AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE CHEYENNE WY 320 AM MST TUE FEB 25 2014 .SHORT TERM...(TODAY THROUGH THURSDAY NIGHT) ISSUED AT 300 AM MST TUE FEB 25 2014 SOUTHEAST WYOMING AND THE NEBRASKA PANHANDLE WILL REMAIN THE BATTLE GROUND BETWEEN MILD AIR OUT OF THE SOUTHWEST CONUS AND COLD CANADIAN AIR INTO THE FORESEEABLE FUTURE. AFTER LIFTING SLIGHTLY NORTHWARD OVERNIGHT THE FRONTAL BOUNDARY WILL MAKE A REINFORCING PUSH SOUTH TODAY. THE FRONT WILL BE CO-LOCATED AND PARALLEL WITH AN UPPER LEVEL JET WHICH WILL PROVIDE EXTRA LIFT TO AID IN THE PRODUCTION OF SNOW. ALSO LOOKING AT UPSLOPE FLOW ALONG AND EAST OF THE LARAMIE RANGE TO ENHANCE SNOW POTENTIAL. A QUICK MOVING CLIPPER CURRENTLY OVER FAR SOUTHERN ALBERTA WILL ALSO GET INTO THE ACT AND WILL RIDE OVER THE BOUNDARY THIS AFTERNOON. ALL THESE FACTOR WILL COME TOGETHER TO PRODUCE A QUICK SHOT OF SNOW TODAY. SNOW IS CURRENTLY FALLING UPSTREAM OVER SOUTHERN MONTANA AND FAR NORTH-CENTRAL WYOMING. THIS SNOW WILL SPREAD SOUTHEAST INTO EAST- CENTRAL WYOMING AND FAR NORTHERN PORTIONS OF THE NEBRASKA PANHANDLE TOWARDS SUNRISE. ALREADY STARTING TO SEE COOLING CLOUD TOPS IN NORTHEAST WYOMING. THE FRONT WILL QUICKLY SHIFT SOUTH THIS MORNING...REACHING THE COLORADO BORDER AROUND NOON MST. SNOW WILL QUICKLY DEVELOP ALONG THE FRONT WITH GENERALLY A 4 TO 6 HOUR PERIOD OF SNOW FOLLOWING FROPA. SNOW AMOUNTS WILL BE ON THE LIGHT SIDE AS THERE WILL NOT BE A LOT OF TIME TO ACCUMULATE AND NO INSTABILITY TO BE CONCERNED WITH TODAY...SO NO CONVECTIVE SNOW EXPECTED EXCEPT POSSIBLY A BRIEF PERIOD NEAR THE SNOWY AND SIERRA MADRE RANGES THIS AFTERNOON. CONTEMPLATED A SNOW ADVISORY FOR A FEW ZONES...MAINLY BETWEEN ARLINGTON TO CHEYENNE WHERE SLIGHTLY HIGHER AMOUNTS OF SNOW ARE EXPECTED BUT MOST OF THIS AREA SHOULD SEE SNOW ACCUMULATIONS BELOW ADVISORY THRESHOLDS. GENERALLY LOOKING FOR QUICK INCH OR TWO INCHES OF SNOW TODAY BUT NOT MUCH MORE. WITH A DECENT PERIOD OF UPSLOPE FLOW AND UPPER LEVEL JET IN PLACE...CHEYENNE SHOULD SEE ONE OF THE HIGHER SNOW AMOUNTS OUTSIDE THE MOUNTAINS WITH UPWARDS OF 3 INCHES POSSIBLE. SNOW WILL END ACROSS THE NORTHERN CWA LATE THIS MORNING WITH SNOW ENDING NEAR THE COLORADO BORDER EARLY THIS EVENING. TURNING DRY TONIGHT THROUGH TOMORROW NIGHT WITH THE MAIN CHANCE FOR PRECIPITATION OVER THE SNOWY AND SIERRA MADRE RANGES AS WESTERLY UPSLOPE FLOW WILL BE IN PLACE. ANY SNOW ACCUMULATION IN THE MOUNTAINS WILL BE MINIMAL. TEMPERATURE FORECAST WILL BE TRICKY WEDNESDAY AND THURSDAY FOR AREAS EAST OF THE LARAMIE RANGE. TEMPERATURES WILL BE LARGELY BE DEPENDENT ON THE LOCATION OF THE FRONTAL BOUNDARY. SHOULD SEE A DECENT PUSH OF WARM AIR EASTWARD WEDNESDAY BUT TOUGH TO SAY HOW EAST THE WARM AIR WILL MIX AND MODELS NOT IN GREAT AGREEMENT. FOR THURSDAY A LEE TROUGH DEVELOPS...PULLING THE LOW LEVEL COLD AIR BACK TO THE WEST. WILL LIKELY SEE VERY LARGE DIFFERENCES IN HIGH TEMPERATURES THURSDAY OVER A VERY SHORT DIFFERENCE DEPENDENT ON POSITION OF THE FRONT. CHEYENNE COULD EASILY SEE A HIGH IN THE 50S WITH TORRINGTON STRUGGLING TO REACH FREEZING BUT TOUGH TO PINPOINT THE FRONTAL POSITION AT THIS TIME. .LONG TERM...(FRIDAY THROUGH MONDAY) ISSUED AT 300 AM MST TUE FEB 25 2014 NEXT SURGE OF COLDER AIR WILL BEGIN TO FILTER OVER MUCH OF THE CWA FRIDAY WITH THE SFC FRONT LIKELY BANKING UP AGAINST THE MTNS AND STAYING THERE THROUGH THE WEEKEND BEFORE POSSIBLY RETREATING BACK EAST MONDAY. MAIN CONCERN WILL BE SHORTWAVE ENERGY THAT WILL EJECT ENE ACROSS THE REGION FROM A SOUTHERN STREAM UPPER TROF SATURDAY WITH NORTHERN AND SOUTHERN STREAM ENERGY PHASING SATURDAY NIGHT AND SUNDAY AS IT MOVES ACROSS THE REGION. THIS WILL OVERRIDE LOW LEVEL UPSLOPE FLOW AND PRODUCE A FAVORABLE ENVIRONMENT FOR POTENTIALLY DECENT SNOWFALL ACROSS AT LEAST PARTS OF THE CWA FRIDAY NIGHT AND SATURDAY BEFORE TAPERING OFF. WILL HAVE TO WATCH CLOSELY TO SEE HOW THIS DEVELOPS. OTHERWISE AFTER A RELATIVELY MILD DAY FRIDAY ITS BACK TO QUITE COLD CONDITIONS SATURDAY AND SUNDAY ESPECIALLY OVER THE PLAINS...LIKELY INTO MONDAY AS WELL. && .AVIATION...(FOR THE 12Z TAFS THROUGH 12Z WEDNESDAY MORNING) ISSUED AT 300 AM MST TUE FEB 25 2014 MAINLY VFR OVER THE AREA THIS MORNING THEN CONDITIONS WILL DETERIORATE TO MVFR/IFR CIGS AND VSBYS LATER THIS MORNING THROUGH THE AFTERNOON AS AN UPPER LEVEL DISTURBANCE NEARS THE REGION.
