claude-sonnet-4-6 Analysis · Mar 18, 2026
March 18, 2026 brings cold, mostly sunny conditions with temperatures ranging from 25°F in the morning to a high of 40°F in the afternoon. The primary driving concern is sub-freezing temperatures in the early morning hours, which raise the risk of ice on road surfaces.
- 01 Morning temperatures of 25°F (7–9 AM) are well below freezing, with wind chill values as low as 18°F, significantly increasing the risk of black ice or frost on roads and bridges.
- 02 Temperatures remain below freezing (under 32°F) until approximately 11 AM–12 PM, keeping ice risk elevated through mid-morning.
- 03 Afternoon temperatures rise to a high of 40°F with light winds (2–7 mph), making conditions much more favorable for driving.
- 04 Evening temperatures drop back to 33–37°F after 6 PM, approaching freezing again by late night (32°F by midnight), which could refreeze any moisture on road surfaces.
- 05 No precipitation is forecast for the day (probability near 0%), eliminating snow or freezing rain concerns.
- 06 Wind speeds are light throughout the day (2–7 mph), posing no significant crosswind hazard.
- 07 No active weather alerts are in effect for today.
Morning window: If you must drive early, wait until after 11:00 AM when temperatures climb closer to or above freezing, reducing ice risk. If driving before then (7–10 AM), allow extra stopping distance, brake gently, and use extra caution on bridges and overpasses. Evening window: Plan to drive between 5:00 PM and 7:00 PM, when temperatures are still in the upper 30s to 40°F and conditions are at their safest. Avoid driving after 9–10 PM as temperatures fall back toward freezing and ice risk increases again overnight.
