<div>1. DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623</div>
<div> </div>
<div style="padding-left: 36pt; ">Upper level ridge is flattening today and will open the door for a trough and cold front to drop down from the north. Cooler air will move in tomorrow afternoon and start destabilizing the air mass. Clouds will increase on
Friday but moisture will likely be very light to non-existent. Wind flow turns onshore from the northwest. Expect improving smoke dispersion through the day.</div>
<div> </div>
<div> OUTLOOK (SATURDAY - MONDAY)</div>
<div> </div>
<div style="padding-left: 36pt; ">Cold front and trough will drop to the south on Saturday bringing cooler but mainly dry air to the region. Air mass will continue to destabilize but still remain somewhat stable. Wind flow turns offshore. Another trough
and more arctic-like air mass will drop southward on Sunday bringing very chilly and unstable conditions. Again, moisture will be limited but some snow flurries or snow showers down to the valley floors are possible. Arctic northerly to easterly flow will
continue into Monday. Expect mostly good smoke dispersion through the period.</div>
