Southeast Alaska forecast discussion National Weather Service Juneau Alaska 331 PM akdt Monday Jul 6 2015 Short term...biggest issue over the next 24 hours is the extent of the marine stratus tonight and Tuesday morning. This morning the low clouds and fog made it as far east as Sisters Island in Icy Strait. Expect a similar scenario tonight but concerned it could make it a bit farther inland as the ridge begins to weaken and tip over due to shortwave energy over the central Gulf. Did bring it a little farther inland into Peril Strait and Tenakee Inlet. Also included some drizzle along the outer coast. As the ridge begins to weaken on Tuesday, this will allow more mainly high cloud cover to spread over the Panhandle on Tuesday. A weak area of low pressure associated with the energy mentioned above will push a band of rain into the Yakutat area by midday Tuesday. With weak forcing am expecting rain to be on the lighter side. Very warm temperatures across Southeast Alaska this afternoon with many locations across the southern Panhandle well into the 80s. Some locations such as Hyder will likely reach 90 degrees this afternoon. Slightly cooler conditions can be expected on Tuesday but temperatures are still expected to get into the low 80s over the southern Panhandle with 90 degrees possible again in Hyder. Over the northern Panhandle cooler air aloft combined with increasing cloud cover will lead to highs being 5 to 10 degrees cooler than today. Winds will follow the same general diurnal trends as the previous few days. Small craft winds near Cross Sound and Cape Decision will weaken later this evening as solar heating subsides. Lighter winds will be felt overnight with sea breezes picking up again Tuesday morning. However with cooler temperatures and increasing clouds, sea breezes will likely be a bit weaker than today. Mainly used the hi-res nmm for updates to the forecast through 24 hours. Changes were small and generally limited to local effect changes. Forecaster confidence is average through Tuesday afternoon. Long term...while the Panhandle will will undergo a shift in weather pattern at the start of the long range the upper level features don't show as much change through the week. Not counting the trough that moves across the northern Gulf Tuesday evening the 500 mb pattern keeps some form of a low over the Bering Sea, a high pressure ridge over the Alaska Gulf and a second low located over northern Canada. However each of these main features do move enough to make some uncertainty in the extended forecast. The Tuesday night trough crosses the Gulf and moves over the Panhandle through the day on Wednesday with high pressure rebuilding over the Alaska Gulf. With weak forcing along the wave believe precipitation will hit the northern Panhandle coast but shear apart and not make it much further inland, so have kept only chance probability of precipitation. Any rain fall that does make it should be light. Temperatures will drop with the increased cloud cover and diminishing 850 mb temperatures but as the ridge rebuilds on Thursday seeing 850 mb temperatures increase again and have some potential for clear breaks developing, especially over the southern Panhandle. Warmed up temperatures there just a bit for Thursday and Friday. What this late week pattern is lacking compared to today's set up is the inverted trough extending over the Panhandle, so high will only be in the 70s. Question as the ridge rebuilds over the Gulf will be if marine layer forms and if the onshore flow move that layer all the way inland. With the exception of northern Lynn Canal which will remain at small craft levels Tuesday night due to the tight pressure gradient, winds will be less than 20 knots Tuesday and Wednesday with overland winds becoming light. Wind direction for the central Inner Channels was bit tricky Tuesday, as pressure gradient would keep them more southerly, but flow around the ridge would be northerly. By the weekend there are indications of another shortwave crossing into the northern Gulf Friday night into Saturday with a more substantial surface low potentially making it into the central Gulf late Monday. Still bit early to put much confidence in this. Models fell in line with the 12z runs and had good agreement for the pressure pattern through day 6. Used a blend of the 12z European model (ecmwf)/Gem for pressure as the NAM was bit off on short wave location and the GFS had some issues over the Panhandle. Most model pop fields seemed a bit high so kept with inherited fields. Overall changes were minor with a few direction tweaks due to the updated pressure field. Forecast confidence is average. && Hydrology...above normal temperatures will lead to a rise in the taiya river during the afternoon and evening hours over the next couple of days. The river will then follow the usual diurnal cycle of falling during the early morning hours. At this time the river is expected to crest around 16 feet both Tuesday and Wednesday afternoon. This will continue to be monitored through middle week before cooler temperatures move into the area. && Ajk watches/warnings/advisories... public...none.
