Southeast Alaska forecast discussion National Weather Service Juneau Alaska 358 PM akdt Friday Jul 31 2015 Short term synopsis...a weak upper level trough extends from the Yukon territory to the far southwestern Gulf of Alaska. The pattern allows moist flow aloft much of the Panhandle but with northerly an drier flow aloft over the Yakutat area. This trough will very slowly give way to and upper ridge building into the Yukon Sat afternoon and evening which will also build a surface ridge over the central and eastern Gulf. && Short term...at this writing...Juneau Hoonah Haines Skagway port Alex Wrangell Klawock and Annette are raining. Not much wind. All less than 15 knots. && Aviation... trapped low level moisture plus rain will cause lots of mvmc and even isolated imc conds late tonight and early Sat. Wind in some locations will mix enough not to get the fog and scud. && Marine... a ridge building into the Gulf is always a concern for westerlies and in this case some north wind in the channels. Models typically underestimate the westerlies from the surface ridge so upped the wind speed a couple of knots. No big swell outside but westerlies do have a long fetch for wind waves outside waters. && Fire weather...none. We are still soaked and temporarily suspended our text products which can resume if we ever get drying again. Even a day or two of drying will not get the fuels dry enough here. && Hydrology...toned down the quantitative precipitation forecast on these forecasts as per the previous shift. Most gauges are trending downward at the moment but a handfull are trending up due to local rainfall. Due to the wet pattern we have to watch carefully. Biggest problem child is the taiya as per much of this Summer forecasted to get near action stage Sunday night. && Long term...models still indicating a large upper level trough extending west-southwest from the NWT of Canada to a location south at the start of the extended range forecast period. Models still spinning up two upper lows out of this trough by Sunday morning but diverge early on with the track of both features. Generally, GFS is more progressive with both, as well as with the induced upper ridge that forms in between them. Model divergence at the surface first manifests by early Tuesday morning, with the slower European model (ecmwf) maintaining the vertically stacked feature over the southern Panhandle with widespread showers over much of Southeast Alaska. Current forecast, while not as heavy handed with the probability of showers or the quantitative precipitation forecast amounts, shows a preference for the European model (ecmwf) solution and lower confidence in the GFS solution, which differs significantly from recent previous model runs. Same thinking expresses by wpc in their discussion today. In either solution, and in the current extended range forecast, winds remain below small craft levels except for brief periods late Sunday night and Monday night over northern Lynn Canal. Overall forecast confidence limited to average. && Ajk watches/warnings/advisories... public...none. Marine...none. && $$ Jc/fritsch Visit US at http://www.Weather.Gov/Juneau
