claude-sonnet-4-6 Analysis · Mar 13, 2026
March 13 starts cold and sunny with near-freezing temperatures (30°F) that gradually warm through the afternoon, accompanied by increasing winds gusting up to 32 mph. A slight chance of light rain arrives late evening around 10–11 PM, but overall conditions are manageable for most drivers.
- 01 Early morning temperatures of 30°F create potential for black ice or frost on road surfaces, especially on bridges and overpasses, before roads warm up.
- 02 Wind gusts up to 32 mph (daytime) and 31 mph (overnight) may affect vehicle handling, particularly for high-profile vehicles.
- 03 A slight chance of light rain (20% probability) between 10 PM and 11 PM combined with temperatures in the low 40s poses a minor wet-road risk.
- 04 Temperatures remain near or below freezing (30°F) during the 7–8 AM window, increasing ice risk on untreated or shaded road sections.
- 05 Visibility data is not provided in the forecast, introducing some uncertainty about early morning fog or frost-related visibility conditions.
Morning safer driving window: 10:00 AM – 12:00 PM, once temperatures have risen above freezing (36–42°F) and roads have had time to thaw, while winds are still relatively moderate (5–10 mph). Evening safer driving window: 6:00 PM – 9:00 PM, before the slight rain chance arrives at 10 PM, with temperatures still in the mid-40s and precipitation probability below 10%. Avoid driving before 9:00 AM due to near-freezing road surfaces, and after 10:00 PM if light rain develops.
