NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Spokane Washington 
528 PM PDT Sat Aug 1 2015 


Synopsis.... 
expect a very hot weekend with afternoon temperatures in the mid 
90s to near 105. The ongoing drought combined with high heat and 
low humidity will raise concerns for wildfires the next several 
days. A cold front will bring temperatures back closer to average 
on Tuesday. Temperatures Wednesday through Friday will likely be 
at or below average. 


&& 


Discussion... 


Tonight and sunday: no changes to the fcst outside of increasing 
the areal coverage of smoke near the Cascades. Visibilities will 
likely remain obscured to less than one mile for certainly the 
immediate Lake Chelan area from the Wolverine fire. Low temps were 
warmed a bit also in these smoke-filled valleys based on low temps 
this morning.Bz 


Sunday night through wednesday: models are back in pretty good 
agreement of the large scale synoptic pattern through the first 
part of the work week. They are showing a wave move up from the 
south Sunday night through Monday. With this wave will be an 
increase in moisture and some very weak instability. Have added 
some sprinkles and thunderstorms to the forecast. Expect the area 
of sprinkles and thunderstorms to move up into the central 
Cascades early Monday morning and then spread north and east 
through the day and out of the area by Tuesday morning. With the 
additional cloud cover Sunday night and Monday night have 
increased temperatures several degrees to about 6-10 degrees above 
average for this time of the year. Tuesday and Wednesday we 
transition into a more west or northwesterly flow as an upper 
level low pressure system moves into central British Columbia. The 
track of this low is indicative of breezy winds in the Cascades, 
Columbia Basin and into the Palouse and Spokane/cda areas (about 
10-20 mph). The best chance of showers or thunderstorms will 
reside across the mountains. Daytime temperatures will finally 
drop to around average for Tuesday and maybe even below average 
for Wednesday. /Nisbet 


Wednesday night through saturday: expect relatively cool 
temperatures and a few opportunities for showers mainly around 
the mountains. Model agreement regarding the precise evolution of 
the pattern degrades with a lack of solid consistency. Loose 
agreement suggests an upper trough will continue to migrate across 
the Pacific northwest early this period. This is followed by brief 
shortwave ridging before another trough approaches. Additionally 
the low spinning off the California coast moves inland and potentially by 
southeast Washington and southern Idaho late next week. In short, 
shower/T-storm chances will linger around the Cascades and 
northern mountains Thursday and return here and toward The Blues 
through central Panhandle Saturday with approach of the next 
trough from the west and possible wave approaching from the south. 
Temperatures will be near to slightly below normal early this 
period, warming back closer to an above normal by late in the 
period. /J. Cote'

Aviation... 
00z tafs: a large plume of elevated smoke will continue to track 
towards Grand Coulee, Spokane, and Coeur D'Alene areas tonight 
but prevailing surface visibilities should remain VFR...although a 
fire near Sprague could track smoke up towards kgeg/ksff/kcoe. As 
the inversions sets in...lower level smoke will increase around 
Chelan, with the bluesky model keeping this smoke east of keat 
again...but impacting kmwh overnight into Sunday morning. 
Confidence is not high concerning timing of MVFR visibility as 
kmwh...so went with a compromise between timing of bluesky model 
and persistance. Some improvement is expected Sunday afternoon at 
kmwh as surface winds switch from north-northwest to SW. Jw
