<div>1. DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623</div>
<div> </div>
<div style="padding-left: 36pt; ">An upper level disturbance dropping southward from British Columbia on Monday will develop into an upper level low over the Pacific Northwest on Tuesday. This will produce periods of rain throughout the day for most of the
area. The rain will taper off later in the day, but showers are likely through Wednesday. With the cooler air aloft the atmosphere will be rather unstable and mixing heights should be favorable for good smoke dispersal. Expect transport winds to be generally
from the southwest or south-southwest. </div>
<div style="padding-left: 36pt; "> </div>
<div> OUTLOOK (WEDNESDAY - FRIDAY):</div>
<div style="padding-left: 36pt; "> </div>
<div style="padding-left: 36pt; ">The upper low drifts slowly eastward across the state on Wednesday. Snow levels in the Cascades will be as low as about 3500 feet Wednesday morning. Showers will continue throughout the day. Mixing heights will remain high,
but winds will vary through the day. In the north expect easterly winds early, becoming northwest. In the south winds will start out south-southwest and shift to westerly. By Thursday the upper low will pass to the east allowing weak ridging to build over
the area. Weather should be dry but winds will again be quite variable; Northwest through west in the north, and northeast through north in the south. On Friday a Pacific weather system moves toward the state from the southwest. Rain will spread northward
during the afternoon and a wet weekend is in store. Once again Friday winds will vary with location: In the north generally easterly in the morning then becoming southwesterly, in the south southeasterly becoming northwest.</div>
<div style="padding-left: 36pt; "> </div>
<div style="padding-left: 36pt; ">Main message through the outlook period: Good dispersion but changing transport wind directions requiring close monitoring and coordination for locations near SSRA’s. </div>
