Farther to the south, high pressure has moved into the control the rest of the weather for SE AK. With high pressure controlling most of the weather for the area, winds continue to be relatively light with the strongest winds getting up to gentle to moderate breezes. These conditions are expected to persist tonight before the low moves closer towards Yakutat which will increase the winds coming out of Cross Sound and increase the possibility of showers along the outer coast for tomorrow. With the mostly clear skies overnight though, temperatures are expected to drop this evening bringing near freezing to below freezing temperatures for the Panhandle. For Thursday night, the chance for active weather returns as the odds for precipitation increase across the area. With the cooler temperatures, a mix of rain and snow before switching to mostly rain as warmer temperatures return reducing the likelihood of snow. .LONG TERM.../ Friday through Sunday / Weakening trough falls apart across the north central panhandle as another one lifts towards the southern panhandle. Friday to Saturday will see a front, from a low that forms on a feature from the big parent low in the west central Bering Sea, spreads across the gulf reaching for the panhandle area and then through the area by Saturday night. Late Saturday to Sunday is showing ridging over the gulf to central gulf coast, while an upper level low cutting south of the panhandle helps to pull the front through and southeast, which should result in partial clear, or an end of the shower activity in the northeast gulf coast and northern panhandle. Does look like the break will not be very long in time. Rain snow line Friday and Saturday down to about the Icy Strait Juneau line, and light or no Accumulations are possible before warming later and Friday to Saturday pushes in and changes that region to rain again. Northern Lynn Canal a mix or light snow accumulation although concerned that moisture amounts will not be sufficient for larger totals. At this staying on the lighter end of Snow totals. ( under a few inches. ( under 3 inches ) however if better QPF is available this could be doubled. && .AVIATION...Variable conditions across the panhandle Wednesday night as some clearing in the upper levels is gradually being replaced by low and mid level stratus developing over the inner channels ranging from 2000 to 3000 ft, but AoB 500 ft in some areas. The lowest conditions are in the vicinity of Juneau as well as Gustavus. Low level stratus is expected to last into the morning, gradually expanding to encompass most of the inner channels. Fog however is not expected to be as pervasive, as temperatures in the low to mid 30s generally result in fog frosting out after a period. However, the combination of fog and low stratus moving in overhead could allow fog to persist for longer. For Thursday, a weak trough will bring more moisture to the panhandle as well as a slight increase in winds which will also help to mix out some of the low clouds as it moves through. This will also lead to winds for the southern half of the panhandle to pick up more out of the SE and E by early Thursday afternoon. && .MARINE... Outside (Gulf and Coastal Waters): Showers and gentle breezes continue across the Gulf and outer coast this afternoon as high pressure remains over the eastern portion of the Gulf while a weak low pressure currently sits near Prince William Sound. Winds across the area are expected to remain light across the area headed into Thursday. As the low drifts to the east towards Yakutat, winds are expected to increase out of Cross Sound into the Cape Fairweather area. Even with this low in the Gulf, wave heights are expected to be on a downward trend headed into the weekend with seas being around 4-5 ft Friday morning. This will be a brief break though the next system moves north into the area Friday into Saturday bringing winds increasing towards fresh to strong breezes. Seas are expected to start building towards 8-12 ft at this time. Inside (Inner Channels): Light winds persist across the Inner Channels this afternoon. Winds are expected to shift out of the north as a weak outflow setup is expected. Winds are expected to remain light headed into tomorrow for most places with the strongest winds likely being for the Dixon Entrance/Clarence Strait area and headed towards Cross Sound. Headed into the weekend, winds are expected to towards fresh breezes in response to the the low in the Gulf && .AJK WATCHES/WARNINGS/ADVISORIES... PUBLIC...None.
