<div>1. DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623</div>
<div style="padding-left: 36pt; "> </div>
<div style="padding-left: 36pt; ">The upper ridge over the Pacific Northwest that brought sunshine and warm weather to the region over the weekend will slowly move east. A trough in the Gulf of Alaska will strengthen and move toward Washington during the day.
Low level flow will go onshore and temperatures should be down a couple of degrees, and humidities will be up. Maximum mixing heights will climb to the 4-5000 foot range for good smoke dispersal conditions during the afternoon hours. </div>
<div style="padding-left: 36pt; "> </div>
<div> OUTLOOK (TUESDAY - THURSDAY):</div>
<div style="padding-left: 36pt; "> </div>
<div style="padding-left: 36pt; ">The trough in the Gulf of Alaska becomes an upper level low by Tuesday and tracks across southern British Columbia. Light rain from a weak Pacific cold front will move in early. Rain will be light with greatest amounts in
the north but some rain reaching as far south as southwestern Oregon. Tuesday mixing heights should provide for excellent smoke dispersal conditions during the afternoon. By Wednesday the upper trough tracks east and weak high pressure develops aloft. Expect
onshore flow, north to northwest transport winds and fair go good smoke dispersal conditions. A very weak upper trough develops that could touch off some mountain showers Thursday evening. Thursday transport winds will be northerly to northwesterly. </div>
