The weather service's Hanford office said dangerous thunderstorms and small hail are possible north of Kern County on Tuesday from 2 p.m. The Sacramento weather service office warned of a 10% to 25% chance of thunderstorms across the northern Central Valley through Thursday. Afternoon highs across the Bay Area will be below normal, in the high 50s to low 60s, through the week. Rain chances continue through Thursday, the weather service said. In the Bay Area, the weather service said rain showers are on tap Monday night into Tuesday and an organized rain band is expected to push through the region Tuesday morning. #CAwx #CAwater /IFdDLgEyxM- Daniel Swain April 30, 2023 A late-season cut-off low, associated with rather cold air aloft, will bring a period of much cooler and unsettled weather to most of CA. High-elevation snow, continued showers, below-normal temperatures, and thunderstorms are all in the mix for California this week.Īfter a substantial early-season warm spell across interior CA, another big change in the pattern is still on track. While this is not a strong storm and it will not bring the copious amounts of snow and rain that winter systems delivered earlier this year, 'it will bring atmospheric conditions unstable enough for fairly widespread convective showers and isolated to scattered thunderstorms at times, with some light high mountain snowfall,' UCLA climate scientist Daniel Swain wrote in a Tweet on Sunday.

on Monday, the city had hit 57 degrees - that's a 31-degree temperature difference. On Friday, downtown Sacramento hit a high of 88 degrees at 2 p.m. 'When you consider how warm it was late last week, it's a pretty dramatic shift.' 'I suppose it is a winter storm in that we're going see snow, but it would be a very late-season storm,' said Katrina Hand, a forecaster with the weather service's Sacramento office. The shift in the weather was triggered by a trough of low pressure from the Gulf of Alaska pushing into California and pulling in cold air and unsettled weather, the National Weather Service said.
