NWS Pueblo, CO wrote its last area forecast discussion before the first event at Dec 30, 4:34 AM MST, 6 hours 26 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE PUEBLO CO 434 AM MST SUN DEC 30 2007 .SHORT TERM... (TODAY AND TONIGHT) ...FORECAST CONCERNS FOR TODAY AND TONIGHT WILL BE HIGH WIND POTENTIAL FOR THE EASTERN MOUNTAINS ABOVE 11000 FEET...AND LOWER EASTERN SLOPES OF PIKES PEAK AND THE RAMPART RANGE...AND SNOW AMOUNTS ALONG WITH BLOWING SNOW FOR THE CENTRAL MOUNTAINS... WELL DEFINED LEE TROF IN PLACE THIS MORNING...THOUGH WIND GUSTS HAVE BEEN SLOW TO MATERIALIZE ALONG THE LOWER EASTERN SLOPES OF THE RAMPARTS AND PIKES PEAK. HAVE SEEN SOME WIND GUSTS UP TO 33 KTS AT THE HIGHER ELEVATION SENSOR OF THE AIR FORCE ACADEMY EARLIER THIS MORNING. A QUICK LOOK AT MODEL SOUNDINGS FROM 00Z AND 06Z NAM12 SUGGESTS THERE IS STILL TOO MUCH FORWARD SHEAR FOR MOUNTAIN WAVE DEVELOPMENT THIS MORNING. UPPER JET EXTENDS ACROSS MUCH OF THE WESTERN U.S. AND CENTRAL AND NRN U.S. ROCKIES. NEXT SPEED MAX IS STILL ON TRACK TO MOVE ACROSS THE STATE TONIGHT AS JET STREAM SAGS SOUTHWARD. BY AFTERNOON H7 WINDS OVER THE EASTERN MTS INCREASE TO 60-70KTS...WITH H5 WINDS OF AROUND 70-80 KTS. MODEL X-SECTIONS THROUGH THE PIKES PEAK AREA SHOW POTENTIAL TEMPERATURE SURFACES BEGIN TO DIP DOWN ALONG THE LEE SIDE OF THE MOUNTAINS AFTER 18Z...AS WINDS ALOFT BECOME A BIT MORE LAMINAR. THUS...THERE IS STILL THE POTENTIAL FOR SOME DAMAGING WIND GUSTS TO MATERIALIZE ACROSS EASTERN TELLER AND WESTERN EL PASO COUNTY. FOR THIS REASON WILL LET THE HIGH WIND WARNING RIDE...AND MENTION THIS TIME FRAME IN THE NPW. FOR THE HIGHER ELEVATIONS...WIND SHOULD INCREASE FROM NORTH TO SOUTH DURING THE DAY WITH THE CREST OF THE MOUNTAINS SEEING SUSTAINED WINDS OF 50 MPH WITH GUSTS TO 75 MPH. THUS...WILL KEEP THE OTHER WARNINGS GOING...AND HOIST A HIGH WIND WARNING FOR THE SOUTHERN SANGRE DE CRISTO MOUNTAINS ABOVE 11000 FEET AFTER 18Z. ELSEWHERE WEST OF I-25 WILL ALSO EXPERIENCE VERY WINDY CONDITIONS WHICH SHOULD STAY JUST BELOW HIGH WIND CRITERIA. ANOTHER CONCERN THIS BRINGS IS AREAS OF BLOWING SNOW OVER THE FRESH SNOW PACK. THIS COULD CAUSE ROAD WAYS TO BECOME SLICK...ESPECIALLY ALONG NORTH SOUTH ORIENTED ROADWAYS. HAVE PUT BLOWING SNOW IN WX GRIDS...AND WILL MENTION IN THE HWO AS WELL. FOR THE CENTRAL MOUNTAINS...WINDS AT MYP SENSOR HAVE BEEN GUSTING OVER 50 KTS THROUGH THE NIGHT WITH POOR VISIBILITIES IN SNOW AND BLOWING SNOW. AREA RADARS NOT PICKING UP MUCH IN THE WAY OF ECHOES...SO HUNCH IS ITS PROBABLY MORE BLOWING SNOW THAN FALLING SNOW. REGARDLESS...VISIBILITIES WILL BE NEAR WHITE OUT CONDITIONS THROUGH THE DAY...AND MOISTURE AND LIFT WILL INCREASE THIS AFTERNOON AS NEXT JET STREAK APPROACHES. THUS...SNOW SHOULD INCREASE ACROSS THE CENTRAL MOUNTAINS LATE THIS AFTERNOON THROUGH TONIGHT. ANOTHER 2 TO 8 INCHES COULD FALL IN THESE AREAS...AND WILL EXTEND THE SNOW AND BLOWING SNOW ADVISORY THROUGH 12Z. AS THE UPPER JET MOVES ACROSS TONIGHT...COULD SEE SOME SNOW BANDS DEVELOP ACROSS THE ADJACENT EASTERN PLAINS AS ARCTIC COLD FRONT DROPS SOUTHWARD. GRIDS ALREADY HAVE POPS PRETTY WELL HANDLED WITH THIS. COULD BE SPOTTY AMOUNTS OF .5 TO 1 INCH OF SNOW UNDER THE SNOW BAND...BUT IT SHOULD BE MOVING SOUTHWARD AT A MODERATE CLIP WHICH SHOULD LIMIT SNOW TOTALS. MIN TEMPS TONIGHT WILL BE A CHALLENGE AS VERY COLD AIR MOVES IN. WINDS APPEAR TO HELP KEEP THE PLAINS MIXED MOST OF THE NIGHT WHICH SHOULD PREVENT TEMPS FROM DROPPING INTO THE SINGLE DIGITS. -KT .LONG TERM... (MONDAY THROUGH SATURDAY) ...VERY COLD TEMPERATURES LIKELY MONDAY NIGHT/TUESDAY MORNING... MONDAY...VERY COLD TEMPERATURES AND A VIGOROUS UPPER LEVEL JET STREAM WILL BE DIRECTLY OVER THE CENTRAL ROCKIES. IT WOULD BE A RATHER /RAW/ DAY WITH AIR TEMPERATURES IN THE SINGLE DIGITS IN THE MOUNTAINS AND HIGH VALLEYS TO 20S/NEAR 30 SOUTHEAST CO. 700MB TEMPERATURES ARE PROGGED TO BE -14C TO -18C OVER MUCH OF CO. SURFACE AIR TEMPERATURES COMBINED WITH THE WIND COULD PRODUCE APPARENT TEMPERATURE/WIND CHILL READINGS OF 30 BELOW ZERO TO ZERO IN THE MOUNTAINS/HIGH VALLEYS TO SINGLE DIGITS-TEENS ACROSS SOUTHEAST CO PLAINS MONDAY. GIVEN 700MB WINDS OF 25-45KTS...IT COULD BE A RATHER BRISK-WINDY DAY...ESPECIALLY IN THE AFTERNOON. ANY CHANCE FOR PRECIPITATION WOULD BE SOME LIGHT SNOW AROUND THE SOUTHWEST/CENTRAL MOUNTAINS AROUND THE CONTINENTAL DIVIDE. MONDAY NIGHT AND TUESDAY...VERY COLD TO EXTREMELY COLD TEMPERATURES WILL BE LIKELY MONDAY NIGHT AND TUESDAY MORNING. NAM-WRF AND GFS HAVE BEEN VERY CONSISTENT IN SETTLING A 1050-1055MB HIGH ACROSS CO MONDAY NIGHT AND DRIFTING IT EASTWARD INTO THE EASTERN CO/WESTERN KS PLAINS TUESDAY AFTERNOON. NOT LOOKING FOR A LOT OF CLOUD COVER GIVEN THE VERY COLD AND RELATIVELY DRY AIR ALOFT. HOW COLD WILL IT GET. A LOT OF IT DEPENDS ON THE SURFACE WIND DECOUPLING...ESPECIALLY FOR THE LOW LYING VALLEYS. THE WIND MAY HAVE A TENDENCY TO STAY UP A LITTLE MORE ACROSS THE SOUTHEAST CO PLAINS GIVEN A LITTLE MORE WIND ALOFT AND A TIGHTER PRESSURE GRADIENT. GIVEN THE FLOW...HAVING A LITTLE TROUBLE BELIEVING THE MIDLEVEL TEMPERATURES WILL WARM DURING THE NIGHT. MUCH OF THE AREA WILL LIKELY SEE SUB-ZERO SURFACE TEMPERATURES...ESPECIALLY THE HIGH MOUNTAIN VALLEYS. I HAVE ALAMOSA GOING TO -35F MONDAY NIGHT/TUESDAY EARLY MORNING...BUT IT COULD BE -45F IF IT SETS UP JUST RIGHT. THE ALL-TIME RECORD LOW TEMPERATURE IS -50F/28 JANUARY 1948. CONCEPTUALLY...THIS PATTERN IS CLOSE TO THAT RECORD DAY...HOWEVER IT HAS TO SET UP PERFECTLY. MANY OF THE HIGH MOUNTAIN VALLEYS SHOULD BE -10F TO -25F DURING THE NIGHT. APPARENT TEMPERATURE/WIND CHILL READINGS COULD REACH -20F TO -45F ACROSS THE MOUNTAINS/HIGH VALLEYS MONDAY NIGHT/ TUESDAY EARLY MORNING APPROACHING WARNING/ADVISORY CRITERIA. THIS IS NEW YEARS EVE AND NEW YEARS DAY...SO FOLKS COULD BE OUT IN THE VERY COLD TO EXTREMELY COLD TEMPERATURES. TOO EARLY FOR A WATCH...SO WILL HIT THE POTENTIAL HIGH IMPACT EVENT IN THE HAZARDOUS WEATHER OUTLOOK AND A CR NEWS OF THE DAY STORY. TUESDAY/S HIGH TEMPERATURES WILL BE A HUGE CHALLENGE GIVEN THE WARMING ALOFT DURING THE DAY IN RESPONSE TO WEST-NORTHWESTERLY FLOW DEVELOPING. GIVEN THE VERY COLD TEMPERATURE START...LOW SUN ANGLE...SNOWPACK...AND EXTREME STRONG INVERSION...TEMPERATURES WILL LIKELY STRUGGLE TO GET INTO THE SINGLE DIGITS ACROSS THE SAN LUIS VALLEY CENTER FLOOR. MOS APPEARS TO BE WAY TOO WARM. WEDNESDAY AND THURSDAY...MIDDLE AND UPPER LEVEL FLOW BACKS TO A WEST-SOUTHWESTERLY CHINOOK FLOW AND WOULD PROJECT WARMING TEMPERATURES ACROSS MUCH OF CO...MAYBE OR MAYBE NOT FOR ALAMOSA IT ALL DEPENDS IF THE WIND PICKS UP. LITTLE OR NO CHANCE FOR PRECIPITATION. FRIDAY AND SATURDAY...NO CHANGES TO THESE FORECAST PERIODS. POTENTIAL FOR A FEW WEAK WEATHER SYSTEMS TO MOVE THROUGH THE CENTRAL ROCKIES. METZE && .AVIATION... LLWS WILL BE POSSIBLE NEAR THE KCOS AIRPORT THROUGH THE DAY AS UPPER LEVEL JET MOVES ACROSS THE STATE...AND LEE TROF STAYS PINNED UP ALONG THE EASTERN SLOPES OF THE SE MTS. BY LATE AFTERNOON THROUGH THE EVENING...WESTERLY WINDS SHOULD SPREAD INTO THE KCOS AND KPUB SITES. OTHERWISE...VFR CONDITIONS EXPECTED THROUGH THE DAY. AS JET MOVES ACROSS SOME ISOLATED LIGHT SNOW WILL DEVELOP UNDER MVFR-VFR CIGS EAST OF THE MOUNTAINS. MOUNTAIN PEAKS TODAY WILL SEE WESTERLY WINDS OF 30 TO 50 MPH WITH GUSTS UP TO 60-75 MPH. AREAS OF SNOW AND BLOWING SNOW CAN BE EXPECTED OVER THE FRESH SNOW PACK. CENTRAL MOUNTAINS WILL CONTINUE TO SEE PERIODS OF SNOW AND BLOWING SNOW WITH LIFR CONDITIONS OVER THE MOUNTAINS. -KT && .PUB WATCHES/WARNINGS/ADVISORIES...

THIS HAZARDOUS WEATHER OUTLOOK IS FOR PORTIONS OF CENTRAL...EAST CENTRAL...SOUTH CENTRAL AND SOUTHEAST COLORADO. .DAY ONE...TODAY AND TONIGHT SNOW AND BLOWING SNOW WILL CONTINUE ACROSS LAKE COUNTY AND THE HIGHER ELEVATIONS OF THE SAWATCH AND MOSQUITO RANGES OF CHAFFEE COUNTY ABOVE 10000 FEET. TOTAL SNOWFALL ACCUMULATIONS OF 4 TO 10 INCHES WILL BE POSSIBLE...WITH WEST TO NORTHWEST WINDS OF 30 TO 40 MPH WITH GUSTS UP TO 65 MPH CAUSING EXTENSIVE BLOWING AND DRIFTING SNOW. WHITE OUT CONDITIONS CAN BE EXPECTED AT TIMES OVER THE MOUNTAIN PASSES SUCH AS MONARCH...FREMONT...AND TENNESSEE PASS. THE EASTERN MOUNTAINS WILL SEE VERY WINDY CONDITIONS TODAY WITH SUSTAINED WINDS OF 30 TO 50 MPH WITH GUSTS UP TO 75 MPH CAN BE EXPECTED ACROSS THE HIGHER ELEVATIONS OF THE SANGRE DE CRISTO...WET MOUNTAINS...AND PIKES PEAK. A FEW DAMAGING WIND GUSTS MAY DESCEND THE EASTERN SLOPES OF PIKES PEAK AND THE RAMPART RANGE INTO WESTERN EL PASO COUNTY TODAY THROUGH THIS EVENING. THE TIME FRAME THIS IS MOST LIKELY TO OCCUR WILL BE DURING THE AFTERNOON AS THE JET STREAM MOVES IN OVERHEAD. ACROSS THE LOWER ELEVATIONS OF THE MOUNTAINS...IT WILL STILL BE WINDY WITH WESTERLY WIND GUSTS UP TO 50 TO 65 MPH POSSIBLE. THESE WINDS MAY CAUSE AREAS OF BLOWING SNOW OVER THE FRESH SNOW PACK. BLOWING SNOW CAN CAUSE ROADWAYS TO BECOME SLICK AGAIN...AND CAN REDUCE VISIBILITIES TO BELOW 1 MILE AT TIMES. ISOLATED TO SCATTERED SNOW SHOWERS WILL SPREAD EASTWARD TONIGHT ACROSS THE EASTERN MOUNTAINS AND ADJACENT PLAINS. LOCAL ACCUMULATIONS OF UP TO 1 INCH WILL BE POSSIBLE UNDER DEVELOPING SNOW BANDS. .DAYS TWO THROUGH SEVEN...MONDAY THROUGH SATURDAY VERY COLD TO EXTREMELY COLD TEMPERATURES WILL BE POSSIBLE NEW YEARS EVE AND DAY. LOW TEMPERATURES ARE FORECAST TO BE 10 TO 35 BELOW ZERO ACROSS THE MOUNTAINS AND HIGH VALLEYS...AND 5 BELOW TO 5 ABOVE ZERO ALONG THE INTERSTATE 25 CORRIDOR AND EASTWARD NEW YEARS DAY MORNING. LOWEST WIND CHILL READINGS COULD BE 20 TO 40 BELOW ZERO ACROSS THE MOUNTAINS AND HIGH VALLEYS...AND 5 TO 20 BELOW ZERO ALONG THE INTERSTATE 25 CORRIDOR AND EASTWARD THROUGH NEW YEARS EVE INTO NEW YEAR DAY MORNING. WIND CHILL READINGS OF 20 TO 40 BELOW ZERO CAN LEAD TO FROSTBITE IN 11 TO 30 MINUTES WHEN SKIN IS EXPOSED. PEOPLE PLANNING OUTDOOR ACTIVITIES DURING NEW YEARS EVE SHOULD DRESS APPROPRIATELY. AGENCIES ASSISTING PEOPLE STRANDED OUTDOORS SHOULD MAKE PREPARATIONS FOR THE POTENTIAL OF EXTREMELY COLD TEMPERATURES NEW YEARS EVE AND DAY. ALSO...PETS SHOULD BE BROUGHT INDOORS. VERY COLD NIGHTTIME TEMPERATURES WILL PERSIST IN THE SAN LUIS VALLEY THROUGH AT LEAST FRIDAY. THERE IS THE POTENTIAL FOR ANOTHER INCH OF ACCUMULATING SNOW ACROSS THE CONTINENTAL DIVIDE MONDAY MORNING. THE NEXT CHANCE FOR MINOR ACCUMULATING SNOW WILL BE ACROSS THE SOUTHWEST AND CENTRAL MOUNTAINS AROUND THE CONTINENTAL DIVIDE THURSDAY NIGHT THROUGH SATURDAY. .SPOTTER INFORMATION STATEMENT... WEATHER CONDITIONS THAT MEET REPORTING CRITERIA FOR SPOTTERS WILL BE POSSIBLE ACROSS THE SOUTHWEST AND CENTRAL MOUNTAINS FOR SNOW AND BLOWING SNOW...AND ACROSS TELLER AND EL PASO COUNTIES AND THE HIGHER ELEVATIONS OF THE SANGRE DE CRISTO AND WET MOUNTAINS FOR HIGH WINDS...TODAY AND TONIGHT.
