AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREAT FALLS MT
419 AM MDT MON APR 18 2011

.DISCUSSION...
TONIGHT THROUGH TUESDAY NIGHT...MOIST WESTERLY FLOW ALOFT WILL
BACK TO THE SOUTHWEST AS AN UPPER TROUGH DEVELOPS OVER THE PACIFIC
NORTHWEST TODAY. THIS UPPER TROUGH WILL MOVE INTO WESTERN MONTANA
TONIGHT AND INTO EASTERN MONTANA ON TUESDAY. A COLD FRONT ALOFT
ASSOCIATED WITH THE UPPER TROUGH WILL MOVE THROUGH SOUTHWEST
MONTANA TONIGHT AND INCREASE LIFT IN THAT AREA. AS FOR HIGHLIGHTS
WILL CONTINUE WITH THE WINTER STORM WARNING FOR THE ROCKY MOUNTAIN
FRONT FOR THIS MORNING. LIGHT SNOW SHOULD CONTINUE THERE INTO THIS
MORNING. WINTER WEATHER HIGHLIGHTS MIGHT BE NEEDED FOR THIS AREA
FOR TONIGHT INTO TUESDAY BUT RIGHT NOW AM NOT FORECASTING ANY
HEAVY SNOW. SNOW HAS DIMINISHED IN THE WINTER WEATHER ADVISORY
AREA FOR THIS MORNING SO HAVE CANCELLED IT. MODELS DIFFER ON
PRECIPITATION FORECASTS FOR TONIGHT AND TUESDAY BUT TEND TO
CONCENTRATE THE HEAVIER PRECIPITATION AMOUNTS OVER SOUTHEAST
PORTIONS OF THE FORECAST AREA. HAVE ENOUGH CONFIDENCE TO ISSUE A
WINTER STORM WARNING FOR THE MOUNTAINS OF MEAGHER COUNTY WHERE AM
COMING UP WITH AMOUNTS OVER A FOOT FOR THE CASTLE AND CRAZY
MOUNTAINS. WILL GO WITH AN ADVISORY FOR LOWER ELEVATIONS IN
MEAGHER COUNTY. OVER GALLATIN...CASCADE...JUDITH BASIN...AND
FERGUS COUNTIES AM COMING UP WITH LOW LEVEL ACCUMULATIONS TONIGHT
INTO TUESDAY MORNING AROUND 2 TO 5 INCHES WITH AMOUNTS UP TO 10
INCHES IN THE MOUNTAINS SO WILL GO WITH A WINTER WEATHER ADVISORY.
IT IS POSSIBLE THE MOUNTAINS IN THESE LATTER COUNTIES COULD SEE
A FEW ACCUMULATIONS NEAR A FOOT OR A LITTLE MORE SO AN UPGRADE TO THE
WINTER WEATHER ADVISORY FOR THE MOUNTAINS MIGHT BE NEEDED BUT AT
THIS TIME HEAVY SNOW AMOUNTS ARE NOT EXPECTED. AS THE SYSTEM MOVES
EAST TUESDAY NIGHT AND THE UPPER RIDGE DEVELOPS EXPECT SNOW TO
DIMINISH AND MOSTLY END OVER THE ENTIRE FORECAST AREA. BLANK

WEDNESDAY THROUGH MONDAY...EXPECT THE PROLONGED COOL AND UNSETTLED
SPRING/LATE WINTER WEATHER PATTERN TO CONTINUE OVER THE REGION.
FORECAST MODELS WHERE HINTING AT SOME WARMER AND DRIER AIR MOVING
INTO THE REGION BY NEXT WEEKEND...BUT THAT HAS CHANGED BACK TO
COOLER/WET WEATHER BY SUNDAY. THINGS SHOULD DRY OUT FOR A FEW HOURS
ON WEDNESDAY...AS THE REGION WILL BE IN-BETWEEN STORM SYSTEMS.
HOWEVER...BY THURSDAY AFTERNOON EXPECT INCREASING CHANCES FOR
PRECIPITATION...ESPECIALLY OVER CENTRAL AND SOUTHWEST MONTANA. THE
PRECIPITATION CONTINUES INTO FRIDAY MORNING...BEFORE DIMINISHING A
BIT ON SATURDAY. BY SUNDAY AFTERNOON...ANOTHER STORM SYSTEM WILL
AFFECT THE WESTERN PORTIONS OF THE REGION...BRINGING WITH IT ANOTHER
CHANCE FOR RAIN/SNOW. THIS SYSTEM FOR SUNDAY/MONDAY SHOULD HAVE A
BIT WARMER AIR WITH IT...SO MAINLY RAIN IS EXPECTED AT LOWER
ELEVATIONS DURING THE DAY...WITH A MIX OF RAIN/SNOW AT NIGHT. IN THE
MOUNTAINS...MAINLY SNOW IS EXPECTED. THERE WILL BE A CHANCE FOR
ACCUMULATING SNOWS THURSDAY THROUGH FRIDAY AND AGAIN SUNDAY THROUGH
MONDAY...ESPECIALLY IN THE MOUNTAINS...AND THIS WILL BE WATCHED
CLOSELY OVER THE NEXT FEW DAYS. IN TERMS OF TEMPERATURES...EXPECT
THE BELOW NORMAL TEMPERATURES TO CONTINUE...WITH WARMEST DAY LOOKING
TO BE NEXT SUNDAY...AND EVEN ON THAT DAY...AFTERNOON TEMPERATURES
SHOULD STILL AVERAGE BETWEEN 5 AND 10 DEGREES BELOW NORMAL. BRUSDA

.AVIATION...
UPDATED 0440Z.
WIDESPREAD LIGHT SNOW AND AREAS OF FOG CONTINUES TO AFFECT MUCH OF
NORTH CENTRAL MONTANA THIS EVENING. EXPECT WIDESPREAD IFR AND LIFR
CONDITIONS OVER NORTH CENTRAL MONTANA. FARTHER SOUTH...KHLN AND KBZN
WILL SEE MAINLY VFR CONDITIONS. SOME FOG DEVELOPING OVERNIGHT WILL
AFFECT MANY AREAS...INCLUDING KHLN. LIGHT SNOW AND LOW CEILINGS WILL
PERSIST INTO THE MORNING HOURS ON MONDAY. A BREAK WITH HIGHER
