NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Seattle Washington 
330 am PDT Thursday Jul 30 2015...corrected time 


Synopsis...a strong upper level ridge will be over the Pacific 
northwest through the weekend. The ridge will weaken Sunday and 
Monday. An upper level trough will move over the area by the middle 
of next week. 


&& 


Short term...a strong upper level ridge over the western U.S. Will 
expand a bit further northward today with 500mb heights rising to near 
5900m. The negative tilt ridge axis extends off the Pacific northwest coast 
with a broad thermally induced trough on both sides of the Cascades. 
Msas mean sea level pressure analysis indicates the thermally induced low has 
shifted just off the coast and both Quillayute and Hoquiam 
currently have light easterly wind. Given the height rises today it 
seems likely the termally induced low pressure axis will remain near 
the coast today...not shifting slightly inland until early to middle 
afternoon. This often results in an early spike in temperatures 
along the coast. With offshore flow over the interior...highs will 
also be several degrees hotter than yesterday. Decided to boost 
temperatures a bit over the interior with widespread 90s from 
Seattle south...80s to low 90s mostly inland from the water north of 
Seattle...and 80s along the coast. This will likely be the warmest 
day along the coast and another hot day inland continuing the trend. 


There is little change in the upper level pattern through 
Friday with dry offshore flow continuing. Mesoscale models such as the 
NAM-12 indicate the thermally induced low will remain over western Washington 
but stay inland from the coast. Weak onshore flow will develop at 
the coast with highs much cooler in the upper 70s...but the interior 
should have another hot day with widespread 90s again from Seattle 
southward. 


Models indicate the ridge will begin to flatten Friday night 
into Saturday with just slight 500 mb height falls over the region. 
Model solutions vary quite a bit on the strength of the developing 
west-northwesterly onshore gradients. Regardless...the European model (ecmwf) usually resolves 
the surface pattern the best in these cases and it still maintains 
the heat low over western Washington from about the interior waters eastward. Given 
the upper height falls and increasing flow through the 
Strait...highs will remain quite warm but begin to trend lower. 
Low 90s will still be possible for interior areas far inland from 
the water but highs will cool more dramatically west of Puget Sound sound. 
Temperatures this season have frequently surprised to the 
upside...thus forecast highs are generally above most MOS guidance 
the next 3 days. 


A heat advisory remains in effect for the Seattle metropolitan corridor 
southward along I-5 to Oregon. Temperatures will be as much as 15-20 
degrees above average for some places through Saturday...especially 
inland from the water today and Friday. Record high temperatures 
will be possible some some interior locations. 


Long term...most models weaken the high pressure ridge Sunday and 
Monday. 500 mb heights continue to trend lower and each day will 
have increasing onshore gradients. Areas near the foothills and 
parts of the SW interior may still reach close to 90 on 
Sunday...but most spots will fall back into the 80s...with 70s along 
the coast...Strait...and north interior. A stronger onshore push is 
likely Sunday evening which should result in further cooling. By 
Tuesday...highs should be closer to average for this time of year as 
a marine air mass prevails. A trough off the coast will approach on 
Wednesday with a chance of showers...especially west of Puget Sound sound and 
across the north. Mercer 


&& 


Climate...Seattle is on the verge of setting the record for the all- 
time warmest month. This includes the federal building records which 
go back to the 1890s. The warmest month on record for Seattle is 
August 1967 with an average temperature of 71.1 degrees. Through the 
29th the average temperature for July 2015 is 70.7 degrees. Seattle 
needs to record an average temperature of at least 76.5 degrees the 
next two days to break the record. 


Seattle also has a chance to break the record for the warmest 
average monthly low temperature. The current record is 59.9 degrees 
set in August 2013. Through the 29th the average low temperature for 
July 2015 is 59.7 degrees. 


It will not be a record for the warmest average monthly high 
temperature. The record is 83.7 degrees set in August 1967. Through 
the 29th the average high temperature for July 2015 is 81.8 degrees. 
Even with a couple of hot days ahead...the average high temperature 
for the month will only increase .8 to 1 degree. July 2015 will end 
being the second warmest month on record in terms of average high 
temperature. 


Today will be the 10th day this year with a high of 90 degrees or 
more. This will break the record for the most number of 90 degree 
plus days in a year. The old record was 9 set in 1958. 


Today will be the 8th day this month with a high of 90 degrees or 
more. This will break the record for most 90 degree plus days in a 
month. The old record of 7 was set in July 1958. Felton 


&& 


Aviation...an upper ridge will remain over the region. Continued westerly 
flow aloft. Atmosphere dry and stable. VFR conditions are expected 
across all of the area with little or no clouds expected. There may 
be patchy IFR ceilings/visibilities on the coast early this morning. 


Ksea...clear skies. Winds will remain northerly. 


&& 


Marine...high pressure offshore with lower pressure east of the Cascades will 
result in onshore flow through Friday. Borderline Small Craft Advisory 
winds are expected in the central and eastern Strait this evening. 
Winds through the Strait should reach Small Craft Advisory speeds 
Friday evening. Onshore flow will strengthen Saturday and this will 
result in the possibility of gale force winds over parts of the 
Strait of Juan Delaware fuca on Saturday and Sunday evenings. The flow 
will strengthen further on Monday with gales likely over the central 
and eastern Strait of Juan Delaware fuca. 


&& 


Fire weather... 
previous discussion...a very dry air mass aloft is settling 
over western Washington through Friday night. 850-700 mb layer 
average relative humidity will be running as low 10 percent between 
now and then. Middle- level Haines index will be solid 5 with values 
reaching 6 at times over the central Cascades...indicating a dry and 
unstable middle-level air mass. Will easily reach criteria for the dry 
and unstable category of red flag warnings through Friday evening. 
As a result... a red flag warning will soon be in effect. It will be 
targeted to locations above 2000 feet elevation...which will stick 
up above the inhibiting effect of low-level subsidence inversions. 
With such a dry air mass...leftover fuel moisture from recent rains 
will quickly become a memory. Over the mountain zones...this kind 
of air mass supports active fire behavior and rapid growth on 
existing fires. Haner 


&& 


Sew watches/warnings/advisories... 
Washington...heat advisory in effect from noon Thursday until 9 PM Saturday 
for parts of the Puget Sound sound region and southwest interior. 


Red flag warning in effect until 10 PM PDT Friday for the 
north and central Cascades and parts of the Olympic 
Mountains. 


Pz...none.
