AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE POCATELLO ID
849 AM MDT WED SEP 30 2009

.UPDATE...NO UPDATE TO CURRENT FCST WITH UPPER TROUGH DIRECTLY
OVERHEAD AS ADVERTISED. HAVE SEEN SNOW DROP CLOSE TO VALLEY FLOORS
WITH BRIEF CHANGEOVER ALREADY OVERNIGHT. CLEARING LINE TO THE WEST
PER IR SAT IMAGERY...AND EXPECT CLEARING TO HELP INCREASE WINDS IN
THE EASTERN MAGIC AND LOWER SNAKE PLAIN AND MTNS TO THE SOUTH
TODAY. WINDS STILL LOOK SHY OF ADVISORY CRITERIA SO HAVE CONTINUED
TO HOLD BACK ON HEADLINE. ONLY OTHER CAVEAT TO FCST IS SLOW
DEVELOPMENT OF CONVERGENCE EVENT IN UPPER VALLEY. WINDS HAVE
TURNED NORTHWEST AND QUITE GUSTY EXITING CENTRAL MTN VALLEYS WITH
SOUTHWEST WINDS STILL THROUGH MUCH OF PLAINS. RADAR LOOP SHOWS
WEAK BAND HAS DEVELOPED...AND WILL WATCH FOR CHANGE TO SNOW AND
POTENTIAL ADDITIONAL ACCUMULATIONS. OTHERWISE FORECAST LOOKS TO BE
IN GREAT SHAPE GIVEN COMPLEXITY OF UPPER LOW AND WILL CONTINUE TO
MONITOR AS THE DAY GOES ON. DMH

&&

.PREV DISCUSSION... /ISSUED 341 AM MDT WED SEP 30 2009/

DISCUSSION...THE POWERFUL STORM SYSTEM FORECAST TO AFFECT EASTERN
IDAHO IS UPON US THIS MORNING. A GOOD BAND OF RAIN AND MOUNTAIN
SNOW IS WORKING ACROSS THE FORECAST AREA AS OF 3AM MDT. FOR
TODAY...SNOW LEVELS WILL CONTINUE TO DROP WITH THE MOST OF THE
SNOW FALLING AT OR ABOVE 5500 FEET. FORECAST ACCUMULATIONS OF UP
TO 4 INCHES AT MIDDLE ELEVATIONS WITH 6 OR MORE POSSIBLE ABOVE
9000 FEET APPEARS TO BE ON TRACK...BASED ON SNOW ALREADY STICKING
ON GRASSY SURFACES ACROSS THE CENTRAL MOUNTAINS. SINCE THE GROUND IS
WARM...ANY ACCUMULATING SNOW WILL LIKELY MELT ONCE HEAVIER BURSTS
OF SNOWFALL END. AT THIS TIME...WILL CONTINUE TO HIGHLIGHT
EXPECTATIONS IN SPECIAL WEATHER STATEMENTS AND THE HWO.
ACCUMULATING SNOW IS NOT EXPECTED IN THE SNAKE PLAIN...ALTHOUGH WE
MAY SEE IT MIX WITH RAIN. THIS IS ESPECIALLY THE CASE WITH MORE
CONVECTIVE ACTIVITY LIKE THE CONVERGENCE ZONE EVENT THAT APPEARS
TO BE SETTING UP FOR PORTIONS OF THE UPPER AND LOWER SNAKE PLAIN
BY THIS AFTERNOON. THE OTHER STORY DURING THE DAYLIGHT HOURS WILL
BE THE WIND. BREEZY CONDITIONS WILL CONTINUE UNTIL THIS EVENING.
SUSTAINED WINDS OF 15 TO 30 MPH ARE FORECAST WITH HIGHER GUSTS.
THE STRONGEST WINDS SHOULD OCCUR ACROSS THE EASTERN MAGIC
VALLEY...THE SOUTHERN HIGHLANDS AND CANYONS/VALLEYS THAT EMPTY OUT OF THE
CENTRAL MOUNTAINS INTO THE SNAKE PLAIN. WHILE A LAKE WIND ADVISORY
APPEARS A SURE BET FOR AMERICAN FALLS RESERVOIR...THAT WAS NOT
QUITE THE CASE FOR A WIND EVENT ACROSS THE MAGIC VALLEY AND
SOUTHERN HIGHLANDS. WHILE THE MODELS AND LOCAL WIND SCHEME DOE SHOW WINDS
FLIRTING WITH THE LOWER END OF WIND ADVISORY CRITERIA...THERE IS
SOME QUESTION ON HOW MUCH SUNSHINE AND INSTABILITY WILL DEVELOP IN
THE AREA. WILL LET THE DAY SHIFT KEEP AN EYE ON IT AND PULL THE
TRIGGER ON SOMETHING IF NECESSARY. THE OTHER STORY WILL BE THE
COLD NIGHT FORECAST ACROSS EASTERN IDAHO TONIGHT. AS THE SYSTEM
CONTINUES TO MOVE EAST...COLD AIR WILL STILL BE POURING INTO THE
AREA. TEENS AND 20S WILL BE COMMON IN THE MOUNTAINS...WITH 20S AND
LOWER 30S FOR MUCH OF THE SNAKE PLAIN. WE HAVE UPGRADED THE FREEZE
WATCH TO A WARNING FOR THOSE AREAS. PARTS OF THE UPPER PLAIN MAY
SEE A HARD FREEZE WITH TEMPERATURES NEARING 25 DEGREES. THE
CURRENT FORECAST CALLS FOR LOWS IN THE 30 TO 35 DEGREE RANGE
ACROSS THE EASTERN MAGIC VALLEY...THEREFORE A FREEZE WATCH HAS
BEEN ISSUED ALLOWING THE DAY SHIFT TO DECIDE ON THE COURSE OF
ACTION FOR THAT REGION.

DRIER CONDITIONS ARE FORECAST FOR TOMORROW AND FRIDAY. SOME
LINGERING SHOWERS ARE EXPECTED MAINLY ACROSS THE EASTERN MOUNTAINS
THURSDAY...AND AHEAD OF THE NEXT SYSTEM ON FRIDAY ACROSS THE
CENTRAL MOUNTAINS. TEMPERATURES WILL REBOUND BUT NOWHERE NEAR THE
70S AND 80S AS OF LATE. HIGHS IN THE 40S AND 50S WILL BE COMMON
WITH SOME AREAS APPROACHING 60 ON FRIDAY. THURSDAY NIGHT WILL BE
ANOTHER COLD NIGHT ACROSS THE AREA WITH ANOTHER FREEZE ANTICIPATED
ACROSS PORTIONS OF THE SNAKE PLAIN AND POSSIBLY THE MAGIC VALLEY.

ANOTHER SLOW MOVING AND POWERFUL STORM WILL AFFECT THE REGION BY
THE WEEKEND. THE GFS AND ECMWF ARE SHOWING SOME GOOD AGREEMENT ON
THIS. WE HAVE DECIDED TO INCREASE POPS AND LOWER TEMPERATURES
BEGINNING ON SATURDAY. THIS APPEARS TO BE ANOTHER GOOD RAIN AND
MOUNTAIN SNOW PRODUCER. IT APPEARS THAT IT IS FINALLY FALL ACROSS
EASTERN IDAHO.   KEYES

AVIATION...WIDESPREAD SHOWERS AND IFR/MVFR CEILINGS OVER CENTRAL
IDAHO MOVING TO THE WYOMING LINE BY THIS EVENING. SNOW LEVELS NEAR
7000 FEET MSL THIS MORNING GRADUALLY LOWER TO NEAR 5800 FEET BY
EVENING. BREEZY SOUTHWEST WINDS 15 TO 25 MPH CONTINUE IN THE SNAKE
PLAIN AND SOUTH CENTRAL HIGHLANDS THROUGH 03Z. CLEARING EXPECTED ON
THURSDAY BUT SCATTERED CLOUDS MAY OBSCURE HIGHER MOUNTAINS TOPS
ALONG THE EASTERN HIGHLANDS. RS

FIRE WEATHER...PRECIPITATION BAND THIS MORNING ASSOCIATED WITH THE
LOW PRESSURE TROUGH CROSSING IDAHO EXTENDS FROM SALMON TO BURLEY AND
WILL MOVE INTO WYOMING BY EARLY EVENING. SHOWERS WILL LINGER NEAR
THE WYOMING BORDER THROUGH THURSDAY MORNING. SNOW LEVELS NEAR 7000
FEET WILL LOWER TO NEAR 5800 FEET BY LATE AFTERNOON. SNOW WILL ACCUMULATE
AROUND A HALF FOOT AT ELEVATIONS NEAR 9000 FEET WITH 1 TO 3 INCHES
MORE COMMON ON MIDDLE SLOPES. SOUTH AND WEST FACING SLOPES WILL SEE
FAIRLY WIDESPREAD PRECIPITATION WITH NEAR A QUARTER INCH LIQUID
WATER. BREEZY 15 TO 25 MPH WINDS WILL FOCUS FROM EASTERN MAGIC
VALLEY TO POCATELLO AND MUCH OF THE SOUTHERN SAWTOOTH FOREST. A
SHORT DRY PERIOD FOLLOWS THURSDAY AND FRIDAY BEFORE ANOTHER
SIGNIFICANT LOW PRESSURE SYSTEM COMES IN ON SATURDAY. RS
