F0 tornado, York County, Nebraska, June 22, 2003

This F0 tornado ran 0.2 miles across York County on June 22, 2003, touching down at 8:30 PM CDT and reaching 30 yards wide. It killed nobody, and did $30,000 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 mphthis tornado

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

  2. F173 to 112 mph

    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.

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, with a 0.15 chance of a tornado within 25 miles, in the hatched area where significant tornadoes were expected. The outlook in force was issued at 00:25 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.

HAZARDOUS WEATHER OUTLOOK
NATIONAL WEATHER SERVICE HASTINGS NE
255 PM CDT SUN JUN 22 2003

THIS HAZARDOUS WEATHER OUTLOOK IS FOR SOUTH CENTRAL NEBRASKA AND
PARTS OF NORTH CENTRAL KANSAS.

.DAY ONE...THIS AFTERNOON AND TONIGHT

THERE IS A MODERATE RISK FOR SEVERE THUNDERSTORMS LATE THIS AFTERNOON
AND INTO THE EVENING OVER PARTS OF SOUTH CENTRAL NEBRASKA AND NORTH
CENTRAL KANSAS. IT APPEARS THE MOST LIKELY AREA FOR SEVERE STORMS
WILL BE MAINLY NORTH AND EAST OF A GOTHENBURG TO RED CLOUD TO MANKATO
KANSAS LINE. THIS WOULD INCLUDE THE TRI CITIES AREA.

THE ATMOSPHERE HAS BECOME MORE UNSTABLE THIS AFTERNOON AS MORNING
CLOUDS GAVE WAY TO INCREASED SUNSHINE. STRONG SOUTHERLY WINDS
CONTINUE TO TRANSPORT AMPLE LOW LEVEL MOISTURE INTO THE REGION. IN
ADDITION...A COLD FRONT THAT WAS LOCATED FROM JUST EAST OF AINSWORTH
TO NEAR GOTHENBURG AND THEN SOUTH THROUGH MCCOOK SHOULD PUSH SLOWLY
EASTWARD. OTHER BOUNDARIES THAT WERE PRODUCED FROM THUNDERSTORMS LAST
NIGHT AND THIS MORNING WILL ALSO HELP TO INITIATE THUNDERSTORM
DEVELOPMENT. ONE BOUNDARY WAS LOCATED NORTH OF FULLERTON AND ORD...
WHILE ANOTHER WAS JUST WEST OF YORK AND EXTENDED SOUTH TO CONCORDIA
KANSAS. IN ADDITION...WIND SHEAR PARAMETERS REMAIN FAVORABLE FOR
GENERATING SUPERCELL THUNDERSTORMS OVER THE REGION. THE COMBINATION
OF ALL THESE FACTORS POINT TO THUNDERSTORM DEVELOPMENT WITH SOME
STORMS PRODUCING LARGE HAIL...DAMAGING WINDS AND TORNADOES.

EMERGENCY MANAGERS SHOULD CONTINUE TO MONITOR THIS SITUATION
THROUGHOUT THE AFTERNOON.

.DAYS TWO THROUGH SEVEN...MONDAY THROUGH SATURDAY

EXTREMELY UNSTABLE CONDITIONS ARE EXPECTED TO REDEVELOP LATE MONDAY
AFTERNOON AND EVENING OVER PARTS OF SOUTH CENTRAL NEBRASKA...WITH
SEVERE THUNDERSTORMS POSSIBLE...MAINLY ALONG AND NORTH OF
INTERSTATE 80.  LARGE HAIL AND DAMAGING WIND ARE POSSIBLE...AS ARE
ISOLATED TORNADOES.

THUNDERSTORM CHANCES FOR PARTS OF THE AREA WILL CONTINUE THROUGH MID
WEEK WITH ADDITIONAL SEVERE WEATHER POSSIBLE BY TUESDAY AFTERNOON OR
EVENING.

.SPOTTER INFORMATION STATEMENT...

SPOTTER ACTIVATION WILL LIKELY BE NEEDED BY LATE THIS AFTERNOON INTO
THE EVENING.

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.
