AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BOISE ID
340 AM MST TUE JAN 29 2008
.SHORT TERM...TODAY THROUGH WEDNESDAY...LITTLE CHANGE TO PREVIOUS
THINKING WITH REGARD TO STRENGTH AND TIMING OF THE SNOW EVENT TODAY
THROUGH THIS EVENING. WATER VAPOR AND TPW SATELLITE IMAGERY CONFIRMS
MOISTURE PLUME ASSOCIATED WITH APPROACHING PACIFIC TROUGH HAS MOVED
INLAND. DEEP MOISTURE AND LIFT ALONG WITH FAVORABLE LOW LEVEL
CONVERGENCE/UPPER LEVEL DIVERGENCE COUPLET WILL SUPPORT ABOUT A
12-18 HOUR PERIOD OF LIGHT TO MODERATE SNOW TODAY THROUGH EARLY
THIS EVENING. TEMPERATURES WILL BE COLD ENOUGH FOR SNOW DOWN TO THE
LOWEST ELEVATIONS AND HAVE THUS REMOVED REFERENCES TO POSSIBLE
RAIN/SNOW MIX IN THE LOWER VALLEYS. QPF AMOUNTS WERE A LITTLE TOO
LOW IN HARNEY AND MALHEUR COUNTIES TODAY AND BY RAISING THEM
SLIGHTLY SNOW AMOUNTS WILL SUPPORT A SNOW ADVISORY. THE REST OF THE
ADVISORIES AND WARNINGS WILL REMAIN PRACTICALLY THE SAME WITH REGARD
TO TIMING BUT WILL WORD THE SNOW AMOUNTS A BIT HIGHER IN THE
VALLEYS. NAM12 CONTINUES TO SHOW A STRIP OF LITTLE TO NO QPF ALONG
THE SNAKE RIVER ALONG THE SOUTHERN EDGE OF THE TREASURE VALLEY
INFERRING A RAIN SHADOW EFFECT...BUT STILL EXPECTING MOST OF THE
AREA BETWEEN MOUNTAIN HOME AND ONTARIO TO RECEIVE 2-4 INCHES OF
SNOW BEFORE ENDING THIS EVENING. SOUTHWEST WINDS OF 15-25 MPH IN
PORTIONS OF SOUTHEAST OREGON WILL GENERATE LOCAL BLOWING AND
DRIFTING SNOW AS WELL. A COLD FRONT WILL RACE THROUGH THE AREA THIS
EVENING WHICH WILL END THE STEADIER SNOWS...BUT SNOW SHOWERS WILL
LINGER LATE TONIGHT THROUGH WEDNESDAY FAVORING THE HIGH COUNTRY.
.LONG TERM...WEDNESDAY NIGHT THROUGH SUNDAY...NEXT SYSTEM ARRIVES
WEDNESDAY NIGHT WITH SNOW IN THE MOUNTAINS. GOOD MODEL AGREEMENT ON
TIMING WITH THIS STORM SO HAVE INCREASED POPS SIGNIFICANTLY FOR
THURSDAY. LOOKS LIKE THIS STORM STARTS AS WARM ADVECTION EVENT WITH
PRECIP FOCUSED IN THE MOUNTAINS AND GOOD OROGRAPHIC LIFT FROM STRONG
MID-LEVEL WESTERLY WINDS /50 KTS AT 700 MB/. AS UPPER TROUGH DROPS
INTO CWA THURSDAY AFTERNOON...ATMOSPHERE DESTABILIZES BRINGING
BETTER CHANCE OF PRECIP TO THE VALLEYS THURSDAY AFTERNOON/EVENING.
NEXT SYSTEM DROPS INTO THE PACIFIC NORTHWEST ON SATURDAY WITH
ANOTHER ROUND OF SNOW. MODELS STILL SHOW THIS FEATURE SPLITTING
APART AS IT MOVES INLAND...WHICH COULD CUT DOWN ON QPF AMOUNTS FOR
THE FORECAST AREA.

.AVIATION...WIDESPREAD IFR CONDITIONS IN SNOW AND LOW CEILINGS
DEVELOPING FROM ACROSS ALL OF SOUTHWEST IDAHO AND SOUTHEAST OREGON
TODAY. EXPECT IFR CONDITIONS INTO THE TREASURE VALLEY AROUND 18Z
THIS MORNING AND INTO THE MAGIC VALLEY AFTER 20Z. GUSTY
EAST-SOUTHEAST SURFACE WINDS WILL DEVELOP THIS MORNING WITH STRONG
WESTERLY WINDS ALOFT /30-50 KTS UP TO 10K FEET MSL/. CONDITIONS
IMPROVE THIS EVENING AFTER 03Z IN SOUTHEAST OREGON AND AFTER 06Z IN
SOUTHWEST IDAHO.
