SYNOP:
High pressure aloft over the western states will continue near average temperatures through Friday. For Friday night into Saturday, a low pressure system will move inland with widespread wetting rainfall. Sunday will be mostly dry with the next period of wetting rainfall for late Sunday night and Monday with additional periods of precipitation through Wednesday

1. Late Friday Night/Saturday Morning System:
The storm system late Friday night and Saturday morning should bring a period of rain. Most rainfall will be around one-half (0.50″) inch west of the mountains and locally over one inch in the mountains. A brief period of heavy rain will be possible, with local one-hourly rainfall of over 0.25″, but overall the rain should not last long. The snow level will be around 6000′ with a few inches of snow above this elevation.

2. Storm Systems for Next Week:
Longer range model projections show a strong jet stream over much of the north Pacific with storm systems moving through California multiple times next week. Southwestern California will likely receive precipitation from some of these storms starting Monday and continuing most of the week (Sunday looks dry). Timing and precipitation amounts are still very uncertain though (so we are only including maps for this coming Friday night/Saturday morning). There is a chance of heavy rain at times and possible snow in the mountains. We will keep you informed!

NWS LAS VEGAS SYNOP– (NORTH & EAST OF COUNTY)
A weak disturbance will produce isolated showers over northern Lincoln County today then a ridge of high pressure will bring dry weather to the entire region Friday. An active weather pattern will begin Saturday as an upper low moves across southern California into Arizona followed by a parade of Pacific Storms which will impact most of the western states much of next week.

THIS DAY IN WEATHER HISTORY:
2017: A strong mountain wave produced an impressive wind gust of 107 mph at Burns Canyon (east side of San Bernardino Mountains).

2009: Santa Ana winds gusted up to 83 mph at Fremont Canyon. Winds downed trees and power lines, overturned semi-trucks, and damaged roofs.

2005: Five consecutive days of heavy rainfall started on 1/7 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.

2001: A very high tide and a four foot surf flooded Surfside in Seal Beach.

1998: Heavy rain that started on 1/8 and ended on 1/10 brought two inches of rainfall, causing floods and mud slides in Del Dios (near Escondido). A tornado hit Long Beach causing property damage. A waterspout was observed three miles off Laguna Beach.

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.

1949: The most significant snowstorm to hit lower elevations started on this day and ended on 1/11. 14 inches fell in Woodland Hills, eight inches in La Cañada and Catalina Island (at 2,100 feet), six inches in Altadena, five inches in Burbank, four inches in Pasadena, one inch in Laguna Beach and Long Beach. A trace fell in San Diego, the only time since 1882. Three feet piled up at Mt. Laguna, 18 inches fell on Cuyamaca, and one foot in Julian. Four to eight inches fell as low as 1000 feet in elevation. A light covering was reported in La Jolla, Point Loma, Miramar, Escondido, Spring Valley, and other outlying San Diego areas. The snow snarled all kinds of transportation and caused power outages and emergencies. A plane crash killed five and injured one near Julian. A camping group was stranded at Cuyamaca.

1948: It was 82° in Idyllwild, the highest temperature on record for January.

1888: Freezing temperatures in inland valleys killed the citrus crop.
