.DISCUSSION...
High pressure persists over the Copper River Basin which is
allowing for mostly sunny conditions and high temperatures in the
low 70s. Min RH values will be in the upper 30s and lower 40s due
to drier weather. Breezy southeast winds in the Copper River
Valley continue through Tuesday. A front moves in on Wednesday,
increasing cloud cover, rain chances, and cooling temperatures
slightly.
