NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Seattle Washington 
330 am PDT Wednesday Jul 23 2014 


Synopsis...an upper level low pressure system just offshore today 
will produce widespread showers and a chance of thunderstorms over 
western Washington. The low will migrate eastward across central 
Washington tonight producing additional rainfall. Precipitation 
amounts through tonight will be locally heavy...especially in the 
mountains and along the coast. The low will move into southeast 
British Columbia Thursday but wrap around moisture will still bring 
a threat of showers into the area. An upper ridge of high pressure 
will build Friday through the weekend and into early next week. Dry 
and much warmer weather is expected. 


&& 


Short term...an unseasonably strong low pressure system will affect 
the region today through much of Thursday. Various models are in 
good agreement with the basic evolution of the synoptic scale 
pattern the next 24 hours and it will be active. Water vapor imagery 
indicates the closed upper low center and associated main vorticity maximum 
now centered along 130 west offshore. The trough has become more north/S 
oriented and is expected to become somewhat negative tilt as it 
slowly moves toward the coast today. This is turning the flow more 
southerly and is increasingly diffluent aloft over Washington. Strong vorticity 
advection coupled with the 85+ knots jet shifting overhead by later 
this morning will increase vertical motion dramatically. In 
addition...precipitable water on the 00z kuil sounding was already 
near an inch and a Plum of 1.5 inches seen on the satellite precipitable water 
product is becoming entrained from a source region off the California coast. 
The combination of moisture and strong dynamic lift will produce 
widespread showers today with categorical probability of precipitation indicated. 


At 230 am radar was already picking up some lightning strikes over 
the Cascades of Snohomish County. The upper level forcing increases 
ahead of and near the low center which supports a chance of thunder 
in the forecast through this evening. Radar also shows a slug of 
moderate rainfall expanding over western Oregon which will be the first 
round of appreciable rain as it reaches western Washington over the next few 
hours. Additional short waves riding northward through the area will 
maintain bursts of moderate or heavier rainfall at times. Mesoscale 
models including the NAM-12 and wrfgfs tally up .50 to .75 inches 
across most The Lowlands and locally over 2 inches near the coast 
and mountains. This system has the potential to set record rainfall 
over the area. See the climate discussion below. 


Showers will begin to taper over parts of western Washington later tonight and 
Thursday morning. Some models show considerable wrap around moisture 
as the upper low lifts NE into southeast British Columbia. The Post trough 
surface pattern also becomes favorable for convergence zone 
development anywhere from Seattle-Tacoma northward...mainly in the 
afternoon. Some areas south of Tacoma and toward the coast may see 
improving conditions with some afternoon sunbreaks. It will remain 
quite cool with highs only in the 60s today and Thursday. 


Split westerly flow aloft dominates the pattern Thursday night...then 
upper heights start to build on Friday making it the transition day 
toward dry and warmer weather. Highs will reach the 70s with partly 
to mostly sunny skies by afternoon. 


Long term...upper level high pressure amplifies over the northern 
rockies and interior Pacific northwest. Models show rising heights over western Washington 
through the weekend but the ridge axis remains far enough inland to 
prevent any strong offshore flow from developing. Instead...it looks 
like a nice gradual warm up to the 80s. Some models such as the 
European model (ecmwf) indicate the ridge could expand far enough west to induce a 
thermal low over western Washington and even warmer temperatures. This is rather 
uncertain this far out but above average temperatures appear likely 
with dry conditions. Mercer 


&& 


Climate...there have been 23 July days with 0.50 inches of rain or 
more since records started at sea-tac in 1945. Only 3 of those days 
have been since 2000...0.65 inches on July 16th 2001....0.60 inches 
on July 20th 2012 and 0.58 inches on July 7th 2002. The record for 
the wettest July day at sea-tac is 0.85 inches on July 13th 1981. 
The wettest July day on record in Seattle is 0.98 inches on July 5th 
1897 when records were kept at the federal building downtown. Felton 


&& 


Aviation...upper level low about 200 nm west of khqm at 12z moving 
east today. The low will move inland tonight. Southerly flow aloft 
today becoming light tonight. Air mass somewhat unstable with 
increasing moisture today. 


Satellite imagery and Doppler radar shows long band of showers from 
near Mount Baker to North Bend Oregon at 10z. This band will slowly 
move east this morning. As the low approaches later this morning 
into this afternoon showers will become more widespread. Isolated 
thunderstorms are possible throughout the day. Ceilings at or above 5000 
feet will lower later this morning into this afternoon down to 
1000-2000 feet with the increasing shower coverage. Some improvement 
tonight as the low moves overhead. The low will move off to the 
northeast early Thursday morning but wrap around moisture on the 
backside of the low will prevent ceilings from rapidly improving 
until Thursday afternoon. 


Ksea...ceilings 6000-8000 feet lowering down to 1000-2000 feet late 
morning/early afternoon as the shower activity increases. 
Thunderstorm chance at the terminal too low to put in the taf at 
this point. Some improvement in the ceilings tonight. Light winds 
this morning becoming southerly 10-15 knots this afternoon into the 
evening hours. Felton 


&& 


Marine...a weak 1015 mb low will remain over the coastal waters 
today then dissipate tonight. With the low dissipating the low level 
onshore flow pattern will redevelop tonight with Small Craft 
Advisory winds possible over the most of the waters. Onshore flow of 
varying degrees will continue Thursday into the weekend with high 
pressure over the coastal waters and lower pressure inland. Small Craft 
Advisory westerlies in the central and eastern Strait are likely 
each day late in the day with Small Craft Advisory westerlies over 
the northern coastal waters on Thursday. Felton
