Worcester County, Massachusetts
Seven-day outlook
34–64°F across the weekThe week runs between 34° and 64°, with today the warmest day of it. There is no real trend across it: one day looks much like the next. Every day in the outlook stays dry.
Forecasts come from the National Weather Service's own computer models, and current conditions from the nearest reporting weather station. Both are served through the weather API. A forecast is guidance, not a warning, and anything the Weather Service has actually issued is on the live map.
The written summaries on this page are generated from the forecast data above, not by a meteorologist. Each sentence is a reading of the same numbers you can see, and no forecaster has reviewed them.

How well can the network see Princeton?
The nearest Doppler radar is KBOX (Boston, MA), 51 miles to the SE. A WSR-88D's lowest routine scan sits half a degree above horizontal, and the earth curves away beneath it, so by the time that beam reaches Princeton its center is about 3,700 ft above ground. That is comfortably inside the useful range. The lowest scan passes low enough over Princeton to show rotation in the part of a storm where tornadoes actually form.
The closest instrument actually measuring the air is KFIT · Fitchburg Muni on the ASOS/AWOS network, 9.3 miles away. Near enough to be representative on most days, though a summer thunderstorm can soak one and miss the other entirely.
Beam height is the standard 4/3-earth approximation for the 0.5° scan and assumes normal refraction; it is where the center of the beam is, not its edges, and unusual temperature profiles bend it. Radar siting from the NWS WSR-88D network, station positions from the Massachusetts observing network as of this build.
