Warmer than average temps continue over the next several days, then cooler over the weekend and early next week… 

Wednesday we expect areas of fog to start the day, then mostly cloudy skies will dominate for the remainder of the dayl. Highs will still reach the upper 70s to near 80° despite of the cloud cover, and then becoming cloudy overnight with isolated showers possible late at night.

Thursday we will be on the outer periphery of high pressure to our east, and scattered showers are likely as a mid-level disturbance moves in from the south around that high, which by then will be well offshore. Showers and perhaps a few rumbles of thunder continue Thursday night into early Friday AM, and then a cold front advances toward the region during the afternoon and evening that will likely bring another round of scattered showers/t-storms. To begin the weekend, clouds and a leftover shower may linger early Saturday before skies become partly cloudy, then partly to mostly sunny skies are expected Sunday through Tuesday with temperatures not too far from 70 degrees.
