California: Monsoon Moisture Feeding from the Gulf – USDA

WEATHER

Temperatures were once again hotter than normal this week, 70s-80s in the mountains with highs in the 70s to 90s along the coast from north to south, 80s-90s in the valley with even a few 100+ readings, and 100s-110s in the desert. Early in the week, even some mountain locations were over 90 degrees.

Nighttime lows were still quite warm for all locations except in the mountains, where temperatures dipped into the 30s-50s every night. Coastal locations reported lows in the 50s-70s from north to south, with 60s-70s in the valley, and 70s-80s in the deserts. Temperatures were slightly cooler by the weekend as a broad-scale trough began to dig into the western United States, dropping temperatures some 5 degrees.

Some locations received some light rainfall. The San Diego area received light showers on Tuesday totaling less than a tenth of an inch as a result of monsoon moisture feeding up from the Gulf of California. Locations in the northern valley and the northern mountains along a line from roughly Eureka to Redding and northward, received rain as a result of an upper-level low swinging into the Pacific Northwest. Rain totals up to half an inch fell Friday and Saturday, with the heaviest amounts in the mountains just to the north of Redding. Locations elsewhere in the State remained dry for at least the third week in a row.
