VERY IMPORTANT AND NOTE, the forecast is for the grid box, and not necessarily for the mountain summit. See Image Below In the 7-day forecast GIS map, there is a 'green' box.

The forecast grid box mid-point elevation is 13,750 feet.

Here is a Google Earth 3 dimensional look at how the forecast grid box is tied to ground level, and shows the various terrain within the grid box.

Just remember, the "point" forecast is for a grid box that includes the mountain summit, and the "point" forecast is not necessarily specifically tied to the mountain summit elevation.
