Past Weather Forcast Database?

I'm trying to find weather stats for late September on Baker, Shuksan, Boston Basin, and around Mt. Triumph. The forecast models on www.nws.noaa.gov would be fine, but I don't know how to look at past forecasts. Can anyone help?

So do you want the archived actual weather data, or archived forecasts?

Either/or/both. I'm just trying to put ballpark numbers into a narrative report, so accuracy doesn't count, but does make it easier. Is there anyway to get the Wx data from the Mt. Baker and WA pass telemetry stations for those dates? Who do I email?
