<div>1. DISCUSSION AND FORECAST FOR SOUTH CENTRAL OREGON ZONES 624 AND 625</div>
<div> </div>
<div> MONDAY</div>
<div style="padding-left: 36pt; "><font face="Consolas, monospace"> </font></div>
<div style="padding-left: 36pt; ">The upper ridge that brought sunshine to much of Oregon over the weekend moves east on Monday. Upper flow becomes southwesterly. Moisture will be limited but expect partly cloudy skies and there is a slight chance of evening
thunderstorms. Cooling aloft will keep afternoon mixing heights quite high for good smoke dispersal conditions. Transport winds will be generally north or northwesterly. </div>
<div style="padding-left: 36pt; "> </div>
<div> OUTLOOK (TUESDAY-THURSDAY)</div>
<div> </div>
<div style="padding-left: 36pt; ">An upper level low drops down the British Columbia coastline and across northwest Washington during the day Tuesday. This will increase the southwesterly flow aloft. Widely scattered afternoon showers are again likely. High
mixing heights will give good smoke dispersal conditions. The upper level low covers the entire Pacific Northwest by Wednesday, increasing southwesterly flow aloft. A few afternoon showers or thunderstorms is again a possibility. Fair to good smoke dispersal
conditions. Thursday will still see an upper level trough over the region, but more sunshine should drive afternoon mixing heights higher for good smoke dispersal conditions. </div>
