.DISCUSSION...

TONIGHT THROUGH WEDNESDAY...A VIGOROUS SHORTWAVE TROUGH...CURRENTLY
DROPPING SE ALONG THE BC COAST WILL CONTINUE SOUTHEAST INTO THE
NORTHERN ROCKIES AND ACROSS THE STATE ON TUESDAY...BRINING A
SIGNIFICANT PATTERN CHANGE TO THE REGION. FIST IMPACT WILL BE STRONG
WINDS...WHICH HAVE ALREADY DEVELOPED ALONG THE ROCKY MTN FRONT AND
WILL BE SPREADING EAST ONTO THE PLAINS TONIGHT AS THE UPPER LEVEL
SYSTEM NEARS THE REGION. MOISTURE WILL INCREASE AS THE SYSTEM NEARS
AND TEMPS ALOFT COOL OVERNIGHT WITH SNOW INCREASING OVER AREAS
ALONG THE CONTINENTAL DIVIDE OVERNIGHT...HOWEVER DOWNSLOPE WINDS
WILL KEEP MOST OF THE PLAINS DRY THROUGH TONIGHT. MAIN ENERGY
ASSOCIATED WITH THE TROUGH WILL MOVE ACROSS THE REGION TUESDAY
MORNING WITH A COLD FRONT AT THE SURFACE DROPPING SOUTH THROUGH
NORTH CENTRAL MT...USHERING IN A MUCH COOLER AIRMASS. DYNAMICS
ASSOCIATED WITH THE UPPER LEVEL SYSTEM AND NW UPSLOPE FLOW BEHIND THE
FRONT WILL BRING A PERIOD OF SNOW TO MUCH OF NORTH CENTRAL MT TUESDAY
MORNING WITH LIGHT UPSLOPE SNOWS CONTINUING ON THE NORTH SLOPES OF
THE CENTRAL MT MTNS INTO TUESDAY EVENING. WINTER STORM WARNING FOR
THE ROCKY MTN FRONT AND ADJACENT PLAINS WILL REMAIN INTACT TO
HIGHLIGHT WIND THREAT TONIGHT AND SNOW/BLOWING SNOW POTENTIAL ON
TUESDAY. FARTHER EAST WINTER STORM WATCH WILL BE CONVERTED TO A HIGH
WIND WARNING TO HIGHLIGHT WINDS TONIGHT AND SNOW AND BLOWING SNOW
ADVISORY FOR THE REMAINDER OF NORTH-CENTRAL MT. SNOW AND WINDS WILL
DIMINISH TUESDAY NIGHT AS THE SYSTEM PULLS AWAY FROM THE REGION.
DRYING CONTINUES THROUGH WEDNESDAY AS A RIDGE OF HIGH PRESSURE MOVES
OVER THE REGION. TEMPERATURES WILL REMAIN MILD UNDER WINDY AND
CLOUDY CONDITIONS BEFORE THE FRONT MOVES THROUGH BRINGING COOLING
TUESDAY MORNING. THIS WILL MAKE TEMPERATURES TRICKY WITH TONIGHTS
LOW AND TOMORROWS HIGH LIKELY OCCURRING SIMULTANEOUSLY EARLY TUESDAY
MORNING WITH TEMPS COOLING THROUGH THE DAY. SOMEWHAT BELOW AVERAGE
TEMPERATURES WILL REMAIN OVER THE REGION TUESDAY NIGHT THROUGH
WEDNESDAY. HOENISCH

WEDNESDAY NIGHT THROUGH SATURDAY NIGHT...MEDIUM RANGE MODELS
CONTINUE TO PORTRAY THIS PERIOD AS UNSETTLED. A STRONG UPPER RIDGE
WILL REMAIN ANCHORED ALONG THE WEST COAST WITH STRONG NORTHWEST FLOW
ALOFT OVER THE COUNTY WARNING AREA. THIS WILL RESULT IN PERIODS OF
LIGHT SNOW WEDNESDAY NIGHT AND THURSDAY..WITH THE HEAVIEST AMOUNTS
FALLING IN THE MOUNTAINS. A BRIEF RESPITE FROM THE SNOW OCCURS
FRIDAY AS A LITTLE DRIER AIR MOVES OVER THE AREA. A STRONGER UPPER
TROF WILL SLIDE OVER THE AREA LATE SATURDAY/SATURDAY NIGHT BRINGING
ANOTHER ROUND OF SCATTERED SNOW. TEMPERATURES WILL BE NEAR OR
SLIGHTLY ABOVE SEASONAL AVERAGES.

SUNDAY THROUGH MONDAY...MODELS START OUT IN FAIR AGREEMENT BEFORE
DIVERGING ON MONDAY. HOWEVER...RUN TO RUN INCONSISTENCIES FURTHER
DETRACT FROM FORECAST CONFIDENCE. LATEST RUN NOT AS COLD ON BOTH GFS
AND ECMWF. BOTH MODELS INDICATE AN ARCTIC FRONT PLUNGING SOUTH
ACROSS THE FORECAST AREA SUNDAY. DUE TO UNCERTAINTY AT THIS POINT I
WENT WITH MAINLY CHANCE POPS OF SNOW SPREADING ACROSS THE
AREA...BUT THE POTENTIAL IS THERE FOR MORE WIDESPREAD SNOW.
TEMPERATURES WILL STILL DROP DRAMATICALLY...AND COMBINED WITH
GUSTY NORTHERLY SURFACE WINDS BEHIND THE FRONT...BITTER COLD WIND
CHILLS CAN BE EXPECTED. EK

.AVIATION...
UPDATED 1720Z.
AN UPPER LEVEL RIDGE OVER THE REGION TODAY WILL QUICKLY BE PUSHED

BECOME INCREASINGLY STRONG AND GUSTY THROUGH THE NEXT 24 HOURS.
CLOUDS WILL INCREASE THROUGH THE AFTERNOON WITH SNOW SPREADING FROM
WEST TO EAST AFTER 06Z. VFR CONDITIONS WILL PREVAIL THROUGH
06Z...THEN EXPECT PREVAILING MVFR AND LOCAL IFR CONDITIONS AS
CEILINGS LOWER AND VISIBILITY IS RESTRICTED BY SNOW AND BLOWING
SNOW. THOMSON
