The low pressure area to the south off of central California is rotating an area of moisture northwestward towards the area this evening that brings a chance of showers to us later tonight along with a slight chance of thunderstorms through tomorrow morning, then we see another thunderstorm threat persist with daytime heating tomorrow with the lingering instability. The thunderstorm threat ends but we keep the chance of showers lingering tomorrow night into Friday morning when, thanks to the low to the south weakening and moving inland, even the shower threat diminishes.
By Saturday we are watching another low pressure area developing in the Gulf of Alaska that is moving southeastward, bringing a slight chance of showers by the afternoon Saturday with showers likely Saturday, and a series of systems keeps rain and rainshowers in the forecast for Sunday into Monday with a chance still on Tuesday.
So, that is the big picture, and here is the forecast – cloudy with that chance of showers today, then add a slight chance of thunderstorms after midnight. These could give is a brief period of moderate to heavy rain and gusty winds as they move through, and hail is possible in the thunderstorms also, otherwise we have westerly winds 4-8 diminishing, lows near 46.
Cloudy with that chance of showers and possible thunderstorms again tomorrow, winds becoming westerly 4-8, highs near 55, the thunderstorm threat ends tomorrow night and the showers become more scattered, west winds 4-8 still, lows near 45.
Look for mostly cloudy skies Friday with the shower threat ending by the afternoon, winds westerly 5-10, highs near 52, then mostly cloudy but dry Friday night, lows near 42.
A slight shower threat returns in the afternoon Saturday with the threat increasing that night, highs near 55, lows near 41, then rain and rainshowers are likely Sunday, breezy also, with more showers likely into Monday, highs near 55, the low Monday night drops to near 39.
Tuesday the shower activity becomes more scattered, and the afternoon high temperature rises to near 58.
