SHORT TERM FORECAST SOUTHCENTRAL ALASKA (Days 1 through 3)

A cold and relatively deep upper level trough over central Alaska will drift slowly south into Southwest Alaska over the forecast period while slowly expanding in area. Meanwhile, easterly low level flow is already building north of a broad low in the north Pacific that will move into the Gulf over the weekend. For the forecast expect more of the same, areas of light rain showers today with gap winds continuing through the Knik and Turnagain Arms as well as the Copper Valley. Over the weekend the gap winds will for the most part let up as the coastal ridge weakens and the gradient goes back down the Inlet. For precipitation, the Gulf system has trended farther to the north and west, meaning higher chances for rain throughout Southcentral Saturday and then again on Sunday when a different shortwave moves in from the southwest. All in all expect more dreary, wet and breezy "fall" weather to continue.

AVIATION

PANC...Light rain showers will linger through this evening. Gusty southerly winds will continue through this afternoon before weakening. Winds will flip to northerly later Friday morning. VFR conditions expected.
