<div>1. DISCUSSION AND FORECAST FOR NORTHEAST FORECAST AREA ZONES 630-638</div>
<div> </div>
<div style="padding-left: 36pt; ">An upper level low sets up about 200 miles west of Waldport, Oregon giving south to southwest flow aloft. An upper short wave in this flow sill bring showers mainly to central Oregon with those showers moving northward during
the evening hours. </div>
<div style="text-indent: 36pt; "><font face="Consolas, monospace"> </font></div>
<div style="text-indent: 36pt; ">(OUTLOOK) THURSDAY – SATURDAY</div>
<div style="text-indent: 36pt; "> </div>
<div style="padding-left: 36pt; ">On Thursday the upper low backs off and moves west, farther off the coast. The upper short wave will rotate out of the state into Washington early in the morning leaving the region dry with a southerly flow aloft. Expect
good mixing heights and good burning conditions most areas. On Friday the upper low continues off the coast with another weak short wave moving northward across the region producing scattered showers. On Saturday a front develops offshore and moves to the
northern coast late in the afternoon. Elsewhere expect dry weather with strong southerly transport winds and mixing heights high enough for good smoke dispersal conditions. </div>
