Central Massachusetts
Worcester is inland and considerably higher than Boston, which is exactly why it keeps snow when the coast changes to rain. The estimate below is loaded with live Worcester forecast data.

Local conditions
Worcester sits on the hilly uplands of central Massachusetts, well away from the moderating influence of the Atlantic and several hundred feet above sea level. Both factors work in the same direction during a coastal storm: the city stays colder for longer, so precipitation that has turned to sleet or rain in Boston is often still snow here. The same geography means events tend to start earlier and last longer, and cold between storms preserves snow and ice on secondary streets rather than melting them away.
What actually drives a decision
During marginal storms the difference between Worcester and the coast is not luck but altitude and distance from water. When the forecast shows a rain-snow boundary anywhere near eastern Massachusetts, expect Worcester to be on the snow side of it, and read the temperature factor accordingly.
Worcester's terrain includes numerous steep residential streets. Small amounts of snow or ice on those grades create traction problems for buses well before flat main roads become a concern, which is why an apparently modest event can still disrupt transportation.
Because central Massachusetts storms often run longer than coastal ones, crews may need multiple passes and treatment may be undone by continuing snowfall. Read the previous-evening and overnight snowfall windows together to see how many hours of accumulation preceded the morning run.
Worcester frequently stays below freezing between events, so packed snow and ice persist on side streets and sidewalks. A later modest snowfall lands on an already compromised surface, making it more consequential than the same event on bare pavement.
The forecast for the coordinates above is scored against six weighted factors: snow and ice, temperature, wind chill, morning timing, area and routes, and school level. Around Worcester the rows that most often carry the number are snow and ice, temperature. Every factor appears in the result with its own value, score bar and published weight, so a percentage is never presented without the reasoning behind it. The methodology page documents each threshold, and the accuracy and limitations page sets out what the model cannot observe.
This site does not publish closure thresholds for any school system, because those are operational judgements rather than published numbers. What it can do is point you at the organisations that actually decide. Around Worcester, MA those include:
Treat the estimate on this page as a reason to prepare and to keep checking, never as an announcement. A school system can close buildings, delay the start, cancel transportation only, dismiss early or move to a different learning format, and those outcomes are not interchangeable.

Worcester questions
This page estimates weather pressure only. Worcester Public Schools and the districts around it announce separately, and because central Massachusetts usually ends up on the snow side of a marginal storm, a Worcester closure alongside an open coastal district is an entirely normal result.
It is farther from the ocean and several hundred feet higher. Both factors keep surface temperatures below freezing longer during a coastal storm, so precipitation that changes to sleet or rain near the shore continues as snow inland.
Not directly. The area-type setting supplies broad transportation context, and the methodology explains that the model does not observe individual grades. In hilly terrain, treat a borderline result as more serious than the same number on flat ground.
The forecast is requested for Worcester's own coordinates, and the local context explains the inland elevation effect rather than coastal storm tracks. The two cities frequently see different precipitation types in the same system.
