AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE POCATELLO ID
130 PM MDT FRI OCT 7 2011

.DISCUSSION...TONIGHT THROUGH NEXT FRIDAY. THE LATEST REGIONAL RADAR
LOOP WAS SHOWING DIMINISHING RADAR RETURNS ACROSS SE IDAHO EARLY
THIS AFTERNOON WHILE SCT SHOWERS CONTINUED TO LINGER ACROSS THE SE
HIGHLANDS. FURTHER UPSTREAM...RADAR AND SATELLITE IMAGERY SHOWED THE
NEXT PAC SHORT-WAVE DIGGING SE INTO THE IDAHO PANHANDLE WITH
INCREASING RADAR RETURNS ACROSS WRN MONTANA. THE 12Z NAM/GFS WERE
BOTH SHOWING INCREASING PRECIPITATION POTENTIAL ACROSS THE SNAKE
PLAIN AND NE DIVIDE ZONES THIS EVENING AS THIS WAVE DIGS SHARPLY SE
OVERNIGHT. LIKELY POPS AND 1 TO 2 INCHES OF SNOW ACCUMULATION ACROSS
THE ERN HIGHLANDS AND SNAKE PLAIN BENCHES WERE DEPICTED TO COVER
THIS INCOMING WAVE THIS EVENING. COUNTING OF RESIDUAL CLOUD COVER
SATURDAY MORNING TO STAVE OFF A HARD FREEZE...BUT IT DOES LOOK LIKE
WE COULD GET COLD ENOUGH LATE TONIGHT/SATURDAY MORNING TO SUPPORT AT
LEAST A FROST ADVISORY IN THE UPPER VALLEY.  BY SATURDAY
AFTERNOON...A SHORT-WAVE RIDGE IS EXPECTED TO SHIFT EAST INTO IDAHO
AS A CUT-OFF LOW CIRCULATION EJECTS NNE THROUGH COLORADO/WYOMING
WITH WRAP AROUND MOISTURE PROVIDING A SLIGHT CHANCE MENTION OF
PRECIPITATION ALONG THE WYOMING BORDER. IF THE RIDGE IS SLOWER AND
THE EJECTING LOW TRACKS FURTHER WEST THIS MAY NEED TO BE ADJUSTED
HIGHER. SKIES ARE EXPECTED TO CLEAR WITH A DRIER AIRMASS OVERHEAD
EARLY SUNDAY MORNING WITH A GOOD POTENTIAL FOR A HARD FREEZE IN THE
SNAKE PLAIN ZONES AND AT LEAST A FROST ADVISORY IN THE ERN MAGIC
VALLEY.  BY SUNDAY AFTERNOON WE TRANSITION INTO AN UNSETTLED WEST
FLOW WITH EMBEDDED PAC WAVES EXPECTED TO MOVE ONSHORE CLIPPING THE
REGION MONDAY NIGHT/TUESDAY. BY WEDNESDAY...A SHALLOW RIDGE BUILDS
OVER THE GREAT BASIN WHICH MAY HELP TO DEFLECT SOME OF THE WEAKER
PAC WAVES NORTH INTO CANADA. BOTH THE GFS/ECMWF SHOW A MORE
SUBSTANTIAL PAC TROUGH REACHING THE NW COAST AROUND FRIDAY OR
SATURDAY WITH VARYING DEGREES OF STRENGTH AND SPEED BETWEEN THE
MODELS. THUS HAVE GENERALLY MAINTAINED LOW END CHANCE MENTION OF
PRECIPITATION LEADING INTO NEXT WEEKEND. HUSTON
&&

 .AVIATION...AREA TERMINALS STILL BEING IMPACTED BY WRAP-AROUND
MOISTURE FROM A RECENT STORM SYSTEM THAT WENT THROUGH. AS A
RESULT...CEILINGS HAVE BEEN IFR TO MVFR OVER MUCH OF THE AREA. SNOW
HAS LARGELY TAPERED OFF...BUT SOME PATCHES OF RAIN CAN BE SEEN ON
RADAR THIS AFTERNOON. ANOTHER IMPULSE OF UPPER LEVEL ENERGY WILL
MOVE THROUGH TONIGHT KEEPING CHANCES FOR RAIN IN THE FORECAST
THROUGH TOMORROW MORNING.  HINSBERGER
&&

.FIRE WEATHER...EXPECT CLOUDS TO LINGER THROUGH TONIGHT AND INTO
TOMORROW MORNING AS A MINOR DISTURBANCE PASSES THROUGH THE AREA
TONIGHT. RIDGING WILL MOVE ACROSS IDAHO SUNDAY BRINGING DRIER
WEATHER...BUT ANOTHER DISTURBANCE WILL APPROACH THE REGION ON MONDAY
NIGHT. A BROAD UPPER LEVEL RIDGE WILL MOVE INTO THE AREA AFTER
MID-WEEK KEEPING MAINLY DRY CONDITIONS OVER IDAHO. HINSBERGER
