Kinetic energy increases late tonight, diffluence aloft,
elevated dewpoints and plenty column moisture, and eastward
progressing bands of low-level convergence, should lead to
convection crossing the area after midnight. SW winds near 50 kt
in the 2-3 kft layer, and moderate CAPE bears a watch. The main
axis of mean 0-3 km helicity will track along and west of I-95,
but a secondary axis will lift north adjacent to the rising
warm front, so there appears to be an isolated tornado risk
after midnight but before daylight, as well as a localized
straight-line wind hazard..
