Wind damage and a brief tornado are possible. DISCUSSION...Surface heating has been greater in New Hampshire and western Maine. Portions of northern Maine are beginning now beginning to heat as low-level cloud cover erodes and the warm front lifts into Quebec. Upstream convection has not deepened very quickly, particularly in northeast New York and Vermont. The more discrete activity in southeast New York into Connecticut/Massachusetts has shown marginally more intense/deep updrafts. Even with less than ideal thermodynamics, low-level lapse rates have steepened where temperatures have risen into the 80s F and stronger mid-level ascent continues to approach the Northeast. The strongest storms will be capable damaging wind gusts. Low-level shear is also sufficient for a brief tornado. ...Wendt/Hart.. 06/19/2025 ....Please see https://urldefense.com/v3/__http://www.spc.noaa.gov__;!!DZ3fj= g!6n2ZqwuDcS2WOcabff35z2DQUUHzXQbsE8lfpMkZyYDKO6BaY1c31vtAgYAPpaV5CSMzhUo0B= NO4Zjzk5BXiWKKq8Co$ for graphic product...
