0518 PM CDT Sat Apr 01 2023

Areas affected...Eastern Connecticut...Massachusetts...Rhode
Island...and southern New Hampshire

Concerning...Severe potential...Watch unlikely 

Valid 012218Z - 012315Z

Probability of Watch Issuance...20 percent

SUMMARY...Localized damaging wind threat may persist. A downstream
Severe Thunderstorm Watch is unlikely.

DISCUSSION...A line of storms currently moving across New York and
Pennsylvania has shown signs of weakening over the last hour. These
storms are moving into a more favorable environment across the East
Coast, where daytime heating has allowed for SBCAPE around 500 J/kg.
Mid-level cooling will continue to allow further destabilization
over the next couple of hours as the trough approaches from the
west. VAD profiles from Albany (KENX) show deep layer shear around
25-30 kts. As storms move into this environment slight
intensification will be possible, along with additional development
ahead of the main line. Given the wind profiles, a marginal damaging
wind risk is possible. A Severe Thunderstorm Watch is unlikely.
