A large low and rigorous upper trough have brought clouds and rain to all of Alaska. Situated near the west coast, this 997 mb low is weakening and moving to the northeast as the trough lifts over the state. Until it clear the area late tonight, showers remain likely, with some heavy showers possible.
Jet moisture surging north out of the Gulf of Alaska will bring steady rain to the PWS and the northern Panhandle. Periods of rain with a few embedded heavy showers will rotate around the low through SW, Southcentral, and Interior Alaska. Showers wrapping around the north side of the low into the west and northwest coast will continue until late evening.
Highs will be in the 50s nearly statewide. The eastern Interior will have 60s. The western Slope will stay in the 40s.
There is some clearing occurring over the Bering Sea as an upper ridge begins to build. The most predominant drying will be over the Aleutians. Mostly sunny skies and light winds are forecast for Adak and, by afternoon, Dutch Harbor.
This storm is very large and is dropping rain totaling over an inch in areas. Clouds will begin to clear west to east over the state tonight into tomorrow. Look for rain to taper off in Anchorage late tonight. Clouds will begin to break tomorrow morning as dry air pushes in. We'll have some sun out tomorrow afternoon or evening, mostly cloudy skies Saturday, and pleasant temps with periods of sun through the weekend.
