NWS Pueblo, CO wrote its last area forecast discussion before the first event at Feb 2, 10:49 AM MST, 1 hour 11 minutes earlier.
AREA FORECAST DISCUSSION...UPDATED NATIONAL WEATHER SERVICE PUEBLO CO 1049 AM MST THU FEB 2 2012 .UPDATE... UPDATED THE HEADLINES TO INCLUDE THE UPPER ARKANSAS AND FREMONT AND PUEBLO COUNTIES. CURRENT DEWPOINT SPREADS SUGGEST THAT ONCE PRECIP GETS GOING OVER THE AREA...SHOULD SEE A FASTER CHANGEOVER TO SNOW. THIS WILL LEAD TO HIGHER SNOW AMTS OVER PUEBLO AND FREMONT. HIGHER SN AMTS WILL BE N OF HGWY 50. EXPECT SOME SN COVERED ROADS UP THE ARKANSAS...SO WILL PUT OUT A SN ADVISORY FOR HAZARDOUS ROAD CONDITIONS...ESPECIALLY TONIGHT AND FRI MORNING. ROSE && .PREV DISCUSSION... /ISSUED 911 AM MST THU FEB 2 2012/ UPDATE... AFTER REVIEWING 12Z MODEL DATA...HAVE DECIDED TO UPGRADE S EL PASO COUNTY...INCLUDING KCOS...TO A WARNING. MAIN CONCERN IS LOW SNOW- LIQUID RATIOS EARLY ON...BUT EXPECT ALL SNOW AFTER SUNSET TONIGHT...SO BULK OF PRECIP SHOULD FALL AS SNOW. MAIN ACCUMS WILL BE ABOVE 6K FEET...WITH SOME LOCAL TOTALS APPROACHING ONE FOOT FOR THE NORTHERN PORTIONS OF THE ZONE. 44 PREV DISCUSSION... /ISSUED 552 AM MST THU FEB 2 2012/ SHORT TERM... (TODAY THROUGH FRIDAY) .HIGH IMPACT WINTER STORM TO AFFECT PORTIONS OF SOUTHEAST COLORADO THROUGH FRIDAY... COMPLEX WINTER STORM SCENARIO EXPECTED TO PLAY OUT ACROSS SOUTHERN COLORADO THROUGH THE NEXT 36 HOURS. UPPER TROF IS ALREADY DROPPING THROUGH THE GREAT BASIN AND IS PROGGED BY MODELS TO CLOSE OFF ACROSS THE FOUR CORNERS REGION TONIGHT...THEN TRANSLATE SLOWLY TO THE NORTHEAST THROUGH SOUTHEAST COLORADO ON FRIDAY. ALTHOUGH MODELS HAVE THE LARGER SCALE FEATURES HANDLED FAIRLY WELL...THE DEVIL IS ALWAYS IN THE DETAILS. FIRST ROUND OF SNOW IS ALREADY SPREADING INTO THE WESTERN MOUNTAINS...AND IS EXPECTED TO INCREASE IN INTENSITY BY LATE MORNING AS UPPER DIFFLUENCE/STRONG UPWARD FORCING SHIFTS INTO THE AREA. LATEST MODELS ARE ALSO FASTER IN SPREADING THE PRECIPITATION EASTWARD INTO THE SOUTHEAST MOUNTAINS THIS AFTERNOON SO HAVE BUMPED UP THE START TIME FOR THE ADVISORIES FOR THE SOUTHEAST MOUNTAINS AND VALLEYS TO ACCOMMODATE. AS SURFACE CYCLOGENESIS TAKES PLACE ACROSS EASTERN NM TODAY...H7 WINDS SWING AROUND FROM THE EAST AT 20-25 KTS BY THIS EVENING...WHICH SLAMS SOME HEAVY AMOUNTS OF PRECIP INTO THE EL PASO AND PUEBLO COUNTY ACCORDING TO THE NAM...WITH 12 INCHES OF SNOW EXPECTED TO FALL BETWEEN 00Z AND 06Z ACROSS THESE AREAS! GFS WITH ITS MORE NORTHEAST H7 WINDS HAS MORE IN THE REALM OF 2 TO 5 INCHES ACROSS PORTIONS OF EL PASO...SOUTHWEST PUEBLO COUNTIES...AND THE EASTERN SLOPES OF THE WETS. MODEL SOUNDINGS SUGGEST A RAIN/SNOW SWITCH OVER WILL OCCUR ALMOST IMMEDIATELY AT KCOS...AND AROUND 8 PM OR LATER AT PUEBLO...WHICH SHOULD LIMIT ACCUMS ACROSS MOST OF PUEBLO COUNTY. GIVEN THE CONVECTIVE NATURE TO THIS INITIAL ROUND OF SNOW...AND THE POTENTIAL FOR A QUICK SEVERAL INCHES TO IMPACT THE EVENING COMMUTE ACROSS EL PASO COUNTY...HAVE OPTED TO PUT OUT A WINTER WEATHER ADVISORY OUT FOR SRN EL PASO COUNTY. SOME MELTING MAY OCCUR INITIALLY ON ROAD SURFACES...BUT SOUNDINGS COOL QUICKLY THROUGH THE EVENING...SO IF THE WINDS DO MAINTAIN AN EASTERLY COMPONENT FOR A LONGER DURATION...THEN A QUICK 3-6 INCHES IS NOT OUT OF THE QUESTION. ALREADY STARTING TO SEE THE CONVECTIVE NATURE OF THE STORM IN SAT IMAGES ACROSS WRN UT RIGHT NOW...WHICH LENDS CREDENCE TO THIS POSSIBILITY. DUE TO THE INITIAL WARMER TEMPERATURES ACROSS PUEBLO COUNTY...WILL REFRAIN FROM ANY HIGHLIGHTS AT THIS POINT. ACROSS THE REMAINDER OF THE PLAINS...SHOULD SEE A ROUND OF CONVECTION SPREAD OFF THE MOUNTAINS THIS AFTERNOON AND OUT ACROSS THE PLAINS FAIRLY QUICKLY. MODEL SOUNDINGS STILL SUGGEST A FEW HUNDRED J/KG OF CAPE ACROSS THE FAR SOUTHEAST CORNER WHERE AFTERNOON THUNDERSTORMS WILL BE POSSIBLE. SPC HAS SLIGHT RISK JUST TO THE SOUTHEAST OF THE BORDER...WITH 5 PERCENT PROB FOR HAIL CONTOUR JUST CLIPPING INTO BACA COUNTY...WHICH LOOKS VERY PLAUSIBLE GIVEN THE COOLING ALOFT WHICH WILL LOWER FREEZING LEVELS. THINK ANY HAIL WILL BE SMALL AT THIS POINT...BUT IT WILL BEAR WATCHING. FREEZING LEVELS WILL DROP OVERNIGHT ACROSS THE PLAINS WITH A RAIN/SNOW SWITCH OVER OCCURRING ACROSS KIOWA COUNTY BY AROUND 11PM-2 AM GIVEN LATEST MODEL SOUNDINGS. QUITE A BIT OF WAA/ISENTROPIC UPGLIDE SPREADING IN AS UPPER LOW CIRCULATION TIGHTENS A BIT ACROSS SE CO...SO COULD EVEN SEE A WAVERING RAIN/SNOW MIX ACROSS EASTERN PORTIONS OF KIOWA COUNTY THROUGH THE WEE MORNING HOURS. HOWEVER AS UPPER LOW PULLS EASTWARD...EXPECT NORTH WINDS TO ADVECT COLDER AIR IN...WITH A SWITCH OVER TO SNOW OCCURRING BY EARLY FRIDAY MORNING. NORTH WINDS MAY GUST TO 50 MPH ACROSS NORTHERN EL PASO...KIOWA...AND CROWLEY COUNTIES BY FRIDAY MORNING RESULTING IN THE LIKELIHOOD FOR BLIZZARD CONDITIONS ACROSS THESE AREAS...WITH THE POTENTIAL TO CAUSE SIGNIFICANT IMPACTS TO TRAVEL...PARTICULARLY ACROSS NORTHERN EL PASO COUNTY WHERE COLDER START WILL ALLOW FOR GREATER SNOW ACCUMULATIONS. AM STILL A TOUCH CONCERNED THAT TEMPERATURES HOVERING NEAR FREEZING ACROSS KIOWA COUNTY ON FRIDAY MAY RESULT IN SNOW STICKING TO SURFACES RATHER THAN BLOWING AROUND A LOT...WHICH MAY KEEP VISIBILITIES ABOVE 1/4 MILE...BUT WITH STRONG DIABATIC COOLING ASSOC WITH HEAVY PCPN...WILL LEAN TOWARDS THE CAUTIONARY SIDE AND HOIST THE BLIZZARD WARNING. STILL QUITE A BIT OF UNCERTAINTY ON HOW FAR SOUTH THE GRADIENT OF SNOWFALL WILL GET...AND SINCE THIS IS STILL A LATE 2ND PERIOD EVENT...WILL KEEP THE WINTER STORM WATCH GOING FOR PROWERS AND BENT COUNTIES...AND INCLUDE OTERO COUNTY. THIS WILL GIVE LATER SHIFTS ANOTHER SET OF MODEL RUNS TO INVESTIGATE BEFORE DECIDING. NOT TO LEAVE OUT THE SOUTHWEST/CENTRAL MTS...SNOWFALL AMOUNTS STILL LOOK TO REMAIN IN THE ADVISORY LEVELS. HAVE EXPANDED THE ADVISORIES SOME TO INCLUDE THE LOWER ELEVATIONS/EAST FACING SLOPES OF THE LA GARITAS...AND THE UPPER RIO GRANDE VALLEY...WHERE THERE MAY BE A PERIOD OF EASTERLY UPSLOPE AS H7 LOW CENTER SETS UP ALONG THE CO/NM BORDER. WITH THE CONVECTIVE NATURE TO THE EVENT AS WELL...QUICK ACCUMULATIONS OF 4 TO 8 INCHES WILL CERTAINLY BE POSSIBLE FOR THESE LOWER ELEVATIONS. WHILE CONDITIONS IMPROVE ACROSS THE WESTERN AREAS ON FRIDAY...SNOW AND BLOWING SNOW WILL CONTINUE THROUGH FRIDAY ACROSS THE SOUTHEAST PLAINS AND PIKES PEAK REGION. NORTHERLY WINDS OFF THE PALMER ERODES PCPN ACROSS SOUTHERN EL PASO AND PUEBLO COUNTIES BY FRIDAY MORNING. FOCUS FOR WRAP AROUND PCPN WILL BE ACROSS THE SOUTHEAST PLAINS...MAINLY ALONG/NORTH OF HIGHWAY 50...AND EAST OF PUEBLO AND COLORADO SPRINGS AS THE UPPER LOW STARTS TO LIFT OFF TO THE NORTHEAST. SOUNDINGS INDICATE TEMPERATURES TOMORROW MAY HOVER AROUND OR SLIGHTLY ABOVE FREEZING ALONG THE LOWER ARKANSAS RIVER VALLEY...WHICH MAY LIMIT ACCUMS TO GRASSY SURFACES. HOWEVER IF MODELS INTENSIFY THE UPPER LOW CIRCULATION (OR KEEP THE TRACK FARTHER SOUTH...THEN WARNING LEVEL SNOW ACCUMS WILL BE POSSIBLE OVER THIS AREA. WATCH WILL REMAIN OUT TO HIGHLIGHT THIS POTENTIAL FOR NOW. -KT LONG TERM... (FRIDAY NIGHT THROUGH WEDNESDAY) FRIDAY NIGHT-SATURDAY...LATEST MODELS ARE IN DECENT AGREEMENT WITH AN UPPER LOW ACROSS OVER EAST CENTRAL COLORADO FRIDAY AFTERNOON SLOWLY MOVING EAST NORTHEAST INTO WESTERN KANSAS FRIDAY NIGHT WITH A BROAD UPPER TROUGH REMAINING IN PLACE ACROSS THE CENTRAL HIGH PLAINS THROUGH THE CENTRAL ROCKIES THROUGH THE DAY SATURDAY. MOVEMENT OF THIS SYSTEM WILL GUSTY NORTHERLY WINDS AND SNOWFALL IN PLACE ACROSS THE EASTERN MTS AND PLAINS FRIDAY EVENING...WITH PRECIPITATION DIMINISHING FROM SOUTHWEST TO NORTHEAST FRIDAY NIGHT THROUGH SATURDAY MORNING. WITH THAT SAID...WILL KEEP CURRENT WARNINGS IN PLACE THROUGH FRIDAY NIGHT. COLD AIR REMAINS IN PLACE BEHIND PASSING SYSTEM KEEPING TEMPERATURES BELOW SEASONAL AVERAGES ON SATURDAY. SUNDAY-WEDNESDAY...MODELS INDICATING SOME RUN TO RUN DIFFERENCES FOR EARLY NEXT WEEK AND BEYOND. AT ANY RATE...SHOULD SEE DRIER AND WARMER CONDITIONS ACROSS THE AREA SUNDAY AND MONDAY AS SHORT WAVE RIDGING ACROSS THE DESERT SW BUILDS INTO THE ROCKIES. EASTERN PACIFIC ENERGY THEN PROGGED TO UNDERCUT RIDGE WHICH THEN MOVES ACROSS THE GREAT BASIN AND ACROSS THE ROCKIES POSSIBLY BRINGING SOME PRECIP TO THE AREA ON TUESDAY. HOWEVER...WITH THE RUN TO RUN DIFFERENCES...HAVE STAYED WITH CONSENSUS MODEL BLENDS WHICH KEEPS ANY PRECIP CONFINED TO THE HIGHER TERRAIN. -MW AVIATION... MODELS COMING INTO BETTER AGREEMENT OF SLOWER EVOLUTION OF STORM SYSTEM ACROSS THE CORNERS REGION THIS MORNING WHICH WILL MOVE ACROSS THE SOUTHERN TIER OF COLORADO THIS EVENING AND INTO EAST CENTRAL COLORADO THROUGH THE DAY ON FRIDAY. THE SLOWER MOVEMENT OF THIS SYSTEM WILL DELAY THE ONSET OF STRONG NORTHERLY FLOW ACROSS THE EASTERN PLAINS AND ALLOW FOR MODERATE TO HEAVY SNOW TO DEVELOP AT COS AND PUB LATE THIS AFTERNOON AND EVENING. FOR BOTH COS AND PUB...WILL SEE SHOWERS DEVELOPING ACROSS THE MOUNTAINS EARLY THIS AFTERNOON WITH IFR AND LIFR CONDITIONS IN SNOW AND FOG DEVELOPING AT THE TERMINALS AFT 22Z AND PERSISTING THROUGH AT LEAST 06Z WHEN GUSTY DOWNSLOPE NORTH WINDS OF 20-35KTS DEVELOP ALLOWING FOR IMPROVING CIGS AND WEATHER THERE AFTER.

MODERATE TO HEAVY SNOW WILL FALL ACROSS THE SOUTHWEST AND CENTRAL MOUNTAINS THROUGH TONIGHT...WITH THE HEAVIEST ACCUMULATIONS EXPECTED TO OCCUR THROUGH THIS EVENING. SNOW WILL SPREAD ACROSS THE SOUTHEAST MOUNTAINS THIS AFTERNOON AND CONTINUE THROUGH TONIGHT. MODERATE TO HEAVY ACCUMULATIONS CAN BE EXPECTED...WITH THE HEAVIEST AMOUNTS OF AROUND A FOOT OR MORE POSSIBLE ACROSS THE CREST OF THE SANGRES...WETS...AND PIKES PEAK AND TELLER COUNTY...WITH 5 TO 10 INCHES POSSIBLE ACROSS THE LOWER ELEVATIONS. RAIN SHOWERS WILL SPREAD ACROSS THE PLAINS THIS AFTERNOON...WITH SCATTERED THUNDERSTORMS POSSIBLE ACROSS THE FAR SOUTHEAST PLAINS THROUGH THIS EVENING. DANGEROUS CLOUD TO GROUND LIGHTNING AND SMALL HAIL UP TO 1/2 INCH IN DIAMETER WILL BE POSSIBLE WITH THE STRONGER STORMS. AS THESE RAIN SHOWERS MOVE OFF THE MOUNTAINS...THEY WILL QUICKLY CHANGE OVER TO SNOW ACROSS EL PASO COUNTY AND THE HIGHER ELEVATIONS ALONG AND WEST OF I-25. GIVEN THE CONVECTIVE NATURE TO THESE SHOWERS...LOCALLY INTENSE SNOWFALL RATES WILL BE POSSIBLE...PARTICULARLY ACROSS EL PASO COUNTY. QUICK ACCUMULATIONS OF 3 TO 6 INCHES WILL BE POSSIBLE DURING THE EVENING COMMUTE WHICH COULD CAUSE RESTRICTIONS TO VISIBILITY AND SLUSHY AND SNOW PACKED ROADS AS TEMPERATURES CONTINUE TO DROP THROUGH THE EVENING. NORTH WINDS WILL SPREAD SOUTHWARD ACROSS THE PALMER DIVIDE AND SOUTHEAST PLAINS AFTER MIDNIGHT TONIGHT. THIS WILL CAUSE WIND DRIVEN SNOW TO SPREAD ACROSS NORTHERN EL PASO COUNTY...AS WELL AS CROWLEY AND KIOWA COUNTIES...WHERE BLIZZARD CONDITIONS ARE EXPECTED TO DEVELOP AFTER MIDNIGHT. WHITE OUT CONDITIONS...WITH SIGNIFICANT IMPACTS TO TRAVEL MAY OCCUR ACROSS THESE REGION. THERE IS STILL SOME UNCERTAINTY REGARDING THE TIMING OF THE STORM INTENSIFICATION AS IT MOVES ACROSS SOUTHERN COLORADO. THE LOWER ELEVATIONS ALONG AND SOUTH OF HIGHWAY 50 AND EAST OF PUEBLO WILL SEE A RAIN SNOW MIX TONIGHT WHICH WILL CHANGE OVER TO SNOW THROUGH THE OVERNIGHT HOURS AS THE COLDER AIR MOVES IN. THIS MAY INITIALLY LIMIT SNOWFALL ACCUMULATIONS TO THE GRASSY SURFACES. HOWEVER SOME COMPUTER MODELS INDICATE THE POTENTIAL FOR THIS STORM TO INTENSIFY FURTHER WITH THE POSSIBILITY FOR HEAVY SNOW TO SPREAD FARTHER SOUTH INTO OTERO...BENT...AND PROWERS COUNTIES WHERE A WINTER STORM WATCH REMAINS IN EFFECT. PLEASE MONITOR THE LATEST FORECASTS FOR THE LATEST DETAILS ON THIS DEVELOPING WINTER STORM. .DAYS TWO THROUGH SEVEN...FRIDAY THROUGH WEDNESDAY SNOWFALL...MODERATE TO HEAVY AT TIMES...WILL BE ONGOING ACROSS MUCH OF SOUTH CENTRAL AND SOUTHEAST COLORADO FRIDAY MORNING...AS A WINTER STORM SYSTEM CONTINUES TO MOVE ACROSS THE STATE. THE EXACT TRACK OF THIS SYSTEM REMAINS UNCERTAIN AT THIS TIME WHICH COULD LEAD TO MORE OR LESS SNOWFALL THAN IS CURRENTLY EXPECTED. AT ANY RATE...THE LATEST FORECAST DATA HAS THE SYSTEM MOVING ACROSS THE SOUTHERN COLORADO AND NEW MEXICO BORDER FRIDAY MORNING WHICH THEN MOVES OUT ACROSS THE EAST CENTRAL COLORADO PLAINS FRIDAY AFTERNOON BEFORE LIFTING OUT INTO WEST CENTRAL KANSAS FRIDAY NIGHT. THE PROJECTED MOVEMENT OF THIS SYSTEM WILL BRING PERIODS OF HEAVY WIND DRIVEN SNOWFALL TO PORTIONS OF THE EASTERN PLAINS...GENERALLY ALONG AND NORTH OF HIGHWAY 50...WHERE SIGNIFICANT ACCUMULATIONS IN EXCESS OF 6 INCHES WILL BE POSSIBLE. IN ADDITION TO THE SNOW...STRONG NORTH WINDS GUSTING TO 50 MPH AT TIMES...WILL CAUSE AREAS OF POOR VISIBILITIES IN BLOWING AND DRIFTING SNOW...ESPECIALLY ACROSS THE SOUTHEAST PLAINS. THIS WILL LIKELY CAUSE SIGNIFICANT TRAVEL IMPACTS ACROSS MUCH OF EASTERN COLORADO ON FRIDAY. GRADUALLY IMPROVING CONDITIONS ARE EXPECTED FRIDAY NIGHT THROUGH SATURDAY AS THE STORM SYSTEM SLOWLY PULLS AWAY FROM THE AREA. .SPOTTER INFORMATION STATEMENT... WEATHER CONDITIONS THAT MEET REPORTING CRITERIA FOR SPOTTERS WILL BE LIKELY ACROSS MUCH OF SOUTH CENTRAL AND SOUTHEAST COLORADO TODAY AND TONIGHT. 31/23
