NWS Forecaster Discussion




Southeast Alaska forecast discussion 
National Weather Service Juneau Alaska 
351 PM akdt Monday Jul 28 2014 


Short term...large-scale pattern has changed very little during 
the past 24 hours. Upper trough remains positioned over the 
Gulf...with a ridge extending northward into the Bering Sea and a 
Second Ridge located over western Canada. Two upper impulses are 
observed this afternoon rotating around the larger-scale trough. 
One is poised to enter Southeast Alaska by this evening bringing the first 
round of moderate to locally heavy rainfall. The second impulse 
is currently entering the base of the Gulf trough...and is 
forecast to eject into the central/southern Panhandle during Tuesday 
afternoon. Precipitable water values will remain at or above 1 inch as this takes 
place...thus expect moderate rainfall rates to occur once again 
as forcing for ascent reinvigorates with this second disturbance. 


At the surface...modest area of low pressure will be centered 
over the Gulf through the short term. Meanwhile...a smaller low 
is forecast to lift northward into the southern-central Panhandle tonight as 
the first upper impulse enters the region. In addition...30-40 knots 
low- level southerly jet will strengthen over the southern Panhandle in 
response to the upper disturbance. This momentum aloft is 
expected to mix to the surface over Clarence Strait and aid in 
small craft to possible gale force winds. 


Diurnal temperature range will be limited through Tuesday afternoon 
due to widespread clouds and rain. Updated pressure/winds using a 
blend of the ECMWF/Gem...with manual increase in speeds over 
Clarence Strait in order to take into account strengthening low- 
level slys. Previous pop/sky forecast appeared to be on 
track...thus few changes were made. Forecast confidence is 
average. 
&& 


Long term...this second impulse discussed above currently 
rotating around the base of the trough will push a front through 
the bulk of the Panhandle and bring in a little cooler air 
aloft...thus rain will transition to showers Tuesday night from 
fairweather south. Yakutat will actually become a little wetter as 
the energy lifts northwestward Tuesday before everyone begins a 
trend to drier air as the largescale low begins retrograding to 
the southwest. This temporary jog to the southwest will allow 
skies to part beginning Thursday with some periods of sun likely 
through Saturday for the northern interior Panhandle. Clouds look 
to re-enter the area from the south Saturday morning as the low 
begins responding to a gentle nudge...perhaps by some energy 
diving downstream into Mainland Alaska by the end of the week. 
This will once again bring in chances of rain...mainly for the 
latter half of the weekend. Confidence not as great as last 
package because only the European model (ecmwf) now going wet Bona fide. Gem 
uncharacteristically has sided with the GFS in keeping the 
largescale low in the SW Gulf. Thus trended down the likely rain 
we had from last night to chance over the interior...but left the 
coastal 60 percent probability of precipitation in tact. Models come in better agreement 
early next week as GFS finally indicates the Gulf low being drawn 
northeastward by shortwave progressing across the Brooks 
range. 


Winds look to increasingly become benign through the mid-range. 
Did perhaps get a little excited by adding a small craft for Lynn 
Canal...as the European model (ecmwf) showing gradients rising above 2 mb then...however 
jet was not impressive and continued cloud cover should keep 
mesoscale effects negligible...so this may have been heavy-handed. 
Channel breezes may begin to predominate Thursday as differential 
heating increases. While currently mainly light winds are 
represented for Thursday...models showing a little hint of a 
thermal trough over the southern/central Panhandle perhaps 
increasing winds out of the north/west to 10 or 15 knots. Saved for 
later as models improve agreement. Did violate gradient for Cross 
Sound for Thursday/Friday as a westerly sea breeze should develop. 
While we trended temperatures upward slightly...GFS actually going 
70s for parts Friday, Cross Sound westerlies may need to be 
increased during this time. 


Forecast confidence on good side of average for most issues. 
Relied on European model (ecmwf) as a guide Tuesday night into Wednesday...for late in the 
week preferred GFS/Gem but gradually hedged bets of dry weather 
extending into early part of weekend with a little bit of 
stubbornness from the European model (ecmwf) that it will be wet once again. 


&& 


... Will increase in intensity across the central/southern 
Panhandle through tonight with ceilings/visibility subsequently 
falling as a result. One exception will be Yakutat...which will 
experience the onset of steady light rain late tonight into Tuesday 
morning. 


&& 


... 30-40 knots southerly low-level jet is forecast to reside 
over Clarence Strait tonight...and will aid in small craft to 
occasional gale force winds from 25-35 knots. Elsewhere...pressure 
gradient continues to tighten over Cross Sound resulting in 
sustained Ely winds near small craft strength. Otherwise...northerly 
pressure gradient from Glacier Bay into Lynn Canal and Stephens 
Passage is forecast to flip to southerly by Tuesday afternoon. 


&& 


Ajk watches/warnings/advisories... 
public...none. 
Marine...Gale Warning for pkz036. 
Small Craft Advisory for pkz022.
