The primary feature on the weather map is an upper low centered just south of Seward. This is the same upper level low that moved out of the northern Yukon at the beginning of the week and has brought moderate to heavy rainfall to the majority of the mainland.
This low will sag south slightly, then stall and continue to weaken. Ahead of it, rain is coming onshore into PWS and the SE Panhandle. On the backside of the low, rain is ending and dry air at the mid and upper levels is trying to punch into the Inlet region. Clouds will continue to gradually break up into the afternoon in Anchorage and the entire Cook Inlet area. Highs will rebound into the upper 50s and low 60s.
With rain and rain showers forecast today, highs will be cool in PWS and SE. Expect upper 40s to mid 50s.
Widespread sunshine is forecast elsewhere thanks to a broad upper ridge of high pressure smack-dab over the Bering Sea. Weak, dry northerly flow aloft is suppressing cloud development for a big chunk of the state. The Alaska Peninsula, Bristol Bay region, western Interior, all of the west coast, and the Arctic coast will have mostly sunny to sunny skies. Clouds will continue to decrease over the central and eastern Interior.
With the sun out, evening temps will climb into the 60s and 70s inland with 40s and 50s along the coast.
A strong disturbance well south of the the Aleutians will bring an increase of clouds and isolated showers to the Chain. Winds will become very strong throughout the Aleutians between this low and the high pressure region in the Bering. Winds may exceed 60 mph through channeled terrain in Adak.
