End: 2017-05-19T06:29:00.000Z
Location: Branson Mem Arpt to Taneyville, Missouri

From Branson Mem Arpt to Taneyville, this EF0 tornado ran 0.3 miles across Taney County on May 19, 2017, touching down at 1:28 AM CDT and reaching 75 yards wide. It killed nobody and injured 1, and did $10,000 of property damage.

The rating scale

Tracks are drawn in the color of the rating. The Enhanced Fujita scale rates the damage rather than measuring the wind: the speeds are what that damage is taken to imply.

EF065 to 85 mphthis tornado
Light damage. Surface peeled off some roofs, gutters and siding damaged, branches broken, shallow-rooted trees pushed over.
EF186 to 110 mph
Moderate damage. Roofs badly stripped, mobile homes overturned or badly damaged, exterior doors lost, windows broken.
EF2111 to 135 mph
Considerable damage. Roofs torn off well-built houses, frame homes shifted on their foundations, mobile homes destroyed, large trees snapped or uprooted, cars lifted off the ground.
EF3136 to 165 mph
Severe damage. Whole stories of well-built houses destroyed, large buildings badly damaged, trains overturned, trees debarked, heavy cars lifted and thrown.
EF4166 to 200 mph
Devastating damage. Well-built houses leveled, structures with weak foundations moved some distance, cars thrown and large missiles generated.
EF5over 200 mph
Incredible damage. Strong frame houses swept off their foundations, car-sized missiles thrown more than 100 meters, steel-reinforced concrete badly damaged, high-rise buildings deformed.
Unrated
The survey recorded a tornado but could not put a number on it, most often because it crossed open country and damaged nothing a rating can be read from.

The damage survey

7 damage points were recorded along this path by NWS SGF, in the Damage Assessment Toolkit the survey teams carry. The strongest indicator was rated EF1. The highest wind the damage implies is 99 mph.

Survey points are preliminary and are the raw material the published rating was built from. Source: NWS Damage Assessment Toolkit.

What the Weather Service recorded

Multiple rounds of severe thunderstorms over a two day period produced numerous weak tornadoes and wind damage reports across the Missouri Ozarks. Training of storms led to localized heavy rainfall and minor flooding reports.

A brief EF-0 tornado touched down in Branson. It damaged a hotel and the local outlet mall. There was one person with a head injury. Estimated maximum winds were up to 75 mph.

An EF-1 tornado tracked from Rockaway Beach to just northwest of Taneyville. Numerous trees were damaged and uprooted. Estimated maximum winds were up to 100 mph.

From NOAA NCEI's Storm Events Database, the narrative the local forecast office wrote for Storm Data.

The warnings

12 minutes of warning. NWS SGF issued a tornado warning for this county at 06:16 UTC, 12 minutes before the tornado touched down, in force until 07:00 UTC.

The county was under a tornado watch, issued at 04:06 UTC and running to 07:43 UTC.

Area Forecast Discussion
National Weather Service Springfield MO
1201 AM CDT Fri May 19 2017

.SHORT TERM...(This evening through Friday)
Issued at 250 PM CDT Thu May 18 2017

An upper level low is slowly pushing east across the Rockies
region this afternoon as an associated area of surface low
pressure is located across northwestern Texas. A warm front
extends from the surface low across southern Kansas into central
Missouri. A dry line extends south of the low across western
Oklahoma and Texas. Supercells are currently developing along the
dry line and will continue to develop along the dry line this
afternoon. Storms will also begin to develop farther to the north
across Kansas into northern Missouri this afternoon near the warm
front.

These storms will lift to the northeast and the cold pools should
congeal with line segments forming as they approach the area.
Will have to watch exactly where the lines develop to see
exactly what areas are affected. The storms that develop across
Kansas will likely lift northeast into northern Missouri north of
the area. We may need to watch any lines that form across
Oklahoma and Texas to track northeast into the area.

An unstable air mass will remain in place across the area this
evening and tonight so expect any line of storms that can develop
to likely maintain themselves as the track to the northeast across
the region. The storms will likely start to push into
southeastern Kansas and western Missouri between 8 and 10pm then
spread east into the overnight hours. Winds in excess of 60 mph
and hail to the size of quarters are expected with the strongest
storms. Late this evening into the overnight hours low level shear
will increase and if any line segments can surge to the northeast
there will be a meso vort potential with a tornado risk.

As the upper level energy lifts off the main low later tonight
additional storms will likely develop across Kansas and spread
east into the area late tonight into early Friday. The severe risk
with these storms will be lower but a few strong storms will still
be possible. These storms will linger into Friday before spreading
off to the northeast by Friday evening.

.LONG TERM...(Friday Night through Thursday)
Issued at 250 PM CDT Thu May 18 2017

The upper level low will spread into the Plains Friday
afternoon/evening with additional storms developing across
Oklahoma and Kansas again. These storms will once again form into
a line or line segments and spread into the area later Friday
evening into Friday night. These storms will spread across the
area into Saturday. Winds up to 70mph will be possible with these
storms and hail up to quarters with the strongest updraft. Low
level shear will once again increase Friday evening and night and
will lead to the potential of meso vorts and a tornado risk with
any lines that can surge to the northeast.

The storms will end from west to east on Saturday. Widespread 1
to 3" of rainfall with locally heavier amounts are expected from
tonight through Saturday with the heaviest occurring across
southeastern Kansas and Western Missouri. With multiple rounds for
rain expected we did issue a Flash Flood Watch for southeastern
Kansas and Western Missouri tonight into Saturday morning.

Cooler conditions will then occur Sunday into the first part of
next week and the region will be in a northwest flow pattern. May
have to watch for a couple waves riding the northwest flow and
creating shower and storm chances for the area Monday night into
Wednesday.

&&

.AVIATION...(For the 06Z TAFS through 06Z Friday night)
Issued at 1155 PM CDT Thu May 18 2017

A line of strong thunderstorms will move through the region
overnight and impact all area terminals. Where storms do occur,
visibilities and potentially ceilings will fall to MVFR. Heavy
rainfall, very gusty surface winds in excess of 60 mph will occur
as the strongest storms impact the regions Aerodromes. Hail may
also occur with these storms.

Showers and storms are expected to continue through much of the
day Friday with improving flight conditions and storms ending
during the evening hours.

This Hazardous Weather Outlook is for portions of the Missouri
Ozarks and extreme southeast Kansas.

.DAY ONE...Tonight.

Weather hazards expected...

  Limited Tornado risk.
  Elevated Hail risk.
  Elevated Thunderstorm wind damage risk.
  Elevated Flooding risk.
  Significant Lightning risk.

DISCUSSION...

  Thunderstorms will impact portions of extreme southeast Kansas
  and the Missouri Ozarks through the overnight hours. Winds up
  to 70 mph and hail up to the size of quarters will be possible
  with this activity. There will also be an isolated tornado
  risk with any line segments that can surge to the northeast
  generally along and west of Highway 65.

  Areas of heavy rain is likely tonight. Any training of storms
  may lead to localized flooding due to high water tables from
  previous excessive rainfall over the past couple of weeks.

.DAYS TWO THROUGH SEVEN...Friday through Wednesday.

  Thunderstorms are expected to linger into early Friday and
  dissipate by late morning.

  Additional strong to severe thunderstorms are expected Friday
  evening into the overnight hours. Damaging wind gusts and large
  hail will be the primary risks with these storms as they
  continue into Saturday.

  Storms should come to an end from Saturday night into Sunday
  morning with storm total rainfall area wide of 1 to 3 inches.
  The heaviest rainfall amounts and better flooding potential is
  expected to occur over southeast Kansas and west central
  Missouri.

  Additional thunderstorms will return Monday night into Tuesday
  as another storm system moves in from the northwest.

.SPOTTER INFORMATION STATEMENT...

  Spotter activation may be needed through the overnight hours.

What this means

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.
