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 Apr 3, 1:45 AM MST, 1 hour 15 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE PUEBLO CO 245 AM MDT TUE APR 3 2012 .UPDATE... .SHORT TERM...HAVE PUT OUT A SHORT FUSE HIGH WIND WARNING DUE TO PERSISTENT GUSTS OVER 60 MPH HERE AT KPUB AND AT A FEW SPOTS IN EL PASO AS WELL. WIDESPREAD WINDS OVER 50 MPH STILL BEING OBSERVED. ONGOING PRECIP IS BRINGING SOME HIGHER MOMENTUM AIR TO THE GROUND...AND THIS SHOULD CONTINUE FOR AT LEAST THE NEXT SEVERAL HOURS BEFORE WINDS GRADUALLY QUIET DOWN. WINTER HIGHLIGHTS LOOK ON TRACK FOR MOST PART. NAM IS SHOWING EXTREMELY HEAVY SNOW OVER THE SRN MTS AND ESPECIALLY SPANISH PEAKS REGION. WOULD NOT BE SURPRISED TO SEE SPOTS LIKE CUCHARA GET WELL IN EXCESS OF 2 FEET FROM THIS STORM. ROSE && .PREV DISCUSSION... /ISSUED 1128 PM MDT MON APR 2 2012/ AVIATION... IFR CIGS/VIS EXPECTED TO IMPACT THE TAF SITES FROM TONIGHT INTO TUESDAY...ESPECIALLY AFTER 07Z/3RD AS INTENSE STORM SYSTEM SLOWLY MOVES ACROSS NORTHERN NEW MEXICO. IN ADDITION...GUSTY NORTH WINDS IN THE 25 TO 45 KT RANGE SHOULD CONTINUE AT BOTH KCOS AND KPUB TAFS SITES TONIGHT. IT NOW APPEARS THAT THE HEAVIEST SNOW FOR KCOS AND KPUB SHOULD BE NOTED FROM 07Z-15Z AND THEN POSSIBLY AGAIN FROM 21Z TUESDAY TO 03Z WEDNESDAY. KALS...KCOS AND KPUB COULD ALL EXPERIENCE SOME ACCUMULATING SNOW FROM AFTER MIDNIGHT TONIGHT INTO TUESDAY. PREV DISCUSSION... /ISSUED 857 PM MDT MON APR 2 2012/ UPDATE... WILL ALLOW HIGH WIND WARNING TO EXPIRE AS ONLY AREA EXCEEDING 50 KNOT GUSTS THE PAST 2 HOURS HAS BEEN HERE AT KPUB...WITH WINDS DIMINISHING SLIGHTLY ELSEWHERE. HRRR SUGGESTS SOME 40-45 KNOT GUSTS OVER EASTERN EL PASO AND NORTHERN PUEBLO COUNTIES STILL POSSIBLE THROUGH 05Z...AND PERHAPS SOME BRIEF CONVECTIVE OUTFLOW WINDS TO AROUND 45 KNOTS ACROSS PROWERS AND BACA COUNTIES FROM TSRA IN KS. PRECIP A LITTLE SLOW TO GET GOING THIS EVENING WITH DRY SURFACE LAYER OVER EASTERN COLORADO AND DEEPEST LIFT JUST SOUTH OF THE AREA. WILL NUDGE POPS DOWNWARD MANY AREAS THROUGH 06Z WITH THIS UPDATE..ESPECIALLY KPUB/KCOS. 00Z NAM RAMPS UP PRECIP AFTER 06Z AS DEEPER MOISTURE PUSHES WESTWARD...WITH A PROLONGED PERIOD OF MODERATE/HEAVY RAIN AND SNOW CONTINUING WELL INTO TUES NIGHT. NAM 00Z QPF INDICATES LIQUID AMOUNTS OVER 2 INCHES OVER THE PALMER DIVIDE AND ACROSS THE SOUTHERN SANGRES/WETS AND I-25 CORRIDOR FROM PUEBLO SOUTHWARD...WHICH SUGGESTS FORECASTS OF 1 TO 2 FEET OF SNOW OVER THE HIGHER TERRAIN LOOK ON TRACK. KCOS/KPUB/CANON CITY PRECIP AMOUNTS STILL TRICKY WITH USUAL PRECIP MINIMUM NEARBY...THOUGH STRENGTH OF ISENTROPIC UPGLIDE SHOULD OVERCOME DOWNSLOPE FLOW FOR SEVERAL HOURS LATE TONIGHT INTO TUES. OVERALL TREND OF THE FORECAST LOOKS GOOD. --10 PREV DISCUSSION... /ISSUED 400 PM MDT MON APR 2 2012/ SHORT TERM... (TONIGHT AND TUESDAY) STRONG SPRING STORM TAKING AIM ON SOUTH CENTRAL AND SOUTHEAST COLORADO... MODELS IN REMARKABLE AGREEMENT WITH THE OVERALL DETAILS OF CLOSED UPPER LOW ACROSS EAST CENTRAL NEW MEXICO SHIFTING EASTWARD THEN NORTHEASTWARD INTO THE TX/OK PANHANDLE BY TUES AFTERNOON. FRONT HAS ALREADY SLAMMED THROUGH EASTERN CO EARLIER TODAY...WITH PEAK GUSTS IN EXCESS OF 60 MPH ACROSS PORTIONS OF EL PASO COUNTY. HRRR AND LOCAL 4 KM WRF INDICATED TWO PERIODS OF STRONGER WINDS...ONE THIS MORNING...AND ANOTHER THIS AFTERNOON INTO EARLY THIS EVENING. JUST PICKED UP A GUST TO 50 KTS AT KPUB AIRPORT AROUND 230 PM...SO PERHAPS THE SHORT RANGE MODELS DO HAVE A HANDLE ON THIS. THUS...WILL MAINTAIN HIGH WIND WARNINGS THROUGH 03Z. INTERESTINGLY...HRRR SUGGESTS CORE OF STRONGER WINDS MAY EXPAND ACROSS MORE OF THE SOUTHEAST PLAINS AND CONTINUE THROUGH 06Z...HOWEVER WITH TIGHTEST PRESSURE GRADIENT ALREADY PAST...WILL LEAVE CURRENT EXPIRATION AT 03Z AND LET LATER SHIFTS MONITOR THE TRENDS TO DECIDE IF EXTENSION IN TIME...OR EXPANSION IN AREA IS NECESSARY. LOCAL 4 KM WRF BACKED OFF SOME ON WIND GUSTS AFTER 03Z FOR ALL BUT PERHAPS EASTERN EL PASO COUNTY. OTHER AREA OF CONCERN FOR HIGH WINDS CONTINUES ALONG THE EASTERN SIDE OF THE SAN LUIS VALLEY AS WINDS ACCELERATE THROUGH THE PASSES IN THE SANGRES AND SPILLS INTO THE VALLEY. HRRR AND 12Z 4KM WRF STILL PAINT THIS SCENARIO IN THE LATEST RUNS...WITH PEAK WINDS OCCURRING NOW THROUGH 00Z...WITH GUSTS STARTING TO TAIL OFF BY 03Z. ALS HAD A WIND GUST TO 54 MPH AFTER NOON...WHICH IS VERY CLOSE. SUSPECT LOCAL AREAS TO THE WEST HAD HIGHER GUSTS. AGAIN...WRF KEEPS GUSTS UP AROUND 70 MPH THROUGH 03Z BEFORE TAILING OFF...SO CURRENT HIGHLIGHT LOOKS ON TARGET. FIRST LOBE OF ENERGY WILL ROTATE AROUND THE CLOSED LOW INTO SOUTHEAST COLORADO THIS EVENING. SNOW IS ALREADY OCCURRING ACROSS THE EAST FACING SLOPES OF THE SANGRES/WETS...THOUGH ITS BEEN PRETTY LIGHT SO FAR AS MOISTURE LAYER REMAINS SHALLOW. HOWEVER...RADARS TO THE SOUTH SHOW ECHOES EXPANDING ACROSS NORTHEAST NM WITH SOME EMBEDDED CONVECTION EVIDENT VIA LIGHTNING STRIKES. SHOULD SEE THIS BAND OF SHOWERS SPREAD NORTHWARD THROUGH THE EVENING WITH SNOW SPREADING NORTHWARD AND RAMPING UP ACROSS THE PIKES PEAK AREA AFTER 03-06Z. NICE ISENTROPIC UPGLIDE EVIDENT IN BOTH NAM AND GFS ON THE 300K SFC...AND MODELS IN GOOD AGREEMENT WITH HEAVY QPF AMOUNTS ACROSS A LARGE PORTION OF THE SOUTHEAST PLAINS THROUGH TUESDAY...PARTICULARLY NEAR THE MOUNTAINS. SNOW LEVELS WILL START OFF AROUND 7000 FEET...BUT DROP TO AROUND 5000 FEET OVERNIGHT. TIMING OF THE DROP IN TEMPERATURES AND THE RESIDUAL WARMTH OF THE GROUND WILL PLAY A BIG ROLE IN HOW MUCH SNOW ACCUMULATES ACROSS THE LOWER ELEVATIONS OF THE I-25 CORRIDOR SUCH AS SOUTHERN EL PASO AND PUEBLO COUNTIES. HOWEVER...WITH GOOD MODEL CONSENSUS AND IMPRESSIVE TROWAL ALOFT EXPECTED TO OVERWHELM DOWNSLOPE OFF THE PALMER AT LEAST THROUGH THE 06Z TO 15Z WINDOW...HAVE OPTED TO ISSUE A WINTER WEATHER ADVISORY FOR THE LOWER ELEVATIONS OF THE I-25 CORRIDOR...INCLUDING COLORADO SPRINGS AND PUEBLO. SNOWFALL AMOUNTS WILL LIKELY EXHIBIT A WIDE RANGE WITH SOME MELTING OFF ROAD SURFACES AT TIMES...BUT ANYWHERE FROM 2 INCHES ON THE GRASS...TO AROUND 6 INCHES NEAR THE MOUNTAINS SEEMS PLAUSIBLE. WITH A PERIOD OF EAST TO NORTHEAST WINDS FUNNELING UP THE ARKANSAS RIVER...AND UPSLOPING ALONG THE WEST SIDE OF THE LA GARITAS/AND EASTERN SAN JUANS...WILL INCLUDE THESE AREAS IN A WINTER WEATHER ADVISORY AND RUN IT THROUGH 00Z. BIGGEST WINNER IN THIS EVENT WILL BE THE EAST SLOPES OF THE SANGRES AND WETS 40 TO 50 KTS OF NORTHEAST UPSLOPE WILL RESULT IN 1 TO 2 FEET OF SNOW...WITH HIGHER AMOUNTS ( UP TO 30 INCHES) ACROSS THE HIGHER ELEVATIONS. REMAINDER OF THE HEADLINES IN GOOD SHAPE. TROWAL EVENTUALLY PULLS OFF TO THE NORTHEAST ON TUESDAY WITH SNOW WINDING DOWN FROM SOUTHWEST TO NORTHEAST DURING THE DAY ON TUESDAY. -KT LONG TERM... (TUESDAY NIGHT-MONDAY) TIMING AND LOCATION OF UPPER LEVEL STORM LIFTING OUT ACROSS THE SE PLAINS TUESDAY NIGHT THE MAIN FORECAST PROBLEM... TUESDAY NIGHT-WEDNESDAY...SLIGHT MODEL DIFFERENCES ON TIMING AND LOCATION OF UPPER LOW LIFTING OUT ACROSS THE SE PLAINS CONTINUE AND HAVE TAILORED FORECAST TOWARDS THE NAM AND EC WHICH HAVE THE LOW ACROSS EXTREME NORTHEAST NEW MEXICO AT 00Z WED AND THEN SLOWLY LIFT IT OUT ACROSS WESTERN OKLAHOMA INTO CENTRAL OKLAHOMA THROUGH THE DAY ON WEDNESDAY. ONGOING WRAP AROUND PRECIPITATION ACROSS THE EASTERN MTS AND I-25 CORRIDOR TUESDAY AFTERNOON SLOWLY SHIFTS EAST AND DIMINISHES FROM WEST TO EAST OVERNIGHT...AS UPPER LEVEL FLOW BECOMES MORE NORTHWEST. COULD SEE SOME ADDITIONAL LIGHT ACCUMULATIONS OF A COUPLE OF INCHES ACROSS THE NORTH AND EAST FACING SLOPES OF THE EASTERN MTS AND ALONG WITH PALMER DVD AND RATON MESA TUESDAY EVENING WITH THINGS WINDING INTO WEDNESDAY MORNING. TEMPERATURES ALOFT WARM FROM WEST TO EAST THROUGH THE DAY ON WEDNESDAY...AS UPPER LEVEL RIDGING BUILDS INTO THE STATE WITH HIGHS WARMING BACK TO AT OR SLIGHTLY ABOVE SEASONAL AVERAGES...THOUGH HAVE TAPERED BACK HIGHS A TAD IN EXPECTED SNOW COVERED AREAS. WEDNESDAY NIGHT-MONDAY...WARMER AND DRIER WEATHER CONTINUES TO BE PROGGED THROUGH THE PERIOD...WITH MODERATE TO STRONG WESTERLY FLOW EXPECTED ACROSS THE REGION AS SEVERAL SHORT WAVES MOVE ACROSS THE NORTHERN ROCKIES. ONE WAVE MOVES ACROSS THE REGION THURSDAY NIGHT AND FRIDAY...WITH BREEZY TO WINDY CONDITIONS AND POSSIBLE CRITICAL FIRE WEATHER CONDITIONS ON FRIDAY...DEPENDING ON HOW MUCH PRECIP FALLS. PASSING WAVE SENDS A DRY COLD FRONT ACROSS THE PLAINS FRIDAY WITH SLIGHTLY COOLER TEMPERATURES ACROSS THE AREA ON SATURDAY. ANOTHER WAVE POSSIBLE MOVES ACROSS THE NORTHERN ROCKIES ON SUNDAY NIGHT...WITH A BACKDOOR COLD FRONT POSSIBLE BRINGING IN ENOUGH LOW LEVEL MOISTURE FOR A FEW SHOWERS ACROSS THE EASTERN PLAINS ON MONDAY. HOWEVER...WILL KEEP A DRY FORECAST IN TACT THROUGH THE PERIOD. -MW AVIATION... IFR CIGS/VIS EXPECTED TO AFFECT THE TAF SITES TONIGHT AS STRONG SYSTEM MOVES ACROSS NORTHERN NEW MEXICO. STRONG NORTH WINDS IN THE 30 TO 45 KT RANGE WILL CONTINUE AT KCOS AND KPUB BEFORE DECREASING TOWARDS 06Z. KALS WILL CONTINUE TO SEE EAST WINDS IN THE 25 TO 40 KT RANGE THROUGH EARLY EVENING WITH PERIODS OF BLDU. HEAVIEST SNOW WILL IMPACT KCOS AND KPUB BETWEEN 06Z-18Z PERIOD WITH POTENTIAL FOR A COUPLE INCHES OF SNOW...MAINLY ON GRASSY SURFACES AT KPUB...TO AROUND 2 TO 5 INCHES AT KCOS. WITH WARM GROUND...THERE WILL BE SOME MELTING AT TIMES AT KCOS...BUT PAVED SURFACES COULD BECOME SLUSHY AND SNOWPACKED UNDER THE HEAVIER SNOW BANDS. KALS COULD SEE AN INCH OR TWO AS WELL.
