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.

What the Weather Service recorded

Severe thunderstorms produced large hail, from quarter to golfball size, across parts of Larimer, Morgan, Phillips and Morgan Counties. One tornado touched down briefly in an open field. In Douglas and Elbert Counties, lightning sparked three fires in the vicinities of Franktown and Elizabeth in the span of ten minutes.

A tornado touched down briefly in an open field; no damage was observed.

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

The warnings

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 Slight Risk. The outlook in force was issued at 19:50 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.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE DENVER/BOULDER CO
316 PM MDT SUN JUN 22 2014

.SHORT TERM...(THIS EVENING THROUGH MONDAY)
ISSUED AT 315 PM MDT SUN JUN 22 2014

SOME CONVECTION HAS DEVELOPED OVER THE FRONT RANGE EARLY THIS
AFTERNOON WITH THE STRONGER ACTIVITY OVER DOUGLAS COUNTY. STORMS
WILL CONTINUE TO EXPAND AND SHIFT EAST OVER THE PLAINS THROUGH
LATE AFTERNOON AND EVENING. EXPECT STORMS TO BECOME
STRONGER...SOME SEVERE AS THEY MOVE INTO MORE MOISTURE RICH
ENVIRONMENT FURTHER EAST ON THE PLAINS. OVER THE FRONT
RANGE...LATEST ACARS SOUNDINGS NEAR DENVER INDICATE SURFACE BASED
CAPES AROUND 1000J/KG WITH STILL A BIT OF CIN TO OVERCOME. HOWEVER
CLOUDS FROM STORMS WILL CONTINUE TO SLOW HEATING AND OVERALL STORM
STRENGTH WILL BE ON THE WEAKER SIDE.

FOR MONDAY...THE FLOW ALOFT BECOMES MORE WEST AND NORTHWEST WITH
WEAK HIGH PRESSURE OVER THE GREAT BASIN. THERE WILL BE A BIT
STRONGER AND DEEPER LOW LEVEL FLOW WHILE MID LEVEL FLOW IS
STRONGER. OVERALL...SEVERE WEATHER THREAT LOOKS BETTER ON MONDAY
AFTERNOON WITH BETTER SHEAR PROFILE AND HIGHER INSTABILITY. PW
VALUES ALSO APPROACH AN INCH SO ALSO POTENTIAL FOR HEAVY RAIN AND
MORE OF A FLASH FLOOD THREAT. MAIN CHANGE TO ZONES WILL BE TO
INCREASE POPS A BIT OVER THE FRONT RANGE.

.LONG TERM...(MONDAY NIGHT THROUGH SUNDAY)
ISSUED AT 315 PM MDT SUN JUN 22 2014

NOT MUCH TO SINK ONE'S TEETH INTO DURING THE PERIOD. WEST TO
NORTHWEST FLOW ALOFT WITH WEAK UPSLOPE LOW LEVEL FLOW WILL KEEP
SOME MOISTURE BANKED UP AGAINST THE MOUNTAINS THROUGH MIDWEEK WITH
CONDITIONS DRYING OUT TOWARD THE END OF THE WEEK AND INTO THE
WEEKEND. THESE CONDITIONS WILL BE SUFFICIENT TO KEEP THE THREAT OF
AFTERNOON/EVENING CONVECTION GOING MONDAY EVENING THROUGH THURSDAY
WITH LESSER CHANCES THEREAFTER. INSTABILITY/SHEAR WILL LIKELY BE
ENOUGH TO KEEP A LOW RISK OF SEVERE STORMS DURING THAT PERIOD AS
WELL. TEMPERATURES WILL BE AROUND NORMAL THROUGH MOST OF THE
PERIOD EXCEPT IN THE OUTER PERIODS WHEN WARMER THAN NORMAL
CONDITIONS SHOULD OCCUR.

&&

.AVIATION...(FOR THE TAFS THROUGH 00Z MONDAY LATE AFTERNOON)
ISSUED AT 315 PM MDT SUN JUN 22 2014

EXPECT MAINLY WEAK CONVECTION OVER TERMINALS AS STRONGER STORMS
REMAIN SOUTH THROUGH DOUGLAS COUNTY. THE TEMPO THUNDER MAY BE TOO
MUCH BUT WILL REEVALUATE OVER NEXT FEW HOURS. COULD SEE A DENVER
CYCLONE SET UP ON MONDAY MORNING AND STILL A POTENTIAL FOR SOME
STRATUS EARLY IN THE AM. BETTER COVERAGE OF STORMS FOR MONDAY
AFTERNOON WITH DEEPER MOISTURE...UPSLOPE FLOW AND DENVER CYCLONE
IN PLACE.

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.
