127 FXAK67 PAJK 291223 AFDAJK Southeast Alaska Forecast Discussion National Weather Service Juneau AK 423 AM AKDT Mon Apr 29 2024 .SHORT TERM...The low that was bringing rain showers to the area continues to move south past Haida Gwaii this morning. In its wake, clouds and some light rain showers remain over the area but high pressure is already building into the area from the west. The clouds and showers will continue to slowly dissipate across the area allowing for more clearing throughout the day albeit slowly. Increased the cloud cover for today though as cloud cover this morning is more widespread than previously thought. With the cloud cover remaining over the area longer, brought down temperatures across the area to account for the increased clouds. Overall though, it is looking like it will be a nice day for most of the panhandle today. .LONG TERM.../ Tuesday to Friday night / Tuesday and Wednesday look to non impact weather days, with a ridge of high pressure moving through the eastern gulf and panhandle leaving an area of high pressure near the north central gulf coast by Wednesday. A low pressure system undercuts the gulf coast area to Southern Haida Gwaii by Wednesday night. A larger low moves from the Aleutians into the northern gulf and the front extends southeast. This front looks like it may be stalled out over the gulf just off the panhandle or just spread into the panhandle early Saturday. && .AVIATION...Very quiet aviation weather today. Main concern is some mid level clouds that are advecting over the area from the east (or developing in place) this morning. Some of these are low enough for MVFR ceilings, mainly in the south and near Yakutat. Otherwise winds are low and VFR conditions are the main rule for the day. && .MARINE...As a ridge builds in the gulf on Monday, a westerly component to winds will gradually take hold, further increasing from clearing skies. East west facing channels such as Icy Strait will likely have enhanced winds up to 15-20 knots during the daytime period. Fortunately, swell in the gulf will be mainly southwesterly, same as incoming winds into the inner channels, which will limiting seas. Low level warm air advection aloft moving southeast along the eastern gulf coast tomorrow morning will bring some enhanced winds to these areas through Monday. Expect the area of maximum winds to move from north to south through Monday and Monday night. && .AJK WATCHES/WARNINGS/ADVISORIES... PUBLIC...None.
