NATIONAL WEATHER SERVICE BOISE ID
322 AM MST FRI JAN 4 2008
.SHORT TERM...TODAY THROUGH SATURDAY...STRONG SERIES OF STORMS
STILL PROGGED TO COME INTO THE PAC NW AND DOMINATE OUR WEATHER
THROUGH THE WEEKEND. FIRST WEAK COLD FRONT IS BY US...WITH A MUCH
STRONGER SYSTEM POISED TO BRING US STRONG WINDS AND INCREASING
HIGH ELEVATION SNOWFALL DURING THE DAY TODAY. THE HEAVY HIGH
ELEVATION SNOWS WILL LAST WELL INTO SATURDAY. THE HEADLINES WILL
BE CONTINUED WITHOUT CHANGE. LATEST MODELS INDICATE SOME
DIFFERENCES IN TIMING AND PLACEMENT OF QPF...AND HAVE MADE SOME
ADJUSTMENTS TO THESE GRIDS. HOWEVER...THESE ADJUSTMENTS ARE NOT
SUFFICIENT TO WARRANT A CHANGE IN THE WINTER STORM WARNING.
THE NEXT FRONT SHOULD MOVE THROUGH SE OREGON LATE THIS AFTERNOON...
AND THROUGH SOUTHWEST IDAHO THIS EVENING. HAVE MASSAGED POPS TO
INDICATE A BETTER CHANCE OF RAIN AND SNOW IN SE OREGON BEFORE
00Z...WITH THE BEST CHANCE IN SW IDAHO AFTER 00Z. SNOW LEVELS WILL
RISE SHARPLY IN THE STRONG WARM AIR ADVECTION PATTERN AHEAD OF THE
NEXT SYSTEM. SNOW LEVELS SHOULD BRIEFLY RISE ABOVE 5000 TO 6000
FEET EARLY FRIDAY EVENING...BEFORE PLUMMETING DOWN TO GROUND LEVEL
BY SATURDAY AT SUNRISE. THAT MEANS SATURDAYS CONVECTIVE SNOW
SHOWERS WILL REACH THE GROUND EVEN IN THE VALLEYS. SOME OF THESE
COULD BE VIGOROUS WITH VERY COLD TEMPERATURES ALOFT HELPING TO
CREATE SIGNIFICANT INSTABILITY.
.LONG TERM...SATURDAY NIGHT THROUGH THURSDAY...THE PROGRESSIVE WET
PATTERN CONTINUES WITH RELATIVELY MILD TEMPERATURES...I.E. NEAR
NORMAL. THE WETTEST DAYS WILL BE SUNDAY AND TUESDAY...BOTH RESULTING
FROM WARM OVERRUNNING AHEAD OF EASTWARD MIGRATING SHORTWAVE TROUGHS.
MODELS STILL SHOW FAIRLY GOOD AGREEMENT AND CONTINUITY THROUGH
MONDAY. AFTER THAT THE ECMWF FALLS OUT OF PHASE WITH THE U.S.
MODELS...WANTING FASTER TIMING OF FEATURES. HOWEVER THAT PROBABLY
WONT MAKE MUCH DIFFERENCE IN SENSIBLE WEATHER. ONLY MINOR
ADJUSTMENTS WERE MADE TO TEMPERATURES AND POPS.
&&
.AVIATION...CONDITIONS WILL BE MAINLY VFR IN THE SNAKE RIVER VALLEY
WITH WIDELY SCATTERED RAIN SHOWERS. STRONG PRESSURE GRADIENTS FOR
SOUTHEAST SURFACE WINDS PLUS WARM AIR ADVECTION WILL CONTINUE THE
DOWNSLOPING OFF THE OWYHEES TODAY RESULTING IN MOST PRECIPITATION
AND LOWEST AVIATION CONDITIONS OVER THE MOUNTAINS. FOR THE MOUNTAINS
TODAY EXPECT WIDESPREAD IFR/LIFR IN SNOW ALONG WITH TERRAIN
OBSCURATION. CONDITIONS WILL DETERIORATE LATE THIS AFTERNOON THROUGH
TONIGHT WITH MVFR CEILINGS AND RAIN SPREADING INTO THE LOWER VALLEYS.
SURFACE WINDS WILL BE STRONG SOUTHEAST TODAY DECREASING TONIGHT.
WINDS ALOFT WILL BE STRONG SOUTHWEST.
