Rain showers delivered up to a half-inch of rain to the Sacramento region on Thursday, delivering much needed moisture to brown lawns and prompting pedestrians to shake the dust from long-dormant umbrellas.
The first good-sized rainstorm of the season delivered more than a third of an inch of rain to downtown Sacramento Thursday morning before heading to the suburbs -- and then into the foothills and mountains.
Rainfall totals as of noon.: 0.37 in Sacramento, 0.44 in Elk Grove, 0.32 in Rio Linda, 0.35 at Executive Airport, 0.51 in Loomis, 0.51 in Orangevale, 0.35 in Roseville, 0.63 in Auburn, 0.43 at Folsom Lake and 0.47 in Rancho Cordova.
Rain was falling in the Sierra Nevada where there is hope that the precipitation will help quell the still-burning King fire. Even if the rain is light over the 13-day-old wildland blaze, cooler temperatures and higher humidity will help the firefight.
The NWS issued a flash flood warning at 12:15 p.m. Thursday when Doppler radar indicated heavy rainfall over the King fire burned area. Flash floods and debris flows could occur until 6:15 p.m.
Behind the rain, a cold unstable air mass aloft is likely to produce some instability. Those conditions are favorable for thunderstorms developing Thursday afternoon and evening. Temperatures will stay well below normal with Sacramento’s high only expected to reach 75 degrees on Thursday.
The cool fall temperatures are expected to continue through Friday. Dry and warmer conditions are forecast for the weekend.
