Changes to NAM MOS Station Elements

Effective Date: August 16, 2016

MDL will implement updated guidance for the NAM MOS 3-h temperature, Max-Min temperature, and winds with the 1200UTC model cycle on the date of implementation as given in the TIN. We are implementing these updates to include output from the latest version of the NAM (v3.1), which will better tune this guidance to the error characteristics of the operational model. Due to changes in the reporting habits of individual sites and the resulting impact on observed data available for development, we will be adding or dropping warm/cool season guidance for NAM MOS temperatures and/or winds for the sites listed in the tables below.
