Survey Summary:

A line of severe thunderstorms moved east into southern MD Monday

evening June 22, 2026. This line of storms was the cause of a

widespread severe weather outbreak across portions of both VA and

MD. One of the storms developed rotation as it moved out of St. Marys

County and across the Patuxent River into Calvert County.

Once that storm moved into Calvert County, terminal doppler

weather radar at Joint Base Andrews (TADW) indicated an

intensifying rotation as it neared Battle Creek, moving quickly

east at 50 mph. A drone video captured the tornado developing, and

tornadic damage was first reported off Honey Cove Court on the

west shore of Battle Creek. Several large branches were snapped on

several trees, one fell onto a dock. An eyewitness on Shamrock Ct

on the east shore of Battle Creek saw the tornado crossing the

creek before they took shelter. More tree damage was reported

along Shamrock Court, as well as along Crane Road and Shannon Way.

An eyewitness off Crane Road passed along a video recording of

rotating and lofted leaf debris. After crossing Shannon Way, the

tornado lifted, although intermittent minor tree damage continued

in St. Leonard due to downburst winds after the rotation weakened.

Office thanks the Calvert County Office of Emergency Management

for their assistance. Additionally, thanks to the trained

spotters, media, and public that sent in videos of the tornado, as

well as damage reports.

Written by NWS LWX in the NWS Damage Assessment Toolkit. A survey is revised as better evidence arrives.

3 damage points were recorded along this path by NWS LWX, in the Damage Assessment Toolkit the survey teams carry. The strongest indicator was rated EF0. The highest wind the damage implies is 75 mph.

• Several large branches snapped down on several large trees. Some damage to the NE.
• Several large branches snapped on Several large trees along Crane Rd as well as Shannon Way.

Survey points are preliminary and are the raw material the published rating was built from. Source: NWS Damage Assessment Toolkit.

Lines of thunderstorms developing well out ahead of a cold front in a hot and unstable environment resulted in scattered instances of damaging wind gusts. A few destructive wind gusts were noted in north-central Virginia.

From NOAA NCEI's Storm Events Database, the narrative the local forecast office wrote for Storm Data.

No tornado warning for this county appears in the archive as in force at the moment the tornado touched down.

The county was under a severe thunderstorm watch, issued at 18:10 UTC and running to 00:53 UTC.

Every warning and watch covering the touchdown point that day, from the Iowa Environmental Mesonet's archive of National Weather Service products. Lead time is measured from the issue of the warning in force to the touchdown time in the database, both of which were recorded to the minute by different people.

The Storm Prediction Center had this point in a Slight Risk, with a 0.02 chance of a tornado within 25 miles. The outlook in force was issued at 19:57 UTC.

SPC's Day 1 convective outlook as it stood when the tornado began, read at the touchdown point. The same archive is on the radar archive.

The radiosonde launches on either side of the tornado, from the nearest station that was launching then, drawn and analyzed the way Storm Lab does: the same diagram, the same parcel and shear definitions SPC's mesoanalysis uses.

Ratings are the survey's, read off the damage rather than measured; the rating scale is above. A survey can be revised, so the rating, the path and the casualties can all still change.
