Real-time probability that schools in Annapolis, Maryland will be cancelled tomorrow, based on live forecast data and local closure thresholds.
It's 74°F — no snow day expected.
Typical closure threshold
2–5 inches of accumulation
Annapolis has one of the lowest snow-closure thresholds of any region in the country. Districts here close for events that would be a non-story in Boston or Buffalo — not because of poor planning, but because mid-Atlantic winter infrastructure is sized for rare snow, ice events are more common than pure-snow events, and the rain/snow line shifts constantly through the region during storms.
Why Annapolis closes at lower thresholds
The mid-Atlantic sits at the precipitation-type battleground — storms that are pure snow at 40°N latitude often arrive at Annapolis as freezing rain or sleet as they cross warmer air masses. A forecast of "3 inches of snow" can mean clean plowable powder or a quarter-inch of ice under slush, and the difference is visible only once the storm arrives. District administrators have to make the closure call overnight based on limited information.
Annapolis's winter equipment is also proportionally smaller than northern cities. The plow fleet, salt stockpile, and bus-fleet cold-weather preparation are sized for the climatological average — which means a storm that exceeds typical accumulation overwhelms the system fast. Once major arterials are impassable, suburban and rural bus routes follow within hours.
Typical winter in Annapolis
Annapolis averages 19 inches of snow per year — a modest total by northern standards, but enough to produce 3–5 closure days most winters. Ice events and freezing-rain hybrids trigger more closures than pure snow.
- Seasonal snowfall: 19 inches
- Primary closure trigger: 2–4 inches + any ice risk in the morning commute window
- Freezing rain is more common than pure snow in mid-Atlantic storms
- Federal operating status (OPM) and surrounding district calls influence Annapolis decisions
