FEW DEGREES WARMER.
THE HEAT CONTINUES INTO NEXT WEEK, WITH A 30-40% CHANCE OF
TEMPERATURES REACHING 100 DEGREES IN THE VALLEY ON MONDAY.
CURRENT MEDIUM-RANGE GUIDANCE SUGGESTS THE RIDGE WEAKENING IN
THE MIDDLE OF NEXT WEEK, WHICH WILL HELP TO COOL TEMPERATURES A
BIT.
DESPITE THE HEAT, WATER IS STILL RUNNING COLD AND POSES A RISK
TO SWIMMERS, BOTH HUMAN AND ANIMAL. PRACTICE SAFETY AROUND
LAKES, RIVERS, AND STREAMS.
