Odds of any steadier rain with this system are highest this evening and tonight. ADThrough tonight: Showers move through in a few waves. The heaviest rain should stay to our south, but a tenth of an inch to a quarter of an inch is possible locally. With humidity on the rise, and some more moisture around from showers, fog should be more widespread than last night. South winds are pretty light, blowing around 5 mph.
