AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN JOAQUIN VALLEY - HANFORD CA
430 AM PST FRI DEC 11 2015

.SYNOPSIS...
A COLD STORM SYSTEM WILL CONTINUE TO MOVE THROUGH THE REGION TODAY
BRINGING PRECIPITATION AND GUSTY WINDS. AN UNSETTLED PATTERN WILL
CONTINUE INTO THE WEEKEND AS ANOTHER COLD STORM ARRIVES ON SUNDAY.

&&

.DISCUSSION...
A STRONG UPPER LEVEL JET IS IMPINGING ON CENTRAL/SOUTHERN CA AS IT
ROUNDS THE BOTTOM OF A PACIFIC TROUGH SWINGING INTO THE WEST
COAST. ANOTHER ROUND OF SHOWERS IS SPREADING SOUTHWARD ACROSS OUR
AREA AND A FEW LIGHTNING STRIKES WERE RECENTLY DETECTED AROUND
THE BAY AREA. SHORT TERM HIGH RESOLUTION MODELS SHOW THIS CURRENT
WAVE OF PRECIPITATION CONTINUING THROUGH THE MORNING HOURS WITH
SCATTERED SHOWERS LINGERING THROUGH THE AFTERNOON. THOUGH
PRECIPITATION IS FORECAST OVER THE MOUNTAINS THROUGH THE
AFTERNOON...THE BULK OF ADDITIONAL SNOW ACCUMULATIONS IS EXPECTED
THIS MORNING AND IT IS PLANNED AT THIS TIME TO LET THE WINTER
WEATHER HIGHLIGHTS EXPIRE ON SCHEDULE AT 7 AM. GIVEN THE RECENT
LIGHTNING TO OUR NORTH AND THE -30C COLD POOL ALOFT TO MOVE
OVERHEAD TODAY...A SLIGHT CHANCE FOR THUNDERSTORMS HAS BEEN ADDED
TO THE SAN JOAQUIN VALLEY FOR TODAY.

DENSE FOG IN THE SAN JOAQUIN VALLEY HAS BEEN MOSTLY MIXED OUT
WITH THIS NEXT PUSH OF PRECIPITATION AND THE DENSE FOG ADVISORY IS
ALLOWED TO EXPIRE. CURRENT MODERATELY STRONG WIND GUSTS IN THE
KERN COUNTY MOUNTAINS WILL INCREASE TODAY AND SPREAD INTO THE
DESERT AS THE TROUGH AND UPPER JET ENERGY SWING INLAND. A WIND
ADVISORY REMAINS IN EFFECT FOR THE KERN COUNTY MOUNTAINS AND ONE
HAS BEEN ISSUED FOR THE DESERT.

THERE WILL BE A BRIEF BREAK FROM THE UNSETTLED WEATHER
SATURDAY...BEFORE ANOTHER COLDER STORM SYSTEM DROPS INTO THE
REGION ON SUNDAY. MODELS ARE REASONABLY SIMILAR IN THEIR DEPICTION
OF THIS SYSTEM AS IT TAKES A SIMILAR TRAJECTORY BRINGING MORE
PRECIPITATION TO CENTRAL CALIFORNIA SUNDAY INTO MONDAY. ADDITIONAL
WINTER WEATHER PRODUCTS WILL POSSIBLY BE NEEDED FOR THIS PASSING
STORM. THE STORM WILL BRING COOLER TEMPERATURES...WITH TEMPERATURES
DROPPING SEVERAL DEGREES BELOW CLIMO FOR THE FIRST HALF OF THE
WEEK.
