<div>SMOKE MANAGEMENT FORECAST AND INSTRUCTIONS</div>

<div>1. DISCUSSION AND FORECAST FOR NORTHEAST FORECAST AREA ZONES 630-638</div>
<div> </div>
<div style="padding-left: 36pt; ">An upper ridge builds over the region. Mixing heights should remain high enough to provide fair smoke dispersal conditions. Weather will be dry and as a surface high builds over Montana transport winds will shift from southwesterly
early to southeasterly later in the day. </div>
<div style="padding-left: 36pt; "> </div>
<div style="padding-left: 36pt; ">OUTLOOK (FRIDAY-SUNDAY)</div>
<div style="padding-left: 36pt; "> </div>
<div style="padding-left: 36pt; ">Friday the surface high moves east and transport winds go southerly. Dry weather continues most of Saturday, but a weak front will bring rain to the area late in the day and overnight. Sunday will see a return to dry weather
but flat surface gradients mean light and variable winds making burning near sensitive areas problematic. </div>
