Southeast Alaska forecast discussion 
National Weather Service Juneau Alaska 
245 PM akdt Tuesday Apr 22 2014 


Short term...upper low remains over the Alaska Gulf and Panhandle 
through Wednesday. At the surface weak are of high pressure over 
the Alaska Gulf with an inverted trough over the Panhandle producing 
weak gradient. An short wave moving in from British Columbia into 
the southeastern Gulf this afternoon will track northward while 
it extends to the west by Wednesday morning reaching the 
northeastern Panhandle by Wednesday afternoon. 


Scattered rain showers and increasing cloud cover will extend 
northward with the advancing short waves followed by some 
clearing skies over the southern Panhandle late tonight. Fog 
development is possible over the southern regions late tonight 
due to these clearing skies. Not much in the wave of precipitation 
accumulation from this weak wave. There will be less diurnal 
temperature range with the increased cloud cover keeping 
overnight lows a bit warmer tonight and highs slightly lower for 
tomorrow. 


Issue for winds today is the northerly and westerly wind flow v 
sea breeze development for some locations. The Juneau westerly 
sea breeze is in phase with the flow pattern while Skagway 
southerly sea breeze is in opposition. At this time the high thin 
stratus over the northern Panhandle was not enough to limit the 
afternoon southerly sea breeze development there. Winds will 
shift as the short waves track northward tonight into Wednesday, 
but overall speeds will be less than 15 kts. With increased cloud 
cover for Wednesday not expecting any sea breeze. 


Main model differences were with the timing of the British 
Columbia wave. NAM was the slowest and more of an outlier 
compared to the ECMWF/GFS/Gem. European model (ecmwf) was maintained good run to 
run consistency so remained model of choice. There were only 
minor differences with the 12z model runs so changes to the 
inherited forecast package were limited. Forecast confidence is 
above average. 


&& 


Long term...models are in general agreement through Friday 
evening with a weakening upper level shortwave trough moving 
northward across Southeast Alaska through late Thursday...followed 
by generally dry air mass expands from the south. A weak inverted 
trough of low pressure will move over the southern Panhandle late 
late Thursday night into Friday...bringing clouds and scattered 
showers. Refreshed the inherited forecast package with the 12z run 
European model (ecmwf) and NAM. The resultant changes are small and mostly cosmetic 
touches over pressure and wind fields. 


Scattered showers across the northern area Wednesday night will 
become isolated on Thursday as the dry weather continues to 
expands northward. Decreasing clouds and warming trend will Grant 
the Panhandle pleasant weather on Thursday. Relaxed pressure 
gradients will prompt no significant winds across Southeast 
Alaska. Increasing clouds again over the southern areas with 
scattered showers will cool down temperatures a bit on Friday. 


Model spreads become larger over the weekend into next week as 
another upper level shortwave trough tries to move northeastward 
across the Gulf...but the main jet stream will remain south of the 
area. Blended the 12z run wpc solutions of European model (ecmwf) ensemble approach 
for the remaining long term forecast periods. 


For early next week...the 250 mb jet stream associated with the 
next deep sharp upper level shortwave trough will curve southward 
over the western Gulf and turn to north across the eastern Gulf 
and the Panhandle Tuesday and Wednesday. As the upper level 
pattern shifts from near zonal flow to meridional...upper level 
dynamics will bring Southeast Alaska a series of disturbances 
originating in sub-tropics. This can be translated for a 
significant warming next week. Due to increased 
uncertainties...predictable surface features are difficult to Pin 
Point but increased clouds and probability of precipitation mainly over the southern half 
of the Panhandle.
