Key Factors
- 01 Hourly precipitation chances remain 0–3% from 6 AM through midnight February 21.
- 02 Temperatures range from 34°F to 47°F during the day and remain about 37°F by midnight, limiting ice concern during today’s driving hours.
- 03 Winds are light, generally 1–6 mph.
- 04 A severe Winter Storm Warning is active in the alert feed, but its description states the heavy snow begins at 4 AM Sunday, February 22; it does not indicate hazardous snow during February 21.
- 05 From roughly 3–6 AM February 22, there is a 30% chance of rain and snow as temperatures approach 32–34°F, creating a developing late-night/early-morning slick-road risk.

Recommendation
Safer morning slot: 8 AM–12 PM EST, when skies are sunny/partly sunny, precipitation chances are near zero, and temperatures rise above freezing. Safer evening slot: 6 PM–10 PM EST, while precipitation chances remain zero and temperatures stay 39–44°F. Avoid nonessential travel after about 3 AM February 22 and be prepared to avoid travel Sunday onward because the Winter Storm Warning calls for heavy snow, strong gusts, and possible whiteout conditions.
