The meteogram spreadsheets below were crafted for the GFS run. However, they can be easily modified to make meteograms from the NAM/ETA or any other model data. I'll post links to NAM/ETA versions in the future.
First thing you'll need is a copy of Microsoft Excel, 2007 or later. If necessary, I can create an Excel 2003 version, but you really should update to a modern version of Excel.
Here are the links to the files:
The tutorial takes you through the production step-by-step, with pictures and arrows. The process may look a bit complex, but once you make a few of them you'll find that the whole process takes about 60 seconds.
