AccuWeather Forecast: Cooler pattern begins tomorrow
ABC7 Eyewitness News Weather Anchor Spencer Christian has your AccuWeather forecast.

Takeaway of the Day
Our mid-week warmup peaked today. The marine layer is compressed, it's shallower than earlier this week, and the result is more rapid daytime warming. At 3 p.m., temperatures were in the lower-to-mid-60s at the coast, mid-70s near the bay, and lower 90s inland. However, the marine layer will begin deepening again tonight, which will produce widespread early morning clouds and patchy drizzle, and perhaps a few damp spots on our roadways for morning commuters.

A Look Ahead
A cooler pattern begins tomorrow, as afternoon highs near the bay and inland will be about 3 to 5 degrees lower than today's highs. A deeper marine layer will retreat more slowly tomorrow, which of course means a shorter period of sunny skies and warming. Highs will be in the lower 60s at the coast, lower-to-mid-70s near the bay, and mainly lower-to-mid-80s inland. This pattern will remain rather steady through the weekend and into early next week.
