NATIONAL WEATHER SERVICE BOISE ID
850 PM MDT MON MAR 23 2015

.DISCUSSION...NOW THAT THE CONVECTION IS ENDING FOR TODAY...ALL
EYES TURN WEST TO WATCH THE NEXT SYSTEM SPEED INTO THE AREA.
MOISTURE IS ALREADY POURING INTO THE PAC NW...AND THE COMPLEX SHORT
WAVES THAT MAKE UP THIS SYSTEM WERE LOCATED JUST OFF THE COAST OF
WASHINGTON AND OREGON AS OF 0230Z. THIS WILL BE THE WETTEST ONE
IN THE SERIES OF STORMS WE HAVE BEEN EXPERIENCING SINCE
SATURDAY...AND THE HIGH POPS IN THE FORECAST ARE WARRANTED. WE
WILL SEE PRECIP MOVING BACK INTO SE OREGON BEFORE MIDNIGHT...AND
INTO SW IDAHO WELL BEFORE DAWN. LATEST GUIDANCE STILL SHOWS
MODERATE W WINDS TUE AFTERNOON FROM MOUNTAIN HOME EAST THROUGH
TWIN FALLS AND JEROME...BUT NOT QUITE UP TO ADVISORY LEVELS. NO
CHANGES IN EXPECTATIONS AND NO CHANGES TO THE FORECAST THIS
EVENING.

&&

.AVIATION...MOSTLY VFR EARLY TONIGHT AS SHOWERS AND THUNDERSTORMS
HAVE RAPIDLY SUBSIDED. HOWEVER...MORE SHOWERS AND THUNDERSTORMS
ARE EXPECTED TO MOVE IN FROM WEST TO EAST TONIGHT AND BE NEAR KBNO
24/06Z...KBOI 24/10Z...KTWF 24/13Z. OCCASIONAL MVFR/IFR CONDITIONS

.PREV DISCUSSION...
SHORT TERM...A COUPLE OF FORECAST ADJUSTMENTS SINCE THIS MORNING.
AIR MASS NOT QUITE AS UNSTABLE AS BEFORE IN THE BOISE MOUNTAINS AND
WEST CENTRAL MOUNTAINS THIS EVENING SO HAVE TRIMMED COVERAGE OF
THUNDERSTORMS FROM SCATTERED TO ISOLATED AND LASTING ONLY THROUGH
03Z.  AIR MASS WILL BECOME MORE STABLE AFTER THAT.  KEPT ISOLATED
THUNDERSTORMS THIS EVENING SOUTH OF THE SNAKE BASIN IN IDAHO BUT
REMOVED THEM IN ALL OTHER ZONES.  LATEST MAV AND MET GUIDANCE HAVE
SLIGHTLY LOWERED WIND SPEEDS FOR TUESDAY AFTERNOON IN THE UPPER
TREASURE VALLEY AND WESTERN MAGIC VALLEY SO A WIND ADVISORY IS NO
LONGER A SURE THING.  WILL HOLD OFF ON ADVISORY FOR THIS PACKAGE.
OTHER IDEAS OF PREVIOUS FORECAST STILL HOLD.  THIS AFTERNOON/S SHORT
WAVE TROUGH AND SHOWERS WILL EXIT EAST LATE TODAY.  AFTER A FEW
HOURS CLEARING FROM WEST TO EAST THE NEXT PACIFIC SHORT WAVE TROUGH
WILL COME IN OVERNIGHT THROUGH TUESDAY WITH MORE SHOWERS...AND THAT
TROUGH LOOKS WETTER THAN THE PREVIOUS TWO...SO HIGH POPS ARE IN
EFFECT LATE TONIGHT THROUGH TUESDAY.  DRYING FROM THE NORTHWEST
LATER TUESDAY. CLEARING AND COOLER TUESDAY NIGHT THEN MOSTLY CLOUDY
WEDNESDAY AS A WARM FRONT MOVES THROUGH WITH A CHANCE OF LIGHT RAIN
AND SNOW IN NORTHERN ZONES.

LONG TERM...WEDNESDAY NIGHT THROUGH SATURDAY...LATEST MODEL RUNS
STILL ON TRACK WITH AN UPPER LEVEL RIDGE BUILDING ALONG THE WEST
COAST.  THIS WILL BRING DRY CONDITIONS AND WARMING TEMPERATURES TO
THE FORECAST AREA.  HIGH TEMPERATURES WILL WARM TO 10 TO 15 DEGREES
ABOVE NORMAL IN THE VALLEYS BY SATURDAY WITH MOUNTAIN LOCATIONS
AROUND 5 DEGREES ABOVE NORMAL.

SATURDAY NIGHT THROUGH MONDAY...MAINLY DRY ZONAL FLOW OVER THE
REGION AS THE UPPER LEVEL RIDGE MOVES EAST AND A SHORT WAVE PASSES
NORTH OF US ALONG THE CANADIAN BORDER. TEMPERATURES WILL CONTINUE TO
BE 10-15 DEGREES ABOVE NORMAL...THOUGH THEY/LL BE ON A STEADY
DECLINE THROUGH THE PERIOD AS HEIGHTS LOWER.
