@JeffBeck-NOAA Do you remember why we had decided to set this to 48 hours originally?

The GST was chosen as 20190615 with a 00Z initialization and 48-hr forecast length to cover two full diurnal cycles, including two days with significant severe storm reports in various parts of the country. There is an increased demand by NWS and NSSL for CAM systems to be run into day two (24-48 hrs) time frames for forecast guidance relative to hazardous weather. The preliminary configuration of the RRFS (the main operational instantiation of the SRW App) will be run out to 60 hrs, four times a day.

Since the GST in the config.community.sh script uses a 25-km domain, I would advocate to keep the 00Z initialization with a 48-hr forecast. That's very computationally inexpensive. It also provides the general user with two days of forecasts to plot/compare.

@EdwardSnyder-NOAA Have you been getting failures later (after 6 hours) into the forecast? Just trying to understand the comment in the PR:

The forecast length was reduced to increase the likelihood of a successful model run.
