<div>1. DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623</div>
<div> </div>
<div style="padding-left: 36pt; ">Warm front is approaching the region this afternoon and will increase clouds over mainly the north half of the state this afternoon and evening. Snow level will rise to 6000 – 7000 ft. Rain will likely start on the north
coast by this evening. This front will be similar to the one on Monday and Tuesday with the trough stalling off the coast for a day. Thus expect rain and wind over the northwest corner of the state tomorrow and mostly just clouds and windy conditions elsewhere.
Strong winds will mix out the stable air mass overnight and bring good smoke dispersion during the day.</div>
<div> </div>
<div> OUTLOOK (FRIDAY - SUNDAY)</div>
<div> </div>
<div style="padding-left: 36pt; ">Warm front moves by to the north by Friday with the cold front and trough approaching Friday morning. Rain will be on the increase while the winds start to slacken. Cold front moves through by Friday evening with cold air
following and lowering the snow level to near 3000 ft Friday night. Upper level trough moves through Friday night to Saturday morning. Another front and trough move in later Saturday with the trough passing through early Sunday with a ridge following closely
behind. Expect good mixing and smoke dispersion through the period.</div>
