<div> </div>
<div style="padding-left: 36pt; ">The day begins with the region covered by the northern portion of an upper trough centered over central California. This will move to the east during the day and weather will remain dry. There will be a generally northwest

<div> OUTLOOK (THURSDAY-SATURDAY)</div>
<div> </div>
<div style="padding-left: 36pt; ">On Thursday a generally westerly flow aloft will develop. Weather will be dry and mixing heights should top 5000 feet. Transport winds will be generally southwest becoming more westerly during the day. By Friday a deep upper
low in the Gulf of Alaska builds a moderate upper ridge over the Pacific Northwest. Maximum mixing heights will remain high. The upper low moves closer on Saturday and flow aloft veers to more southerly. However, moisture stays well east of the state for
more pleasant, dry weather.</div>
