What forecasters said that day
The local office's own words before this winter storm warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Denver/Boulder, CO wrote its last area forecast discussion before this winter storm warning went out at Nov 26, 2:45 AM MST, 1 hour 21 minutes earlier.
Area forecast discussion, Nov 26, 2:45 AM MST, 1 hour 21 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE DENVER CO 245 AM MST SAT NOV 26 2005 .SHORT TERM...SHOWERS POPPING UP OVER WESTERN COLORADO AS THE LEAD SHORTWAVE MOVES IN. INCREASED CLOUD COVER TODAY AND SPED UP THE ARRIVAL OF SHOWERS IN THE MOUNTAINS...THOUGH THERE COULD BE A BIT OF A BREAK BEHIND THIS FIRST TROUGH AXIS THIS AFTERNOON. WITH STRONG LIFT FROM THE UPSTREAM JET AXIS...STILL PRESSURE FALLS BACK BEHIND THIS FIRST TROUGH. THIS SHOULD KEEP PLAINS WINDS IN CHECK TODAY AND BETWEEN LIGHT WINDS AND SOME CLOUD COVER ON THE PLAINS AND COOLING ALOFT ARRIVING A FEW HOURS EARLIER IN THE MOUNTAINS...DROPPED TEMPS A BIT TODAY. MAIN WEATHER STILL SCHEDULED FOR TONIGHT AS STRONGER LIFT ARRIVES AND BROAD CYCLOGENESIS OCCURS ON THE PLAINS. THIS RESULTS IN A NORTH-SOUTH ORIENTED TROUGH ALOFT AND A LOW LEVEL CYCLONE THAT WILL BE SETTING UP WELL EAST OF COLORADO. NOT GOOD FOR PRECIPITATION ON THE PLAINS AS WE SHOULD KEEP A DOWNSLOPE LOW LEVEL COMPONENT THROUGHOUT. STILL SOME UPWARD FORCING IN A NEUTRAL ATMOSPHERE TONIGHT. THE STORM SHOULD BE GENERATING ITS OWN MOISTURE...ENOUGH TO BRING SNOW TO THE MOUNTAINS BUT MAYBE NOT ENOUGH TO OVERCOME THE DOWNSLOPE ON THE PLAINS. WILL STICK WITH CURRENT POPS ON THE PLAINS AS THERE COULD BE SOME SHOWER BANDS DESPITE THE DRY ENVIRONMENT. FOR THE MOUNTAINS IT LOOKS LIKE THERE SHOULD BE ENOUGH MOISTURE TO ALLOW FOR CONVECTION. THIS COULD BRING A PERIOD OF HEAVY SNOW IN THE MIDST OF OTHERWISE MEDIOCRE OROGRAPHIC SNOWFALL. THE WIND DIRECTION IS PRETTY FAVORABLE FOR THE RABBIT EARS PASS AREA...WILL GO AHEAD WITH A WINTER STORM WARNING FOR OUR SIDE OF THAT RANGE AS THERE SHOULD BE PLENTY OF SNOW CARRYING OVER. NOT SO CLEAR CUT FOR THE REST OF OUR MOUNTAINS AND A SNOW AND BLOWING SNOW ADVISORY WILL LIKELY SUFFICE UNLESS THE CONVECTION GETS CARRIED AWAY. .LONG TERM...FROM 12Z-18Z SUNDAY QUITE A BIT OF QG ASCENT WILL BE OVER THE CWA...BEING REPLACED BY INCREASING SUBSIDENCE AFTER 18Z. THE STRONGEST RISING MOTIONS ARE EXPECTED TO OUR SOUTH HOWEVER. THUS BEST PRECIPITATION CHANCES AT THE LOWER ELEVATIONS WILL BE SUNDAY MORNING. CURRENT GRIDS REFLECT THESE RELATIVELY LOW PRECIPITATION CHANCES AND TRENDS AND HAVE NOT BEEN MESSED WITH. AS STRONG CYCLOGENESIS COMMENCES TO OUR NORTHEAST ON SUNDAY...THE SURFACE WINDS OVER THE PLAINS WILL RESPOND DRAMATICALLY WITH RATHER WINDY CONDITIONS ANTICIPATED BY SUNDAY AFTERNOON WHICH SHOULD CONTINUE THROUGH SUNDAY NIGHT AND PERHAPS MUCH OF MONDAY. WILL HOLD OFF ON HIGH WIND HIGHLIGHTS AT THIS POINT IN TIME AS LATEST ETA HAS BACKED OFF A BIT ON TIGHT PRESSURE GRADIENT. ANOTHER STORY EXISTS FOR THE HIGH COUNTRY. EVEN THOUGH DECENT SYNOPTIC SCALE SUBSIDENCE IS EXPECTED UP THERE MOST OF SUNDAY AND MONDAY...OROGRAPHICS SHOULD BE QUITE GOOD THROUGH SUNDAY. COLD AIR AND LACK OF REALLY DEEP MOISTURE WILL BE THE LIMITING FACTORS IN THE OROGRAPHIC COMPONENT. HOWEVER MODELS ARE PREDICTING A PRETTY DECENT LAYER OF POTENTIAL INSTABILITY NEAR MOUNTAIN TOP WHICH SHOULD BE AROUND THROUGH SUNDAY BUT DECREASE SOME BY SUNDAY NIGHT. THIS FEATURE SUGGESTS THAT CONVECTION WILL GET THROWN INTO THE MIX IN THE MOUNTAINS SUNDAY... SOME OF WHICH WILL LIKELY SPILL OVER INTO NORTH AND MIDDLE PARKS. HAVE UPPED SNOW AMOUNTS IN THESE AREAS TO TRY TO ACCOUNT FOR THIS. ALSO NEEDED TO LOWER TEMPERATURES QUITE A BIT IN THE HIGH COUNTRY WITH THE EXPECTED COLD AIR ALOFT SUNDAY AND MONDAY. MADE ONLY A FEW CHANGES BEYOND MONDAY MAINLY TO WARM THINGS UP ON THE PLAINS AND REMOVE PRECIPITATION THREAT TUESDAY AS MODELS SUGGEST DRY DOWNSLOPE WINDS FOR THAT TIME FRAME. .BOU WATCHES/WARNINGS/ADVISORIES...
