These forecast images show the
RAP
(Rapid Refresh) forecast for up to 6 hours from now. We process the data using the same routines used by the SFCOA system, resulting in a consistent set of images.
The background reflectivity forecasts are from the latest
HRRR
.
Currently, forecast images are only available for a selected subset of mesoanalysis data. The images are updated every 3 hours.
