<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; ">Upper level ridge continues to build over the state but is being overrun by clouds from a warm front off the coast. This front will slowly move into the region Thursday morning bringing increasing clouds and a chance of some
light moisture. Air mass will remain stable as warming air aloft continues to enhance the lower level temperature inversion. Increasing wind flow from the south should provide fair smoke dispersion.</div>
<div> </div>
<div> OUTLOOK (FRIDAY - SUNDAY):</div>
<div> </div>
<div style="padding-left: 36pt; ">Upper ridge with warm front clouds and light moisture continues through Friday before the ridge flattens and gives way to a cold front on Saturday. Moisture amounts with the cold front will also be light. Air mass will destabilize
Saturday for a brief period before stabilizing again Saturday night and Sunday as the upper ridge rebuilds again. Wind flow will increase ahead of the front on Friday and remain brisk through much of Saturday providing decent smoke dispersion. Winds then
decrease later Saturday and become quite light on Sunday, making for considerably poorer smoke dispersion.</div>
<div> </div>
