The National Weather Service in Sacramento has issued a Fire Weather Watch for much of Northern California for Sunday-Monday, July 18-19.
Thunderstorms with Little Rainfall are expected to arrive late Sunday through Monday.
Monsoonal moisture moving up from the south will bring the potential for thunderstorms with little rainfall across portions of interior northern California late Sunday through Monday. Thunderstorms may develop Sunday afternoon over the Sierra south of I-80, then spread northward into portions of the Coastal Range, southern Cascades, and the northern Sierra north of I-80 overnight. Isolated thunderstorms may also develop in the Valley.
The best thunderstorm potential will be over the mountains. With the very dry fuels, any thunderstorm has the potential to ignite new fire starts.
