Does the fact the map was for January affect your analysis? (You probably noticed; if not, this is FYI.)

I can't get a February map until early March. I'll be curious to see how much different it is than January. There will be some differences, of course.

Not much, Jan 2007 was 8 days above avg; 15 below and 7 avg.

Two and one half days were 20F above but were canceled out by the greater number of days below.

What is unusual is that when there were days above they were much above, reflecting a large movement of warm gulf air ahead of a steep gradient from the north and very cold air.

I don’t understand how the graph you presented is so smooth in its analysis.

While I have serious issues with the surface station locations and placement and the collapsing numbers of the total sites, I still think we must use the raw data before we make all the corrections to better fit the modeling process.
