<div> </div>
<div> WEDNESDAY</div>
<div style="padding-left: 36pt; "><font face="Consolas, monospace"> </font></div>
<div style="padding-left: 36pt; ">Cool weather will continue. A broad upper trough remains over the eastern Pacific and the Pacific Northwest on Wednesday. Most areas will see partly cloudy skies. Temperatures will be 3 to 7 degrees below average. Mixing
heights should climb to above 5000 feet throughout the region for good smoke dispersal conditions. </div>
<div style="padding-left: 36pt; "> </div>
<div> OUTLOOK (THURSDAY-SATURDAY)</div>
<div> </div>
<div style="padding-left: 36pt; ">A progressive disturbance moving across the Pacific Ocean deepens the trough over the area on Thursday. This supports a weak Pacific front that will move onshore late in the day. This will bring some light rain, mainly to
northern sections overnight Thursday and Friday. Maximum afternoon mixing heights should be above 5000 feet throughout the outlook period. Thursday’s partly cloudy skies will turn mostly sunny for Friday and Saturday. </div>
