AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BOISE ID
900 AM MDT SUN JUN 3 2012

.DISCUSSION...TREMENDOUS WX CHANGE IS EXPECTED TO BEGIN IN OREGON
MONDAY AFTERNOON AND SWRN IDAHO MONDAY EVENING AS A VERY STRONG
COLD FRONT MOVES THROUGH.  NOT ONLY WILL THE FRONT HAVE AN INTENSE
THERMAL GRADIENT BUT IT WILL ALSO BE MOVING QUICKLY AS THE
SUPPORTING NEGATIVE-TILT PACIFIC UPPER TOUGH IS FORCED INLAND
BY ANOTHER TROUGH FARTHER OUT IN THE PACIFIC.  IT IS RARE THAT A
HIGH-AMPLITUDE EVENT ALSO MOVES QUICKLY BUT IT WILL THIS TIME.
THE RESULT WILL BE A VERY STRONG FRONTAL PASSAGE THAT WILL ALSO
INCLUDE THUNDERSTORMS...ESPECIALLY ON THE IDAHO SIDE.  LATEST MODELS
PLACE THE FRONT IN ERN OREGON AT 4 PM PDT MONDAY...SWRN IDAHO 7-8 PM
MDT MONDAY...AND SCENTRL IDAHO AROUND 10 PM MDT MONDAY.  THESE TIMES
ARE 1-2 HOURS LATER THAN PREVIOUSLY FORECAST BUT MODELS SEEM TO BE
FINALLY SETTLING IN ON THE TIMING.  SURFACE PRESSURE GRADIENT WILL
SUPPORT AT LEAST ADVISORY WIND-SPEEDS...POSSIBLY STRONGER IN THE
TREASURE AND MAGIC VALLEYS...AND THUNDERSTORMS ALONG THE FRONT WILL
BE STRONG OR POSSIBLY SEVERE IN ALL IDAHO ZONES.  BEFORE THE FROPA
IDAHO ZONES WILL GET INTO THE 80S TO LOWER 90S MONDAY WHILE OREGON
STAYS ONLY IN THE 70S TO MID 80S.  TUESDAY WILL BE A FULL 30 DEGREES
...LOCALLY 35 DEGREES...COLDER WITH HIGHS ONLY IN THE MID 40S TO MID
50S IN THE MOUNTAINS AND MID TO UPPER 50S IN THE VALLEYS.  CURRENT
FORECAST LOOKS GOOD IN ALL RESPECTS AT THIS TIME.  WE ARE PLANNING
TO ISSUE EITHER A WIND ADVISORY OR A HIGH-WIND WATCH LATER TODAY FOR
MONDAY EVENING FOR THE SNAKE BASIN ZONES.

&&

.AVIATION...WIDESPREAD VFR. AREAS OF MVFR CEILINGS AND MOUNTAIN
OBSCURATION ARE POSSIBLE THIS AFTERNOON UNDER SHOWERS AND
THUNDERSTORMS...MAINLY NORTH OF A KBNO-KMYL LINE FROM 22Z - 04Z.
WESTERLY WINDS AT THE SURFACE AT 10 -15 KTS. SOUTHWEST WINDS ALOFT
UP TO 30 KTS AT 10K FEET MSL.

&&

.PREV DISCUSSION...
SHORT TERM...TODAY THROUGH MONDAY...A STRONG COLD FRONTAL PASSAGE IS
EXPECTED MONDAY AFTERNOON. TODAY BROAD SW FLOW WITH DEEPER MOISTURE
OVER CENTRAL OREGON TO CENTRAL IDAHO NORTHWARD WILL ALLOW FOR A
WARMER DAY THAN SATURDAY FROM JORDAN VALLEY THROUGH THE UPPER
TREASURE AND MAGIC VALLEYS TO THE NV BORDER. THE CLOUD AND MOISTURE
BOUNDARY FROM BURNS TO IDAHO CITY MAY ACT AS A FOCUS FOR AFTERNOON
CONVECTION BUT ENOUGH BREAKS ARE EXPECTED NORTH FOR ISOLATED
THUNDERSTORMS NORTH THROUGH BAKER COUNTY AND THE WEST CENTRAL
MOUNTAINS AS WELL. A DEVELOPING SURFACE LOW ABOUT 900 MILES WSW OF
BOISE OFF THE CALIFORNIA COAST WILL LIFT NE TO OVER OREGON MONDAY
MORNING FOR A MILD NIGHT ACROSS THE REGION DUE TO CONSIDERABLE
CLOUDINESS AND INCREASING SHOWERS. AS A NEGATIVELY TILTED UPPER
TROUGH PUSHES INLAND MONDAY THE LOW WILL CONTINUE NE THROUGH CENTRAL
IDAHO IN THE LATE AFTERNOON. OVER IDAHO ORGANIZED CONVECTION IS
EXPECTED TO BREAK OUT EARLY MONDAY. CELLS LOOK TO TRANSITION FROM
ORGANIZED THUNDERSTORMS AS STRONG WIND PRODUCERS TO HEAVY RAINERS AS
ABUNDANT MOISTURE WITH 200 PERCENT OF NORMAL PWAT FOLLOWS THE FRONT
INLAND OVER SE OREGON. TRAINING OF CELLS IS POSSIBLE. IT WILL BE
LOCALLY VERY WINDY OVER SE OREGON ESPECIALLY LATE MONDAY AFTERNOON
AND EVENING. THUNDERSTORM COVERAGE MAY BECOME SCATTERED THIS
AFTERNOON AND EVENING OVER BURNS/VALE AND THE TREASURE VALLEY AREAS
BUT FOR NOW LOOKING AT WIDELY SCATTERED. BETTER FORCING MONDAY
AFTERNOON MAY REQUIRE HIGHER COVERAGE WITH AND SOUTH OF THE LOW
TRACK. GUSTY WINDS WILL SPREAD THROUGH THE AREA MONDAY AFTERNOON.

LONG TERM...MONDAY NIGHT THROUGH SUNDAY...STRONG FRONTAL PASSAGE ON
TRACK TO OCCUR MONDAY NIGHT FOR WIDESPREAD THUNDERSTORMS AND SHOWERS
AHEAD OF THE FRONT...THEN A STEADY RAIN WITH SIGNIFICANTLY COOLER
TEMPERATURES BEHIND IT. ANOTHER ROUND OF SHOWERY PRECIP IS EXPECTED
TUESDAY...AS THE UPPER TROUGH MOVES OVER THE AREA. MODELS HAVE COME
INTO BETTER AGREEMENT FOR WEDNESDAY...AND ALLOW THE UPPER LOW TO
QUICKLY EXIT THE REGION...HOWEVER THE AREA WILL REMAIN UNDER THE
INFLUENCE OF THE BROAD UPPER TROUGH SO DO NOT EXPECT TEMPERATURES TO
REBOUND BACK TO NEAR NORMAL UNTIL THURSDAY WHEN ZONAL FLOW RETURNS.
WEAK RIDGING WILL PROVIDE FURTHER WARMING ON FRIDAY...BEFORE ANOTHER
CLOSED LOW PRESSURE SYSTEM LOOKS TO PUSH INTO THE REGION NEXT
WEEKEND.
