Weather Radar 10 Day Forecast (2024)

FAQs

How accurate is a forecast 10 days out? ›

The Short Answer:

A seven-day forecast can accurately predict the weather about 80 percent of the time and a five-day forecast can accurately predict the weather approximately 90 percent of the time. However, a 10-day—or longer—forecast is only right about half the time.

RadarScope is the best weather radar app for people who really need (as opposed to want) accurate real-time weather alerts. An iOS/Android subscription gets you advanced radar interrogation, true radial NEXRAD data, Apple Watch/Android Weather integration, and 24/7 live support.

According to ForecastWatch, the premier organization for evaluating the accuracy of weather forecasts, The Weather Company is more likely to be the most accurate across all geographic regions studied (U.S., Canada, Central America, South America, Europe, Africa, Middle East and Asia-Pacific) and time periods covered.

This comprehensive test analyzed over 25 million weather forecasts in more than 1,000 locations globally, and AccuWeather was the clear winner in high- and low-temperature forecasts, proving to have the lowest average absolute error and the greatest percentage of forecast accuracy within 3 degrees F.

Peer-reviewed research has concluded the practical limit to forecasting specifics is on the order of eight to 10 days. So how did AccuWeather's forecasts weeks and months into the future do? They were about half right.

Let's look at an example of what the probability does mean. If a forecast for a given county says that there is a 40% chance of rain this afternoon, then there is a 40% chance of rain at any point in the county from noon to 6 p.m. local time.

The WSR-88D is one of the most powerful and advanced Weather Surveillance Doppler Radar in the world. Since first being built and tested in 1988, it has been installed and used operationally at over 160 locations across the United States, including Alaska and Hawaii.

In a composite measure of accuracy, the Weather Channel and Weather Underground came top, AccuWeather fifth, MeteoGroup (the BBC's new provider) sixth and the BBC ninth (based on Met Office forecasts).

The Weather Channel: With its vast network of meteorologists and advanced forecasting technology, The Weather Channel app delivers highly accurate forecasts tailored to your exact location. It also offers interactive radar maps and video forecasts for comprehensive weather coverage.

The accuracy of weather predictions tends to decrease as the forecast period extends. The success rate for one-day forecasts is about 96-98%. It drops to about 90% for three-day forecasts. The more days in advance the forecast, the more likely it is that the weather will change.

NOAA Weather Radar Live

Many weather apps draw data from the National Oceanic and Atmospheric Administration. So, just cut to the chase with the NOAA Weather Radar Live app.

With more than 50 million downloads, MyRadar has proven to be the most powerful and accurate radar + weather prediction app on the market!

10-14 day forecasts are typically reasonably accurate depending on the model and local complications. A climate prediction might be okay past a week. Weather prediction, on the other hand, is not accurate at all past 7 days and is unlikely to improve.

- A seven-day forecast can accurately predict the weather about 80 percent of the time. - A five-day forecast can accurately predict the weather approximately 90 percent of the time. - However, a 10-day—or longer—forecast is only right about half the time.

"Research has repeatedly reached the same conclusions: We can predict the weather up to 14 days in advance at best," said Dr. Michael Riemer, a meteorologist at the JGU Institute of Atmospheric Physics.

Up to 3 days out is generally pretty accurate. 3-5 day forecasts have varying accuracy depending on how active things are, and >5 days climatology is best.
