[GEMPAK #DIT-578290]: Question: weather generation software

Wayne,

GEMPAK is an analysis and display package for data. It is not
a model or something that would be used to create output
such as what you are looking for.

Retrospective data since 1979 can be found at NCDC under what is called
the North American Regional Reanalysis (eg NARR). NCEP
also provides a coupled Climate Forecast System as is described here:
http://cfs.ncep.noaa.gov/

The NARR may provide you with a long enough history, but you would likely
want to subset the area down to a small region through the NOMADS server
nomads.ncdc.noaa.gov, otherwise you would be looking at
a tremendous volume or data.
