LONG TERM FORECAST (Days 4 through 7)
A low digs into the Gulf of Alaska bringing locally heavy rainfall to the Prince William Sound region Wednesday. Current guidance on the timing and exact location of the low crossing the state remains low but confidence remains high of a change to an overall wet pattern for most of Southcentral next week. Persistent southwesterly flow behind this low will continue to bring weak fronts through Southwest Alaska into the middle of next week. Confidence of a late-week low moving through the Bering Sea continues to increase despite differences in the heaviest rainfall location, strongest winds and overall onshore timing of its front.
AVIATION
PANC...Ceilings aer expected to remain just above MVFR conditions this afternoon and then improve a little through the evening as a southeasterly Turnagain Arm wind moves over the terminal and moderates some of the low level moisture that has been moving up Cook Inlet. Winds should peak overnight into early Saturday morning at the same time that the steady rainfall moves into the area. Both ceilings and visibility may drop into MVFR conditions in the rain, but the stiff southeasterly winds should help limit the conditions to MVFR. As the rain ends Saturday morning and winds shift more southerly, MVFR ceilings may persist well into the day due to the more moist Cook Inlet air and more stable lower levels of the atmosphere.
