... Southwestern California weather summary for February 2015...

February 2015 was very dry across the region. Rainfall for the month
averaged 10 to 25 percent of normal for much of the forecast
area... except 50 to 80 percent of normal across much of San Luis
Obispo County.

It was a very warm February... with temperatures generally 3 to 7
degrees above normal... except more than 10 degrees above normal in
the mountains. In most locations... it was one of the warmest if not
warmest februaries on record. Tables indicating how this February
compared to the warmest February at selected stations follow the
climate data for the month.

Some of the more significant weather events of the month are listed
immediately below... followed by daily temperature and precipitation
records.

Upper level high pressure brought dry weather to the region from the
1st through the 5th. Temperatures were generally well above normal
in most areas... especially maximum temperatures. Highs were mostly
in the 70s on the coastal plain and in the Antelope Valley... and in
the mid 70s to mid 80s in the valleys. Highs at the coolest beaches
and in the mountains were mostly in the mid 60s to lower 70s during
this time.

On the 6th... southwesterly flow aloft ahead of an upper low off the
coast of the Pacific northwest began to transport some subtropical
moisture into the region. A band of rain pushed into San Luis Obispo
County during the late evening hours on the 6th. A band of heavy rain
affected northwestern San Luis Obispo County during the morning
hours on the 7th. Some rain spread into Santa Barbara and Ventura
counties on the 7th... while Los Angeles County received just some
occasional light rain.

After a slight lull late on the 7th... another upper level impulse
and associated surface front brought more rain to the region on the
8th... mainly to San Luis Obispo and Santa Barbara counties. Rain
ended in all areas by the evening hours on the 8th.

By far... rainfall totals from from these systems were highest across
northwestern San Luis Obispo County... with a sharp rainfall gradient
to the south and east. Some rainfall totals from late on the 6th
through the 8th included 6.85 inches at Rocky Butte... 4.33 inches at
upper Toro creek... 3.76 inches at Las Tablas... 2.44 inches at Black
Mountain... 2.36 inches at Santa Margarita... 2.17 inches at West Big

at la conchita... 0.30 inches in Lompoc... 0.27 inches in

Camarillo Airport... 0.15 inches in Pasadena... .0.12 inches in Agoura

in Woodland Hills... 0.04 inches at Van Nuys Airport... 0.03 inches in
Beverly Hills... and 0.02 inches at Burbank Airport and in downtown
Los Angeles.

As the upper low moved east of the region... warming took place on
the 9th... then very warm and dry weather persisted across the region
from the 10th through the 15th. High temperatures were mostly in the
upper 70s and 80s in coastal and valley areas... in the 70s in the
Antelope Valley and in the mid 60s to mid 70s at lower elevations in
the mountains. Some high temperatures during this stretch included
90 degrees at Fillmore on the 13th... 89 degrees Woodland Hills and
at Long Beach Airport on the 13th... at San Gabriel on the 12th... at
Hawthorne Airport on the 11th and 13th... 88 degrees in downtown Los
Angeles... at Northridge... in Pasadena... in Simi Valley and in the
city of Santa Barbara on the 13th... and at Lompoc on the 12th... and
87 degrees at Camarillo Airport on the 13th.

Gusty Santa Ana winds affected much of Los Angeles and Ventura
counties at times from the 10th through the 12th... with the peak of
the winds in most areas on the 11th. Some peak wind gusts included
62 mph at Wiley Ridge... 51 mph at Malibu Hills... in Saugus and at
Camarillo Airport... 48 mph at Mill Creek and at Warm Springs... 47
mph at chilao and at Newhall Pass... 46 mph at Camp Nine... 45 mph at
Topanga and at Boney Mountain... 40 mph at Oxnard Airport and at del
Valle... 38 mph at cheeseboro... and 36 mph at Point Mugu NAS.

A return to onshore flow and night through morning stratus brought
some cooling to coastal and valley areas on the 16th and 17th...
while warming occurred in the mountains and deserts on the 16th...
with some cooling there on the 17th. On the 18th and 19th...
temperatures were generally above normal in most areas... especially
so in the mountains and deserts.

Gradual cooling occurred across the region on the 20th and 21st.
Cooling was most pronounced west of the mountains as a deepening
marine layer and onshore flow cause night through morning low clouds
to push into most coastal and valley areas.

An upper level low developed over Nevada late on the 21st... and
then this system moved westward into California on the 22nd.
As this happened... a weak upper low off the coast of baja was pulled
northward into this system. Increasingly moist cyclonic flow and
instability caused some shower activity across much of the region on
the 22nd into the very early morning hours on the 23rd... with the
heaviest rainfall across Los Angeles and eastern Ventura counties.
Another impulse rotating into the region brought some additional
shower and isolated thunderstorm activity during the late morning
through early evening hours on the 23rd... especially to Ventura and
Los Angeles counties. There were many reports of small hail or
graupel that afternoon.

Showers ended in most areas by late evening on the 23rd. Some
rainfall totals from the 22nd through the 23rd included 3.15 inches
at Clear Creek... 2.86 inches at Mount Wilson... 2.80 inches at Camp
hi hill... 2.71 inches at opids Camp... .1.97 inches at San Gabriel

Saugus and in Los Alamos... 0.41 inches in Poppy Park and in Ojai...
0.39 inches at Lancaster Airport... 0.38 inches in South Gate and at
Palmdale Airport... 0.37 inches in Gaviota... at Acton... and at Van
Nuys Airport... 0.36 inches in Whittier and in Ventura... 0.34 inches
on the Carrizo Plain... 0.33 inches in Northridge... 0.32 inches at
Hawthorne Airport... at Paso Robles Airport... at the National Weather
Service in Oxnard... and at Camarillo Airport... 0.27 inches in Agoura
Hills... at Los Angeles Airport... and at Santa Barbara Airport... 0.24
inches at Long Beach Airport... 0.23 inches in Nipomo... 0.22 inches
at San Luis Obispo Airport... 0.21 inches in Thousand Oaks and in
Woodland Hills... 0.18 inches in Avalon... 0.17 inches in Cuyama and
at San Luis Obispo cal poly... 0.13 inches at la conchita... 0.07
inches at Santa Maria Airport... in Buellton... and in Solvang... 0.06
inches in Santa Ynez... and 0.05 inches in Carpinteria.

In the mountains... snow levels were mostly above 5500 feet... but
lowered occasionally down to 4500 feet. Some snowfall totals
included 7 to 10 inches at mountain high at 7000 feet... 6 to 10
inches at Wrightwood at 6000 feet... 2 inches at Mount Pinos at 8200
feet... and 1 inch at Pine Mountain Club at 6000 feet... at Mount
Wilson at 5700 feet... in Cuddy Valley at 5500 feet... and at Pinon
Pines at 5000 feet.

Dry weather with near normal temperatures returned to the region on
the 24th and persisted through the 26th. An upper low moving into
the Pacific northwest brought some cooling to the forecast area on
the 27th. This upper low dropped southward into Southern California
on the 28th... then wobbled slightly off the coast just west of
Monterey during the afternoon hours. Some light showers developed
across portions of Los Angeles County during the morning hours.
Shower and isolated thunderstorm activity associated with the upper
low moved into the region during the afternoon and evening hours.
Weather from this system will be detailed in the climate summary for
March.
