Severe Weather Alert Descriptions

 Public Information Statement  Statement as of 1:00 PM PST on May 22, 2015


... El Nino growing stronger...

The National weather services climate prediction center (cpc) issued
a couple of key releases last week regarding the evolution of El
Nino. El Nino is gaining strength.

Here are two presentations that highlight the current status and
outlook on el ninos evolution through at least the rest of this
year. (Disclaimer - mid year evolution of El Nino southern
oscillation (enso) tends to vary widely and the key trend for the
coming winter begins to show more clearly by September.)

Yet the trend of late is enough to ensure everyone is aware of this
situation as we move through this Summer and into this winter.

Below are the two presentations updated this past week by the CPC.
There is a lot of science in them. The bottom line is El Nino is
gaining strength and looks to be in place into this coming winter.

Latest weekly enso status... evolution and prediction presentation

Http://www.CPC.NCEP/NOAA.Gov/products/analysis_monitoring/lanina/enso
_evolution-status-fcsts-web.Pdf

The latest CPC seasonal outlook for Washington state issued
yesterday continues to show good odds on warmer than average
temperatures and tipping the odds to drier than normal conditions
this Summer and into this winter. If these trends hold true... this
outlook is not good news for the wildfire season statewide and then
a good likelihood of another lower than average mountain snowpack
this coming winter.

The National Weather Service Seattle drought information statement
issued this morning highlights some key elements. Much of the lower
and mid Elevation Mountain snow pack has already melted. April
through mid may precipitation has been much below average. River
stream flows are well below normal. Washington governor Jay inslee
recently extended the drought declaration to all of the state. See
http://www.Wrh.NOAA.Gov/sew/Hydro/seadgtsew for the complete drought
statement.

Unless much wetter weather develops soon... the entire state will
have a much higher risk for wildfires. Everyone needs to be careful
regarding any burning materials or fireworks out of doors this
season. If the warmer and drier outlook for this winter develops...
then water supplies may be more limited heading into the Summer of
2016 along with a heightened wildfire threat.

NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Seattle Washington 
322 PM PDT Friday may 22 2015 


Synopsis...a large surface high offshore will maintain moderate to 
strong low level onshore flow over western Washington through middle 
next week. This will maintain the pattern of morning clouds with 
varying degrees of partial afternoon clearing. Weak low pressure 
aloft will bring a chance of showers...mainly over the mountains 
afternoon and evenings. 


&& 


Short term...the large NE Pacific surface high will be doing its 
dominant thing for the next week...maintaining moderate to strong 
onshore flow across West Washington. The onshore flow direction will be 
predominantly SW so low level marine moisture will have an easier 
time spreading inland up through Puget Sound sound. Skies will remain 
mostly cloudy which will keep temperatures close to normal may 
ranges. There will probably be varying degrees of partial clearing 
from day-to-day but overall skies will remain mostly cloudy. The 
marine layer is deep enough and with a weak upper level trough over 
the offshore waters it seems reasonable to hang on to the chance of 
drizzle for the west part. 


The main issue this afternoon has been the showers and isolated 
thunderstorms over the Cascades headed very slowly in the direction 
of The Lowlands...and showers over the Olympics moving north and 
crossing the Strait of Juan Delaware fuca zones. There is still time for 
the showers to weaken and dissipate before reaching The 
Lowlands...but I will be conservative and expand the chance of 
showers over more of The Lowlands this evening. 


The weak upper level trough just offshore will shift over West Washington on 
Saturday. This will shift the middle level flow over West Washington from east-southeast to 
SW over the coast and S over the interior. The main effect should be 
to restrict convection to the Cascades rather than have cells 
drifting west over The Lowlands. An upper level low along the b.C. 
Coast today will drop down over SW b.C. Sunday afternoon...shifting 
the middle level flow to west over West Washington. This should end the threat of 
thunderstorms for the Cascades...although there could still be some 
showers right along the crest. 


The 12z European model (ecmwf) takes the low southeast over East Washington Monday afternoon while the 
18z GFS drops it down over West Washington. The 12z GFS was similar to the 
European model (ecmwf) so it appears there could be some uncertainty over the next 
couple of days regarding where the low GOES. The European model (ecmwf) track should 
keep most showers over the Cascades and most of The Lowlands 
dry...while the GFS would spread showers across more of The 
Lowlands. The forecast follows the 12z GFS and European model (ecmwf). GFS middle-level 
lapse rates suggest the air mass will be too stable for 
thunderstorms. Kam 


Long term...GFS/ECMWF take the upper level low east on Tuesday with north 
flow aloft developing over West Washington. This should end any threat of 
showers for The Lowlands and probably the Cascades as well. The 
surface ridge over the NE Pacific will maintain the onshore flow 
pattern next week for mostly cloudy skies...but the flow could 
weaken enough for a bit more afternoon sunshine. Kam 


&& 


Aviation...no major changes to the blocked upper level pattern 
are expected over the Pacific northwest through this weekend. The flow aloft 
will generally be light and variable. The thunderstorms over the Cascades 
will dissipate after 0300 UTC. 


Meanwhile...ceilings mainly in the 1-2k feet range blanketed much of The 
Lowlands this afternoon. The marine layer was quite deep /tops 
were running 5500 to 6 ft/...so not expecting much /if any/ 
improvement the rest of today. MVFR ceilings will persist through 
tonight...although there will be areas of IFR ceilings /500-1k feet/ 
and visibilities 3-5sm mainly over the coast. The Olympics and Cascades 
will be partially obscured. 


Ksea...ceilings should be in the 2-3k range the rest of today...and 
will lower into the 1-2k feet range overnight. MVFR conditions will 
persist through Saturday morning. 


&& 


Marine... 
no significant chances are anticipated in the weather pattern 
through the middle of next week. High pressure will remain offshore. 
This combined with lower pressure inland will result in continued 
onshore flow of varying strength through next Wednesday. 


&& 


Sew watches/warnings/advisories... 
Washington...none. 
Pz...Small Craft Advisory is in effect for the central and eastern 
Strait of Juan Delaware fuca.
