Models continue to dance around the mostly agreeable but washed
out ensemble means with only modestly robust systems forecast
later next week into the weekend. Latest GFS/ECMWF were close
enough to the ensemble means to use a blend of that guidance
cluster as a starting point, which maintained decent continuity.
Axis of upper ridging should mostly stay strewn across the
interior from southeast to northwest, keeping any system over the
Aleutians or through the Gulf in a weakened state.

Dry period for most of the interior as precipitation will focus
along the southern coast especially into the Panhandle with the
lead system Wednesday (heaviest over the southern Panhandle). Rain
may then be heavy over the eastern Aleutians with the second
system (including south-facing upslope-favored regions on the
AkPen and Kodiak) Wed-Fri and whatever is left of it by Saturday.
By then, yet another system is forecast to lift
north/northeastward of the central Pacific toward the Aleutians.
