A trough entered the region late Monday night, bringing patchy rain to the region beginning around midnight. In affected areas, rain continued into early Tuesday morning.

Precipitation totals ranged from as high as 0.45 inches in Fallbrook, to no measurable rain at all in Pinon Hills, Beaumont (Cherry Valley) and nearby areas. Fallbrook, Temecula, De Luz, and French Valley were among the wettest communities Tuesday morning. A total of 0.39 inches was reported in Temecula Valley's Wine Country (courtesy of Jim Sappington). WeatherCurrents' stations in Hemet and San Jacinto received fair totals of 0.22 inches and 0.18 inches, respectively (Lake Elsinore also tied with San Jacinto's total). A noticeable gap in precipitation bands visible on Doppler radar early Tuesday morning was present, mostly leaving a large portion of Orange County and extending northeast to near San Bernardino, with very little to no rainfall. This is consistent with the lack of measurable precipitation in Beaumont (Cherry Valley) as well as reports from WeatherCurrents contributors in East Highland (courtesy of Peter Michas) and Yucaipa (courtesy of Don Kramer) that not enough rain fell to register in rain gauges there. The lowest measurable totals were 0.02 inches in both Riverside (Orangecrest) and nearby Moreno Valley.

Mostly cloudy skies remained in the trough's wake Tuesday morning. A small chance of showers remained throughout the day Tuesday, before a high pressure ridge builds later in the week, bringing periods of weak offshore flow and warming. Another Pacific trough could bring chances of light precipitation Sunday night or Monday next week.

Here are the rain totals for the WeatherCurrents network and associates:
