<div>1. DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623</div>
<div> </div>
<div style="padding-left: 36pt; ">A cool upper trough will remain over the region overnight tonight and drop slowly south-southeast during the day tomorrow. Impulses moving from north to south along the west side of this low will keep showers going throughout
the day. Afternoon snow levels will rise to around 2500 feet in the north and 3500 to 4000 feet in the south. Transport winds will be generally northwesterly and mixing heights will be favorable for good to excellent smoke dispersal conditions.</div>
<div> </div>
<div> OUTLOOK (WEDNESDAY - FRIDAY)</div>
<div style="padding-left: 36pt; "> </div>
<div style="padding-left: 36pt; ">Showers will end Wednesday with the approach of an upper level ridge from the west. Smoke dispersal conditions should remain good and transport winds will be northwest to north most areas. Thursday the upper ridge moves over
the area. Transport winds become light and variable Thursday and Friday and mixing heights lower for deteriorating smoke dispersal conditions. </div>
