Within broadly cyclonic flow over the central/eastern CONUS, a
mid-level shortwave trough will rotate northeastward over New
England and the Canadian Maritimes today. A related coastal surface
low near southern New England is expected to develop northward into
ME by this evening. Even though instability will remain very weak,
isolated lightning flashes will remain possible for at least a few
more hours across parts of coastal New England in the low-level warm
advection regime of the cyclone. Dry and/or stable conditions and
minimal thunderstorm potential are forecast today for the rest of
the CONUS.
