Thunderstorms associated with marginally severe wind gusts will be possible today from near the coast of New Jersey into southern New England. ...Coastal New Jersey/Southern New England... A strong upper-level system over the Great Lakes will move toward the central Appalachians today. Ahead of the system, a lead shortwave trough and an associated deepening surface low will move northward across the Northeast. A cold front near the Mid-Atlantic coast will move eastward into the near-coastal waters with a somewhat moist airmass located head of the front extending northward across southern New England. A few thunderstorms will be possible ahead of the front within this weak instability. An impressive 80 to 100 knot low-level jet will move northward across New England today. Storms that develop across southern New England could have an isolated wind-damage threat, as the stronger convection potentially helps to mix winds toward the surface. However, due to very weak instability, any threat is expected to remain marginal this morning and afternoon. ..Broyles/Thompson.. 12/18/2023 Read more View the full article Quote Link to comment Share on other sites More sharing options...
