AREA FORECAST DISCUSSION...CORRECTED FOR TIME
NATIONAL WEATHER SERVICE GREAT FALLS MT
1123 AM MST MON NOV 23 2015

...UPDATE TO AVIATION...

.DISCUSSION...

A BAND OF LIGHT SNOW FLURRIES APPEARED ON RADAR BUT DID NOT HAVE
ANY REPORTS OF SNOWFALL AT THE SURFACE. THIS BAND WAS ASSOCIATED
WITH A WEAK SURFACE TROUGH AND EXITING THE AREA INTO NORTHEAST
MONTANA. SKIES REMAINED MOSTLY CLOUDY OVER NORTH CENTRAL MONTANA
AND MOSTLY SUNNY FOR SOUTHWEST. FRESHENED TEMPERATURES TO MATCH
OBSERVED TRENDS...BUT OTHERWISE THE FORECAST REMAINS IN GOOD
SHAPE. PN

&&

.AVIATION...
UPDATED 1823Z.
THE TAF PERIOD STARTS OUT QUIET BUT CONDITIONS WILL GRADUALLY BEGIN
TO DETERIORATE FROM NORTH TO SOUTH ON TUESDAY. A LEE-SIDE LOW
DEVELOPS EAST OF THE ROCKIES TONIGHT WITH A COLD FRONT SAGGING
QUICKLY SOUTH THROUGH CENTRAL MONTANA TUESDAY MORNING. AS THE FRONT
MOVES THROUGH...CIGS WILL QUICKLY DROP TO MVFR/IFR ALONG WITH A WIND
SHIFT TO THE W/NW. WINDS WILL INCREASE AND BECOME GUSTY BEHIND THE
FRONT AS WELL. SNOW IS EXPECTED TO DEVELOP ALONG AND BEHIND THE
FRONT TUESDAY MORNING WITH SNOW REACHING A LINE FROM KHLN TO KHVR BY
18Z/TUESDAY. OF NOTE...THE PRECIPITATION MAY START AS A BRIEF PERIOD
OF RAIN OR A RAIN/SNOW MIX...BUT THIS SHOULD BE SHORT-LIVED.
OTHERWISE...LOWER CIGS/VIS CAN BE EXPECTED AS THE SNOW DEVELOPS. THE
PRIMARY IMPACTS WITH THIS WINTER SYSTEM SHOULD HOLD OFF UNTIL JUST
AFTER THE CURRENT TAF PERIOD. MARTIN

&&

.PREV DISCUSSION...
/ISSUED 433 AM MST MON NOV 23 2015/

TODAY AND TONIGHT...BROAD UPPER LEVEL RIDGING GRADUALLY SHIFTS EAST
ACROSS THE NORTHERN ROCKIES AND MONTANA TODAY AND TONIGHT FOR DRY
CONDITIONS ACROSS THE FORECAST AREA THROUGH MOST OF TONIGHT.
TEMPERATURES WILL REMAIN ON THE MILD SIDE TODAY BEFORE SIGNIFICANT
CHANGES OCCUR TUESDAY.

TUESDAY AND WEDNESDAY...SHORTWAVE CURRENTLY WEST OF THE BC COAST
DIGS SHARPLY SOUTHWARD TONIGHT WITH A MID LEVEL CIRCULATION CLOSING
OFF ALONG THE PACIFIC NW COAST TUESDAY MORNING WHICH CONTINUES TO
DIG SOUTHEASTWARD INTO THE NORTHERN GREAT BASIN BY WEDNESDAY. A COLD
AIRMASS ORIGINATING IN NW CANADA WILL SURGE SOUTH TONIGHT REACHING
THE US/CAD BORDER TUESDAY MORNING AND SPREADING SOUTH THROUGH
CENTRAL AND SW MT TUESDAY AFTERNOON. MEANWHILE, MOISTURE BEING
ADVECTED NORTH AHEAD OF THE PACIFIC MID-UPPER LEVEL TROUGH/LOW WILL
STREAM NE INTO THE NORTHERN ROCKIES AND MT AS WELL DURING THE DAY
TUESDAY WITH SNOWFALL DEVELOPING INITIALLY OVER NW PORTIONS OF THE
FORECAST AREA TUESDAY MORNING AND EXPANDING S AND E ACROSS THE
REMAINDER OF THE FORECAST AREA LATE TUES AND TUES NIGHT. SNOW WILL
GRADUALLY DIMINISH FROM N TO S ACROSS THE REGION WEDNESDAY AS THE
UPPER LEVEL TROUGH SINKS FURTHER S INTO THE GREAT BASIN WITH DRIER
AIR MOVING IN FROM THE NW. MODEL CONSISTENCY REMAINS GOOD WITH AXIS
OF HIGHEST PRECIPITATION FOCUSED FROM THE ROCKY MTN FRONT SOUTH
THROUGH MOST OF CENTRAL MT AS WELL AS EASTERN PORTIONS OF SW MT.
THIS RESULTS IN ABOUT 3-6 INCHES OF TOTAL SNOWFALL FOR LOWER
ELEVATIONS, EXCLUDING AREAS ALONG THE HI-LINE WHERE ROUGHLY 1-3
INCHES IS EXPECTED. HIGHEST SNOWFALL AMOUNTS, EXCEEDING 6 INCHES,
ARE LIKELY FROM THE SOUTHERN ROCKY MTN FRONT EAST ACROSS THE CENTRAL
MT MTNS AND EASTERN MTN RANGES OF SW MT. GUSTY NORTH WINDS WILL
DEVELOP TUESDAY AS THE COLD AIRMASS SURGES SOUTH INTO THE REGION AND
ONLY SLOWLY DIMINISH ON WEDNESDAY AS COLD AIR CONTINUES TO FLOOD IN
FROM THE NORTH. BLOWING AND DRIFTING SNOW IN ADDITION TO SNOWPACKED
AND ICY ROADWAYS WILL CREATE SIGNIFICANT TRAVEL HAZARDS ACROSS MUCH
OF THE FORECAST AREA LATE TUESDAY THROUGH TUESDAY NIGHT BEFORE SNOW
AND WINDS DIMINISH WEDNESDAY. MAXIMUM TEMPERATURES ON TUESDAY WILL
OCCUR EARLY IN THE MORNING WITH TEMPERATURES FALLING INTO THE TEENS
AND TWENTIES BY LATE AFTERNOON AND EVENING. TEMPERATURES CONTINUE TO
FALL TUESDAY NIGHT AND REMAIN STEADY, GENERALLY IN THE TEENS, ON
WEDNESDAY. HOENISCH

WEDNESDAY NIGHT AND THANKSGIVING DAY...SNOW WILL END OVER NORTH-
CENTRAL MONTANA FOR AREAS NORTH OF MT-200 BEFORE MIDNIGHT WEDNESDAY
NIGHT. FOR AREAS SOUTH OF MT-200 AND ACROSS SOUTHWEST
MONTANA...LIGHT SNOW WILL PERSIST INTO THURSDAY MORNING WITH
ADDITIONAL SNOW ACCUMULATIONS IN VALLEY LOCATIONS AN INCH OR LESS
AND 1 TO 3 INCHES OVER MOUNTAIN PASSES.

HIGH TEMPERATURES ON THANKSGIVING DAY WILL BE COLD WITH HIGHS IN THE
TEENS TO NEAR 20 DEGREES. WINDS WILL GENERALLY BE LIGHT AS CANADIAN
HIGH PRESSURE BUILDS INTO THE AREA BUT WIND CHILLS MAY BE IN THE
SINGLE DIGITS AT TIMES. IF YOU PLAN ON BEING OUTDOORS...DRESS IN
WARM LAYERS AND LIMIT EXPOSURE TO THE COLD.

FRIDAY THROUGH MONDAY...FORECAST MODELS REMAIN IN GENERAL AGREEMENT
WITH DEVELOPING A BLOCKING PATTERN AS A CLOSED LOW MOVES OVER THE
GREAT BASIN REGION AND AN UPPER RIDGE BUILDS ACROSS THE EASTERN
PACIFIC. TEMPERATURES WILL REMAIN BELOW SEASONAL AVERAGES THROUGH
SUNDAY BUT A GRADUAL WARMING TREND IS EXPECTED. HIGHS ON FRIDAY WILL
BE IN THE 20S AND LOW TO MID 30S ON SATURDAY AND SUNDAY. OVERNIGHT
LOWS WILL BE IN THE SINGLE DIGITS AND TEENS. OVERALL DRY CONDITIONS
ARE ANTICIPATED OVER NORTH-CENTRAL AND SOUTHWEST MONTANA...HOWEVER
THE GFS BRINGS INCREASING MOISTURE AND POSSIBLE PRECIPITATION INTO
CENTRAL AND EASTERN MONTANA ON SUNDAY. GIVEN THE UNCERTAINTY IN THE
TRACK OF THE CLOSED LOW IN THE INTER-MOUNTAIN WEST...HAVE LEANED
MORE TOWARDS THE DRIER ECMWF SOLUTION FOR NOW. WINDS WILL GENERALLY
REMAIN LIGHT AND SOUTHEASTERLY. MLV
