<div>1. DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623</div>
<div> </div>
<div style="padding-left: 36pt; ">Rather strong cold front moves into the region this evening bringing a good dose of moisture and brisk wind. Air mass will remain mostly unstable tonight with good to excellent mixing and smoke dispersion tomorrow. Rain turns
to showers on Friday with continued blustery winds as the upper level trough moves in. Snow level will lower to 4000 ft in the north and 5000 ft in the south. </div>
<div> </div>
<div> OUTLOOK (SATURDAY - MONDAY)</div>
<div> </div>
<div style="padding-left: 36pt; ">Upper level trough remains over the region on Saturday with impulses of moisture keeping the area wet, and accumulating good amounts of snow in the mountains above 3500 – 4000 ft. Upper trough moves by to the east on Sunday
with a minor ridge building in. Showers will diminish. Air mass will begin stabilizing Sunday night under the ridge after another unstable day Sunday. Ridge will then move by to the east and yield to another front and trough moving in Monday afternoon.
Expect generally good mixing and dispersion through the period under this fall-like blustery rain pattern.</div>
