Commercial Weather Outlets such as,
Accu Weather
The Weather Channel
Weather Underground
Intelicast
Weather For You
Dog Pile
and USA Today, All depend on the (NOAA) National Oceanic Atmospheric Administration’s, National Weather Service (NWS) for there weather reports.
The Information that the Commercial Outlets recive from the NWS is then interpited and modified for rebroadcast to meet there clients needs.
NOAA’s National Weather Service is the primary source of weather data, forecasts, and warnings for the United States. Television weathercasters and private meteorology
companies prepare their forecasts using NOAA information. The National Weather Service is also the sole United States official voice for issuing warnings during life-threatening
weather situations.
the website that pilots rely on
none it seems weather men are just guessers and not scientists
this is a long explanation, but i think its the only plausible explanation as to why weather forecasts are never 100%accurate. Weather is classed as a chaotic math. it is impossible to measure every factor at its infinite level of precision. For example, if you took a number with 7 decimal places and rounded this number to 2 decimal places and multiplied this number by x, and took this answer and rounded it up to 2 decimal places and multiplied it by x, and did this one hundred times, the answer would be very different to the answer you would have reached if you had kept the 7 decimal places. two different weather stations may have different levels of precision, no matter how close their precisions, the resulting answers will be very different. weather as a chaos math can be summarised by the saying, "the flap of a butterfly’s wings in Brazil sets off a tornado in Texas?" so basically unless every single movement on the planet that could contribute to the atmosphere and the weather is accounted for, such as a butterflies wings, a precise forecast will never be made, your best bet is to look at all the forecasts and make your own prediction lol.
It’s a prediction for each weather station, each weather prediction might be different. My best guess to see the most familier maps which might be the answer.
None are right all the time weather is not true science yet but its getting there as far as bring accurate.Too many landscapes and varitables can or will change any forcast at any time.Great question!
You will never find a website that is always correct. There are just too many variables in forecasting weather and while we are making headway in forecasting, it is just not feasible to monitor and predict every nuance of the current and future atmospheric conditions.
All that said, the best thing to do is learn to read the forecast discussions from the NWS. These are very detailed forecasts and they often explain why something may or may not happen. Learning to view the forecast models can also help you better understand the forecasts for your area. Watching how the models change overtime can often give you a general idea of how the forecast will change.
All of that gets a little complex, but once you learn to use some of the available forecasting tools as opposed to the "type the zip code in and get a little cloud icon" you can start to better understand the forecasts.
