Key Factors
- 01 A Winter Storm Warning is active (through Feb 22 4:00AM EST) citing heavy snow and gusts up to 40 mph, but the hourly/daily forecast for Feb 21 shows no snow and only 0-3% precipitation probability
- 02 Mostly sunny to partly sunny skies all day with no precipitation expected during daytime hours
- 03 Light winds of 2-6 mph, well below any crosswind hazard threshold
- 04 Temperatures above freezing (35-47F) during the day reduce ice risk; early morning near 34-35F warrants minor caution for any residual icy spots
- 05 A slight chance of rain/snow appears late, after midnight (around 3-4AM Feb 22), with overnight temps dropping toward 32-34F
- 06 Apparent discrepancy between the severe alert and the benign hourly/daily forecast lowers confidence; conditions could change

Recommendation
Driving is generally safe today. Best morning window is roughly 9:00AM-11:00AM EST once temperatures warm to 40-43F and any overnight ice melts. Best evening window is around 4:00PM-6:00PM EST while skies remain clear and winds are calm (2 mph); avoid late-night travel after midnight when rain/snow may begin and temperatures fall near freezing. Verify current road conditions (dial 511) given the active Winter Storm Warning.
