NWS Forecaster Discussion

Southeast Alaska forecast discussion 
National Weather Service Juneau Alaska 
525 am akdt Tuesday Sep 1 2015 

Short term...low pressure near Dixon Entrance is still causing 
showers over the southern Panhandle this morning...but they are 
diminishing a little sooner than expected for the rest of the 
area. Flow has turned offshore on the backside of the low...helping 
to decrease showers and clouds due to downsloping/shadowing 
effects. Convection is still a possibility near the low center 
this morning...but the few lightning strikes detected overnight were 
south of our area. Some of the showers will still be heavy at times 
early on. 

The pressure gradient between high pressure in the Yukon and the 
low to the south increased overnight and north winds at Eldred 
Rock spiked up to +30kt. North-northwest interior passes/channels will see 
the strongest winds today with many marine areas reaching small 
craft level. However northeasterly passes are a little lighter this 
morning...for example Lynn Canal winds are blowing out of the 
chilkat valley instead of Taiya Inlet/Skagway. A few places over 
the central Panhandle have had some fog this morning...but the 
north winds are bringing in dryer air and should help to scour 
out any remaining showers/fog fairly early on. 

Models were in good agreement with the northerly pressure gradient 
and diminishing probability of precipitation. Used mainly the European model (ecmwf) and Gem to increase 
the pressure gradient slightly then adjusted speeds upward a bit 
more through north-S Inner Channels. Increased the diurnal temperature 
range between maximum/min for expected fewer clouds...with several 
locations falling below 40f early Wednesday morning. Forecast 
confidence is above average. 

Long term...upper trough will drift east away from the area for Wednesday- 
Thursday. Upper ridge will drift eastward across the Gulf but slowly flatten 
Wed-Thu. A shortwave trough will drop southward across the southern Panhandle 
Wednesday-Wednesday night. A complex system will move into the Gulf for late 
Thursday into the weekend. Used a blend of the 00z gfs20 with European model (ecmwf) for 
Wednesday-Wednesday night...then blended European model (ecmwf) with previous forecast for Thursday. 
Rest of the period was mostly left as is except did continue 
upward trend in probability of precipitation for the weekend. 

For Wed-Thu...most of the area will see plenty of sunshine under a 
deep layer northerly flow. The southern area will likely see more clouds Wednesday 
afternoon and night as shortwave moves through that area...and some 
showers are possible especially in the Hyder area. With most areas 
seeing decent amount of sunshine/clear conditions...have increased 
diurnal temperature ranges a bit for most of the area...with maximum temperatures 
boosted a few degrees in many areas...while the normally colder 
areas had min temperatures lowered some for Wednesday night. Limiting factor in 
the nighttime temperatures will be wind...with mainly the northern and central 
areas seeing decent northerly flow. Strongest winds will be around Lynn 
Canal with Small Craft Advisory level winds expected Wednesday and Wednesday night...but those 
will diminish Thursday. 

For Friday into the weekend...looking more likely that rain will 
move back into the area. Models still differ on details of systems 
moving into the area...but generally agree that precipitation will move 
into the area sometime Fri-Sat. Have boosted probability of precipitation to likely for 
mainly the weekend time frame...and if latest model trends 
hold...Friday may need higher probability of precipitation as well.

Marine...Small Craft Advisory for pkz012-013-022-031-032-041-042. 
Small Craft Advisory due to seas for pkz043.
