Southeast Alaska forecast discussion 
National Weather Service Juneau Alaska 
328 PM akdt Sat may 18 2013 


Short term...a surface low over the northern Gulf near Prince 
William Sound still showing up in the cloud pattern. Otherwise 
across the Gulf is the southern arc of a closed low flow pattern. 
The remains of a front and trailing trough moving across the 
Panhandle these remains are spreading showers across the 
Panhandle through the evening and are expected to taper off 
slowly overnight. Over the main portion of the Gulf are the 
strato cumulus showers initially being fed into the western Gulf 
by the cold air spilling out of the Bristol Bay region. 


A vorticity lobe aloft in the upper flow will be enhancing 
showers overnight and into early Sunday over the northeast Gulf 
Coast. This plus the cold air pool moving in from the west may be 
sufficient to spark some sleet in heavier showers. 


There is some locally windy/gusty winds through the early 
evening... for the Cross Sound area and the northern Lynn Canal 
regions. I expect those to be diminishing some through the 
evening hours. 


Long term...dry through the long range period. Frosty mornings in 
northeast Gulf and north central Panhandle through Wednesday 
morning. High temperatures will be in the 60s starting next Tuesday. 


The start of the long range period will feature diminishing 
showers and clearing skies, as a 1043-mb high pressure builds into 
the Gulf of Alaska. As the high pressure builds into the Panhandle 
Sunday night, winds will be shifting to northerly and westerly 
directions. This will bring in drier but cooler Continental polar 
airmass into the Panhandle. With clearing skies, effective 
radiation cooling will allow temperatures to drop into the upper 
20s to low 30s from northeast Gulf into north central Panhandle. 


With mostly sunny skies over the Panhandle on Monday, high 
temperatures should reach the middle to upper 50s in the afternoon. 
Clear skies are expected Monday night and Tuesday night. Thus, 
northeast Gulf and north central Panhandle will be under the 
threat of frost once again for both nights. The airmass will be 
moderating with time. By Wednesday night, frost should be out of 
the area. 


With mostly sunny skies, daytime high temperatures should be in 
the 60s for most of the Panhandle starting Tuesday. The work week 
should also remain dry, with precipitation confined to east of the 
coast mountain in British Columbia. 


Forecast confidence remains above average through the long range 
period. Utilizes guidance from European model (ecmwf)/wpc to refresh the forecast 
package. 


Ajk watches/warnings/advisories... 
public...none. 
Marine...Small Craft Advisory for pkz012-013-022. 
Small Craft Advisory due to seas for pkz041>043-051-052.
