Southeast Alaska Forecast Discussion National Weather Service Juneau AK 543 AM AKST Thu Dec 12 2019
SHORT TERM. The weakening vertically stacked low in the western half of the Gulf of Alaska will drift north about 100 mn east of Kodiak Island to be near southern Kenia Peninsula Friday morning. Another low Friday seem to try and work its way into the southeast gulf by late Friday is being broken down into just a trough. High pressure over western Canada holding most of the weather systems from progressing eastward through the panhandle.
Expect rain/showers to continue into Friday, and then will start improving with shower activity decreasing mainly over the south. This is duee to the low moving further away and weakening. Showers will persist better along the norhteast gulf coast.
Even the northeast improves Saturday as a large flow moves into the southern Bering sea and then the far western gulf on Saturday.
The northern Lynn Canal may bring some exciting weather over the next 24 to 48 hours. Am thinking there may be sufficent cool air around to allow a few inches of snow to fall along the Haines Higway to the border, and then continue into Friday. This all depends on the temperatures cooling and sufficient moisture reaching the area.
LONG TERM. /Saturday through Thursday night/ . The extended range forecast begins with an upper ridge moving east over the Panhandle while a low moves slowly eastward into the far western gulf. By Monday, the low in the gulf will swing a front through the region pushing the ridge to the east. Flow will become onshore next week as several systems rotate around a parent low in the Aleutians bringing multiple rounds of precipitation to the Panhandle. There are still model discrepancies of the timing of each system moving into the region. What does appear to be relatively certain is wet weather will persist through most of the coming week.
Guidance does indicate that there will be low level cold air advection from the west through the weekend. The forecast reflects model guidance by showing a cooling trend through Sunday across the Northern Panhandle with temperatures remaining around average for much of next week.
No major changes were made to the long range forecast tonight as it is hard for models to pin down the exact timing of each system rotating into the region. Sunday appears to be the driest day over the next week as a ridge will be over the Panhandle. A front moves in on Monday increasing the chance for precipitation. P-type could be an issue for areas in the Northern Panhandle as colder air at the surface may be hard to scour out by the time the precipitation moves in. Since there are still inconsistencies with the models, a slight change to one aspect of the forecast will greatly affect the rest of the forecast. Temperatures have an effect on snow levels, which in turn, have an effect on the probability of snow rather than rain for the next week. Current thinking is that the northern Panhandle has the best chance at seeing frozen precipitation, especially along the highways. The southern Panhandle is expected to see predominantly rain. Fortunately, several days remain before this becomes an issue with impacts on the public, so it can be studied closely by multiple shifts.
Overall long range forecast confidence is below average.

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.
