Stan, I was only interested in NCEP vs FSL RUC since I was seeing an apparent systematic difference of the 2m Temp at a location I was interested in which averaged out to 1.3C and was trying to wrap my brain around what might be causing the difference - based on what I had read I had thought that the land use parameters were the same in both so it must be assimilation/initialization differences but wanted to make sure I hadn't made an incorrect assumption. That comparison was only over 10 days but the std.dev. was much smaller than the avg. difference so was consistent. I will see what happens after the change (and over a longer period!). The forum email with your message caught me reading about the new changes. I know the areas I've looked at, notably around Dallas, tend to have underpredicted BL moisture and the changes sound like they will help improve that. Thanks. Jack
