SYNOP: (NWS SAN DIEGO)
A low pressure system tracking across Baja today into tonight will bring a return of onshore flow which will spread cooling and higher coastal humidity inland. It will also bring increasing clouds with a chance of showers extending northward into portions of San Diego County for this afternoon and evening. For tonight and Wednesday, a cold low pressure system from the north will bring increasing chances for showers with wetting rainfall along with a slight chance for thunderstorms on Wednesday. Periods of showers will continue into Thursday and could linger into early Friday. A weak low pressure system from the northwest could bring a few showers for late Friday into early Saturday. Drier and a little warmer for Sunday.

Last rainfall was late September (tropical remnants) –Last winter storm was mid May 2019

Polar upper low (cold) drops south and merges with tropical remantmoisture and old upper low (which gave us hot weather Sunday-Monday)

Showers and thunderstorms develop Tuesday afternoon and evening
Heaviest rainfall on Wednesday as cold air sweeps in (upper low center)

Moist west to northwest flow behind departing closed low that tracks over California bight and Riverside County keep showers going Wednesday night and Thursday

Rainfall of 0.50 to 1.50 inches most locations coast, mountains, valleys, foothills Locally 2 inches of rainfall –rates of 0.25 to 0.60 per hour Less amounts northern Orange County and lowest Coachella Valley

Snowfall –1 to 3 inches above 5500 feet and 3 to 6 inches above 6500 feet with up to 10 inches at 7500 feet –heaviest on Wednesday.
Cold morning low temperatures on Thursday and Friday

NWS LAS VEGAS SYNOP– (NORTH & EAST OF COUNTY)
A major pattern change will bring much needed wetting rains to the region as well as high elevation snows tonight. Higher elevation snow amounts could be significant as well which should significantly improve the fuel situations in those places. Lower elevation areas will be dependent on how much rain occurs this week, but expecting enough rainfall activity to result in at least short term fuel improvement for much of the region. Drier conditions expected to return by the weekend.

DAILY FUELS/FIRE POTENTIAL:
Large fire potential will be lower after today due to much higher RH, cooler temperatures and wetting rains over Southern CA. But the rainfall expected will be showery/convective in nature, meaning some locations will receive substantial precipitation while nearby areas may receive very little. Furthermore, the central coast will see little, if any, rainfall this week. While the rainfall will lower fire potential and cause a recovery of dead fuel moisture in a few locations, the vast majority of the district will see fuels dry back out and be susceptible to ignition when drier weather arrives once again next week.

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:
2008: Santa Ana winds blew from 11/15 to this d ay. Winds gusted over 70 mph in the Santa Ana Mountains and over 60 mph in the northern Inland Empire. The Freeway Complex Fire burned from Corona through Chino Hills and Yorba Linda. This fire destroyed or damaged over 300 homes and four businesses. More than 30,000 acres burned and more than 40,000 evacuated.

1967: A moist subtropical storm system produced 14+ inches of rainfall in the mountains above LA, and 7.96 inches in LA. On this day 1.87 inches fell in one hour in LA, the greatest one hour rainfall on record. Flooding was called the “worst since 1934.” Two were killed. Flash flooding and mud slides resulted. 400 were stranded in the mountains due to closed highways.

1964: After a major snowstorm, arctic air covered the region. It was -15° (that’s right, below zero!) in Big Bear Lake, the lowest temperature on record for November, the third lowest temperature on record, and the earliest date in the season to record a temperature below zero. This is likely the lowest temperature ever recorded in Southern California. It was 10° in Idyllwild, the lowest temperature on record for November. This also occurred on 11/17/1958. It was 8° in Victorville, the lowest temperature on record for November.

1963: Heavy rains hit Southern California with 1.5 to three inches on this day and on 11/20. Six were injured in local flooding and numerous traffic accidents. Strong storm winds downed hundreds of trees and power lines.
