A low-pressure system off the Pacific coast will bring cooler temperatures to the Sacramento region, according to the National Weather Service.
For today, the high temperature is expected to hover around 87 degrees. Overnight lows will touch 59 degrees. The cooling trend will be in play through Thursday.
"The system will bring a southwesterly flow and continue the Delta breeze," said Drew Peterson, a forecaster with the National Weather Service in Sacramento. "We will be up to five degrees cooler than normal."
Meanwhile, the Rim fire burning in Tuolumne County has entered Yosemite National Park. However, the smoke from that blaze is unlikely to venture into the Sacramento region. Peterson said Lake Tahoe and Reno will bear the brunt of the smoke.
