Sacramento, Calif., (May 9, 2017) – A broad ridging pattern over the western United States brought dry and hot weather to the State during the first two thirds of the week. Then a pattern shift over the weekend brought cooler temperatures and precipitation to parts of the State.
A few isolated showers were limited to the Los Angeles basin and the far northern mountains near Mt. Shasta with low amounts of precipitation. Saturday saw more widespread rains in a band from the Los Angeles basin northward through the southern valley into the central and northern Sierras. The heaviest precipitation on Saturday exceeded one inch and fell in the Sierras near Lake Tahoe, with most other areas north and south along the band limited to a quarter inch of precipitation. On Sunday, light scattered precipitation fell on the central/southern Sierras, southern valley, and southward to the San Diego area. Warm temperatures resulted in substantial snowmelt in the mountains during the week, with only about six inches of snow cover remaining at the 6,500 foot elevation level in the southern Sierras. Upwards of four feet still exist over 6,500 feet in the central Sierras, with over eight feet in the northern mountains over 5,500 feet.
Temperature highs were in the 60s to 80s in the mountains, 70s to 80s along the coast, 80s to 90s in the valley, and 80s to 100s in the desert. The temperature lows were in the 30s to 50s in the mountains, 50s to 60s in the valley and along the coast, and 50s to 70s in the desert.

Some irrigated oats were being cut and dried. Corn continued to be planted, and earlier planted fields were growing well. Warm and sunny weather allowed resumption of field work and planting throughout most of the state.
