The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Spokane, WA wrote its last area forecast discussion before the first event at Sep 4, 3:04 AM PST, 31 minutes earlier.
Area Forecast Discussion National Weather Service Spokane WA 404 AM PDT Sun Sep 4 2022 .SYNOPSIS... Sunday and Labor Day will be warm with mostly sunny skies. Afternoon temperatures will be mainly in the 80s. Temperatures will warm back into the 90s on Tuesday and Wednesday. The arrival of a cold front Thursday will bring the chance for mountain showers and temperatures cooling into the 80s. && .DISCUSSION... Sunday and Labor Day: A weather system brushing by far northwest Washington will result in increasing westerly flow aloft. A surface front will traverse the Cascades this afternoon, which will lead to breezy and gusty winds through the Cascade Gaps; namely Wenatchee and west-east oriented valleys south of there. The Okanogan Valley could see some breezy/gusty south winds as well with the pressure gradient tightening. Wind gusts on the order of 20 to 25 mph will be common in these locations and should be during the late afternoon/evening time period. Ahead of the trough passage, and well defined on water vapor satellite early this morning, a weak short- wave ridge will allow temperature today to warm about 5-6 degrees above Saturday's readings. Southerly winds will begin to increase as the trough rotates into Washington state today. This will be good news for air quality and smoke as it should help shift some smoke/haze north of our border and diffuse it a bit. Some improvement anyway. The latest HRRR smoke model has most of the integrated and near surface smoke clearing the Inland Northwest by late this afternoon. The exception could be the far southeast corner of Washington and adjacent counties in Idaho (Camas Prairie) which could be a little slower to improve overnight into Monday. The trough passage through far northern Washington will keep the jet oriented into southern British Columbia as well as most of the precipitation potential. The Cascade Crest could see some light showers with this wave moving through the evening hours. Temperatures will see a few degrees of cooling Labor Day (Monday) as the ridge is more flattened and lower heights shift over head. Temperatures should be much more "normal" for this time of year. Some breezes again in the Cascade gaps will be common early Monday with the exiting shortwave trough feature. /Dewey Tuesday through Saturday: Very strong high pressure will develop over the Great Basin. 500mb heights will approach the impressive benchmark of 6000 meters, rare but not impossible. This high pressure will amplify into the northwest, pushing the jet stream up into Canada. The computer models all see a weather system currently out at the dateline near the Aleutian Islands. They all bring it to near the southern BC coast, where it then has to deviate northeastward as it nears the massive high over the western US. The models then differ a bit on how this wave will move onshore, but they all agree that it will move through the Inland NW Wed/Thu. Temperatures will warm as the high amplifies for the first part of the week, and by Wednesday, temperatures are solidly in the 90s yet again, and may reach the triple digits in the L-C valley. Depending on the strength and timing of the wave for mid-week, Wednesday could be a potentially worrisome day. With hot temperatures and increasing winds aloft ahead of the wave, we could see a gusty afternoon with very low humidities, causing fire weather concerns. The actual model guidance isn't very windy, but the overall pattern suggests that Wednesday could be windier than expected. For the latter half of the week, a jet stream ridge moves onshore and phases with the Great Basin high. This will keep our forecast dry but not as hot into the weekend, with temperatures generally in the 80s. RJ AVIATION... 12Z TAFs: Clear skies and diurnally driven winds are expected at most area air fields today. The exception will be Wenatchee which will see increasing winds after 23z today and continuing through late tonight thanks to a tight pressure gradient across the Cascades. Elsewhere, Pullman may experience degraded visibility due to area wildfire smoke, briefly to MVFR at worst before 18z. /Dewey && .PRELIMINARY POINT TEMPS/POPS...
