What to expect for rain in Northern California on Monday, rest of week

September is often a month with big changes as summer turns to fall, and this particular September is no different as off-and-on rain showers bring a flash flooding watch to nearby burn scars. More weather changes are ahead at the start of the work week for Northern California. “We are looking at some scattered showers in the forecast today, and maybe even some isolated thunderstorms for the afternoon,” meteorologist Eileen Javora said Monday morning. Monday morning commuters are looking at a wet drive. KCRA 3 is calling Monday a weather alert day since it is the first rain of the season and the morning commute could be slippery as folks hit the roads. There is also a slight chance of thunderstorms.Rain in Sacramento MondayA weather system spiraling off the coast is sending waves of rain to Northern California, with Monday being the best chance of rain around Sacramento and Stockton. A chance of thunderstorms pops up Monday as we get into the afternoon, Javora says. “As we get into the afternoon, we might see that flare-up of a few thunderstorms, especially around Sacramento and points westward,” she said. There are expected to be scattered showers in the morning throughout NorCal, but the Sierra will hang on to some light to moderate rain throughout the day. What we know about the rest of the weekTuesday is forecast to have partly cloudy skies again with a chance of a shower on Tuesday, with most of the activity in the Sierra.”As we get into Tuesday night and Wednesday, that is when the system finally pivots through. We might wake up to a few showers in the Valley but clearing is expected,” Javora said. By Thursday and Friday, we will see a warming trend with the possibility of hitting 90 by Saturday.Amounts of rain with this 3-day rain event look uncertain.

Rain in Sacramento Monday

A weather system spiraling off the coast is sending waves of rain to Northern California, with Monday being the best chance of rain around Sacramento and Stockton.

A chance of thunderstorms pops up Monday as we get into the afternoon, Javora says.

“As we get into the afternoon, we might see that flare-up of a few thunderstorms, especially around Sacramento and points westward,” she said.

There are expected to be scattered showers in the morning throughout NorCal, but the Sierra will hang on to some light to moderate rain throughout the day.

What we know about the rest of the week

Tuesday is forecast to have partly cloudy skies again with a chance of a shower on Tuesday, with most of the activity in the Sierra.

“As we get into Tuesday night and Wednesday, that is when the system finally pivots through. We might wake up to a few showers in the Valley but clearing is expected,” Javora said.
