AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE POCATELLO ID
200 PM MDT SAT AUG 18 2012

.DISCUSSION...TONIGHT THROUGH NEXT SATURDAY. THE LATEST SATELLITE
IMAGERY WAS SHOWING A LOW PRESSURE SYSTEM LIFTING NE TOWARD VC
ISLAND. THE MODELS CONTINUE TO SHOW EJECTING SHORT-WAVE ENERGY
LIFTING OUT OF THE BASE OF THIS TROUGH ACROSS OREGON TONIGHT AND SRN
IDAHO SUNDAY. THE BEST DYNAMICS IS EXPECTED ACROSS THE CNTRL
MOUNTAINS IN THE RIGHT REAR QUAD OF AN EXITING JET SEGMENT AND
CLEARING ON THE BACK EDGE OF THE ASSOCIATED CLOUD MASS MOVING
THROUGH IN THE MORNING. FURTHER SOUTH NEAR THE UTAH BORDER...THE
ATMOSPHERE REMAINS RELATIVELY STABLE AND SHIELDED FOR A GOOD PORTION
OF THE DAY BY CLOUDS...THUS THE POTENTIAL FOR THUNDERSTORM ACTIVITY
IS EXPECTED TO BE LOWER ESPECIALLY IN THE ABSENCE OF ANY DRIVING
DYNAMICAL FEATURE. THIS INITIAL WAVE EXITS EAST OF THE REGION SUNDAY
NIGHT AS THE RIDGE REBOUNDS ACROSS THE GREAT BASIN MONDAY. RESIDUAL
MOISTURE COUPLED WITH DIURNAL HEATING SHOULD BE ENOUGH TO PRODUCE
ISOLATED THUNDERSTORMS OVER THE MOUNTAINS MONDAY AFTERNOON WHILE THE
UPPER TROUGH OFF THE NW COAST GATHERS ITSELF FOR A FINAL PUSH INLAND
TUESDAY. THE GFS AND ECMWF REMAIN AT ODDS WITH REGARDS TO THE
OVERALL STRENGTH OF THE INCOMING WAVE AND AT THIS TIME A MIDDLE OF
THE ROAD APPROACH SEEMS MOST APPROPRIATE. THUS A BROAD BRUSH MENTION
OF SCATTERED SHOWERS AND THUNDERSTORMS REMAINS IN THE FORECAST
TUESDAY AFTERNOON/NIGHT AS THE TROUGH WORKS THROUGH THE REGION. A
GENERALLY DRY AND STABLE WEST FLOW FOLLOWS WEDNESDAY BUT THEN THE
MODELS DIVERGE ONCE AGAIN AS THE GFS GENERALLY REMAINS DRY
THROUGHOUT THE REMAINDER OF THE FORECAST PERIOD AND THE ECMWF SHOWS
A SUB-TROPICAL PUSH FROM THE SOUTH AHEAD OF A VERY WEAK LOW
CIRCULATION THAT MIGRATES INLAND ACROSS NEVADA/UTAH THURSDAY/FRIDAY.
HAVE MAINTAINED A SLIGHT CHANCE MENTION OF THUNDERSTORMS THROUGHOUT
THE REMAINDER OF THE FORECAST TO ACCOUNT FOR THE POOLING MOISTURE TO
OUR SOUTH. STATISTICAL GUIDANCE WAS SHOWING MODERATING TEMPERATURES
MONDAY BEHIND THE INITIAL WAVE AND THEN A MUCH MORE WELCOME DROP
WEDNESDAY/THURSDAY BEHIND THE SECOND WAVE. HUSTON
&&

.AVIATION...SMOKE WILL CONTINUE TO BE THE MAIN ISSUE FOR THIS
EVENING AS HIGH PRESSURE CONTINUES.  MAIN IMPACT IS TO THE CENTRAL
MOUNTAINS AND KSUN.  OTHERWISE WILL SEE INCREASING CLOUD COVER AFTER
MIDNIGHT AS A SHORTWAVE FEATURE SHIFTS EAST AND BRINGS MONSOON
MOISTURE INTO EAST IDAHO FOR SUNDAY.  THREAT OF SHOWERS AND
THUNDERSTORMS FOR SUNDAY AFTERNOON AND EVENING AS THIS SHORTWAVE
MOVES ACROSS THE AREA.  THIS MAY BRING A BIT OF RELIEF FOR SMOKEY
CONDITIONS. DSH
&&

.FIRE WEATHER...HIGH PRESSURE WILL SHIFT EAST AND MONSOON MOISTURE
WILL MOVE OVER THE REGION AS UPPER FLOW BECOMES SOUTHWESTERLY. AN
UPPER LEVEL SHORTWAVE WILL MOVE UP THROUGH THE SOUTHWEST FLOW SUNDAY
AFTERNOON BRINGING INCREASED CLOUD COVER.  EXPECT DEVELOPMENT OF
AFTERNOON AND EVENING SHOWERS AND THUNDERSTORMS...MAINLY OVER THE
CENTRAL MOUNTAINS AND ALONG THE MONTANA DIVIDE WITH THIS FEATURE.
THUNDERSTORM COVERAGE WILL BE SUFFICIENT IN ZONES 475 476 477 FOR A
RED FLAG WARNING.  ENOUGH RESIDUAL MOISTURE AND INSTABILITY WILL
REMAIN OVER THE AREA ON MONDAY FOR DEVELOPMENT OF ISOLATED SHOWERS
AND THUNDERSTORMS OVER ELEVATED TERRAIN. DSH
&&

.AIR STAGNATION...HIGH PRESSURE OVERHEAD TODAY WILL KEEP SMOKE
SETTLED IN ACROSS EASTERN IDAHO. AIR QUALITY ALERTS REMAIN IN PLACE
THROUGH THE WEEKEND FOR THE CENTRAL MOUNTAINS DUE TO THE CLOSE
PROXIMITY OF THE ONGOING FIRES. WE MIGHT SEE A LITTLE BIT OF RELIEF
SUNDAY AS A WEAK SYSTEM MOVES THROUGH THE REGION. KEYES/HUSTON

HAZARDOUS WEATHER OUTLOOK

CACHE VALLEY/IDAHO PORTION-WASATCH MOUNTAINS/IDAHO PORTION-
BIG AND LITTLE WOOD RIVER REGION-LOST RIVER/PAHSIMEROI-
309 AM MDT SAT AUG 18 2012

THIS HAZARDOUS WEATHER OUTLOOK IS FOR EASTERN IDAHO.

.DAY ONE...TODAY AND TONIGHT

HIGH PRESSURE WILL LEAD TO LIGHT WINDS AND STRONGER INVERSIONS.
THIS WILL KEEP KEEP AIR QUALITY POOR ESPECIALLY IN THE CENTRAL
MOUNTAINS DUE TO SMOKE. LIMITED MOISTURE MOVES INTO WESTERN AREAS
OVERNIGHT...BUT ANY THREAT OF SHOWERS AND STORMS WILL BE LESS THAN
10 PERCENT.

.DAYS TWO THROUGH SEVEN...SUNDAY THROUGH FRIDAY

MONSOON MOISTURE WORKS EAST INTO IDAHO TOMORROW FOR AN INCREASING
CHANCE OF SHOWERS AND THUNDERSTORMS. MANY STORMS WILL PRODUCE
LIGHT RAIN AND GUSTY WINDS...HOWEVER STRONGER STORMS COULD PRODUCE
LOCALLY HEAVY RAINFALL. A FIRE WEATHER WATCH IS IN EFFECT FOR
SUNDAY AFTERNOON AND EVENING FOR THE CENTRAL MOUNTAINS WHERE THE
HIGHEST STORM THREAT EXISTS.

ANOTHER STORM MOVES ACROSS IDAHO ON TUESDAY WITH A DECENT CHANCE
OF SHOWERS AND THUNDERSTORMS AREAWIDE. WE WILL BE WATCHING FOR
SIGNS FOR IMPROVEMENT IN AIR QUALITY. THIS MAY HAPPEN ON SUNDAY
FOR A FEW HOURS. THE BEST CHANCE OF SEEING IMPROVEMENT WOULD BE
LATER NEXT WEEK AS WINDS MIGHT PUSH THE SMOKE INTO MONTANA.

.SPOTTER INFORMATION STATEMENT...

WE ASK TRAINED SPOTTERS AND CITIZENS TO REPORT SIGNIFICANT
WEATHER CONDITIONS WHEN IT IS SAFE TO DO SO. THESE CONDITIONS MAY
INCLUDE HAIL...TORNADOES...STRONG WIND...DUST STORMS...SNOWFALL...
