AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BOISE ID
856 PM MDT SUN JUN 17 2012

.DISCUSSION...WIND EVENT HAS NOT DEVELOPED IN SOUTHERN IDAHO AS
EXPECTED COLD FRONT HAS BEEN DELAYED.  AT 8 PM MDT TEMPERATURES WERE
STILL 85 TO 90 DEGREES IN THE TREASURE AND MAGIC VALLEYS AND NEAR 70
DEGREES IN THE WEST CENTRAL IDAHO MOUNTAINS.  SURFACE PRESSURE WAS
STILL FALLING AT MOST SITES.  COLD FRONT SHOULD LOWER TEMPERATURES
AT LEAST 10 DEGREES AND BE FOLLOWED BY PRESSURE RISE.  THE FRONT IS
HARD TO LOCATE DUE TO LACK OF CLOUDS BUT WITH JET STREAM CONTINUING
TO SAG SOUTH THE FRONT WILL COME THROUGH LATER TONIGHT.  AT THAT
TIME WEST/NORTHWEST WINDS SHOULD BRIEFLY INCREASE.  A SECOND SURGE
OF COOL AIR WILL COME IN MONDAY AND WINDS WILL INCREASE IN THE
AFTERNOON TO SPEEDS PROBABLY STRONGER THAN TODAY/S WINDS.  REST OF
CURRENT FORECAST STILL LOOKS GOOD SHOWING DRASTIC COOLING MONDAY AND
TUESDAY AND SHOWERS ONLY IN FAR NORTHERN CWA.

&&

.AVIATION...VFR THROUGH MONDAY. WESTERLY WINDS SURFACE AND ALOFT.
SPEEDS AT THE SURFACE UP TO 30 KTS THIS EVENING WILL DIMINISH
SHORTLY AFTER SUNSET. WINDS INCREASE AGAIN LATE MONDAY MORNING WITH
SPEEDS UP TO 40 KTS IN OPEN VALLEYS. WINDS ALOFT ARE 30-40 KTS
THROUGH 10K FEET MSL ON MONDAY. MID-LEVEL CEILINGS WILL DEVELOP
ACROSS EAST-CENTRAL OREGON AND WEST-CENTRAL IDAHO MONDAY AFTERNOON
WITH BASES OF 9-10K FEET MSL.

&&

.PREV DISCUSSION...
SHORT TERM...TONIGHT THROUGH TUESDAY...BIG CHANGE IN TEMPERATURE
REGIME IS SET FOR THE FORECAST AREA COMMENCING TONIGHT AND
CONTINUING THROUGH TUESDAY. A DRY COLD FRONT WILL MOVE THROUGH THE
AREA THIS EVENING PUSHING HIGH TEMPERATURES IN THE 80S AND 90S TODAY
ALL THE WAY DOWN INTO THE 60S AND 70S FOR TOMORROW AND TUESDAY.
FRONT IS MOISTURE STARVED WITH ONLY LIMITED MID LEVEL MOISTURE NOTED
NORTH OF BOISE AND THE SNAKE PLAIN. LEFT A SMALL AREA OF POSSIBLE
CONVECTION THIS EVENING AND MONDAY AFTERNOON WELL TO THE NORTH NEAR
THE SALMON RIVER AND ADJACENT TO MISSOULA FORECAST AREA. MAIN STORY
FOR THE SHORT TERM FORECAST IS WIND...COOLER TEMPERATURES AND RED
FLAG CONDITIONS FOR FIRE WEATHER. A WIND ADVISORY REMAINS IN EFFECT
BRIEFLY THIS EVENING POST COLD FRONT AS THE CORE OF THE STRONGER JET
LEVEL WINDS SAG SOUTHWARD INTO THE SNAKE VALLEY. ADVISORY THIS
EVENING LOOKS MARGINAL AND WILL BE CENTERED MAINLY FROM BOISE
EASTWARD TO TWIN FALLS. BETTER SUPPORT FOR A WIDER COVERAGE AND
STRONGER WIND ADVISORY MONDAY AS UPPER LEVEL WINDS ALIGN...SURFACE
PRESSURE GRADIENT INCREASES AND COOL ADVECTION IS STRONGEST BEHIND
THE COLD FRONT.

LONG TERM...TUESDAY NIGHT THROUGH SUNDAY...LATEST MODELS SHOW A
PATTERN SIMILAR TO THAT OF EARLIER RUNS WITH TRANSITION INTO A HIGH
AMPLITUDE PATTERN EARLY IN THE PERIOD AS A VERY WARM UPPER LEVEL
RIDGE BUILDS OVER THE SOUTHERN ROCKIES/SOUTHERN AND CENTRAL PLAINS
WHILE A COOL UPPER LEVEL TROUGH TAKES UP RESIDENCE OFF THE NORTHWEST
COAST. THE MOST INTERESTING PART OF THE FORECAST CONTINUES TO BE
NEXT WEEKEND AND EARLY NEXT WEEK...WHEN MODELS DIFFER IN PLACEMENT
OF THESE TWO FEATURES AND RUN TO RUN CONSISTENCY HAS BEEN BELOW
AVERAGE. LOOKING AT NEXT SUNDAY...THE NOGAPS WANTS TO BRING THE
TROUGH INLAND AS THE RIDGE RETREATS EAST OVER THE MISSISSIPPI
VALLEY...A PATTERN REMINISCENT OF JULY 4 AND 5 1986 WHEN BOTH MAX
AND MIN LOW TEMPERATURE RECORDS WERE SET AT BOISE. OTHER MODELS
INCLUDING BOTH GFS AND ECM ENSEMBLE MEANS KEEP THE TROUGH OFFSHORE.
GFS ENSEMBLE MEMBERS SHOW AS MUCH SPREAD. SO DUE TO UNCERTAINTY WE
ARE GOING WITH A MODEL BLEND FOR NEXT WEEKEND...WITH MAX
TEMPERATURES SLIGHTLY BELOW NORMAL AND A CHANCE OF THUNDERSTORMS
OVER OUR NORTHERN AND WESTERN ZONES. FOR THURSDAY AND FRIDAY
TEMPERATURES WARM TO 5-8 DEGREES ABOVE NORMAL AS THE RIDGE INITIALLY
BUILDS AND THE TROUGH IS STILL WEST OF THE QUEEN CHARLOTTE AND
VANCOUVER ISLANDS.
