Key Factors
- 01 NWS Special Weather Statement notes fog developed early this morning; some areas may become locally dense with visibility of a quarter mile or less and rapidly changing visibility.
- 02 The alert’s guidance specifically recommends slowing down, using low-beam headlights, and leaving extra space if dense fog is encountered.
- 03 Hourly forecasts from 7:00 AM onward show partly sunny conditions with 0% precipitation and no mention of fog in the hourly narrative, but high relative humidity earlier in the morning suggests lingering haze/fog is possible.
- 04 Temperatures stay well above freezing throughout the day (roughly 67–82°F), so there’s no indication of ice from freezing rain/snow.

Recommendation
If possible, avoid driving during the early-morning fog risk and choose a later morning window such as 10:00 AM–12:00 PM. For the evening commute, driving should generally be fine—consider 6:00 PM–8:00 PM, when precipitation chances are very low (0–2%) and winds are light (about 7–8 mph).
