Did it verify

Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this severe thunderstorm warning while it was in force. That is not proof nothing happened: reports are thin where few people live.

Cow counts a report within 15 km of the polygon while the warning was in force: a tornado for a tornado warning; hail of 1 inch or more, a gust of 58 mph or more or wind damage for a severe thunderstorm warning; a flash flood report for a flash flood warning.

The nearest sounding before it

...PRECIP CHANCES THE NEXT FEW DAYS OVER THE EAST THE CONCERN...

CURRENTLY...SURFACE BOUNDARY OVER THE PLAINS HASNT RETREATED
NORTHWARD MUCH TODAY...WITH EAST WINDS HOLDING SHALLOW MOIST LAYER
AGAINST THE MOUNTAINS. CLOUDS DEVELOPING OVER TELLER COUNTY...
DOWNWIND OF THE HAYMAN FIRE...WITH A FEW CUMULUS FORMING EAST OF THE
WET MOUNTAINS AND ALONG THE RATON MESA. FARTHER WEST...DRY W-SW
UPPER FLOW REARING ITS UGLY HEAD AGAIN...WITH HIGHER ELEVATION AWOS
SITES GUSTING OVER 40 KNOTS AT TIMES ALONG WITH RH VALUES IN THE
TEENS.

LAST NIGHT...HEAT/SMOKE/PARTICULATES FROM THE HAYMAN FIRE GENERATED
CONVECTION OVER TELLER COUNTY WHICH MOVED ALONG THE PALMER DIVIDE
AND TAPPED INTO THE MORE UNSTABLE AIR MASS FARTHER EAST...RESULTING
IN ISOLATED SEVERE STORMS ON THE PLAINS. OUTFLOWS FROM THIS
CONVECTION THEN INITIATED FURTHER ACTIVITY OVER EL PASO/TELLER
COUNTY...WHICH LINGERED PAST MIDNIGHT. SUSPECT CONVECTION WOULD HAVE
NEVER OCCURRED WITHOUT THE EXTRA LIFT PROVIDED BY THE FIRE...AS AIR
MASS OVER THE EAST WAS TOO CAPPED TO ALLOW THINGS TO DEVELOP.

TONIGHT...LATEST VISIBLE IMAGE SUGGESTS TSRA AGAIN A POSSIBILITY OVER
TELLER/EL PASO COUNTIES...SO WILL KEEP AT LEAST ISOLATED POPS GOING
FOR NOW. ELSEWHERE OVER THE EAST...CANT RULE OUT AN ISOLATED TSRA...
ESPECIALLY ALONG THE SRN EDGE OF CUMULUS FIELD IN PROWERS/KIOWA
COUNTY.

THURSDAY...COOL FRONT SURGES BACK SOUTHWARD ACROSS THE PLAINS AS
UPPER LOW FINALLY SHIFTS NORTHWARD INTO CANADA...ALLOWING SURFACE
HIGH PRESSURE TO MOVE SOUTHWARD INTO THE CENTRAL U.S. ENOUGH MOISTURE
AND UPSLOPE TO WARRANT LOW POPS ERN MOUNTAINS AND PLAINS...THOUGH
AIR MASS MAY BE TOO STABLE FOR MUCH IN THE WAY OF DEEP CONVECTION.
STILL DRY FARTHER WEST...THOUGH WINDS MIGHT DECREASE SLIGHTLY.
LEANED TOWARD WARMER FWC MAXES.

FRIDAY...MORE OF THE SAME WITH WEAK ERLY UPSLOPE AT THE SURFACE AND
NWRLY FLOW ALOFT. MIGHT SEE SLIGHTLY BETTER CAPES WITH A LITTLE
MORE SUN/HEATING...THOUGH AGAIN WONT GO ANY HIGHER THAN SLIGHT
CHANCES.

SATURDAY...SAME STORY THIRD VERSE SATURDAY...THOUGH AVN SUGGEST W-
NWRLY MID AND UPPER FLOW TO INCREASE BY EVENING...WHICH MAY SHOVE
BEST CONVERGENCE OUT ONTO THE PLAINS. STILL KEPT LOW POPS GOING OVER
THE ERN MTNS AND PLAINS. WENT A LITTLE ABOVE GUIDANCE FOR MAX
TEMPS.

EXTENDED...AVN HAS STG S/W TROUGH TOPPING THE RIDGE SATURDAY AND
DIVING SE SUNDAY...DRAGGING A NEW COLD FRONT ACROSS THE EAST.
CURRENT FCST HAS SLIGHT COOLING WITH LOW POPS...AND WILL
CONTINUE FOR NOW. RIDGE MOVES EASTWARD EARLY NEXT WEEK ACCORDING TO
