Recommendation
Drive today and complete any essential trips before nightfall. Best morning window: 9:00AM-12:00PM. Best evening window: 5:00PM-8:00PM. Avoid travel after about 11:00PM tonight as rain/snow begins near freezing, and postpone Sunday/Monday trips given the heavy snow warning; keep a flashlight, food, and water in your vehicle and check 511 for road conditions.
