The storm followed additional unsettled weather which brought patchy drizzle to the region on Saturday. Light rain arrived to parts of the region late Monday night, however most communities received rain Tuesday morning, while cloudy weather remained for the remainder of the day. The bulk of the storm's precipitation focused on San Diego County and surrounding areas, with both WeatherCurrents stations in Simi Valley and Pinon Hills to the north being missed entirely. Where rain did fall, storm totals ranged from 0.04 inches in Temecula Valley's Wine Country (courtesy of Jim Sappington) to 0.23 inches in East Hemet. In Riverside's Canyon Crest neighborhood, a total of 0.08 inches was recorded (courtesy of Jim Ness). Much warmer, drier weather followed from Wednesday onwards as an upper level ridge ... http://weathercurrents.com/sanbernardino//NewsItemDisplay.do?Id=1674 A weak Pacific storm travelled across California on Tuesday, however the storm lost almost all of its energy and moisture as it approached Southern California - leaving nearly all of the region with little to no measurable rain at all. While precipitation totals were already expected to be light across Southern California, the storm rapidly fell apart south of Point Conception, leaving even areas that anticipated higher rain totals, with little or no precipitation at all. In the WeatherCurrents network, only Simi Valley recorded measurable precipitation through Wednesday morning - a total of only 0.02 inches. Further north in the state, the National Weather Service confirmed three weak tornadoes in Fresno County (the strongest of which was rated EF-1 on the Enhanced Fujita Scale, indicating peak gusts between 86 and 110 miles per hour), causing minor damage and no injuries. This convection had dissipated entirely before reaching Southern California. A low pressure system over Ce ... http://weathercurrents.com/sanbernardino//NewsItemDisplay.do?Id=1673 A cold late-season storm, originating in the Gulf of Alaska, will travel south down the state Tuesday into Wednesday. For Los Angeles County and northwards, the storm is projected to bring the potential for thunderstorms and brief heavy precipitation - however, rain chances drop significantly for areas south and east of Los Angeles as current model projections depict the storm weakening as it approaches Orange, San Bernardino, Riverside and San Diego counties. Strong southwest to west winds are forecast for the mountains and deserts Tuesday night into Wednesday morning. Precipitation totals for the inland valleys and coasts are predicted to be around 0.1 inch. Another storm is forecast to bring additional light precipitation and winds to the region next weekend. http://weathercurrents.com/sanbernardino//NewsItemDisplay.do?Id=1672 A weak late-season Pacific storm brought showers to the region last week, providing another reprise from the anomalous heat the region has been experiencing since the beginning of March. Precipitation totals were fairly consistent, averaging around 0.2 inches across the majority of WeatherCurrents stations. Simi Valley led the WeatherCurrents stations with 0.57 inches, while the driest total belonged to Pinon Hills with 0.05 inches. In Temecula Valley's Wine Country, a notable total of 0.68 inches was reported (courtesy of Jim Sappington), while in Riverside's Canyon Crest neighborhood, 0.21 inches was reported (courtesy of Jim Ness). The storm offered some relief from the warm, dry conditions that have dominated the region since March. Here are the rain totals for the WeatherCurrents network and associates: Location Storm Season Source Temecula Valley Wine Country 0.6 ... http://weathercurrents.com/sanbernardino//NewsItemDisplay.do?Id=1671 Cloudy skies and a deep marine layer loomed over Southern California on Tuesday, as a weak low pressure system finally brings relief from the anomalous heat that had gripped the region for the entirety of March. Precipitation from this storm is expected to be light, and more concentrated over mountain and foothill areas. At the time of this writing, WeatherCurrents stations in Pinon Hills, Riverside (Canyon Crest) and Simi Valley had recorded measurable precipitation. Totals are forecast to reach no more than 0.10 inches across the valleys and coasts through Wednesday, while up to 0.25 inches is possible in the mountains. Snow levels will hover around 7000-7500 feet above sea level Wednesday morning, as the storm quickly departs the region to the east. Cool temperatures, about 3-5 degrees below average for this time of year, will continue through Thursday before offshore flow develops for Friday and Saturday.
