AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BOISE ID
841 PM MDT MON APR 15 2013

.DISCUSSION...SHOWER ACTIVITY IS DIMINISHING THIS EVENING OVER SE
OREGON AND SW IDAHO AS ATMOSPHERE STABILIZES. A BROAD UPPER LOW
OVER THE AREA WILL PROVIDE THE NECESSARY LIFT TO CONTINUE LIGHT SNOW
SHOWERS OVER THE WEST CENTRAL AND BOISE MTNS OVERNIGHT...OTHERWISE
THE REST OF SE OREGON AND SW IDAHO IS DRY AFTER MIDNIGHT. A SECOND
CIRCULATION DEVELOPS OVER CENTRAL UT EARLY TUESDAY MORNING THAT
COULD DRAW SHOWER ACTIVITY INTO THE SNAKE RIVER VALLEY AND SE
OREGON TOWARD SUNRISE. HAVE MADE MINOR UPDATES TO THE POPS FOLLOW
THE NOTED TRENDS.

&&

.AVIATION...SCATTERED LOCALLY MVFR SNOW SHOWERS...MAINLY OVER THE
HIGHER TERRAIN...WILL CONTINUE THIS EVENING...BECOMING ISOLATED BY
06Z. ON TUESDAY SNOW SHOWERS WILL INCREASE IN COVERAGE MAINLY OVER
THE HIGHER TERRAIN OF IDAHO...WITH A SLIGHT CHANCE OF THUNDERSTORMS
AFTER 21Z.  SURFACE WINDS...NORTHWEST 10-15 KTS INCREASING TO 15-25
KTS AFTER 18Z. WINDS ALOFT...NORTHWEST TO NORTH UP TO 15 KTS AT 10K
FEET MSL.

&&

.PREV DISCUSSION...
SHORT TERM...ONLY SLIGHT DIFFERENCES FROM PREVIOUS FORECASTS.
BURNS/OR HAS HAD LIGHT SNOW SHOWERS TODAY AND I/R SATELLITE LOOP
AND RADAR MOSAIC SHOW CYCLONIC CIRCULATION CLOSE BY SO THE UPPER
LOW MUST BE NEAR THERE.  THAT POSITION WOULD BE WEST OF PROG
POSITION AND THE LOW MAY STAY IN OUR CWA A LITTLE LONGER THAN
PROGGED.  POPS HAVE BEEN INCREASED SLIGHTLY FOR TONIGHT IN THE
OREGON ZONES AND IN THE MOUNTAINS SOUTH OF THE SNAKE BASIN IN
IDAHO.  INSTABILITY WILL CONTINUE TO PROVIDE A SLIGHT CHANCE OF
THUNDERSTORMS THIS EVENING...BUT ONLY IN SERN ZONES IN IDAHO
TUESDAY AFTERNOON.  THE SNAKE BASIN WILL REMAIN THE LEAST
FAVORABLE AREA FOR STORMS.  TEMPS WILL CONTINUE COOL THROUGH
WEDNESDAY.  WEDNESDAY WILL BE QUITE WINDY BUT NO ADVISORIES WILL
BE ISSUED AT THIS TIME.  THE STRONGER WINDS WILL BE DUE TO A
TIGHTENING SURFACE PRESSURE GRADIENT AS THE CURRENT LOW PRESSURE
SYSTEM MOVES AWAY.  WINDIEST PLACES WEDNESDAY SHOULD BE IN OREGON
AND THE TREASURE VALLEY IN IDAHO...WITH SOUTH-CENTRAL IDAHO
/INCLUDING THE MAGIC VALLEY/ NOT QUITE AS WINDY.

LONG TERM...WEDNESDAY NIGHT THROUGH MONDAY...A BRIEF DRY PERIOD ON
THURSDAY UNDER COOL NORTHERLY FLOW ALOFT WILL KEEP TEMPERATURES AT
8-10 DEGREES BELOW NORMAL. EXPECT WIDESPREAD PRECIPITATION
ASSOCIATED WITH THE PASSAGE OF A SHORT WAVE TROUGH FRIDAY INTO EARLY
SATURDAY...WITH SNOW LEVELS RANGING FROM 6000-7000 FEET MSL. MOIST
NORTHWEST FLOW CONTINUES INTO THE WEEKEND AND EARLY NEXT WEEK AS THE
UPPER LEVEL RIDGE OFF THE SOUTHERN CALIFORNIA COAST IS SUPPRESSED BY
LOW PRESSURE SYSTEMS MOVING ACROSS WESTERN CANADA. THIS IS A
SIGNIFICANT CHANGE FOR WHAT THE MODELS HAVE BEEN PREVIOUSLY SHOWING
THE LAST TWO DAYS OF A HIGH AMPLITUDE RIDGE OVER THE WESTERN U.S.
FOR THIS WEEKEND. MOST MODEL SOLUTIONS NOW FAVOR A CONTINUATION OF
THE CURRENT PROGRESSIVE PATTERN WITH PERSISTENT NORTHWEST FLOW AND
WEAK TROUGHS BRING CHANCES OF PRECIPITATION TO THE AREA.  TEMPS LOOK
TO REMAIN NEAR OR BELOW NORMAL THIS WEEKEND INTO EARLY NEXT WEEK.
