Which forecasts have become worse in Boston? 24 hour, 5 day, all of the above? This is surprising to me, because even when traveling across the USA, I've found the predictions to be very useful.
All forecasts. I race sailboat around Boston and they've been absolutely horrible. Not just for extreme weather events but even regular weather wind direction is off by nearly 180 degrees in direction regularly, wind strength is regularly wrong too. The predictions overemphasize rain events in the 10 day forecast during the Summer that nearly always completely go away and they fail to predict rain and lightning events. That's overing multiple weather models at various resolutions.
