A weak ridge extending from Norton Sound to the
Cook Inlet area will move eastward to extend from
the Northway area by 3 am Friday then continue

An upper low 400 nm southwest of Cape Navarin will
weaken into a a weak trough by 3 pm Friday. A
short wave trough currently extends from the low

southeastward to the eastern Aleutians. This feature
will weaken and move eastward through 3 pm Friday,
with a weak upper low remaining over the northern
Gulf of Alaska south of Middleton Island. This
low will weaken into a trough just offshore from the
panhandle by 6 am Saturday.

The next transitory ridge will move onshore along the
southwest mainland coast by 3 am Saturday, then
move eastward to extend the central and eastern
Alaska Range by 3 pm Saturday, then push eastward
into Canada Saturday night. A period of strong
winds aloft across the Alaska Range can be expected
