A complex frontal system was affecting the mid-Atlantic on June 13. That evening, a west to east oriented warm frontal boundary was located roughly along the borders of Pennsylvania with Maryland and Delaware, and into adjacent areas of New Jersey. While the environment north of this boundary was cool and stable, conditions along and south of the front were more favorable for convection. A line of strong to severe thunderstorms tracked along this boundary, producing areas of damaging wind. In addition, along the northern edge of this line which tracked along the boundary itself, a localized area of enhanced shear led to multiple tornado touchdowns.

A tornado touched down in Elk Neck State Park in southwestern |Cecil County, MD around 7:02 PM on Thursday, June 13. It is |possible this tornado formed offshore as a waterspout which then |came onshore. Hundreds of trees were snapped or uprooted in Elk |Neck State Park in a pattern consistent with tornadic winds. A few|outbuildings also sustained minor damage. The tornado tracked |east-northeastwards towards Hollywood Beach. Only minor damage was|observed in this area, and the tornado is estimated to have |lifted at 7:10 PM. No injuries were reported as a result of this |tornado.

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.

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 General Thunderstorms Risk. The outlook in force was issued at 01:00 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.

The Dover AFB radar (KDOX), 86 km away, was scanning. The volume nearest the touchdown began at 03:00 UTC.

Ratings are the survey's, read off the damage rather than measured; the rating scale is above. Tornado counts rise through the record as reporting improved, so a year in the 1950s is not comparable with one today except for the strongest tornadoes, which were always noticed.
