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 Apr 26, 5:26 PM MDT, 38 minutes earlier.
Area forecast discussion, Apr 26, 5:26 PM MDT, 38 minutes before
AREA FORECAST DISCUSSION...UPDATED NATIONAL WEATHER SERVICE PUEBLO CO 526 PM MDT THU APR 26 2012 .AVIATION...THERE IS APPROXIMATELY A 50 PERCENT CHANCE OF A THUNDERSTORM AFFECTING THE TAF SITES BETWEEN NOW AND 06Z. WIDELY SCT SHOWERS AND ISOLD TS CONTINUE TO MOVE FROM THE SW TO NE AT APPROXIMATELY 30 KT. SHOWERS AND TS WILL PRODUCE OCCASIONAL STRONG WIND GUSTS FROM THE W-SW...WITH GUSTS TO 40-50 KT POSSIBLE. BRIEF IFR-MVR CONDITIONS ARE POSSIBLE...ALONG WITH SMALL HAIL. STRONGER STORMS WILL BE POSSIBLE E OF THE I-25 CORRIDOR THIS EVENING. STORMS COULD CONTINUE TO DEVELOP E AND N OF KPUB-KCOS AS LATE AS 06-09Z. NOTE THAT WINDS WILL BE QUITE ERRATIC THIS EVENING AT KPUB AND KCOS...AS LOW LEVEL WINDS ARE FROM THE E-SE WHILE STORMS CONTINUE TO TRANSFER W-SW WINDS TO THE SURFACE. SO...EVEN AWAY FROM STORMS...WINDS WILL BE QUITE VARIABLE THIS EVE. ROSE && .PREV DISCUSSION... /ISSUED 205 PM MDT THU APR 26 2012/ SHORT TERM... (TONIGHT AND FRIDAY) ..MAIN FORECAST CONCERNS REVOLVE AROUND SEVERE POTENTIAL FOR PORTIONS OF THE SOUTHEAST PLAINS THROUGH THE OVERNIGHT HOURS... COMPACT CLOSED LOW CIRCULATION ACROSS AZ WILL CONTINUE TO LIFT TO THE NORTHEAST ACROSS SOUTHERN AND SOUTHEAST COLORADO BETWEEN 06Z AND 12Z. SE SFC WINDS HAVE ADVECTED LOWER 50 DEW POINTS INTO BACA COUNTY...WITH 40S ALONG THE ARKANSAS RIVER TO THE NORTH. MEANWHILE...SOUTHWEST WINDS HAVE DROPPED DEW POINTS INTO THE 20S ACROSS THE HIGH VALLEYS...WITH DEW POINTS DROPPING ACROSS THE NRN RATON MESA AND PALMER DIVIDE AS DRY LINE TAKES SHAPE. MODELS STILL PAINT THE SCENARIO OF A COUPLE OF WAVES OF CONVECTION DEVELOPING ACROSS THE MOUNTAINS AND MOVING OFF INTO THE SOUTHEAST PLAINS. FIRST WAVE IS CURRENTLY DEVELOPING ACROSS THE MTS NOW...AND EXPECT CONVECTION TO DEVELOP ALONG THE SFC TROF/DRY LINE BY 20-21Z. SPC MESO ANALYSIS CURRENTLY SHOWING CAPES OF AROUND 1000 TO NEAR 1500 J/KG ACROSS THE SOUTHEAST PLAINS WITH DEEP LAYER SHEARS RUNNING AROUND 40-50 KTS. HRRR...RUC13...AND NAM12 MIX THE DEW POINTS OUT ALONG THE I-25 CORRIDOR BACK INTO THE 30S...THOUGH HANG TOUGH WITH THE 40S-LOWER 50 DEW POINTS ACROSS THE SOUTHEAST COUNTIES OF KIOWA...BENT...PROWERS...AND BACA...AS WELL AS EASTERN PORTIONS OF CROWLEY...OTERO...AND LAS ANIMAS COUNTIES. INITIALLY LCLS WILL START OUT RATHER HIGH...WITH THE PROXY T/TD SPREADS RUNNING AROUND 30 DEGREES ACROSS THIS REGION. HOWEVER...WITH THE APPROACH OF THE UPPER TROF...STRENGTHENING SOUTHEASTERLY WINDS WILL ADVECT 40 DEW POINTS BACK INTO THE NRN I-25 CORRIDOR...WITH 50S TO LOWER 60 DEW POINTS ACROSS THE SOUTHEAST PLAINS. COUPLED WITH COOLING TEMPS ALOFT WITH INCOMING SYSTEM...THIS SHOULD AMP UP CAPE VALUES TO BETWEEN 1500-2500 J/KG...WITH HIGHEST VALUES ACROSS BACA COUNTY BY 06Z. HELICITIES INCREASE TO 500+ M2/S2 BY 06Z WITH FORCING FROM THE SYSTEM LIKELY TO WEAKEN OR BREAK THROUGH WHATEVER CAP REMAINS. THUS...SEVERE WEATHER EVENT LOOKS TO START OUT AS A LARGE HAIL...AND DAMAGING WIND SCENARIO THIS AFTERNOON...AND EVOLVE TO INCLUDE AN ISOLATED TORNADO POTENTIAL AFTER 9 PM ACROSS THE FAR EASTERN COUNTIES. THIS ATYPICAL LATE NIGHT TORNADO THREAT FOR THIS REGION SHOULD LAST UNTIL AROUND 2 AM. STILL THINK THE MAIN THREAT AREA WILL EXTEND EAST OF A LINE FROM LIMON...TO LA JUNTA...TO KIM. THOUGH IF RUC IS CORRECT IN SPREADING 40 TO LOWER 50 DEW POINTS BACK WESTWARD INTO THE I-25 CORRIDOR AFTER THE FIRST ROUND OF AFTERNOON THUNDERSTORMS...THEN PLENTY OF MOISTURE WILL BE AVAILABLE TO BOOST CAPES UP FOR THE I-25 CORRIDOR FROM AROUND PUB NORTHWARD FOR THE 2ND ROUND OF THUNDERSTORMS WHICH SPREADS OFF THE SOUTHEAST MOUNTAINS DURING THE LATE EVENING. IF THIS OCCURS...THEN HAIL TO NEAR 1 INCH IN DIAMETER ALONG WITH DAMAGING WINDS MAY BE POSSIBLE FOR KCOS AND KPUB AS WELL. WILL CONTINUE TO MONITOR THIS POTENTIAL AS SCENARIO EVOLVES. ACROSS THE REMAINDER OF THE AREA...WIDESPREAD SHOWERS AND THUNDERSTORMS WILL DEVELOP OVER THE MOUNTAINS THIS AFTERNOON WITH SNOW LEVELS DROPPING ACROSS THE MOUNTAINS DURING THE EVENING WHEN BEST FORCING WITH UPPER LEVEL SYSTEM MOVES THROUGH. COULD SEE ANYWHERE FROM 2 TO 6 INCHES OF SNOW ACROSS THE HIGHER PEAKS...WITH MAJORITY OF SNOWFALL ABOVE 10KFT. PRECIPITATION WILL LIFT OFF TO THE NORTHEAST WITH THE PARENT UPPER LOW ON FRIDAY WITH PRECIPITATION TAILING OFF ACROSS THE OROGRAPHICALLY FAVORED NORTHWEST FACING SLOPES OF THE SAWATCH AND MOSQUITOS IN THE MORNING. COULD ALSO SEE A PERIOD OF WRAP AROUND PCPN ACROSS THE SOUTHEAST PLAINS DURING THE EARLY MORNING...BUT THIS SHOULD DIMINISH BY AFTERNOON. OTHERWISE...COOLER TEMPERATURES FOR FRIDAY...THOUGH WITH GUSTY NORTHWEST TO WEST WINDS BEHIND THE DEPARTING SYSTEM...DEEP MIXING WILL OFFSET THE COOLING ALOFT SOME TO STILL YIELD TEMPS IN THE 70S. -KT LONG TERM... (FRIDAY NIGHT THROUGH THURSDAY) FRIDAY NIGHT AND SATURDAY NIGHT...CLOSED UPPER LOW OVER NORTHWEST WYOMING EARLY FRIDAY EVENING MEANDERS INTO THE WESTERN DAKOTAS THROUGH SATURDAY NIGHT. AT THE SURFACE...UPSLOPE FLOW CONTINUES ON THE SOUTHEAST CO PLAINS. NAM BREAKS OUT PRECIPITATION ALONG THE SOUTHEAST MOUNTAINS SATURDAY EVENING...BUT THEN PRECIPITATION AREAS SHIFT INTO NORTHEAST COLORADO AND FAR SOUTHEASTERN CO. GFS DOESN'T HAVE MUCH QPF OVER THE MOUNTAINS...BUT HIGHLIGHTS NORTHEAST AND FAR SOUTHEAST CORNER OF THE STATE LATE SATURDAY EVENING. GIVEN THE UPSLOPE FLOW...COOL AIR ALOFT AND STEEP LAPSE RATES...KEPT SOME LOW POPS IN ALONG THE MOUNTAINS AND SPREAD EASTWARD ONTO THE PLAINS SATURDAY NIGHT. TEMPERATURES SATURDAY SHOULD BE FAIRLY COOL. KEPT THE PLAINS IN THE MID 50S TO MID 60S FOR HIGHS DESPITE A LARGE SPREAD IN THE GUIDANCE HIGHS. SUNDAY AND SUNDAY NIGHT...GFS/ECMWF STILL BULLISH WITH PRECIPITATION DEVELOPING ACROSS THE SOUTHEAST PLAINS SUNDAY EVENING WITH SHORT WAVE MOVING ACROSS SOUTHERN COLORADO. NOT AS COOL WITH HIGHS WARMING INTO THE LOWER 60S TO LOWER 70S ON THE PLAINS. MONDAY-TUESDAY...GFS/ECMWF BOTH CONTINUE TO SHOW WEST TO SOUTHWEST FLOW ALOFT OVER COLORADO EARLY IN THE WORK WEEK AHEAD OF A STRONGER TROF PROGGED TO MOVE THROUGH WY WEDNESDAY. DESPITE WARMER AND DRIER AIR MOVING INTO THE FORECAST AREA...MODELS SHOW SOME MID LEVEL MOISTURE AND A FEW WEAK WAVES TRIGGERING SHOWERS/THUNDERSTORMS OVER THE MOUNTAINS. WEDNESDAY-THURSDAY...UPPER LEVEL SHORTWAVE TROF MOVES EAST ACROSS WY WEDNESDAY. AT THE SURFACE...COLD FRONT MOVES SOUTHEAST THROUGH THE PLAINS WEDNESDAY NIGHT. DRY LOW LEVEL AIRMASS ON THE PLAINS KEEPS SHOWER ACTIVITY TIED TO THE MOUNTAINS. TROF AXIS SHIFTS EAST INTO THE PLAINS STATES WITH RIDGE BUILDING OVER CO ON THURSDAY. 40 AVIATION... A COUPLE OF ROUNDS OF -TSRA MAY AFFECT KCOS AND KPUB TAF SITES...ONE LATE THIS AFTERNOON...AND ANOTHER DURING THE EVENING AS THE POTENT UPPER LEVEL STORM SYSTEM MOVES THROUGH THE REGION. FIRST ROUND OF THUNDERSTORMS WILL PRODUCE ERRATIC GUSTY WINDS UP TO 40 KTS...ALONG WITH LIGHTNING AND BRIEF HEAVY RAINFALL. THE 2ND ROUND WHICH WILL SPREAD OFF THE MTNS INTO THE TAF SITES AROUND/AFTER 02Z...COULD BE STRONGER WITH THE POTENTIAL TO PRODUCE SOME SMALL HAIL UP TO 1 INCH IN DIAMETER AS WELL AS GUSTY ERRATIC WINDS. THUNDERSTORMS SHOULD END FOR BOTH KPUB AND KCOS AROUND 06Z WITH NORTH WINDS GUSTING TO 25 TO 30 KTS. BEST WINDOW FOR -TSRA AT KALS WILL BE FROM 01Z-04Z...WITH A ROUND OF GUSTY WINDS...AND LIGHTNING AND BRIEF MODERATE RAINFALL THE MAIN THREATS. MTN AREAS WILL SEE WIDESPREAD MTN OBSCURATIONS THROUGH THE EVENING WITH POTENTIAL FOR 2-6 INCHES OF SNOW DURING THE OVERNIGHT HOURS ACROSS THE HIGHER PEAKS. GUSTY NORTH TO NW WINDS WILL CONTINUE AT THE TAF SITES THROUGH FRIDAY...WITH VFR CONDITIONS. -KT && .PUB WATCHES/WARNINGS/ADVISORIES... NONE. && 44/10
