IMPORTANT MESSAGE:

On 31 August 2018, the NSSL-WRF website will be upgraded and moved to cams.nssl.noaa.gov. The new page will also display 0000 UTC initializations of NSSL-FV3 and HRRRv3 and include a link for model verification. Until then, this page will remain and we encourage users to check out the new page and provide feedback at: https://hwt.nssl.noaa.gov/fv3

[CLOSE MESSAGE]

Thank you for your support of the NSSL-WRF. On 31 August 2018, this page (https://wrf.nssl.noaa.gov/newsite) and the older version of this page (https://wrf.nssl.noaa.gov) will be replaced by the web domain https://cams.nssl.noaa.gov.

The following provides some background behind these changes. As part of a project funded by NOAA's Office of Weather and Air Quality, NSSL is performing real-time, convection-allowing forecasts out to 60 hours from the Finite Volume Cubed Sphere Model (FV3), which has been selected as the Next Generation Global Prediction System for the NWS. The goal of this project is to assess the performance and accelerate the development of FV3 at convection-allowing scales. Additionally, NSSL is continuing to provide forecasts from an experimental configuration of the Weather Research and Forecasting Model (WRF), known as the NSSL-WRF, to provide support to the Storm Prediction Center and other users, and provide a framework to test and develop new forecasting tools and diagnostics.

In order to simplify the dissemination and visualization of both sets of forecasts, these forecasts will be displayed using a single web page. Because the existing web domain, https://wrf.nssl.noaa.gov, no longer makes sense since we'll be displaying FV3 in addition to WRF, a more general domain name that encompasses both forecast models is needed. The web domain https://cams.nssl.noaa.gov serves this purpose (“cams” stands for “convection-allowing models”). Note, the new webpage will display the CONUS domain along with the option to display nine sector zooms, similar to the HREFv2 viewer at https://www.spc.noaa.gov/exper/href/. The WFO-level zooms will no longer be available. If you have questions, comments, or suggestions regarding this change please contact Adam Clark (adam.clark@noaa.gov).
