AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE GREAT FALLS MT
442 AM MST SAT NOV 17 2007

UPDATED AVIATION SECTION

.DISCUSSION...

TODAY THROUGH MONDAY...THE PERIOD BEGINS WITH A FLAT RIDGE BECOMING
MORE ZONAL THROUGH THE DAY. MULTIPLE WEAK DISTURBANCES EMBEDDED IN
THE FLOW WILL MOVE THROUGH THE AREA TODAY AND TONIGHT. THE BEST
CHANCE OF PRECIP WILL BE OVER THE ROCKIES AND SOUTHWEST MONTANA
WHERE MOISTURE CONTINUES TO INCREASE. THE NOSE OF AN UPPER LEVEL JET
CROSSES THE ROCKIES LATE SATURDAY AFTERNOON AND EVENING WITH THE
CORE OF MAX WINDS APPROACHING THE NORTHERN ROCKIES AFTER
MIDNIGHT...AND MOVES INTO THE EASTERN ZONES DURING THE DAY SUNDAY.
MODEL WINDS ARE NOT AS IMPRESSIVE AS YESTERDAY BUT WILL CONTINUE THE
HIGH WIND WATCH FOR THE ROCKIES. POPS INCREASE AS AN UPPER LEVEL
SHORTWAVE MOVES THROUGH THE PACIFIC NORTHWEST AND APPROACHES THE
ROCKIES SUNDAY NIGHT. THE AIRMASS MOISTENS AHEAD OF THIS SHORTWAVE
WHILE AT THE SURFACE COLDER CANADIAN AIR MOVES SOUTH INTO THE ZONES.
LATEST RUN OF THE NAM IS PUSHING THE PRECIP FARTHER NORTH. MOUNTAINS
AREAS COULD HAVE SIGNIFICANT SNOWFALL BUT SNOW AMOUNTS ELSEWHERE
SHOULD REMAIN IN THE 2 TO 5 INCH RANGE. THE AIRMASS CONTINUES TO
COOL BUT MOST TEMPS TODAY WILL SHOW LITTLE CHANGE...AND TONIGHT
SURFACE WINDS WILL HELP KEEP OVER NIGHT LOWS MODERATE. TEMPS COOL
SUNDAY THROUGH MONDAY AS COLDER AIR PUSHES SOUTH FROM CANADA. ZELZER

MONDAY NIGHT THROUGH THURSDAY NIGHT...A BROAD UPPER LEVEL TROUGH IS
EXPECTED TO BE OVER THE FORECAST AREA DURING THE BEGINNING OF THE
PERIOD. THE MOST FAVORABLE AREAS FOR ACCUMULATING SNOW ARE ALONG THE
CONTINENTAL DIVIDE AND OVER THE SOUTHWEST MOUNTAINS. SOME STRONG MID
LEVEL FORCING WILL REMAIN OVER SOUTHWEST MONTANA THROUGH MONDAY
OVERNIGHT...WITH COLD AIR ALOFT IN PLACE. PRECIPITATION CHANCES
QUICKLY DIMINISH BY TUESDAY EVENING...WITH ISOLATED MOUNTAIN SNOW
SHOWERS REMAINING. THE COLDEST AIR OF THE FORECAST PERIOD WILL BE
PRESENT DURING OVERNIGHT TUESDAY...WITH VERY COLD LOW TEMPERATURES
LIKELY WEDNESDAY MORNING. A STRONG UPPER LEVEL RIDGE IS EXPECTED TO
PERSIST OFF THE WEST COAST THROUGH THE REMAINDER OF THE FORECAST
PERIOD...WITH DISTURBED NORTHERLY FLOW ALOFT. THE NORTHERLY FLOW
WILL PREVENT ANY APPRECIABLE WARMING THROUGH THURSDAY. PRECIPITATION
CHANCES RETURN DURING THURSDAY...WITH A WEAK STORM SYSTEM
ANTICIPATED TO DROP SOUTH FROM ALBERTA. SNOW WILL LIKELY BE CONFINED
TO THE MOUNTAINS...AS DEEP MOISTURE IS NOT ANTICIPATED TO BE PRESENT
DURING THIS TIME. ZUMPFE

FRIDAY AND SATURDAY...EXTENDED MODELS CONTINUE TO DEPICT A NORTH
FLOW OVER THE CWA THROUGH THE PERIOD. STRENGTH AND OVERALL POSITION
DIFFER IN MODELS SO DECIDED TO KEEP THINGS NEAR CLIMATOLOGY FOR
PRECIPITATION AND TEMPERATURES. A CHANCE FOR SCATTERED SNOW SHOWERS
WITH NEAR NORMAL TEMPERATURES FOR MUCH OF THE CWA IF THE CURRENT
MODELS ARE CORRECT. SAUCIER

UPDATED 1142Z.
WEAK HIGH PRESSURE OVER THE REGION WILL BE DISRUPTED BY A WEAK
