We have a big storm system heading into the Gulf of Alaska that will affect areas of southwest, south central, and southeast Alaska through Thursday. South central and southeast will see the brunt of this storm. This system is going to bring much warmer air back into south central, windy conditions in places, and widespread rain and snow from south central into the southeast. In south central most of the snow and rain will be found around the Prince William Sound and eastern and southern Kenai peninsula on Wednesday. The onshore flow will be out of the southeast so things will be fairly dry much of the day Wednesday from the western Kenai Peninsula, Anchorage Bowl, and Matanuska Valley. As the center of low pressure moves closer the the region on Thursday we will see the winds diminish and the flow will change allowing for the precipitation to become more widespread by the afternoon. Snow will likely linger into Friday before things quiet down again by the weekend. In the southeast this system will primarily be a rain event for you. Good news for Interior Alaska and the western half of the state is that this more active weather pattern is going to allow much warmer air to move north and westward. Expect a nice warm up by Sunday in these locations.
