AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN JOAQUIN VALLEY - HANFORD CA
200 PM PDT SUN AUG 30 2015

.SYNOPSIS...DRY WEATHER CAN BE EXPECTED OVER THE CENTRAL
CALIFORNIA INTERIOR FOR THE NEXT SEVERAL DAYS. TEMPERATURES ARE
EXPECTED TO REMAIN BELOW AVERAGE THIS UPCOMING WEEK AS ONSHORE
FLOW PREVAILS. GUSTY WINDS CAN BE EXPECTED IN THE KERN COUNTY
MOUNTAINS AND DESERT EACH AFTERNOON AND EVENING.

&&

.DISCUSSION...A COLD FRONT WHICH PUSHED THROUGH CENTRAL CA
OVERNIGHT BROUGHT A PERIOD OF GUSTY WINDS ALONG WITH A NOTICABLE
COOLING TREND TO OUR AREA TODAY WITH TEMPERATURES GENERALLY
RUNNING 5-10 DEG F BELOW YDAY. SOME HIGH CLOUDS ASSOCIATED WITH
THE FRONT REMAIN OVER THE SOUTHERN HALF OF OUR CWFA THIS AFTERNOON
WHILE AREAS FROM FRESNO COUNTY NORTHWARD HAVE CLEARED OUT.

12Z WRF IS INDICATING THAT THE WESTERN CONUS WILL REMAIN IN A
TROUGHY PATTERN FOR THE NEXT FEW DAYS. SOME RECOVERY IN
TEMPERATURES ARE ANTICIPATED ON MONDAY AND TUESDAY AS HEIGHTS AND
DIURNAL THICKNESSES RISE AND THE PREVAILING AIRMASS WARMS. THE
TROUGH IS THEN PROGGED TO AMPLIFY ON WEDNESDAY...BRINGING A
REINFORCING SHOT OF COOLER AIR INTO OUR AREA.

THE MEDIUM RANGE MODELS ARE NOW INDICATING THAT THE WESTERN CONUS
TROUGH LINGERS OVER CA THROUGH FRIDAY WITH A DRY WESTERLY FLOW
PREVAILING OVER CENTRAL CA. TEMPERATURES WILL RECOVER A BIT EACH
DAY...BUT REMAIN SLIGHTLY BELOW SEASONAL NORMALS AT LEAST THROUGH
THE END OF THE WEEK. THE TROUGH IS PROGGED TO EJECT EASTWARD NEXT
WEEKEND AS HIGH PRESSURE BUILDS INLAND. THIS WILL BRING A MORE
PRONOUNCED WARMING TREND FOR THE HOLIDAY WEEKEND AHEAD. RH PROGS
CONTINUE TO SHOW LITTLE TO NO SIGNS OF ANY SIGNIFICANT MOISTURE
IMPACTING OUR AREA THROUGH NEXT WEEKEND. THEREFORE...OUR FORECAST
REMAINS DRY THROUGH THE FIRST WEEK OF SEPTEMBER.
