AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BOISE ID
1000 AM MST TUE FEB 21 2012
.DISCUSSION...STRONG WINDS ALOFT WERE CARRYING A MOIST PACIFIC PLUME
INTO PORTIONS OF SE OREGON/SW IDAHO THIS MORNING. THIS IS RESULTING
IN SNOW IN THE MOUNTAINS WITH A RAIN/SNOW MIX IN THE LOWER VALLEYS.
SNOW LEVELS WILL BE RISING FROM SW TO NW THROUGH THE AFTERNOON BUT
WILL STAY ALL SNOW IN THE BOISE/WEST CENTRAL MTNS...INCLUDING
MCCALL. SNOW LEVELS WILL CONTINUE TO CLIMB TONIGHT AND WEDNESDAY
BEFORE A COLD FRONT ARRIVES LATE WEDNESDAY. HIGHEST QPF/SNOW AMOUNTS
WILL BE CONFINED TO HIGHER ELEVATIONS IN THE NORTH. MAIN CONCERN
WILL BE POTENTIAL FOR VERY STRONG WINDS DEVELOPING ON
WEDNESDAY...ESPECIALLY NEAR THE COLD FRONT. FORECAST IS ON TRACK FOR
NOW. WILL EVALUATE HIGH WIND WATCH THIS AFTERNOON AFTER TAKING A
CLOSER EXAMINATION OF NEW MODEL GUIDANCE.
&&
.AVIATION...WIDESPREAD MVFR WITH AREAS OF IFR AND LOCAL LIFR IN
RAIN/SNOW THROUGH 03Z WEDNESDAY. VISIBILITIES ARE EXPECTED TO
IMPROVE TO VFR ALONG AND SOUTHWEST OF A KBKE-KBOI-KTWF
LINE...INCLUDING KBNO...AFTER 20Z. MEANWHILE...AREAS NORTH AND EAST
OF THIS LINE WILL REMAIN MVFR OR LOWER THROUGH WEDNESDAY. SURFACE
WINDS WILL INCREASE TODAY TO WESTERLY OR NORTHWESTERLY AT 20
KTS...WITH GUSTS UP TO 40 KTS IN FAVORED WESTERLY-ORIENTED
VALLEYS...NEAR KJER/KTWF FOR EXAMPLE. WESTERLY UPPER LEVEL WINDS
WILL RANGE FROM 50-70 KTS AT 10K FT MSL.

.PREV DISCUSSION...
SHORT TERM...TODAY THROUGH WEDNESDAY...AT 3 AM MST - LIGHT
PRECIPITATION CONTINUED AS STRONG NORTHWESTERLY FLOW ALOFT /ON THE
EAST SIDE OF AN AMPLIFIED PACIFIC RIDGE/ TRANSPORTED PACIFIC
MOISTURE SOUTHEAST INTO OREGON AND IDAHO. EXPECT ADDITIONAL WARMING
AND RISING SNOW LEVELS TODAY AS THE RIDGE NOSES INLAND IN RESPONSE
TO A SYSTEM IN THE GULF OF ALASKA. MOIST FLOW ALOFT WILL
PERSIST...AND PRECIPITATION WILL REMAIN STEADY NORTH AND EAST OF THE
SNAKE RIVER THROUGH WEDNESDAY. DESPITE ONGOING PRECIPITATION...THE
MAIN STORY WILL BE INCREASINGLY WINDY CONDITIONS THROUGH WEDNESDAY
NIGHT DUE TO A TIGHTENING SURFACE GRADIENT AND ANOMALOUSLY STRONG
WESTERLY WINDS ALOFT.
WINDS WILL BEGIN TO INCREASE TODAY...ESPECIALLY ACROSS THE WESTERN
MAGIC VALLEY AND PORTIONS OF SOUTHEAST OREGON WHERE SPEEDS ARE
FORECAST TO PEAK JUST BELOW ADVISORY CRITERIA /GUSTS TO 45 MPH/.
EXPECT GUSTY CONDITIONS TO PERSIST OVERNIGHT TONIGHT...THEN PEAK
WEDNESDAY AFTERNOON/EVENING AS A COLD FRONT MOVES NORTH-TO-SOUTH
ACROSS THE FORECAST AREA. GUSTS UP TO 65 MPH ARE POSSIBLE
WEDNESDAY AFTERNOON AND EVENING /EVEN STRONGER ON RIDGE TOPS/ AND
A HIGH WIND WATCH REMAINS IN EFFECT FOR MUCH OF THE FORECAST AREA.
LONG TERM...WEDNESDAY NIGHT THROUGH MONDAY...NO BIG CHANGES IN THE
WEATHER PATTERN THROUGH THE MID AND LONG TERM. BROAD UPPER TROUGH
WILL CONTINUE TO RESIDE OVER THE PACIFIC NORTHWEST AND INTERMOUNTAIN
WEST. A BRIEF BREAK IN THE WEATHER THURSDAY NIGHT BEFORE THE NEXT
WARM AIR ADVECTION STORM MOVES INTO THE REGION FRIDAY. THE TRAILING
COLD FRONT WILL PUSH THROUGH KBNO LATE FRIDAY AFTERNOON AND THROUGH
THE IDAHO ZONES SATURDAY MORNING. ONCE AGAIN THE MOUNTAINS WILL BE
THE BIG WINNER ON PRECIP WITH SEVERAL NEW INCHES OF NEW SNOW. BY THE
FIRST OF THE WEEK...GFS AND THE ECM STILL KEEP A BROAD TROUGH OVER
THE REGION FOR CONTINUED UNSETTLED CONDITIONS.
