UW-NMS Operational Forecast Information
The UW-NMS model
is normally run twice per day on an IBM RS/6000 model 580 using 00 UTC
or 12 UTC data. The operational
version of UW-NMS has few a differences from the research version.
A 48 hour forecast on 00 UTC data using all three model grids is usually
completed by around 5:30 AM CDT (10:30 UTC). A 48 hour forecast using only
the outer two grids is usually completed by around 3:00 PM CDT (20 UTC).
The model is initialized with the NMC Eta analysis, and the boundary condition
information is provided by the NMC Eta model forecasts every 6 hours. The
outermost grid has 160 km horizontal resolution, and covers most of North
America. The middle grid has 80 km resolution, and covers about the eastern
two-thirds of the continental United States. For the 00 UTC runs, the innermost
grid has 27 km resolution, and covers most of Wisconsin, Lake Michigan,
Lake Superior and portions of surrounding states. Forecasts are available
here in GIF format at 6 hourly intervals, in GRIB format, and in VIS-5D file format.
