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

Denver, CO (KDNR), launched 00:00Z, 6.1 hours before the alert went out and 159 km from the middle of its area. This is the routine balloon launch nearest before it, the air the forecaster had in hand, not a measurement taken for the alert.

...ISOLATED DRY THUNDERSTORMS AROUND THE CONTDVD THIS EVE...

CURRENTLY...WATER VAPOR IMAGERY AND RUC MODEL UPPER AIR ANALYSES
SHOWED THE NEXT CYCLONIC SHEAR AXIS FROM WRN CO INTO DESERT SW
MOVING SLOWLY E-NEWD.  AT THE SFC...IT APPEARS THE FRONTAL BOUNDARY
EXTENDS FROM THE SRN FOOTHILLS THRU EXTREME SERN CO WITH A MORE
PRONOUNCED BOUNDARY FROM THE PALMER DVD E-SEWD.  TEMPS ONLY IN THE
50S N OF THIS BOUNDARY...BUT ELEVATED SHRA/TSRA DEVELOPING IN E
CNTRL CO PER REGIONAL RADARS.  MUCH OF SERN CO IS IN-BETWEEN THE 2
AIR MASSES...BUT THE ATMOSPHERE IS QUITE MOIST/UNSTABLE ACROSS SERN
CO. CU/TCU ALREADY STARTING TO FORM AROUND THE SRN FOOTHILLS WITH SC
HOLDING TIGHT IN THE LOWER AR RVR VALLEY. RADAR IS SO FAR QUIET. OUT
AROUND THE CONTDVD...A DRIER AIR MASS CONTINUES WITH HAINES INDICES
OF 5/6. CU/TCU/CB STARTING TO FORM AROUND CONTDVD...BUT ONLY
ISOLATED AT THE MOMENT.

TNGT...BUSY DAY...SO LITTLE TIME FOR DISCUSSION. SEE SPC DAY 1
DISCUSSION FOR SEVERE THREAT. WILL GO WITH 50/60% POPS IN SERN CO FOR
TNGT AS ANY ISOLD-SCT SHRA/TSRA COULD EVOLVE INTO A MCS ACROSS ERN
CO/WRN KS IN RESPONSE TO THE APPROACH UPPER LEVEL SUPPORT. MID LEVEL
MOISTURE WILL CERTAINLY BE IN PLACE WITH SFC/PBL DEW POINTS 55-65F
AND H7-H5 SPECIFIC HUMIDITY VALUES OF 5.5-7.0 G/KG. OVERALL...
GEORGES K-INDICES SHOWING VALUES OF 35-41C AND FREEZING LEVEL HEIGHT
IS AROUND 10K-13K FT AGL WOULD SUPPORT HEAVY RAIN...ESPECIALLY IN
CELL TRAINING AND MERGER SITUATIONS. PLENTY OF INSTABILITY WITH
CAPE VALUES OF 3K-4K J/KG AND LIFTED INDICES OF -4C TO -9C ACROSS
SERN CO.  AROUND OUR CONTDVD AND SAN LUIS VALLEY...WILL BACK OFF
POPS TO 10%(ISOLATED) WITH SUCH DRY AIR AND HAINES VALUES AROUND 6.
THIS ALSO FITS BETTER WITH GJT. WOULD ONLY EXPECT LITTLE OR NO
RAIN...LOCAL WIND GUST AROUND 50 MPH...AND A FEW CLOUD TO GROUND
LIGHTNING STRIKES.

THU...PRETTY MUCH MORE OF THE SAME.  OLD FRONTAL BOUNDARY/MCS
OUTFLOW BOUNDARY SHOULD KEEP LOW LEVEL MOISTURE IN PLACE ALONG THE

CONTINUES TO BE IN A RELATIVELY DRY SLOT WITH THE POTENTIAL FOR
PRECIPITATION AROUND 10% AND HAINES VALUES OF 5/6. WILL DECREASE
POPS AND IT WILL MATCH BETTER WITH GJT. FOR THIS EVE AND THU
AFTN/EVE...THERE WILL BE THE POTENTIAL FOR DRY THUNDERSTORMS ACROSS

THIS HAZARDOUS WEATHER OUTLOOK IS FOR SOUTH CENTRAL AND SOUTHEAST
COLORADO.

.DAY ONE...TODAY AND TONIGHT.

SEVERAL SEVERE THUNDERSTORMS WILL BE POSSIBLE ACROSS ALL OF SOUTHEAST
COLORADO THIS AFTERNOON.  THE MAIN THREATS FROM THUNDERSTORMS WILL
BE LARGE HAIL UP TO 2 INCHES IN DIAMETER...LOCALLY HEAVY RAINFALL...
WIND GUSTS IN EXCESS OF 58 MPH...AND DANGEROUS LIGHTNING. AN ISOLATED
TORNADO WILL ALSO BE POSSIBLE.  SCATTERED THUNDERSTORMS ARE EXPECTED
TO BECOME MORE NUMEROUS OVERNIGHT AS THEY CONGEAL INTO A THUNDERSTORM
COMPLEX ACROSS SOUTHEAST COLORADO AND SOUTHERN KANSAS.

A COLD FRONT IS EXPECTED TO MOVE INTO SOUTHEAST COLORADO IN THE
AFTERNOON.  ALONG AND AHEAD OF THIS FRONT...RICH LOW LEVEL MOISTURE
WILL CONTINUE TO POOL ACROSS SOUTHEAST COLORADO.  WITH AFTERNOON
HEATING...THE ATMOSPHERE ACROSS THIS REGION IS EXPECTED TO BECOME
MODERATE TO STRONGLY UNSTABLE. THIS IN COMBINATION WITH AN
APPROACHING UPPER LEVEL DISTURBANCE...WILL LEAD TO THE DEVELOPMENT OF
SCATTERED THUNDERSTORMS AFTER 100 PM ALONG AND AHEAD OF THE COLD
FRONTAL BOUNDARY. SEVERAL OF THESE THUNDERSTORMS COULD BECOME SEVERE.
SUFFICIENT WIND SHEAR WILL BE PRESENT FOR THE DEVELOPMENT OF
SUPERCELL THUNDERSTORMS...WITH THE THREAT OF LARGE HAIL AND DAMAGING
WINDS AND AN ISOLATED TORNADO. THE GREATEST THREAT FOR SEVERE WEATHER
WILL BE LOCATED NORTHEAST OF A LINE FROM WALSENBURG TO KIM AFTER 100
PM. THUNDERSTORMS ARE EXPECTED TO CONTINUE OVERNIGHT ACROSS SOUTHEAST
COLORADO WITH A DECREASING TREND FROM NORTHWEST TO SOUTHEAST AS THE
THUNDERSTORM COMPLEX MOVES SOUTHEASTWARD INTO KANSAS.

ISOLATED TO SCATTERED SHOWERS THUNDERSTORMS WILL BE POSSIBLE
AFTER NOON ACROSS THE MOUNTAINS AND HIGH VALLEYS. DUE TO DRY AIR IN
THE LOW LEVELS OF THE ATMOSPHERE...THE MAIN THREATS FROM THESE
THUNDERSTORMS WILL BE GUSTY WINDS UP TO 45 MPH AND DANGEROUS CLOUD TO
GROUND LIGHTNING. DUE TO DRY FUELS ACROSS SOUTHWEST COLORADO...
ISOLATED LIGHTNING STRIKES COULD CAUSE WILD FIRE STARTS.
THUNDERSTORMS WILL DIMINISH AFTER MIDNIGHT.

.DAYS TWO THROUGH SEVEN...WEDNESDAY THROUGH MONDAY.

A WEATHER PATTERN QUITE FAVORABLE FOR AFTERNOON AND EVENING
THUNDERSTORM ACTIVITY WILL EXIST THROUGH THE REMAINDER OF THE WEEK
INTO EARLY NEXT WEEK. SHOWERS AND THUNDERSTORMS WILL BE POSSIBLE
NEARLY EVERY DAY. GIVEN ADEQUATE INSTABILITY AND WIND SHEAR...A FEW
OF THE STORMS DURING THE PERIOD WILL LIKELY BE SEVERE...CAPABLE OF
PRODUCING LARGE HAIL AND STRONG WINDS.

.SPOTTER INFORMATION STATEMENT...

WEATHER CONDITIONS THAT MEET REPORTING CRITERIA FOR SPOTTERS WILL BE
LIKELY AFTER 100 PM ACROSS SOUTHEAST COLORADO.
