The Weather Research and Forecast (WRF) is a mesoscale numerical weather prediction
(NWP) model run at the NWS Raleigh four times a day. Our model configuration uses two
domains, a 12km WRF-NMM will be run at 00z and 12z out to 36 hours, using 12km NAM initial/boundary
conditions. The 4km WRF-NMM will run at 00z and 12z out to 24 hours, using 12km WRF-NMM (local)
and NAM boundary conditions.
The 12km WRF-NMM model run is available at approximately 30 minutes past the hours of
12 AM at 12 PM (EST) each day with the 4km WRF-NMM model run available
at approximately 30 minutes past the hours of 1 AM and 1 PM (EST) each day.
We expect to use the model in both an operational and research capacity to help refine
phenomena related to smaller scale weather events that are common to our
area. In addition, the model will allow us to produce and examine model fields that are
not readily available to support operational needs as well as research and collaborative projects. Finally,
we expect that the overall knowledge and understanding of how numerical weather prediction
models (NWP) operate will increase, resulting in improved NWP utilization at our office.
This is an experimental project. It may not always be available or may be
changed without notice to support local research and model experimentation.
Special thanks to Bob Rozumalski who provided the
WRF-EMS modeling package
and the
NWS Baltimore/Washington for their assistance in the development of the RAH-WRF and this webpage.
