Recommendation
Avoid driving today — a Blizzard Warning is active and travel is advised for emergencies only. If travel is absolutely unavoidable, the least-bad morning window is roughly 6:00–9:00 AM EST before heavy snow ramps up, and there is no safe evening window — conditions deteriorate sharply after 3 PM with heavy snow and blowing snow continuing past midnight. Postpone evening travel entirely.
