AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE GLASGOW MT 920 AM MST TUE NOV 18 2003 .SHORT TERM...NO UPDATE PLANNED. TODAY SIMILAR TO YESTERDAY WITH TEMPERATURE SPREAD ACROSS CWA DEPENDENT ON SNOW COVER. FLAT UPPER RIDGE MOVING ACROSS MONTANA BRINGING STRONG WINDS ACROSS THE DIVIDE. LEE TROF OVER CENTRAL MONTANA WITH SHALLOW INVERSION IN PLACE OVER EASTERN MONTANA. WINDS ABOVE THE INVERSION 35-40KT ON MORNING SOUNDING BUT WARM AIR ADVECTION...LOW LEVEL LIFT AND LOW LAPSE RATE WILL MAKE WINDS DIFFICULT TO MIX DOWN. ANY MIXING WILL BE SHORT LIVED LATE THIS AFTERNOON AND STRONGEST OVER THE SOUTHWEST ZONES. MADE SOME MINOR ADJUSTMENTS TO GRIDS BUT NOT ENOUGH TO CHANGE ZFP. EBERT TODAY THRU THU... COOLING ALOFT WITH YESTERDAYS UPPER TROUGH BROUGHT BETTER MIXING...RESULTING IN ABOVE FREEZING TEMPERATURES ALL AREAS. THIS GNAWED AT EDGES OF SNOWCOVER...BUT DEEPER SNOWCOVER STILL SOLID OVER ROUGHLY NE HALF OF CWA. ALBEDO LOWERING WITH TIME...BUT SIGNIFICANT IMPACT TO CONTINUE. WILL KEEP THESE AREAS AROUND THE 39F MARK FOR HIGHS TODAY. A WARM FRONT IS TO BRING AN INCREASE IN MID CLOUDS TODAY...BUT MOST LIFT AND MOISTURE REMAINING TO OUR NORTH. MAV HAS SLIGHT POPS INDICATED...BUT WILL CONTINUE WITH DRY FORECAST PER ETA. BUILDING UPPER RIDGE PUSHES IN FROM THE WEST THIS AFTERNOON AND TONIGHT WITH ASSOCIATED STRONG NVA. 850 MB WINDS TODAY FORECAST UP TO 55KT...UP TO 120KT AT JET LEVEL...BUT SURFACE GRADIENTS NOT GREAT...NOTHING TO MIX THESE SPEEDS DOWN...LAPSE RATES A LITTLE LESS FAVORABLE THAN YESTERDAY. WILL AGAIN HAVE STRONGEST WINDS OVER BARE GROUND S-SW...LEAST WINDS N-NE. WEDNESDAY SIMILAR IN WIND REGARD...WITH JUST ENOUGH MIXING REACHING LOWER LEVELS FOR SOME WARMING...BUT NOT FULL POTENTIAL. MUCH OF SOUTHERN HALF OF CWA TO REACH ABOUT 60. RIDGE SOMEWHAT DIRTY WEDNESDAY WITH MOISTURE SEEN ENTERING IT OVER THE PACIFIC. A STRONG AND COLD UPPER TROUGH DIGGING SE FROM THE GULF OF ALASKA LOWERS HEIGHTS WED AFTERNOON AND WED NIGHT WITH A STRONG COLD FRONT PASSAGE LATE. MODELS HAVE FLIPPED-FLOPPED PAST RUNS WITH TIMING ON THIS WHEN IT WAS IN THE LONG RANGE...BUT AT LEAST THEY ARE IN GOOD AGREEMENT NOW. MUCH COOLER BEHIND THE FRONT AND HAVE LOWERED ONGOING HIGHS A LOT. MODELS DONT SHOW MUCH MOISTURE WITH THE FRONT WHICH LOOKS REASONABLE...BUT WILL ADD 20 POPS DUE TO TO FRONTS STRENGTH. THESE FRONTS ARE TYPICALLY INITIALLY DRY DUE TO FORMATION OF A WAVE ON IT AS IT BECOME PARALLEL TO UPPER FLOW...AND WHICH WILL THREATEN NE MT WITH MORE SIGNIFICANT PRECIP IN EXTENDED PERIOD. SIMONSEN .LONG TERM... COMPLEX FORECAST FOR PERIOD...HENCE CONFIDENCE REMAINS LOW. A DEEP UPPER TROUGH EXPECTED TO DIG IN PACIFIC NORTHWEST/SOUTHWEST CANADA WHICH GRADUALLY DRAGS COLD SOUTH OVER REGION...AND MAKES SLOW EASTWARD PROGRESS. MODELS IN REASONABLE AGREEMENT WITH EVOLUTION OF PATTERN...BUT GFS IS FASTEST WITH EASTWARD MOVEMENT...WHICH SEEMS UNREASONABLE GIVEN EXPECTED AMPLITUDE OF SYSTEM AND STRENGTH OF COLD AIR. HAVE BASED TIMING MAINLY ON ECMWF AND CANADIAN MODELS BUT WITH SOME INPUT FROM GFS. TREND TOWARD COLDER TEMPERATURES CONTINUES... HAVE LOWERED TEMPERATURES FURTHER WITH EXPECTATION LEADING EDGE OF ARCTIC AIRMASS WILL ARRIVE BY BEGINNING OF PERIOD...THENCE GRADUALLY REINFORCED. EXPECT OVERRUNNING SNOW TO BEGIN THURSDAY NIGHT WEST... THEN OVERSPREAD CWA FRIDAY. ALL MODELS SPIN UP MAJOR CYCLONE OVER CENTRAL ROCKIES WHICH PROGRESSES INTO NORTHERN PLAINS...BUT DIFFER WITH PATH. THIS DIFFERENCE PRIMARY CHALLENGE OF FORECAST...WITH POTENTIAL FOR MORE SNOW OVER SOUTHEAST AND EASTERN ZONES IF THIS SYSTEM PASSES CLOSER THAN CURRENTLY EXPECTED. WILL CONTINUE CONSERVATIVE FORECAST PHILOSOPHY FOR NOW...BUT HAVE INTRODUCED LINGERING SNOW SHOWERS EASTERN ZONES SATURDAY NIGHT AND SUNDAY... GRADUALLY ENDING FROM WEST TO EAST. WINDS COULD BE A FACTOR WITH THIS SYSTEM SATURDAY INTO SUNDAY...ESPECIALLY WITH FRESH SNOWCOVER ...AND HAVE KEPT EASTERN ZONES WINDIER...BUT STRONG WINDS COULD REMAIN EAST OF CWA. CLEARING FROM WEST TO EAST SUNDAY AND MONDAY COULD RESULT IN EVEN COLDER TEMPERATURES THAN FORECAST...ESPECIALLY MINIMA WITH NEW SNOW...BUT AGAIN CONSERVATIVE UNTIL DETAILS OF EVENT BECOME MORE EVIDENT. && .GGW WATCHES/WARNINGS/ADVISORIES...NONE &&
