The episode as NWS PUB wrote it up.
Heavy thunderstorm rain produced several areas of flash flooding over sections of southern Colorado.
The local office's own words before the first event, 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 the first event at Jul 19, 1:45 PM MST, 3 hours 55 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE PUEBLO CO 245 PM MDT THU JUL 19 2007 .SHORT TERM... (TONIGHT AND FRIDAY) ...HEAVY RAIN AND FLASH FLOODING POSSIBLE THIS EVENING... THUNDERSTORMS GOT OFF TO AN EARLY START TODAY AS THEY INITIATED ACROSS THE MOUNTAINS SHORTLY AFTER 11 AM WITHIN MOISTURE PLUME POSITIONED ACROSS WRN AND CENTRAL CO PER WV PICS. MEANWHILE...FRONTAL BOUNDARY HAS MOVED THROUGH THE MAJORITY OF THE SE PLAINS EARLIER THIS MORNING...WITH DEW POINTS IN THE LOWER 60S ACROSS THE LOWER ARKANSAS RIVER VALLEY (KLHX AND KLAA OBS). EVEN RICHER LOW LVL MOISTURE LIES ACROSS NE CO. AS WINDS BECOME MORE EASTERLY...DEW POINTS ARE FORECAST BY SHORT RANGE MODELS TO INCREASE INTO THE LOWER 60S ACROSS ALL OF THE SE PLAINS BY THIS EVENING...AND THIS CERTAINLY LOOKS PLAUSIBLE. LIGHT WINDS ALOFT WITHIN THE UPPER RIDGE ARE RESPONSIBLE FOR SLOW MOVEMENT TO THUNDERSTORMS...AND WITH MOISTURE INCREASING ACROSS THE EASTERN HALF OF THE FCST AREA (12Z UPPER AIR SOUNDINGS SHOWING PCPN WATERS 140% OF NORMAL IN KDEN SOUNDING)...HAVE OPTED TO ISSUE A FLASH FLOOD WATCH FOR THE EASTERN MOUNTAINS AND ADJACENT PLAINS. THESE AREAS WILL BE THE INITIAL FOCAL POINT FOR THUNDERSTORMS THIS AFTN. AS THUNDERSTORMS SET OUT OUTFLOW BOUNDARIES...THUNDERSTORMS SHOULD BEGIN TO SPREAD ACROSS THE ADJACENT PLAINS AFTER 21Z. VIS AND RADAR MOSAICS ALSO SHOWING A SFC BOUNDARY SAGGING SOUTHWARD...EXTENDING FROM NORTHERN EL PASO...TO NORTHERN CROWLEY...KIOWA...AND NORTHEAST PROWERS COUNTIES AS OF 19Z. THIS MAY BE THE TRUE FRONTAL BOUNDARY (EDGE OF DEEPER COOL AIRMASS) AS TEMPS TO THE NORTH ARE IN THE 70S. THIS BOUNDARY COULD ALSO BE THE FOCUS FOR THUNDERSTORMS...THOUGH PER SPC MESO-ANALYSIS PAGE...THERE IS STILL AROUND 100 J/KG OF CIN TO OVERCOME ACROSS THE ERN PLAINS. HOWEVER...WITH A COUPLE MORE HOURS OF SURFACE HEATING...CONVECTIVE TEMPS COULD BE ACHIEVED. THIS POSES SOME CHALLENGES FOR FLASH FLOOD POTENTIAL ACROSS THE SOUTHEAST PLAINS. ATMOSPHERIC MOISTURE IS CERTAINLY THERE...AND THINK RAINFALL RATES OF UP TO 2 INCHES PER HOUR WOULD BE POSSIBLE JUST ABOUT ANYWHERE ALONG/EAST OF THE MOUNTAINS. HOWEVER...SOIL MOISTURES ARE FAIRLY DRY...SO FOR NOW WILL LIMIT THE FLASH FLOOD WATCH TO AREAS MORE SUSCEPTIBLE TO RUN OFF PROBLEMS...COMPLEX TERRAIN OF THE SE MTS INCLUDING THE BURN SCARS...AND THE ADJACENT PLAINS. GIVEN THE SLOW MOVEMENT TO STORMS...URBAN AREAS LIKE KCOS...KPUB AND ALL THE I-25 CORRIDOR CITIES...COULD EXPERIENCE SOME FLASH FLOODING DUE TO QUICK RUN OFF WHICH CAN QUICKLY CHALLENGE DRAINAGE SYSTEMS. WILL MONITOR LATEST RADAR TRENDS AND MAY MAKE THIS A LAST MINUTE CALL. NEXT CONCERN IS FOR MARGINAL SEVERE WEATHER POTENTIAL...WITH DEW POINTS IN THE UPPER 50S AND LOWER 60S ACROSS THE PLAINS...AND EVEN 40S ACROSS THE WRN MTS/VALLEYS...CAPE VALUES ARE RUNNING AROUND 800-2000 J/KG. SO COULD SEE SOME MARGINAL SEVERE HAIL WITH THUNDERSTORMS. DEEP LAYER SHEARS ARE AROUND 20 KTS OR LESS...SO MAIN THREAT WOULD BE FOR PULSE TYPE SEVERE STORMS. THINK SEVERE HAIL SHOULD BE FAIRLY ISOLATED THOUGH. ALTHOUGH ITS DIFFICULT TO FIND AN UPPER LEVEL FEATURE TO HELP MAINTAIN THUNDERSTORMS OVERNIGHT...BOTH GFS/NAM HANG ON TO SOME QPF ACROSS THE MTS AND SRN AREAS THROUGH THE NIGHT AND INTO TOMORROW MORNING. CERTAINLY PLAUSIBLE AS THERE COULD BE SOME EMBEDDED WEAK SHORTWAVE...SO WILL MAINTAIN SOME ISOLATED POPS FOR THESE AREAS. MAY ALSO CONTINUE TO SEE SOME DEVELOPMENT ALONG THE FRONT OVERNIGHT ACROSS TX/OK PANHANDLE/NE NM. SO WILL MAINTAIN SOME LOW GRADE POPS ALONG THE SRN BORDER. NOT MUCH CHANGE FOR TOMORROW. UPPER RIDGE IS STILL POSITIONED OVER THE AREA...AND EASTERLY LOW LVL FLOW WILL KEEP MID 50 TO LOWER 60 DEW POINTS ACROSS THE EASTERN PLAINS AND ADJACENT EASTERN SLOPES. THIS COULD YIELD CAPES UP TO 1500-2000 +J/KG ACROSS THE EASTERN MOUNTAINS/PLAINS WHERE DEW POINTS STAY HIGH. MODEL SOUNDINGS DO LOOK A LITTLE DRIER IN THE MID AND UPPER LEVELS THOUGH...AND UPPER LEVELS WARM A BIT WHICH MAY HELP CUT DOWN ON THE CAPE. H7-H5 SPECIFIC HUMIDITIES STILL AROUND 6 G/KG...SO WOULD THINK POCKETS OF HEAVY RAINFALL WOULD AGAIN BE POSSIBLE. WILL LET NEXT SHIFTS MONITOR THE HEAVY RAIN POTENTIAL FOR FRI. IN THE MEANTIME...BUMPED UP POPS IN GRIDS FOR FRI TO AT LEAST SCT FOR THE MOUNTAINS/ADJACENT PLAINS. -KT .LONG TERM... (FRIDAY NIGHT THROUGH THURSDAY) FRI EVENING WITH UPSLOPE FLOW OVR THE SERN PLAINS...AND DEW POINTS PROBABLY IN THE MID TO UPR 50S...THE NAM MAY BE NOT BE SHOWING ENOUGH PCPN ALONG AND NR THE SERN MTS. THUS WL GO AHEAD WITH SCT POPS OVR ALL THE MTS AND HIGH VALLEY FOR THE EARLY EVENING...AND ISOLD POPS OVR THE SERN PLAINS. WOULD THEN EXPECT MOST IF NOT ALL OF THE PCPN ENDING FOR THE LATE NIGHT HOURS. FOR SAT IT LOOKS LIKE THE UPR RIDGE CENTER WL BE AROUND SERN WY...SHIFTING TO THE NORTHEAST INTO THE DAKOTAS BY MON AND CONTINUING TO SHIFT E INTO MN BY WED. DURING THIS TIME-FRAME...THERE WL CONTINUE TO BE ENOUGH MSTR FOR DAILY PCPN CHANCES OVR AND NR THE MTS. LOOKS LIKE TEMPS WL BE HOT AGAIN THIS WEEKEND AND INTO THE BEGINNING OF NEXT WEEK WITH 90S TO AROUND 100 DEGREES OVR THE SERN PLAINS. && .AVIATION... TSRA WILL AFFECT THE AIRPORTS AND FLIGHT ROUTES THROUGH 05Z. MVFR CIGS...LOCALLY HEAVY RAINFALL...ERRATIC WIND GUSTS UP TO 40 MPH AND SMALL HAIL WILL BE POSSIBLE WITH TSRA. MVFR TO IFR CIGS WILL DEVELOP ACROSS THE SOUTHEAST PLAINS AFTER 10Z AFFECTING THE KCOS AND KPUB TAF SITES. STRATUS WILL DISSIPATE BETWEEN 15Z-16Z FRI. -KT && .PUB WATCHES/WARNINGS/ADVISORIES... FLASH FLOOD WATCH UNTIL 11 PM MDT THIS EVENING FOR COZ072>088. && 31/28

THE MAIN THREAT WITH THUNDERSTORMS WILL BE SMALL HAIL AND HEAVY RAINFALL. THE GREATEST POTENTIAL FOR HEAVY RAIN WILL BE ACROSS THE SOUTHEAST MOUNTAINS AND ADJACENT PLAINS WHERE EASTERLY UPSLOPE FLOW WILL TRANSPORT INCREASING MOISTURE INTO THE SOUTHEAST MOUNTAINS. RAINFALL RATES OF UP TO 2 INCHES PER HOUR WILL BE POSSIBLE WITH THE STRONGER STORMS...AND WITH LIGHT WINDS THROUGHOUT THE DEPTH OF THE ATMOSPHERE...THUNDERSTORMS ARE EXPECTED TO BE SLOW MOVING...LEADING TO THE POTENTIAL FOR FLASH FLOODING. HEAVY RAINFALL CAN CAUSE ROCK AND MUD SLIDES IN THE MOUNTAINS AND CANYONS...AND MUD FLOWS ACROSS THE BURN SCARS SUCH AS THE HAYMAN...MASON GULCH...MATO VEGA...AND IRON MOUNTAIN. HEAVY RAINFALL IN URBAN AREAS CAN CAUSE QUICK RUN OFF WHICH CAN OVERWHELM DRAINAGE SYSTEMS LEADING TO FLASH FLOODING OF ROADWAYS...DRAINAGE DITCHES AND CREEKS...IN SPITE OF THE RECENT DRY CONDITIONS. ONE OR TWO SEVERE THUNDERSTORMS WILL BE POSSIBLE THIS AFTERNOON WITH HAIL UP TO PENNY SIZE AND WIND GUSTS APPROACHING 60 MPH. GIVEN THE SLOW MOVEMENT TO THUNDERSTORMS...THE STRONGER STORMS COULD CAUSE LOCAL ACCUMULATIONS OF SMALL HAIL UP TO A FEW INCHES DEEP. .DAYS TWO THROUGH SEVEN...FRIDAY THROUGH WEDNESDAY ISOLATED TO SCATTERED THUNDERSTORMS WILL BE POSSIBLE EACH AFTERNOON AND EVENING...MAINLY OVER THE MOUNTAINS. THE MAIN THREATS FROM STORMS WILL BE CLOUD TO GROUND LIGHTNING AND LOCALLY GUSTY WINDS. .SPOTTER INFORMATION STATEMENT... WEATHER CONDITIONS THAT MEET REPORTING CRITERIA FOR SPOTTERS WILL BE POSSIBLE ACROSS SOUTH CENTRAL AND SOUTHEAST COLORADO FROM 2 PM THROUGH 11 PM.
