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.

What forecasters said that day
The local office's own words before this severe thunderstorm warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Denver/Boulder, CO wrote its last area forecast discussion before this severe thunderstorm warning went out at Apr 19, 2:45 PM MDT, 2 hours earlier.
Area forecast discussion, Apr 19, 2:45 PM MDT, 2 hours before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE DENVER CO 245 PM MDT TUE APR 19 2005 .SHORT TERM...FRONTAL SURGE ALONG FOOTHILLS AND ACROSS PALMER DIVIDE WITH SURFACE DEWPOINTS IN THE 40S OVER MUCH OF NORTHEAST PLAINS WITH SOME 50S EDGING INTO FAR NORTHEAST ZONES. MOST OF PLAINS STILL CAPPED AS SHOWN BY LATEST ACARS SOUNDINGS AND TEMPERATURES IN THE MID 60S SHOULD BE ENOUGH TO BREAK THIS CAP. CONVECTION ALREADY FIRING OVER MOUNTAINS AND ALONG FOOTHILLS WITH CUMULUS DEVELOPING ALONG THE FRONT ACROSS SOUTHERN DOUGLAS COUNTY INTO SOUTHERN LINCOLN COUNTY. STORMS COULD INITALLY HAVE A DIFFICULT TIME SURVIVING ONCE THEY MOVE OFF THE FOOTHILLS AND PALMER DIVIDE INTO THE MORE STABLE AIR ACROSS THE PLAINS. PROFILER SHOWING SHEAR IN ATMOSPHERE BECOMING MORE FAVORABLE AND FORECAST SOUNDINGS STILL INDICATING CAPES COULD REACH ABOUT 2000 J/KG. SEVERE STORMS STILL A POSSIBILITY PROVIDED THEY CAN SUSTAIN THEMSELVES. SEVERE TSTM WATCH ALREADY ISSUED FOR MUCH OF PLAINS. LOOKS LIKE MAIN THREAT WILL BE HAIL... THOUGH WILL NOT RULE OUT A BRIEF TORNADO DEVELOPING ALONG THE BOUNDARY ACROSS SOUTHERN DOUGLAS COUNTY INTO SOUTHERN LINCOLN COUNTY. LOW LEVEL MOISTURE STILL PROGGED TO INCREASE ACROSS PLAINS OVERNIGHT BEHIND NEXT SURGE. THIS LOOKS REASONABLE GIVEN POTENTIAL FOR STORMS TO LINGER NORTHEAST OF AREA WHICH COULD BRING OUTFLOW AND HIGHER DEWPOINTS BACK INTO NORTHEAST PLAINS. STILL SOME QG ASCENT AROUND OVERNIGHT TO KEEP SOME SHOWERS LINGERING. MAY SEE SOME FOG DEVELOPING AFTER MIDNIGHT...THOUGH THE SHOWERS COULD KEEP THE AREAL COVERAGE LIMITED. TEMPERATURES ACROSS MOUNTAINS TONIGHT WILL BE COLD ENOUGH FOR SNOW...BUT ONLY WEAK OROGRAPHICS EXPECTED. ON WEDNESDAY...UPPER LEVEL LOW OVER GREAT BASIN WILL BEGIN TO LIFT NORTHEAST. STILL SOME MID LEVEL QG ASCENT AROUND FOR SOME LINGERING SHOWERS. MODELS STILL SUGGESTING FRONT ALONG PALMER DIVIDE WILL TREK NORTHWARD WITH SURFACE LOW DEVELOPING NEAR DENVER. FOCUS FOR AFTERNOON STORMS WILL BE ALONG THIS FRONT WHEN SHORT WAVE MOVES ACROSS AND QG ASCENT INCREASES. APPEARS TO BE SUFFICIENT SHEAR FOR SOME SEVERE STORMS...WITH A FEW WEAK TORNADOES POSSIBLE ALONG BOUNDARY. STILL SOME QUESTIONS AS TO HOW FAR NORTH THE FRONT WILL MOVE. THERE MAY ALSO BE A CONTRAST IN TEMPERATURES...WITH THE WARMER READINGS SOUTH OF THE FRONT. WITH QUESTIONS ABOUND...BEST TO LEAVE CURRENT GRIDS AS IS. .LONG TERM...A PIECE OF THE H5 UPR LOW WL PULL EWD INTO NRN NEBR. MDLS INDG ATM WL BCM MORE STBL AS CAA OCCURS IN THE LWR LVLS OF THE ATM. ETA DIV-Q OMEGA FIELDS ALL SHOWING DOWNWARD MOMENTUM AS WELL AND AS A RESULT...AFTN CONVECTION WL PROBABLY BE ON THE DOWNTURN. TEMPS NR THE SFC ARE ON THE ORDER OF 5 DEGREES COLDER...SO TEMPS WL RMN IN THE 60S OVR MOST OF THE PLAINS WITH WK ELY UPSLOPE WINDS. AFTER SOME DRYING THURS MRNG...MID LVL MSTR WL MOV BACK INTO THE AREA. OVERALL FCST SNDS WL BE DRIER IN THE LWR LVLS AND ANY TSTMS WHICH DVLP MAY BE MORE CAPABLE OF PRODUCING WIND THAN THE STORMS OF TUES OR WED. CAPE IS FAIRLY MODEST...BUT CANNOT RULE OUT A SVR STORM OR TWO. WL KEEP CUR ISOLD POPS GOING WITH A LTL MORE CLDS THAN IN PRVS GRIDS. DRYING WLY WINDS AND MID LVL WARMING WL BEGIN FRIDAY AS MOST OF THE UPR LVL ENERGY SHIFTS INTO THE GREAT LAKES REGION. THUS...FCST FOR FRIDAY CALLS FOR DRY WEATHER. TEMPS WL CONTINUE TO BE NEAR SEASONAL NORMS IN THE 60S WITH COOL ELY WINDS NR THE SFC. QUITE A BIT OF MID AND HIGH MSTR WL CONTINUE TO SIFT INTO THE AREA FM A WEAK CUTOFF LOW OVR NRN UTAH...WL GO A LTL CLOUDIER THAN GDNC IN FRIDAY SKY GRIDS. SATURDAY THRU EARLY NEXT WEEK...NEW EXTENDED GFS IS FAIRLY PROGRESSIVE THROUGHOUT THE LONG TERM PERIOD. A FAST MOVING NEGATIVE TILT TROF IS PROGGED BY THE OPERATIONAL GFS TO MOVE THRU THE AREA SUNDAY NIGHT. SURPRISINGLY...MOST ENSEMBLE MEMBERS AGREE WITH THIS SOLN AND EVEN HAS SOME CORRELATION WITH THE EURO MDLS. WL PUT SOME LOW POPS IN FOR SUNDAY NIGHT AND MONDAY. && .BOU...NONE. && DL/046

THE STORMS WILL THEN MOVE TO THE NORTH AND NORTHEAST AND SPREAD ACROSS THE REST OF THE URBAN CORRIDOR AND NORTHEAST PLAINS DURING THE LATE AFTERNOON AND EVENING HOURS. STORMS THAT DO DEVELOP MAY BECOME SEVERE WITH LARGE HAIL UP TO 2 INCHES IN DIAMETER...WIND GUSTS TO 60 MPH AND EVEN A BRIEF TORNADO. A WEAK COLD FRONT IS LOCATED ALONG THE FOOTHILLS AND PALMER DIVIDE REGION...AND WILL ACT AS THE INITIAL FOCUS FOR THUNDERSTORM DEVELOPMENT AS LOW LEVEL MOISTURE AND WINDS CONTINUE TO CONVERGE ALONG THIS BOUNDARY. IN ADDITION...THE ATMOSPHERE WILL BECOME VERY UNSTABLE AS THE SHEAR PROFILE BECOMES MORE FAVORABLE FOR SEVERE STORMS. A BRIEF TORNADO CANNOT BE RULED OUT ALONG THIS BOUNDARY... MAINLY OVER THE SOUTHERN PORTIONS OF THE DENVER METRO AREA AND ACROSS DOUGLAS AND WESTERN ELBERT COUNTIES. AN UPPER LEVEL DISTURBANCE WILL ALSO AID IN THE DEVELOPMENT OF THE STORMS. .DAYS TWO THROUGH SEVEN...WEDNESDAY THROUGH MONDAY ANOTHER ROUND OF THUNDERSTORM ACTIVITY IS EXPECTED WEDNESDAY AFTERNOON. LOW CLOUDS AND FOG WILL BE WIDESPREAD ACROSS THE PLAINS WEDNESDAY MORNING...WHICH WILL DELAY THE ONSET OF CONVECTION SLIGHTLY. BUT BY MID AFTERNOON...STEEP LAPSE RATES ALONG WITH CONTINUED EASTERLY SURFACE WINDS WILL CREATE A FAVORABLE SCENARIO FOR SEVERE THUNDERSTORMS IN THE AFTERNOON. THE NORTHEAST PLAINS EAST AND NORTH OF FORT MORGAN STAND THE BEST CHANCE OF SEVERE WEATHER WITH THE PRIMARY THREAT BEING LARGE HAIL. A FEW SHORT LIVED TORNADOES CANNOT BE RULED OUT...BUT THE SHEAR PROFILE WILL NOT BE AS STRONG AS TODAY. A DRIER AND WARMER WEATHER PATTERN WILL GRADUALLY BECOME REESTABLISHED TOWARD THE WEEKEND. .SPOTTER INFORMATION STATEMENT... SPOTTER ACTIVATION MAY BE NEEDED AFTER 2 PM THIS AFTERNOON ACROSS MUCH OF NORTHEAST COLORADO. OPTIONAL NAMES
