Southeast Alaska Forecast Discussion National Weather Service Juneau AK 301 PM AKST Fri Dec 6 2019

SHORT TERM. An upper level ridge will build over the gulf tonight, shifting jet stream level flow out of the NW. This will help the scattered to numerous showers over the central panhandle to weaken some. A surface trough will cause the showers to shift northward through the evening. Most places are cold enough to see a mix, but little accumulation is expected.

Through Saturday night the upper level ridge will shift east over the panhandle and turn flow back out of the W-SW. This "dirty ridge" will allow more clouds and moisture to flow into the northern panhandle, but should be able to hold back the main front over the west-central gulf from making further progress. The warm front portion of the front however, will be able to cause steady rain on Saturday to become moderate to heavy Saturday night in Yakutat. The warm air will cause snow levels to gradually rise through the weekend, resulting in a change to all rain.

The upper level trough/ridge pattern becomes more amplified Sunday night with the ridge sharpening over the panhandle. This will cause the warm frontal rain to be pushed back off the panhandle. The Ketchikan area in particular will be stay dry through the period.

LONG TERM. / Sunday to Friday as of 10 pm Thursday / Ridge axis aloft at 500 mb is pushed east of the Southeast Alaska panhandle by Sunday night but the upper trough to the west is trying to nose further into the western gulf. As it does a long southerly fetch aloft will move to the eastern half of the gulf which will lead to increase onshore flow of warm and moister air.

The flow pattern will have some rain for the central gulf coast, perhaps over to the Icy Bay-Yakutat Bay region on Sunday and as the ridge shifts eastward the increase in clouds over at least the northern panhandle will happen along with a small bump in rain changes. Mid to long range models solution still hanging on to the idea that significant frontal band will spread in around Tuesday and a followup around Thursday. Will need to keep a watch and monitor this situation as it develops.

With the overall southerly flow pattern, temperatures should remain above average for the season. And no strong wind events is expected through the week.

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.
