AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN JOAQUIN VALLEY - HANFORD CA
235 AM PDT FRI JUL 3 2015

.SYNOPSIS...
WARM AND MUGGY CONDITIONS WITH SCATTERED SHOWERS AND THUNDERSTORMS
WILL CONTINUE IN THE CENTRAL CALIFORNIA INTERIOR THROUGH TODAY AS
MONSOONAL MOISTURE FLOWS INTO THE REGION. SCATTERED AFTERNOON AND
EVENING THUNDERSTORMS WILL CONTINUE OVER THE HIGH COUNTRY OF THE
SOUTHERN SIERRA NEVADA THROUGH THE WEEKEND. TEMPERATURES WILL REMAIN
NEAR TO ABOVE AVERAGE DURING THE NEXT FEW DAYS.

&&

.DISCUSSION...
MONSOONAL MOISTURE BROUGHT MORE SHOWERS AND THUNDERSTORMS TO
INTERIOR CENTRAL CALIFORNIA THURSDAY. FRESNO HAD A SECOND DAY OF
RECORD-SETTING RAINFALL AND AFTER ONLY TWO DAYS IS TIED FOR THE 6TH
WETTEST JULY ON RECORD...WITH JULY 1896. THE WETTEST JULY AT FRESNO
IS JULY 1913 WITH 0.33 INCH.

THE LOWER LEVELS OF THE ATMOSPHERE HAVE FINALLY BEGUN TO MOISTEN AND
ALLOW RAINFALL TO REACH THE GROUND. THUNDERSTORMS BROUGHT LOCALLY
HEAVY RAINFALL AMOUNTS TO THE SOUTHERN SIERRA NEVADA OVER THE LAST
24 HOURS WITH AMOUNTS INCLUDING 1.21 INCH AT WOLVERTON POINT...0.96
INCH AT HAPPY ISLES IN YOSEMITE NATIONAL PARK... 0.45 INCH AT
LODGEPOLE IN SEQUOIA NATIONAL PARK...AND 0.23 INCH AT CALIFORNIA
CITY. OTHERWISE RAINFALL AMOUNTS WERE MAINLY LESS THAN 0.20 INCH.

THE CLOUD COVER CONTINUED TO KEEP NIGHTS WARM. FRESNO TIED ITS
RECORD HIGH MINIMUM TEMPERATURE FOR JULY 2ND OF 78 DEGREES
/LAST SET IN 2013/...WHILE BAKERSFIELD MISSED ITS RECORD BY ONLY TWO
DEGREES /81 VS 83 IN 2013/.

A FEW NOCTURNAL THUNDERSTORMS CONTINUED ALONG THE SOUTHERN SIERRA
NEVADA CREST EARLY THIS MORNING. NWS DOPPLER RADAR ALSO INDICATED A
SHOWER THAT MOVED ACROSS KINGS COUNTY INTO WESTERN FRESNO COUNTY
WHICH HAD DROPPED MEASURABLE RAIN AT N.A.S. LEMOORE. A THUNDERSTORM
ALSO MOVED INTO TUOLUMNE MEADOWS IN YOSEMITE NATIONAL PARK SHORTLY
AFTER 09Z /0200 PDT/ THIS MORNING.

THE MAIN WEATHER FEATURE THIS MORNING IS THE UPPER-LEVEL LOW
SOUTHWEST OF POINT CONCEPTION. THE CIRCULATION AROUND THE LOW IS
ENTRAINING MOISTURE WRAPPING AROUND A FOUR-CORNERS RIDGE AND PULLING
THIS MOISTURE INTO CALIFORNIA. THUNDERSTORMS COULD DEVELOP AGAIN
TODAY OVER THE KERN COUNTY MOUNTAINS AND DESERT...AND WITH THE
SOUTHEAST FLOW ALOFT COULD DRIFT INTO THE SOUTH END OF THE SAN
JOAQUIN VALLEY. DO NOT EXPECT FRESNO/S RAINFALL RECORD FOR TODAY OF
0.14 INCH IN 1925 TO BE THREATENED...BUT BAKERSFIELD COULD TIE...OR
BREAK...ITS RECORD FOR TODAY OF A TRACE...ALSO SET IN 1925.

THE MODELS ARE IN GENERAL AGREEMENT WITH THE LOW LIFTING NORTHWARD
OVER THE NEXT 24 HOURS...TURNING THE FLOW ALOFT OVER CALIFORNIA MORE
SOUTHERLY AND KEEPING THE MONSOONAL MOISTURE MAINLY OVER THE
SOUTHERN SIERRA NEVADA BEGINNING SATURDAY.

BY SUNDAY...THE LOW IS FORECAST TO BE WEST OF MONTEREY AND CREATING
A SOUTHWEST FLOW ALOFT OVER THE CENTRAL CALIFORNIA INTERIOR. THIS
WILL ADVECT DRIER AIR INTO CENTRAL CALIFORNIA AND REDUCE THE RISK OF
THUNDERSTORMS OVER THE MOUNTAINS. THE DRIER AIRMASS ALSO WILL BRING
CLEARER SKIES TO THE REGION...ALLOWING FOR COOLER NIGHTS AND MORE
SEASONAL DAYTIME HIGHS FOR NEXT WEEK.

&&

.AVIATION...
SCATTERED THUNDERSTORMS WITH AREAS OF MVFR CEILINGS CAN
BE EXPECTED IN THE SOUTHERN AND CENTRAL SIERRA NEVADA AND KERN
COUNTY MOUNTAINS AND DESERT THROUGH THE EARLY EVENING HOURS.
OTHERWISE...VFR CONDITIONS WILL PREVAIL ELSEWHERE THROUGHOUT THE
CENTRAL CALIFORNIA INTERIOR DURING THE NEXT 24 HOURS.

&&

.AIR QUALITY ISSUES...
ON FRIDAY JULY 3 2015... UNHEALTHY FOR SENSITIVE GROUPS IN FRESNO
AND KERN COUNTIES.
