AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN JOAQUIN VALLEY - HANFORD CA
518 PM PDT THU JUL 24 2014

.UPDATE...FOR AIR QUALITY SECTION

.SYNOPSIS...MOSTLY CLEAR SKIES OVER THE REGION AS HIGH PRESSURE
PREVAILS. A WARMING TREND WILL CONTINUE INTO THE WEEKEND.

&&

.DISCUSSION...UPPER HIGH PRESSURE OVER THE DESERT SOUTHWEST AND A
DRY SOUTHWEST FLOW ALOFT ARE PROVIDING OUR AREA WITH CLEAR SKIES
AND SEASONABLE TEMPERATURES TODAY. 12Z WRF INDICATES THE HIGH WILL
CONTINUE TO RETROGRADE WESTWARD ON FRIDAY AND SATURDAY RESULTING
IN A CONTINUED WARMING TREND ACROSS OUR AREA EACH DAY. BY
SATURDAY...AFTERNOON HIGHS ARE EXPECTED TO BE IN THE TRIPLE DIGITS
AGAIN OVER THE SAN JOAQUIN VALLEY AND SOUTHERN SIERRA FOOTHILLS AS
WELL AS OVER THE KERN COUNTY DESERTS.

THE 12Z WRF INDICATES THAT THE FLOW ALOFT WILL TURN TO THE SOUTH-
SOUTHEAST BY SUNDAY WHICH WILL ALLOW FOR INCREASED UPPER LEVEL
MOISTURE TO STREAM INTO OUR AREA. RH PROGS ARE NOT SHOWING MUCH IN
THE WAY OF MID LEVEL MOISTURE HOWEVER...SO ANY THUNDERSTORMS THE
POP UP ON SUNDAY AFTERNOON WILL BE CONFINED TO THE HIGHER
ELEVATIONS OF THE SOUTHERN SIERRA NEVADA.

MEDIUM RANGE MODELS ARE SHOWING LITTLE CHANGE IN THE PATTERN
THROUGH THE FIRST HALF OF NEXT WEEK. HIGH PRESSURE OVER THE DESERT
SOUTHWEST WILL CONTINUE TO BE OUR MAIN WEATHER FEATURE OF CONCERN.
TEMPERATURES WILL CONTINUE TO RUN ABOVE NORMAL AND SOME UPPER
LEVEL TROPICAL MOISTURE WILL STREAM NORTHWARD INTO OUR AREA ALONG
THE BACK SIDE OF THE HIGH AND PROVIDE FOR A SLIGHT CHANCE OF
DIURNAL THUNDERSTORMS EACH DAY THROUGH LATE NEXT WEEK OVER THE
HIGHER ELEVATIONS OF THE SOUTHERN SIERRA NEVADA.

&&

.AVIATION...VFR CONDITIONS CAN BE EXPECTED THROUGHOUT THE CENTRAL
CALIFORNIA INTERIOR DURING THE NEXT 24 HOURS.

&&

.AIR QUALITY ISSUES...
ON FRIDAY JULY 25 2014... UNHEALTHY FOR SENSITIVE GROUPS IN FRESNO
