Our run of sunshine will end this weekend when a storm system currently off the northern California coast will drop into the region. This is a good sized system and will impact much of the state and the Central Coast could see a good few days of rain Sunday through Tuesday, if not longer.
The calm before the storm continues through Saturday but clouds increase during the afternoon and evening and showers could start for the SLO county north coast as early as Saturday night but for most the rain starts Sunday morning.
Right now there is high confidence the system lingers into Tuesday at least. There is the possibility the storm could spin near us through Thursday. If that latter scenario happens the total rainfall could increase by an inch.
Right now the forecast is .75-2.5" but again there is the possibility it goes higher.
This is not a particularly windy system, but it is cold and thunderstorms are also possible and lower elevation snows as well (4500ft by Tuesday)
We'll have to keep an eye on rain rates. Sunday PM looks like the peak of the hardest rain, probably .75"/hr. or less so debris flow risk looks minor but areal flooding is possible during the peak.
Right now I am going with the chance of scattered showers Tuesday-Thursday. Temps take a big hit as well, highs in the 50s and lower 60s.
Next Friday looks dry with high pressure rebuilding for a warmer and dry following weekend.
