AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BOISE ID
1000 AM MST SUN JAN 4 2009

.DISCUSSION...CURRENT FORECAST OF SUNNY BUT COLD CONDITIONS IS RIGHT
ON TARGET.  WILL NOT MAKE ANY ADJUSTMENTS TO THIS PERIOD OF THE
FORECAST.  FOCUS NOW DIRECTED TOWARD NEXT STORM TO AFFECT THE AREA
MONDAY MORNING. WILL CONTINUE TO ADDRESS THIS STORM DURING THE
SHIFT.  A HIGH PROBABILITY OF MULTIPLE WINTER HEADLINES ON THE
AFTERNOON FORECAST PACKAGE.

&&

.AVIATION...VFR CONDITIONS UNDER MOSTLY CLEAR SKIES FOR MOST OF
SOUTHWEST IDAHO AND SOUTHEAST OREGON THROUGH TODAY. CLOUDS
INCREASING LATER TODAY AS PACIFIC STORMS SYSTEM APPROACHES FROM THE
WEST. LIGHT WINDS SURFACE AND ALOFT THIS MORNING INCREASING FROM THE
SOUTHWEST TO SOUTHEAST IN THE AFTERNOON. WIDESPREAD MVFR/IFR
CONDITIONS IN SNOW EXPECTED TO AROUND 09Z OVERNIGHT AT KBNO AND
KBKE. SNOW WILL SPREAD...AHEAD OF A FAST MOVING COLD FRONT...INTO
THE KBOI AREA AROUND 13Z. GUSTY WINDS WITH PASSAGE OF THE FRONT WILL
CAUSE BLOWING AND DRIFTING SNOW REDUCING VISIBILITIES.

&&

.PREV DISCUSSION...TODAY THROUGH MONDAY...DRY AND COOL TODAY WITH
ARCTIC HIGH PRESSURE CENTERED ALONG THE NORTHERN ROCKIES. CLOUDS
WILL BEGIN TO INCREASE THIS AFTERNOON AND EVENING AS A MOIST WARM
OVERRUNNING SYSTEM MOVES INTO THE PACIFIC NORTHWEST. CURRENT PW
VALUES HAVE A LARGE AREA OF 1.25-1.5 INCHES OFF THE NORTH PACIFIC
COAST. SYSTEM LOOKS TO BE A GOOD SNOW MAKER FOR MUCH OF THE CWA BUT
THE QUESTION IS HOW MUCH SNOW WILL FALL BEFORE THE WARM ADVECTION
BRINGS SNOW LEVELS UP. WITH TEMPERATURES STARTING MONDAY MORNING
BELOW NORMAL AND SNOW FALL HELPING TO KEEP TEMPERATURES DOWN...THINK
THAT OTHER THAN IN HARNEY AND MALHEUR COUNTIES...THE REST OF THE CWA
WILL SEE ADVISORY OR WARNING SNOW AMOUNTS. THE NORTHWEST FLOW IS
FAVORABLE FOR SNOWFALL THROUGH THE UPPER TREASURE VALLEY WHERE 2 TO
4 INCHES OF SNOW IS EXPECTED TO FALL. GUSTY WINDS WILL ALSO BE A
CONCERN WITH THIS STORM AS BLOWING AND DRIFTING SNOW WILL FURTHER
REDUCE VISIBILITIES. HAVE CONTINUED THE WINTER STORM WATCH FOR BAKER
COUNTY AND THE WEST CENTRAL AND BOISE MOUNTAINS AND ADDED THE CAMAS
PRAIRIE AND UPPER TREASURE VALLEY. THE UPPER TREASURE VALLEY WILL
SEE HIGH END ADVISORY TO LOW END WARNING AMOUNTS BUT THE TIMING OF
THE HEAVIEST SNOW WILL BE DURING THE MORNING COMMUTE WHICH WILL HAVE
A LARGE IMPACT SO THE WATCH WAS ISSUED. WILL LET THE DAY SHIFT
DECIDE WHERE TO ISSUE THE FINAL WARNINGS AND ADVISORIES. SNOW WILL
LIKELY TURN TO RAIN LATE IN THE DAY BELOW 3500 FEET MAKING FOR A
SLUSHY EVENING COMMUTE MONDAY NIGHT.

LONG TERM...MONDAY NIGHT THROUGH SATURDAY...THERE IS ABOUT A 12 HOUR
WINDOW OF LIGHTER PRECIP MONDAY NIGHT BEFORE THE NEXT SLUG OF
PACIFIC MOISTURE TAKES AIM ON THE REGION. ON TUESDAY...PRECIP REALLY
GETS CRANKING ONCE AGAIN AS A WARM FRONT GRADUALLY LIFTS NORTHWARD
OVER THE AREA. SKIES MAY CLEAR ALLOWING TEMPS TO DROP TUESDAY
MORNING FOR THE PRECIP TO START AS SNOW IN THE LOWER VALLEYS...BUT
BY THE AFTERNOON THE SURGE OF WARMER AIR WILL SEND SNOW LEVELS ABOVE
VALLEY FLOORS. THE FAVORED AREAS FOR THE HEAVIEST PRECIP WILL BE THE
BOISE/WEST CENTRAL IDAHO MOUNTAINS AND THE MOUNTAINS IN BAKER COUNTY
OREGON. THE PRECIP MAY LAST INTO THURSDAY BEFORE FINALLY TAPERING
OFF AS THE MODELS BRING A PACIFIC TROUGH AND COLD FRONT THROUGH THE
REGION THURSDAY AND THURSDAY NIGHT. WINTER STORM WATCHES MAY
EVENTUALLY BE NEEDED WITH THE EVENT STARTING ON TUESDAY...BUT WITH
HEADLINES ALREADY OUT FOR MONDAY/S SYSTEM...AND A BREAK IN THE
WEATHER MONDAY NIGHT...THINK IT WOULD BE BEST TO MENTION THE HEAVY
SNOW POTENTIAL IN THE MOUNTAINS WITHIN THE CURRENT WATCH AND ALSO IN
THE HAZARDOUS WEATHER OUTLOOK. TEMPERATURES WILL RUN ABOVE NORMAL
UNTIL AFTER THE FRONT MOVES THROUGH ON THURSDAY. MODELS ARE STILL IN
AGREEMENT WITH AN UPPER RIDGE DEVELOPING ALONG THE WEST COAST FOR
DRIER WEATHER AND NEAR SEASONABLE TEMPS NEXT WEEKEND.
