<div>1. DISCUSSION AND FORECAST FOR NORTHEAST FORECAST AREA ZONES 630-638</div>
<div> </div>
<div style="padding-left: 36pt; ">Upper level ridge will weaken over the next couple of days as an upper low approaches from the southwest and a trough drops down from the north. Southerly flow aloft will continue the thundershower threat over the region but
mainly to the south. Air mass will remain stable and smoke dispersion mostly poor due to little wind movement. Otherwise expect mostly fair skies.</div>

<div> OUTLOOK (MONDAY - WEDNESDAY):</div>
<div> </div>
<div style="padding-left: 36pt; ">Upper level trough moves in closer on Monday and Tuesday. However, expect little change in the weather other than slightly cooler temperatures. Isolated afternoon to evening thundershowers are still possible. Expect little
change to the air mass with stable mornings and unstable afternoons due to heating. Wind flow will remain fairly light favoring NW to NE flow. Smoke dispersion will remain poor to fair.</div>
