.DISCUSSION...
WINTER STORM WARNING OVER THE COASTAL RANGE ABOVE 3000 FEET HAS BEEN
ALLOWED TO EXPIRE THIS MORNING. SHOWERS HAD DIMINISHED BY 8 AM IN
THAT REGION ACCORDING TO DOPPLER RADAR. WILL LIKELY LET THE WINTER
STORM WARNING EXPIRE AT 10 AM FOR 3000 FEET AND ABOVE ACROSS WESTERN
PLUMAS COUNTY AND LASSEN PARK AREA AS SHOWERS ARE STARTING TO
DIMINISH...HOWEVER...ISOLATED TO SCATTERED CONVECTIVE SHOWERS WILL
CONTINUE INTO THE AFTERNOON AND MAY BRING AN ADDITIONAL FEW INCHES
OF SNOW. MEANWHILE...WIDESPREAD SHOWERS PERSIST ACROSS THE NORTHERN
SIERRA TODAY. WINTER STORM WARNING FOR THE NORTHERN SIERRA WILL
REMAIN IN EFFECT UNTIL THIS EVENING AS AN ADDITIONAL FOOT OF NEW
SNOW COULD ACCUMULATE ACROSS THE HIGHER TERRAIN.

SPOTTER FROM KINGVALE (6193 FT ELEVATION) CALLED AROUND 8 AM
REPORTING 15 INCHES OF NEW SNOW IN THE PAST 24 HOURS AND BRINGING
THEIR STORM TOTAL THUS FAR UP TO AROUND 77 INCHES. HE ALSO REPORTED
VERY POOR VISIBILITIES DUE TO BLOWING SNOW FROM THE WINDY
CONDITIONS. MOUNTAIN TRAVEL IS DANGEROUS DUE TO THE WEATHER
CONDITIONS AND MOTORISTS SHOULD CHECK WITH CALTRANS FOR LATEST ROAD
HAZARDS. DOWNED TREES...SPINOUTS...ROAD CLOSURES AND CHAIN
REQUIREMENTS HAVE ALREADY BEEN REPORTED FOR SOME ROUTES INCLUDING
HWY 20...I-80...AND HWY 50. WE WILL ISSUE A PUBLIC INFORMATION
STATEMENT AROUND 11 AM TO UPDATE THE PUBLIC WITH
REPORTS/OBSERVATIONS FOR THE PAST 24 HOURS INCLUDING SNOW AMOUNTS
FROM SKI RESORTS.

COLD FRONT IS CURRENTLY DRAPED ACROSS NORCAL AND WILL MOVE
SOUTHEASTWARD THROUGH THE DAY APPROACHING INTERSTATE 80 LATER THIS
MORNING/EARLY AFTERNOON. VALLEY SHOWERS HAVE GENERALLY ENDED IN
NORTHERN SACRAMENTO VALLEY AND HAVE SIGNIFICANTLY DIMINISHED IN THE
REST OF THE CENTRAL VALLEY. RAIN AMOUNTS IN THE PAST HOUR HAVE
MEASURED LESS THAN A TENTH OF AN INCH IN OUR VALLEY ZONES. ISOLATED
CONVECTIVE SHOWERS CONTINUE ALONG THE FOOTHILLS WILL LESSEN AS THE
FRONT MOVES SOUTHWARD.

120 KT JET STREAM ON THE BACK END OF THE TROUGH IS ALIGNED
NORTH-SOUTH OVER WESTERN CANADA DIVING TOWARDS NORCAL BRINGING MUCH
COLDER AIR INTO THE GOLDEN STATE LATER TONIGHT. AS CLOUDS SCATTER
OUT AFTER THE FRONTAL PASSAGE...THIS WILL ALLOW TEMPERATURES TO DROP
BELOW FREEZING ACROSS THE VALLEY FLOOR. FREEZE WARNING IN EFFECT FOR
THE OVERNIGHT HOURS THRU 10 AM WEDNESDAY. COLD AIRMASS WILL PERSIST
INTO THE THANKSGIVING HOLIDAY WITH ANOTHER FREEZE WARNING FOR WED
NIGHT INTO THURS MORNING. DAYTIME HIGHS WON'T PROVIDE MUCH RELIEF
FROM THE COLD WITH MAX TEMPERATURES HOVERING IN THE MID 40S ACROSS
THE VALLEY FOR WEDNESDAY...RAISING A LITTLE ON THURSDAY INTO THE
UPPER 40S/LOWER 50S.  JBB

.EXTENDED DISCUSSION (SATURDAY THROUGH TUESDAY)...
LONGWAVE TROUGH AXIS NEAR 125W WITH 120+ KT JET STREAM PLOWS DOWN
INTO THE TROUGH. THE ASSOCIATED SURFACE LOW IS FORECAST TO MOVE INTO
THE PAC NW...TRAILING A COLD FRONT S-SWWARD ACROSS NRN CAL. THE
ECMWF 500 MB TROUGH SHOULD PASS THROUGH THE FORECAST AREA BETWEEN
6-12Z SUNDAY (10PM-4AM SAT NIGHT INTO SUN MORN). THIS IS WHEN THE
MAJORITY OF THE PRECIPITATION SHOULD END. HOWEVER...SHOWER ACTIVITY
WILL CONTINUE AT LEAST OVER THE MOUNTAINS THROUGH SUNDAY. HPC AND WE
FAVOR AN ECMWF-BLEND. THE MODEL UNCERTAINTY IS FAIRLY SIGNIFICANT
THIS WEEKEND AS THE GFS TROUGH IS LESS AMPLIFIED AND MORE
PROGRESSIVE AS THE 500 MB TROUGH PASSES THROUGH NRN CAL SOME 12 HRS
PRIOR TO THE ECMWF. THE MODEL UNCERTAINTY CONTINUES INTO THE END OF
THE HOLIDAY WEEKEND AND INTO NEXT WEEK WITH THE ECMWF SHOWING COLD
NORTHEASTERLY FLOW ON THE BACKSIDE OF A LARGE TROF OVER THE GREAT
BASIN AND THE GFS SHOWING A MUCH FLATTER RIDGE. BOTH MODELS SHOW A
SURFACE HIGH IN THE GREAT BASIN SETTING UP A TRANS-SIERRA EASTERLY
WIND. THE STRENGTH OF THE HIGH WILL DETERMINE WIND SPEEDS AND TEMPS.
FOR THE TIME BEING WE HAVE TRENDED THE POPS ON TUE TOWARDS CLIMO TUE
AS THE NEXT TROUGH TRIES TO BREAK DOWN THE RIDGE.  JCLAPP

CONTINUE AHEAD OF SFC COLD FRONT THRU 19Z FOR THE CNTRL VALLEY.

Where: El Dorado County, 0.96 mi NNW of Latrobe to 2 mi NE of Latrobe
Rating: EF1
Path length: 1.99 mi

At approximately 1:17 pm an EF1 tornado developed near the town of Latrobe in El Dorado County, which is about four miles south of El Dorado Hills. The maximum wind speed of the tornado was estimated at 100 mph with a damage path of two miles. No injuries or fatalities have been reported. There was damage to the roof of one commercial building, a single power pole, a water tank, and to numerous trees.

Witness reports were crucial to the conclusion of the damage assessment as there was not a great deal of damage from which to distinguish between tornadic, downburst, or straight line winds. The conclusion of an EF1 designation was based primarily upon the damage caused to the oak trees in the damage path.

What these are
