AREA FORECAST DISCUSSION...CORRECTED
NATIONAL WEATHER SERVICE POCATELLO ID
329 AM MST SAT DEC 3 2011

.SHORT TERM...TODAY THROUGH MONDAY. A COLD WEATHER PATTERN WILL
REMAIN IN PLACE ACROSS EASTERN IDAHO. ONE SYSTEM CONTINUES TO MOVE
SOUTHWARD AWAY FROM THE AREA THIS MORNING. SOME LINGERING LIGHT
SNOW IS EXPECTED THIS MORNING ACROSS THE SOUTHEAST CORNER BEFORE
DRIER AIR MOVES IN. THERE IS ALSO AN AREA OF FOG AND LOW CLOUDS
THAT HAS BECOME WEDGED INTO THE SOUTHERN PORTION OF THE MAGIC
VALLEY AND ADJACENT VALLEYS. THIS SHOULD BURN OFF BEFORE NOON.
OTHERWISE...PLENTY OF SUNSHINE WILL MAKE IT LOOK WARMER THAN IT
ACTUALLY WILL BE. HIGHS WILL ONLY BE IN THE 10S AND 20S...WITH THE
ONLY AREAS LIKELY TO BREAK 30 ARE IN THE VALLEYS ALONG THE UTAH
BORDER LIKE PRESTON AND SOUTH OF MALAD.

BY LATER TONIGHT AND SUNDAY...THE NEXT SYSTEM WILL BE CROSSING
EASTERN IDAHO. THIS WILL BRING ANOTHER ROUND OF VERY LIGHT SNOW
AND GUSTY WINDS. MOST AREAS SHOULD SEE AN INCH OR LESS OF SNOW
ALTHOUGH 1-2 INCHES IS POSSIBLE NEAR ISLAND PARK THROUGH SUNDAY
AFTERNOON. IT APPEARS WINDS WILL RAMP UP SUNDAY AFTERNOON AND
CONTINUE INTO SUNDAY NIGHT/MONDAY MORNING. SPEEDWISE...THEY WILL
PEAK IN THE 15-25 MPH WITH HIGHER GUSTS IN MANY LOCATIONS. THERE
COULD BE SOME ISSUES WITH BLOWING SNOW BUT IT SHOULD NOT BE A
MAJOR ONE AT THIS TIME. THE BIGGEST IMPACT WILL COME SUNDAY NIGHT
AND EARLY MONDAY AS THESE WINDS WILL COMBINE WITH COLDER AIR
FILTERING IN...PRODUCING DANGEROUSLY LOW WIND CHILLS. MANY AREAS
WILL SEE WIND CHILLS OF -5 TO -20 DURING THIS TIME.
HOWEVER...PORTIONS OF THE UPPER SNAKE PLAIN AND HIGHLANDS WILL SEE
WIND CHILLS OF -20 TO -40. WE ARE ISSUING A WIND CHILL WATCH TO
COVER THAT AREA. ANOTHER POCKET OF SIMILAR WIND CHILL VALUES IS
EXPECTED ACROSS PORTIONS OF THE CENTRAL MOUNTAINS. THIS IS
ASSOCIATED MORE WITH VERY COLD TEMPERATURES AND LIGHT WINDS. AT
THIS TIME...WE WILL NOT BE ISSUING A WIND CHILL WATCH THERE AS THE
WINDS ARE NOT GOING TO BE STRONG ENOUGH. MONDAY WILL BE DRY BUT
EVEN COLDER THAN SUNDAY WITH HIGHS STRUGGLING TO GET OUT OF THE
MID 20S IN THE WARMEST VALLEY LOCATIONS. KEYES

.LONG TERM...MONDAY NIGHT THROUGH SATURDAY.

EXTENDED FORECAST CONTINUES TO LOOK MAINLY DRY. A RIDGE WILL REMAIN
ANCHORED ALONG THE PACIFIC COAST WHICH WILL KEEP MOST OF THE SYSTEMS
NORTH OR EAST OF THE REGION. NORTHERLY FLOW WILL PERSIST ACROSS THE
AREA WITH CONTINUED COLD TEMPS.

&&

.AVIATION...SOME FOG HAS SETTLED INTO THE MAGIC VALLEY THIS MORNING.
LOW VISIBILITIES WILL BE POSSIBLE AROUND BYI FROM TIME TO TIME EARLY
THIS MORNING. OTHERWISE...VFR CONDITIONS AND RELATIVELY LIGHT WINDS
EXPECTED THROUGH THE NEXT 24 HOURS..
