<div>1. DISCUSSION AND FORECAST FOR NORTHEAST FORECAST AREA ZONES 630-638</div>
<div> </div>
<div style="padding-left: 36pt; ">Upper level ridge has built over the state today but is getting flattened somewhat by an approaching storm system. The warm front will ride over the top of the ridge this afternoon and evening providing some increasing clouds
and a chance of some light rain to the very northern part of the region tonight. The cold front will then ride through Friday afternoon and evening bringing increasing moisture later in the day and evening. Air mass is quite stable under the ridge and will
remain so until the cold front can bring cooler air aloft tomorrow afternoon. Smoke dispersion will be poor overnight then improves through the day as SW’erly flow increases on Friday.</div>
<div> </div>
<div> OUTLOOK (SATURDAY - MONDAY):</div>
<div> </div>
<div style="padding-left: 36pt; ">Upper level ridge will rebuild over the state Saturday following Friday’s front. Air mass stabilizes again. Ridge will continue over the region into Sunday before another front moves in during the afternoon and evening.
Expect another round of moisture late Sunday turning to showers on Monday. Snow level appears it will lower to near 5000 ft on Monday. Cooler air aloft will destabilize the air mass again on Monday. Expect poor to fair smoke dispersion Saturday and most
of Sunday then improving dispersion Sunday evening through Monday.</div>
