The study's twelve-month evaluation names AccuWeather the most accurate source of overall temperature forecasts measured through mean absolute error and forecasts within three degrees.

The Weather Channel had the highest percentage of first-place finishes over the study period and averaged over all forecast lead days (1-9) in each region studied, according to ForecastWatch, Global and Regional Weather Forecast Accuracy Overview, 2017-2022, https://forecastwatch.com/AccuracyOverview2017-2022, ...

If you're a weather geek, this is the app for you. Nothing fancy. Current temperatures are updated hourly, but other apps are better at showing the absolute current temperature. Thus 4 stars.

Whenever a tropical cyclone (a tropical depression, tropical storm, or hurricane) or a subtropical storm has formed in the Atlantic or eastern North Pacific, the NOAA National Hurricane Center (NHC) issues tropical cyclone advisory products at least every 6 hours at 5 am, 11 am, 5 pm, and 11 pm EDT.

What weather model does NOAA use? ›

The Global Forecast System (GFS) is a National Centers for Environmental Prediction (NCEP) weather forecast model that generates data for dozens of atmospheric and land-soil variables, including temperatures, winds, precipitation, soil moisture, and atmospheric ozone concentration.

Forecasters have issued a La Niña Watch, indicating that the cool phase of the El Niño-Southern Oscillation ("ENSO") climate pattern is likely to develop in coming months, with a 79% chance it will be in place for the Northern Hemisphere winter.

NOAA's dedicated scientists use cutting-edge research and high-tech instrumentation to provide citizens, planners, emergency managers and other decision makers with reliable information they need, when they need it.

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.

NOAA is forecasting a range of 17 to 25 total named storms (winds of 39 mph or higher). Of those, 8 to 13 are forecast to become hurricanes (winds of 74 mph or higher), including 4 to 7 major hurricanes (category 3, 4 or 5; with winds of 111 mph or higher). Forecasters have a 70% confidence in these ranges.
