Clouds creep in tonight and deliver showers and cooler conditions tomorrow. We recover by Thursday and Friday with more sunshine, but a quick cold front delivers a crisp and dry weekend. Today (Election Day): Patchy frost is possible, especially in low-lying areas. Then sunny skies push temperatures into the middle to upper 60s — possibly 70 — in the afternoon. Light breezes are from the southwest at about 5 mph. Very low humidity makes for a comfortable, warm autumn day. Confidence: High Tonight: Clouds encroach overnight with a shot at showers toward dawn.
