Southeast Alaska forecast discussion National Weather Service Juneau Alaska 222 PM akdt Tuesday may 26 2015 Short term...upper trough over the Gulf is in process of closing off aloft. The resultant upper low will drift east into the Panhandle late tonight and Wednesday. High pressure will build over the Gulf later tonight and Wednesday in response to upper ridge building northward into that area. Used blend of the 12z European model (ecmwf)/Gem/NAM models for the forecast through Wednesday. Main forecast concerns will be precipitation potential and winds. Right now...there is a band of precipitation just offshore the central coastal area associated with middle-level front and positive vorticity advection ahead of upper trough. Some precipitation is also breaking out just ahead of this band right along the central coast. Expect the precipitation band to swing NE across most of the northern half of the Panhandle this evening...then settle along the Coast Mountains from papg-pajn overnight as upper low moves onshore. This will generally persist through most of Wednesday...but a developing precipitation band over northern British Columbia will likely drift southwestward into the north-Central Area late in the day. Did limit probability of precipitation to likely though as precipitation band may thin out some as it comes ashore into a slightly drier airmass already in the area this evening...then precipitation may be more spotty in nature later tonight into Wednesday. Longest period of likely probability of precipitation will be around the pajn area where best upslope and lift will persist. Southern area looks like it will only see a few sprinkles later tonight and Wednesday...thus kept probability of precipitation on low side there. The paya area will probably get clipped by the band moving onshore early this evening...then precipitation threat will diminish there later tonight and Wednesday but not completely disappear. As for winds...they will be on the increase over the Gulf as weak to moderate cold advection and building surface high will tighten pressure gradient. Expect band of Small Craft Advisory level west-northwest winds Wednesday over the northern and eastern Gulf. Some diurnal enhancement to the winds will be occurring this evening over the Inner Channels...with Small Craft Advisory level S winds likely for far northern Lynn Canal and 15-20 knots in most other Inner Channels this evening. They will diminish later in the evening before stronger winds behind front aloft come in late tonight and Wednesday. Will likely see Small Craft Advisory level westerly winds in Cross Sound and southerly winds in northern Lynn Canal Wednesday...with 15-20 knots over much of the remaining Inner Channels. Otherwise...marine layer will be lifted by the approaching front which should raise cloud ceilings for the early evening...but they will lower again overnight tonight. Do not think clouds will be as low however as boundary layer will be deeper and allow for better mixing. Long term...models remain in fair agreement for an upper level low over the central Panhandle Wednesday night slowly fills and drifts southeastward to the southern British Columbia through Friday evening. Surface high pressure will continue to dominate across the Gulf and an inverted surface trough of low pressure will persist east of the coast mountain range. A middle level frontal passage associated with the upper low will continue to disorganize as it moves southeast Wednesday night into Thursday morning. The inverted surface trough will maintain likely probability of precipitation over the east central Panhandle Wednesday night...then move south to the southern British Columbia by Thursday afternoon. Refreshed the inherited forecast with the European model (ecmwf) and Gem for their good consensus through Friday evening. Dry and seasonably warm weather will return to Southeast Alaska late Thursday and continue through early next week as the upper ridge continues to build north and surface high anchors over the Gulf. Model differences become larger over the weekend an upper level shortwave trough develops over the northern Canada and slowly digging southwestward. Used the wpc ensemble guidance for the remaining long term periods. Expect increasing rain chance over the northernmost Panhandle and along the coast mountain range from Sunday. Near small craft level west to northwest winds will affect the southern outside waters Wednesday night and again late Friday. No significant winds are expected across the Inner Channels. && Ajk watches/warnings/advisories... public...none.
