MD 0434 CONCERNING SEVERE POTENTIAL…WATCH UNLIKELY FOR EASTERN CONNECTICUT…MASSACHUSETTS…RHODE ISLAND…AND SOUTHERN NEW HAMPSHIRE
Mesoscale Discussion 0434 NWS Storm Prediction Center Norman OK 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. ..Thornton/Hart.. 04/01/2023 ...Please see www.spc.noaa.gov for graphic product...
