Day 1 Convective Outlook
NWS Storm Prediction Center Norman OK
0654 AM CST Fri Dec 19 2025
Valid 191300Z - 201200Z
...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS THE
MID-ATLANTIC/NORTHEAST STATES...
...SUMMARY...
Isolated damaging winds may accompany convection across the
Mid-Atlantic/Northeast today.
...North Carolina and Mid-Atlantic/Northeast States...
A prominent upper-level trough centered over the Great Lakes/Ohio
Valley will continue to take on a negative tilt as it quickly
transitions east-northeastward toward New England the Canadian
Maritimes tonight. A very strong deep-layer wind field (80-110 kt at
500 mb) is attendant to this trough, with these strong winds aloft
partially overlapping a modestly moist/minimally unstable warm
sector along the I-95 corridor/East Coast ahead of an
eastward-advancing cold front. A strongly forced semi-organized
low-topped convective line, with little or no lightning flashes, is
ongoing around sunrise across northeast North Carolina and southeast
Virginia, and this may further develop north-northeastward across
additional portions of the Mid-Atlantic region this morning. Even
with minimal buoyancy, some stronger/locally severe wind gusts could
occur this morning, and possibly through early afternoon across
parts of the near-coastal Northeast.
