Does anyone know of a site that doesn't consistently get the forecast wrong?

Well, in their defense, 1PM is afternoon - not morning. ;)

They also put a percentage on the change of rain so you can use that to help make your decision.

I was just talking with some friends about this last week. I live by those reports. 15 years ago the only thing the reports were accurate for was what the weather was guaranteed not to be. Now-a-days I find the 24 hour report almost spot on (90% probability) 3 days out pretty close (75%), one week out (50%); Temperature, wind and precipitation all generally add up.

In Ottawa you gotta factor in some variance for the valley... Off of lake Ontario you get Lake effect.

I use them for fishing, my buddy for cycling.

As far as probability of precipitation goes with the forecast, what most folks don't realize is that when it says a 40% chance of precip it means that 40% of the coverage area has a chance of rain or snow, not that there is a 40% chance of showers in any spot in the area. That's how it was described to me, if that makes sense.

Cheers

It's very confusing, "40% of the coverage area has a chance of rain or snow", how much of a chance? Will 40% of the area definitely get precip? What are the boundaries of the coverage area? Which 40% will get wet? I find Accuweather to be OK short term, but the next day forecasts usually change overnight, I have to give 48 hours notice for time off and it sucks to sit at home when the weather prohibits fishing. :(

They go by past data that has been collected. When they say 40% chance of rain it means whatever the conditions are or were in the past 40% of the time it rains

I can fish in anything so I really only need wind forecasts. I use windfinder and windguru, fairly accurate. Unless I'm seeing a 40 mm rain day I go anyways.
