ACROSS THE UPPER SNAKE HIGHLANDS...EASTERN HIGHLANDS AND THE

1242 PM MST TUE FEB 11 2014

.SHORT TERM...TONIGHT THROUGH THURSDAY NIGHT.
SIGNIFICANT PACIFIC MOISTURE SET TO MOVE INTO SOUTHEAST IDAHO
TONIGHT THROUGH THURSDAY. PACIFIC FRONTAL SYSTEM WILL MOVE ON
SHORE TONIGHT AND WARM FRONTAL BOUNDARY WILL SET UP ALONG THE
OREGON AND IDAHO BORDER WEDNESDAY. GOOD SET UP FOR HEAVY
PRECIPITATION ALONG THE WEST SLOPES OF THE CENTRAL MOUNTAINS AND
UPPER SNAKE AND CARIBOU HIGHLANDS AND IDAHO WASATCH. THIS IS A
WARM SYSTEM WITH SNOW LEVELS STARTING OUT AT AROUND 4500 FEET
TONIGHT AND RISING TO 6 THOUSAND TO AS HIGH AS 6700 FEET BY
WEDNESDAY EVENING. HAVE UPGRADED THE WATCHES TO WARNINGS AND
CONTINUED TO LIMIT TO ELEVATIONS ABOVE 6 THOUSAND FEET. HEAVIEST
SNOW WILL LIKELY BE ABOVE 7 THOUSAND FEET ELEVATION. EXPECT 8 TO
14 INCHES ABOVE 6 THOUSAND FEET WITH PRECIPITATION BECOMING ALL
RAIN BELOW THOSE LEVELS. SOME LOCAL AREAS COULD SEE UP TO 2 FEET
AT 7500 FEET OR HIGHER. STRONG WESTERLY WINDS WILL ACCOMPANY THE
SYSTEM WITH BLOWING AND DRIFTING SNOW EXPECTED ALONG MOUNTAIN
PASSES. COULD POTENTIALLY SEE FLOODING IN LOWER ELEVATIONS OF THE
WOOD RIVER REGION WHERE PRECIPITATION TURNS TO RAIN. HEAVIEST
PRECIPITATION IS EXPECTED BETWEEN 5 AM WEDNESDAY AND 5 AM THURSDAY.
PRECIPITATION SHOULD TAPER OFF THURSDAY AFTERNOON AND EVENING AS
GET A BRIEF BREAK BEFORE NEXT PACIFIC SYSTEM MOVES INTO SOUTHEAST
IDAHO FRIDAY.
GK

.LONG TERM...FRIDAY THROUGH TUESDAY. MOISTURE WILL CONTINUE TO
STREAM IN OFF THE PACIFIC AND KEEPING US UNDER GENERALLY WET AND
BREEZY CONDITIONS THROUGH THE WEEKEND. FRIDAY'S SYSTEM LOOKS TO BE
AN EVEN WARMER STORM WITH SNOW LEVELS RISING TO BETWEEN 7000-8000FT
WITH POTENTIALLY 6-12 INCHES ABOVE THOSE ELEVATIONS. THERE WILL BE
SOME BLOWING AND DRIFTING BUT WARMER TEMPERATURES WILL MITIGATE THAT
SOMEWHAT. WHAT IT WON'T HELP ALLEVIATE IS INCREASING AVALANCHE
CONCERNS. IT DOES APPEAR THAT SOME AREAS OUTSIDE OF THE CENTRAL
MOUNTAINS AND UPPER SNAKE HIGHLANDS WILL GET A BRIEF BREAK BEFORE
SUNDAY'S STORM AND COOL FRONT PUSH THROUGH EASTERN IDAHO. THAT FINAL
PUSH WILL LIKELY BE THE LOWEST RAIN/SNOW PRODUCER BUT IT WILL STILL
ADD TO THE MUCH NEEDED MOISTURE AMOUNTS WE ARE EXPECTING. ALTHOUGH
THE MODELS ARE ENSEMBLES ARE STILL A BIT CHAOTIC IN TERMS OF TIMING
THE MIDWEEK STORM...WE SHOULD SEE A DRIER PERIOD OF WEATHER FOR
EARLY NEXT WEEK.  KEYES

.AVIATION...SHOWERS AND LOWER CEILINGS ARE QUICKLY DIMINISHING OVER
MUCH OF EASTERN IDAHO THIS AFTERNOON. WE SHOULD BE VFR AT ALL SITES
UNTIL THIS EVENING AND OVERNIGHT. WE SHOULD SEE LOWER CLOUDS
REDEVELOPING AFTER DARK ACROSS AS MOISTURE INCREASES AHEAD OF OUR
NEXT STORM. WE SHOULD BE MOSTLY VFR WITH SOME LOCALIZED MVFR
CEILINGS. BETWEEN 3 AND 5AM...CONDITIONS WILL QUICKLY DETERIORATE AS
DEEP MOISTURE SURGES BACK INTO EASTERN IDAHO. WE SHOULD SEE MVFR/IFR
CONDITIONS AT ALL SITES THROUGH MOST OF TOMORROW. INITIALLY ALL
SITES WILL SEE SNOW OR A RAIN/SNOW MIX...BUT TRANSITION TO ALL RAIN
IN THE AFTERNOON. IT WILL ALSO BE BREEZY AT THE VALLEY SITES.  KEYES
