What a winter storm watch means
A winter storm watch gives early notice that conditions could meet winter storm warning criteria, usually 12 to 48 hours before the storm. Confidence in the track or precipitation type is not yet high enough for a warning. Watches are later upgraded to warnings, changed to advisories, or cancelled.
