SOUTHERN CALIFORNIA GEOGRAPHICAL AREA COORDINATION CENTER

RIVERSIDE, CALIFORNIA

A low pressure area passed directly over Southern California early this morning, triggering scattered showers and a few wet thunderstorms. Around 130 lightning strikes were recorded in the foothills and the south slopes of the Angeles and San Bernardino N.F. where some small hail occurred as well. A dusting of light snow was seen over 5,000 feet. In general, precipitation totals were around a quarter inch in Central California with a few reports up to a half inch near the higher terrain. This system will continue to push eastward this morning, but some showers will continue through noon, mainly across eastern San Diego and Imperial Counties. Partly cloudy, but cool weather will continue through Saturday. Gusty north winds of 15-25 mph with gusts to 35 mph will be possible along the I-5 Corridor and Santa Barbara County tonight. Similar wind speeds may be possible in these areas Saturday night. Across the Sierras and in Mono County, strong west winds over 50 mph will be possible tonight and Saturday as another system moves into the Great Basin. Rain will be likely Saturday in Central California from Monterey and Fresno Counties northward. Additional precipitation across Central California Saturday looks to be under a quarter of an inch from this system with 2-4 inches of snow in the mountains above 5,000 feet. Early next week, the flow will turn weakly offshore which will lead to warmer and drier weather. Look for an extended period of light offshore flow during the night and morning hours next Monday through Wednesday. Wind speeds will generally be under 30 mph, but some higher gusts may be possible from Orange County southward early Tuesday morning. Temperatures will climb back into the lower 80s in the valleys of Southern California by next Tuesday and Wednesday with RH likely dropping into the teens. Poor RH recovery is expected over Southern California next Monday through Wednesday. No precipitation is expected next week, but another storm may reach the state the following weekend. END/RK
