Summary
Although the hourly and daily forecast for 2026-02-21 shows mostly dry, mild conditions through the day and evening, a Severe Winter Storm Warning is active for the area on this date. Because the warning calls for heavy snow, whiteout potential, and very difficult to impossible travel, driving is not considered safely reliable today overall.

Key Factors
- 01 An active Winter Storm Warning is in effect beginning 2026-02-21 03:27 EST and lasting into 2026-02-22, with severe impact wording.
- 02 The alert warns of 8 to 16 inches of snow, snowfall rates over 2 inches per hour, blowing/drifting snow, and possible whiteout conditions.
- 03 The alert explicitly states travel could be very difficult to impossible.
- 04 Forecast data is inconsistent: hourly conditions show sunny/dry weather today, while the warning indicates major winter weather risk; this uncertainty lowers confidence and argues for caution.
- 05 Daily forecast stays dry through most of today, but conditions trend toward rain/snow chances overnight, so risk may worsen late tonight into early 2026-02-22.

Recommendation
Avoid non-essential driving today because of the active warning and conflicting forecast signals. If you must drive, the least risky morning window appears to be 10:00 AM-1:00 PM EST, and the least risky evening window appears to be 6:00 PM-9:00 PM EST, when the provided hourly forecast remains dry; avoid late-night travel and be prepared for rapidly worsening conditions.
