What happened

The episode as NWS HNX wrote it up.

An upper-level ridge was over California at the start of November, creating a stable environment across the central California interior. Fresno tied its record high minimum temperature for the 2nd of 56 degrees, last set in 1941. Areas of fog developed in the central and southern San Joaquin Valley during the morning of November 3rd, but considerably less fog formed the next day.

The ridge remained over California through the 7th, then gave way to an approaching upper-level low. Light showers developed over the Tehachapi Mountains during the late morning of November 8th, as subtropical moisture moved into Kern County and collided with a cold front dropping south through the San Joaquin Valley. This set up a convergence zone over the Tehachapi Mountains that triggered the convection.

Heavy snow showers also occurred in the Southern Sierra Nevada, where up to one foot of new snow fell on November 8th. This was a significant impact to the mountain regions since quite a bit of mountain recreation was still going on at this time.

After this system moved through, As a result, the air remained moisture laden. A weak short-wave ridge moved over California during the night of November 8th-9th, but this was enough to trigger dense fog development over much of Kings County as well as southern Fresno and western Tulare Counties.

Thunderstorms developed during the afternoon of November 9th. One of these thunderstorms triggered a weak tornado (rated EF0), that touched down 4 miles north northeast of Tipton at 12:55 PM PST. No damage was reported. This was the 86th tornado to touch down in the WFO Hanford’s seven-county warning/forecast area since records began in the 1950’s, and was the 13th to touch down in Tulare County. Other thunderstorms dropped pea-sized hail on northern Hanford. In the Southern Sierra Nevada, several inches of snow fell above 6000 feet, and a couple of inches of snow fell on the floor of Yosemite Valley.

In the wake of this storm, an unseasonably cold airmass settled over the central California interior. Low temperatures fell below freezing across parts of the central and southern San Joaquin Valley on the morning of November 11th and 12th, and the Kern County deserts had their first hard freeze of the season.

AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE SAN JOAQUIN VALLEY - HANFORD CA
1040 AM PST THU NOV 8 2012

.SYNOPSIS...
A LOW PRESSURE SYSTEM WILL MOVE THROUGH THE AREA PRODUCING LIGHT
RAIN AND HIGHER ELEVATION SNOW TO CENTRAL CALIFORNIA. MUCH COLDER
AIR BEHIND THE SYSTEM RAISES CONCERNS ABOUT FROST CONDITIONS LATER
IN THE WEEKEND.

&&

.UPDATE...
SPRINKLES OR LIGHT SHOWERS ARE OCCURRING IN TEHACHAPI AT THIS TIME.
PUSH OF SUBTROPICAL MOISTURE OVER SOUTHERN CALIFORNIA MAY PRODUCE
ADDITIONAL LIGHT SHOWERS OVER THE TEHACHAPI MOUNTAINS AND THE
WESTERN KERN COUNTY DESERT. HAVE DONE A QUICK UPDATE TO ADD A CHANCE
OF SHOWERS IN THAT AREA.

&&

.DISCUSSION...
THE FIRST COLD FRONT IS MOVING THROUGH THE CENTRAL CALIFORNIA
INTERIOR THIS MORNING. AT 17Z /0900 PST/...CENTRAL AND SOUTHERN SAN
JOAQUIN VALLEY TEMPERATURES ARE DOWN 4-8 DEGREES /EXCEPT FOR THE
PORTERVILLE MUNICIPAL AIRPORT WHICH WAS DOWN 13 DEGREES/ AND A FEW
SITES WERE ALREADY REPORTING GUSTS OF 20-30 MPH. PRIMARY CONCERN
THIS MORNING IS WIND AND THE POTENTIAL FOR BLOWING DUST...ESPECIALLY
NEAR FALLOW OR RECENTLY PLOWED FIELDS.

GFS AND NAM MODEL GUIDANCE ARE IN GOOD AGREEMENT WITH NOT BRINGING
PRECIPITATION TO THE REGION UNTIL AFTER 00Z FRIDAY /1600 PST THIS
AFTERNOON/. PRECIPITATION WILL CONTINUE THROUGH FRIDAY NIGHT...WITH
MOS GUIDANCE FORECASTING THE HEAVIEST PRECIPITATION TONIGHT AND
FRIDAY MORNING. AS THE HEAVIEST PRECIPITATION IS FORECAST TO ARRIVE
BEFORE THE SECOND PUSH OF COLD AIR...DO NOT THINK THAT NEW SNOW
ACCUMULATIONS WILL NOT REACH WINTER WEATHER ADVISORY CRITERIA.

&&

.PREV DISCUSSION... /ISSUED 512 AM PST THU NOV 8 2012/

DISCUSSION...
A COLD LOW PRESSURE SYSTEM IS ROLLING SOUTHWARD TOWARD THE NORTHERN
CALIFORNIA COAST. AHEAD OF THE APPROACHING FRONTAL SYSTEM AN
IMPULSE MOVING ON SHORE IS BRINGING PRECIPITATION INTO THE
SOUTHERN CALIFORNIA COAST. AS THE SYSTEM CONTINUES TO DROP
SOUTHWARD AND PUSH THROUGH OUR AREA WE WILL SEE A SIGNIFICANT DROP
IN TEMPERATURES...DOWN TO A BIT BELOW NORMAL TODAY AND AS MUCH AS
10 TO 15 DEGREES BELOW NORMAL BY FRIDAY.

THE PRECIPITATION AREA TO THE SOUTH IS PROGGED TO STAY MAINLY
SOUTH...WITH JUST SLIGHT CHANCES OF BRUSHING KERN COUNTY. LITTLE
MOISTURE IS ASSOCIATED WITH THE INCOMING SYSTEM FROM THE NORTH AND
PRECIPITATION CHANCES AS THIS SYSTEM PUSHES THROUGH TODAY AND
TONIGHT WILL BE LIMITED AND MAINLY OVER THE FAVORED HIGHER TERRAIN
AREAS. STRONG GUSTY WINDS ARE EXPECTED TO BRIEFLY ACCOMPANY THE
PASSING SYSTEM AS IT BLOWS THROUGH TODAY...AND WITH LITTLE
PRECIPITATION EXPECTED THERE WILL LIKELY BE SOME BLOWING DUST IN
THE VALLEY AND DESERT AREAS. ALTHOUGH SNOW LEVELS WILL LOWER INTO
THE FOOTHILLS AS THE SYSTEM PUSHES THROUGH...WITH SCANT
PRECIPITATION EXPECTED...NO WINTER WEATHER PRODUCTS ARE
ANTICIPATED.

AS ADDITIONAL IMPULSES ROTATE THROUGH THE MAIN WEST COAST
TROUGH...PRECIPITATION CHANCES WILL CONTINUE INTO THE WEEKEND. THE
VERY COLD AIR ACCOMPANYING THE SYSTEM WILL BRING SOME FROSTY
TEMPERATURES TO THE VALLEY AND DESERT AREAS...WHERE MODELS SHOW
850 MB TEMPERATURES DROPPING BELOW 0 DEGREES C THROUGH THE
WEEKEND...THOUGH THE CLOUD COVER SHOULD HELP TO MITIGATE
TEMPERATURES A BIT.

AN UPPER LEVEL RIDGE IS PROGGED TO BEGIN BUILDING OVER THE WEST
COAST BY SUNDAY AS THE TROUGH MOVES OUT...BRINGING DRYER
CONDITIONS AND MORE SEASONABLE TEMPERATURES FOR EARLY NEXT WEEK
AHEAD OF ANOTHER TROUGH EXPECTED TO APPROACH OUR AREA BY MIDWEEK.
