AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GREAT FALLS MT
252 PM MDT THU APR 28 2011

.DISCUSSION...
TONIGHT THROUGH SATURDAY...THE MAIN WEATHER FEATURE TO CONTEND
WITH DURING THE PERIOD WILL CONTINUE TO BE A DEEP UPPER TROUGH
OVER THE PACIFIC NORTHWEST. THIS UPPER TROUGH WILL MOVE INTO
WESTERN MONTANA LATER TONIGHT THEN INTO CENTRAL MONTANA FRIDAY
AFTERNOON AND THEN EVENTUALLY EAST OF MONTANA FRIDAY NIGHT.
MOISTURE BEHIND A COLD FRONT IN COMBINATION WITH A WEATHER
DISTURBANCE ALOFT WILL BRING SHOWERS TO SOUTHWEST MONTANA THIS
EVENING. HIGHER MOUNTAINS COULD SEE SNOW TOTALS AROUND A HALF FOOT.
THEN LATER TONIGHT ATTENTION WILL TURN TO THE NORTH. A VERY MOIST
AIRMASS AND SIGNIFICANT LIFT ON THE WEST SIDE OF THE UPPER TROUGH
WILL SPREAD SOUTH OUT OF CANADA. THIS MOISTURE AND LIFT WILL MOVE
INTO THE FAR NORTH LATE TONIGHT THEN REACH CENTRAL MONTANA BY
MIDDAY FRIDAY AND SOUTWEST MONTANA FRIDAY AFTERNOON. THEN AS THE
UPPER TROUGH MOVES INTO THE DAKOTAS FRIDAY NIGHT A DRIER AIRMASS
WILL GRADUALLY SPREAD SOUTH. FOR SATURDAY EXPECT NORTHWEST FLOW
ALOFT OVER THE AREA. A WEATHER DISTURBANCE WILL BE APPROACHING
NORTHWEST MONTANA DURING THE AFTERNOON. WITH EXPECTED WEAK
INSTABILITY SATURDAY AFTERNOON EXPECT ISOLATED SHOWERS WITH
SCATTERED SNOW SHOWERS OVER THE MOUNTAINS. AS FOR THE WINTER STORM
WATCH FOR FRIDAY AND FRIDAY NIGHT...WILL UPGRADE THE ROCKY
MOUNTAIN FRONT AS WELL AS MEAGHER..CASCADE..AND JUDITH BASIN
COUNTIES TO A WINTER STORM WARNING. THIS UPGRADE IS BASED ON HIGH
CONFIDENCE OF HEAVY SNOW AT LEAST IN THE MOUNTAINS. UPSLOPE FLOW
WILL PLAY AN IMPORTANT ROLE OVER CENTRAL MONTANA. GUSTY NORTHWEST
WINDS WILL BE A CONCERN AND EXPECT SOME BLOWING SNOW. ELSEWHERE
IT SEEMS A WINTER WEATHER ADVISORY MIGHT SUFFICE BUT CONDITIONS
COULD POSSIBLY COME CLOSE TO WINTER STORM WARNING CRITERIA SO WILL
LEAVE AS A WINTER STORM WATCH FOR NOW. AS FOR LIGHTNING THERE IS A
SMALL THREAT FOR A STRIKE OR TWO OVER SOUTHWEST MONTANA EARLY THIS
EVENING AND OVER FAR SOUTHWEST MONTANA FRIDAY AFTERNOON. MODELS
ALSO INDICATE SOME WEAK INSTABILITY ON SATURDAY. MODELS DO NOT
INDICATE MUCH LIFT OR MOISTURE ON SATURDAY SO AT THIS TIME DO NOT
PLAN ON MENTIONING A THREAT OF THUNDER. BLANK

SATURDAY NIGHT THROUGH THURSDAY...A BROAD UPPER LEVEL TROF WILL BE
OVER THE ZONES SATURDAY NIGHT BUT MOVING EAST. NORTHWEST FLOW ALOFT
WILL CONTINUE THROUGH SUNDAY AS HIGH PRESSURE BUILDS ALOFT AND THE
AIRMASS WILL REMAIN UNSETTLED. A HIGH PRESSURE RIDGE WILL BE OVER
THE ZONES MONDAY AND THE AIRMASS WILL WARM AND DRY. HOWEVER...THE
NEXT LOW PRESSURE SYSTEM WILL BE MOVING OVER THE WEST COAST AND
MOVING THROUGH THE PACIFIC NORTHWEST MONDAY NIGHT. MOISTURE WILL
SPREAD ACROSS THE ROCKIES BY TUESDAY MORNING AND CONTINUE TO
INCREASE THROUGH TUESDAY NIGHT AS THE LOW PRESSURE TROF MOVES OVER
THE REGION. HIGH PRESSURE WILL BUILD AGAIN WEDNESDAY AND A STRONG
WARMING TREND WILL BEGIN. TEMPS WILL CONTINUE TO TREND UPWARDS
THROUGH THURSDAY AS A HIGH PRESSURE RIDGE BUILDS OVER THE ZONES.

.AVIATION...
UPDATED 1800Z.
VFR CONDITIONS SHOULD PERSIST FOR MOST OF THE FORECAST PERIOD. A LOW

UNSTABLE THIS AFTERNOON...MAINLY OVER SOUTHWEST MONTANA...MAKING
ISOLATED THUNDERSTORMS A POSSIBILITY. AN ASSOCIATED COLD FRONT WILL
CROSS THE PLAINS BY EARLY AFTERNOON. STRONG WINDS ALOFT AND MIXING
MAY CAUSE STRONG AND GUSTY SURFACE WINDS ACROSS MUCH OF CENTRAL
MONTANA. WINDS WILL WEAKEN DURING THE EVENING. RAIN SHOWERS...WITH
SNOW SHOWERS AT HIGHER ELEVATIONS...WILL CAUSE LOCAL MVFR/IFR
CONDITIONS. MOUNTAINS WILL BE OBSCURED AT TIMES IN SHOWERS.
