A sunny Sunday may give way to scattered thunderstorms and showers on Monday and into early Tuesday.
National Weather Service forecasters in Sacramento say thunderstorms could move into the Sacramento area sometime Monday afternoon before decreasing early Tuesday.
High temperatures were in the mid- to high 80s in Sacramento on Sunday. Downtown Sacramento was expected to top out at 87 degrees, with 85 degrees forcast for Sacramento Executive Airport.
Forecasters expect monsoonal moisture from southern California and the desert southwest to collide with a moist low pressure system out of the Gulf of Alaska, said Cindy Matthews, a forecaster with the National Weather Service in Sacramento.
Matthews said forecasters do not expect to see much rain out of Mondays system, but are concerned about potential lightning strikes.
The National Weather Service already has red flag warnings in effect for the far north state and the Sierra foothills east of Sacramento.
As dry as it is, the potential to cause fire starts is really there, Matthews said. The fuels are so dry that it doesnt take much.
