Cleveland's weather forecast is accurate only 3 days out

The intrigue: Cleveland's accuracy is on par with most cities in Ohio, neighboring Midwest states and those in the Northeast like Pennsylvania nd New York.

• States in the Great Plains see accuracy no more than two days out, while parts of Arizona and Florida can see accurate forecasts at least seven days out.

Zoom in: If you think Cleveland's weather is unpredictable, other Northeast Ohio cities on the lake such as Lorain and Sandusky have accurate forecasts just two days out.

What they did: The Post analyzed a year's worth of National Weather Service forecasts and forecast errors spanning April 2023 through this March to find how often they were correct within 3 degrees of the actual temperature that day.

The big picture: How accurate the weather forecast is depends on where you live.

• Coastal regions are simpler to predict because of how the ocean regulates temperature and southwest desert areas are also easier due to arid conditions.
• The vast middle of the U.S., however, sees quick and significant temperature swings that result in the least accurate forecasts in the country.

Yes, but: Data shows temperature forecasts nationwide have steadily improved over the last 50 years.

• "It's one of those quiet revolutions," Weather Prediction Center director David Novak told the Post.
