AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GLASGOW MT
523 PM MST TUE FEB 1 2011

.SHORT TERM...FOR NORTHEAST MONTANA...TONIGHT THROUGH THURSDAY...
VERY COLD AIR HAS SETTLED INTO THE RIVER VALLEYS OF NORTHEAST
MONTANA AS ARCTIC HIGH SLIDES TO THE SOUTH. WARMER AIR ALREADY
MOVING IN ALOFT AS INDICATED BY THE ABOVE ZERO TEMPERATURES IN
CENTRAL MONTANA BUT REMAINED AT -15 TO -20 IN THE VALLEYS. EXPECT
SITUATION TO CONTINUE OVERNIGHT...WITH THE MILK/MISSOURI VALLEYS
RETAINING THE COLD AIR. WINDS WILL REMAIN LIGHT FROM THE
SOUTHEAST...WITH OCCASIONAL PUFFS TO DROP WIND CHILLS TO 40 BELOW
OR MORE. FOR NOW WILL KEEP WIND CHILL ADVISORY GIVEN EXPECTED
LIGHT WINDS...BUT MAY NEED UPDATED LATER TO A WARNING IF WINDS
COME UP OR TEMPERATURES FALL MORE THAN EXPECTED.

DO NOT EXPECT WIND CHILL ISSUES TO LAST PAST WEDNESDAY MORNING AS
UPPER RIDGE FOLDS OVER INTO WESTERN CANADA SPREADING WARM AIR
SOUTHWARD. EXPECT MOST AREAS TO SEE READING ABOVE ZERO BY
WEDNESDAY AFTERNOON AND LIKELY NEAR OR ABOVE FREEZING BY THURSDAY.
EXCEPTION WILL BE IN THE LOWER MILK/MISSOURI BASIN WHERE COLD AIR
MAY BE DIFFICULT TO SCOUR OUT.

.LONG TERM...THURSDAY NIGHT THROUGH TUESDAY...
THE PERSISTENT UPPER RIDGE ALONG THE WEST COAST WILL KEEP
NORTHWESTERLY FLOW ALOFT OVER NORTHEAST MONTANA THROUGHOUT THE
EXTENDED PERIOD. AN EMBEDDED SHORT-WAVE DISTURBANCE IN THIS UPPER
FLOW WILL SLIDE INTO WESTERN NORTH DAKOTA AND MINNESOTA THURSDAY
NIGHT AND FRIDAY. THIS WAVE WILL NUDGE THE STATIONARY ARCTIC FRONT
SOUTHWEST INTO THE FORECAST AREA.

THE STATIONARY BOUNDARY MOVES FARTHER WEST FRIDAY NIGHT MEETING
OVERRUNNING MOISTURE. THERE ARE DIFFERENCES BETWEEN ECMWF AND THE
GFS WHERE THE BOUNDARY WILL BE...WHICH WILL DETERMINE WHERE ANY
RESULTING MOISTURE FALLS. AVAILABLE QPF RANGES AROUND 0.05-0.10
INCH.

SATURDAY THROUGH SUNDAY...A POLAR VORTEX OVER NORTHERN CANADA WILL
ROTATE A WAVE AROUND ITS WEST SIDE WHICH WILL RUN OVER THE LOCAL
AREA THIS WEEKEND DROPPING TEMPERATURES SIGNIFICANTLY BELOW
AVERAGE ONCE AGAIN AND CREATING CONDITIONS FOR ACCUMULATING SNOW.
BASED ON QPF IN THE 12Z MODELS INCREASED CHANCE POPS FOR SATURDAY
NIGHT.

SUNDAY NIGHT THE WAVE MOVES TO OUR SOUTH WILL BE REPLACED BY AN
ARCTIC SURFACE HIGH...ENDING ANY SNOW THREAT. THE ARCTIC AIR
QUICKLY MOVES ON BY TUESDAY AS WARMER AIR PUSHES IN FROM THE WEST.
ADJUSTED SUNDAY/SUNDAY NIGHT TEMPS DOWN IN COORDINATION WITH
SURROUNDING OFFICES.

FEW OTHER CHANGES WERE NECESSARY TO THE EXTENDED FORECAST..OTHER
THAN FOR BORDER COORDINATION. SCT

PREVIOUS DISCUSSION...
THURSDAY NIGHT THROUGH FRIDAY...AN UPPER LEVEL SHORTWAVE SLIDES
DOWN THE EASTERN SIDE OF LARGE UPPER LEVEL RIDGE OVER THE WEST
COAST. THIS WILL PUSH A WEAK BACK DOOR COLD FRONT INTO EASTERN
MONTANA. MODELS ARE HINTING AT SOME LIGHT QPF FOR THE EASTERN
ZONES BUT THE MAJORITY OF THE QPF REMAINS IN NORTH DAKOTA. THERE
IS A SMALL AMOUNT OF QPF THAT MAKES IT INTO THE NORTHEASTERN ZONES
BUT THE MODELS VERY ON THE DEGREE OF MOISTURE DECIDE TO CONTINUE
WITH DRY CONDITIONS THAT WERE ALREADY IN THE ZONES.

THE ONE THING THIS SHORTWAVE WILL DO ON FRIDAY IS SINK DOWN TOWARD
THE OHIO VALLEY AND OPEN UP A LARGE UPPER TROUGH OVER THE SOUTHERN
PLAINS. THIS WILL FORCE THE UPPER RIDGE BACK OVER THE PACIFIC
WHICH WILL OPEN UP THE GULF OF ALASKA UP TO TRANSPORT MOISTURE
INTO THE NORTHERN PLAINS FRIDAY NIGHT THROUGH SUNDAY NIGHT. FRIDAY
NIGHT THROUGH SATURDAY NIGHT IS A LITTLE IFFY AT THIS POINT WITH
THE WEAK COLD FRONT ACROSS THE REGION. 850 BM TEMPERATURES WARM UP
ABOVE FREEZING OVER THE WESTERN ZONES AND THE GFS BUFR SOUNDINGS
ARE SHOWING FREEZING DRIZZLE OR A WINTRY MIX.

THE HUDSON BAY LOW WILL SEND ANOTHER SHOT OF ARCTIC AIR TOWARDS
NEMONT. THE STRONG ARCTIC FRONT WILL ARRIVE SATURDAY NIGHT AND
ALL PRECIPITATION SHOULD CHANGE OVER TO SNOW AT THAT POINT. IT
LOOKS LIKE THE PRECIP WILL LAST UNTIL MONDAY MORNING BEFORE THE
FRONT TAKE THE BULK OF THE PRECIPITATION SOUTH OF THE REGION.
MONDAY THROUGH TUESDAY MORNING WILL BE ANOTHER EXTREMELY COLD
PERIOD ACROSS THE REGION. SLIGHT WARMING ON TUESDAY THROUGH
WEDNESDAY WITH DRY CONDITIONS. RSMITH

&&

.AVIATION...
AN UPPER LEVEL RIDGE PARKED ALONG THE WEST COAST WILL MAINTAIN
NORTHERLY FLOW ALOFT OVER EASTERN MONTANA TONIGHT AND WEDNESDAY.
SATELLITE IMAGERY REVEALS FEW...IF ANY...CLOUDS UP-STREAM IN THE
UPPER FLOW. THE ARRIVAL OF A WARM FRONT WEDNESDAY WILL BRING IN
SOME MID-LEVEL CLOUDS BY AFTERNOON. WITH SURFACE HIGH PRESSURE IN
PLACE TONIGHT OVER THE REGION...CONDITIONS WILL REMAIN VFR AT ALL
TERMINALS...EXCEPT FOR PATCHY FREEZING FOG THAT MIGHT DEVELOP
LATER TONIGHT AND WEDNESDAY MORNING. GENERALLY SOUTHWESTERLY WINDS
WILL RANGE AROUND 5 TO 10 KTS. SCT
