<div>1. DISCUSSION AND FORECAST FOR NORTHEAST FORECAST AREA ZONES 630-638</div>
<div> </div>
<div style="padding-left: 36pt; ">Upper level trough moves through the region tonight and tomorrow keeping cool, northwesterly flow over the region. Trough will move by to the east Friday afternoon as an upper ridge approaches from off the coast. Air mass
slowly dries out but remains unstable. Expect mostly cloudy skies with a chance of a few light showers. Snow level will range from 2500 – 4000 ft. Good mixing and moderate NW’erly flow will make for excellent smoke dispersion.</div>
<div> </div>
<div> OUTLOOK (SATURDAY - MONDAY):</div>
<div> </div>
<div style="padding-left: 36pt; ">A period of spring like weather finally makes an appearance over the weekend and into early next week as an upper level ridge moves in on Saturday and Sunday. The next frontal system dives mainly to the south of the state
later Sunday and Monday. It appears the region will stay dry through the period with moisture staying to the south in California. Air mass will stabilize, especially during the night and morning, then destabilize during the afternoon. Wind flow weakens and
turns offshore. Smoke dispersion slowly worsens.</div>
