312 AM MDT MON APR 27 2015

.SHORT TERM...TODAY THROUGH WEDNESDAY NIGHT.
LARGE UPPER LEVEL RIDGE WILL MOVE OVERHEAD TUESDAY AND EXPECT DRY
AND WARMING CONDITIONS TODAY AND TUESDAY. TEMPERATURES TODAY WILL
WARM ABOUT 5 TO 10 DEGREES FROM SUNDAY AND WARM ANOTHER 5 TO 10
DEGREES ON TUESDAY AND BE WELL ABOVE SEASONAL NORMAL. A WEAK UPPER
LEVEL SYSTEM WILL APPROACH WEDNESDAY AND WEDNESDAY NIGHT AND
EXPECT SOME ISOLATED SHOWERS AND THUNDERSTORMS MAINLY IN THE
MOUNTAINS LATE WEDNESDAY AND WEDNESDAY NIGHT. THE VERY WARM
CONDITIONS WILL CONTINUE ON WEDNESDAY. MAINLY LIGHT WINDS ARE
EXPECTED THROUGH TUESDAY WITH PERHAPS SOME 10 TO 20 MPH WINDS IN
THE SNAKE RIVER PLAIN ON WEDNESDAY.
GK

.LONG TERM...THURSDAY THROUGH MONDAY. EXTENDED PERIOD CHARACTERIZED
BY ZONAL OR FLAT TROUGH PATTERN. TIMING SHORTWAVE FEATURES
SUFFICIENT TO TRIGGER CONVECTION WILL BE DIFFICULT AT BEST THIS
EARLY IN FORECAST CYCLE. GFS AND ECMWF REMAIN IN GENERAL AGREEMENT
ON THE PATTERN THUS KEPT POP MENTION ACROSS HIGHER ELEVATION AREAS
EACH DAY WITH A NUDGE SLIGHTLY HIGHER WHERE BOTH MODELS AGREE ON
PRECIP PLACEMENT. COULD BE OCCASIONALLY BREEZY DURING AFTERNOONS
WITH ZONAL IMPACT. DMH

&&

.AVIATION...UPPER RIDGE BEGINNING TO SHIFT OVER THE REGION TODAY.
LINGERING MOISTURE MAY BE ENOUGH TO FORM A FEW POCKETS OF LIGHT FOG
THIS MORNING BUT ANY DEVELOPMENT SHOULD BE ISOLATED AND SHORTLIVED.

.SHORT TERM...TODAY THROUGH TUESDAY AFTERNOON. IT SEEMS THE BEST
WAY TO DESCRIBE TODAY`S WEATHER IS MESSY. THE SYSTEM CONTINUES TO
SPLIT AS IT IS MOVING EAST. DRIER AIR IS ALREADY WORKING INTO THE
WESTERN FRINGE OF OUR FORECAST AREA. MEANWHILE...A PRETTY
PERSISTENT BAND OF RAIN AND SNOW EXTENDS FROM AROUND CHALLIS TO
POCATELLO TO NEAR MALAD. AT THE SAME TIME...RAIN AND SNOW IS
INCREASING TO THE EAST OF THE BAND. SNOW IS FALLING DOWN TO
6000-6500FT. WE WILL LIKELY SEE SOME OF THE HIGHER PASSES...LIKE
WE`VE ALREADY SEEN AT WILLOW CREEK SUMMIT...GETTING SNOW AT TIMES.
HOWEVER...THE IMPACTS FOR MOST OF THEM WILL BE MINIMAL EXCEPT FOR
WILLOW CREEK AND HEADING OVER TETON PASS. THOSE TWO PASSES WILL
EVENTUALLY SEE IMPROVING CONDITIONS LATER THIS MORNING. AS THE DAY
WEARS ON...WE WILL SEE A GRADUAL SHIFT TO THE EASTERN HIGHLANDS WITH
THE FOCUS FOR PRECIPITATION. SNOW LEVELS WILL BOUNCE BACK TO
6500-7500FT BY AFTERNOON. IT DOES APPEAR THAT WE WILL SEE SOME
INSTABILITY SHOWERS ACROSS PORTIONS OF THE CENTRAL MOUNTAINS AND
SNAKE PLAIN. THE GFS AND THE HRRR ARE ACTUALLY TRYING TO DEPICT
THE POTENTIAL FOR A CONVERGENCE BAND...POSSIBLY AS FAR SOUTH AS
CRATERS TO AROUND FORT HALL. THAT IS SOMETHING THAT WILL NEED TO
BE MONITORED CLOSELY. BREEZY CONDITIONS WILL DEVELOP IN TWO
SEPARATE LOCATIONS TODAY. THE FIRST WILL BE ACROSS THE UPPER PLAIN
AND HIGHLANDS AS NORTHERLY WINDS KICK IN. THE MAGIC VALLEY AND
SOUTH-CENTRAL HIGHLANDS IS THE OTHER...AND WILL LIKELY SEE THE
STRONGEST WINDS. SUSTAINED WINDS OF 20-30 MPH ARE FORECAST WITH
30-35 MPH IN ISOLATED SPOTS. THIS IS TOO LOW FOR A WIND
ADVISORY...BUT IF ENOUGH PLOWING IS ONGOING THERE COULD BE SOME
BLOWING DUST IN AREAS THAT SAW LITTLE TO NO RAINFALL.

MONDAY AND TUESDAY WILL BE DRIER AND MUCH WARMER WITH HIGH
PRESSURE BUILDING ACROSS THE WEST. BY TUESDAY...HIGHS WILL BE WELL
INTO THE 70S FOR THE VALLEYS AND 50S/60S IN THE MOUNTAINS. KEYES

.LONG TERM...TUESDAY NIGHT THROUGH SUNDAY NIGHT. BOTH GFS AND ECMWF
IN AGREEMENT WITH THE UPPER RIDGE MOVING OFF TO THE EAST AND A
STRONG UPPER TROF MOVING INTO THE PAC NW BY WED MORN. THE TROF THEN
PASSES THRU ID ON THU. MOISTURE APPEARS TO BE LIMITED WITH THIS
SYSTEM. THIS WILL RESULT IN A FEW SHOWERS IN THE CENTRAL MTNS WED
AFTN AS THE INCREASING SW FLOW INTERACTS WITH THE TERRAIN. PRECIP
INCREASES IN COVERAGE ACROSS THE CENTRAL MTNS AND INTO THE UPPER
SNAKE HIGHLANDS WED NIGHT AS THE UPPER TROF APPROACHES. BY THU...A
COLD FRONT PASSES THRU PUSHING MOST OF THE PRECIP OUT OF THE AREA
EXCEPT FOR LINGERING SHOWERS IN THE EASTERN HIGHLANDS. STRONG WEST
TO SW WINDS ALONG WITH COOLER TEMPS ON THU. THE ECMWF IS A LITTLE
SLOWER WITH THIS SYSTEM...SO PRECIP IS A LITTLE MORE WIDESPREAD THAN
THE MOSTLY DRY GFS. NOW THE PICTURE GETS MUDDY. THE GFS DEVELOPS A
BROAD RIDGE OVER THE PAC NW ON FRI...WHILE THE ECMWF DOES JUST THE
OPPOSITE WITH A BROAD TROF. THE GFS MAINTAINS A DRY FCST THRU SUN
WITH A DOMINANT RIDGE...WHILE THE ECMWF DEVELOPS A CLOSED LOW OVER
WA. THE ECMWF SUGGESTS A WET SUN AND SUNDAY NIGHT...WHILE THE GFS IS
DRY. WILL CARRY LOW CHC FOR SHOWERS OVER THE EASTERN HIGHLANDS SUN
AND SUN NIGHT AND LEAVE THE REST OF THE FCST AREA DRY UNTIL THE
PICTURE BECOMES CLEARER. HEDGES

203 PM MDT SAT APR 25 2015

.SHORT TERM...TONIGHT THROUGH TUESDAY.

A DEEP LOW PRESSURE SYSTEM CONTINUES TO MOVE THROUGH THE AREA THIS
AFTERNOON. SHOWERS HAVE BEGUN TO DEVELOP EARLY THIS AFTERNOON.
MODELS SHOW SHOWERS BECOMING MORE WIDESPREAD THROUGHOUT THE
AFTERNOON AND PERSISTING THROUGH THE EVENING. A FEW RUMBLES OF
THUNDER REMAIN POSSIBLE INTO THE EVENING AS MODELS SUGGEST SOME WEAK
INSTABILITY OVER THE REGION. SNOW LEVELS WILL FALL TO BETWEEN
5000 AND 5500 FEET OVERNIGHT. EXPECT SOME SNOW ACCUMULATIONS ABOVE
THESE LEVELS WITH 2 TO 5 INCHES POSSIBLE ACROSS THE CENTRAL
MOUNTAINS AND 1 TO 3 POSSIBLE ACROSS THE EASTERN HIGHLANDS. NOT
EXPECTING SIGNIFICANT IMPACT ISSUES WITH THESE SNOW AMOUNTS
THEREFORE WILL HOLD OFF ON ADVISORIES AT THIS TIME. THE SYSTEM
WILL BEGIN TO MOVE AWAY FROM THE REGION ON SUNDAY. SHOWERS WILL
GRADUALLY COME TO AN END ACROSS THE REGION...BUT WILL PROBABLY
HANG ON THE LONGEST ACROSS THE EASTERN HIGHLANDS BECAUSE OF
PROXIMITY TO THE LOW. HIGH PRESSURE WILL BUILD BACK INTO THE AREA
FOR MONDAY AND TUESDAY...WITH A RETURN OF PLEASANT CONDITIONS TO
THE REGION.

VALLE

.LONG TERM...TUE NIGHT THROUGH NEXT SAT NIGHT. IN THE LONGWAVE
PATTERN THERE IS A GRADUAL DE-AMPLIFYING OF THE WEST COAST
TROUGH...BUT IT IS SO SUBTLE THAT UPPER LEVEL SOUTHWESTERLY FLOW
CONTINUES FOR THE NORTHERN ROCKIES AND NORTHERN GREAT BASIN. THE
WEAKENING PATTERN MAKES THE EXTENDED FORECAST MORE SHORT-WAVE DRIVEN
AND THUS LESS AGREEMENT AMONG GUIDANCE PRODUCT SUITES AND LESS RUN
TO RUN CONSISTENCY. TUE NIGHT AND WED SHOULD BE DRY AS THE INTENSE
RIDGE OF THE NEAR TERM FORECAST CONTINUES...BUT AFTER THIS THE ECMWF
AND GFS DIFFER ON INTENSITY AND TIMING OF THE NEXT SHORTWAVE. BOTH
THE GFS AND ECMWF HAVE GOTTEN WETTER FOR WED NIGHT/THU MORNING...SO
HAVE TRENDED HIGHER FOR THAT PERIOD...BUT OTHERWISE IT IS A FAIRLY
DRY FORECAST IN SPITE OF THE WEST COAST TROUGHING.  LITTLE CHANGE TO
THE FORECAST FROM THIS MORNING. MESSICK

&&

.AVIATION...LOOKS LIKE SHOWERS AND THUNDERSTORMS WILL BE SPARSER
THIS AFTERNOON THAN PREVIOUSLY THOUGHT...WITH MARGINAL VFR HOLDING
OFF UNTIL THE OVERNIGHT HOURS. STILL A RISK OF -TSRA BUT NOT MUCH
MOISTURE TO WORK WITH. ALSO...THE INSTABILITY IS FIGHTING AGAINST
SYNOPTIC SUBSIDENCE. BY SUN MORNING...THE PROBLEMS SHOULD CONTINUE
ONLY AT KIDA AND KPIH WITH KSUN SCATTERED OUT AND KBYI ONLY HAVING
THE SLIGHTEST RISK OF MARGINAL VFR. THE ONE SURPRISE IT HE AMOUNT OF
WIND DURING THE OVERNIGHT HOURS. GUSTY WIND HAS ALREADY DEVELOPED IN

MOISTURE TO WORK WITH. ALSO...THE INSTABILITY IS FIGHTING AGAINST
SYNOPTIC SUBSIDENCE. BY SUN MORNING...THE PROBLEMS SHOULD CONTINUE
ONLY AT KIDA AND KPIH WITH KSUN SCATTERED OUT AND KBYI ONLY HAVING
THE SLIGHTEST RISK OF MARGINAL VFR. THE ONE SURPRISE IT HE AMOUNT OF
WIND DURING THE OVERNIGHT HOURS. GUSTY WIND HAS ALREADY DEVELOPED IN
WESTERN ID AND EXPECT IT TO DEVELOP THIS AFTERNOON AND EVENING AT
ALL AIRPORTS...MAINLY FROM THE WEST AND NORTHWEST. MESSICK

.SHORT TERM...TODAY THROUGH MONDAY AFTERNOON. WE STILL HAVE THE
MAIN LOW CENTERED AROUND SEATTLE AND VANCOUVER THIS MORNING.
ONE WAVE SPINNING AROUND THAT CONTINUES TO SHIFT NORTHEAST THIS
MORNING. BY SUNRISE...LINGERING RAIN AND SNOW WILL BE CONFINED TO
ALONG THE WYOMING BORDER. ANOTHER BATCH WILL EVENTUALLY SHIFT
AWAY FROM THE MACKAY TO ISLAND PARK AREA. SNOW LEVELS ARE DOWN TO
5500-6500FT..SO WE ARE SEEING SNOW DOWN LOW IN THOSE AREAS EARLY
ON. SOME LIGHT ACCUMULATION IS EXPECTED ON GRASSY SURFACES AND IT
APPEARS THAT A FEW SPOTS ARE SEEING SLUSHY/SLICK SPOTS ON THE
ROADS. THEY SHOULD TURN BACK TO WET AFTER THE SUN COMES UP AND
TRAFFIC INCREASES. THE MAIN SYSTEM WILL MOVE EASTWARD SLOWLY AND
SPLITS...WITH A CLOSED LOW FORMING NEAR THE FOUR CORNERS AND THE
NORTHERN BRANCH WEAKENING. MORE CLOUDS ALONG WITH SHOWERS AND
ISOLATED STORMS OVERTAKE EASTERN IDAHO BY AFTERNOON. DON`T BE
SURPRISED IF SOME GUSTY WINDS AND/OR SMALL HAIL OCCUR WITH
STRONGER CELLS...AS WELL AS LOCALLY HEAVIER RAIN OR SNOW. THE
MODELS RAPIDLY DISAGREE FOR TONIGHT/SUNDAY MORNING ON WHERE TO
PLACE THE MAIN BAND OF PRECIPITATION...WHICH ALSO WILL PLAY HAVOC
ON HOW MUCH AIR WORKS IN FROM THE WEST. AS THIS DRY SLOT WORKS UP
THE PLAIN...EXPECT INCREASING WINDS. IRONICALLY...THE MODELS ARE
QUICKLY BACK IN PHASE BY SUNDAY AFTERNOON. THE MAIN AREA OF
PRECIPITATION SHIFTS TO ALONG THE WYOMING BORDER...WITH SOME
LINGERING SHOWERS ACROSS THE CENTRAL MOUNTAINS AND UPPER SNAKE
PLAIN. WE WILL NEED TO MONITOR AS WE MAY SEE A CONVERGENCE BAND
DEVELOP. SNOW LEVELS REBOUND TO 6500-7500FT TOMORROW...BRIEFLY
DROPPING ABOUT 1000FT IN THE MORNING. WE ARE FORECASTING AN
ADDITIONAL 0.10-0.40 INCHES OF WATER. THAT EQUATES TO 1-4 INCHES
IN THE HIGH COUNTRY WITH LIGHT AMOUNTS AT LOWER ELEVATIONS IF AND
WHERE IT MANAGES TO SNOW.

HIGH PRESSURE QUICKLY BEGINS BUILDING ACROSS THE WEST. THAT
RETURNS US TO DRY AND ABOVE NORMAL TEMPERATURES FOR THE FIRST PART
OF THE WORKWEEK. KEYES

.LONG TERM...MONDAY NIGHT THROUGH SATURDAY NIGHT. BOTH GFS AND ECMWF
ARE IN AGREEMENT WITH WARM AND DRY CONDITIONS INTO WED DUE TO A
MAJOR UPPER RIDGE OVER THE WEST. THE RIDGE AXIS MOVES TO THE EAST ON
WED...THE GFS BEING A LITTLE SLOWER. BY WED NIGHT...THE MODELS PART
COMPANY. THE ECMWF DEVELOPS A STRONG ZONAL PATTERN OVER THE PAC
NW...WHILE THE GFS SUGGESTS STRONG SW FLOW AHEAD OF A CLOSED UPPER
LOW OVER THE PAC NW COAST. BOTH MODELS CALL FOR ISOLD SHOWERS/TSTMS
OVER THE CENTRAL MTNS AND EASTERN HIGHLANDS THU THRU SAT. EVENTUALLY
THE MODELS COME TOGETHER SOMEWHAT BY FRI WITH BOTH SHOWING A
POSITIVE TILT UPPER TROF OVER THE WEST. ALTHO NOT CONDUCIVE TO
