Southeast Alaska Forecast Discussion National Weather Service Juneau AK 552 AM AKDT Sat Jul 11 2020

SHORT TERM. A surface low about 250 nm west of Haida Gwaii will continue to weaken as it drifts east towards Haida Gwaii. It dissipates as it moves over the island Saturday afternoon and evening. The moisture streaming about low has been impacting mainly the southern panhandle. while scattered showers fall north of Frederick Sound. Portions of the southern panhandle got over 2 inches yesterday, not expecting more than 1/2 to 1 inch today and the heavier rains should be diminishing by noon. Showers should hang on over the southern half even after the low falls apart today, with better improvement overnight. A second small feature will move some precipitation into the Yakutat area by afternoon and think it will last through the first part of tonight then will diminish towards morning. Cloud cover for the northern panhandle could have thin spots in it early Saturday so sunny breaks for portions of the northern panhandle.

A ridge of high pressure will move across the gulf Saturday night and to the coast mountains by Sunday afternoon where it will stall and slow down the first short wave moving from the North Pacific. Expect this front and low to move into the northeast gulf on Monday.

Once the low falls apart south of the panhandle, the flow aloft becomes more westerly even with the ridge approaching so believe the isolated to scattered showers along the terrain will continue through Sunday.

Winds for most part under 15 kt, though Lynn Canal is expected to increase to 20 kt overnight with the ridge approaching the panhandle. Sunday night into Monday the next feature will begin to spread across the with its band of higher winds.

LONG TERM. /Monday through next Friday/ As of 10pm Friday. Monday starts off with a chance of showers in the forecast, but overall the first part of the day looks decent. Then a new system moving across the gulf from the west will cause increasing clouds and POP, but models differ quite a bit on timing and position of that. The 11/00z model runs show the ECMWF is the fastest and the GFS is the still slowest keeping the low over the western gulf much longer while the Canadian is in between. Generally the consensus is still for rain to move in Monday night and for Tuesday to be the most likely wet day of the week. In previous runs the most models were taking a slightly further south track than today, but have kept the focus of highest POP over the south since they will get it with either track. Due to the expected cloudy/rainy weather on Tues, went below NBM/WPC guidance for high temperatures and closer to MOS, but may need to lower them more into the mid 50s.

Once the low weakens and moves through on Wednesday, there are signs of more ridging for the end of the week that could give us some breaks. But there is a lot of uncertainty in this forecast. The GFS brings another low to quickly replace the first and keep showers going and the Canadian generates a low to the south. Model snow levels and temperatures still show a slight increasing trend however, so any sunny breaks should be in the 60s.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
