AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MISSOULA MT
842 AM MST MON JAN 9 2006
.UPDATE...THE BATCH OF PRECIPITATION THAT HAS BEEN FORECAST FOR
THE PAST COUPLE OF DAYS IS MAKING ITS WAY THROUGH EASTERN
WASHINGTON THIS MORNING. THIS PRECIPITATION WILL AFFECTED
NORTHWEST MONTANA BY LATE MORNING...THEN SLOWLY MOVE SOUTHWARD
THIS AFTERNOON. SO HAVE ADJUSTED THE TIMING OF PRECIPITATION IN
THE FORECAST. ALSO THE CLOUD COVER PLAYED A MAJOR ROLE IN LOW
TEMPERATURES LAST NIGHT. NORTHWEST MONTANA HAD CLOUD COVER ALL
NIGHT SO TEMPERATURES REMAIN WARM...WHILE SOUTHWEST MONTANA AND
PORTION OF NORTH CENTRAL IDAHO HAD CLEAR SO TEMPERATURES DROP INTO
THE SINGLE DIGITS. SO ADJUSTED MAX TEMPERATURES FOR TODAY TO TAKE
INTO ACCOUNT THE DIFFERENT TEMPERATURE SPREAD. THE CLOUD COVER
WILL CONTINUE TO INCREASE THROUGH OUT THE DAY. THE FORECAST WILL
CONTINUE TO BE MONITORED FOR FURTHER UPDATES.
&&
.PREV DISCUSSION... (ISSUED 446 AM MST MON JAN 9 2006)
SHORT TERM...A VERY MOIST PATTERN WILL BEGIN OVER THE REGION
STARTING LATE THIS AFTERNOON IN NORTHWEST MONTANA. THE FIRST OF
TWO MOIST STRONG STORMS HAS ENTERED WASHINGTON STATE AND WILL MOVE
INTO NORTHWEST MONTANA LATE THIS AFTERNOON. HELPED BY A STRONG
UPPER LEVEL JET STREAM AND AMPLE SUB-TROPICAL MOISTURE...THE
POTENTIAL EXIST FOR HEAVY SNOWS. GOOD OROGRAPHICS WITH THESE
SYSTEMS WILL PROVIDE THE GREATEST AMOUNTS OF SNOWS ON WEST FACING
SLOPES...ESPECIALLY IN THE MOUNTAINS OF CENTRAL IDAHO AND
NORTHWEST AND WEST CENTRAL MONTANA. WINDS WILL BE STRONG AND GUSTY
IN EXPOSED AREAS MAINLY AT HIGHER ELEVATIONS. MODELS ARE IN
AGREEMENT ON THE COPIOUS AMOUNTS OF MOISTURE AND HAVE COME INTO
ALIGNMENT ON TIMING OF THIS EVENT.
UPGRADED THE WATCH TO WARNING IN NORTHWEST MONTANA FOR LATE THIS
AFTERNOON THROUGH WEDNESDAY. LATEST MODEL RUNS SHOW A BIT OF SLOW
DOWN TO THE SYSTEM THUS HAVE PUSHED THE WINTER STORM WATCH BACK TO
THIS EVENING THROUGH WEDNESDAY EVENING. HAVE NOT UPGRADED THE
WATCH DUE TO THE POSSIBILITY OF THE SYSTEM SLOWING A LITTLE MORE
AND THAT MOST OF THE ABUNDANT PRECIPITATION IN THE WATCH REGION
WILL OCCUR LATER TONIGHT INTO TUESDAY.
SNOW LEVELS ARE SIMILAR THROUGHOUT THE NEXT 48 HOURS. THE RELATIVELY
WARM ORIGIN OF THESE STORMS AND MOISTURE WILL KEEP SNOW ELEVATIONS
AROUND 3500-4000 FEET THROUGHOUT WEDNESDAY MORNING. ITS GOING TO
BE TOUGH FOR THE VALLEY FLOORS TO BE COLD ENOUGH TO SEE
ACCUMULATING SNOWS THROUGHOUT AS THEY WILL HOVER AROUND OR BE JUST
ABOUT THE FREEZING MARK AT NIGHT AND IN THE 30S BY DAY...THUS A
RAIN/SNOW MIX IS WHAT MANY OF THE LOWER VALLEYS...BELOW 3500-4000
FEET WILL SEE. THE OTHER QUESTION WILL BE WITH THE STRONG WINDS
ALOFT...WILL SOME VALLEYS SEE A DOWNSLOPING EFFECT TO WHICH THEY
WILL NOT SEE AS MUCH MOISTURE. WINDS AT 700 MB TONIGHT THROUGH
TUESDAY NIGHT WILL BE 40-50 KNOTS MAINLY FROM THE WEST. AT THIS
TIME IT LOOKS LIKE DOWNSLOPING WILL NOT PLAY A BIG FACTOR DUE TO
MORE OF A WESTERLY WIND COMPONENT AND A TREMENDOUS AMOUNT OF
MOISTURE SHOWN BY ALL MODELS.
LONG TERM....WEDNESDAY THROUGH MONDAY. A MOIST AND UNSTABLE
ATMOSPHERIC FLOW WILL CONTINUE TO USHER IN PACIFIC STORM SYSTEMS
THROUGHOUT MUCH OF THE LONG TERM FORECAST PERIOD. THURSDAY MORNING
A SURFACE HIGH PRESSURE SYSTEM WILL BUILD ACROSS THE NORTHERN ROCKIES
IN ASSOCIATION WITH A WEAK UPPER LEVEL RIDGE. THE WEAK RIDGING
WILL CAUSE A REPRIEVE IN OUR ACTIVE WEATHER...HOWEVER IT DOES NOT
APPEAR STRONG ENOUGH TO TAKE MENTION OF PRECIPITATION OUT OF THE
FORECAST. VALLEY INVERSIONS WILL PROBABLY STRENGTHEN OVERNIGHT
FRIDAY BEFORE YET ANOTHER PACIFIC STORM SYSTEM APPROACHES THE
INTER-MOUNTAIN WEST. SNOW LEVELS APPEAR TO BRIEFLY RISE AS A
SURFACE FEATURE MOVES ALONG THE CANADIAN BORDER ON SATURDAY. BUT
TO DROP AGAIN AS THE COLD FRONT AND UPPER LEVEL TROUGH MOVE
THROUGH THE AREA. THIS WILL RETURN THE PACIFIC NORTHWEST TO
NORTHWESTERLY FLOW WHICH WILL DRAW COOLER AIR DOWN FROM CANADA
SUNDAY INTO MONDAY. HOWEVER THERE ARE SOME MODEL TIMING ISSUES AS
THE EUROPEAN FORECAST MODEL WANTS TO DRASTICALLY SLOW THESE
SYSTEMS DOWN WHEN COMPARED TO THE GFS. WE WILL HAVE TO WAIT FOR
FURTHER MODEL VERIFICATION BEFORE THE TIMING OF EVENTS PAST FRIDAY
ARE NAILED DOWN.
AVIATION...CLOUDS WILL BE INCREASING IN COVERAGE THROUGHOUT THE DAY
IN ADVANCE OF A STRONG WINTER STORM. BY THIS EVENING...WIDESPREAD
MOUNTAIN SNOW WITH A MIX OF SNOW AND RAIN IN THE VALLEYS WILL CAUSE
LOWERED CEILINGS...REDUCED VISIBILITY AND MOUNTAIN OBSCURATIONS ACROSS
MUCH OF NORTHWESTERN MONTANA AND CENTRAL IDAHO. PLEASE SEE APPROPRIATE
TAFS AND TWEBS FOR FURTHER INFORMATION.
