Local storm reports filed while the alert was in force, from inside its polygon or its counties.
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 12:00Z, 9.4 hours before the alert went out and 220 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.

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 Pueblo, CO wrote its last area forecast discussion before this severe thunderstorm warning went out at May 1, 2:42 PM MDT, 42 minutes earlier.
Area forecast discussion, May 1, 2:42 PM MDT, 42 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE PUEBLO CO 242 PM MDT TUE MAY 1 2007 .SHORT TERM... (TONIGHT AND WEDNESDAY) ...RELATIVELY ACTIVE WEATHER PATTERN OVER THE NEXT 24 HOURS... ...POTENTIAL MODERATE WARM RAINFALL OVER SNOW PACK TONIGHT... CURRENTLY...WATER VAPOR IMAGERY AND RUC MODEL UPPER AIR ANALYSES SHOWED DIRTY RIDGE OVER SOUTHERN AND CENTRAL ROCKIES WITH MINOR SHORTWAVES RIPPLING THROUGH THE WEAK FLOW. OLD CLOSED LOW WAS OVER THE CENTRAL PLAINS. THE NEXT SYSTEM TO WATCH WAS ABOUT TO ENTIRE THE DESERT SOUTHWEST. REGIONAL IR SATELLITE AND RADAR IMAGERY HAD ISOLATED-NUMEROUS SHOWERS AND THUNDERSTORMS POPPING OVER THE MOUNTAINS AND ADJACENT LOWER ELEVATIONS AROUND 1100 AM...WHICH IS ON-TIME FOR SUMMERTIME CONVECTIVE PRECIPITATION. CELLS HAVE BEEN NEARLY STATIONARY GIVEN THE WEAK STEERING FLOW ALOFT. AIR MASS PRETTY MOIST CONSIDERING IT IS EARLY MAY. REGIONAL 12Z/01 SOUNDING OBSERVATIONS HAD 150-200 PERCENT ABOVE NORMAL FOR PRECIPITABLE WATER INDICES. NOW...THAT IS 0.50 TO 0.70 INCHES...BUT IT IS STILL RELATIVELY MOIST FOR THIS TIME OF THE YEAR. SURFACE DEW POINTS ARE NOT TOO BAD EITHER...WITH 20S/30S IN THE MOUNTAINS AND 40S/50S ACROSS SOUTHEAST CO PLAINS. TONIGHT...BIG CHALLENGE WITH WHAT WILL REALLY HAPPENED. MIDLEVEL RIDGE IS KNOCKED DOWN OR SHIFTS EASTWARD WITH THE ADVANCING CLOSED LOW OVER THE DESERT SOUTHWEST. THE LATE AFTERNOON AND EVENING WILL CONTINUE TO HAVE ISOLATED - NUMEROUS SHOWERS AND THUNDERSTORMS OVER MUCH OF SOUTH CENTRAL AND SOUTHEAST CO THANKS TO INSTABILITY... MOISTURE...HEATING...AND WEAK DISTURBANCES. THE MAIN IMPACT WEATHER WOULD BE HAIL UP TO 1/2 INCH IN DIAMETER...WIND GUSTS UP TO 45 MPH...MODERATE TO HEAVY RAIN...AND CLOUD TO GROUND LIGHTNING. AFTER MIDNIGHT...THE CLOSED LOW MOVES THROUGH CENTRAL/SOUTHERN AZ/NM. MUCH OF THE BETTER SYNOPTIC SCALE ASCENT WOULD BE FOCUSED FURTHER SOUTH OF SOUTHERN CO. THERE IS HINTS OF WEAK MIDLEVEL ISENTROPIC ASCENT AND THIS COMBINED WITH MOISTURE AND INSTABILITY IS PROBABLY SETTING OFF CONVECTIVE BOMBS IN THE WRF AND GFS DATA. HARD TO SAY EXACTLY WHERE THE PRECIPITATION SHIELD WILL FORM TONIGHT. MY GUT SAYS THE SYNOPTIC SCALE ASCENT PRECIPITATION SHIELD...MESOSCALE CONVECTIVE SYSTEM...WILL BE ACROSS NM AND THE REMNANTS WILL DISSIPATE AS IT MIGRATES NORTHWARD INTO SOUTHERN CO. ACTUALLY...IT WOULDN/T BE SURPRISED TO SEE THE RADAR NOT SHOWING MUCH ACTIVITY ACROSS SOUTHERN CO AFTER MIDNIGHT. HOWEVER...THERE IS STILL THE POTENTIAL FOR STEADY LIGHT TO MODERATE RAINFALL ACROSS THE MOUNTAINS/HIGH VALLEYS TONIGHT. THIS BRINGS UP SOME IMPACT WEATHER/HYDRO ISSUES GIVEN RELATIVELY WARM RAINFALL ON SNOW PACK POTENTIAL. THE BEST I CAN TELL IS THE SNOW PACK LEVEL STARTS AROUND 8K TO 10K FT MSL. PROJECTED FREEZING AND WET BULB ZERO HEIGHTS ARE PRETTY HIGHT...11K TO 14K FT MSL...POSSIBLY LOWERING TO AROUND 10K FT MSL LATER TONIGHT. THUS... THERE IS A POTENTIAL FOR WARM RAINFALL ON MELTING SNOW PACK DURING THE NIGHT. DEL NORTE AT RIO GRANDE IS 2.5 FEET AWAY FROM FLOOD STAGE...HOWEVER...THAT PART OF THE RIVER CAN HANDLE A LOT OF WATER. WGRFC RAN A QUICK MODEL FOR 0.50 INCH OF WATER IN 12 HOURS WITH SNOW MELT OVER THE BASIN...AND THE DEL NORTE ONLY INCREASED 1000 CFS... WHICH FALLS SHORT OF BANKFUL. HOWEVER...1-2 INCH RAINFALL OVER A 12 HOUR PERIOD COULD CAUSE PROBLEMS IN LOCAL AREAS. WILL HOLD OFF ISSUING A FLOOD WATCH FOR RAIN ON SNOW PACK MELTING...BUT MENTION HERE AND HAZARDOUS WEATHER OUTLOOK. MOUNTAIN PEAKS COULD SEE 1 TO 4 INCHES OF SNOWFALL TONIGHT AND THIS IS COVERED WELL IN THE DIGITAL FORECAST DATABASE. WEDNESDAY...CLOSED LOW CONTINUES MOVING EASTWARD ACROSS NM AND INTO THE SOUTHERN PLAINS. RELATIVELY HIGH MOISTURE CONTENT CONTINUES ACROSS THE CENTRAL ROCKIES WITH THE POTENTIAL FOR MORE SHOWERS AND THUNDERSTORMS TO DEVELOP. MIDLEVEL FLOW IS RELATIVELY WEAK...SO SHOWERS AND THUNDERSTORMS WILL BE MOVING SLOWLY. H7-H5 SPECIFIC HUMIDITY VALUES AROUND 5 G/KG. THE MAIN THUNDERSTORM IMPACT WEATHER SHOULD BE MODERATE TO HEAVY RAIN...HAIL UP TO 1/2 INCH...WIND GUSTS UP TO 45 MPH...AND CLOUD TO GROUND LIGHTNING. CONSIDERING THERE SHOULD BE MORE CLOUDS AND THIS AFTERNOON/S TEMPERATURES BARELY GOT INTO THE 70S...I HAVE COOLED OFF MAXIMUM TEMPERATURES FOR WEDNESDAY. METZE .LONG TERM... (WEDNESDAY NIGHT THROUGH TUESDAY) ...UNSETTLED WEATHER THROUGH THE EXTENDED PERIOD... TRICKY FORECAST FOR THE EXTENDED PERIOD AS A LONGWAVE TROUGH MOVES INTO THE WESTERN HALF OF THE COUNTRY. WED NIGHT...UPPER DISTURBANCE SLIDES ACROSS THE TX AND OK PANHANDLES AND WEAKENS...WITH EASTERLY FLOW IN THE EVE STILL PRODUCING CONVECTION FOR THE E PLAINS. ONGOING GRIDS HAD SCATTERED POPS FOR THE PLAINS...ISOLATED ELSEWHERE AND SAW NO NEED TO ALTER THIS. MILD TEMPS EXPECTED DUE TO EXTENSIVE CLOUD COVER FOR MUCH OF THE NIGHT. THURSDAY AND FRIDAY...DIFFICULT DAYS HERE AS THE UPPER LOW DROPS INTO THE PAC NW. MODELS INDICATE THAT DRIER AIR WILL GET ENTRAINED IN THE UPPER FLOW ACROSS THE STATE...WITH MUCH OF THE CWA PERHAPS STAYING DRY. ALSO...LATEST GUIDANCE POINTS TO THU AND FRI HAVING THE HIGHEST MAX TEMPS THROUGH THE EXTENDED WHICH SEEMS REASONABLE SINCE AT FIRST GLANCE MUCH OF THE CWA WILL BE IN A DOWNSLOPE SITUATION. HOWEVER...LOT OF FACTORS TO JUGGLE. FIRST IS THE DRY LINE ALONG THE CO/KS BORDER. CURRENTLY IT LOOKS AS IF IT WILL ONCE AGAIN RIDE THE STATE LINE...BUT SOME WAVERING WEST OR EAST IS ALMOST ASSURED. CAPE CHARTS INDICATE 1000 TO 1500 J/KG BY THU AFTN...ALONG WITH 40 TO 50 KTS BULK SHEAR. SO IF STORMS CAN GET GOING...SEVERE POTENTIAL IS HIGH. THEN ON FRI...UPPER JET STARTS DIGGING AND SWINGING AROUND THE SOUTHERN END OF THE TROUGH...ADDING FRONT LEFT QUAD DYNAMICS TO THE EQUATION. THEREFORE...ADDED ISOLATED POPS MOST AREAS BOTH DAYS WHERE IT WAS DRY...BUT DID NOT GO HIGHER JUST YET BECAUSE OF UNCERTAINTY. NEXT CREW CAN ACT UPON THIS IF THERE IS RUN TO RUN CONTINUITY. SATURDAY THROUGH TUESDAY...THE UPPER TROUGH SPLITS...WITH THE SOUTHERNMOST UPPER LOW DROPPING DOWN ACROSS THE GREAT BASIN EARLY SAT AND THEN STALL OUT OVER UT AND AZ THROUGH MON...THEN EJECT TO THE N-NE ON TUE. MODELS ARE POINTING TO A GOOD AMOUNT OF PCPN OVER AN EXTENDED PERIOD. ONGOING FORECAST HAS A DAILY MENTION OF SHOWERS AND THUNDERSTORMS THROUGH THE END OF THE EXTENDED... AND THIS LOOKS TO BE THE BEST SOLUTION AT THIS TIME SINCE ACTUAL AMOUNTS WILL BE DICTATED BY WHERE THE LOW EVENTUALLY SETS UP. MOORE && .PUB WATCHES/WARNINGS/ADVISORIES... NONE. && 17/27

THUNDERSTORMS COULD BECOME STRONG...ESPECIALLY ALONG THE EASTERN SLOPES OF THE SOUTHEAST MOUNTAINS AND ADJACENT PLAINS AFTER 2 PM...WHERE THUNDERSTORMS WILL BE CAPABLE OF PRODUCING LOCALLY HEAVY RAINFALL...ALONG WITH WIND GUSTS UP TO 35 MPH...SMALL HAIL UP TO 1/2 INCH IN DIAMETER...AND DANGEROUS CLOUD TO GROUND LIGHTNING. ACROSS THE WESTERN MOUNTAINS AND HIGH VALLEYS...THE MAIN THREAT FROM THUNDERSTORMS WILL BE WIND GUSTS UP TO 45 MPH...DANGEROUS CLOUD TO GROUND LIGHTNING...AND BRIEF RAINFALL. A WEATHER DISTURBANCE WILL MOVE ACROSS COLORADO TONIGHT...CAUSING SHOWERS AND THUNDERSTORMS TO BECOME MORE NUMEROUS THIS EVENING... WITH WIDESPREAD SHOWERS CONTINUING AFTER MIDNIGHT. LOCALLY HEAVY RAINFALL WILL BE POSSIBLE WITH THE STRONGER STORMS...ESPECIALLY ALONG THE EASTERN SLOPES OF THE SOUTHEAST MOUNTAINS. LOCAL AREAS COULD EXPERIENCE PROBLEMS WITH INCREASED RUN OFF AND LOCALIZED FLOODING UNDER THE HEAVIER AND PERSISTENT SHOWERS. THERE WILL BE THE POTENTIAL FOR STEADY LIGHT TO MODERATE RAINFALL ACROSS THE EASTERN SAN JUAN...LA GARITA...AND SOUTHERN SANGRE DE CRISTO MOUNTAINS TONIGHT. SNOW PACK LEVEL IS AROUND 8000 FEET. THIS COMBINED WITH FREEZING AND SNOWFALL LEVELS AROUND 10000 FEET WILL SUPPORT RELATIVELY WARM RAINFALL IN MELTING SNOW PACK. IF THIS OCCURS...IT WILL FILL UP STREAMS AND RIVERS IN THESE LOCATIONS. THE RIO GRANDE ACROSS THE EASTERN SAN JUAN MOUNTAINS AND SAN LUIS VALLEY COULD START TO RISE LATER TONIGHT INTO WEDNESDAY. NUMEROUS RAIN AND SNOW SHOWERS WILL CONTINUE OVERNIGHT ACROSS THE WESTERN MOUNTAINS. SNOW LEVELS WILL DROP TO AROUND 10000 FEET AFTER MIDNIGHT...WITH 2 TO 5 INCHES OF SNOWFALL POSSIBLE ACROSS THE HIGHER ELEVATIONS BY EARLY WEDNESDAY MORNING. .DAYS TWO THROUGH SEVEN...WEDNESDAY THROUGH MONDAY SCATTERED AFTERNOON AND EVENING THUNDERSTORMS WILL DEVELOP WEDNESDAY OVER THE ENTIRE REGION...AND A FEW STORMS MAY PRODUCE LOCALLY HEAVY RAIN...MAINLY OVER THE INTERSTATE 25 CORRIDOR AND EASTERN MOUNTAINS.
