UPDATE 1/16/2020: The NWS Albuquerque 5km and 1km WRF-ARW modeling domains will no longer be supported after March 2, 2020. There are various other high resolution modeling resources available, including but no limited to; the Storm Prediction Center 3km WRF-ARW, WRF-NMM, and HREF-2, the Texas Tech University 3km WRF, the Earth Systems Laboratory 3km HRRR, and various high resolution NAM/WRF nests from the Environmental Modeling Center. We would like to send special thanks to Robert A. Rozumalski, PhD, for his invaluable support of our local modeling operations over the past 11 years.

Basic Description
5.0km WRF-ARW: Run every 12 hours out to 48 hours using NAM initial conditions and boundary conditions. The default domain is centered over New Mexico.

1.0km WRF-ARW: Run every 6 hours out to 24 hours using NAM initial conditions and boundary conditions. The default domain is centered over the Albuquerque and Santa Fe metro areas. The domain is moved to support decision support activities.
