From the record
What the reports say
Written by National Weather Service staff at the time of the event · public domain
Rainfall and rapid melting of low elevation snowpack on top of frozen and saturated soil led to widespread flooding. Many roads around Jerome were damaged and closed due to flood waters. Widespread flooding of agricultural lands occurred.
A tree branch with a width estimated to be 1.5 – 2 feet in diameter fell onto a parked car, causing significant damage to a parked car. Winds are estimated to be 65 MPH, given the size of the branch that fell while also taking into consideration that the branch appeared to be unhealthy in the image.
KMVT in Twin Falls relayed a video sent by a civilian of an EF0 tornado moving northwest to southeast along a gust front from a thunderstorm northeast of Jerome. The tornado began approximately 712 MDT and ended at 722 MDT. It was about 150 feet wide and moved through agricultural fields and no damage was reported. It is possible that the rotating column of air was a surface based gustnado since it was not clear if the updraft was connected to the parent thunderstorm. However, the rotating column had considerable height, strength and longevity.
