Southeast Alaska forecast discussion National Weather Service Juneau Alaska 325 PM akdt sun Apr 26 2015 Short term...the vertically stacked low over the west central Gulf of Alaska will persist into early next week while slowly weakening. The associated frontal band will have have spread through the Panhandle then arcs back into the eastern Pacific. Through late tonight and Monday a developing wave will move north along the old front but then approach the southern Panhandle late Monday afternoon. The rain across the Panhandle is transitioning over to showers. There is quite a pool of cooler air aloft as 500 mb temperatures ranged as cold as -36 c are moving into the eastern Gulf. This pool of cold air along with the lift from an upper level vorticity lobe rotates into the region about the upper level low. The additional lift will be enough for isolated thunderstorms to develop. They should stay primarily off shore but do expect them to likely graze chicagof and Baranof islands late tonight and early Monday morning. Winds are 25 to 30 out over the Gulf of Alaska and outer coastal regions. A few of the Inner Channels are up to small craft levels but are primarily 20 knots or less. Long term...Sun afternoon WV imagery shows a shortwave trough over the North Pacific rounding the base of an upper low centered over the southern Gulf. Latest model guidance indicates the shortwave will eject NE into the northestern Pacific by 06z Tuesday...and then lift north across haida gwaii by 15z Tuesday. This feature then moves north over the southern/central Panhandle through 00z Wednesday. Deterministic model solutions are subsequently converging on the development of a compact surface low pressure system moving north into the Panhandle with its parent upper trough. The 12z GFS and NAM were faster solutions with the northward movement of the low compared to the 12z Gem and European model (ecmwf)...but the 18z GFS and NAM have trended toward a slower evolution as well. As a result...updated pressure grids reflect a heavier weighting toward the Gem/ECMWF...which yields strengthening north-northeasterly winds during Tuesday morning that rapidly flip to southerly after the passage of the low. Gale force winds appear probable over Clarence Strait as this happens...while northerly small craft winds over Lynn Canal during Tuesday morning/afternoon will become southerly small craft winds Tuesday night. A similar evolution is expected for Stephens Passage as a 30+ knots southerly low level jet spreads north by Tuesday afternoon/evening. In addition...gusts will approach strong wind criteria over akz027-028 as the southerly low level jet develops in the wake of the low Tuesday afternoon. Precipitable water values near 0.8 inch are forecast to be drawn northward with the previously mentioned surface low...which could aid in periods of heavy rain over the southern/central Panhandle during Tuesday. In addition...500 mb temperatures near -30 c will spread eastward across the southern outside waters and Panhandle as the shortwave trough lifts north of the area Tuesday afternoon. Subsequent destabilization will result in the redevelopment of a convective environment...as well as a slight chance of thunderstorms as minor upper impulses move across the area. After Tuesday...model guidance remains in fair agreement with the large-scale upper air evolution through 00z Sat...with differences in the development of an upper ridge becoming more noticeable by sun and Monday. GFS and European model (ecmwf) were used for pop/quantitative precipitation forecast through most of the week. Wpc was then used for pressure and pop guidance 00z Friday and beyond...which was composed of a heavy ensemble blend. && Ajk watches/warnings/advisories... public...none. Marine...Gale Warning for pkz051-052. Small Craft Advisory for pkz021-022-033>036-041>043. && $$ Bezenek/Garner Visit US at http://www.Weather.Gov/Juneau
