<div>1. DISCUSSION AND FORECAST FOR THE WESTERN OREGON AREA FORECAST ZONES 601-623</div>
<div style="padding-left: 36pt; "> </div>
<div style="padding-left: 36pt; ">The main jet stream and storm track remain aimed at the Pacific Northwest on Wednesday. A surge of moisture from the west-southwest will reach the coastline early and spread across the region for periods of rain throughout
the day. Heaviest amounts will be during the morning hours. Transport winds will be generally southerly early then more southwesterly during the day. Mixing heights will remain high for favorable smoke dispersal conditions. </div>
<div style="padding-left: 36pt; "> </div>
<div> OUTLOOK (THURSDAY-SATURDAY):</div>
<div style="padding-left: 36pt; "> </div>
<div style="padding-left: 36pt; ">Surface high pressure off the California coast builds northward slowly on Thursday. Expect showers during the day, most numerous in northern sections. Mixing heights remain high and winds Thursday will be westerly in the
north and westerly turning to northwesterly in the south. By Friday the surface high noses into the Pacific Northwest for dry weather. A thermal trough develops in California and transport winds develop a northerly component. While weak ridging aloft develops
Friday and Saturday there will still be a fairly strong west-to-east flow aloft with minor imbedded impulses. At this point it looks like dry weather for Saturday, however. Mixing heights Friday and Saturday will lower somewhat but still be high enough during
the afternoons for fair to good smoke dispersal. </div>
