Ridge strengthens Tuesday into Wednesday with a low moving down the coast Thursday with some welcome light  precipitation arriving Thursday evening. Light to moderate precipitation expected Friday will give some much needed moisture for the forest with cooler temperatures. Lingering cloud and some showers are likely Saturday, with an unsettled day expected Sunday. Ridge rebuilds for Monday with seasonable temperatures. Guesstimates: No precipitation before Thursday, trace-2 mm by Friday am, 10-15+ mm by Saturday am, trace-1 mm by Sunday am, 0-trace by Monday am.
