Key Factors
- 01 No active weather alerts for the day.
- 02 Dry forecast with precipitation chances 0-2% through the day and evening.
- 03 Light winds generally around 2-7 mph, so no significant crosswind concern.
- 04 Morning temperatures start around 25-31°F, which is below freezing and could increase risk on untreated bridges or shaded roads.
- 05 Best overall road-weather conditions occur from afternoon into early evening as temperatures rise to about 37-40°F under sunny or mostly sunny skies.
- 06 Late evening temperatures fall back toward 32°F, so any residual moisture could refreeze, though no precipitation is forecast.
