HRRR Severe Weather Parameters • Point Forecast

Click a location on the map or enter coordinates to request actual HRRR instability and wind fields. This is a point forecast, not a national CAPE or tornado-potential overlay.

LATITUDE LONGITUDE

Choose a location to request HRRR parameters.

Forecast fields available from the public point provider may include CAPE, convective inhibition (CIN), lifted index, dew point, wind and precipitation. Helicity, shear, STP, SCP and updraft helicity are not shown unless a verified provider supplies those exact fields. Data source: NOAA HRRR as served by Atmostorm; availability and browser access are not guaranteed.

NOAA HRRR • 3 km

High-resolution short-range model covering the contiguous U.S. Forecast runs are issued hourly.

Real model imagery

Actual HRRR forecast imagery, plus separate radar, MRMS rainfall and satellite imagery from Iowa State Mesonet.

Updated forecast

HRRR forecasts use selectable lead times. Radar, rainfall and satellite layers show the latest available observations or estimates.

Important: The two HRRR map layers and the optional HRRR point diagnostics are forecasts. Radar, MRMS rainfall and GOES satellite layers are observations or estimates, not HRRR model output. HRRR model forecast data is not a live radar observation or an official warning. If the public imagery service is temporarily unavailable, the basemap remains visible and the page reports the failure. Source: NOAA HRRR via Iowa State University Mesonet. Service availability and map performance depend on the external provider.
