ANCHORAGE (KTUU) - While under mostly cloudy skies Friday Anchorage warms to near 60 degrees.
Conditions will deteriorate across Southcentral Alaska this morning as the storm system over the Bering Sea approaches. As has been advertised in the last few days, the dynamics with this system are strong and moisture content is high. Thus, expect widespread rain for all except the Copper River Basin as we head through the next 24 to 36 hours.
A gale-force front (39-54 mph winds) will track across the Southern Gulf of Alaska and Kodiak Island this morning (Friday), then begin to slow down this afternoon as 2 to 3 systems meet up in the vicinity of southern Cook Inlet. Southeast winds will pick up ahead of the front, particularly through the mountain gaps in the Kenai and Chugach Mountains (most notably Turnagain Arm). It looks like these gap winds will peak late this morning.
The front will then begin to shift and this shift should loosen up the pressure differences between the fronts allowing for winds to diminish a bit despite the fact that the front will continue to get closer. Be the time the front finally crosses the Kenai Peninsula and Anchorage tonight it will be in a much-weakened state. In the time being, as thanks to some interaction with the exiting low over the southeast Gulf some storm energy will develop out ahead of the front.
Mostly cloudy in Anchorage Friday with early fog. We could see early rain, as well as afternoon rain at times before storms, weaken and rain tapers off later in the day. Temps will fall to 46 degrees overnight with patchy fog at times after Midnight.
Cloudy on Saturday with a high of 61 degrees as well as patchy morning fog. While under partly cloudy skies Saturday night we drop down to 45 degrees.
Looking ahead, Anchorage will be cloudy on Sunday with early patchy morning fog, a 60 percent chance of rain while we warm up to 60 degrees for a high temperature.
Fire Weather: Most of the active fires will see some rain and wind out of this storm system. While the Copper River Basin as a whole will remain drier, it increasingly looks like the Tokaina Fire will see some rain as the front pushes onshore tonight and down-slope winds weaken.
