Seven-day outlook

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 Plainville?
The nearest Doppler radar is KBOX (Boston, MA), 11 miles to the ESE. 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 Plainville its center is about 570 ft above ground. That is about as close as radar coverage gets in the United States: the lowest scan is still near the ground when it reaches Plainville, so low-level rotation and the leading edge of a gust front show up on it. Plainville is closer to its radar than 94% of US cities.
The closest instrument actually measuring the air is K1B9 · Mansfield Muni on the ASOS/AWOS network, 7.2 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.
