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

Takeaway of the Day
Despite the presence of a deep marine layer this morning, along with areas of drizzle, the afternoon turned out to be relatively mild. As of 3 p.m., temperatures were in the mid-60s at the coast, mid-to-upper 70s near the bay, and mid-to-upper 80s inland. This range is below average for mid-August, but certainly pleasant and mild. Of course, the marine layer will deepen and expand again tonight -- bringing with it more patchy drizzle, which will likely continue into the early morning commute.

A Look Ahead
We can expect a brief warming trend tomorrow and Wednesday, with high temperatures approaching 80 degrees around the bay and lower 90s inland. This will be a brief two-day warmup, as a gradual cooling trend will develop on Thursday and continue into the weekend.
