GFS changeover and new version

Update: Sam found the problem and fixed it. The problem was that NCEP is now putting two different accumulated precipitation fields in the data (the old one accumulated over the last 3 or 6 hours, and the new one since initialization, and BOTH are now in there), and they were labeled APCP(1) and APCP(2), and we’d been searching for the tag APCP. This garbled up a couple of the variables. In any case, it’s fixed, and we’re poised to switch over for the 12Z data tomorrow.

I don’t know the details of Chris McMahon’s script in this regard. It may or may not be affected by this redundancy, but if it is, I think my precautionary move will at least prevent errors (though it’s conceivable something else might be affected). In any case, he will be home in a few days to address anything that might come up. Meanwhile, the Bohler data should be sound.
