Within the approximate 850-700mb warm conveyor, strong ascent is aiding banding of heavy precipitation across parts of southeast New England. Additionally, steep mid-level lapse rates (associated with the mid-level dry slot wrapping into southern New England) are maintaining very weak elevated buoyancy.

Therefore, embedded convective elements may still yield a few lightning strikes over southeast New England this evening. ..Picca.. 03/08/2018 Read more
