AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GLASGOW MT
941 PM MST SAT FEB 15 2014

.SHORT TERM...FOR NORTHEAST MONTANA...TONIGHT THROUGH MONDAY...
UPDATE...LIGHT FREEZING PRECIPITATION WILL MOVE ACROSS THE
SOUTHWESTERN SECTIONS OF NORTHEAST MONTANA OVERNIGHT. IT IS
SOMEWHAT QUESTIONABLE IF THE PRECIPITATION WILL PROVIDE WIDESPREAD
COVERAGE...HOWEVER THE RISK IS THERE FOR SOME ROAD ICING. THE
IMPACTS WARRANT AN ADVISORY TO ALERT MOTORISTS TO THE POSSIBILITY
OF ICING.       PROTON

YET ANOTHER SHORT WAVE IN THE HISTORY OF DAILY DISTURBANCES IS
HEADING TO NORTHEAST MONTANA TONIGHT. MODEL FORECAST SOUNDINGS
AND OTHER MODEL DATA INDICATE THE CHANCE FOR SOME FREEZING RAIN TO
ACCOMPANY THIS SYSTEM AS IT MOVES THROUGH NORTHEAST MONTANA. THE
PROBLEM IS THAT WITH THE LATEST MODEL RUNS COMING IN JUST BEFORE
THE EVENT BEGINS...PRECIP COVERAGE SEEMS TO TRANSITION INTO MORE
OF A SCATTERED OR SPLOTCHY NATURE. STILL FEEL THE NEED TO KEEP THE
FREEZING RAIN AND OTHERWISE MIX OF RAIN AND SNOW AND SLEET MENTIONED
IN THE FORECAST...BUT MOST LIKELY SOME LOCATIONS WILL NOT SEE ANY
OF IT WHILE OTHER SCATTERED OR ISOLATED LOCATIONS WILL PROBABLY
HAVE SOME. MODELS ALSO SHOWING SIGNS OF FOG POSSIBLE TONIGHT JUST
AHEAD OF THE AREA OF ADVANCING PRECIP. I INCLUDED THAT TOO.

MODEL AGREEMENT IS MUCH BETTER SHOWING GOOD CLEARING BEHIND THIS
WAVE SUNDAY AFTERNOON AND EVENING. THIS STRONG HIGH PRESSURE FROM
THE WEST WILL ALLOW SOME STRONGER WINDS TO MIX DOWN TO THE
SURFACE...BUT ONLY NEAR THE HIGHER ELEVATION NEAR THE LITTLE
ROCKIES. CURRENT HIGH WIND WATCH THERE LOOKS GOOD AND CHOSE TO
DEFER ANY UPGRADING TO THE NEXT SHIFT TO ALLOW THEM A BIT MORE
TIME TO FINE TUNE THOSE EXPECTED WINDS 24 TO 36 HOURS AHEAD OF TIME.

FROM SUNDAY EVENING THROUGH THE REMAINDER OF THE SHORT TERM
FORECAST PERIOD...UNEVENTFUL ZONAL FLOW REMAINS AND RESULTS ONLY
IN SOME CLOUDS AND A FEW ISOLATED FLURRIES AHEAD OF THE
APPROACHING LARGE SCALE TROUGH FROM CANADA LATE IN THE WEEK.
BMICKELSON

.LONG TERM...MONDAY NIGHT THROUGH SATURDAY...
A CLOSED UPPER LOW MOVING EAST ACROSS CENTRAL SASKATCHEWAN WILL
CREATE ZONAL FLOW INITIALLY TO BEGIN THE EXTENDED PERIOD MONDAY
EVENING. AS THE LOW MOVES SOUTHEAST TOWARD THE GREAT LAKES REGION
FLOW ALOFT LOCALLY WILL VEER TO THE NORTHWEST. WEAK EMBEDDED
DISTURBANCES ALOFT COULD PRODUCE A FEW LIGHT SHOWERS...BUT THE
MAIN EFFECT OF THE WAVE WILL BE TO SEND A COLD FRONT SOUTH THROUGH
THE REGION MONDAY NIGHT. THIS WILL COOL TEMPERATURES CLOSER TO
NORMAL FOR TUESDAY.

A SHORTWAVE PACIFIC STORM SYSTEM MOVING INTO THE PAC-NW ON TUESDAY
WILL CREATE A NARROW WAVE RIDGE FOR NORTHEAST MONTANA TUESDAY
NIGHT...RESULTING IN A WARM FRONT WITH MIXED PRECIPITATION. THE
SHORTWAVE COLD FRONT WILL REACH NEMONT BY WEDNESDAY MORNING. MUCH
COLDER AIR FOLLOWS THE COLD FRONT. AFTER THE PACIFIC STORM MOVES
ACROSS THE DIVIDE...LOW LEVEL AND UPPER LEVEL LOWS CLOSE OFF AND
STACK-UP NEAR THE INTERNATIONAL BORDER. MODELS SHOW DRY-
SLOTTING...BUT WIND WILL BE STRONG INTO WEDNESDAY EVENING.

THURSDAY...THE STORM WILL HAVE DEPARTED EAST TO BE FOLLOWED BY A
NARROW RIDGE IN ADVANCE OF ANOTHER SHORTWAVE WHICH WILL MOVE
ACROSS THE DIVIDE THURSDAY NIGHT AND FRIDAY. THIS WAVE IS EXPECT
TO PRODUCE ONLY SNOW SINCE THE COLD AIR MASS WILL REMAIN IN PLACE.
THE FOLLOWING WEEKEND SHOULD CONTINUE COLD AT AROUND 10F TO 15F
DEGREES BELOW NORMAL.

INHERITED GRIDS MATCH WELL THE LATEST GUIDANCE. THEREFORE FEW
GRIDS EDITS WERE NECESSARY. SCT

PREVIOUS DISCUSSION...
THE EXTENDED FORECAST BEGINS MONDAY NIGHT WITH NEARLY ZONAL FLOW
ACROSS THE REGION WITH AN EMBEDDED DISTURBANCE MOVING THROUGH THE
WESTERN HALF OF THE STATE. PRECIPITATION ASSOCIATED WITH THIS
DISTURBANCE WILL MOVE THROUGH EASTERN MONTANA TUESDAY EVENING
THROUGH THURSDAY MORNING. SNOW MAY TRANSITION BRIEFLY TO A
RAIN/SNOW MIX LATE WEDNESDAY MORNING. COLD AIR ADVECTION WEDNESDAY
AFTERNOON WILL ALLOW PRECIPITATION TO CHANGE BACK TO SNOW AND
GUSTY WESTERLY WINDS TO DEVELOP. A FEW LOCATIONS MAY EXPERIENCE
BLOWING AND DRIFTING OF SNOW.

A WEAK RIDGE WILL DEVELOP OVER THE NORTHERN ROCKIES IN THE WAKE OF
THE DISTURBANCE... KEEPING COOLER BUT FAIRLY DRY CONDITIONS WEDNESDAY
NIGHT THROUGH THURSDAY NIGHT FOR NORTHEAST MONTANA.

A TROUGH WILL DEVELOP OVER THE NORTHERN ROCKIES AS THE UPPER RIDGE
AMPLIFIES OFF THE WEST COAST FRIDAY MORNING THROUGH THE END OF THE
EXTENDED. MODEL SOLUTIONS CONTINUE TO DIFFER ON WHERE
PRECIPITATION WILL OCCUR AND THE QUANTITY... HOWEVER TEMPERATURES
WILL REMAIN WELL-BELOW NORMAL WITH MANY LOCATIONS WITH TEMPERATURE
DEPARTURES AROUND 15 TO 20 DEGREES. WITH THE UNCERTAINTY CHOSE TO
LEAN TOWARD CLIMO POPS. AEC
