DISCUSSION
LAKE WIND ADVISORY CONTINUES FOR WEST SIDE COASTAL MOUNTAINS
NORTH OF 198 AND SAN LUIS RESERVOIR THROUGH 11 PM PDT MONDAY,
JULY 6TH. WEST WINDS OF 10 TO 15 MPH WITH GUSTS UP TO 30 MPH
WILL CREATE ROUGH WAVES DANGEROUS TO SMALL CRAFT AND DIFFICULT
DRIVING CONDITIONS, PARTICULARLY FOR HIGH-PROFILE VEHICLES.
MODELS ARE IN GOOD AGREEMENT THAT A RIDGE WILL START TO BUILD
OVER THE SOUTHWEST THIS WEEK. THIS WILL BE A SLOW BUT STEADY
PROCESS, AND AS SUCH, EXPECT TEMPERATURES TO CLIMB ACROSS THE
WEEK. ON MONDAY, VALLEY HIGH TEMPERATURES WILL BE IN THE MID TO
UPPER 90S AND INCREASE TO THE UPPER 90S TO MID 100S BY THE
COMING WEEKEND. DESERT HIGHS WILL START THE WEEK NEAR 100 AND
INCREASE TOWARD 110 OVER THE SAME PERIOD.
CONCURRENT WITH THE WARMING TREND WILL BE A DECREASE IN MINIMUM
RELATIVE HUMIDITIES, WITH VALLEY MIN RH AROUND 25% TO START THE
WEEK, DECREASING TO 13-17% BY FRIDAY. THE DESERT WILL START THE
WEEK WITH MIN RH VALUES OF 14-16%, DECREASING TO 4-8% LATER IN
THE WEEK. DAILY MAXIMUM WIND GUSTS ARE NOT EXPECTED TO EXCEED 12
MPH IN THE VALLEY DURING THE WEEK. HOWEVER, GUSTS ALONG THE
MOJAVE DESERT SLOPES MAY REACH 30-35 MPH EACH DAY AND 20-25 MPH
IN THE DESERT. THERE IS A 10-20% OF LIGHTNING ALONG THE SIERRA
CREST MONDAY. FIRE RISK WILL INCREASE DURING THE WEEK, PEAKING
ON WEDNESDAY, WHEN THE COMBINATION OF DRY AIR, HOT TEMPERATURES,
AND STRONG WINDS WILL CREATE SIGNIFICANT FIRE RISK IN EASTERN
KERN COUNTY.
THE INCREASING TEMPERATURES WILL CAUSE AN INCREASE IN HEAT
RISK, WITH MOST OF THE AREA UNDER MODERATE HEAT RISK BY FRIDAY,
WITH A FEW POCKETS OF MAJOR HEAT RISK.
AS THE HEAT CONTINUES, BE SURE TO TAKE APPROPRIATE PRECAUTIONS
AND CHECK IN ON AND MAKE ARRANGEMENTS FOR VULNERABLE PEOPLE AND
ANIMALS. BRACHYCEPHALIC (SHORT-NOSE) BREEDS WILL HAVE PARTICULAR
DIFFICULTIES WITH THE HEAT AND SHOULD BE KEPT INDOORS.
IF DRIVING OR BOATING IN AN AREA WITH A WIND ADVISORY, TAKE
APPROPRIATE PRECAUTIONS.
WATER TEMPERATURES ARE STILL IN THE UPPER 60S AND LOW 70S AND
MUCH COLDER NEAR WATER FLOWING FROM HIGHER ELEVATIONS. EXERCISE
COLD WATER SAFETY AT ALL TIMES.
