Good links triple T.
I use this link as my one stop weather shopping spot: Pacific NW 7-Day Zones Forecasts
A nice feature is after you click the appropriate zone it gives you the option to click on a second, more detailed map for a "detailed point forecast" which appears on the right. Doing this will give you the forecast (how accurate it is I'm still determining) for the particular location and elevation.
Good example: Mt Stuart
Play around with clicking different points on the detailed map and watch how the location (given as a distance from some town) and elevation change.
