A brief lull in the weather pattern is expected Thursday before the next system moves in on Friday with isolated to scattered showers and possibly light snow in the mountains. Warmer temperatures will return over the weekend

============================================================
THIS DAY IN WEATHER HISTORY:
2013: An area of low pressure moved in from the northwest, resulting in strong westerly winds through the passes and over the deserts. Winds gusted 40-50 mph on the floor of the Coachella Valley, with gusts up to 80-90 mph along the desert slopes. Damage to trees and structures, as well as blowing dust and sand, were reported in Borrego Springs and Palm Springs.

2001: Two funnel clouds were observed four miles southwest of San Diego – Lindbergh Field. Thunderstorms produced accumulations of hail up to one inch deep that caused travel chaos along Interstate 10 in Fontana and Interstate 8 in Alpine. In Fontana more than 100 cars were involved in a series of chain-reaction accidents. Near Alpine, 28 cars, two big rigs and a tour bus wrecked along a seven-mile stretch of Interstate 8.

1999: It was 19° in Palomar Mountain, the lowest temperature on record for April.

1975: The Padres’ home game against the San Francisco Giants was rained out at (then) San Diego Stadium. This also occurred the previous day on 4/8.

1974: Strong winds in the deserts and coastal areas downed power lines, overturned numerous small craft in the rough seas between San Diego and the Channel Islands, and damaged a freighter at L.A. Harbor. In Palm Springs, wind gusts to 60 mph overturned a trailer at a construction site and caused roof damage to many homes.

1965: A cold late-season storm that started on 4/7 and ended on 4/11 brought heavy rainfall and snowfall to the region. Over the period 7.66 inches of precipitation fell in Lake Arrowhead (with nearly 50 inches of new snow). 5.44 inches fell in Palomar Mountain (with 13 inches of snow), 4.36 inches in Big Bear Lake, 4.25 inches at Cuyamaca, and 3.14 inches in Idyllwild (with 24 inches of snow). 1.5 to 2 inches of rain fell across the coastal basin. Mountain roads were closed.
