<div>1. DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623</div>
<div> </div>
<div style="padding-left: 36pt; ">Upper level low is moving through the region early this morning bringing continued shower activity and low snow levels. Air mass will be mostly unstable today with minor stability over the southern and eastern parts of the
region during the morning hours. Weak ridging moves in this afternoon and evening before the next frontal system and trough move in tomorrow. Expect generally diminishing showers activity through the day. Despite the minor ridging, plenty of cool air aloft
should make for good mixing and dispersion. </div>
