Today a very well developed low pressure system moved its way southwest towards the South California coast. This storm caused mass flooding, land slides, and tornadoes across much of middle and southern California. The south coast recieved almost a year’s worth of precipitation in only a matter of days. The pressure at the center of the storm was the equivalent of a category two hurricane. The storm only pushed moderate precipitation into parts of Northern California and Southern Oregon. This particular storm is now far enough away that it will no longer affect us.
After the storm passed, weak onshore flow pushed into the coastal areas bringing rain. Any rain that moved further east passed as light, isolated showers. Tomorrow will prove to be a better chance for shower activity. A warm front will move in early Monday morning and will push in shower activity before it passes. The heaviest rain will move in on Monday. Winds will become strong overnight Sunday into Monday. Snow levels with this storm will start to rise Monday after frontal passage, to around 6000′. This is where they will remain for most of the rest of the week. The best chance for rain/snow will be in the upper elevations of the Cascades and Siskiyous.
Tuesday will be a little drier with isolated shower activity at best. The next system will move in Tuesday night into Wednesday. This will be the heaviest rain this week. Winds will also increase at the coast and in the mountains. Despite the rain, these storms are moving fast and rainfall, while heavy, will last a few hours at best. Next weekend high pressure will build into the area giving us partly cloudy skies and mild temperatures.
