Key Factors
- 01 Freeze Warning is active from 12:00 AM to 9:00 AM EDT (sub-freezing temperatures as low as 26°F), creating a risk of icy or refrozen road surfaces early this morning.
- 02 Hourly forecast shows temperatures 38–40°F from 7–9 AM and a slight chance of rain showers (about 15–19% PoP) around 7–10 AM, which can contribute to slick patches if any surfaces were frozen.
- 03 Gusts may reach as high as 22 mph during the day (NW wind 2–12 mph with gusts), which can reduce stability for high-profile vehicles and increase crosswind effects.
- 04 Precipitation chances are low later today (near 0–10% in evening/overnight), and evening temperatures are above freezing (low-to-mid 40s), reducing ice risk after the morning warm-up.

Recommendation
Safer driving windows today: Morning: after the Freeze Warning ends at 9:00 AM EDT (best after 10:00 AM when the slight chance of rain showers is lowest). Evening: 6:00 PM–9:00 PM EDT (mostly clear/partly cloudy with temps ~48–45°F and PoP ~0–6%).
