How accurate should a weatherman's forecast be? 1-5 days, for example.?

Depends on where you live.\n\nWhen I lived in Florida, forecasts were accurate 90% of the time(exception: hurricanes). They can usually predict an average FL forecast 5 days in advance.\n\nHere in Denver, it is hard to predict what a front will do when the mountains to the west make it hard to predict- a good forecast is accurate for a day or 2 at best.

All the time.  I would say about 5-7 days is average.

Come on Carl!  You live in Michigan and you have to ask this question?  They don't dare forecast the weather more than an hour ahead cuz they know it could change at any minute!!!  Summer weather?  You want to know what the summer weather's going to be like?  Hot.  Cool.  Windy.   Dry.  Rainy.  Cloudy.  Sunny.  Humid.  Warm.  Foggy.  Clear.  See anything you like?  That'll be the weather eventually this summer.  Oh yea, I live in Michigan too!  :)

If you mean how can we forecast the weather, it's largely a matter of  measuring teh movement or change of wind currents, humidity, and a number of other factors.  Now, most of that is fed into a computer, and it gives aprediciton of what the weather will be over a short period of time.  Or, you could use an ancient Indian weather rock:  If it's hot, the sun is out; if it's wet, it's raining; if it's swinging, the wind is blowing...

I broke my arm when I was 12.  It doesn't bother me now.  However...I had surgery on my left knee when I was in my early 20s and now I have my very own built-in barometer.  I know way before the weatherman when precipitation is on the way and I know when his 3-day forecast is wrong.

Your 5-day mean, while it has a smaller interval, is less accurate.  Your 10-day mean, while it has a larger interval, is more accurate.  To better understand this without math, its best to understand that as your number of samples goes up, your data will "normalize", or approach a consistent distribution.  While it is impossible to say within what finite range, with 100% accuracy, your mean will fall, your interval will become more and more accurate as your number of samples increases.  So, as per predicting the results after tomorrow's data is entered, your 10-day mean is more accurate.  Understand also, though, that neither mean is a tool for predicting the results of tomorrow ALONE, rather they are tools of predicting the interval after tomorrow's data is ADDED to the data ALREADY COLLECTED.\n\nSteve

You probably would have been better off just checking a weather site to get this info.  Sorry...

Well, weather forcasters are much better at predicting the weather since they were 20 years ago, but even with high technology, weather is hard to predict because the atmosphere is changing every minute, tha'ts why forcasters update their forcast that often through the day.

(Dunno, but weather's s'posed to be good there in the fall...)\n\nTry the Old Farmer's Almanac - they have long-range forecasts.\nhttp://www.almanac.com/weathercenter/

www.weather.com\n\nYou can enter your zip and sign up for daily weather report e-mails. You can also download a program onto your desktop that give you real-time weather updates.\n\nBTW, I think the reason the zip doesn't work is because you have 1 too many digits. Standard zip codes are 5 digits.

I think the weather channel has information like that. check their site. Or put it on search online and you may come up with some hits or leads.
