AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BOISE ID
335 AM MDT WED MAR 28 2007

.SHORT TERM...THE LARGE CLOSED LOW THAT AFFECTED THE AREA TUESDAY
AND TUESDAY NIGHT CONTINUES TO DRIFT SLOWLY EASTWARD INTO WYOMING
AND EASTERN UTAH. MODERATE TO HEAVY SNOW SOUTH OF THE SNAKE RIVER TO
THE NEVADA BORDER HAS DIMINISHED CONSIDERABLY AS THE LOW MOVES AWAY.
THEREFORE...WILL CANCEL THE WINTER STORM WARNINGS A COUPLE HOURS
EARLY LEAVING ONLY LINGERING LIGHT SNOW ACCUMULATIONS OR FLURRIES IN
THESE REGIONS FOR A SHORT PERIOD THIS MORNING. MAIN STORY NOW
CONTINUES TO FOCUS ON THE STRONG WINDS THAT REMAIN OVER PARTS OF THE
FORECAST AREA AND THE COLD AIR IN PLACE. TIGHTEST SURFACE GRADIENT
CONTINUES OVER EASTERN OREGON AND EXTREME SOUTHWEST IDAHO AS INTENSE
SURFACE RIDGE BUILDS EASTWARD FROM THE PACIFIC AND THE DEEP CLOSED
LOW DRIFTS EAST OVER UTAH. ALTHOUGH WINDS AGAIN WILL BE STRONG
TODAY...THERE DOES NOT APPEAR TO BE A PERFECT ALIGNMENT BETWEEN THE
SURFACE AND 50H.  WINDS MORE NORTHERLY ABOVE THE SURFACE AND USUALLY
NOT A GOOD DIRECTION TO PRODUCE VERY WINDY CONDITIONS IN THE MAGIC
VALLEY WHERE WIND SPEEDS HAVE BEEN LOWER THAN AREAS TO THE WEST.
HOWEVER...THIS DIRECTION DOES REMAIN FAVORABLE FOR LOCATIONS FROM
BAKER CITY AND ONTARIO OREGON AND SOUTHEAST TO BOISE AND MOUNTAIN
HOME. BELIEVE WE ARE LOOKING AS WINDY CONDITIONS TODAY BUT JUST
BELOW ADVISORY THRESHOLDS. THIS IS A CLOSE CALL AND NEEDS TO BE
MONITORED THROUGH THE DAY. OTHERWISE...CLOUD SHIELD FROM UPPER LOW
EXPECTED TO SLOWLY PULL EAST DURING THE DAY WITH INCREASING AMOUNTS
OF SUNSHINE FROM WEST TO EAST AS IMPROVING CONDITIONS ARRIVE.
TEMPERATURES START THE SLOW PROCESS OF REBOUNDING BACK UP BUT STILL
A COOL DAY IN THE WAKE OF THE TUESDAY STORM SYSTEM. HIGH PRESSURE
AND DRY AIR ALONG WITH WARM AIR ADVECTION SUGGESTS THAT THURSDAY IS
SHAPING UP TO BE A NICE DAY WITH MUCH LIGHTER WINDS...SUNNY SKIES
AND TEMPS RISING TO NEAR OR SLIGHTLY ABOVE NORMAL.

.LONG TERM...THURSDAY NIGHT THROUGH TUESDAY...SUBSIDENCE FOLLOWING
OUR CURRENT UPPER LEVEL TROUGH WILL BRING DRY WEATHER THURSDAY NIGHT
AND FRIDAY. ZONAL FLOW WILL QUICKLY TAKE OVER AS A DEEP UPPER LEVEL
TROUGH BECOMES ESTABLISHED OVER WESTERN CANADA. MODELS AGREE ON THE
OVERALL PATTERN ALTHOUGH THEY DIFFER IN THE DETAILS. TEMPERATURES
AND POPS NEAR CLIMATOLOGY ARE THE BEST FIT FOR THIS SCENARIO. NO
UPDATES WERE NEEDED.

&&

.AVIATION...WIDESPREAD MVFR AND AREAS OF IFR CONDITIONS IN SNOW AND
STRONG GUSTY NORTHWEST SURFACE WINDS WILL CONTINUE EAST AND SOUTH OF
KMUO AND OVER THE CENTRAL MOUNTAINS THIS MORNING. CONDITIONS WILL
IMPROVE TO PREDOMINANT VFR BY THIS EVENING. WINDS ALOFT WILL BE
MODERATE OUT OF THE NORTH.
