During the early afternoon on Sunday, April 20, 2025 (Easter Sunday) a severe thunderstorm developed in Miller County, Missouri and moved northward through Cole County and into Callaway County. The thunderstorm produced one EF-2 tornado near New Bloomfield, MO. This occurred ahead of a line of severe thunderstorms that formed in southwest Missouri and extended northward as it moved east. The line moved into mid-Missouri during the late afternoon hours and marched into eastern Missouri. It produced 4 tornadoes in Missouri and damaging wind reports across the region.

A brief tornado tracked south to north just west of Highway MM in north-central Audrain County, destroying a couple of outbuildings and rolling two smaller grain bins. Debris was generally thrown northward and strewn widely, likely due to a downburst immediately following the tornado. The tornado was rated EF-1 with a path length of 0.32 miles and a maximum path width of 50 yards.

31 minutes of warning. NWS LSX issued a tornado warning for this county at 22:25 UTC, 31 minutes before the tornado touched down, in force until 23:04 UTC.

The county was under a tornado watch, issued at 18:47 UTC and running to 23:51 UTC.

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 Enhanced Risk, with a 0.10 chance of a tornado within 25 miles, in the hatched area where significant tornadoes were expected. The outlook in force was issued at 19:53 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 St Louis radar (KLSX), 118 km away, was scanning. The volume nearest the touchdown began at 22:55 UTC.

39 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.
