AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE PUEBLO CO 242 PM MST THU FEB 1 2007 .SHORT TERM... (TONIGHT AND FRIDAY) SHORT TERM CONCERNS INCLUDE SNOW AND BLOWING SNOW POTENTIAL FOR THE I-25 CORRIDOR AND ADJACENT MOUNTAINS ALONG WITH COLD TEMPERATURES AND WIND CHILLS ACROSS THE REST OF THE REGION. CURRENT WATER VAPOR IMAGERY CONTINUES TO INDICATE A BROAD UPPER TROUGH ACROSS THE UPPER GREAT LAKES REGION THROUGH THE ROCKIES AND INTO THE GREAT BASIN REGION WITH MODERATE NORTHWEST FLOW PERSISTING ALOFT ACROSS THE STATE. WATER VAPOR ALSO INDICATING YET ANOTHER STRONG SHORT WAVE SYSTEM AND 100+ KT JET CORE DIVING ACROSS THE NORTHERN GREAT BASIN ATTM. LATEST MSAS AND SFC PLOTS INDICATING LEADING EDGE OF ARCTIC FRONT MOVING ACROSS THE NORTHEAST PLAINS AND TO THE PALMER DVD ATTM WITH 2-4MB 3HRLY PRESSURE RISES BEING REALIZED ACROSS EASTERN WYOMING ATTM. MODELS REMAIN IN GOOD AGREEMENT ON DETAILS AND HAVE MADE ONLY MINOR TWEAKS TO CURRENT FORECAST AS EMBEDDED SHORT WAVE ACROSS THE NORTHERN GREAT BASIN MOVES ACROSS THE STATE OVERNIGHT PROVIDING SYNOPTIC LIFT ACROSS THE AREA. STRONG FRONTOGENETICAL FORCING IS ALSO PROGGED AT THE SURFACE...WITH H7-SFC WINDS REMAIN PROGGED TO BECOME MORE EAST TO NORTHEAST AS THE ARCTIC FRONT CONTINUES TO MOVE ACROSS THE REST OF THE PLAINS THIS AFTERNOON. MODEL SOUNDING CONTINUE TO SHOW IDEAL DENDRITIC GROWTH POTENTIAL WITH TEMPS WITHIN THE MOISTURE LAYER PROGGED BETWEEN -14C AND -20C. WITH ALL THAT SAID...SHOULD SEE SNOW CONTINUING TO DEVELOP ACROSS THE AREA LATE THIS AFTERNOON THROUGH THE OVERNIGHT AND HAVE KEPT CURRENT HIGHLIGHT IN PLACE. ACCUMULATIONS BETWEEN 3 AND 6 INCHES ACROSS THE UPPER ARKANSAS RIVER VALLEY AND I-25 CORRIDOR...4 TO 8 INCHES ACROSS THE CENTRAL MTS AND 5 TO 10 INCHES EASTERN MTS...AND WITH SNOW RATIOS APPROACHING 30:1 COULD SEE LOCALLY HIGHER AMOUNTS OF POWDER. SNOW TO TAPER OFF FROM WEST TO EAST WITH PASSAGE OF TROUGH AXIS FRIDAY MORNING AND HAVE TAPERED POPS TO MATCH...WITH BEST POPS REMAINING ACROSS THE CENTRAL MTS WITH CONTINUED MODERATE OROGRAPHIC FLOWS PERSISTING. LATEST MODELS A TAD FURTHER EAST WITH CENTER OF SFC HIGH PRESSURE AND COLDEST TEMPERATURES...THOUGH WITH H7 AND H85 TEMPS RANGING BETWEEN -16C TO -22C AND -8C TO -14C RESPECTIVELY ACROSS THE STATE...HAVE KEPT TEMPERATURES AOB THE COLDEST GUIDANCE. HAVE OPTED NOT TO ISSUE A WIND CHILL ADVISORY ACROSS THE PLAINS ATTM AND LET THE FORECAST TALK FOR ITSELF WITH -10F TO -18F WIND CHILLS TOMORROW MORNING. -MW .LONG TERM... (FRIDAY NIGHT THROUGH THURSDAY) COLD NW FLOW WL BE FOUND OVR THE AREA FRI NIGHT. WITH A FAIRLY STRONG GRADIENT OVR THE AREA...WINDS OVR THE MTS AND HIGH VALLEY WL BE BREEZY TO WINDY AND OVER NIGHT WIND CHILL TEMPS ARE A CONCERN. IF THE WIND FORECAST IS ON TRACK OR IF THE WINDS END UP BEING STRONGER...WIND CHILL HIGHLIGHTS MAY BE NEEDED IN SOME AREAS...BUT WL NOT MAKE THAT DECISION AT THIS TIME. SOME MSTR IN THE NW FLOW OVR THE CENTRAL MTS...MAY LEAD TO SOME LIGHT SNOW SHOWERS. ON SATURDAY THE STRONG NW FLOW CONTINUES OVR THE AREA AS DOES THE CHANCE FOR SNOW OVR MAINLY THE CENTRAL MTS. H7 TEMPS WARM UP FASTER IN THE GFS THAN ON THE NAM FOR SAT. THE GFS HAS TEMPS OF -3 TO -8C...WHILE THE NAM HAS -11 TO -18C. BUT THE LOW LEVEL COLD AIR SHOULD STILL BE A PROBLEMS AND SO TEMPS ARE A CHALLENGE. IT IS HARD TO SAY HOW MUCH THE TEMPS WL WARM AND SO WL STILL KEEP MAX TEMPS BELOW ALL GUIDANCE. THE GRADIENT ALOFT DECREASES SOME FOR SAT NIGHT AND SUN AND THE CHANCE FOR LIGHT SNOW SHOWERS WL PROBABLY CONTINUE IN THE CENTRAL MTS. H7 TEMPS SUN ARE FORECAST TO BE -4 TO -8 ON THE NAM AND -3 TO +3C ON THE GFS. ONCE AGAIN THE TEMPS WL BE A CHALLENGE. MEX GUIDANCE FOR SUN IS GENERALLY IN THE 40S TO LOWER 50S FOR THE SERN PLAINS...BUT IT IS STILL A CHALLENGE TO DECIDE WHEN THE LOW LEVEL COLD AIR MASS WL RECEDE. FEEL THAT KEEPING THE TEMPS COLD IS THE WAY TO GO AND IT LOOKS LIKE SURROUNDING WFO/S ARE THINKING THE SAME THING...SO WL STAY WITH TEMPS THAT ARE WELL BELOW GUIDANCE. NOT MUCH CHANGE FOR SUN NIGHT AND MON...BUT WITH TEMPS ALOFT WARMING A LITTLE MORE AND A CHANCE THAT THE LOW LEVEL COLD AIR WL BE RECEDING...WILL START HAVE WARMER MAX TEMPS IN THE FORECAST...BUT AGAIN IT IS A CHALLENGE TO KNOW HOW MUCH TO WARM THEM. WL KEEP TEMPS BELOW GUIDANCE FOR THE FAR ERN AREAS. FOR TUE THRU WED AN UPR RIDGE MOVES OVR THE GREAT BASIN AND WE SHOULD WARM UP A LITTLE MORE AND THE WEA SHOULD BE DRY. THE 06Z RUN OF THE DGEX HAD AN UPR TROF EXTENDING FROM A LOW OFF THE PACIFIC NW INTO WRN NV AT 12Z THU. THE 12Z RUN OF THE GFS HAS A CLOSED LOW SITTING OFF THE CENTRAL CA COAST...WHILE THE 12Z RUN OF THE ECMWF WAS MORE SIMILAR TO THE DGEX. THE DGEX THEN MOVED THE TROF INTO UT WITH MSTR AND PCPN MOVING INTO WRN PORTIONS OF THE FORECAST AREA DURING THE DAY THU. THE GFS KEEPS A CLOSED LOW JUST OFF THE CA COAST THRU THU AND LEAVES A RIDGE OVR THE FORECAST AREA AND GENERALLY DRY WEA. && .PUB WATCHES/WARNINGS/ADVISORIES...
