.DISCUSSION...A colder trend is in store for the region as a broad
low pressure system from Alaska moves toward the Pacific
Northwest. Expect an uptick in winds through the start of the work
week, with periodic chances of snow as snow levels drop to below
3500 feet, however no meaningful accumulations are expected for
the site. The forecast beyond Tuesday is shrouded in
uncertainty, however latest weather models suggest a return to
more seasonably average temperatures and drier conditions.
