DISCUSSION
THE UPPER-LEVEL RIDGE CURRENTLY CENTERED JUST OFF THE WEST
COAST WILL BUILD INLAND OVER THE REGION STARTING WEDNESDAY.
HIGH TEMPERATURES WILL CLIMB WELL INTO THE 90S IN MUCH OF THE
LOWER ELEVATION LOCATIONS ON WEDNESDAY AND WILL WARM FURTHER ON
THURSDAY. IN FACT, CHANCES FOR TRIPLE DIGIT HEAT RISE TO 70-80
PERCENT BY THURSDAY ACROSS THE CENTRAL VALLEY AND 90 TO NEAR 100
PERCENT IN THE KERN COUNTY DESERT. SIMILAR TEMPERATURES
CONTINUE INTO THE WEEKEND. LOW MINIMUM HUMIDITY (8-18 PERCENT) WILL
COINCIDE WITH THE HOTTER TEMPERATURES, ESPECIALLY BY THURSDAY.
OVERNIGHT LOWS WILL ALSO RISE A BIT, BUT SOME OVERNIGHT RELIEF
WILL BE FELT IN MOST OF THE SAN JOAQUIN VALLEY AS LOWS DIP
MAINLY INTO THE 60S. HOWEVER, THE LARGER URBAN AREAS, SUCH AS
BAKERSFIELD AND FRESNO, THE KERN COUNTY DESERT, AND THE THERMAL
BELT IN THE SIERRA FOOTHILLS AND LOWER COASTAL RANGES WILL
REMAIN IN THE LOWER TO MID 70S EACH MORNING INTO THE WEEKEND.
LITTLE RELIEF IN TEMPERATURES WILL OCCUR EVEN INTO EARLY NEXT
WEEK. THE CHANCES FOR A TRIPLE DIGIT READING REMAIN AT 30-40
PERCENT ON MONDAY AND NEXT TUESDAY, AT LEAST IN THE SAN JOAQUIN
VALLEY. OTHERWISE, THE CHANCES ARE STILL 65-75 PERCENT ACROSS
THE DESERT. LONGER RANGE GUIDANCE SUGGESTS A WEAKENING IN THE
RIDGE BY THE MIDDLE OF NEXT WEEK, WITH SOME LOWERING OF
TEMPERATURES. HOWEVER, CHANCES (ROUGHLY 50 PERCENT) FOR ABOVE
AVERAGE TEMERATURES CONTINUE FOR AT LEAST THE 6-10 DAY PERIOD,
PER CPC. FOR THE 8-14 DAY PERIOD, CPC SHOWS TEMPERATURES
