• Marine Thunderstorm Winds in North Atlantic Coastal Waters, February 25, 20171 death · 1.25 in hail · 22 eventsA potent cold front passed through the waters on the 25th. Southerly winds ahead of the boundary ushered in unusually warm and humid conditions for this time of year which led to some instability.
• Marine Thunderstorm Winds in North Atlantic Coastal Waters, April 26, 201965 kt wind · 38 eventsAn upper level trough east of the Mississippi River on the morning of April 26th deepened and closed off over the eastern Great Lakes by the morning of April 27th.
• Marine Thunderstorm Winds in North Atlantic Coastal Waters, June 1, 20120.75 in hail · 27 eventsLow pressure tracked through the Ohio Valley and into the Great Lakes. The warm front associated with this system passed through the waters during the first.
• Marine Thunderstorm Winds in North Atlantic Coastal Waters, June 29, 20191.75 in hail · 27 eventsHeat and humidity through the day on June 29th led to a moderately unstable air mass by the afternoon. A weak pressure trough developed and heights began to fall by the evening as an upper level ridge broke down.
• Marine Thunderstorm Winds in North Atlantic Coastal Waters, July 1, 201751 kt wind · 26 eventsA cold front moved into the area triggering showers and thunderstorms. Hot and humid air ahead of the boundary caused an unstable air mass, which led to gusty winds with some thunderstorms.
• Marine Thunderstorm Winds in North Atlantic Coastal Waters, May 25, 201750 kt wind · 24 eventsLow pressure and an associated cold front moved across the Mid-Atlantic region during the day on May 25th. Warm and humid conditions led to showers and thunderstorms. Some thunderstorms produced gusty winds and large hail.
• Marine Thunderstorm Winds in North Atlantic Coastal Waters, July 27, 20181.25 in hail · 24 eventsA cold front passed through the area on the 27th. Ahead of the boundary, a southerly flow led to plenty of moisture an unstable atmosphere. A potent upper-level low caused stronger winds aloft as well.
• Marine Thunderstorm Winds in North Atlantic Coastal Waters, June 2, 200956 kt wind · 23 eventsA pressure trough combined with warm and humid conditions to trigger showers and thunderstorms during the afternoon and evening hours of June 2nd.
• Marine Thunderstorm Winds in North Atlantic Coastal Waters, June 2, 20191 in hail · 23 eventsA cold front approached the region during the day of June 2nd, and that combined with broadly falling heights and increasing instability and wind shear, led to the development of scattered strong to locally severe thunderstorms during the afternoon and evening hours.
• Marine Thunderstorm Winds in North Atlantic Coastal Waters, June 12, 201161 kt wind · 20 eventsA cold front combined with moderate instability to trigger showers and thunderstorms on the twelfth. Stronger winds aloft due to an upper-level low over New England caused thunderstorms to become well organized. Thunderstorms were able to produce gusty winds over the waters.
• Marine Thunderstorm Winds in North Atlantic Coastal Waters, June 14, 202158 kt wind · 19 eventsSeveral clusters of strong to severe thunderstorms produced high winds over the Chesapeake Bay and tidal Potomac River.
• Marine Thunderstorm Winds in North Atlantic Coastal Waters, June 9, 200950 kt wind · 18 eventsA cold front approached the waters on the 9th. Ahead of the front, warm and humid air led to unstable conditions. The instability combined with the boundary and an upper-level disturbance to trigger showers and thunderstorms on the afternoon and evening hours of the 9th.
• Marine Thunderstorm Winds and Waterspout in North Atlantic Coastal Waters, July 1, 200953 kt wind · 16 eventsA potent cold front passed through the waters on the first. Ahead of the front, plenty of moisture lead to unstable conditions. The instability combined with the forcing from the front to trigger showers and thunderstorms. Thunderstorms produced gusty winds and large hail.
• Marine Thunderstorm Winds in North Atlantic Coastal Waters, June 24, 2010$10,000 · 1.75 in hail · 15 eventsA Cold front and strong 500hPa trough moved across the Tri-State, triggering severe thunderstorms across the waters around Long Island.
• Marine Thunderstorm Winds in North Atlantic Coastal Waters, June 9 to 10, 201156 kt wind · 15 eventsPlenty of moisture continued to rotate around high pressure over the southeastern Conus. Hot conditions combined with the moisture to cause moderate amounts of instability to develop.
• Marine Thunderstorm Winds in North Atlantic Coastal Waters, August 2, 20081.75 in hail · 14 eventsA cold front passing through the waters combined with an unstable atmosphere to trigger showers and thunderstorms. Some thunderstorms were severe, producing gusty winds and large hail.
• Marine Thunderstorm Winds in North Atlantic Coastal Waters, April 21, 202059 kt wind · 14 eventsA cold front and pre-frontal trough, in association with a mid level disturbance brought strong to severe thunderstorms to the coastal waters.
• Marine Thunderstorm Winds in North Atlantic Coastal Waters, April 15, 202455 kt wind · 14 eventsSeveral hail-producing thunderstorms affected the tidal waterways of the Mid-Atlantic with large hail and gale-force wind gusts.
• Marine Thunderstorm Winds in North Atlantic Coastal Waters, August 14, 20081 in hail · 13 eventsAn upper-level low produced an unstable atmosphere, triggering showers and thunderstorms. Some of the thunderstorms produced gusty winds over the Chesapeake Bay.
• Marine Thunderstorm Winds in North Atlantic Coastal Waters, May 2, 20162.25 in hail · 13 eventsA cold front moved through the Mid-Atlantic region, with showers and thunderstorms developing ahead and along the frontal boundary. Many thunderstorms became severe with large hail and damaging winds.
• Marine Thunderstorm Winds in North Atlantic Coastal Waters, September 7, 20230.75 in hail · 13 eventsNumerous showers and thunderstorms developed along a lee pressure trough after several days of late season heat. Several of these storms produced strong winds and hail over the tidal Potomac River and Chesapeake Bay.
• Marine Thunderstorm Winds in North Atlantic Coastal Waters, June 22, 201052 kt wind · 12 eventsThe subtropical ridge was to our south while the subtropical jet remained just to our north. An upper-level disturbance in the jet stream passed through on the 22nd. Warm and humid air was in place due to a west-southwest flow around the ridge.
• Marine Thunderstorm Winds in North Atlantic Coastal Waters, August 27, 20200.75 in hail · 12 eventsAn upper level disturbance in close proximity to a departing warm front triggered severe thunderstorms across the coastal waters.
• Marine Thunderstorm Winds in North Atlantic Coastal Waters, July 19 to 20, 20161 in hail · 11 eventsA boundary stalled over the area. Warm and humid conditions led to an unstable atmosphere while an upper-level trough passed through the area. The forcing from the boundary front combined with the instability to trigger thunderstorms.
• Marine Thunderstorm Winds in North Atlantic Coastal Waters, April 21, 20171 in hail · 11 eventsA cold front moved through the area.
