The episode as NWS PUB wrote it up.
Strong thunderstorms rumbled through southeast Colorado, and one produced a tornado.
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 17, 2:25 PM MST, 3 hours 36 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE PUEBLO CO 325 PM MDT FRI APR 17 2009 .SHORT TERM... (TONIGHT AND TOMORROW) ...CONCERN CONTINUES TO BE MAJOR SYNOPTIC CYCLONE CENTERED OVER KTAD...SNOW AND ISOLD SVR THREAT WILL CONTINUE.... CURRENTLY...RADAR CIRCULATION OF UPPER LOW IS LOCATED OVER KTAD AS I WRITE (230 PM). BOTH RUC AND NAM ANALYSIS FIELDS SHOW THIS MID LVL CIRCULATION PRETTY MUCH IN THE SAME AREA. BAND OF SNOW WHICH BROUGHT HEAVY SNOW TO THE PIKES PEAK REGION WAS MOVING NORTH...AND WAS JUST MOVING NORTH OF THE CWA BORDER. AN AREA OF NEW RAIN AND SNOW WITH EMBEDDED THUNDER...WAS CONTINUING TO EXPAND OVER THE WETS/SANGRES. THIS AREA OF PRECIP IS ASSOCIATED WITH THE UPPER LOW ITSELF. REST OF TODAY AND TONIGHT...LOW IS FCST TO MOVE LITTLE DURING THE NEXT 9 HOURS OR SO. NE 700 MB FLOW...ALTHOUGH MODEST...WILL CONTINUE OVER THE I-25 CORRIDOR DURING THIS TIME PD. THIS WILL KEEP UPSLOPE FLOW OVER THE E FACING SLOPES OF THE MTNS. WITH THE COLD AIR ALOFT AND ADDITIONAL VORT LOBES MOVE AROUND THE LOW...PERIODS OF SNOW SHOULD CONTINUE INTO TONIGHT. BEST QPF FIELDS CONTINUE TO INDICATE BEST SNOWFALL WILL OCCUR OVER THE PALMER DIVIDE OVER N EL PASO COUNTY. WITH TEMPS COOLING DOWN AFTER SUNSET...SNOW SHOULD HAVE AN EASIER TIME ACCUMULATING. AS MENTIONED IN THE FIRST PARAGRAPH...THE SNOW HAS LET UP OVER THE PALMER DVD...BUT I DONT BELIEVE THIS WILL LAST. I DO NOT KNOW IF IT WILL BE AS HEAVY AS EARLIER...BUT I DO BELIEVE IT WILL REDEVELOP BY LATER ON THIS AFTERNOON OR EARLY EVENING. THIS MAY ALREADY BE OCCURRING AS RADAR...AS OF 3 PM...WAS SHOWING MORE CONVECTION FIRING UP OVER SW EL PASO/S LINCOLN/CROWLEY COUNTY...AND IT WAS MOVING WNW TOWARDS THE GREATER KCOS REGION. WE WILL ALSO HAVE A THREAT OF SVR WX THIS AFTERNOON AND EARLY EVENING OVER THE PLAINS. WITH LAPSE RATES AOA 9C/KM OVER THE SE PLAINS AND WEAK BOUNDARIES OVER THE REGION...QUICK SPIN UPS WILL BE POSSIBLE WITH MINI SUPERCELLS. THE GREATEST THREAT WILL BE GENERALLY E OF HIGHWAY I-25 AND S OF HIGHWAY 50. WE HAVE SEEN QUITE A FEW TIGHT MESO ALREADY ON RADAR WHICH HAVE BEEN TRANSIENT IN NATURE. HAIL WILL ALSO BE A CONCERN...BUT IT WILL BE MARGINAL AT BEST. FOR TOMORROW...BY 12Z SAT...THE 500 MB LOW IS PRGD TO BE OVER THE KS/CO/OK BORDER AND SHEARING OFF TO THE NE. A BAND OF PRECIP WILL LIKELY EXIST FOR N EL PASO COUNTY NORTHEAST INTO NE CO. WITH NW 700 MB FLOW DEVELOPING OVER MOST OF THE REST OF THE REGION...PRECIP SHOULD BE DECREASING OVER THE REMAINDER OF THE REGION. TEMPS TOMORROW WILL SHOW A BIT OF VARIABILITY AS WHERE IT SNOWED IT WILL WARM UP ONLY GRADUALLY WHILE THE SFC WHICH RECEIVED RAIN WILL WARM UP A BIT QUICKER. /HODANISH .LONG TERM... (SATURDAY NIGHT THROUGH FRIDAY) SATURDAY NIGHT...UPPER LOW FORECAST TO BE OVER CENTRAL KANSAS BY 00Z SUNDAY...AND CONTINUING TO PULL EAST. NAM12 AND GFS40 HAVE SOME DEEP MOISTURE AND SCATTERED LIGHT PRECIPITATION OVER THE EASTERN HALF OF THE AREA EARLY IN THE NIGHT...BUT THAT SHIFTS TO THE EAST AFTER 06Z. HAVE CHANCE POPS OVER EASTERN AREAS THROUGH 06Z WITH ONLY A FEW HUNDREDTHS OF INCH OF LIQUID OR TENTHS OF INCHES OF SNOW. SUNDAY...NORTHWEST FLOW ON WEST SIDE OF LOW WILL KEEP MID LEVEL TEMPERATURES DOWN TO A FEW DEGREES EITHER SIDE OF 0 CELSIUS. WITH PARTLY CLOUD SKIES...TEMPERATURES SHOULD REACH THE 50S TO LOWER 60S HIGH VALLEYS AND PLAINS...AND 30S AND 40S MOUNTAIN LOCALES. MONDAY THROUGH FRIDAY...RIDGE WILL SLOWLY BUILD INTO THE AREA THROUGH THE WEEK WITH DAY TO DAY RISES IN TEMPERATURE MONDAY THROUGH WEDNESDAY...AS MID LEVEL TEMPERATURE ELEVATE TO BETWEEN 4 AND 8 DEGREES CELSIUS. NEXT SYSTEM FORECAST...AT THIS TIME...TO APPROACH ON FRIDAY...SO TEMPERATURES WILL BE WELL INTO THE 70S ACROSS THE PLAINS...WITH 60S HIGH VALLEYS...AND 40S AND 50S MOUNTAINS. -TLM- && .AVIATION... EXPECT LOW CIGS OVER ALL SITES TONIGHT WITH CONDITIONS GRADUALLY IMPROVING DURING THE DAY TOMORROW. CIGS COULD GET QUITE LOW TONIGHT GIVEN THE CLOUDS/FOG AND PRECIP. WINDS WILL GET GUSTY FROM A N COMPONENT...ESPECIALLY ACROSS KCOS THIS EVENING. ALL AREAS WILL LIKELY SEE ACCUM SNOWS...ESPECIALLY KCOS. && .PUB WATCHES/WARNINGS/ADVISORIES...
