AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE POCATELLO ID
327 AM MST TUE DEC 27 2011

.SHORT TERM...TODAY THROUGH THURSDAY. WE WILL BE DEALING WITH A
WEAK SYSTEM MOVING ACROSS EASTERN IDAHO TODAY. THIS ONE IS BRINGING
AN INCREASE IN CLOUDS WITH SOME VERY LIGHT SNOW MAINLY ACROSS THE
CENTRAL MOUNTAINS AND UPPER SNAKE HIGHLANDS. WE WILL BE A LITTLE
WARMER TODAY...WITH PLENTY OF 30S AND 40S TO GO AROUND. THE ONLY
PLACE THAT SHOULD REMAIN ON THE COOL SIDE WILL BE ACROSS PORTIONS
OF THE UPPER SNAKE PLAIN AND HIGHLANDS WHERE HIGHS WILL REMAIN IN
THE 25-35 DEGREE RANGE.

THE REST OF THE SHORT TERM PERIOD IS STILL EXPECTED TO BE WET AND
MUCH WARMER. FOR WEDNESDAY AND THURSDAY...SNOW LEVELS WILL BE
RISING TO THE 6000-7500FT RANGE OVER MUCH OF OUR SIDE OF THE
STATE. THIS MEANS MANY LOWER VALLEYS WILL SEE LITTLE SNOW IF AT
ALL...MEANING THE SNAKE PLAIN AND THE SOUTHERN HIGHLAND VALLEYS
SHOULD BE RAIN EVEN AT NIGHT. IT WILL ALSO BE WINDY ESPECIALLY AT
HIGHEST ELEVATIONS. DESPITE THIS BEING A WETTER SNOWFALL IN THE
MOUNTAINS...WINDS WILL BE STRONG ENOUGH AT TIMES TO CREATE PERIODS
OF BLOWING/DRIFTING SNOW. RIGHT NOW...THE STRONGEST PERIOD OF
PRECIPITATION WILL BE DELAYED UNTIL WEDNESDAY AFTERNOON AND
CONTINUE THROUGH MOST OF THURSDAY. WITH AVERY STRONG WESTERLY
FLOW...THE HIGHEST AMOUNTS WILL FALL AT OR ABOVE 7000FT ACROSS
WESTERN PORTIONS OF THE CENTRAL MOUNTAINS...UPPER SNAKE HIGHLANDS
AND NORTHERN PORTIONS OF THE CARIBOU MOUNTAINS. THOSE AREAS ARE
NOW UNDER A WINTER STORM WARNING THROUGH THURSDAY AFTERNOON WITH
15-25 INCHES OF SNOW FORECAST. WITH A LOT MORE SNOW POSSIBLE IN
THE FIRST 24 HOURS OF THE EXTENDED PERIOD...THE WARNING QUITE
POSSIBLY COULD BE EXTENDED AT SOME POINT TO COVER THAT. THE REST
OF OUR MOUNTAIN LOCATIONS WILL BE QUITE LIMITED DUE TO DOWNSLOPE
CONDITIONS AND THOSE WARMER TEMPERATURES. HIGHS BOTH DAYS WILL TOP
OUT IN THE 40S TO LOWER 50S FOR LOWER ELEVATIONS. WE COULD BE
FLIRTING WITH RECORD TEMPERATURES ESPECIALLY THURSDAY AT
BURLEY...POCATELLO AND IDAHO FALLS. IT IS POSSIBLE WE COULD COME
CLOSE TO RECORD NUMBERS EVEN AT STANLEY AS THEY WILL BE JUMPING
WELL INTO THE 30S. LOWS WILL BY THURSDAY MORNING WILL BE ONLY IN
THE MID 20S TO MID 30S FOR MOST EVERYONE. WITH DOWNSLOPE WINDS
ALONG THE INTERSTATE CORRIDOR FROM BURLEY UP THROUGH
BLACKFOOT...IT MAY NEVER GET COLDER THAN 40 DURING THAT TIME. KEYES

.LONG TERM...THURSDAY NIGHT THROUGH TUESDAY.

MOIST ZONAL FLOW IS EXPECTED TO PERSIST THROUGH FRIDAY NIGHT. SNOW
LEVELS WILL REMAIN HIGH DURING THIS TIME...6500 TO 7000 FEET AND
MAYBE HIGHER. ELEVATIONS ABOVE 7000 FEET COULD SEE 1 TO 3 FEET OF
SNOW BY THE END OF THE WEEK. THIS FLOW WILL COME TO AN END BY THE
WEEKEND WITH A RIDGE DEVELOPING OVER THE AREA AND PERSISTING INTO
EARLY NEXT WEEK.

VALLE

&&

.AVIATION...A WEAK SHORTWAVE IS EXPECTED TO PASS THROUGH THE REGION
TODAY. MOST OF THE PRECIPITATION WILL BE IN THE MOUNTAINS AND
HIGHLANDS. A FEW SHOWERS COULD BE CLOSE ENOUGH TO TAF SITES TO
JUSTIFY VC AND MVFR CEILINGS TODAY. CLOUDY CONDITIONS WILL PERSIST
INTO THE NIGHT...ALTHOUGH CEILINGS ARE EXPECTED TO LIFT TO VFR AFTER
THE PASSAGE OF THE TROUGH.
