AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GLASGOW MT
947 AM MST SAT FEB 19 2011

.SHORT TERM...FOR NORTHEAST MONTANA...TODAY THROUGH MONDAY...
UPDATE...GOING FORECAST IN OVERALL EXCELLENT SHAPE. ONLY
TWEAK WAS TO TREND UP TEMPS ACROSS THE EXTREME NORTHEAST WHERE
THEY WERE ALREADY NEAR THEIR FORECAST MAX TEMPS THANKS TO AMPLE
CLOUD COVER OVERNIGHT. GILCHRIST

PREVIOUS DISCUSSION...ARCTIC HIGH PRESSURE WILL REMAIN OVER
SASKATCHEWAN THROUGH SUNDAY BRINGING BITTER COLD AIR TO NORTHEAST
MONTANA. MEANWHILE...A DEEP UPPER TROUGH ON THE PACIFIC COAST WILL
MOVE INLAND THIS WEEKEND. MOIST SOUTHWEST FLOW ALOFT WILL BRING
ACCUMULATING SNOW TO AREAS SOUTH OF THE MISSOURI RIVER TONIGHT AND
SUNDAY. MEANWHILE...NORTHEAST WINDS BETWEEN THE ARCTIC HIGH
PRESSURE TO THE NORTH AND A LOW PRESSURE SYSTEM TRACKING ACROSS
COLORADO WILL BRING GUSTY NORTHEAST WINDS TONIGHT AND SUNDAY WITH
DANGEROUS WIND CHILLS.

TODAY...THERE WILL BE A FEW FLURRIES OR LIGHT SNOW SHOWERS MAINLY
IN THE EAST LEFTOVER FROM A WEAK UPPER LEVEL DISTURBANCE THAT WILL
EXIT THE STATE THIS MORNING.

MID AND UPPER LEVEL MOISTURE WILL SURGE INTO EASTERN MONTANA BY
THIS EVENING. NORTHEAST MONTANA WILL BE ON THE BORDER BETWEEN THE
SOUTHWEST FLOW ALOFT TO THE SOUTH AND A MUCH DRIER NORTHWEST FLOW
ALOFT ACROSS THE CANADIAN PRAIRIES. THIS COMBINED WITH LOW LEVEL
DRY AIR BLOWING IN FROM THE NORTH WILL LIMIT THE NORTHERN EXTENT
OF THE SNOW. USING A BLEND OF THE GFS AND ECMWF AND APPLYING AN
ADJUSTMENT FACTOR IN THAT THE MODELS BRING THE SNOW AN AVERAGE OF
50 MILES TOO FAR NORTH IN THIS SCENARIO...THE ACCUMULATING SNOW
WILL BE ALONG AND SOUTH OF HIGHWAY 200 THROUGH WINNETT... JORDAN...
CIRCLE AND SIDNEY. AT THIS POINT...IT LOOK LIKE 4 TO 8 INCHES OF
SNOW REMAINS POSSIBLE. THERE IS STILL SOME UNCERTAINTY OVER
WHETHER THE SNOW WILL FALL INTO ADVISORY OR WARNING CRITERIA.
THERE WILL BE ENOUGH WIND FOR SOME BLOWING AND DRIFTING SNOW. WILL
MAINTAIN WINTER STORM WATCH FOR TONIGHT AND SUNDAY FOR THIS AREA
AND ADD PETROLEUM COUNTY TO THE WATCH.

AREAS NORTH OF THE MISSOURI RIVER SHOULD SEE LITTLE OR NO SNOW
FROM THIS STORM. INSTEAD...THAT AREA WILL HAVE BITTER COLD
TEMPERATURES FROM THE ARCTIC HIGH TONIGHT INTO SUNDAY WHICH WILL
COMBINE WITH THE NORTHEAST WINDS TO DROP WIND CHILLS NEAR 40 BELOW
WHICH IS THE WIND CHILL WARNING THRESHOLD. IN ADDITION...THERE
WILL BE ENOUGH WIND TO AT LEAST DRIFT THE SNOW THAT THE AREA
RECEIVED ON THURSDAY. WITH THE WIND CHILL BEING THE GREATER DANGER
OF THE TWO...WILL ISSUE WIND CHILL WATCH FOR TONIGHT AND SUNDAY
FOR AREAS NORTH OF THE MISSOURI RIVER.

THE STORM ALONG WITH THE UPPER TROUGH MOVES TO THE EAST SUNDAY
EVENING WHILE THE ARCTIC HIGH PRESSURE LINGERS OVER THE REGION FOR
ANOTHER VERY COLD NIGHT. THE HIGH MOVES TO THE EAST ON MONDAY
ALLOWING TEMPERATURES TO MODERATE WITH DRY WEATHER FORRESTER

.LONG TERM...MONDAY NIGHT THROUGH SATURDAY...
THE EXTENDED PERIOD BEGINS WITH WESTERLY FLOW ALOFT FOR SEASONAL
TEMPERATURES ON TUESDAY. HOWEVER A LONG WAVE TROUGH BEGINS TO DROP
SOUTH FROM CANADA THAT WILL AFFECT NORTHEAST MONTANA THROUGH THE
REMAINDER OF THE PERIOD WITH MUCH COLDER TEMPERATURES AND AN
INCREASING CHANCE FOR ACCUMULATING SNOW BY MID WEEK. HOWEVER THERE
REMAINS DISAGREEMENT BETWEEN MODELS WITH THE ECMWF MUCH DRIER AND
COLDER THAN THE GFS.

TUESDAY/TUESDAY NIGHT...THE ARCTIC COLD FRONT POISED TO THE
NORTHWEST OF NEMONT WILL MOVE INTO THE AREA TUESDAY NIGHT...
BRINGING IN A FEW SNOW SHOWERS.

WEDNESDAY AND BEYOND...THE COLD FRONT CONTINUES ON SOUTH OF THE
FORECAST AREA WHILE FLOW ALOFT SENDS PACIFIC MOISTURE OVER THE
FRONT. THE POSITION OF THE FLUCTUATING ARCTIC FRONT WILL DETERMINE
WHERE THE SNOW FALL. NORTH OF THE FRONT A POOL OF VERY FRIGID AIR
WILL LIKELY KEEP THE NORTHERN ZONES MOSTLY DRY. IT IS POSSIBLE
THAT THE ARCTIC BOUNDARY WILL REMAIN SOUTH OF THE CWA TO SEND MOST
OF THE MOISTURE EAST ACROSS SOUTHERN MONTANA. ALTHOUGH UNCERTAINTY
INCREASES BY THE WEEKEND...FOR NOW IT LOOKS COLDER AND DRIER. SCT

&&

.AVIATION...
MOISTURE ALOFT RIDING OVER A FLUCTUATING ARCTIC STATIONARY FRONT
WILL BRING MVFR OVERCAST TO THE AREA TODAY...ALONG WITH OCCASIONAL
LIGHT SNOW. A SURFACE HIGH PRESSURE AREA IN SOUTHERN SASKATCHEWAN
WILL GENERATE NORTHEASTERLY WINDS OF AROUND 10 KTS. THE SURFACE
HIGH WILL SLIDE SOUTH TONIGHT WHICH COULD BRING CLEARING TO THE
NORTHERN TAF SITES. KSDY AND KGDV WILL LIKELY EXPERIENCE MORE
SNOWFALL THROUGH THE END OF THE TAF CYCLE...THREE TO FIVE INCHES
POSSIBLY. SCT/BMICKELSON

&&

.HYDROLOGY...
THE MUSSELSHELL RIVER IS NOW BELOW FLOOD STAGE. AT 11Z...THE MOSBY
GAGE READ 7.4 FEET AND CONTINUES TO FALL. THE FLOOD WARNING FOR
PETROLEUM AND WESTERN GARFIELD COUNTIES HAS BEEN CANCELLED.

THE MILK RIVER AT DODSON REMAINS HIGH AT 18.0 FEET THIS MORNING AND
SHOULD CONTINUE RUNNING HIGH THROUGH THE WEEKEND. THE BEAVER CREEK
AROUND SACO IS RUNNING HIGH. THE BEAVER CREEK FLOWS WERE CAUSED
BY THE EARLIER WARM SPELL THIS WEEK AND THE WATER IS NOW JUST
GETTING DOWN TO THE MILK RIVER VALLEY. GOING TO HAVE TO MONITOR
THIS CLOSELY FOR ICE JAM FLOODING THE NEXT 36 HOURS. LAW
ENFORCEMENT FRIDAY EVENING REPORTED ABOUT 5 FEET OF WATER RUNNING
OVER THE ICE ON BEAVER CREEK WHICH WAS AT 2.4 FEET. WELL BELOW
ZERO TEMPERATURES THIS WEEKEND WILL LIKELY FREEZE THIS WATER. CONCERNED
INTERESTS IN WESTERN VALLEY COUNTY SHOULD CLOSELY MONITOR THE MILK
RIVER FOR RAPID FLUCTUATIONS THIS WEEKEND AS THIS WATER PASSES
DOWNSTREAM. FORRESTER
