The episode as NWS PUB wrote it up.
On June 4th, an isolate severe thunderstorm produced penny size hail in Security.
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 Jun 4, 2:26 AM MST, 10 hours 14 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE PUEBLO CO 326 AM MDT MON JUN 4 2007 .SHORT TERM... (TODAY AND TONIGHT) ONLY SUBTLE DIFFERENCES EXPECTED IN THE WEATHER TODAYVS THE PAST FEW DAYS. FCST AREA STILL UNDER NW FLOW ALOFT. WEAK PV LOBES IN RUC DATA...EVIDENCE OF WEAK UPPER LVL SHORTWAVE DISTURBANCES...WILL MOVE ACROSS THE AREA TODAY...WHICH SHOULD ONCE AGAIN KICK OFF AFTERNOON AND EVENING SHOWERS AND THUNDERSTORMS. SHOULD BE AN EARLY START TO THUNDERSTORMS OVER THE MOUNTAINS AGAIN WITH NEXT PV LOBE ALREADY MOVING THROUGH WRN CO. THUS STORMS WILL LIKELY BEGIN FIRING AROUND 11 AM OVER THE HIGHER MOUNTAINS...THEN SPREADING ACROSS THE ADJACENT PLAINS AFTER 1 PM. MID LVL TEMPS LOOK A LITTLE WARMER TODAY THAN YESTERDAY...SO MOST AREAS WILL EXPERIENCE A WARM UP OF AROUND 2 TO 4 DEGREES. CAVEAT TO THIS MAY BE OUT WEST WHERE SOME RESIDUAL CLOUD COVER FROM CONVECTIVE DEBRIS FROM MAY KEEP TEMPS SIMILAR TO YESTERDAYS READINGS. MOISTURE IN MODEL SOUNDINGS LOOK A LITTLE BETTER OVER THE WEST TODAY...THOUGH STILL LOOKING AT INVERTED V STRUCTURE TO MODEL SOUNDINGS. THUS...THUNDERSTORM THREAT OUT WEST WILL LIKELY BRING GUSTY WINDS UP TO 40 MPH...CLOUD TO GROUND LIGHTNING...WITH SOME LOCALIZED RAINFALL AMOUNTS OF UP TO .10. ACROSS THE SE PLAINS...LOW LVL MOISTURE STILL IN PLACE WITH AFTN DEW POINTS IN THE 40S TO AROUND 50 NEAR THE EASTERN BORDER. THIS YIELDS CAPES OF 800 TO 1500 J/KG ALONG THE EASTERN MTS/ADJACENT PLAINS AND LAS ANIMAS AND BACA COUNTIES. DEEP LAYER SHEARS LOOK SIMILAR TO A LITTLE STRONGER THAN YESTERDAY...RUNNING AROUND 25-30 KTS DEPENDING ON THE MODEL RUN. THUS...THINK PULSE TYPE SEVERE STORMS WILL BE POSSIBLE AGAIN TODAY IN THE SAME AREAS AS YESTERDAY. SPC HAS THIS AREA OUTLOOKED UNDER A SLIGHT RISK...WHICH AGREES WELL. HAIL UP TO 1 INCH IN DIAMETER WOULD BE THE PRIMARY SEVERE THREAT. THUNDERSTORM COVERAGE SHOULD BE GREATEST ALONG THE EASTERN MTS/ADJACENT PLAINS...WERE SCT POPS LOOK REASONABLE. ELSEWHERE ISOLATED POPS SHOULD SUFFICE. UPPER LEVEL SHORTWAVE EXITS SOUTHERN CO DURING THE EVENING...WHICH WOULD SUGGEST AN EARLIER END TO CONVECTION TONIGHT. NOT SURE I BUY THE NAM WHICH BLOWS UP CONVECTION ACROSS NE CO AFTER 06Z. VORTICITY MAXIMUM POPS IN THIS EVENING WHICH DOESN/T SEEM TO HAVE MUCH CONTINUITY WITH TIME AND ALSO DOESN/T REFLECT IN THE PV FIELDS. GFS SEEMS TO SUPPORT A DRIER SOLN AS WELL. THUS...THINK THIS IS AN ARTIFACT OF THE CONVECTIVE PARAMETERIZATION GETTING TURNED ON...AND HAVE DISCOUNTED FOR NOW. -KT .LONG TERM... (TUE THROUGH SUN) ...POTENTIAL FOR STRONG-SEVERE THUNDERSTORMS TUE AFTN/EVE... ...WINDY TO VERY WINDY CONDITIONS WED... ...POSSIBLE IMPACT FIRE WEATHER CONCERNS WED... TUE...THIS COULD BE AN INTERESTING DAY. WRF AND GFS CONTINUE TO BE AT ODDS WITH THE PRECIPITATION DEVELOPMENT...WRF GENERATES ALL KINDS OF CONVECTIVE PRECIPITATION IN THE AFTN AND EARLY EVE WHILE THE GFS DEVELOPS NOTHING. MIDDLE TO UPPER LEVEL RIDGE FLATTENS OUT OVER THE ROCKIES AS THE NEXT SIGNIFICANT WEATHER SYSTEM MOVES THROUGH THE GREAT BASIN. PLENTY OF FUEL SHOULD BE IN PLACE WITH PROJECTED SURFACE BASED CAPES OF 500 - 2000 J/KG AND LIFTED INDICES OF -2C TO -6C. DEEP VERTICAL SHEAR...0-6KM...INCREASE TO 40-45KTS. SO...THE POTENTIAL FOR ORGANIZED SEVERE THUNDERSTORMS... SUPERCELLS...WOULD BE POSSIBLE. A COUPLE OF NEGATIVE ASPECTS FOR THE DEVELOPMENT AND WILL NEED TO BE OVERCOME. FIRST...MIDLEVEL WARMING STARTS...SO AN INTENSIFYING THERMAL CAPPING INVERSION DEVELOPS OVER SOUTHEAST CO...WHICH COULD LIMIT SURFACE BASED INITIATION THUNDERSTORMS. HOWEVER...THERE IS NO CAP OVER THE MOUNTAINS...SO THE CONVECTIVE PRECIPITATION COULD DEVELOP OVER THE EASTERN CO MOUNTAINS AND INITIATE ADDITIONAL DEVELOPMENT AS OUTFLOW BOUNDARIES COLLIDING HELPS BREAK THROUGH THE CAP. ANOTHER KEY FACTOR IS THE LACK OF A NOTICEABLE SYNOPTIC SCALE FEATURE TO HELP ENHANCE CONVECTION. HARD TO DISCERN ANY MIDLEVEL SHORTWAVE TROUGH OR H3-H2 POTENTIAL VORTICITY LOBE TO ENHANCE LIFT. TOUGH CALL. IT COULD EITHER BE MOSTLY SUNNY OR SEVERE WEATHER. WILL MAINTAIN LOW POPS. WED...MODELS CONTINUE TO SUPPORT A SIGNIFICANT WEATHER SYSTEM MOVING THROUGH THE CENTRAL ROCKIES BEGINNING LATE TUE NIGHT AND THROUGH WED NIGHT. RELATIVELY DEEP SOUTHWESTERLY FLOW WILL BE INCREASING DURING TUE NIGHT. MOUNTAIN TEMPERATURES WILL LIKELY REMAIN STEADY OR SLOWLY WARM DURING THE NIGHT...ESPECIALLY THE EASTERN SLOPES OF THE EASTERN CO MOUNTAINS. SIGNIFICANT DRYING OCCURS IN THE H85-H5 LAYER ACROSS MUCH OF SOUTHERN CO AS THE SOUTHWEST FLOW CHINOOK STRENGTHENS. 80-130 KT H25 JET STREAK MOVES OVER MUCH OF CO...ESPECIALLY NORTHERN 1/2...WED AFTERNOON. MOUNTAIN WAVE POTENTIAL DEVELOPS ALONG WITH POSSIBLE GAP FLOW STRENGTHENING. H7 AND H5 WINDS INCREASE TO 45-50KTS AND 70-90KTS...RESPECTFULLY BY EARLY WED AFTN. COULD POSSIBLY SEE HIGH WIND CRITERIA REACHED IN THE MOUNTAINS HIGHER TERRAIN...ESPECIALLY MOUNTAIN PEAKS. 45-50KTS AT H7 OVER THE SAN LUIS VALLEY COULD SUPPORT WIND GUSTS APPROACHING 50KTS. ANY INSTABILITY VIRGA- BOMBS WOULD SUPPORT GUSTS POSSIBLY TO 50KTS ACROSS SAN LUIS VALLEY WED AFTN/EARLY EVE ALONG WITH BLOWING DUST. I WOULD NOT BE SURPRISED TO SEE HIGH WIND GUSTS ALONG THE LEE OF THE SANGRE DE CRISTO MOUNTAINS...WEST OF WESTCLIFF...LA VETA...ETC AND WEST OF THE I-25 CORRIDOR MAINLY FROM PUEBLO TO THE RATON MESA. SURFACE- PBL DRYLINE WILL BE ACROSS SOUTHEAST CO...BUT SHOULD QUICKLY RACE EASTWARD DURING THE MORNING AND WELL INTO THE CENTRAL PLAINS BY WED AFTN GIVEN THE MUCH DRIER AIR ALOFT MIXING TO THE SURFACE. DEW POINTS COULD GO FROM AROUND 50S TO 20S ACROSS THE SOUTHEAST CO PLAINS FROM WED MORNING TO THE AFTN. DAYTIME HUMIDITY LEVELS WILL BE WELL BELOW 20 PERCENT. THE COMBINATION OF ABOVE AVERAGE TEMPERATURES...WINDY-VERY WINDY CONDITIONS...AND LOW HUMIDITY LEVELS COULD CREATE CRITICAL FIRE WEATHER CONDITIONS. BLM STILL INDICATES FUELS ARE NOT CRITICAL GIVEN THE PAST WET WEATHER...SO THE PROBABILITY FOR FIRE WEATHER HEADLINES SHOULD BE LOW. THE GREATEST MOISTURE AND INSTABILITY WILL BE IN NORTHWEST CO TOWARDS THE CENTRAL MOUNTAINS. PLAN TO MAINTAIN CURRENT POPS/WX. THU THROUGH SUN...NO CHANGES TO PREVIOUS FORECAST. METZE && .AVIATION... THUNDERSTORMS WILL DEVELOP ACROSS THE MTS AROUND 17-18Z...AFFECTING THE KCOS TO KTAD CORRIDOR AND THE SAN LUIS VALLEY FLOOR (KALS VCNTY) BETWEEN 19-20Z. MAIN THREATS WITH THUNDERSTORMS FOR THE KCOS TO KTAD CORRIDOR AND SOUTHEAST PLAINS WILL BE BRIEF VFR TO MVFR CIGS AND HAIL UP TO NICKEL SIZE...BRIEF HEAVY RAINFALL...ERRATIC WIND GUSTS UP TO 35 MPH AND LIGHTNING. FOR THE WESTERN AREAS...WIND GUSTS UP TO 40 MPH...BRIEF LIGHT TO MODERATE RAINFALL UNDER VFR CIGS...AND LIGHTNING WILL BE THE PRIMARY THREATS. THUNDERSTORMS SHOULD END FOR MOST AREAS BY 04Z. && .PUB WATCHES/WARNINGS/ADVISORIES... NONE. && 31/17
