<div> </div>
<div style="padding-left: 36pt; ">An upper level disturbance will move into northern California during the day and upper flow shifts from southwesterly to southerly. This will push more moisture into the Pacific Northwest. Daytime heating destabilized the
atmosphere and afternoon showers are likely with possible thunderstorms. Expect high mixing heights for good smoke dispersal conditions. </div>

<div> OUTLOOK (TUESDAY-THURSDAY) </div>

<div style="padding-left: 36pt; ">An upper level low in the Gulf of Alaska keeps southwesterly flow aloft over the region for Tuesday. There will be enough moisture for widely scattered showers. Smoke dispersal conditions should be good. Look for dry weather
on Wednesday until mid afternoon when moisture from a Pacific system crosses the Cascades and spreads east. </div>
