AccuWeather Forecast: Patchy drizzle near coast overnight
ABC7 Eyewitness News Weather Anchor Spencer Christian has your AccuWeather forecast.

Takeaway of the Day
Today began with a familiar pattern of patchy morning drizzle near the coast and a reinforced marine layer that lingered until midday near the coast and bay. With increasing sunshine this afternoon over the bay and inland, 3 p.m. temperatures were in the lower 60s at the coast, mid-70s near the bay, and upper 80s in the warmest inland communities. This temperature range is slightly below average for late August, mainly because of the cooling influence of a deepened marine layer-- which will expand across the bay and locally inland again tonight, bringing with it the likelihood of more patchy drizzle near the coast.

A Look Ahead
Tomorrow will be much like today, with morning clouds and coastal drizzle, followed by slightly below average afternoon temperatures. Highs will be mainly in the mid-60s at the coast, mid-to-upper 70s near the bay, and mid-80s to around 90 degrees inland. Wednesday and Thursday will bring a brief warmup, with temperatures rising into the upper 60s at the coast, upper 70s near the bay, and lower 90s inland. However, this will be only a two-day warmup, and an extended cooling trend will begin on Friday and continue into early next week.
