HERE IS AN UPDATE ON UPCOMING CHANGES TO NWS MODELS:
ETA/NAM
The last planned upgrade of the Eta model in the North American Meso-scale (NAM) system has been scheduled for 03 May 2005. At that time, the Eta codes will be frozen until they are replaced with the Weather Research & Forecast (WRF) model in the spring of 2006.
AVN/MRF/GFS
The resolution increase of the GFS from T254 to T382 has been scheduled for Tuesday, 31 May. The highest resolution portion of the forecast is being extended from 84 to 180 hours. From 180 to 384 hours the model resolution will increase to T190. The vertical resolution will remain at 64 levels to 180 hours and will increase from 42 to 64 levels beyond 180 hours.
RUC
In late June or Early July, the resolution of the Rapid Update Cycle (RUC) will be increased from 20 to 13 km. There will be no change in format or content of forecast model output. At some point in the future, 13 km output will become available.
