On May 18, a dryline clashed with a very unstable atmosphere to produce a long lived supercell, spawning several tornadoes, large hail and damaging thunderstorm wind reports.  On May 19, a southward moving front triggered numerous severe storms as it clashed with a very unstable airmass, resulting in reports of large hail, damaging winds and tornadoes.  A few of these tornadoes damaged some homes in northern Brown County on May 18.

This tornado also blew out large overhead garage doors.  The twister removed shingles from other residences and mostly destroyed small sheds.

Location: MAY
Tornado F-scale: EF1
Property damage: 0.00K
Crop damage: 0.00K
Reported by: NWS Storm Survey

A National Weather Storm Survey team found evidence of an EF1 tornado with wind speeds of about 107 mph, which began about 3 miles southeast of May, Texas in Hogg Mountain.  It moved southeast, then northeast and then turned back to the northwest and west.  Because it was nearly stationary, the tornado appeared to rotate with the parent mesocyclone.  The tornado uprooted many trees, snapped many tree trunks and branches of large Oak trees.  The tornado tore off a roof of a mobile home, destroyed a chicken coop, damaged outdoor furniture, ripped off sheet metal from a barn and tossed it for over 100 yards.  As the tornado continued to move west across County Road 478, it became about a half mile wide as it uprooted large Oak trees and snapped some tree trunks.  Eyewitness accounts and a photograph indicated this tornado had multiple vortices.
