AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE CHEYENNE WY 226 PM MST WED MAR 30 2005 .SHORT TERM...COMPLEX FORECAST IN THE OFFING. 18Z NAM SUITE RADICALLY INCREASED ITS QPF AND BULLSEYED THE WESTERN NE PANHANDLE. GFS HAD THIS ALL ALONG SO IT WAS NOT A LEAP TO BUY INTO IT. PRETTY SURE ITS NOT CONVECTIVE FEEDBACK SINCE NO INSTABILITY IS NOTED. OMEGA FIELD IS VERY STRONG SO...FROM DYNAMIC CLASS...IT IS EITHER DIFF VORT ADV OR THICKNESS ADVECTION. MODELS PROG BOTH..SO IT SEEMS TO BE A CLASSIC SYNOPTIC EVENT REFRESHINGLY INDEPENDENT OF UPSLOPE CONSIDERATIONS. BIGGEST CLUE IS THAT A THETA-E RIDGE IS APPARENT BOTH ON MSAS AND EVENING MODEL PROGS. SOME NEB FORECAST POINTS HAVE NAM QPF/S COMING IN AT GREATER THAN 3/4 INCH. QUESTION WILL BE CRITICAL THICKNESSES. APPEARS SIGNIFICANT MELTING WILL TAKE PLACE WITH THE GROUND BEING SO WARM. MODEL SNOW TOTALS ARE A HEAD-TURNING 12 TO 15 INCHES BUT THINK THAT 3 TO 5 IS PRUDENT NUMBER AT THIS TIME. ELSEWHERE...CONVECTION IS BREAKING OUT ALL QUADS. LIGHTNING STRIKES OCCURRING NEAR STATION. INSTABILITY SHOULD SLOWLY SUBSIDE AFTER SUNSET BUT KEPT ISOLATED T IN GRIDS INTO THE EVENING. .LONG TERM...FOR MUCH OF THIS PORTION OF THE FORECAST MILD AND DRY WEATHER WILL BE OVER THE CWA. A RIDGE ALOFT BUILDS OVER THE ROCKIES FRIDAY AND THEN IS FLATTENED FRIDAY NIGHT AND SATURDAY AS A SHORTWAVE TROUGH MOVES ACROSS SOUTHERN CANADA. A COLD FRONT IS PUSHED THROUGH AT LEAST THE NORTHEAST PART OF THE CWA SATURDAY MORNING. THE GFS AND CANADIAN MODELS BOTH PAINT AN AREA OF LIGHT QPF OVER SOUTHEAST WYOMING SATURDAY AFTERNOON AND EVENING. THE FLOW ALOFT BECOMES MORE SOUTHWESTERLY SUNDAY AND MONDAY IN ADVANCE OF A SIGNIFICANT SHORTWAVE TROUGH. THAT FEATURE ALONG WITH ITS SURFACE REFLECTION SHOULD PRODUCE SHOWERS AND SOME THUNDERSTORMS MONDAY AFTERNOON...WITH SHOWERS BECOMING SNOW EARLY MONDAY NIGHT AND LINGERING INTO TUESDAY MORNING. HIGHS FOR TUESDAY WILL BE BELOW GUIDANCE VALUES. THAT STORM SYSTEM IS FAIRLY SIMILAR TO THAT OF TODAY AND TONIGHT OVER THE ROCKIES. AFTER THAT SYSTEM MOVES EAST...HEIGHTS ALOFT RISE WITH A RIDGE AXIS BACK OVER THE ROCKIES FOR NEXT WEDNESDAY WITH A RETURN TO MILD AND DRY WEATHER. && .CYS WATCHES/WARNINGS/ADVISORIES...
