Southeast Alaska forecast discussion...corrected National Weather Service Juneau Alaska 408 PM akdt Thursday Mar 26 2015 Short term...rain showers are the rule of the day across the Panhandle in the wake of yesterday's front. Satellite and radar images this morning showed an organized band of showers moving through the Panhandle associated with a upper short wave trough that was embedded in the general flow. Some of these showers turned out to be moderate to heavy in strength based on observations from Sitka, Angoon, and Klawock. There is also a bit of wind associated with it as well with Juneau gusting to 20 knots this afternoon. That trough will continue to push NE into Canada this afternoon and evening taking its wind and heavier showers with it. Into tonight and tomorrow, forecast remains rather quiet with general S to SW flow of around 20 knots continuing across the Gulf. Showers will continue to be blown into the Panhandle as temperatures aloft remain cool enough, around -25 to -30 c at 500 mb, to spark convection off the warm ocean water. The higher and better orientation of the terrain of the northern Panhandle will result in more clouds and rain there then in the southern half of the Panhandle. So the highest chances of rain and greatest cloud cover has been placed there. The lower amount of cloud cover over the southern Panhandle however could allow some fog to form overnight so I have placed some patchy fog for the southern Panhandle for tonight and early tomorrow. No obvious short wave troughs embedded in the flow for the next 24 hours though there is a very weak feature currently west of 140w that will move through late tonight. That feature could organize and enhance the showers just enough for some more frequent and/or heavier showers but it will not be that noticeable. Only mention of snow will be on the upper reaches of the Haines and Klondike highways where an inch or two of snow could accumulate overnight. Likewise winds are not that significant. Highest winds over the next 24 hours are occurring Thursday afternoon with the trough that is moving through. Winds will remain mostly south and will calm down this evening and remain low through Friday afternoon. The only hazards are mainly due to continuing high seas in the Gulf from high SW swell. The European model (ecmwf) initialized the best of the various models today correctly placing most features in the right places compared to satellite images. The other models were not too far behind though and were decent second and third choices. Decided on using the European model (ecmwf) and the NAM for primary guidance for the next 24 hours. Long term...brief ridging behind the outgoing system will be pushed inland as the next weather front will move across the Gulf of Alaska and into the Panhandle on Saturday. Gale force winds leading the way will make the coastal areas gusty on early Saturday with the front moving though. Have just mentioned gusts 35 miles per hour for southern 23...and zones 27 and 28. Went with a blend of models today using the NAM and European model (ecmwf) for adjustments to the forecast. Through the Middle Range of the forecast think most of the changes were small ... though I may have slowed rain onset briefly for Saturday. Due to the positioning of the low and front think the winds for northern Panhandle may be trickiest. Did not swap the Lynn Canal around until I knew the front was through.. but Glacier Bay got switched sooner do to a better synoptic flow pattern by roughly a half day. Am expecting some brief heavy rain over the southern Panhandle. Aloft the strong jet is still progressing across the Gulf but is starting to cause the upper trough to push into the broad upper level ridge over western half of North America. By early next week the present trough the one following it will have switched that ridge to a more zonal flow pattern. However the upper level low associated with the incoming storm Saturday will have lifted north and shifted the quasi stationary low from south of the eastern Aleutians to southwest of Kodiak. The jet steam weakens over the Pacific and shift even more south closer to 40 north by early next week. This will cause the stronger onshore flow aimed at the northern British Columbia to weaken resulting in weaker but continued onshore flow for Southeast Alaska. Overall the pattern will be closer to being wet than dry for the upcoming week. No significant systems expected for the week...with one possible exception that one of the operational models where hinting at a stronger system for the southern Panhandle late Monday. Will need to watch this to see how this thinking changes with future model runs. && Ajk watches/warnings/advisories... public...none. Marine...Small Craft Advisory for pkz012.
