Figure 2.14. 24-hr simulated precipitation ending Nov. 11,2003, 0800 UTC.
This figure was generated by CSU using NCAR Graphics. Compare this figure
with Figure 2.11 that was generated by using the GrAOS graphics package.

The other two CSU projects that required the faster system ended in early
January 2004, and the RAMS 0000 UTC real-time forecast runs were switched
back to the faster cluster effective the evening of January 10, 2004. So
beginning January 10, 2004, through the transition to the new cluster, and on
through the end of the OW 2003-2004 Program's cloud-seeding operations, the
real-time forecasts were run on a fast cluster that should have provided timely
support for the seeding operations. The new cycle forecast was completed
around 0200 MST.

An operational problem that arose with the slower real-time forecast runs
also applied, bulto a lesser extent, with the faster runs. When a new forecast
