AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE POCATELLO ID
321 AM MDT MON APR 8 2013

.SHORT TERM...TODAY THROUGH WEDNESDAY. WE ARE WATCHING THE MAIN
STORM SYSTEM SPLITTING AS IT MOVES INTO THE GREAT BASIN AND
NORTHERN ROCKIES THIS MORNING. THIS HELPING TO PRODUCE SOME EARLY
RAIN AND SNOW SHOWERS GENERALLY ALONG AND SOUTH OF THE SNAKE RIVER
ITSELF. ANOTHER AREA OF SHOWERS IS MOVING MOVING VERY SLOW FROM
AROUND RICHFIELD TO WEST OF MONIDA PASS. AS THE LOW CONTINUES TO
DIG INTO NEVADA AND UTAH...THIS WILL PUT THE FOCUS KEEP THE FOCUS
ACROSS THE SOUTHERN AND EASTERN HIGHLANDS AS WELL ALONG THE
INTERSTATE CORRIDOR FROM BURLEY TO IDAHO FALLS. SNOW LEVELS THIS
MORNING ARE ROUGHLY 5500-6500FT AS OF 3AM. THEY WILL SLOWLY LOWER
TO THE VALLEY FLOORS ESPECIALLY AS THE COLDER AIR FILTERS IN FROM
THE NORTH TODAY. LIGHT TO LOCALLY MODERATE RAIN AND SNOW IS LIKELY
HERE...WITH PLACES ABOVE 6500FT SEEING 1-4 INCHES OF WET SNOW WITH
A MIX DOWN TO THE VALLEY FLOORS. THE REST OF EASTERN IDAHO WILL
SEE SOME SHOWERS BUT LESS WIDESPREAD...WITH A LITTLE BETTER CHANCE ACROSS
THE CENTRAL MOUNTAINS. WE WILL ALSO WATCH FOR A BAND OF SHOWERS IN
ASSOCIATION WITH A CONVERGENCE EVENT ACROSS THE MAGIC VALLEY. AT
THIS POINT...PRECIPITATION AMOUNTS SHOULD BE LIGHT THERE BUT WE
WILL BE WATCHING THAT THROUGHOUT THE DAY. THE BIGGER STORY THOUGH
APPEARS TO BE VERY STRONG WINDS ACROSS MUCH OF THE AREA. A RATHER
STRONG PRESSURE GRADIENT AND DECENT MIXING WILL DEVELOP THROUGH
THE DAY AND ACTUALLY LAST INTO TUESDAY MORNING. IN TERMS OF
WINDS...WE ARE TARGETING TWO SEPARATE AREAS FOR THIS AFTERNOON AND
EVENING. THE FIRST IS ACROSS THE SOUTH- CENTRAL HIGHLANDS WHERE
THE FLOW FAVORS STRONG NORTH TO NORTHWEST WINDS. THERE WILL BE
SHOWER ACTIVITY AROUND WHICH WILL LIKELY AID IN PRODUCING HIGHER
WIND GUSTS BUT THE OVERALL WIND PATTERN SUPPORTS A HIGHER END WIND
ADVISORY. WE WILL ALSO HAVE TO WATCH THE HIGHER PEAKS LIKE
POMERELLE AND SUCH FOR BLOWING AND DRIFTING SNOW. WE WILL
HIGHLIGHT THIS IMPACT IN THE WIND ADVISORY AND OPT OUT OF A WINTER
WEATHER ADVISORY HIGH UP. THE SECOND AREA IS WHERE STRONG NORTH TO
NORTHEAST WINDS WILL DEVELOP...AND ENCOMPASSES PRETTY MUCH ALL OF
THE UPPER SNAKE HIGHLANDS AND MOST OF THE SNAKE PLAIN...INCLUDING
THE FAR EASTERN FRINGE OF THE EASTERN MAGIC VALLEY. WE USUALLY
DON'T SEE WIND EVENTS COMING WITH THIS WIND PATTERN...BUT ALL OF
THE DATA INDICATES WE WILL A WIND EVENT HERE. A SECOND WIND
ADVISORY WILL BE ISSUED THROUGH THIS EVENING FOR THESE LOCATIONS.
THE REST OF THE AREA WILL SEE 20-30 MPH WINDS WITH HIGHER GUSTS
INCLUDING SUN VALLEY AND HAILEY.

FOR TONIGHT AND TUESDAY...THE FOCUS OF PRECIPITATION WILL SHIFT TO
MAINLY THE SOUTHEAST CORNER AND EVENTUALLY OUT OF THE STATE BY
LATE AFTERNOON AS THE LOW MOVES TOWARD THE PLAINS. WINDS WILL
CONTINUE BE STRONG...BUT WE SHOULD SEE SOME DECOUPLING AT THE
SURFACE OVERNIGHT. HOWEVER...EXPECT JUST OFF THE VALLEY FLOORS AND
IN THE MOUNTAINS THEY WILL CONTINUE TO BLOW. WINDS WILL CONTINUE
TO BE STRONGEST ACROSS THE SAME AREAS WHERE THE WIND ADVISORIES
FOR EARLIER IN THE DAY ARE POSTED. THE DAY OR EVENING SHIFT MAY
NEED TO EXTEND THE HEADLINES IF THE WINDS DON'T DIE OFF AS
FORECAST. THE WINDS FINALLY DIE OFF RELATIVELY QUICKLY TUESDAY
AFTERNOON. FOR THE REST OF THE SHORT TERM...WE WILL SEE SOME
HIGHER CLOUDS AS A BRIEF RIDGE BUILDS ACROSS IDAHO. BY LATE
WEDNESDAY...THE NEXT SYSTEM APPROACHES AND WILL HELP KICK OFF A
FEW SHOWERS ACROSS PORTIONS OF THE CENTRAL MOUNTAINS. TEMPERATURES
WILL BE TRICKY TODAY AS EVERYTHING DEPENDS ON CLOUDS/SHOWERS AND
COLDER AIR FILTERING IN. WE ARE LOOKING AT 30S AND 40S FOR MOST
LOCATIONS...IT CLOSER TO 50 ACROSS THE MAGIC VALLEY. BY
WEDNESDAY...HIGHS WILL BE QUICKLY BACK INTO 50S AND POSSIBLY LOW
60S IN THE VALLEYS. OVERNIGHT LOWS TONIGHT AND TUESDAY NIGHT WILL
BE QUITE COLD WITH 10S AND 20S AREAWIDE TOMORROW NIGHT.  KEYES

.LONG TERM...WEDNESDAY NIGHT THROUGH SUNDAY. MODELS ARE IN GOOD
AGREEMENT WEDNESDAY NIGHT THROUGH FRIDAY. THE MOST SIGNIFICANT
CHANGE IS THE TIMING OF THE DISTURBANCE IN WESTERLY FLOW OFF THE
PACIFIC WEDNESDAY NIGHT AND EARLY THURSDAY MORNING. THIS IS EARLIER
THAN PREVIOUS MODEL RUNS THAT FAVORED THE DISTURBANCE CROSSING
SOUTHEAST IDAHO DAY TIME THURSDAY. SNOW AMOUNTS OF 1 TO 3 INCHES
STILL FAVORED IN THE MOUNTAINS. FOR SATURDAY AND SUNDAY...STORM
TRACK WILL BE SHIFTING SOUTHWARD WITH BROAD TROUGH OVER THE PACIFIC
NORTHWEST. MODEL DIFFERENCES CAN BE QUITE SUBSTANTIAL. THE ECMWF IS
MORE INLAND WITH A LOW PRESSURE CIRCULATION WHILE THE GFS IS MORE
ALONG THE WEST COAST PICKING UP MORE MOISTURE. BOTH BRING A CHANCE
OF PRECIPITATION BOTH DAYS...JUST WETTER WITH THE GFS. HAVE ADJUSTED
AFTERNOON HIGH TEMPERATURES SATURDAY AND SUNDAY A COUPLE OF DEGREES
WARMER...BASICALLY A COMPROMISE BETWEEN MODELS. RS

&&

.AVIATION...RAIN SHOWERS WITH MVFR CEILINGS HAVE DEVELOPED FROM NEAR
KBYI TO KIDA THIS MORNING. MODELS DID NOT PARTICULARLY HIT THE
LOCATION AND TIMING VERY WELL. WITH THE LOW DROPPING RAPIDLY TOWARDS
NEVADA THIS MORNING...ESTIMATE THESE SHOWERS AND LOW CEILINGS TO
PERSIST PERHAPS UNTIL 16Z...THEN DISSIPATE FOR MUCH OF THE DAY. WILL
WATCH FOR WRAP AROUND CIRCULATION TO BRING SHOWERS CLOSE TO KIDA AND
KPIH LATER THIS EVENING. THE OTHER MAJOR CONCERN IS SURFACE WINDS.
SOUTH TO SOUTHWEST WIND IN THE UPPER SNAKE PLAIN EXPECTED TO SHIFT
TO THE NORTH 11-13Z TIME FRAME BASED ON RAPID UPDATE MODEL...THEN
INCREASE IN SPEED 16-18Z TO 15 TO 25 KTS GUST 35 KTS AND DIMINISH IN
STRENGTH BY 09/03Z. BELIEVE MOS GUIDANCE WILL PROVE TOO LIGHT ON WIND
SPEEDS TODAY. WIDESPREAD VFR CONDITIONS EXPECTED TUESDAY. RS
