The National Weather Service confirmed Monday afternoon that an EF-2 tornado rolled through the Eastern Shore around 1:30 a.m. Monday morning. Along with the damage residents woke up to Monday morning, the National Weather Service confirmed one injury to a person “punctured by debris.”

Monday morning’s tornado, which touched down in Stevensville, Md., produced winds up to 125 mph, was the first EF-2 on the Eastern Shore since May 5, 2002.

The National Weather Service in Mount Holly, which monitors the Eastern Shore, described their damage assessment in a report Monday afternoon:

Several wood framed townhomes had the upper floors entirely lifted off along with the roof; several other homes had either roofs lifted off and tossed or received other damage. One business was destroyed. There was one injury to a person who was punctured by debris. In addition, there were trees and power lines down and some gas leaks were reported along with a structure fire to a home.

After late-night thunderstorms passed over the Beltway, they strengthened in Prince George’s and Anne Arundel counties. Residents there who may have just fallen asleep woke up to thunder, lightning and a severe thunderstorm warning. The circulation in that storm consolidated as it tracked over the Chesapeake, where it formed a waterspout just south of the Bay Bridge. The waterspout moved into the Bay City neighborhood of Kent Island at 1:29 a.m., according to the report. It lifted at 1:33 a.m., and was on the ground for approximately two miles.

About 1:30 a.m., the National Weather Service issued a tornado warning for Queen Anne’s and Kent counties.

Below is what we were seeing on radar as the storm passed through Stevensville, Md. On the left is regular reflectivity, which we use to see where the heaviest rain and hail is falling. On the right is wind speed and direction, which shows where the circulation is located. The pink and red colors indicate winds are blowing east; green indicates winds are blowing west.

The storm “was very intense with supercell-like characteristics,” said Jeff Halverson, the Capital Weather Gang’s severe weather expert, “namely, it contained an unusually strong ‘velocity couplet’ [above] … suggestive of a rotating updraft.”

He also said that such a storm rotation signature “is rarely observed after midnight in our region.”

In terms of the atmospheric setup that led to the storm, Halverson says he doesn’t see anything stand out that would favor rotating thunderstorms. “However,” he said, “when tornadoes develop close to or along the Bay, we often think of the heated land/cooler water interface creating a type of ‘microfront,'” which can promote spin in the atmosphere.

WJLA had a crew at the location early Monday and shared some devastating photos of the damage this storm caused. Multiple homes fell victim to the storm and dozens of trees were downed.

There have been 11 confirmed tornadoes in Queen Anne’s County since the modern record began in 1950. Almost all of them were rated “weak” or below EF/F2. The most recent confirmed tornado in the county was during the June 1, 2012, tornado outbreak in the region.

June and July tend to be peak tornado months for Maryland, which largely coincides with the general thunderstorm peak in the region.
