After some patchy fog this morning, another warm and muggy day is ahead with temperatures topping out in the upper 80s. Increasing mixing and light east-northeast surface winds will make for fair smoke dispersal this afternoon. Otherwise, can`t completely rule out a spotty shower this afternoon mainly between 3pm to 7pm. However, confidence is low (<30%) in this occurring. .REST OF TODAY... Max temperature.....Around 87.
