Near Term - Through Today
As of 230am Thu...Surface low now just off the southern coast will cont to move ENE and deepen today as impressive short wave crosses. Fcst trends look good as widespread rain conts and appears is beginning to change to snow NW tier. The change to snow will cont to spread SE thru daybreak as colder air pushes S on backside of the low. NW counties will have longest duration on snow and expect 2 to 3 inches this region with locally higher amounts. The snowfall totals will be lower as move SE given shorter duration of snow and temps remaining at or above freezing. Cont Winter Wx Advisory for all but southern coast and central/southern OBX. Will be close to warning criteria for the most NW tier but will hold off for now given warmer ground temps limiting impacts...however there most likely will be poor travel conditions for the morning commute.

Models show precipitation intensity rapidly weakening after 12Z as mostly light snow tapers off and end thru late morn from W to E. Despite increasing sunshine from mid day on will be cold espcly N where expected snow cover will keep highs in the 30s with lower 40s S.

Models continue to show a secondary low (Miller-B) to form off the Mid-Atlantic coast leading to more rain and possible a rain/snow mix on the back-side of the low as it lifts away with lingering showers on Tuesday. High pressure is forecast to build into the region by midweek. Expect highs in the upper 40s to mid 50s Sunday/Monday, then temperatures drop back into the 40s.
