AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREAT FALLS MT
401 AM MDT FRI APR 18 2008

.DISCUSSION...
MODELS ARE COMING INTO PRETTY GOOD AGREEMENT WITH REGARD TO THE
WINTER STORM FOR THE AREA THIS WEEKEND. BUT FIRST OF ALL FOR TODAY
A WEAK SHORTWAVE WILL MOVE ACROSS SW AND CENTRAL MONTANA LATER
THIS AFTERNOON AND EVENING. THE AIRMASS WILL BECOME UNSTABLE OVER
SW MONTANA AND THERE IS A THREAT OF THUNDERSTORMS. IT APPEARS
THERE IS ENOUGH INSTABILITY AND MOISTURE ALOFT TO GENERATE GUSTY
WINDS WITH SOME OF THE SHOWERS/THUNDERSTORMS AND WILL MENTION THIS
IN THE FORECAST. DECREASED POPS IN THE EAST FOR LATER TONIGHT AS
THE SHORTWAVE IS EXPECTED TO BE EAST OF THE AREA. BUT THEN WILL
BEGIN TO SEE AN INCREASE IN MOISTURE IN THE WEST AHEAD OF THE
DEVELOPING UPPER LOW OVER THE PACIFIC NORTHWEST. MEANWHILE A
CANADIAN COLD FRONT WILL MOVE SOUTH OVER MOST OF THE AREA TONIGHT.
AS THE UPPER LOW CONTINUES TO DEVELOP OVER THE PACIFIC NORTHWEST
ON SATURDAY MOISTURE AHEAD OF IT WILL INTERACT WITH THE COLD
AIRMASS TO PRODUCE SNOW OVER THE PLAINS AND THE NORTHERN PORTION
OF SW MT. THIS INTERACTION WILL CONTINUE INTO SUNDAY WHEN A
PORTION OF THE UPPER LOW MENTIONED ABOVE MOVES INTO SW MONTANA. BY
LATE IN THE DAY COULD BEGIN TO SEE A DECREASE IN MOISTURE OVER SW
MT. AS FOR THE WINTER WEATHER HIGHLIGHTS..HAVE ENOUGH CONFIDENCE
TO UPGRADE THE WINTER STORM WATCH TO A WARNING OVER THE PLAINS FOR
SATURDAY AND SUNDAY. WILL DELAY THE WARNING OVER HILL AND BLAINE
COUNTIES UNTIL SATURDAY NIGHT AS IT WILL BE AWHILE BEFORE MOISTURE
REALLY INCREASES IN THAT PARTICULAR AREA. CONFIDENCE IS LOWER OVER
FAR SW MONTANA SO WILL CONTINUE WITH THE WINTER STORM WATCH THERE.
WILL ALSO RESTRICT IT TO ABOVE 6000 FEET AS DO NOT SEE ALL THAT
MUCH SNOW FOR THE LOWER VALLEYS. ALSO WITH THIS WATCH WILL DELAY
IT UNTIL SATURDAY NIGHT WHEN RELATIVELY HIGH SNOW LEVELS DURING
THE DAY SATURDAY BEGIN TO LOWER. BLANK

SUNDAY NIGHT THROUGH WEDNESDAY NIGHT...EXPECT A RATHER COLD AND
WINTRY WEATHER PATTERN TO RESIDE OVER THE REGION THROUGH THIS
PERIOD...THUS SPRING LIKE WEATHER WILL BE ON HOLD FOR SEVERAL DAYS.
WITH THE MAIN UPPER TROF RESIDING OVER THE REGION SUNDAY NIGHT
THROUGH MONDAY...EXPECT THE CHANCE FOR SNOW TO CONTINUE...ESPECIALLY
OUT IN THE HAVRE AND LEWISTOWN AREAS. AS THE UPPER LEVEL LOW SLOWLY
BEGINS TO MOVE NORTHEASTWARD UP INTO CENTRAL CANADA IN THE
TUESDAY/WEDNESDAY TIME FRAME...THE CHANCES FOR SNOW WILL SLOWLY
DECREASE...WITH THE BEST CHANCES FOR SNOW MAINLY IN THE MOUNTAINS BY
LATE WEDNESDAY AFTERNOON. EXPECT VERY COOL TEMPERATURES OVER THE
REGION DURING THIS PERIOD...WITH AFTERNOON HIGHS CLOSE TO 30 DEGREES
BELOW NORMAL ON MONDAY...THEN SLOWLY WARMING TO NEAR 20 DEGREES
BELOW NORMAL BY WEDNESDAY. OVERNIGHT LOWS WILL BE VERY WINTER
LIKE...WITH TEMPERATURES GENERALLY RANGING FROM TEENS AT LOWER
ELEVATIONS...TO THE SINGLE DIGITS IN THE MOUNTAINS. BRUSDA

THURSDAY THROUGH FRIDAY...MODELS ARE IN BASIC AGREEMENT DURING THIS
PERIOD...WITH JUST MINOR DIFFERENCES IN TIMING AND AMPLITUDE OF
FEATURES. THE BIGGEST DIFFERENCE IS...DESPITE SIMILAR PLACEMENT OF
FEATURES...HEIGHTS ARE QUITE A BIT LOWER ON THE ECMWF. A BLENDED
FORECAST WOULD INDICATE A QUASI-STATIONARY UPPER LOW PRESSURE SYSTEM
OVER CENTRAL CANADA...RESULTING IN A MOIST NORTHWESTERLY FLOW ACROSS
THE FORECAST AREA. WEAK DISTURBANCES IN THIS FLOW WOULD BE
RESPONSIBLE FOR MOSTLY CLOUDY SKIES. WITH THIS UNSETTLED PATTERN
ISOLATED RAIN OR SNOW SHOWERS ARE EXPECTED AT LOWER ELEVATIONS WITH
SCATTERED SNOW SHOWERS OVER MOST MOUNTAINS. A GRADUAL MODERATION OF
TEMPERATURES IS EXPECTED...BUT TEMPERATURES WILL STILL REMAIN WELL
BELOW SEASONAL AVERAGES. EK

&&

.AVIATION...
WESTERLY FLOW ALOFT WILL REMAIN OVER THE AREA THROUGH FRIDAY
MORNING. MOISTURE WILL SLOWLY INCREASE THROUGH THE NIGHT FOR
INCREASING MID AND HIGH LEVEL CLOUDS ACROSS THE AREA. BY 18Z FRIDAY
THE FLOW WILL BECOME MORE SOUTHWESTERLY AS A STRONG UPPER LEVEL
TROUGH WORKS ITS WAY INTO WESTERN CANADA...BRINGING EVEN MORE CLOUD
COVER AND ISOLATED TO SCATTERED SHOWERS TO THE REGION. VFR
CONDITIONS WILL PREVAIL. BREEZY TO WINDY CONDITIONS WILL CONTINUE
THROUGH THE NEXT 24 HOURS OVER THE PLAINS. THOMSON
