<div>1. DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623</div>
<div> </div>
<div style="padding-left: 36pt; ">A strong Pacific weather system will move into the region today. A warm front is spreading rain into northwestern Oregon this morning. A cold front will follow later today for more rain and blustery conditions. Winds will
initially be from the south but shift to westerly with the passage of the cold front. Mixing heights will be high for good smoke dispersal conditions, but rainfall in the northern portion of the region will hamper any burning efforts.</div>
