  1. Injuries and deaths are for the tornado’s whole path, which may extend beyond this area.
  2. Weak tornadoes were under-recorded before Doppler radar coverage became national in the early 1990s, so earlier decades read low. Ratings use the Fujita scale before February 2007 and the Enhanced Fujita scale after.

  1. A smoke day is a date on which a smoke plume traced by NOAA Hazard Mapping System analysts from satellite imagery covered this place's point (the county's population centre or the city centre). Counts here are of medium or heavy smoke. Since 2018 analysts have often drawn light smoke as one area over most of the continent, so light-smoke counts are not comparable from year to year. The plumes show smoke anywhere in the air above, not air quality at the ground, and smoke hidden by cloud is missed.

Zero is normal; -3 or lower is severe drought and -4 or lower extreme drought. It describes the long-term balance of moisture, not water supply or crop losses.

These thunderstorms remained nearly stationary through much of the night producing 12 to 14 inch rainfalls. This is in combination to the 6 to 8 inches of rain that had fallen in the days preceding the flood. The rain in Brown County fell directly into the catchments of the Jim Ned Creek, and Pecan Bayou, which empty into Lake Brownwood. Lake Brownwood crested on Sunday morning of the 7th, 7.7 feet over its spillway. Major flooding in Brownwood begins around 6 feet over the spillway. The flooded Pecan Bayou turned much of the Brownwood business district into a giant lake. Commerce Street…

    A wind gust of 87 MPH was measured by a Davis weather station before the anemometer broke. The survey team observed damage to several buildings and they saw numerous downed trees. An apartment wall collapsed and several mobile homes were severely damaged. The winds were part of a squall line that was moving through the area. A funnel cloud was sighted to the south of Brownwood shortly before the winds hit, and was likely associated with the tornado to the east of Brookesmith.
