Key Factors
- 01 Winter Storm Warning is in effect from 3:27AM through 6PM Monday (Feb 22), but hourly forecast for Feb 21 daytime shows 0-3% precipitation chance and sunny/mostly sunny skies
- 02 Temperatures stay above freezing (34-47F) for nearly all of Feb 21 daytime, reducing ice risk
- 03 Winds are light (1-6 mph) all day, no significant crosswind or gust concerns noted in hourly data
- 04 Late evening (after 11PM) shows temps dropping to 37F with a slight rise in precipitation chance (3%), and overnight into Feb 22 brings a chance of rain/snow mix with the storm intensifying
- 05 Discrepancy exists between the severe Winter Storm Warning headline and the relatively benign hourly forecast shown for Feb 21 daytime - this warning is primarily aimed at Feb 21 night into Feb 22

Recommendation
Morning driving is safe between 6AM-11AM with sunny skies and light winds. Evening driving is also safe between 5PM-9PM while conditions remain dry and mostly cloudy. However, monitor conditions closely after 11PM tonight and into Feb 22, as the Winter Storm Warning indicates heavy snow (8-16 inches) and gusts to 40 mph are expected to develop, making the overnight/early Monday commute hazardous - avoid driving after midnight if snow arrives.
