DISCUSSION...A line of low-topped convection with little to no lightning is currently swinging east across southern New England, where a non-convective high wind event is ongoing with numerous measured gusts over 50 kt. Surface analysis shows relatively cool boundary layer temperatures over coastal areas as water temperatures are in the mid to upper 40s F. However, surface temperatures of 61-65 F exist from Boston southward due to longer wind trajectories over land. As such, a small pocket of higher theta-e exists in this area. Given the extreme wind fields just off the surface, this slightly warmer air could potentially augment surface gusts as the shallow convective line moves through. ..Jewell/Goss.. 12/18/2023 ...Please see www.spc.noaa.gov for graphic product...
