Heaviest Rain Yet to Come

Showers will persist tonight with a chance for isolated thunderstorms; after midnight shower activity will become more light and isolated and the thunderstorm threat will diminish. Thursday will bring mainly isolated shower activity for inland areas with scattered showers at the coast and Cascades. Snow levels will drop to 3,500 feet by Thursday morning which means roads will likely be snow covered over highways 230 and 140 and potentially some snow over Siskiyou Summit. You can check the tripcheck website for road conditions on the weather homepage under ‘Weather Links.’

Friday the cold air mass will move out and a sub-tropical connection will be made bringing in higher snow levels and more moisture. The heaviest rain will fall along the coast and in the coastal mountains potentially 3 to 4 inches and the coast and up to 6 inches in some spots in the coastal mountains. This has the potential to cause river and stream rises and localized flooding. Rain will increase through the day Friday for inland areas and will be moderate at times with greatest rain totals falling in the mountains for inland areas. Showers will taper off Saturday and we’ll bring in a chance for isolated thunderstorms Saturday afternoon across the region, with most thunderstorm activity occurring at the coast.

Showers move south into northern California Saturday with all areas seeing decreasing showers through the day but if thunderstorms develop they can produce heavy rain, gusty winds and small hail. Showers on Sunday will be light and isolated with another cold front bringing increasing showers on Monday.

Thanks for logging on and have a great evening!
