.DISCUSSION...
With the arctic airmass still over the area today and tomorrow,
surface temperatures will remain seasonable. Rain chances are
fairly low for the Upper Tanana Valley. Overnight Sunday might
have the best chance to see showers, but not much rainfall will
be associated with these showers. Southerly gap winds through the
Alaska Range are expected to start back up this afternoon and
will last overnight tonight. Some gusty winds could make it to
Tok, but the strongest winds will remain in the passes.
