Been busy today. Just saw the WWA in effect for here, Damn, going with 1-3 inches. More bullish than I expected.
Mount Holly AFD-
A complex weather pattern is evolving across the eastern two- thirds of the country. A surface low in the central Plains is ejecting eastward, attendant to a midlevel vort max shearing out in the downstream confluent flow across the Midwest and Northeast. Meanwhile, a strong vort max is digging southeast through the prairies of southern Canada, which will force the eastward acceleration of the southern-stream system. A zonally- oriented baroclinic zone extends to the southern Mid-Atlantic, with precipitation spreading into Virginia and North Carolina this afternoon. As the baroclinic zone lifts northward somewhat this evening, a predecessor perturbation will race through the Mid-Atlantic region. With ambient boundary-layer dry air (sufficiently cool given the overcast spreading northward into the southern/central CWA today), a thump of precipitation will spread into Delmarva this evening. Model soundings suggest a few hours of strong omega in the dendritic growth zone, so if the low levels can saturate, some decent snow rates (up to a half inch per hour) may occur. Combined with wet-bulbing effects, a quick one to two inches of snow may accumulate, as advertised via much of the hi-res guidance. Have issued a winter weather advisory for Delmarva for this threat from 7 pm to 4 am.
