This weather app will give you the most accurate forecasts

The Big Crunch

There are plenty of weather apps out there, but not all will keep you warm and dry.

Major weather services can range in their ability to predict rain and temperatures in a certain place by more than 25 percentage points, so picking the right app could make all the difference.

CNBC looked at how eight services predicted temperatures and rain at nearly 800 weather observations stations across the country, based on data from ForecastAdvisor (click there to enter in your own zip code). At the very top overall were Weather Underground and the Weather Channel, two brands owned by the same company, IBM.

When it comes to predicting whether it will rain one to three days ahead of time in 2015, Weather Underground and The Weather Channel have the highest average accuracy across the country at almost 84 percent. (The two apps sometimes give different results based on how a user's location is interpreted, but the underlying source is identical, the company said.)

The two apps came out as the most accurate options for predicting rain in a little over 60 percent of weather stations, which means that one of the other apps we looked at is still best in the other 40 percent. So the best app depends mostly on where you are: If you're in Miami, MeteoGroup is best overall. If you're in Los Angeles and worried about rain, stick with Dark Sky.

The Weather Channel and Weather Underground are again at the top of the stack nationwide for forecasting high temperatures, but AccuWeather far surpasses all rivals in its ability to predict low temperatures to within three degrees. That's in line with another analysis that found that AccuWeather is the most accurate temperature forecaster globally.

The business of predicting the weather can be far more challenging in some parts of the country than others. Areas near the coasts or other bodies of water are often easier to forecast than inland areas.

"There is wide variation in the ability of forecast models to make accurate predictions in different areas," said Eric Floehr, the founder of ForecastAdvisor. "The Plains states are notoriously difficult to predict because you're constantly having fronts battle it out."

Places like Florida, California and Alaska are easier to forecast with high accuracy. In California, apps predicted rain (or more likely, no rain) in some areas with more than 97 percent accuracy in 2015. Likewise, temperature forecasts are strongest in Florida. Overall, the hardest states to predict the weather in are North Dakota and Montana, where apps are only right about 64 percent of the time.

On average, the accuracy differences between various services are higher for temperature than precipitation. Almost all apps can predict rain with a high degree of confidence in California, but the gap is much higher between apps along the Gulf Coast, in the South and in Plains states.

To be sure, the straightforward metrics at ForecastAdvisor are just one of many ways to measure a weather app.

Floehr, who also runs an advanced service for measuring forecast accuracy called ForecastWatch, said that the basic statistics he publishes on ForecastAdvisor tend to generally be in line with more complex assessments. Still, it's hard to say conclusively that any one app is better than others.

"The technical work of collecting data from multiple providers over a comprehensive set of locations is a big task. So we use ForecastAdvisor for that," Samu Karanko, chief analyst at Finnish forecaster Foreca, said in an email. "Forecast verification is a science of its own and you need to study it for years to learn about all the pitfalls."

Data sourcing can make a difference too: MeteoGroup noted that the data in the ForecastAdvisor analysis comes from its website, while its WeatherPro app uses a new (and more accurate) API.

"Sometimes a less accurate forecast is perceived as being a better forecast"-Eric Floehr, founder, ForecastAdvisor and ForecastWatch

Additionally, what is perceived as accurate can change depending on how you use a service. That's why some weather services have been known to adjust their predictions to better serve their customers.

One famous example is the "wet bias" — when a forecaster reports a higher probability of rain than his or her models suggest to help keep people from getting wet if it does rain. The logic is that if consumers see that rain is unlikely and get wet, they'll be a lot angrier than if they see that rain is more likely and it doesn't rain.

"Sometimes a less accurate forecast is perceived as being a better forecast," Floehr said. "You could be more accurate, but you would have been more people unpleasantly surprised when they didn't have an umbrella when it rained. Different industries and users have different needs for forecasts and forecast accuracy."

Another example is scattered rain showers — if your app says scattered showers and it rains on four friend half a mile away but not you, was it wrong? The traditional way to deal with that uncertainty is by using probabilities, said Karanko of Foreca. While ForecastAdvisor doesn't track that data, Floehr has looked at rain probability accuracy for ForecastWatch.

The goal is to get as close to the black lines as possible — which means that when a service predicted 20 percent chance of rain, it actually rained 20 percent of the time. In this analysis of 2015 data, Dark Sky and AccuWeather seem to be the best at using exact probabilities.

Of course, exact predictive accuracy isn't the only thing that weather apps and services have to offer. Many users pick their favorites based on other features entirely, like a pleasant user interface or alert services. MeteoGroup pointed to its radar images and prompt customer services as defining features, while Jon Porter, vice president of innovation and development at AccuWeather, said the company prides itself on not only being accurate, but also helping users know how weather with affect them.

"During severe weather events, when lives and productivity depend on having a dependable forecast, we are not only giving information on what weather will occur, but we're also talking directly to our users about the impact," Porter said. "Other providers might just say 'thunderstorms this afternoon,' but we would say 'partly sunny with thunderstorms that could produce flash flooding.'"

Those details could make a much bigger difference to a user's experience than a few degrees of accuracy.

Weather services overall have been improving in recent years, and the accuracy of their systems can jump suddenly as companies implement new technology and models, said Floehr.

Does Does Floehr have a preference himself?

"In general, it's hard to say that one is more accurate than another in all domains," he said. "But I would say that companies like the Weather Channel and AccuWeather are definitely interested in accuracy and invest in making sure that their processes and models and meteorologists are at the forefront of technology."

UPDATED: 20 May 2019

I received an interesting email the other day from Staples telling me about their recycling program.  I always assumed I could walk into any big box store with my old electronics and pay a fee to recycle it.  This email told me that I could bring it there for free.  That made me start to wonder what other options are out there for our customers, not only to recycle but also, to possibly get a discount on their next purchase.  We frequently get calls from folks wondering about electronic recycling.  Here’s some helpful info.

If you’re thinking about fixing your older equipment, take a look at this article.

What to do first:

Once you’ve decided to get rid of your older devices, you must remove all of your sensitive data.  Delete all of your apps, all of your contacts, your emails, your texts, photos, etc.  Many of the Electronic Recycling Programs say that they will do this for you before they sell it to someone else, but why take the chance?  (Yes, we can help you with this if you’d like.)

Why do you want to Recycle your Electronic Devices:

Many of the components in our electronic devices are toxic, so it’s really important to make sure they get recycled properly. If you just toss your laptop battery in the trash, many of those toxins will leach right into our water supply!

Electronic Recycling Options:

You have a  whole bunch of options for getting rid of your old stuff:

Sell It

Rather than electronic recycling, you can try to sell your old phone, tablet, or computer. (Remove your personal data first!) You could start with eBay or Craig’s List.  You can also try buy-back programs at places like Best Buy, Amazon, AT&T, Sprint, Staples, and Apple.  You’ll get a little less money for your device, but it’s really easy to do, with much less hassle than finding a buyer, shipping it, etc.

Donate It:

Habitat for Humanity, Goodwill, Salvation Army, etc. But, first of all, remember to remove your personal data!

Give It Away:

Put the item on your local Facebook page, or post it in your local Freecycle group.  But, please make sure that you have removed all of your personal data first!

Recycle it Properly:

If you’re not able to sell your equipment or give it away, bring it to an authorized recycling center. Head over to this website and enter your zip code to find the nearest place to you.  This is sponsored by DirecTV, but I took a quick look at the recycling centers in my area. It seems like they take more than just TVs. Expect to pay anywhere from $5-$50 to recycle your equipment.

Before you sell, give away, or donate your equipment, remove your personal data!
