WRF offers two dynamical solvers for its computation of the atmospheric governing equations, and the variants of the model are known as WRF-ARW (Advanced Research WRF) and WRF-NMM (nonhydrostatic mesoscale model). The Advanced Research WRF (ARW) is supported to the community by the NCAR Mesoscale and Microscale Meteorology Laboratory.<ref>{{Cite web|url=https://www.mmm.ucar.edu/wrf-user-support-contributor-information|title=WRF User Support & Contributor Information &#124; MMM: Mesoscale & Microscale Meteorology Laboratory|website=www.mmm.ucar.edu}}</ref> The WRF-NMM solver variant was based on the Eta model, and later nonhydrostatic mesoscale model, developed at NCEP. The WRF-NMM (NMM) is supported to the community by the Developmental Testbed Center (DTC).

The WRF serves as the basis for the [[Rapid Refresh (weather prediction)|RAP and HRRR models]]: high-resolution operational forecast models run regularly at NCEP.<ref>{{Cite web|url=https://rapidrefresh.noaa.gov/RR.faq.html|title=Rapid Refresh Frequently Asked Questions|website=rapidrefresh.noaa.gov}}</ref><ref>{{cite web|url=https://dtcenter.org/plots/hwt/model.php|archive-url=https://web.archive.org/web/20150218185729/https://dtcenter.org/plots/hwt/model.php|title=HWT 2009 Spring Experiment Objective Verification|archive-date=2015-02-18}}</ref>

A version of WRF-NMM tailored for hurricane forecasting, [[Hurricane Weather Research and Forecasting model|HWRF]] (hurricane weather research and forecasting), became operational in 2007.<ref>{{Cite web|url=http://www.noaanews.noaa.gov/stories2007/s2885.htm |publisher=NOAA News Online |title=New Advanced Hurricane Model Aids NOAA Forecasters |date=27 June 2007 |accessdate=27 June 2010 }}</ref>

In 2009, a polar optimized WRF was released through the [[Byrd Polar Research Center]] at the [[Ohio State University]].<ref>{{Cite web|url=http://polarmet.osu.edu/PolarMet/pwrf.html |publisher=The Ohio State University Polar Meteorology Group |title=The Polar WRF |date=17 September 2009 |accessdate=31 July 2014 }}</ref>
