MODELS ARE FAIRLY SIMILAR FOR THIS PART OF THE FORECAST AND HAVE GOOD RUN TO RUN CONSISTENCY. THE LARGE RIDGE ALOFT OVER THE EASTERN PACIFIC EARLY THIS MORNING WILL CONTINUE TO BUILD AND MOVE SLOWLY EAST THROUGH 00Z TUESDAY. A SHORTWAVE TROUGH IS CURRENTLY MOVING OVER THE TOP OF THE RIDGE IN THE GULF OF ALASKA AND WILL MOVE OVER THE NORTHERN PLAINS LATE TONIGHT AND MONDAY. THE CLIPPER SYSTEM WILL MOVE THE ASSOCIATED SURFACE LOW FROM WEST CENTRAL ALBERTA AT 12Z TODAY TO THE EASTERN DAKOTAS 12Z MONDAY. A SHALLOW CANADIAN POLAR FRONT WILL BACK INTO AT LEAST THE EAST PART OF THE CWA LATE TONIGHT AND MONDAY MORNING. AT THIS TIME IT APPEARS THAT THERE WILL BE ENOUGH MOISTURE...JET DYNAMICS AND MID LEVEL FRONTOGENESIS TO PRODUCE A PERIOD OF LIGHT SNOW MAINLY OVER AND EAST OF THE LARAMIE RANGE LATE TONIGHT AND MONDAY MORNING. THE LIGHT SNOW WILL LINGER THROUGH THE AFTERNOON HOURS ALONG THE LARAMIE RANGE. SURFACE HIGH PRESSURE BUILDS INTO THE HIGH PLAINS AND WILL IMPROVE CONDITIONS OVER THE REST OF THE EAST PART OF THE CWA MONDAY AFTERNOON.

THE NORTHWEST FLOW ALOFT WILL CONTINUE TO PRODUCE OROGRAPHIC SNOW OVER THE SNOWY RANGE THROUGH MONDAY...WITH SEVERAL INCHES OF ACCUMULATING SNOW LIKELY. OTHERWISE...THE MAIN ISSUE FOR THIS PART OF THE FORECAST WILL STILL BE THE WINDS. CURRENTLY KARL IS GUSTING TO 50 MPH WITH THE LOWEST GATES OF THE MEDICINE BOW PROFILER AT 45 KNOTS. THE LOW LEVEL HEIGHT DIFFERENCES BETWEEN KCAG AND KCPR REMAIN MARGINAL THROUGH TONIGHT AND SO WILL KEEP WINDS JUST BELOW CRITERIA DURING THAT TIME. THE STRONGER WINDS WILL SHIFT OVER THE EAST PART OF THE CWA BY MONDAY AS THE FLOW ALOFT BECOMES MORE NORTHERLY AND THE 300 MB JET IS OVER THE AREA. WIND HIGHLIGHTS MAY BE NEEDED OVER THE EAST PART OF THE CWA BY MONDAY. FOR NOW HAVE GUSTS BETWEEN 45 AND 50 MPH AND A WIND ADVISORY MIGHT NEED TO BE CONSIDERED FOR THE PANHANDLE. TEMPERATURES TODAY AND TONIGHT WILL REMAIN ABOVE NORMAL WITH COOLER TEMPERATURES IN MOST AREAS FOR MONDAY. LONG TERM...MONDAY NIGHT THROUGH SATURDAY MAINLY DRY CONDITIONS WILL PREVAIL ACROSS THE CWA THROUGH THE EXTENDED PERIOD. THE ONLY EXCEPTION BEING A CHANCE OF SNOW ACROSS THE NORTHERN ZONES AND THE MOUNTAINS TUES NIGHT AND WED. NW FLOW WILL DOMINATE THE PERIOD WITH A HIGH AMPLITUDE RIDGE OFF THE WEST COAST AND A DEEP UPPER TROUGH OVER THE EASTERN HALF OF THE U.S. A COLD FRONT IN ASSOCIATION WITH A DISTURBANCE WILL MOVE ACROSS THE AREA TUES NIGHT AND WED. WARMER TEMPERATURES WILL OCCUR FOR FRI AND SAT AS THE FRONTAL BOUNDARY MOVES TO THE EAST AND A SURFACE LEE TROUGH SETS UP. WINDY CONDITIONS WILL ALSO OCCUR THROUGHOUT THE EXTENDED PERIOD. A DISTURBANCE WILL POSSIBLY MOVE ACROSS THE FORECAST AREA ON SAT...BUT THE TRACK OF THE FEATURE REMAINS UNCERTAIN AT THIS TIME. HIGH TEMPERATURES WILL BE AROUND 10 DEGREES ABOVE NORMAL ON TUES...COOLING TO AROUND NORMAL FOR WED AND THUR...AND 7 TO 10 DEGREES ABOVE NORMAL FOR FRI AND SAT. AVIATION...WEST WINDS WILL GUST AS HIGH AS 45 KNOTS OVER AND NEAR THE SNOWY AND LARAMIE RANGES AGAIN TODAY AND TONIGHT. THE SURFACE WINDS WILL SHIFT TO THE NORTHWEST LATE TONIGHT AND MONDAY WITH GUSTS TO 40 KNOTS LIKELY EAST OF THE LARAMIE RANGE. VFR CONDITIONS OVER THE CWA WILL LOWER TO MVFR CEILINGS AND VISIBILITIES IN LIGHT SNOW FOR A PERIOD LATE TONIGHT AND MONDAY. THOSE CONDITIONS WILL PERSIST INTO MONDAY AFTERNOON OVER KLAR...KCYS AND KEAN. && .CYS WATCHES/WARNINGS/ADVISORIES... WY...HIGH WIND WARNING UNTIL 4 PM SUNDAY FOR WYZ062. NE...NONE. &&
