AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MISSOULA MT
849 AM MST WED FEB 14 2007

.UPDATE...SOME WEAK BANDING OF SNOW SHOWERS WAS TAKING PLACE THIS
MORNING WITH MOST AREAS SOUTH AND EAST OF MISSOULA REPORTING SNOW.
IN GENERAL...NEW SNOW ACCUMULATIONS OVERNIGHT RANGED FROM A TRACE
TO ONE INCH. HOWEVER...MANY LOCATIONS ALONG THE CONTINENTAL DIVIDE
DID RECEIVED AS MUCH AS 4 INCHES. SHOWERS WILL CONTINUE THROUGH
THE REMAINDER OF THE DAY...BUT WILL TAPER OFF TO SCATTERED DURING
THE AFTERNOON. AREAS ACROSS NORTHWEST MONTANA HAVE ALREADY SEEN
A REDUCTION TO SHOWER ACTIVITY AS DRIER..MORE STABLE AIR PUSHES IN
FROM CANADA.

HAVE ALREADY UPDATED THE FORECAST TO INCREASE POPS IN WEST-
CENTRAL MONTANA...LOWER POPS IN NORTHWEST MONTANA...AND TWEAK
MAXIMUM TEMPERATURES FOR TODAY. NO OTHER CHANGES PLANNED FOR THIS
MORNING.

&&

.AVIATION...SCATTERED SNOW SHOWERS WILL CONTINUE TO PLAGUE CENTRAL
AND SOUTHERN ROUTES THROUGH TODAY LOWERING CEILINGS AND
OBSCURING MOUNTAINS. WIDESPREAD PRECIPITATION WILL MOVE INTO THE
REMAINDER OF THE ROUTES LATE TONIGHT. PLEASE SEE APPROPRIATE TAFS
AND TWEBS FOR DETAILS.

&&

.PREV DISCUSSION... /ISSUED 255 AM MST WED FEB 14 2007/

DISCUSSION...TODAY...PERSISTENT PRECIPITATION THROUGH CENTRAL
WESTERN MONTANA IS EXPECTED TO CONTINUE THROUGH THE MORNING.
MODELS SHOW A GOOD SET UP FOR SNOW BANDING OVERNIGHT LAST
NIGHT...AND CONTINUING INTO THE MORNING HOURS TODAY. THIS IS
MAINLY EAST OF THE MISSION...MISSOULA...AND BITTERROOT VALLEYS TO
THE GREAT DIVIDE. SNOW BANDS ARE EXPECTED TO DIMINISH THIS
AFTERNOON AS WARM AIR ALOFT MOVES OVER THE REGION...STABILIZING THE
ATMOSPHERE. DURING THE MORNING HOURS...MOST OF CENTRAL WESTERN
MONTANA SHOULD SEE LIGHT ACCUMULATIONS WITH MODERATE SNOW WHERE
SNOW BANDS HAVE SET UP. LIGHT...MAINLY MOUNTAIN SHOWERS ARE
EXPECTED TO CONTINUE THROUGH THE AFTERNOON.

TONIGHT THROUGH THURSDAY...SOME INTERESTING WEATHER IS EXPECTED AS
NEXT PACIFIC STORM SYSTEM MOVES THROUGH THE INTER MOUNTAIN WEST.
THE HIGH PRESSURE RIDGE IS FLATTENED AND THE UPPER FLOW BECOMES
ZONAL WITH A SERIES OF DISTURBANCES RIPPLING THROUGH THE REGION.
THE SURFACE PRESSURE GRADIENT INCREASES FROM THE SOUTH AND
SUPPORTIVE WINDS ALOFT SUGGESTS THAT THE AIR MASS WILL UNDERGO
CONSIDERABLE WARMING THURSDAY. LOOKS AS THOUGH PRECIPITATION WILL
BEGIN IN EARNEST LATE TONIGHT OVER THE NORTH CENTRAL IDAHO ZONES
WHEN SNOW LEVELS REMAIN LOW. AT THIS TIME MODELS HAVE SOME
DISCREPANCIES ON TIMING AND AMOUNT OF PRECIPITATION. WILL
THEREFORE HOLD OFF ON ANY HIGHLIGHTS BUT WILL CONTINUE TO MONITOR
LATER RUNS FOR BETTER AGREEMENT. MUCH OF THE LOWER ELEVATION
PRECIPITATION IS EXPECTED TO CHANGE TO RAIN DURING THE DAY
THURSDAY. HIGHER MOUNTAINS STILL LOOK TO RECEIVE A GOOD DOSE OF
SNOW. AT THIS TIME...SNOWFALL ACCUMULATIONS STILL LOOK TO FIT
ADVISORY CRITERIA...WITH SOME HIGHER WEST-FACING SLOPES RECEIVING
EVEN MORE.

THURSDAY NIGHT THROUGH MONDAY...ANOTHER VIGOROUS WEATHER SYSTEM IS
EXPECTED TO IMPACT NORTHERN IDAHO AND WESTERN MONTANA WITH
SIGNIFICANT MOUNTAIN SNOW THURSDAY NIGHT INTO EARLY FRIDAY. THIS
AGAIN MAY BE ANOTHER HIGHLIGHT PERIOD FOR WINTRY CONDITIONS OVER
MOST MOUNTAIN PASSES. HOWEVER...VALLEYS SHOULD REMAIN RELATIVELY
MILD...ESPECIALLY COMPARED TO CURRENT CONDITIONS. HIGH PRESSURE
AND A RELATIVE WARM AIR MASS IS EXPECTED TO RETURN SATURDAY INTO
SUNDAY. ALTHOUGH SOME VALLEY INVERSIONS WILL FORM. IN
GENERAL...TEMPERATURES SHOULD BE WELL ABOVE NORMAL SATURDAY AND
SUNDAY. MODELS SEEM IN FAIR AGREEMENT WITH THESE CHANGES. IN THE
LONGEST TERM...THERE IS GROWING EVIDENCE THAT A MORE PROGRESSIVE
FLOW PATTERN WITH A SERIES OF PACIFIC WEATHER SYSTEMS MAY IMPACT
THE REGION EARLY NEXT WEEK.
