March 5, 2026 brings persistent, heavy rain throughout the entire day and night with near-freezing temperatures (38–42°F), patchy to areas of fog, and increasing winds into the evening. Conditions pose significant hydroplaning, reduced visibility, and potential ice risk hazards for drivers.

• 01 All-day rain with near-certain precipitation probability (95–100%) from 6AM through midnight, with expected rainfall totals of 0.5 to 0.75 inches during the day and 0.75 to 1 inch overnight.

• 04 Evening and overnight winds increase to 8–13 mph with gusts up to 23 mph from the NE, adding crosswind hazards and making wet road conditions more treacherous.
• 05 Temperatures drop to near 38°F by 10–11PM with continued heavy rain (91–97% precipitation probability), raising the risk of freezing on elevated surfaces like bridges and overpasses overnight.
• 06 No active weather alerts were issued, but the combination of persistent rain, fog, near-freezing temps, and increasing gusts creates compounding hazards throughout the day.
