Today, the High-Resolution Rapid Refresh model became operational at the National Weather Service. The model, commonly known as HRRR, is a great tool to help meteorologists forecast weather for local areas, due to its high resolution. Model runs are put out every hour in 15-minute intervals, and forecasts extend out 15 hours.
Often you'll see a tweet about the "HRRR Future Radar" Curious what it is? Details from @NOAA: http://t.co/IAie5Wwthn pic.twitter.com/okFJgngWei

Researchers at NOAA’s Earth System Research Laboratory have been working on the HRRR for the past five years, but until today, it was not officially operational. The HRRR is revolutionary in its forecasting abilities, as it will assist meteorologists in pinpointing specific areas under threat of tornadoes, hail, and other hazards that evolve with storm development. According to a recent news article put out by NOAA,
Hyper local forecasts are possible with the HRRR because of higher resolution. The HRRR’s spatial resolution is four times finer than what is currently used in hourly updated NOAA models offering a more precise prediction of a storm’s location, formation, and structure. Using the HRRR, forecasters have an aerial image in which each pixel represents a neighborhood instead of a city.
The High-Resolution Rapid Refresh model will greatly improve the timely manner of storm watches and warnings, and ultimately save lives. For more information on the HRRR, visit NOAA’s website.
