9/8/2020 7:00 AM 0.00 0.0 M M M Corvallis smoky, ash falling and visibility about 5 miles at 7am - visibility less than one mile when the smoke arrived last evening about 6pm
9/9/2020 7:00 AM 0.00 0.0 M M M Smoke still shrouds the region. Winds are about 1/3 the strength of yesterday which should slow fire growth. Smoke in my area has cut visibility to 2 miles or less, but the only ash falling seems to be coming from trees and structures, hardly any new. This has been an unprecedented outbreak; I have friends and family evacuating from up and down the west side of the Cascades, and many small towns have been heavily damaged or wiped off the map.
9/10/2020 7:00 AM 0.00 0.0 M M M Winds have died down here, visibility still one mile or less but again, no ash falling.
9/11/2020 7:00 AM 0.00 0.0 M M M Temps much colder than expected this morning, 46F at 7am, which means the air is still relatively dry. smoke a bit lighter and no ash falling.
9/12/2020 7:00 AM 0.00 0.0 M M M Still stagnant air, thick smoke over area. Lack of wind allowing fire crews to start to get handle on fire lines. Over 1 million acres burned in less than 6 days.
9/13/2020 7:00 AM 0.00 0.0 M M M True smog. Only 48 at 7am, visibility <.2 miles.
9/14/2020 7:00 AM 0.00 0.0 M M M Smoke thinning, mostly fog now. Hope the worst is over and that we get into a damp pattern that will end the fire season for good!
9/15/2020 7:00 AM 0.00 0.0 M M M smoke has thinned, more marine air working into the valley.
9/16/2020 7:00 AM 0.00 0.0 M M M combination of fog and smoke lowered visibility to 200 yards at obs time. Corvallis is relatively fortunate - areas east and north of my site have much worse air quality.
9/17/2020 7:00 AM 0.00 0.0 M M M The ubiquitous fog/smoke mix, but the air quality had improved this morning at obs. Overall visibility was under a quarter mile tho.
9/18/2020 7:00 AM 0.41 M M M M Thunderstorms started about 6:30 pm and trained over site til at least 1:30 am. Frequent lightning, relatively few ground strikes and relatively low precipitation indicates high- based storms that did not anchor to the boundary layer. Air quality now only moderately unhealthy, best since a week ago monday evening
9/19/2020 7:00 AM 0.69 M M M M More thunderstorms with lightning caused power problems latter part of morning. But heavy showers much of the day. Dense fog this am but air quality is very good now.
