Friday looks like a partly cloudy day (after more extensive morning clouds in wind protected valleys). Winds will pick up in the afternoon at 15-25mph out of the NW. Temps will be in the low to mid-60s at the coast with lower 70s inland.
Saturday will be a day of transition. Clouds increase into the afternoon when a few scattered showers are possible but a better chance of rain is Saturday night into Sunday.
Some showers possible Saturday afternoon but best timing for moderate rains is Saturday later PM into Sunday AM.
This system is looking better on the latest modeling with .10-75″ possible with some isolated spots reaching the 1+” territory. Snow levels around 5000ft. This is interesting to be talking about significant rain this late in the season and mountain snows. Average rain for the month of May in San Luis Obiso is only .43″, and we got there with yesterday’s system alone. The record is more than 4″, which we will probably fall shy of.
A lot of questions about the weekend storm and potential rainfall. Today it looked good on the modeling from .10-75″
There is a slight chance of thunderstorms with the Saturday-Sunday rain. The instability aloft could keep some activity going into Sunday PM. Monday looks partly cloudy.
Another storm is possible Tuesday-Wednesday of next week.
The Tuesday-Wednesday system does look to produce rain, but probably more showery rather than intense. This looks to be another snow-maker for the CA mountains.
Models are trending to the main impact of this system heading north with showers for the Central Coast. This will be yet another snow-maker for CA mountains. This system needs to be watched because a track change could could put significant rain on the Central Coast but right now it looks like .10-40″ potential is a better bet. This outlook is certain to be adjusted as the system draws closer.
