SYNOP:
A few light showers are possible for portions of Orange and southwestern San Bernardino Counties this morning, otherwise dry and warmer weather is expected through Thursday. A storm with the potential for more significant precipitation is possible for Friday night into Saturday with continuing chances for additional periods of precipitation through Monday

NWS LAS VEGAS SYNOP– (NORTH & EAST OF COUNTY)
Lingering showers will be possible this morning north of Las Vegas, over the southern Sierra, and the Arizona Strip. Strong, downslope winds over the Owens Valley and eastern slopes of the Sierra will decrease throughout the day. Locally dense fog is possible this morning across southern Nevada, northwest Arizona, and eastern San Bernardino County. Potential remains on Tuesday morning for patchy fog primarily across the southern Great Basin. Dry weather is expected for most areas Tuesday and Wednesday with temperatures
warming a few degrees each day. Isolated gusty, southwest winds will be possible today; especially across the western Mojave Desert where gusts up to 30 mph will be possible.

SPECIAL NOTES:
OUTLOOK FOR DES.18 TO MAR.19
• Slightly above normal temperatures this winter.
• Near normal number of offshore wind events expected through December.
• Near normal precipitation expected in December, but rain/snow possibly
decreasing in January.

• Large fire potential trending back to near normal early in December.

FUELS AND DROUGHT OUTLOOK
The widespread rain event of November 28th has altered the fuel landscape significantly in both the
short and long term. For 6 of the past 8 winters, fuels have been far drier than normal at the start of December, at least over Southern California. But this year, the combination of wet weather and short daylight hours should result in an efficient uptake of subsoil moisture by live vegetation. There will likely be a vast greenup of seasonal grasses over the next few weeks while native brush begins to show some growth.

Dead fuels will likely remain too wet to allow for ignition through at least the first half of the month. No periods of significant drying is expected anytime soon, so these fuels will not support large fire growth until a prolonged period of warm, dry weather occurs. Large fire potential will therefore fall to near normal over the next month and fire activity should remain at seasonally low levels (near zero) through at least January. A change to warmer and drier weather, should it occur, in the late winter into spring time period may lead to an earlier start to next year’s “fire season.” But until then, initial attack and resource demand should remain at seasonally low levels in December– in stark contrast to several of the last few years.

At the current time, much of the area remains in a D1 to D3 drought (the map on the left was produced prior to the storm of the 28th). Wet weather will likely go far to reducing the areas of extreme drought, but a D1 or perhaps a D2 drought may continue to occur over portions of the district the rest of the winter.
Snowpack this winter may be a bit lower than normal this year which may lead to lower reservoir storage heading into spring. But compared to last year, both the fire and hydrological situation in California is much improved.

DAILY FUELS/FIRE POTENTIAL:

SANTA ANA WILDFIRE THREAT INDEX: TODAY: GREY-NO RATING

NO RATING: Sundowner winds are either not expected, or will not contribute to
significant fire activity.

MARGINAL: Upon ignition, fires may grow rapidly.

MODERATE: Upon ignition, fires will grow rapidly and will be difficult to control.

HIGH: Upon ignition, fires will grow very rapidly, will burn intensely, and will be very difficult to control

EXTREME: Upon ignition, fires will have extreme growth, will burn very intensely, and will be uncontrollable.

THIS DAY IN WEATHER HISTORY:
2016: A strong, low latitude jet stream brought a series of storms through Southern California starting on 1/5 and ending on this day. Three-day rainfall totals were around two to seven inches for the coast, valley and foothill areas, and one to three inches for the deserts. After several years of drought, this was the only precipitation event of significance during an otherwise disappointing strong El Niño season. The mountains received a wide range of snow amounts, ranging from six to 30 inches, most of which fell above 5000 feet. The highest amounts were in the San Bernardino and Riverside County Mountains, with 20 to 30 inches in several locations. Strong thunderstorm winds damaged eight buildings and downed power lines in Vista. A building roof collapsed in Miramar and also at a horse stable in Bonsall. Many trees in Sabre Springs were snapped, some as thick as 18 inches. A tree in Poway fell on a car. Widespread flooding resulted from heavy rain, with southwestern San Diego County being hardest hit. Floods buried cars in Ocean Beach and Mission Valley. High water rescues occurred on this day around San Diego. Small mudslides, including boulders on highways were reported near Ramona, Redlands, Crestline, Orange, Rancho San Diego and De Luz. Three debris flows occurred in Silverado Canyon below a burn scar. Pea size hail fell in Orange County, Carlsbad and Poway. An airplane was struck by lightning on approach to San Diego airport on the morning of this day. A waterspout was observed off the coast at Cardiff on 1/6. A funnel cloud was sighted by several people in south San Clemente on this day. One house was damaged, but most likely from a wet microburst.

2012: Offshore winds began this day and ended on 1/8. Gusts reached 82 mph at Fremont Canyon, 74 mph in Crestline, 66 mph at Santiago Peak, and 60 mph at Ontario. Trees and power lines went down. Big rigs were overturned.

2007: Offshore winds started on 1/5 and continued peaking each morning until 1/8. Winds gusted to 84 mph at Fremont Canyon, 64 mph at Rancho Cucamonga, 63 mph at El Cariso, 62 mph at Rialto and 55 mph at Ontario. Downed power poles, tree limbs resulted. Trees fell on to homes and cars in Lake Arrowhead.

2005: Five consecutive days of heavy rainfall started on this day and ended on 1/11. The wet weather was blamed on an atmospheric phenomenon known as the “Pineapple Connection” or “Atmospheric River”. 31.75 inches fell in Lake Arrowhead, 29.70 inches at Lytle Creek, 19.86 inches in Devore, and 15.09 inches at Palomar Mountain. Four to ten inches fell at lower elevations. Flash flooding and mudslides caused millions of dollars of damage to homes, businesses, vehicles, parks, crops, roads and bridges. A state of emergency was declared in Riverside, Orange, San Bernardino,
and San Diego Counties. Widespread catastrophic floods impacted nearly every community. This followed heavy storms in late December and earlier in January.

2003: Very widespread Santa Ana winds blew on 1/6 and ended on this day. A gust of 100 mph was measured at Fremont Canyon, 90 mph in Ontario, 80 mph in Upland, 72 mph in Trabuco Canyon, 70 mph in Riverside, 58 mph at Miramar. Two died and 11 were injured. Widespread property damage resulted, as well as road closures, power outages, downed trees, wildfires and crop damage.

1993: A very wet series of storms that began on 1/6 and ended on 1/19 produced 20 to 50 inches of precipitation in the mountains and up to 12 inches at lower elevations over a two week period. It was one of the longest periods of consecutive days of rain on record (14) and measurable rain fell nearly every day from 1/2 to 1/19. Flooding and flash flooding, mud slides, etc., resulted.

1992: A storm that started on 1/5 and ended on this day brought one to two inches of rainfall to the lower elevations. Six to 20 inches of snow fell in the mountains and two to eight inches fell in the foothills and high desert floors. Flooding and mud slides resulted.

1986: Offshore winds peaked at 100 mph at Rialto and 90 mph at Laguna Peak (Venture Co.). Winds topped 60 mph near Mt. Laguna and up to 27 mph at San Diego. Three tractor trailer rigs overturned on I-8 at Buckman Springs Road, killing two. Another overturned rig in Ontario resulted in another death. Other accidents around Pomona occurred due to wind. Minor damage occurred in Santee.

1913: The coldest weather on record gripped San Diego County on 1/6 and on this day. In San Diego the morning low temperature on 1/6 was a record low 28° and the high temperature was an all-time record low maximum of 45°. On this day the low temperature was 25°, the lowest temperature on record. Other low temperatures on this day were 4° in Campo, 9° in Cuyamaca, 13° in Alpine, 15° in Julian and Lakeside, 20° in El Cajon, 22° in Lemon Grove, 24° in La Mesa, and 26° in Chula Vista. It was a killing freeze all over San Diego County and many crops and fruit were lost. Water pipes were frozen, trolley lines were disrupted and fishing nets were made unusable. There was ice skating in a San Diego fountain on ice 0.75 inch thick.
