Powered by NOAA / National Weather ServiceCos Cob School is a school in Cos Cob, Connecticut, part of Greenwich School District. The forecast above uses the school's own coordinates, so it reflects conditions at this campus rather than an average across the wider area.

Suburban districts depend heavily on bus fleets covering a wide area of residential streets, which are plowed after main roads. Side-street conditions at 5 AM often decide the call.
Connecticut averages about 40 inches of snow per year. Connecticut districts coordinate closures regionally and tend to close proactively for nor'easters.
We score the live forecast at this location against the factors that drive closure calls: snowfall total and intensity, when the heaviest accumulation lands relative to the morning commute, ice and freezing rain, wind chill, and how confident the forecast models are. You get a probability for a full closure, a two-hour delay, and an early dismissal.
This is an independent forecast, not an official announcement. Confirm any closure with Greenwich School District before acting on it.
