ANCHORAGE, Alaska (KTUU) - While under cloudy skies Sunday Anchorage will see a high near 10 degrees.
Very cold, Arctic air remains over the Copper River Basin. This combined with the changing of temperatures and air pressure over a short area continues to promote strong winds out of bays and passes.
These gap winds will increase when a third component comes into play as another low pressure system develops Sunday near Kodiak Island. This additional component will further strengthen winds Sunday into Monday.
Wind and cold will keep the advisories going through Thompson Pass through Sunday at Noon because we can still see 50 degree below zero wind chills during this time frame. On Sunday, storms could combine in the Kodiak Island area with the chance of bringing widespread snow showers to Kodiak, the western Gulf, then northward to the Kenai Peninsula, Anchorage and the Mat-Su. Though these storms could weaken as they move up Cook Inlet and into Southcentral.
There is the chance for up to 2" of snow with these storms but totals will vary. Winds out of the southeast could promote mountain blocking for some of these storms but as winds switch around then blocking could let snow fall across the area. Cold temperatures should keep Southcentral with snow fall while warm air from the east could bring a mix of rain and snow to Kodiak on Sunday.
For the extended period, after potential snow activity over the weekend, Monday through Friday looks to be dry and cold after temperatures stay and drop well below average again. A few snow showers will be possible across the southwest as several storms push inland. The Bering Sea will see the most active weather pattern as North Pacific storms move north. As the storms move slowly east we could see strong gusty winds and rain in the Eastern Aleutians and the Pribilof Islands. So we stay quiet and cold over the southern mainland but active weather wise over the Bering Sea and Gulf of Alaska.
Clear skies Saturday evening before turning partly cloudy later in the night as we drop down to 9 degrees below zero.
Cloudy skies in Anchorage on Sunday along with a 40% chance of snow while we warm up to 10 degrees for a high. Winds will be around 10 mph but closer to 20 mph along Turnagain Arm as well as in higher elevations. A chance of snow Sunday night as we drop down to 4 degrees below zero.
Partly cloudy skies on Monday in Anchorage as we warm up to a high of 14 degrees. Back down to 4 below on Monday night while under mostly cloudy skies.
Looking ahead, Tuesday we will be partly cloudy with a high of 3 degrees.
