F1 tornado, Hubbell, Nebraska, June 13, 2001

This F1 tornado ran 3.0 miles across Thayer County on June 13, 2001, touching down at 9:05 PM CDT and reaching 150 yards wide. It killed nobody, and did $500,000 of property damage.

The rating scale

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

  1. F040 to 72 mph

    Light damage. Surface peeled off some roofs, gutters and siding damaged, branches broken, shallow-rooted trees pushed over.

  2. F173 to 112 mphthis tornado

    Moderate damage. Roofs badly stripped, mobile homes overturned or badly damaged, exterior doors lost, windows broken.

  3. F2113 to 157 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.

  4. F3158 to 206 mph

    Severe damage. Whole stories of well-built houses destroyed, large buildings badly damaged, trains overturned, trees debarked, heavy cars lifted and thrown.

  5. F4207 to 260 mph

    Devastating damage. Well-built houses leveled, structures with weak foundations moved some distance, cars thrown and large missiles generated.

  6. F5261 to 318 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.

  7. 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.

What the Weather Service recorded

A wild night of weather struck south-central Nebraska with high winds, hail and tornadoes. Of the five tornadoes confirmed, the most damaging one occurred southeast of Hubbell. One farmstead sustained around one-half million dollars in damage, including losing several outbuildings, grain bins, and an exterior wall on the home. The other tornadoes were quite brief, but one did manage to produce minor damage on a farm in eastern Furnas county.Another area of widespread destruction occurred with straight-line winds in extreme southern Clay and northern Nuckolls counties. Winds estimated at 90 mph tore through grain bins, outbuildings, and trees. Major damage was had at a turkey farm near Lawrence. The damage extended east along State Highway 4 across northern Nuckolls county to the tune of over one million dollars. There were dozens of other reports of large hail across south-central Nebraska, which caused significant crop damage in some locations.

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 forecast that day

The Storm Prediction Center had this point in a Moderate Risk. The outlook in force was issued at 01:05 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.

FRONT APPEARS TO HAVE FINALLY STALLED ACROSS CENTRAL CWFA...
BASICALLY ALONG A LINE FROM PALMER...TO KGRI...JUNIATA...AND
THEN TO BLOOMINGTON.

THE CONCERN IS CONVECTION TONIGHT...WHERE AND WHEN. FRONT WILL
HOLD STEADY TONIGHT...AND BE FOCUS FOR CONVECTION. BELIEVE AREAS
JUST TO NORTHEAST OF CWFA MAY SEE THINGS FIRE FIRST. BACK BUILDING
POSSIBLE...WITH CAPPING LIMITING SOUTHERN CWFA DEVELOP. ONCE SURFACE
LOW STARTS CHURNING IN SOUTHWEST KANSAS AREA IN RESPONSE TO UPPER
WAVE MOVING...AND LOW LEVEL STRONG LOW LEVEL JET KICKS IN...MUCH OF
CWFA WILL ERUPT INTO WIDESPREAD STORMS FOR THE OVERNIGHT. SEVERE
STORMS POSSIBLE...BUT TORNADO THREAT SEEMS TO BE DURING THE EVENING
HOURS...IF STORMS GET GOING THEN. RECENT HOT AND DRY TREND PRECLUDES
ANY ISSUANCE OF FFA FOR REGION.

LATEST MESOETA NOW MOVES UPPER LOW JUST A TOUCH FURTHER NORTH
ON THURSDAY...BUT AT ABOUT THE SAME SPEED. SOUTHERN CWFA WILL
BE IN DRY SLOT...AND COULD WARM NICELY WITH STRONG WEST FLOW.
WILL DROP OZF TEMPS JUST A BIT BUT AT LEAST AT GUIDANCE LEVELS
THERE. NORTHERN AREAS IN CLOUDS BEFORE BREAKING OUT...AND COOLER
TEMPERATURE ZONE. 60S LIKELY NORTHWEST ZONES. STILL A CHANCE
FOR SHOWERS/STORMS AND BELIEVE SEVERE THREAT WILL BE JUST TO
OUR NORTHEAST. WILL BE MAKING MINOR ADJUSTMENTS TO OZF POPS
THURSDAY AND THURSDAY NIGHT.

WARM...WEST FLOW FRIDAY SHOULD LEAD TO MILD TEMPERATURES UNDER
SUNSHINE.

THE AREA REMAINS UNDER A MODERATE RISK OF SEVERE WEATHER TONIGHT. BUT
WE ARE LOOKING AT TWO DIFFERENT WEATHER SYSTEMS THAT MAY GIVE US
SEVERE WEATHER.

THE FIRST AREA LOOKS HAVE THUNDERSTORMS POSSIBLE THIS EVENING EAST
OF HIGHWAY 281.  THIS AREA HAS DEW POINTS NEAR 70 DEGREES AND
TEMPERATURES IN THE UPPER 80S TO LOWER 90S.  WITH SUNSET A FEW MORE
HOURS AWAY...THUNDERSTORM DEVELOPMENT MAY OCCUR IN THIS AREA.  THE
PRIMARY THREAT THIS EVENING WILL BE PRIMARILY LARGE HAIL...BUT
TORNADOS CAN NOT BE RULED OUT.

THE NEXT AREA IS ALONG A COLD FRONT THAT HAS BECOME NEARLY
STATIONARY ACROSS THE REGION.  LATE THIS AFTERNOON...THE FRONT WAS
FROM NEAR FULLERTON TO GRAND ISLAND NEBRASKA TO PHILLIPSBURG
KANSAS.  AN AREA OF LOW PRESSURE IS GAINING STRENGTH IN SOUTHEAST
COLORADO AND WILL SLOWLY WORK ITS WAY INTO THE REGION TONIGHT.  AS
IT DOES...ADDITIONAL THUNDERSTORMS WILL DEVELOP ALONG THE FRONT.
AGAIN THE PRIMARY THREAT WILL BE FROM LARGE HAIL...BUT STRONG WINDS
AND AN ISOLATED TORNADO MAY STILL OCCUR.  THE BEST TIME FOR THE
SEVERE WEATHER IN THIS AREA WILL BE FROM 8 PM UNTIL 2 AM.

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.
