SGP/RUC/X1 - Wrong analysis code

Description:
NCEP Central Operations moved the suite of operational models to a new supercomputer on 
2005-01-25. Unfortunately, the code they used to build the executables for this new machine 
did not contain the changes made to the RUC analysis code on 2004-09-29. (See the posts 
on the RUC forum: http://ruc.fsl.noaa.gov/forum/f2/Welcome.cgi/read/1288
made around  2004-09-28 for more information.)  The result was some odd temperature and 
dew point analyses (and resultant forecasts) during this period and some general dryness.  
The error was found 2005-02-02, and the newest version of the code was introduced back 
into the model in the afternoon.  Unfortunately, due to cycling, some of the errors 
remained, so a new first guess (from a version of the model containing the updated code) was 
brought in for the 19Z cycle on February 3rd.
