Latest disco on the severe threat from Mount Holly-
Deeper convection is forecast to develop to our west near a pre- frontal trough. The model forecast soundings indicate some discrete cells out that way should quickly consolidate into a convective line as it shifts eastward. An examination of model point forecast soundings indicate ample instability developing along with rather steep low-level lapse rates, and the mid level lapse are on the steeper side as well. The shear profiles are somewhat on the weaker side, however model soundings show some initial backed low-level flow with around 30 knots of shear. This would be enough when combined with strong forcing for ascent arriving for the risk for severe thunderstorms. Storms should organize into a line as it approaches our region with damaging winds and some hail the main threats. Given the backed near surface flow ahead of the line, cannot rule out some rotation within the eastward advancing squall line (QLCS) especially across Delmarva. CAM guidance shows convection quickly becoming linear, with even some hinting at strong outflow winds. Given the steep low-level lapse rates, downdraft instability (DCAPE) should be on the high side, which will enhance convective winds down to the surface especially associated with any forward surges in the line. With increased confidence in linear thunderstorm segments capable of producing damaging winds forming, the Storm Prediction Center now has much of our area south of the I-78 corridor in an Enhanced risk (level 3 of 5) for severe thunderstorms on Monday.
