NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Seattle Washington 
300 PM PDT Sat Jul 4 2015 


Synopsis...the warm spell will continue through the middle of next 
week. Cooler weather will arrive late next week as an upper trough 
nears the area and onshore flow increases. 


&& 


Short term...much above normal temperatures will continue. The coast will 
also heat up on Sunday as the surface thermal trough expands westward 
over the coastal waters. As the flow turns back to light 
onshore Monday or Tuesday some coastal fog and low clouds should 
develop and the coast should cool down. Inland areas will see the 
warm stretch continue. 


Long term...the warmth continue through at least Wednesday and 
low level onshore flow is likely to remain fairly weak. A cooling 
trend should start Thursday and Friday as an upper trough nears the 
area and stronger low level onshore flow develops. The 12z GFS is 
slow and weak and splits an approaching upper trough compared 
to earlier runs...and the southern portion of this trough simply 
replaces an old cut off low that has been off northern calif for awhile 
now. As that old calif cut off low kicks inland some 
showers should go into eastern Oregon and maybe eastern Washington late in the week 
but western Washington is likely to remain dry. Marine layer cloudiness is 
fairly likely for western Washington late in the week with the thermal trough 
having shifted well inland and western Washington temperatures should be closer to 
average. 


&& 


Aviation...strong high pressure remains offshore while an upper 
level low spins over Alberta and Saskatchewan. The flow aloft over 
western Washington is northwest. The air mass is dry. High pressure and offshore flow 
will keep skies clear on sun for VFR conditions. 33 


Ksea...VFR conditions. Light north winds at the surface. 33 


&& 


Marine...offshore flow will develop tonight and sun as a thermal 
trough of low pressure forms along the coast. Expect northerly winds of 
10 to 20 knots over the interior waters on sun. The flow will flip back 
to onshore Monday and Tuesday as low pressure shifts inland. 33 


&& 


Fire weather...the good news for fireworks-related activities is 
that breezes in the major population centers will be light. That is 
about all the good news there is. NE gradients will be picking up 
overnight tonight and peaking around sunrise on Sunday. The 
Bellingham-Williams Lake b.C. Gradient is already -6.8 mb and 
strengthening. Before midnight...this will initiate the development 
of gusty NE winds in the north Cascades...with Marblemount likely 
being dry and windy overnight (that is normally a calm and humid 
location at night). Overnight...NE winds will kick in over western 
Whatcom County...the San Juan Islands...and the northwest olympic 
peninsula. This will usher in a warm and dry Continental air mass 
with some places experiencing decreasing relative humidity 
overnight. The most critical conditions will occur late Sunday 
morning...during a period before winds die down but after relative humidity has 
dropped for the day. The NE winds will usher in hot temperatures all 
the way to the coast...with Forks expecting a high of 92 degrees on 
Sunday. 


Most of the Puget Sound sound lowlands will see relative humidity drop 
into the 18-30 percent range on Sunday afternoon. That range is 
about as dry as we get around here. Meanwhile...the Puget Sound sound 
lowlands along and west of I-5...especially the Kitsap 
peninsula...should have north-NE winds of 10-15 miles per hour early in the 
afternoon. Winds of that modest magnitude with such low humidity and 
such dry fuels could really push grass fires along quickly... 
especially where wind and slope align. A red flag warning is being 
issued to handle the combination of wind and low relative humidity 
on Sunday. 


Lastly...the middle-level Haines index will be in the 5-6 range on 
Sunday afternoon. This indicates a dry and unstable air mass in the 
850-700 mb layer. Fires burning at elevations above about 2000 feet 
under such conditions can become Rowdy and plume-dominated. 


With such hot and dry weather this weekend...along with fuels that 
are unprecedentedly dry for so early in fire season...please be 
careful with flammable materials. The conditions this Fourth of July 
are far beyond the level of fire danger that has been experienced in 
the lifetime of many who will be playing with fireworks this 
weekend. By the same token...firefighters responding to wildland 
fires should expect unusually volatile conditions and fight fire 
having provided for safety first.Haner

Sew watches/warnings/advisories... 
Washington...a heat advisory is in effect until midnight Sunday night for 
parts of the Puget Sound sound region. 


Pz...none.
