224 PM MST SAT JAN 31 2015

.SHORT TERM...TONIGHT...LOW LEVEL STRATUS CLOUDS AND PATCHY FOG
WILL BE THE MAIN PROBLEM IN THE SNAKE PLAIN AND LOWER VALLEY
AREAS. BY SUNDAY AFTERNOON WE WILL BEGIN TO SEE A CHANGE IN THE
WEATHER WITH INCREASING MIDDLE AND HIGH LEVEL CLOUDS APPROACHING
FROM THE WEST. MOIST AIR OFF THE PACIFIC WILL BEGIN TO BRING SOME
SNOW TO THE MOUNTAINS THE NEXT FEW DAYS. ACCUMULATIONS ABOVE 5500
FEET OF 2 TO 5 INCHES IS POSSIBLE THROUGH TUESDAY MORNING. FOR THE
LOWER VALLEYS...SNOW LEVELS OF 4500 TO 5000 FEET DURING THE DAY
WILL MEAN SOME MIXED RAIN AND SNOW IN THE LOWER VALLEYS DURING
THE AFTERNOON. SUNDAY NIGHT...ANY ACCUMULATION SHOULD BE LIMITED
TO LESS THAN AN INCH ON THE VALLEY FLOORS...BENCH AREAS ON THE
EAST SIDE OF THE SNAKE PLAIN SUNDAY NIGHT AND MONDAY 1 TO 2 INCHES.
WINDS IN THE SNAKE PLAIN MONDAY NIGHT AND EARLY TUESDAY INCREASE
TO 15 TO 25 MPH...ALONG WITH SNOW LEVELS RISING TO AROUND 6000
FEET ON TUESDAY...AND AFTERNOON HIGHS FROM THE UPPER 30S TO MIDDLE
40S. RS

.LONG TERM...TUE NIGHT THROUGH NEXT SAT NIGHT. 500MB 5-WAVE HAS THE
GEM STATE CAUGHT BETWEEN A GULF OF ALASKA TROUGH AND A GULF OF
CALIFORNIA HIGH...SLIGHTLY CLOSER TO THE HIGH THAN THE TROUGH. BUT
THE STORM TRACK DOES CUT THROUGH NORTHERN IDAHO AND THUS EXPECT AN
UNSETTLED EXTENDED FORECAST. THE PATTERN OVER THE WESTERN STATES AND
EASTERN PACIFIC ACTUALLY AMPLIFIES...KEEPING THE FORECAST AREA IN
GENERAL WARM SOUTHWESTERLY AIR FLOW...ESPECIALLY EARLY IN THIS
PERIOD. THIS EXPLAINS THE WARM TEMPERATURES IN THE SECOND HALF OF
THE FORECAST TIME. GFS AND ECMWF HAVE STRONG MAGNITUDE AND TIMING
DIFFERENCES IN THE SHORTWAVES THAT ARE PUSHED THROUGH. THE GFS IS
DRIER IN THE FIRST HALF...THEN WETTER THAN THE ECMWF IN THE SECOND
HALF OF THIS PERIOD. HAVE ATTEMPTED TO COMPROMISE BETWEEN THE TWO.
THE ONLY DAY THAT SEEMS VERY SURE IS FRI NIGHT WHEN MODERATE TO
HEAVY PRECIPITATION IS BROUGHT IN BY BOTH SOLUTIONS. HAVE GENERALLY
MADE IT CLOUDIER WITH HIGHER POP THAN PREVIOUS FORECAST. WINDS WITH
THE FRI NIGHT STORM COULD BE FIRST SIGNIFICANT IN A WHILE...BUT
SHOULD GENERALLY BE BREEZIER THAN LATELY WITH NO REAL CHANCE FOR
HIGH PRESSURE TO DOMINATE THE GEM STATE. MESSICK

&&

.AVIATION...USED CONDITIONAL CLIMATOLOGY TABLES TO ATTEMPT TO FIGURE
OUT A STRATUS LIFTING TIME...AS MOS GUIDANCE CONTINUES TO BE SUSPECT
AND AT TIMES THE GFS IS THE EXACT OPPOSITE OF THE NAM OUTPUT.
CONDITIONAL CLIMATOLOGY HAS A PRETTY GOOD HISTORY WITH BREAKOUT
OCCURING LATE THIS AFTERNOON/THIS EVENING FOR KIDA AND KPIH. AFTER
01/06Z...NO CLIMATOLOGY-BASED INFORMATION...SO AS FAR AS SUN MORNING
GOES...HAVE LOOKED AT TIME-HEIGHT CROSS SECTIONS. KBYI AND KPIH
AIRDROMES APPEAR TO CLEAR OUT EARLIER THAN THIS MORNING...DURING THE
EARLY TO MID-MORNING HOURS ON SUNDAY. KIDA APPEARS THE MOST STUBBORN
OVERNIGHT...BUT STILL EXPECTED TO ACTUALLY CLEAR SUNDAY
MORNING...WHICH THEY WILL NOT THIS AFTERNOON. WIND CONTINUES
NEGLIGIBLE AT THE SURFACE. A MID-LEVEL DECK WITH SOME WIND ALOFT
WILL HELP TO BREAK UP THE STRATUS SITUATION IN ADVANCE OF A TROUGH
EXPECTED MON AFTERNOON/EVENING. KSUN IS ONLY AT RISK FOR STRATUS IF
A GOOD SOUTHERLY WIND DEVELOPS IN THE AFTERNOON WITH ABUNDANT
STRATUS IN THE LOWER PARTS OF THE WOOD RIVER VALLEY. IT CAME VERY
CLOSE TODAY...BUT DO NOT BELIEVE THE STRATUS WILL EXTEND AS MUCH AS
IT DID THIS MORNING AND THE KSUN AIRDROME SHOULD ONLY HAVE TO
CONTEND WITH MID-LEVEL CIGS AND POSSIBLE SHOWERS IN THE VCNTY.

EASTERN OREGON. OTHERWISE VFR CONDITIONS WILL PREVAIL UNDER MOSTLY
CLEAR SKIES THROUGH SATURDAY NIGHT. SURFACE WINDS...VARIABLE LESS
THAN 10 KTS. WINDS ALOFT...NORTH 10-20 KTS UP THROUGH 10K FT MSL.

OUTLOOK FOR SUNDAY...LATE NIGHT AND MORNING VALLEY FOG AND STRATUS
WILL DISSIPATE BY AROUND 18Z. INCREASING AND LOWERING CLOUDS WILL
LEAD TO PRECIPITATION ACROSS BAKER COUNTY OREGON AND THE WEST
CENTRAL IDAHO MOUNTAINS BY LATE AFTERNOON...WITH SNOW LEVELS NEAR
4500 FT MSL.

.PREV DISCUSSION...
SHORT TERM...TONIGHT THROUGH SUNDAY...STRATUS IS FOUND IN MUCH OF
SRN HARNEY AND MALHEUR COUNTIES AND ALSO OWYHEE COUNTY. THE
WESTERN MAGIC VALLEY HAS ITS SHARE AS WELL. THIS WILL CONTINUE
RECEDING FOR THE REMAINDER OF THE AFTERNOON BEFORE EXPANDING AGAIN
OVERNIGHT. MODELS INDICATE MORE DRYING TOMORROW AFTERNOON THAN
TODAY...SO WE ARE FORECASTING LESS STRATUS SAT AFTERNOON. ALOFT...
WE ARE IN THE COL AT THE NRN EDGE OF A LARGE UPPER LOW CENTERED NEAR
LAS VEGAS. AS THIS LOW MOVES SOUTH AND THEN EAST...NW FLOW WILL
BUILD INTO THE PAC NW. THERE IS AN ABOVE-AVERAGE AMOUNT OF MID AND
HIGH LEVEL MOISTURE IN THIS FLOW...WHICH MEANS WE WILL SEE MID AND
HIGH CLOUDS TOMORROW THROUGH SUNDAY. ENOUGH MOISTURE...AND A WEAK
SYSTEM...MOVE OVER THE RIDGE ON SUNDAY THAT WE HAVE MAINTAINED
POPS IN THE NRN PART OF THE CWA...AND ALSO MUCH OF SE OREGON...FOR
SUNDAY. THE BEST CHANCE WILL BE IN THE AFTERNOON. TEMPS WILL
REMAIN SIMILAR TO RECENT DAYS THROUGH THE PERIOD. WINDS WILL
INCREASE OUT OF THE SOUTHEAST SUNDAY AFTERNOON...GUSTING 15 TO 20
MPH IN THE UPPER TREASURE VALLEY.

LONG TERM...SUNDAY NIGHT THROUGH FRIDAY...FLAT UPPER LEVEL RIDGE
OVER THE REGION AS A SERIES OF WEAK SYSTEMS MOVES EAST OVER
SOUTHERN CANADA. THIS WEATHER PATTERN WILL BRING A MOIST WEST
TO NORTHWEST FLOW OVER THE AREA MONDAY THROUGH WEDNESDAY FOR A
CHANCE OF MOUNTAIN SNOW AND VALLEY RAIN. TEMPERATURES WILL COOL
BUT WILL STILL BE NEAR NORMAL. THURSDAY AND FRIDAY MODELS ARE
TRENDING TOWARD THE RIDGE REDEVELOPING ALONG THE WEST COST AS LOW
PRESSURE DIGS SOUTH OVER THE EASTERN PACIFIC. MODELS IN FAIRLY
GOOD AGREE ON THE WEATHER PATTERN BUT DIFFER ON TIMING AND
PLACEMENT OF PRECIPITATION. FOR NOW WILL TREND POPS TOWARDS

.AVIATION...EXPECT PATCHY MVFR/IFR FOG AND STRATUS BELOW 4500 FT MSL
06Z-18Z IN THE SNAKE RIVER VALLEY...CENTRAL IDAHO MOUNTAINS...AND
EASTERN OREGON. OTHERWISE VFR CONDITIONS WILL PREVAIL UNDER MOSTLY
CLEAR SKIES THROUGH SATURDAY NIGHT. SURFACE WINDS...VARIABLE LESS
THAN 10 KTS. WINDS ALOFT...NORTH 10-20 KTS UP THROUGH 10K FT MSL.

OUTLOOK FOR SUNDAY...LATE NIGHT AND MORNING VALLEY FOG AND STRATUS
WILL DISSIPATE BY AROUND 18Z. INCREASING AND LOWERING CLOUDS WILL
LEAD TO PRECIPITATION ACROSS BAKER COUNTY OREGON AND THE WEST
CENTRAL IDAHO MOUNTAINS BY LATE AFTERNOON...WITH SNOW LEVELS NEAR
4500 FT MSL.

WESTERN MAGIC VALLEY HAS ITS SHARE AS WELL. THIS WILL CONTINUE
RECEDING FOR THE REMAINDER OF THE AFTERNOON BEFORE EXPANDING AGAIN
OVERNIGHT. MODELS INDICATE MORE DRYING TOMORROW AFTERNOON THAN
TODAY...SO WE ARE FORECASTING LESS STRATUS SAT AFTERNOON. ALOFT...
WE ARE IN THE COL AT THE NRN EDGE OF A LARGE UPPER LOW CENTERED NEAR
LAS VEGAS. AS THIS LOW MOVES SOUTH AND THEN EAST...NW FLOW WILL
BUILD INTO THE PAC NW. THERE IS AN ABOVE-AVERAGE AMOUNT OF MID AND
HIGH LEVEL MOISTURE IN THIS FLOW...WHICH MEANS WE WILL SEE MID AND
HIGH CLOUDS TOMORROW THROUGH SUNDAY. ENOUGH MOISTURE...AND A WEAK
SYSTEM...MOVE OVER THE RIDGE ON SUNDAY THAT WE HAVE MAINTAINED
POPS IN THE NRN PART OF THE CWA...AND ALSO MUCH OF SE OREGON...FOR
SUNDAY. THE BEST CHANCE WILL BE IN THE AFTERNOON. TEMPS WILL
REMAIN SIMILAR TO RECENT DAYS THROUGH THE PERIOD. WINDS WILL
INCREASE OUT OF THE SOUTHEAST SUNDAY AFTERNOON...GUSTING 15 TO 20
MPH IN THE UPPER TREASURE VALLEY.

LONG TERM...SUNDAY NIGHT THROUGH FRIDAY...FLAT UPPER LEVEL RIDGE
OVER THE REGION AS A SERIES OF WEAK SYSTEMS MOVES EAST OVER
SOUTHERN CANADA. THIS WEATHER PATTERN WILL BRING A MOIST WEST
TO NORTHWEST FLOW OVER THE AREA MONDAY THROUGH WEDNESDAY FOR A
CHANCE OF MOUNTAIN SNOW AND VALLEY RAIN. TEMPERATURES WILL COOL
BUT WILL STILL BE NEAR NORMAL. THURSDAY AND FRIDAY MODELS ARE
TRENDING TOWARD THE RIDGE REDEVELOPING ALONG THE WEST COST AS LOW

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE POCATELLO ID
159 PM MST FRI JAN 30 2015

.SHORT TERM...TONIGHT THROUGH MONDAY NIGHT.
SOUTHEAST IDAHO REMAINS UNDER THE INFLUENCE OF A HIGH PRESSURE RIDGE
AS ONE DISTURBANCE SLIDES THROUGH MONTANA SATURDAY AND ANOTHER OVER
THE SOUTHWESTERN STATES PULLS FURTHER AWAY FROM US. THAT LEAVES
INVERSIONS AND PATCHY FOG FOR TONIGHT AND SATURDAY NIGHT. A PLUME OF
MOISTURE ASSOCIATED WITH THE LOW IN THE PACIFIC NEAR 160W WILL
ADVANCE ACROSS SOUTHEAST IDAHO SUNDAY NIGHT THROUGH EARLY TUESDAY
MORNING. MODELS HAVE CERTAINLY BEEN JUMPING AROUND WITH THE
MOISTURE. FOR THIS FORECAST...CAME UP WITH 1 TO 5 IN THE
MOUNTAINS...5 BEING ON THE RIDGE TOPS. MONDAY NIGHT LESS THAN 1 INCH
IN THE LOWER VALLEY FLOORS....AND TEMPERATURES SNEAKING ABOVE
FREEZING ON MONDAY. RS

.LONG TERM...TUESDAY THROUGH FRIDAY. WE WILL EVENTUALLY SEE A
TRANSITION BY THE END OF NEXT WEEK TO A STRONGER RIDGE OVER THE
WEST. BEFORE THAT...WE ARE STILL DEALING WITH MOISTURE STREAMING OFF
THE PACIFIC AND INTO IDAHO. WE SHOULD A DECENT CHANCE OF RAIN AND
SNOW ACROSS THE NORTH WHICH IS SUPPORTED BY THE MODELS AND ENSEMBLES
TO AN EXTENT. FARTHER SOUTH...THE MODELS WANT TO KEEP A LOT MOISTURE
AROUND ESPECIALLY IN THE MOUNTAINS TUESDAY AND WEDNESDAY. THAT IS
NOT SUPPORTED NECESSARILY BY MANY OF THE ENSEMBLE FORECASTS. BECAUSE
OF THAT WE ONLY MADE SOME MINOR CHANGES TO THE FORECAST...KEEPING
HIGHER CHANCES UP NORTH WITH A LEAST A SLIGHT CHANCE ACROSS MORE
SOUTHERN LOCALES. AFTER THAT...WE CONTINUED WITH DRIER CONDITIONS.
IT WILL BE INTERESTING TO SEE HOW STRONG THE RIDGE BUILDS. THE
MODELS WANT TO BREAK IT OR SHOVE IT EAST RATHER QUICKLY HEADING INTO
NEXT WEEK. THAT MIGHT BE TOO QUICK. EXPECT WARMING TEMPERATURES WHEN
WE TRANSITION TO THE RIDGE...AS TEMPERATURES OUTSIDE OF INVERSION
AREAS WILL TRY AND PUSH ABOVE 50 IN SOME LOCATIONS. KEYES

&&

.AVIATION...WE CONTINUE WITH VFR CONDITIONS AT ALL FOUR OF OUR TAF
SITES THIS AFTERNOON...WITH HIGH AND MID LEVEL CLOUDS AROUND. WE DO
HAVE SOME POCKETS OF STRATUS AND FOG AROUND THIS AFTERNOON. THE
CLOSEST AREA TO ANY TAF SITE IS NORTH AND WEST OF KBYI. WIND
DIRECTION AND MOISTURE PROFILES SUGGEST AS THE WIND CONTINUE TO TURN
MORE FROM THE WEST...IFR/POTENTIAL LIFR CONDITIONS RUSH BACK UP THE
SNAKE PLAIN. THE FORECAST FOLLOWS THAT TREND WITH STRATUS AND/OR FOG
RETURNING TO KBYI AND KPIH THROUGH THE EVENING HOURS. KIDA IS A
LITTLE MORE IFFY ON THAT BECAUSE THE WINDS STAY NORTHERLY AND KEEP
SLIGHTLY DRIER AIR IN PLACE. WE DID PUT THESE CONDITIONS IN AT KIDA
AFTER MIDNIGHT...BUT CONFIDENCE IS OBVIOUSLY LOWER. IT IS POSSIBLE
THAT IT MAY HAPPEN BECAUSE OF THE NEARBY SNAKE RIVER VS THE OTHER
SCENARIO. KSUN IS EXPECTED TO STAY VFR ALTHOUGH THERE IS A SLIM
CHANCE THAT FOG/STRATUS IS SUCKED INTO THE WOOD RIVER VALLEY IF
WINDS TURN SOUTHEAST. CONDITIONS WILL BEGIN IMPROVING LATER
SATURDAY. KEYES

.SHORT TERM...TODAY THROUGH SATURDAY...A FEW RADAR ECHOES WERE
NEAR THE ID-NV BORDER THIS MORNING ALONG WITH ABUNDANT MID/HIGH
CLOUDS THROUGH THE SOUTH HALF OF IDAHO. PATCHY LOW STRATUS
CONTINUED PER AIRPORT OBS. A TROUGH ON THE NORTH LOW MOVING
THROUGH THE SOUTHWEST MAY BRING ENOUGH MOISTURE FOR ISOLATED
SHOWERS NEAR THE NV-TWIN FALLS COUNTY LINE AS IT SHIFTS EAST
TODAY. BEHIND THAT LOW HIGH PRESSURE AT THE SURFACE AND ALOFT
WILL STRENGTHEN THE INVERSION ACROSS SE OREGON AND SW IDAHO
SATURDAY. TEMPERATURES WILL BE ABOVE NORMAL...WITH MOUNTAIN HIGHS
WELL ABOVE NORMAL.

.LONG TERM...SATURDAY NIGHT THROUGH FRIDAY...MODERATE PACIFIC RIDGE
WILL MOVE INLAND EARLY SUNDAY BUT WILL BE SHORT-LIVED AS AN UPPER
LEVEL TROUGH MOVES EAST OVER BRITISH COLUMBIA...SUPPRESSING RIDGE
HEIGHTS OVER OREGON/IDAHO. AS A RESULT...MOIST WESTERLY FLOW ALOFT
WILL DOMINATE MONDAY THROUGH WEDNESDAY...WARRANTING A CHANCE OF
PRECIPITATION /VALLEY RAIN AND MOUNTAIN SNOW/ THROUGH MID-WEEK.
HEIGHTS WILL REAMPLIFY LATER IN THE WEEK...IN RESPONSE TO AN UPPER
LOW DEEPENING OVER THE NORTH PACIFIC. MAIN EFFECT LOCALLY WILL BE
WARMER TEMPERATURES AND DRY CONDITIONS SOUTH OF THE SNAKE RIVER
THROUGH EARLY FRIDAY. WET CONDITIONS LOOK TO RETURN BY LATE FRIDAY
AS THE UPPER LEVEL RIDGE SHIFTS INLAND AND SOUTHWESTERLY FLOW
TRANSPORTS PACIFIC MOISTURE INLAND.

.AVIATION...LOCAL IFR CONDITIONS IN VALLEY FOG /INCLUDING KBKE AND
KMYL/ THROUGH 16Z THIS MORNING. THE TREASURE VALLEY OF BOTH OREGON
