LONG TERM FORECAST (Days 4 through 7: Friday through Monday)

On Friday, A weak Gulf low will generate showers to Southcentral Alaska and A high over the Kusko Delta will bring fair weather to Southwest as well as the Alaska Peninsula. Both systems will dissipate by the afternoon. A trough over the Bering will bring showers to the Aleutians Friday through Monday.

An upper level ridge over the eastern Gulf will remain nearly stationary through Sunday and then move eastward by Monday. This is important as it blocks an originating Pacific Low from going into the eastern Gulf. The combination of the anticyclonic flow aloft from the ridge and cyclonic flow from the low pressure system will enhance southerly flow ushering in warm and moist air into the northern and western Gulf coast. This is expected to bring precipitation to Southcentral Alaska, Alaska Peninsula, and Kodiak Island. There is strong model confidence that there will be periods of heavy rain for Prince William Sound and Kodiak Island Saturday into Sunday.
