.DISCUSSION...

Dry conditions with intermittent cloud cover are expected to
persist through Monday. Multiple upper level disturbances moving
northwest from the Gulf will support a slight chance of a snow
shower or two through this evening, but the majority of this
activity will likely stay to the south of the Chugach Mountains.
Expect winds to stay light and variable, generally 5 mph or less
near ground level through Monday. There is some potential for
northerly winds around 10 to 15 mph to mix down into the Chitina
River valley during the afternoon hours, but expect gustier winds
to mostly stay over the Wrangell Mountains through this evening.
