AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE POCATELLO ID
1120 AM MST TUE MAR 3 2015

.UPDATE...

UPDATED FORECAST TO CANCEL THE WINTER WEATHER ADVISORY WITH AREA
WEBCAMS AND RADAR SHOWING SNOW ENDING ACROSS THE REGION. SNOW
AMOUNTS WERE GENERALLY IN THE 2 TO 5 INCH RANGE IN THE ADVISORY
AREA WITH MULTIPLE SLICK/ICY ROADS. THERE WERE SOME ISOLATED
HEAVIER AMOUNTS CLOSER TO 7 OR 8 INCHES.

VALLE

&&

.PREV DISCUSSION... /ISSUED 826 AM MST TUE MAR 3 2015/

UPDATE...

EXPANDED THE WINTER WEATHER ADVISORY INTO THE EASTERN MAGIC VALLEY
AND SOUTHERN HIGHLANDS PER RADAR TRENDS. EVEN THOUGH SNOW AMOUNTS
ARE RELATIVELY UNIMPRESSIVE...ANYWHERE BETWEEN 1 AND 5 INCHES
DEPENDING UPON ELEVATION...ROADS ARE EXTREMELY ICY ESPECIALLY IN
THE POCATELLO AREA WHERE MULTIPLE SLIDE OFFS HAVE BEEN REPORTED.
STILL EXPECT SNOW TO COME TO AN END AROUND NOON WITH CLEARING
SKIES THIS AFTERNOON.

VALLE

PREV DISCUSSION... /ISSUED 314 AM MST TUE MAR 3 2015/

SHORT TERM...TODAY THROUGH THU NIGHT. LIGHT SNOW HAS SPREAD
ACROSS THE NORTHERN HALF OF THE FORECAST AREA AND IS PROPAGATING
SOUTHWARD. GUSTY WIND HAS ALSO DEVELOPED BUT IS ALSO KEEPING
AMBIENT TEMPERATURES WARM...SO WIND CHILL NOT REALLY BAD. WHEN THE
FRONT PRESSES THROUGH...WIND WILL SHIFT FROM SOUTHWEST AND WEST TO
NORTH AND NORTHEAST. GUSTS NOT QUITE UP TO WHAT WAS EXPECTED...SO
HAVE REDUCED AREAS OF BLOWING SNOW. ALL PRECIPITATION SHOULD END
BY 03/18Z...SO HAVE SHORTENED THE DURATION OF THE ADVISORY A
LITTLE BIT MORE. COLDER AIR MASS MOVING IN WILL MEAN MUCH COLDER
TEMPERATURES FOR THE AFTERNOON AND TONIGHT. THE UPPER LEVEL RIDGE
TAKES OVER TONIGHT AND DOMINATES THE WEATHER FOR THE DURATION OF
THE PERIOD. MARCH SUNSHINE WILL MEAN A LARGE TEMPERATURE SWING
BACK TO ABOVE 40 DEG IN THE LOWER ELEVATIONS BY THU. LITTLE WIND
OR WEATHER UNDER THE HIGH PRESSURE. MAIN THREAT COULD BE FOG OR
STRATUS...BUT WE ARE NEARLY OUT OF SEASON NOW THAT IT IS MARCH.
MESSICK

LONG TERM...FRIDAY THROUGH TUESDAY NIGHT. GFS AND ECMWF GOING BACK
AND FORTH WITH THE TROF/NON-TROF FRI NIGHT. FIRST THE GFS HAS THE
TROF MOVING THRU NE ID FRI NIGHT...THE ECMWF DOES NOT. NEXT NIGHT
THE SITUATION IS REVERSED. THIS CYCLE...ANOTHER REVERSAL. WILL STAY
THE COURSE AND KEEP SLIGHT CHANCE ALONG THE DIVIDE AND WY BORDER FRI
NIGHT AND SAT. EVEN THE WORST CASE SCENARIO DOES NOT AMOUNT TO MUCH.
THE REST OF THE FCST PERIOD IS DOMINATED BY THE UPPER RIDGE OVER THE
WEST...WHICH MEANS DRY AND WARM CONDITIONS. HEDGES

AVIATION...SNOW IS SPREADING FROM N TO S ACROSS ERN ID EARLY THIS
MORN AS A NORTHERN STREAM UPPER TROF DROPS IN FROM THE N. IFR
CIGS/VIS CAN BE EXPECTED THIS MORNING AT KIDA AND KPIH...WITH LESS
IMPACTS AT KBYI AND KSUN. CONDITIONS EXPECTED TO IMPROVE AT KIDA
THIS AFTN...BUT A CONVERGENCE ZONE IN THE LOWER SNAKE PLAIN/EASTERN
MAGIC VALLEY MAY RESULT IN LINGERING SNOW AND IFR CONDITIONS INTO
THE EVE. HEDGES

936 AM MST TUE MAR 3 2015

.DISCUSSION...NORTHERLY FLOW WILL CONTINUE TODAY OVER THE REGION
WITH DRIER AIR AND RAPID CLEARING BEHIND YESTERDAYS COLD FRONT.
BREEZY CONDITIONS CONTINUING TODAY WITH WIND GUSTS UP TO 30KT
DURING THE AFTERNOON. WINDS SHOULD DECREASE AFTER SUNSET WITH THE
DECOUPLING OF THE ATMOSPHERE. A SURFACE CONVERGENCE ZONE IS
PRESENT IN THE EASTERN MAGIC VALLEY TOWARDS POCATELLO. THIS IS
REFLECTED NICELY IN THE CURRENT FORECAST. NO UPDATES PLANNED.

&&

.AVIATION...VFR WITH SCT/BKN HIGH CLOUDS. MVFR CONDITIONS POSSIBLE
BETWEEN 18-21Z AT KTWF/KJER AS A BAND OF SNOW SHOWERS MOVES SOUTHWEST.
SURFACE WINDS 10-15 KTS WITH GUSTS UP TO 30 KTS IN THE SNAKE RIVER AND
BAKER VALLEYS. WINDS ALOFT NEAR 10K FT MSL...NNW 20-30KT...DROPPING
OFF TO NNW 10-20KT BY 12Z/WED.

.PREV DISCUSSION...
SHORT TERM...COLD FRONT FROM THE NORTHWEST BROUGHT SCATTERED LIGHT
SNOW SHOWERS TO IDAHO MOUNTAIN ZONES DURING THE NIGHT.  WEB CAMS
SHOWED SNOW SHOWERS NORTH OF BOISE AT BOTH BOGUS BASIN AND HORSESHOE
BEND HILL...AND ALSO AT MCCALL/ID.  KCBX RADAR TRACKED SNOW SHOWERS
BOTH NORTH AND SOUTH OF THE SNAKE BASIN...AND EVEN A FEW FLAKES IN
THE TREASURE VALLEY.  BOGUS BASIN RECEIVED ABOUT AN INCH OF NEW SNOW
BUT OTHER MOUNTAIN SITES GOT A DUSTING AT MOST...ALTHOUGH RADAR
SUGGESTED A LITTLE MORE IN THE OWYHEE MOUNTAINS.  THE FRONT ALSO
BROUGHT SUSTAINED NORTHWEST WINDS 15 TO 30 MPH WITH GUSTS 35 TO 40
MPH.  AT 10Z BOTH THE FRONT AND STRONGEST WINDS WERE IN THE EASTERN
UPPER TREASURE VALLEY AND WESTERN MAGIC VALLEY.  THOSE AREAS WILL
HAVE THE STRONGEST WINDS TODAY...JUST BELOW ADVISORY LEVELS.  ERN-
MOST ZONES WILL ALSO HAVE A CHANCE OF LIGHT SNOW SHOWERS TODAY...
THESE SHOULD END BY SUNSET.  AIR MASS WILL BE DRIER TODAY UNDER
STRONG NORTHERLY FLOW ALOFT.  SURFACE WINDS WILL DECREASE TONIGHT
AND WITH CLEAR SKIES AND DRY AIR TEMPS WILL BE NOTICEABLY COLDER...
BUT NOT QUITE AS COLD AS FORECAST BY PREVIOUS MODELS.  MET MOS
GUIDANCE NOW LOOKS TOO COLD FOR TONIGHT...MAV GUIDANCE PREFERRED.
BRIGHT SUNSHINE AND CONTINUED COOL WEDNESDAY BUT WITH MUCH LESS
WIND AS COASTAL UPPER RIDGE BEGINS TO NOSE INLAND.

LONG TERM...WEDNESDAY NIGHT THROUGH TUESDAY. UPPER LEVEL HIGH WITH
ITS AXIS STAYING ROUGHLY OVER CALIFORNIA WILL DOMINATE THE MID-LONG
TERM. A WEAK SHORTWAVE THAT THE ECMWF HAD BEEN HINTING AT FOR FRIDAY
IS NO LONGER VISIBLE IN THE LATEST RUN...WHICH IS MORE IN LINE WITH
THE DRIER GFS.  THEREFORE CONFIDENCE IS HIGH IN DRY CONDITIONS
THROUGH THE ENTIRE PERIOD. TEMPERATURES ARE EXPECTED TO GRADUALLY
RISE TO 10 PLUS DEGREES ABOVE NORMAL FOR SATURDAY AND BEYOND.

MEANWHILE A LOW PRESSURE SYSTEM PASSING SOUTH OF THE REGION WILL
BRING SOME LIGHT SNOW TO EXTREME SOUTHEAST IDAHO...AROUND THE SODA

AMOUNTS HAVE BEEN FLUCTUATING QUITE A BIT. LATEST MODELS DID COME
DOWN A LITTLE ON THE AMOUNTS...BUT STILL LOOKING AT 1 TO 3 INCHES OF
SNOW ACROSS THE EASTERN SNAKE PLAIN AND EASTERN HIGHLANDS. WIND
GUSTS OF 20 TO 25 MPH ARE POSSIBLE WITH THE FRONT AS WELL WHICH
COULD CREATE SOME BLOWING AND DRIFTING ISSUES. WILL CONTINUE THE

.DISCUSSION...A COLD FRONT NOW OVER WASHINGTON AND NW MONTANA WILL
MOVE SOUTHWARD AND REACH THE FORECAST AREA LATER THIS AFTERNOON IN
THE NORTHERN ZONES. COLD FRONT WILL MOVE THROUGH THE FORECAST AREA
BETWEEN 00-06Z FROM NW TO SE. STRONGEST WINDS ALOFT MOVE OVER THE
SNAKE PLAIN AROUND 09Z WITH SPEEDS BELOW ADVISORY LEVELS.
PRECIPITATION WILL BE LIMITED MOSTLY TO THE HIGHER TERRAIN WITH
THIS SYSTEM. CURRENT FORECAST LOOKS ON TRACK WITH NO UPDATES
PLANNED.

&&

.AVIATION...VFR WITH SCT/BKN HIGH CLOUDS. SURFACE WINDS GENERALLY
LIGHT DURING THE DAY...PICKING UP TO 15-25 KTS OUT OF THE NW AFTER
03/00Z. MAX GUSTS UP TO 30 KTS IN THE MAGIC VALLEY. PASSAGE OF
SHORTWAVE WILL BRING SCATTERED SNOW SHOWERS TO THE WEST CENTRAL AND
BOISE MOUNTAINS 02/18Z - 03/12Z...INCLUDING MYL. WINDS ALOFT NEAR
10K FT MSL...NW 10-15 KTS...INCREASING TO 20-30 KTS AFTER 03/06Z.

.PREV DISCUSSION...
SHORT TERM...SHORT WAVE TROUGH NOW MOVING RAPIDLY DOWN THE COAST
BUT SOME OF THE ENERGY WILL COME THROUGH THE INTERIOR NORTHWEST
LATER TODAY AND TONIGHT.  AT 00Z THIS AFTERNOON THE ASSOCIATED
SURFACE COLD FRONT WILL EXTEND FROM NEAR MCCALL/ID THROUGH SRN
HARNEY COUNTY/OR.  BY 06Z THE FRONT WILL EXTEND FROM NEAR SALMON
THROUGH TWIN FALLS TO NEAR ELKO/NV. THE FRONT WILL BRING SCATTERED
SNOW SHOWERS...ESPECIALLY TO NRN MOUNTAIN ZONES.  NORTHERLY FLOW
ALOFT OFTEN BRINGS LIGHT PCPN INTO THE SNAKE BASIN SO WE WILL ADD A
SLIGHT CHANCE OF SNOW SHOWERS THERE FOR TONIGHT.  FRONT AND SNOW
SHOWERS WILL EXIT OUR ERN AND SERN-MOST ZONES TUESDAY.  BEHIND THE
FRONT IS A COLDER AND DRIER AIR MASS UNDER STRONG NORTHERLY FLOW
ALOFT.  MOMENTUM ALOFT WILL MIX DOWN TO THE SURFACE RESULTING IN
GUSTY NORTHWEST SURFACE WINDS LATE TONIGHT THROUGH TUESDAY.
STRONGEST WINDS SHOULD BE IN THE UPPER TREASURE VALLEY AND WESTERN
MAGIC VALLEY BUT BELOW ADVISORY SPEEDS.

LONG TERM...TUESDAY NIGHT THROUGH MONDAY...A COOLER AND DRY
NORTHERLY FLOW WILL REMAIN IN PLACE WEDNESDAY...KEEPING TEMPERATURES
BELOW NORMAL. HOWEVER...A UPPER LEVEL RIDGE WILL AMPLIFY AND THE
AXIS IS EXPECTED TO REMAIN NEAR CALIFORNIA THROUGH THE WEEKEND. THIS
WILL TREND TEMPERATURES TO ABOVE NORMAL AND KEEP CONDITIONS DRY. THE

LATER TODAY AND TONIGHT.  AT 00Z THIS AFTERNOON THE ASSOCIATED
SURFACE COLD FRONT WILL EXTEND FROM NEAR MCCALL/ID THROUGH SRN
HARNEY COUNTY/OR.  BY 06Z THE FRONT WILL EXTEND FROM NEAR SALMON
THROUGH TWIN FALLS TO NEAR ELKO/NV. THE FRONT WILL BRING SCATTERED

ALOFT OFTEN BRINGS LIGHT PCPN INTO THE SNAKE BASIN SO WE WILL ADD A
SLIGHT CHANCE OF SNOW SHOWERS THERE FOR TONIGHT.  FRONT AND SNOW

FRONT IS A COLDER AND DRIER AIR MASS UNDER STRONG NORTHERLY FLOW
ALOFT.  MOMENTUM ALOFT WILL MIX DOWN TO THE SURFACE RESULTING IN
GUSTY NORTHWEST SURFACE WINDS LATE TONIGHT THROUGH TUESDAY.
STRONGEST WINDS SHOULD BE IN THE UPPER TREASURE VALLEY AND WESTERN

NORTHERLY FLOW WILL REMAIN IN PLACE WEDNESDAY...KEEPING TEMPERATURES
BELOW NORMAL. HOWEVER...A UPPER LEVEL RIDGE WILL AMPLIFY AND THE
