214 AM MDT MON SEP 1 2014

.SHORT TERM...LABOR DAY THROUGH WEDNESDAY. THE TAIL END OF THE
WEEKEND SYSTEM CONTINUES TO CLIP AREAS NEAR ISLAND PARK THIS
MORNING. AS THE MORNING WEARS ON...ANY CLOUDS AND SHOWERS WILL
QUICKLY EXIT TO THE EAST. WE WILL BE LEFT WITH A COOL LABOR DAY
WITH A BIT OF A BREEZE THIS AFTERNOON...ALTHOUGH IT`LL BE LESS
THAN THE PAST COUPLE. DRY CONDITIONS AND LIGHT WIND WILL MEAN A
COOL...AND FOR SOME QUITE CHILLY...MONDAY NIGHT WITH 30S AND 40S
FOR MOST OF US. HIGHER VALLEYS LIKE STANLEY AND COPPER BASIN WILL
DROP TO THE MID 20S. A QUICK REBOUND TOMORROW THOUGH AS HIGHS POP
BACK UP TO TYPICAL TEMPERATURES OF 70S TO MID 80S. ANOTHER SYSTEM
SETS UP SHOP ACROSS SOUTHERN CANADA AND THE WESTERN STATES FOR
MIDWEEK. AS THE FIRST AND MAIN PIECE OF THIS SYSTEM SWINGS ALONG
THE BORDER WEDNESDAY...THIS WILL PUSH A COLD FRONT ACROSS EASTERN
IDAHO. THIS WILL BE A MOSTLY DRY FRONT ALTHOUGH A STORM OR TWO MAY
FIRE ACROSS THE CENTRAL MOUNTAINS AND ALONG THE MONTANA BORDER. OTHERWISE...WE
WILL SEE AN INCREASE IN CLOUDS AND ANOTHER COOL...BREEZY DAY ON
WEDNESDAY. WE WILL BE BORDERLINE FOR A LAKE WIND ADVISORY.  KEYES

.LONG TERM...WEDNESDAY NIGHT THROUGH NEXT MONDAY. THE MODELS ARE
STRUGGLING A BIT AND WHAT HAPPENS WITH THE LINGERING TROUGH
ACROSS THE WEST. THE GFS IS A LOT WEAKER WITH THE NEXT WAVE TO
SWING ACROSS THE REGION FOR THURSDAY VS THE ECMWF. THE GFS IS ALSO
ALREADY CLOSING OFF THE FAR WESTERN PORTION OF THE PATTERN...AND
ALREADY PUTTING IDAHO UNDER SOUTHERLY FLOW. IF YOU LOOK AT BOTH
MODELS...THEY ARE BRINGING A SLIGHT CHANCE OF SHOWERS/STORMS TO
EASTERN LOCATIONS DESPITE THE DIFFERENCE. THE FORECAST WILL
REFLECT THIS. THESE DIFFERENCES REMAIN BEYOND THURSDAY...WITH THE
GFS MAINTAINING MOISTURE AND THE POTENTIAL FOR ISOLATED SHOWERS
AND STORMS ACROSS THE NORTH...WHILE THE ECMWF IS MOSTLY DRY EXCEPT
AROUND BEAR LAKE. IN KEEPING WITH THE IDEA OF BLENDING THE TWO
FORECASTS...WE WILL MAINTAIN A SLIGHT CHANCE OF PRECIPITATION
ACROSS THE CENTRAL AND EASTERN MOUNTAINS THROUGH THE PERIOD.
TEMPERATURES WILL REMAIN COOLER UNTIL THE WEEKEND BUT SLOWLY WARM
AFTER THAT...SIMILAR TO WHAT THE PRIOR FORECAST SHOWED.  KEYES

CLEAR. VFR THRU TONIGHT. HEDGES

.SHORT TERM...TONIGHT THROUGH TUESDAY...RESIDUAL MOISTURE
RESIDING IN A W-NW FLOW WITH DAYTIME HEATING PROMOTED SCATTERED
CUMULUS CLOUDS ACROSS THE NORTHERN PORTIONS OF SOUTHEAST OREGON
AND SOUTHWEST IDAHO THIS AFTERNOON. THE CLOUDS HAVE SHOWN LITTLE
VERTICAL EXTENT AS THE AIR MASS HAS STABILIZED SINCE
YESTERDAY...THUS WE ARE NOT EXPECTING ANY SHOWERS WITH THE CLOUDS.
THE CLOUDS WILL DIMINISH OVERNIGHT WITH CLEAR SKIES EXPECTED LATE.
GUSTY W-NW WINDS WILL ALSO DIMINISH THIS EVENING. THE COMBINATION
OF CLEARING SKIES AND LIGHT WINDS WILL BRING A COOL START TO LABOR
DAY. LABOR DAY THROUGH TUESDAY...FLOW ALOFT WILL TURN W-SWLY AHEAD
OF AN UPPER TROUGH AND COLD FRONT WHICH WILL MOVE INTO THE PACIFIC
NORTHWEST. THIS WILL RESULT IN A WARMING TREND...ALONG WITH MOSTLY
CLEAR SKIES AND LIGHT WINDS. HIGHS ON TUESDAY WILL BE NEAR TO
SLIGHTLY ABOVE NORMAL.

.LONG TERM...TUESDAY NIGHT THROUGH FRIDAY...FAIRLY GOOD AGREEMENT
IN MODELS THAT A DRY COLD FRONT WILL PUSH THROUGH THE AREA TUESDAY
NIGHT. THIS IN RESPONSE TO UPPER LEVEL TROUGH THAT MOVES FROM NEAR
VANCOUVER ISLAND ON TUESDAY NIGHT...TO NORTH DAKOTA BY THURSDAY
MORNING. TROUGH LOOKS FAR ENOUGH AWAY THAT MOISTURE WILL BE NORTH
OF THE AREA...AND WE HAVE REMOVED MENTION OF PRECIP DURING THE
PERIOD. MOST NOTICEABLE WILL BE TEMPERATURES ABOUT 10 DEGREES
BELOW NORMAL ON WEDNESDAY BEHIND THE FRONT. REMNANTS OF THE TROUGH
JUST LINGER OVER THE AREA THROUGH FRIDAY...WITH A PIECE DEEPENING
OFF THE CALIFORNIA COAST...WHICH MEANS THAT TEMPERATURES WILL BE
SLOW TO RECOVER...AND WILL STILL BE ABOUT 5 DEGREES BELOW NORMAL
BY FRIDAY.

FRIDAY NIGHT THROUGH SUNDAY...DRY NORTHWESTERLY WINDS WILL BE THE
PREDOMINANT FLOW IN OUR REGION AS THE UPPER LEVEL TROUGH MOVES TO
THE EAST. THE WARMING TREND WILL CONTINUE THROUGH THE WEEKEND AS
THE ATMOSPHERIC PRESSURE BUILDS AND DRY CONDITIONS REMAIN DUE TO
LOW MOISTURE TRANSPORT.

.SHORT TERM...STRONG SHORT WAVE TROUGH AND ASSOCIATED SURFACE COLD
FRONT MOVED THROUGH IDAHO ZONES SATURDAY EVENING WITH SHOWERS
THUNDERSTORMS AND GUSTY WINDS.  MAIN UPPER TROUGH MOVING RAPIDLY
EAST INTO THE PLAINS STATES TODAY WITH DRIER AND COOLER NWLY FLOW
ALOFT INTO OUR CWA.  ERN VALLEY COUNTY/ID STILL HAS A CHANCE OF
LIGHT RAIN SHOWERS TODAY BUT THE REST OF OUR CWA WILL BE DRY.
BREEZY POST-FRONTAL WESTERLY WINDS IN THE MAGIC VALLEY AND NEARBY
ZONES TODAY.  MOSTLY CLEAR AND COOLER TONIGHT WITH DIMINISHING
WINDS.  AIR MASS WILL NOT BE DRY ENOUGH FOR MAXUMIMUM RADIATIONAL
COOLING BUT IT WILL DEFINITELY BE COOLER THAN THIS MORNING WITH MIN
TEMPS IN THE 30S AT MOUNTAINS STATIONS AND 40S TO LOWER 50S IN THE
VALLEYS.  HIGHS MONDAY WILL BE ABOUT 2 DEGS WARMER THAN TODAY ALONG
WITH LESS WIND.

.LONG TERM...MONDAY NIGHT THROUGH SATURDAY...WESTERLY FLOW WILL
DEVELOP OVER THE REGION ON TUESDAY AS THE NEXT UPPER LEVEL TROUGH
CONTINUES TO DIG SOUTH ALONG THE CANADIAN WEST COAST.  VERY LITTLE
MOISTURE WITH THIS SYSTEM SO EXPECT DRY CONDITIONS TO CONTINUE
OVER THE FORECAST AREA TUESDAY ALONG WITH TEMPERATURES WARMING BACK
TO NEAR NORMAL.  LATEST MODEL RUNS CONTINUE TO SPLIT THIS SYSTEM AS
IT MOVES TO THE EAST...WITH THE ECMWF THE FASTEST IN MOVING THE
NORTHERN SECTION EAST ALONG THE CANADIAN BORDER.  00Z RUN OF THE GFS
MORE IN LINE WITH THE PREVIOUS ECMWF...BUT WILL CONTINUE TO TREND
TOWARD THE STRONGER AND FASTER ECMWF DUE TO BETTER RUN TO RUN
CONSISTENCY COMPARED TO THE GFS.  GOING WITH THE TIMING OF THE
ECMWF...WILL SEE A DRY COLD FRONT MOVE OVER THE FORECAST AREA
TUESDAY NIGHT INTO WEDNESDAY WITH TEMPERATURES COOLING TO A FEW
DEGREES BELOW NORMAL.  AS THE NORTHERN SECTION OF THE TROUGH MOVES

WET SIDE...ISLAND PARK HAS RECEIVED 0.29 INCHES RAIN IN THE PAST 6
HOURS...ABOUT .08 INCHES AT ARCO. THE TROUGH AXIS OF THE SECOND WAVE
SHOULD CLEAR IDAHO FALLS CLOSE TO SUNRISE SUNDAY...LEAVING A SLIGHT
CHANCE OF SHOWERS IN THE AFTERNOON NORTH AND EAST OF IDAHO FALLS.
PRESSURE GRADIENT WILL KEEP WINDS ON THE BREEZY SIDE BUT LESS THAN
TODAY...PERHAPS 10-15 MPH GUST 25 MPH. THE FAIR SHOULD AVOID SHOWERS
OR THUNDERSTORMS THE REMAINDER OF SUNDAY. HIGH PRESSURE RIDGE MOVES
IN MONDAY AND TUESDAY FOR DRY CONDITIONS AND TEMPERATURES REBOUNDING
A FEW DEGREES...WINDS EASE OFF A LITTLE MORE. MODELS ARE STILL
WRESTLING WITH THE NEXT TROUGH WEDNESDAY AND THURSDAY. GFS WANTS TO
SPLIT THE FLOW PATTERN...TRYING TO CUT OFF A CIRCULATION NEAR
NORTHERN CALIFORNIA...WHILE OTHER MODELS FAVOR THE TROUGH STAYING
CONSOLIDATED AND LIMITING MOST OF THE PRECIPITATION NORTHWARD OF
THIS AREA AS IT PASSES. KEEPING A SLIGHT CHANCE OF SHOWERS IN THE
FORECAST...MAINLY ON THURSDAY FOR NOW. RS

.DISCUSSION...THE LOW PRESSURE TROUGH MOVING THROUGH THE PACIFIC
NORTHWEST HAS AT LEAST TWO EMBEDDED WAVES IN IT. THE FIRST IS MAKING
ITS WAY THROUGH THE UPPER SNAKE PLAIN THIS AFTERNOON. A FAIR AMOUNT
OF LIGHTNING WITH THE THUNDERSTORMS WHICH SO FAR HAVE BEEN LIMITED
TO AREAS NORTH OF ARCO. A COUPLE OF CELLS HAVE TRIED TO DEVELOP A
BIT FURTHER SOUTH BUT SO FAR HAVE BEEN ON THE WEEK SIDE. THIS WILL BE
A WATCH AN SEE THE NEXT COUPLE OF HOURS FOR THE STATE FAIR IN
BLACKFOOT. THERE WILL BE A FEW HOURS BREAK BETWEEN THIS WAVE AND THE
LEADING EDGE OF THE NEXT WAVE MOVING INTO OREGON RIGHT NOW. THE
LEADING EDGE OF THAT ACTIVITY COULD REACH CLOSE TO BLACKFOOT ABOUT

COLD FRONT CURRENTLY SITUATED NEAR THE PACIFIC NORTHWEST COAST
WILL MOVE THROUGH THE AREA THIS AFTERNOON AND TONIGHT. THIS WILL
BRING ANOTHER ROUND OF SHOWERS AND ISOLATED THUNDERSTORMS...WITH

SHORT TERM...SURFACE COLD FRONT PASSING THROUGH IDAHO ZONES THESE
PRE-DAWN HOURS.  SCATTERED SHOWERS AND ISOLATED THUNDERSTORMS HAVE
ACCOMPANIED FROPA. COOLER AND MORE STABLE POST-FRONTAL WLY FLOW
WILL COME IN TODAY UNDER INCOMING NORTH PACIFIC UPPER TROUGH.
EMBEDDED SHORT WAVE TROUGH WILL INCREASE THE CHANCE OF SHOWERS IN
NRN ZONES TONIGHT...THEN DRIER BUT CONTINUED COOL NWLY FLOW ALOFT
IN ALL ZONES SATURDAY AS THE MAIN TROUGH GOES RAPIDLY INTO THE
HIGH PLAINS.

ALOFT WILL REMAIN OVER THE REGION SUNDAY NIGHT AND LABOR DAY WITH
TEMPERATURES A FEW DEGREES BELOW NORMAL.  THE FLOW ALOFT WILL SHIFT
TO THE WEST ON TUESDAY THEN TO THE SOUTHWEST ON WEDNESDAY AHEAD OF
AN UPPER TROUGH THAT IS DIGGING SOUTH OVER BRITISH COLUMBIA.  THIS
UPPER LEVEL TROUGH WILL BRING TEMPERATURES BACK TO NEAR NORMAL...BUT
ANY MOISTURE AND PRECIPITATION WILL REMAIN TO THE NORTH OF THE
FORECAST AREA AS THE AXIS OF THE TROUGH CONTINUES TO MOVE TO THE
SOUTHEAST.  AS THE AXIS OF THIS TROUGH MOVES OVER THE FORECAST AREA
WILL SEE A COLD FRONT MOVE OVER THE REGION TUESDAY NIGHT FOR COOLER
TEMPERATURES ON WEDNESDAY.  WEDNESDAY NIGHT THROUGH FRIDAY MODELS
DIFFER ON HOW QUICKLY THE UPPER LEVEL TROUGH WILL MOVE TO THE
