Temperatures are warming up slightly Tuesday everywhere but the South Coast, and still sitting a few degrees below average. The coast will be in the 60s to 70s and interior in the low 70s.
Heights are rising with a weak ridge of high pressure, helping the warmup. Skies will also be beautiful and mostly clear in the wake of Monday's cold front, which disrupted the marine layer from forming.
A trough is going to approach the region starting Tuesday night and lasting through Wednesday. It will bring back the marine layer and potentially some morning moisture to San Luis Obispo County as well. The trough will be followed by another weak ridge Wednesday night into Thursday.
Thursday is due to be the warmest day of the next seven with temperatures near normal. High clouds will ride the back of the ridge into the area, ahead of a series of troughs starting Friday.
Rain is expected to fall to the north of the region Friday and Saturday, but will start moving further south Sunday night into Monday, bringing our first more significant rainstorm of the season. Temperatures will continue to fall through the weekend.
