is there a 30 day forecast??

Answer 1

If you're looking for a day-to-day forecast for 30 days in the future, that doesn't exist. However, if what you want is a general forecast (warmer/colder, drier/wetter than normal), then you can find what you want at the Climate Prediction Center website.

Answer 2

I don't know if it's a forecast in the same sense as, say the 7-day forecast. But there is a long range forecast that talks in generalities about temps and precipitation being higher or lower than averages.

Try NOAA or you local NWS (insert city name here)

Answer 3

I'm sure you could find one, but why? The 5-7 day forecasts are rarely accurate. The weather forcaster just inputs information in a computer and the programs interprets what it thinks the result will be. Earlier this week, our local weather predicted 6-8 inches of snow. We have less than an inch and the storm is moving out.
