AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE PUEBLO CO 848 AM MST SAT NOV 10 2012 .UPDATE... AS PER HI RES DATA...DEWPOINTS WILL LIKELY CRASH INTO THE SINGLE DIGITS LATER THIS MORNING. STRONG WINDS COMBINED WITH THE LOW RH VALUES WILL CAUSE THE REGION TO GO INTO RED FLAG CRITERIA. AS PER COORD WITH SPC...RED FLAG WARNINGS HAVE BEEN ISSUED FOR THE PLAINS. KLHX IS ALREADY GUSTING TO 49 KNTS THIS MORNING AND WINDS WILL LIKELY REACH MARGINAL WARNING CRITIRIA THROUGH EARLY AFTERNOON ACROSS THE EASTERN PLAINS. WINDS SHOULD REMAIN BELOW WARNING CRITERIA IN EL PASO AND THE POPULATED REGIONS OF PUEBLO COUNTY. \/HODANISH && .PREV DISCUSSION... /ISSUED 409 AM MST SAT NOV 10 2012/ SHORT TERM... (TODAY AND TONIGHT) CURRENTLY...THE UPPER LOW PRES TROUGH WAS SLOWLY MOVING ACROSS THE GREAT BASIN THIS MORNING...WITH A 120 KT CORE UPPER JET CARVING OUT THE SOUTHERN END OF THE TROUGH AND NOSING INTO THE SW QUAD OF COLORADO. IR SATELLITE IMAGERY INDICATED A HEALTHY BAND OF ENHANCEMENT LAYING ACROSS THE WESTERN HALF OF THE STATE...WITH ONGOING SNOW BEING REPORTED OVER MUCH OF THE HIGHER TERRAIN OF THE CONTDVD. SPORADIC GUSTY W-SW WINDS HAVE BEEN REPORTED AS WELL IN THE LEE OF THE E MTS...WITH SOME OF THE AFA SENSORS REPORTING GUSTS TO 55 MPH AT TIMES EARLIER. WINDS HAVE SEEMED TO DECOUPLE FOR MOST AREAS AS OF 330 AM...BUT TEMPS HAVE REMAINED SOMEWHAT MILD WITH MOST OF THE EASTERN LOCATIONS REPORTING TEMPS IN THE UPPER 40S TO MID 50S. TODAY AND TONIGHT...THE UPPER TROUGH CONTINUES TO SLIDE SLOWLY TO THE EAST OVER THE NEXT 24 HRS...CROSSING THE ROCKY MT REGION THROUGH SUNDAY MORNING. MUCH OF THE SNOWFALL WILL BE RESTRICTED TO THE HIGHER TERRAIN...ESPECIALLY OVER THE CENTRAL AND SW MTS WHERE HIGHLIGHTS ARE IN PLACE AND ADDITIONAL ACCUMULATIONS OF ANYWHERE FROM 6 TO 16 INCHES ARE POSSIBLE. ONE THING TO NOTE...AS THE TROUGH MOVES TO THE EAST...INITIAL FAVORED AREAS OF SNOWFALL ALONG THE CONTDVD WILL SHIFT TO THE NORTH...AND BY THIS EVENING THE BEST AREA FOR ADDITIONAL SIGNIFICANT SNOWFALL WILL BE THE CENT MTS. AMOUNTS OVER THE E MTS ARE EXPECTED TO BE MUCH LESS...AND ANY PCPN OVER THE LOWER ELEVATIONS OF THE E PLAINS WILL BE PALTRY AT BEST. H7 TEMP CHARTS INDICATE THAT MUCH COOLER AIR WILL BE FILTERING IN FROM THE WEST TODAY...AND THE MAX TEMPS FOR MUCH OF THE CWA WILL PROBABLY BE REALIZED BY MIDDAY...EVEN WITH THE STRONG WINDS THAT DEVELOP. MODELS HAVE BEEN IN PRETTY GOOD AGREEMENT ON DROPPING A SFC COLD FRONT SOUTH ACROSS THE PALMER DVD RIGHT AROUND 06Z...THEN PUSHING IT TO THE SOUTH AND WEST OVERNIGHT. ANOTHER CONCERN WILL BE THE HIGH WIND POTENTIAL. BOTH GFS AND NAM MODELS ARE INDICATING H7 WINDS RANGING FROM 45 TO 60 KTS MOVING ACROSS THE SOUTHERN TIER AND SE CORNER FROM 12Z-21Z. IT PROMISES TO BE A WINDY DAY TODAY...BUT OPTED TO MAINTAIN ONGOING WIND GRIDS THAT PAINT SUSTAINED 30 MPH WITH GUSTS OF 50 TO 55 MPH. 27 LONG TERM... (SUNDAY THROUGH FRIDAY) EARLY SUN MORNING A FRONT WL BE MOVING SOUTH THRU THE SERN CO PLAINS. PCPN CHANCES NOT LOOKING VERY PROMISING FOR THE SERN PLAINS ON SUN. THE NAM KEEPS THE SOUTHEAST PLAINS MAINLY DRY IN THE MORNING...WITH MAYBE JUST A FEW SPOTTY SHOWERS IN THE WAKE OF THE FRONT...AND THEN IN THE AFTERNOON SHOWS A LITTLE BETTER CHANCE FOR SOME PCPN OVR EL PASO AND KIOWA COUNTIES. WHILE THE GFS HAS A LITTLE BETTER POTENTIAL FOR SOME PCPN OVR THE PLAINS...AND IN THE AFTERNOON MAINLY FOCUSES PCPN CHANCES OVR EL PASO COUNTY. WL PROBABLY ALSO HAVE THE CHANCE FOR SOME LIGHT SNOW OVR THE SANGRE DE CRISTO AND WET MTNS. THE W TO NW FLOW OVR THE AREA...COMBINED WITH MSTR OVR THE CENTRAL CO MTNS WL LIKELY LEAD TO SOME ADDITIONAL...GENERALLY LIGHT ACCUMULATIONS OVR LAKE COUNTY AND THE HIGHER ELEVATIONS OF CHAFFEE COUNTY THRU THE DAY. OVR THE SW MTS...THE MSTR WL BE LESS FAVORABLE BUT WL PROBABLY CONTINUE TO SEE AT LEAST SOME SCT SNOW SHOWERS DURING THE DAY. HIGHS ON SUN WL BE MUCH COLDER THAN TODAY OVR THE SERN PLAINS BY 20 TO NEARLY 30 DEGREES...AND BY 10-15 DEGREES IN THE SAN LUIS VALLEY AND UPR ARKANSAS RIVER VALLEY. DRIER AIR WL MOVE OVR THE AREA SUN NIGHT AS THE UPR TROF MOVES FARTHER EAST. THERE WL PROBABLY STILL BE SOME LIGHT SNOW SHOWERS OVR THE CENTRAL CO MTS THRU THE FIRST PART OF THE NIGHT...BUT SHOULD END BY LATE NIGHT. WITH CLOUDS DECREASING OVR THE AREA SUN NIGHT AND A COOL AIR MASS IN PLACE...OVERNIGHT LOW TEMPS WL BE QUITE COLD. THE SERN PLAINS SHOULD SEE LOWS OF ABOUT 9-16 DEGREES... WHILE OTHER AREAS SHOULD HAVE LOWS IN THE SINGLE DIGITS ABOVE AND BELOW ZERO. DRY WEST TO NW FLOW ALOFT WL BE OVR THE AREA ON MON...WITH WARMER TEMPS. HIGHS OVR MOST OF THE SOUTHEAST PLAINS SHOULD BE AROUND 50 OR IN THE LOWER 50S WHICH IS STILL BELOW NORMAL BY 5-10 DEGREES. THE SAN LUIS VALLEY SHOULD SEE READINGS NR 40...WHICH IS AROUND 10 DEGREES BELOW NORMAL. LATE MON NIGHT/EARLY TUE MORNING A WEAK SHORTWAVE TROF IS EXPECTED TO MOVE ACRS THE AREA WHICH COULD LEAD TO SOME WESTERLY BREEZES...ESPECIALLY OVR AND NR THE MTS WHICH COULD KEEP OVERNIGHT LOWS A BIT MILD IN THOSE AREAS. DRY WESTERLY FLOW WL CONTINUE FOR TUE AND WED ACRS THE AREA...WITH HIGH TEMPS BY WED BEING AROUND NORMAL. THERE ARE STILL SOME TIMING DIFFERENCES WITH THE NEXT SYSTEM EXPECTED TO AFFECT THE AREA LATE THIS COMING WEEK. THE GFS CONTINUES TO SHOW AN UPR TROF MOVING INTO UT AND AZ ON THU WHICH THEN MOVES OVR CO THU NIGHT AND EARLY FRI...BRINGING PCPN TO THE MTNS AND SOME OF THE LOWER ELEVATIONS. HOWEVER THE ECMWF IS STILL SLOWER WITH THIS SYSTEM AND KEEPS THE AREA DRY THU...THEN MOVES THE UPR TROF INTO CO FRI AFTERNOON...SPREADING PCPN CHANCES ACRS THE AREA. AVIATION... MAIN CONCERNS THROUGH THE FORECAST PERIOD REMAIN SNOW OVER THE HIGHER TERRAIN...AND STRONG WINDS. KALS...BRISK S-SW WINDS WILL CONTINUE THROUGH MUCH OF THE DAY TODAY...WITH GUSTS NEAR 40 KTS POSSIBLE THIS AFTN. SCATTERED SNOW SHOWERS MAY SPILL OVER FROM THE SURROUNDING MTS THROUGH THE DAY...CREATING TEMPORARY MVFR TO IFR CONDITIONS THROUGH THE AFTN. THIS EVENING SHOWER ACTIVITY WILL BECOME MORE ISOLATED...THEN WILL MOST LIKELY SHUT OFF AFTER 06Z. KCOS AND KPUB...STRONG WIND GUSTS IN EXCESS OF 35 KTS ARE POSSIBLE THROUGH THE AFTERNOON. SHOWER ACTIVITY IS EXPECTED TO REMAIN TIED TO THE MTS DIRECTLY TO THE WEST.
