Today will be a wet day across the Northern California. The weather system in the Pacific that was supposed to bring our best rain chances Thursday afternoon has sped up. We'll have isolated to scattered showers this afternoon with widespread rain tonight into tomorrow morning. The rain should mostly lean on the lighter side with no more than a quarter inch for most in the Valley. Northern Shasta county looks to pick up the most rain with 0.5 inches to an inch possible through Saturday.
Rain chances stick with us through Saturday. On Saturday the rain will begin to let us with only scattered to isolated showers through the day. Snow levels will also start high tonight at 8,000 feet but gradually lower to 4,000 feet by Saturday.
Sunday will be a sunny day across the area with no rain chances. The same will be seen for Monday. On Tuesday the forecast become a little more uncertain. I've put rain chances in the extended forecast for Tuesday due to the possibility of some disturbances moving through the area. However, its just as likely a strong ridge of high pressure will prevent these disturbances from moving in and keeping us dry. Will be watching this closely as it develops in the coming days.
Patchy fog could be seen in some areas this morning, depending on the location of any high clouds in the area around sunrise. The clearer the sky is above you, the better chance you have of seeing some light, patchy fog this morning. After the wet system moves through, widespread dense fog will be possible in the mornings to follow, Saturday-Monday, due to wet ground, clear night skies and very cold overnight lows expected to drop into the mid-30s for some in the Valley.
