Continue reading for today's outlook from the National Weather Service's Storm Prediction Center. -------------------- National Severe Storm Outlook THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS THIS EVENING ACROSS PORTIONS OF THE NORTHERN MID ATLANTIC REGION INTO ADJACENT PORTIONS OF WESTERN NEW ENGLAND SUMMARY Thunderstorm activity spreading toward the northern Mid Atlantic urban corridor this evening could still pose a risk for damaging wind gusts and perhaps an isolated tornado or two, before weakening and spreading offshore. 01Z Update Low-level lapse rates are beginning to stabilize and the boundary-layer remains only modestly moist inland of coastal areas from New Jersey northward. However, the leading edge of a plume of boundary-layer moisture return characterized by upper 60s to near 70F surface dew points is still contributing to CAPE on the order of 1000 J/kg across parts of central and eastern Maryland into southeastern Pennsylvania, where temperatures remain near 80 F. With stronger mid/upper forcing for ascent still upstream, vigorous thunderstorm development may be maintained into and across much of eastern Pennsylvania and portions of the lower Hudson Valley through mid to late evening. Low-level hodographs across this region still appear conducive to at least some risk for a tornado, mainly in the more discrete stronger cells preceding the pre-frontal convective line. While the line has recently been weakening, some re-intensification still appears possible, which could be accompanied by increasing potential for strong to severe surface gusts, in the presence of 40-50 kt southwesterly deep-layer mean flow.
