There is a shower and thunderstorm chance for some Tuesday

A cold upper-level low has cut off from the jet stream and will spin over the Central Coast Tuesday before kicking out.

Due to upper-level instability and daytime heating, some showers and a slight chance of thunderstorms exists for Tuesday.  The low is lacking some available moisture to work with so it is no slam dunk.  I think the best chances for showers/thunderstorms are inland and at higher elevations in the afternoon and early evening when instability is at its peak.  Even if it rains the totals look to stay less than .30" where it rains (outside of thunderstorms where isolated higher totals can’t be ruled out).  Regardless it looks to be a minor threat and no evacuations are expected in recent burn areas.  I think most of the west-facing coastal valleys and beaches should miss out on rain.

Temps will stay on the cool side Tuesday but high pressure builds in slowly Wednesday for a much warmer forecast Thursday through Sunday.  Inland temps will rocket into the mid-80s with coastal and beach temps well into the 70s.

The ridge will weaken next Monday but mild weather remains through much of next week.
