NWS Forecaster Discussion




Southeast Alaska forecast discussion 
National Weather Service Juneau Alaska 
339 PM akdt Monday Jun 29 2015 


Short term...the light rain that we called for yesterday 
afternoon was both heavier and more expansive than we thought. For 
the quantitative precipitation forecast which turned out to be the surprise of the day, the GFS 
beat the ecwmf, the NAM, and nam's high res children, nmm and arw 
who called for much less rainfall. The GFS also beat the Gem, who 
called for a little too much. As the GFS several days ago took the 
lead with the current shortwave over the Panhandle by calling our 
attention to it when all other models were indicating a mere kink 
in the flow over the North Pacific...it deserves praise. Rainfall 
amounts originally predicted to be limited to a half-inch or less 
around the Panhandle reached nearly 1 inch for Juneau with 
anywhere between a quarter to a half-inch for 
Sitka...Petersburg...Wrangell...and Klawock with much lighter 
amounts over Lynn Canal, Gustavus, and Ketchikan. 


The shortwave aloft brought in some terrifically moist air over 
southeast. Dewpoints this afternoon over the southern Panhandle 
have surpassed 60 degrees and are very near 55 for the north 
contributing to a very muggy feeling. This low level moisture may 
briefly ripen instability late this afternoon and this evening, 
but as a ridge builds from the east this moisture will be 
increasingly capped so we are not too concerned. 


As one wave exits this afternoon into Canada...rain will quickly 
diminish for communities against the Coast Mountains where the 
rain is mainly falling currently. A weak front will approach the 
northeast Gulf through Tuesday and will bring a greater 
likelihood of rain for Yakutat starting Tuesday morning. For the 
northern Panhandle rain chances will decrease overnight but will 
once again rise toward afternoon as the weak front approaches from 
the southwest. The southern Panhandle meanwhile will receive less 
effects from the weak system passing onshore to the northwest, 
thus more confident the weather will be drier from Sumner Strait 
south for Tuesday. 


Whereas we are calling skies mostly cloudy tonight, there could be 
sufficient breaks in the clouds associated with weak ridging aloft 
that will allow patchy fog to develop late tonight over the 
Panhandle, especially given the rain that fell today. Some of it 
could be locally dense, but with short nighttime hours, confidence 
never great this time of year. 


Even as there should be slightly cooler temperatures aloft 
tomorrow...given less rain than today...temperatures should be 
very similar if not slightly warmer than today. 


Used elements of GFS, ECMWF, arw, nmm, and sref for updates. 
Confidence generally good. 


Long term...the ridge of high pressure along Southeast Alaska 
curving back along the coast to central Gulf Coast will hold into 
early Wednesday however developing low moving northeast out of the 
central Pacific and is expected to move inland just south of Cape 
Fairweather Thursday morning. As the low approaches the coast 
expect to see small craft winds of 25 to 30 knots impacting the 
coastal marine zones and may also bring several of the inner 
channel up to to close to small craft level speeds for the marine 
forecasts. Rain will spread inland Wednesday night and taper off 
through Friday night into very early Saturday. The surface ridge 
will be rebuilding over the Gulf behind that low moving through 
and straightening to the weekend. 


The general idea in the longer range of the model solutions 
suggest the ridge will will persist over the eastern Gulf and 
Southeast Alaska. A weak trough extending north from southwest 
British Columbia to lie along the Panhandle outer coast early next 
week has a potential in the long range thinking. Overall the 
extended forecast should be dry with exception of afternoon 
showers from solar heating developing. 


The early portion of the forecast had reasonable agreement between 
the model runs and used a blend of ec and NAM for the wind field 
and the rain areas. Am expecting 1 to 2 inches of rain across the 
northern Panhandle with low passage..with some higher amounts in 
the higher terrain quite possible. Will monitor the situation 
however expect the streams across the region to be able to handle 
the influx of runoff with out issue.
