AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE POCATELLO ID
145 PM MST SAT DEC 1 2007

.SHORT TERM...TONIGHT THROUGH TUESDAY.

FAIRLY ACTIVE PATTERN THROUGHOUT THE SHORT TERM WITH A HEALTHY
AMOUNT OF SNOW EXPECTED FOR THE CENTRAL MOUNTAINS...NORTHERN AND
EASTERN HIGHLANDS. LIGHT SNOW CONTINUES TO MOVE ACROSS SOUTHEAST
IDAHO THIS AFTERNOON. THIS IS DUE TO AN UPPER TROUGH THAT IS
ADVANCING THROUGH THE REGION. AMOUNTS HAVE BEEN RATHER LIGHT WITH
MOST AREAS ONLY SEEING A LIGHT DUSTING. THIS TROUGH WILL MOVE
THROUGH THE AREA TONIGHT WITH MODELS ONLY SUGGESTING LOW SNOW
CHANCES IN THE HIGH COUNTRY TONIGHT. EXPECT SKIES TO REMAIN MOSTLY
CLOUDY WITH MODELS CONTINUING TO SHOW A GOOD DEAL OF LOW LEVEL
MOISTURE HANGING AROUND STILL. ALTHOUGH THERE HAS BEEN SOME
CLEARING ACROSS NEVADA THIS AFTERNOON AND THIS MAY PROVIDE A FEW BREAKS
IN OUR AREA TONIGHT.

ON SUNDAY...WESTERLY FLOW ALOFT DEVELOPS AND A STRONG PUSH OF
PACIFIC MOISTURE WILL BE ASSOCIATED WITH IT. THIS PUSH OF MOISTURE
WILL PERSIST THROUGH SUNDAY AND SUNDAY NIGHT. ALTHOUGH THERE ARE
NO SIGNIFICANT SYSTEMS TO PROVIDE ADDITIONAL LIFT FOR SUNDAY AND
SUNDAY NIGHT...THE UPPER JET OVERHEAD ALONG WITH TOPOGRAPHICAL
LIFT AND THE ABUNDANT MOISTURE SHOULD PRODUCE GOOD QPF IN THE
CENTRAL MOUNTAINS...EASTERN AND NORTHERN HIGHLANDS. THE
ORIENTATION OF THE MOISTURE ALONG WITH DOWNSLOPE EFFECTS LEADS TO LOW
CHANCES FOR THE SNAKE VALLEY AND SOUTHERN HIGHLANDS. THE MAIN PUSH
OF MOISTURE SHOULD OCCUR LATE SUNDAY AFTERNOON THROUGH MONDAY
MORNING. DURING THIS TIME...A FOOT OF SNOW MAY BE POSSIBLE IN THE
CENTRAL MOUNTAINS ABOVE 9000FT...BELOW 9000FT AMOUNTS ARE REDUCED
TO AROUND 6 INCHES OR SO. SINCE THE CRITERIA FOR A WINTER STORM IS
9 INCHES IN 24 HOURS BELOW 9000FT...WILL NOT BE ISSUING ANY
HEADLINES WITH THIS SYSTEM AT THIS TIME.

ON MONDAY...UPPER RIDGE BEGINS TO BUILD OVER THE REGION. THIS WILL
FORCE THE PRECIPITATION NORTHWARD. ACCOMPANYING THE RIDGE WILL BE
WARMER TEMPERATURES WHICH WILL RAISE THE SNOW LEVELS TO
5000-6000FT. THE RIDGE IS EXPECTED TO FLATTEN OUT SOMEWHAT ON
MONDAY NIGHT AND TUESDAY AS A SHORTWAVE TROUGH MOVES OVER THE
AREA. THIS WILL DIRECT THE MOIST FLOW BACK SOUTHWARD ONCE
AGAIN...ALTHOUGH THE MODELS DO NOT SHOW THAT THE MOISTURE PUSH IS
AS STRONG AS IT WILL BE ON SUNDAY/SUNDAY NIGHT. TEMPERATURES ARE
EXPECTED TO BE NEAR NORMAL TONIGHT AND SUNDAY...BEFORE CLIMBING
ABOVE NORMAL FOR MONDAY AND TUESDAY.

VALLE

.LONG TERM...TUESDAY NIGHT THROUGH SATURDAY NIGHT...MODELS BEGIN TO
LOSE AGREEMENT ON PATTERN ACROSS EASTERN IDAHO AND THE WESTERN
STATES. FOR WED...GFS HAS LOW AMPLITUDE WAVE MOVING ACROSS THE AREA
WHILE ECMWF HAS A SLOWER STRONGER TROF MOVING ACROSS AFFECTING THE
AREA THROUGH EARLY THU. SECOND AND STRONGER SYSTEM PROGGED BY BOTH
CLOSING OFF TO THE WEST OF ID BY THU PM AND DROPPING TO THE
SOUTHWEST OF THE REGION. THERE IS NO MODEL AGREEMENT WHATSOEVER ON
THE TRACK OF CLOSED LOW BUT AT LEAST MODELS SHOW SOME KIND OF TROF
MOVING ACROSS THE AREA THROUGH FRI NIGHT. THE OVERALL MESSAGE IS
THAT THE PATTERN WILL REMAIN UNSETTLED WITH A SLOW COOLING
TREND...WITH REALLY NO AGREEMENT ON THE DETAILS OF HOW THIS PATTERN
WILL EVOLVE. AM EXPECTING THE MAJORITY OF PRECIP TO FALL IN THE MTNS
WITH LESSER AMTS FOR THE SNAKE PLAIN/EASTERN MAGIC VALLEY. IN TERMS
OF GRIDS...MADE MINOR TWEAKS TO THE EXTENDED FCST.

KEYES

.AVIATION...AS OF 130PM MST...STILL QUITE A BIT OF MVFR/IFR/LIFR
CONDITIONS AS -SN CONTINUES TO FALL WITH SLOW MOVING TROF STILL TO
THE WEST. WINDS HAVE PICKED UP AT KBYI/KPIH/KIDA TO AROUND 8 TO
14KTS. WE SHOULD SEE LOW CLOUDS/-SN ENDING LATER THIS EVENING AS
TROF FINALLY PUSHES THROUGH THE AREA. EXPECT MID LEVEL CLOUDS TO
REMAIN OVERNIGHT WITH MODELS/CROSS SECTIONS SHOWING POSSIBLE BKN LOW
LEVEL CLOUDS AND -SN/SNOW FLURRIES CLOSER TO SUNRISE INTO THE
MORNING HOURS. THIS WOULD CREATE MVFR/IFR CONDITIONS AT TIMES. THERE
SHOULD BE AN OVERALL BREAK IN WIDESPREAD PRECIP UNTIL LATE SUN PM AS
NEXT SYSTEM APPROACHES THE AREA.
