DISCUSSION...Widely scattered shower and thunderstorm activity is ongoing across portions of the Northern Adirondacks in New York to Kennebec Valley in Maine. Through much of the morning and early afternoon, this area has been under mid-level cloud cover which has reduced daytime heating. As a result of this and ongoing showery activity, very marginal instability is in place. This is observed from the 18z ALB and GYX soundings. Though instability remains weak, deep layer shear around 40-45 kts may support a few stronger updrafts capable of strong to severe wind and marginally severe hail. Given the spatially limited nature of this risk, a watch is unlikely at this time. ..Thornton/Mosier.. 06/14/2026 ...Please see www.spc.noaa.gov for graphic product...
