This product is issued twice per day, once by approximately 0630 MST/0730 MDT
(1330 UTC) and again by approximately 1830 MST/1930 MDT (0130 UTC).  It is not
continuously monitored nor updated after its initial issuance.

The information contained herein is based on rawinsonde observation and/or
numerical weather prediction model data taken at the Boise Airport site in
Boise, Idaho at

                   Latitude:    43.56774
                   Longitude: -116.21089
                   Elevation: 2867 feet (874 meters)

and may not be representative of other areas in eastern Oregon or southwest
Idaho. Note that some elevations in numerical weather prediction models differ
from actual station elevations, which can lead to data which appear to be below
ground. Erroneous data such as these should not be used.

The content and format of this report as well as the issuance times are subject
to change without prior notice.
