Key Factors
- 01 Freeze Warning/Frost Advisory in effect early morning, with frost possible until 8 AM and sub-freezing temperatures late tonight into early Tuesday
- 02 Temperatures start in the upper 30s to low 40s this morning, which can leave patches of frost on bridges, overpasses, and shaded roads
- 03 Slight chance of rain showers before 10 AM, though precipitation chances are low (around 15-19%)
- 04 Northwest wind increases to 10-12 mph with gusts up to 22 mph, which may affect higher-profile vehicles
- 05 No major heavy precipitation, snow, or ice is forecast during the daytime hours
Recommendation
If possible, avoid driving before 8 AM because of frost risk; the safer morning window is after 10 AM once temperatures rise and shower chances drop. For the evening, the safest window is roughly 6 PM to 10 PM, when precipitation is minimal and roads should be dry, though temperatures will be falling and the late-night freeze risk increases.
