NWS Pueblo, CO wrote its last area forecast discussion before the first event at Dec 27, 4:46 AM MST, 3 hours 14 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE PUEBLO CO 446 AM MST THU DEC 27 2007 .SHORT TERM... ...WINTER STORM TO AFFECT MOST OF SOUTHEAST COLORADO TODAY... WELL ADVERTISED STORM IS NOW MOVING INTO THE FOUR CORNERS REGION AND WILL TRACK THROUGH NORTHERN NM TODAY. TREND OVER THE PAST 24 H HAS BEEN TO TRACK THE LOW SLIGHTLY FURTHER SOUTH...AS AN INTENSE SUBTROPICAL JET STREAK BLASTS THROUGH SOUTHERN NM AND INTO THE SRN TX PANHANDLE THIS AFTERNOON. THIS SLIGHT SHIFT IN TRACK...ALONG WITH ASSOCIATED SLOWER MOVEMENT...WILL RESULT IN A LITTLE BETTER SHOT AT SIGNIFICANT SNOWFALL FOR THE SRN I-25 CORRIDOR...AND A SLIGHTLY REDUCED THREAT OF HEAVY SNOW FOR TELLER COUNTY AND THE PALMER DIVIDE. PARTICULARLY STRIKING IS THE EXTENT MODEL FORECASTS OF H7 WINDS HAVE BACKED OFF ON THE STRONG NORTHERLIES ORIGINALLY EXPECTED FOR THE PALMER LATER THIS AFTERNOON. WHAT WAS 50+ KNOTS NOW LOOKS MORE LIKE 25 KTS IN MODEL GUIDANCE...ALTHOUGH GIVEN THE OVERALL STRENGTH OF THE SYSTEM THIS IS PROBABLY A LITTLE UNDERDONE. SO...BLIZZARD CONDITIONS FOR THE PALMER LOOK LESS LIKELY WITH LATEST GUIDANCE. WITH WEAKENED H7 FLOW STAYING MORE EASTERLY FOR A LONGER PERIOD OF TIME...THIS WILL BRING A LITTLE BETTER CHANCE AT SOME ACCUMULATING SNOW TO KPUB AND POINTS SOUTH AND EAST. MAIN CONCERN HAS SHIFTED TO THE FAR EASTERN PLAINS...ESPECIALLY EASTERN KIOWA...ALTHOUGH HEAVY BANDED SNOW WILL BE POSSIBLE PRETTY MUCH ANYWHERE E OF I-25 THIS AFTERNOON. THERE WILL BE POTENTIAL FOR 8+ INCH ACCUMS WITH THESE MESOSCALE BANDS BY EARLY THIS EVE. WIND GUSTS IN THE 40 KT RANGE WILL ALSO BE POSSIBLE AND CREATE TREACHEROUS CONDITIONS OVER THE PLAINS AT TIMES. EASTERN MTS...PARTICULARLY THE WETS AND CUCHARA REGION...SHOULD ALSO DO FAIRLY WELL WITH THIS EVENT. STORM WILL WRAP UP AND INTENSIFY EARLY THIS EVE AS IT MOVES E OF THE REGION. TROWEL ACTION WILL KEEP THINGS GOING OVR THE FAR ERN PLAINS THRU THIS EVE. PREVIOUS (EVE) SHIFT DID AN EXCELLENT JOB AT MANAGING THE COMPLEX MIX OF WINTER HEADLINES GOING THRU THIS EVE...SO ONLY HAD TO MAKE MINOR ADJUSTMENTS TO AMTS AND TIMING OF THE WARNINGS AND ADVISORIES IN EFFECT. AS CORE OF -32 DEGREE H5 LOW MOVES THRU TONIGHT...CONVECTIVE ACTIVITY WILL CONTINUE...BUT GRADUALLY WIND DOWN OVERNIGHT. COULD SEE SOME CLEARING FROM W TO E OVERNIGHT...WHICH WILL ONCE AGAIN LEAD TO SOME VERY COLD CONDITIONS BY FRI MORNING. ROSE .LONG TERM... (FRIDAY THROUGH WEDNESDAY) TREND TOWARDS WARMER AND WINDIER CONDITIONS EXPECTED BY LATE IN THE WEEKEND...WITH THE POTENTIAL FOR ANOTHER COLD SNAP EARLY NEXT WEEK. ANOTHER MUCH WEAKER SYSTEM MOVES ACROSS THE AREA FRIDAY AS A SHORTWAVE DROPS DOWN FROM THE PACIFIC NORTHWEST. THIS SHOULD KEEP SOME SNOW SHOWERS CONTINUING ALONG THE CONTINENTAL DIVIDE THROUGH THE DAY...WHILE THE REMAINDER OF SOUTH CEN/SE COLORADO REMAINS DRY. MAIN CHALLENGE THIS DAY WILL BE MAX TEMPS. GIVEN A FRESH SNOW COVER...AND LACK OF STRONG WINDS IN THE LOW LEVELS ACROSS THE PLAINS AND HIGH VALLEYS...HAVE GONE ON THE COOLER SIDE OF GUIDANCE VALUES...AND EVEN UNDERCUT GUIDANCE IN THE SAN LUIS VALLEY WHERE STRONG INVERSIONS ARE NOT LIKELY TO BREAK. SFC LEE TROF DEVELOPS SAT NIGHT AS FLOW ALOFT INCREASES AHEAD OF 140+ KT UPPER JET WHICH DROPS INTO THE GREAT BASIN BY SAT. MIN TEMPS FRI NIGHT WILL BE TRICKY ALONG THE LOWER EASTERN SLOPES...WHERE TEMPS MAY ACTUALLY START TO WARM OVERNIGHT. STRONGER WINDS WILL MIX DOWN INTO THE LOWER ELEVATIONS BY LATE SAT AFTN AS ANOTHER EMBEDDED SHORTWAVE CROSSES THE MTS AND LEE TROF KICKS EASTWARD IN RESPONSE. H7 TEMPS NOT ALL THAT MUCH WARMER THOUGH...SO EVEN WITH MORE WIND...SATURDAY WILL STILL BE A COLD DAY WITH GENERALLY UPPER 20S/LOWER 30S ACROSS THE PLAINS...AND TEENS AND 20S ACROSS THE MTS/HIGH VALLEYS...AND SINGLE DIGITS ABOVE TIMBERLINE. HIGHER MTN SNOWS EXPECTED TO RAMP UP AGAIN FOR SAT/SAT NIGHT AS THE NOSE OF UPPER JET MOVES ACROSS THE STATE. FOR NOW DOESN/T APPEAR SNOWFALL AMOUNTS WILL BE ABOVE ADVISORY CRITERIA. MAIN CONCERN THOUGH WILL BE WIND POTENTIAL ACROSS THE EASTERN SLOPES OF THE SE MTNS AND ADJACENT PLAINS. IF PARAMETERS COME TOGETHER...WE COULD SEE A HIGH WIND EVENT SHAPING UP...PREDOMINANTLY AROUND THE NORTHERN RAMPART RANGE WHERE WNW FLOW PROVIDES THE BEST ORTHOGONAL COMPONENT TO THE MTN BARRIER. FOR NOW...MTN TOP STABLE LAYER IS NOT TERRIBLY STRONG...AND THERE COULD BE TOO MUCH FORWARD SHEAR ALOFT TO ALLOW FOR BREAKING WAVES...BUT SCENARIO WILL BE MONITORED CLOSELY. SUNDAY APPEARS TO BE THE WARMEST DAY OF THE WEEK...THEN NEXT COLD FRONT DROPS IN FOR SUN NIGHT...COOLING US OFF FOR MONDAY. MUCH COLDER AIR DROPS INTO THE CENTRAL PLAINS/UPPER MID WEST MONDAY NIGHT/TUESDAY WITH SOME QUESTION AS TO HOW FAR WEST THIS COLD AIR MASS WILL AFFECT. ECMWF SUGGESTS TUES COULD BE SIGNIFICANTLY COOLER THAN CURRENT SET OF GRIDS PORTRAYS...BUT GIVEN THE UNCERTAINTIES WILL HOLD THE COURSE FOR NOW. UPPER RIDGE BRINGS ANOTHER WARMING TREND BY MID WEEK. -KT && .AVIATION... WIDESPREAD IFR TO VLIFR CONDITIONS CAN BE EXPECTED OVR ALL OF THE FORECAST AREA TODAY INTO EARLY THIS EVE. GRADUAL CLEARING FROM W TO E CAN BE EXPECTED TONIGHT. MAY SEE SOME LOCALIZED FZFG AGAIN BY FRI MORNING IN THE VALLEYS. && .PUB WATCHES/WARNINGS/ADVISORIES...
