Computer Model MOS Guidance

***NCEP has completed the transition from ETA to WRF/NMM in the NAM system. However, MOS output from the WRF/NMM was found to be considerably less accurate than the current ETA MOS. Therefore, NCEP runs an interm ETA model at 00Z and 12Z for input into the ETA MOS. This is only temporary.***
