A storm system will bring increasing clouds with rain becoming likely tonight and Saturday. Showers will linger into Sunday, then a general warming and drying trend starts next week.
Models are showing subtropical moisture and showers developing as early as this evening and continuing off and on through Saturday morning. The cold front associated with the storm should pass thru the area Saturday morning into afternoon, which will then move south into Saturday evening.
I think it'll be mostly light rainfall rates (under .10"/hr) with totals of 0.25-1.00 inch across most of the area with some higher amounts possible along the northern SLO county coastline and at higher elevations.
There will be significant southerly to south-easterly at 15-30mpg which is marginal for a wind advisory, nearby counties have issued them. The winds associated with the storm are also whipping up large waves and a high surf advisory is in place.
Rain should taper off to showers sometime between Saturday night and Sunday.
The trough should clear out of the region on Monday and be replaced by an upper-level ridge of high pressure. Warming and drying should take place for early next week, there is some question about Wednesday with a trough quickly zipping thru the region but most models keep rainfall north of us. Stay tuned for updates on that.
