A strong cold front crossed central New York State during the late afternoon and early evening hours of Friday April 19th. This front was accompanied by a squall line which produced locally damaging wind including a confirmed EF1 Tornado in Chenango and Delaware counties. Most areas saw brief heavy rain and wind gusts to 50 mph with a few locations seeing intense straight line winds between 80 and 110 mph.

A tornado touched down about 4 miles South Southeast of Bainbridge in Chenango County and tracked northeast about 3.2 miles, and then ended about 3 miles South of Sidney in Delaware County.||The tornado touched down between Interstate 88 and highway 206, on East Afton Road, where 2 power poles were snapped and a car was destroyed by a large tree branch. Another vehicle was also damaged. Several trees were snapped or uprooted. A barn had minor roof damage. The tornado continued northeast and crossed highway 206, where a farm equipment building and a mobile home were heavily damaged, and a storage trailer was destroyed. Other nearby homes had minor damage, and a carport was lifted and moved 75 feet. Farther down its path, the tornado intensified to a high end EF1 strength while traveling in the vicinity of Houck Drive. In this area, it uprooted or snapped many 1 to 2 foot diameter trees along its path, both hardwoods, maples, and softwoods, pines, with the largest more than 3 feet wide. It also caused structural damage to a single family residence and garage, while transporting a significant amount of debris a hundred yards or more. The tornado then crossed into Delaware county, downing several more trees on some properties along Highway 8 before dissipating.

No tornado warning for this county appears in the archive as in force at the moment the tornado touched down. One was issued for the county at another hour that day.

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, with a 0.02 chance of a tornado within 25 miles. The outlook in force was issued at 19:10 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 Binghamton radar (KBGM), 47 km away, was scanning. The volume nearest the touchdown began at 23:53 UTC.

6 more were confirmed in the United States that day.

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.
