What happened

The episode as NWS STO wrote it up.

On January 17th, 2014, Governor Jerry Brown declared a drought emergency for the entire state of California. The drought continued through the year 2014 with well below normal precipitation, though there were brief periods of relief in February/March and December from heavy rains. Exceptional drought was reported by the U.S. Drought Monitor by the end of July for all of Interior Northern California, with the most impacted area being the Northern San Joaquin Valley.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SACRAMENTO CA
1040 PM PST Sun Nov 30 2014

.Synopsis...
Unsettled weather continues through the week with a continued threat
of precipitation. Lingering precipitation over portions of interior
Northern California overnight with snow levels around 6000 feet. A
wetter and warmer system will bring more precipitation Tuesday and
Wednesday.

&&

.Discussion...
Though the upper level trof has moved through Norcal...spotty WAA
precip is still occurring over Norcal as the Ern Pac ridge rebuilds
over the region ahead of the closed upper low near 140W. Moisture
will be trapped below the subsidence inversion on Mon so some light
rain/drizzle may occur at times... especially over the Nrn Valley
and mtns where there will be weak upslope flow.

Snow levels are AOA 6000 feet according to Dual-Pol radar data this
evening...but will be rising above 7 kft and the pass levels with
the next wx system Tue/Wed.   JHM

.Previous Discussion...

Precipitation spreads across the area again on Tuesday as an upper
level low approaches the California coast. The low is then expected
to move north along the Northern California coast on Wednesday
continuing the precipitation. This system is expected to be wetter
and warmer bringing snow levels at 7000 ft and higher and more
precipitation. Precipitable water values around an inch over
interior Northern California Tuesday afternoon into Wednesday and
over 1.5 inches off Southern California coast. Moisture is more than
normal so may see some high rainfall amounts with generally 1 to 2
inches possible in the Valley and generally 2 to 4 inches possible
in the mountains. Moderate to heavy snow at times with snow
accumulations up to 2 feet possible above 7500 ft. Also some
instability for a slight chance of thunderstorms which could bring
locally heavy rain. The current rains and rainfall from this system
along with possible periods of moderate to heavy rain could lead to
mud and debris flows over burn scars. Southeast to South winds will
be breezy and gusty...especially Wednesday afternoon and evening with
the low just off the coast.

.Extended Discussion (Thursday through Sunday)

Forecast remains uncertain for late week into the weekend as model
disagreement continues. Pattern looks to remain unsettled with
several weak waves riding east in weak flow. Nothing major or
well-organized at this point. Have continued with low chances for
showers for the end of the week with dry forecast for most of the
area by the weekend, outside far north. Daytime highs will be
around 60 in the valley and 40s-50s in the foothills/mountains.
Overnight lows will be in the mid 40s in the valley and 30s-40s in
the foothills/mountains. CEO

.Aviation...

Low pressure trough has moved through Northern California, with
warm frontal precip spreading over portions of interior Norcal.
Across the Valley, mostly VFR/MVFR conditions are expected the next
24 hours. Patchy IFR/LIFR fog may develop across portions of the
Valley after 10z-12z.

For the mountains, widespread IFR/LIFR conditions will continue into
Mon.

.STO Watches/Warnings/Advisories...None.

Impacts to the region included: Reservoirs dropped to low levels (record lows in some cases), farmers limited plantings of some crops and allowed areas of land to go fallow, increased agricultural unemployment and poverty, strong conservation efforts within many communities, increased reliance on shrinking groundwater resources, a decrease in snow-related tourism activity in the Northern Sierra Nevada, and a large increase in fire danger across the Northern Sierra Nevada, Southern Cascades and Coastal Range. Large wildfires such as the King Fire required large scale and very expensive suppression efforts. |For the entire state of California, 2014 was the warmest on record, which further increased the need for water and reduced an already limited snow pack. The Sierra snow pack ended the year at only about half of normal levels.|The California Department of Food and Agriculture’s Office of Public Relations summarized 2014 California agricultural losses: Direct costs to agriculture total $1.5 billion (revenue losses of $1 billion and $0.5 billion in additional pumping costs). This net revenue loss is about 3 percent of the state’s total agricultural value. The total statewide economic cost of the 2014 drought is $2.2 billion. The loss of 17,100 seasonal and part-time jobs related to agriculture represents 3.8 percent of farm unemployment. About 428,000 acres, or 5 percent, of irrigated cropland went out of production in the Central Valley, Central Coast and Southern California due to the drought.|The UC Davis Center for Watershed Sciences research suggests that northern interior California lost 4115 to 6796 agricultural jobs in 2014. Almond production dropped by 15 percent compared to the 2013. Almonds are the largest crop for the region.
