AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MISSOULA MT
901 PM MST SAT NOV 4 2006

.DISCUSSION...QUICK UPDATE TO BACK OFF ON PRECIP FOR THIS EVENING FOR
WEST CENTRAL MONTANA. LARGE AREA OF LIGHT TO MODERATE RAIN MAKING
ITS WAY EASTWARD FROM THE IDAHO THIS EVENING. THIS AREA OF PRECIP
A LITTLE SLOWER THAN PREVIOUSLY FORECAST SO SLOWED THE TIMING DOWN
BY SEVERAL HOURS. OTHER THAN THIS...PREVIOUS FORECAST ON TRACK. NO
CHANGES WITH THE LATEST GUIDANCE REGARDING THE MAJOR STORM SYSTEM
TO AFFECT NORTH-CENTRAL IDAHO AND WESTERN MONTANA WITH LATE SUNDAY
NIGHT THROUGH TUESDAY.

&&

.AVIATION...A LARGE SWATH OF MOISTURE WILL PRODUCE WIDESPREAD
PRECIPITATION WITH LOWERED CEILINGS AND VISIBILITIES ACROSS MUCH OF
THE NORTHERN ROCKIES TONIGHT INTO SUNDAY. MOUNTAINS WILL ALSO BE
OBSCURED AS THE SYSTEM MOVES THROUGH...SEE APPROPRIATE TAFS AND
TWEBS.

&&

.PREV DISCUSSION... /ISSUED 235 PM MST SAT NOV 4 2006/

..EXTREME AMOUNTS OF RAIN LIKELY ACROSS NORTHWEST MONTANA AND
PORTIONS OF NORTH CENTRAL IDAHO THROUGH MID WEEK...

..BREEZY TO WINDY CONDITIONS LIKELY SUNDAY NIGHT THROUGH
WEDNESDAY...

DISCUSSION...TONIGHT THROUGH MONDAY MORNING...ATMOSPHERIC MODELS
CONTINUE TO REMAIN IN CONSISTENT AGREEMENT WITH THE SYNOPTIC
PATTERN DURING THE SHORT TERM. THUS FORECAST CONFIDENCE THROUGH
MONDAY MORNING IS QUITE HIGH. A VERY STRONG WESTERLY FLOW WILL
DRAW IN A STEADY STREAM OF SUBTROPICAL MOISTURE FROM THE PACIFIC
OCEAN CAUSING LARGE AMOUNTS OF PRECIPITATION TO FALL OVER NORTH
CENTRAL IDAHO AND MUCH OF WESTERN MONTANA BEGINNING TONIGHT AND
CONTINUING THROUGH ABOUT MID WEEK.

THE FIRST WAVE OF PRECIPITATION IS MOVING THROUGH EASTERN
WASHINGTON AT THIS HOUR AND WILL IMPACT MUCH OF NORTHWEST MONTANA
AND NORTH CENTRAL IDAHO THIS EVENING. IT WILL MOVE EAST AND
GRADUALLY SPREAD SOUTH OVERNIGHT. AS THIS WAVE PASSES AN
INCREASING PRESSURE GRADIENT ALONG WITH STRONG WINDS ALOFT WILL
CAUSE SURFACE WINDS OVER THE SALMON RIVER VALLEY AND CAMAS PRAIRIE
AREAS NEAR GRANGEVILLE TO INCREASE AND BECOME QUITE GUSTY THIS
EVENING. AT THIS TIME IT APPEARS AS THOUGH WIND GUSTS WILL BE IN
THE 40 MPH RANGE AND THUS BELOW ADVISORY CRITERIA.
HOWEVER...CONDITIONS WILL CONTINUE TO BE MONITORED THROUGHOUT THE
EVENING.

BY SUNDAY AFTERNOON THE FIRST UPPER LEVEL WAVE WILL BE EAST OF THE
DIVIDE LEAVING ONLY SCATTERED SHOWERS IN ITS WAKE ACROSS WESTERN
MONTANA AND NORTH CENTRAL IDAHO. THERE WILL BE A BRIEF BREAK IN
PRECIPITATION BETWEEN STORM SYSTEMS LATE SUNDAY AFTERNOON INTO
EARLY SUNDAY EVENING. SUNDAY NIGHT STRONG WINDS ALOFT WILL
COMBINE WITH AN INCREASING SURFACE PRESSURE GRADIENT TO PRODUCE
WIND ADVISORY CONDITIONS THROUGHOUT THE CAMAS PRAIRIE AND SALMON
RIVER VALLEY NEAR GRANGEVILLE. HOWEVER...BECAUSE THIS SITUATION
REMAINS MORE THAN 24 HOURS IN THE FUTURE WE WILL LET THE MIDNIGHT
SHIFT RE-EVALUATE AND ISSUE IF CONDITIONS WARRANT.

MONDAY THROUGH SATURDAY...ANOTHER WARM AND VERY MOIST AIRMASS
WILL SET UP OVER THE NORTHERN ROCKIES EARLY NEXT WEEK. SOUTHWESTERLY
FLOW WILL CONTINUE THE SUBTROPICAL MOISTURE TAP OVER THE PACIFIC
AND BRING PRECIPITABLE WATER VALUES OF OVER AN INCH INTO THE
REGION. THIS EXTREME AMOUNT OF ATMOSPHERIC MOISTURE WILL
TRANSLATE INTO HEAVY RAINFALL PRODUCING IMPRESSIVE RAINFALL
TOTALS...ESPECIALLY IN THE HIGHER ELEVATIONS. THE THREAT OF
MUDSLIDES IN STEEPER TERRAIN AND LOCALIZED FLOODING WILL EXIST
MONDAY INTO TUESDAY AS NORTHWEST MONTANA AND THE CLEARWATER
MOUNTAINS IN IDAHO ARE DELUGED WITH SEVERAL INCHES OF PRECIPITATION.
SNOW LEVELS WILL RISE TO ABOUT 10000 FT AS SURFACE TEMPERATURES
WARM 10 TO 15 DEGREES ABOVE NORMAL...KEEPING PRECIPITATION IN THE
LIQUID FORM. WINDS WILL ALSO BE AN ISSUE MONDAY AS THE PRESSURE
GRADIENT TIGHTENS AND STRONG MID LEVEL WINDS MIX TO THE SURFACE.
AT THIS TIME...EXPECT WINDS TO REACH ONLY ADVISORY CRITERIA OVER
THE CAMAS PRAIRIE AND HIGHER ELEVATIONS.

BY LATE WEDNESDAY...THE UPPER LEVEL JET WILL BEGIN TO SHIFT
EASTWARD...CUTTING OFF THE FEED OF SUBTROPICAL MOISTURE. RAIN
WILL GRADUALLY SUBSIDE FROM NORTH TO SOUTH THROUGH THURSDAY AND
MORE SEASONABLE TEMPERATURES RETURN TO THE REGION. MODELS ARE IN
BETTER AGREEMENT TOWARDS BUILDING A SHORTWAVE RIDGE OVER THE
NORTHWEST FOR FRIDAY...BUT THIS SCENARIO APPEARS TO BE SHORT LIVED
AS ANOTHER PACIFIC SYSTEM APPROACHES SATURDAY.
