AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE POCATELLO ID
117 PM MST TUE JAN 19 2016

.SHORT TERM...TONIGHT THROUGH THURSDAY NIGHT. NEXT SURGE OF PAC
MOISTURE SHOWING UP ON RADAR MOVING INTO WESTERN ID EARLY THIS AFTN.
SNOW WILL SPREAD ACROSS ALL AREAS THIS EVE AS THE UPPER TROF MOVES
THRU THE PAC NW.  MOST SNOW WILL FALL IN THE WEST FLOW UPSLOPE
FAVORED AREAS OF WESTERN CUSTER AND BLAINE COUNTIES AS WELL AS
SOUTHEAST HIGHLANDS. THE CENTRAL MTNS CAN EXPECT 3 TO 6 INCHES OF
SNOW STARTING THIS AFTN AND TAPERING OFF WED AFTN. THE SOUTHEAST
HIGHLANDS CAN EXPECT 4 TO 7 INCHES BEFORE TAPERING OFF WED EVE. THE
SNAKE RIVER PLAIN SHOULD RECEIVE 1 TO 2 INCHES MOST AREAS...EXCEPT
FOR THE INTERSTATE CORRIDOR FROM POCATELLO TO BURLEY WHERE WARMER
TEMPS WILL RESULT IN A RAIN/SNOW MIX WITH MINIMAL ACCUMULATION.

AS THE UPPER TROF MOVES THRU THE PSC NW...WINDS WILL PICK UP AROUND
MIDNIGHT AND INCREAST THRU WED AFTN. THIS MAY RESULT IN SOME BLOWING
AND DRIFTING SNOW.

MAJOR UPPER RIDGING BUILDS IN BY THU...RESULTING IN DRY CONDITIONS
EXCEPT FOR ISOLD SNOW SHOWERS IN THE NORTHEAST CORNER. HEDGES

.LONG TERM...FRIDAY THROUGH TUESDAY. MAIN CONCERN WILL BE STORM
IMPACTING THE FORECAST AREA STARTING FRIDAY NIGHT...IF YOU PREFER
THE 12Z GFS TIMING...OR SATURDAY NIGHT BASED ON ECMWF TIMING. THE
12Z ECMWF AND GFS ARE AT ODDS STILL ON EVOLUTION OF UPPER PATTERN
WITH THE ECMWF FAVORING DEVELOPMENT OF A CLOSED LOW JUST OFF THE
CALIFORNIA COAST FRIDAY NIGHT WHILE THE GFS MAINTAINS AN OPEN WAVE
AND THUS A MORE PROGRESSIVE FLOW. A COUPLE GFS ENSEMBLE MEMBERS ARE
GOING FOR THE CLOSED LOW SOLUTION. DESPITE THESE DIFFERENCES IN THE
OPERATIONAL MODELS...BOTH GFS AND ECMWF FAVOR WIDESPREAD PRECIP OVER
THE FORECAST AREA ON SATURDAY AFTERNOON...THEN SHIFTING FOCUS TO THE
EASTERN HIGHLANDS SUNDAY AFTERNOON. SNOW LEVELS GENERALLY SUPPORT A
RAIN/SNOW MIX IN THE SNAKE PLAIN AND SNOW IN THE HIGH COUNTRY. MODEL
DISCREPANCIES A BIT MORE PRONOUNCED MONDAY NIGHT WITH AMPLITUDE OF
UPPER RIDGE BUILDING OVER THE WEST. HINSBERGER

&&

.AVIATION...CHALLENGE FOR THIS PERIOD WILL BE SYSTEM MOVING INTO
FORECAST AREA TONIGHT. INITIAL IMPACTS WILL BE SEEN AT KSUN AND KBYI
AS OUR WESTERN-MOST SITES. TEMPS SHOULD BE WARM ENOUGH AT KBYI FOR
PRECIP TO FALL AS RAIN. WINDS WILL BE INCREASING THROUGH THE NIGHT
AS THE SYSTEM DRAWS NEAR. FORECAST BUFR SOUNDINGS SHOW 40+ KT WINDS
DROPPING BELOW 2000 FT AND MAY PRODUCE LLWS...BUT FEEL SFC WINDS
SHOULD BE HIGH ENOUGH TO BE A MITIGATING FACTOR. MODELS ARE PUSHING
A SECOND WAVE OF PRECIP AROUND 12Z TOMORROW. LOOKED LIKE THIS WILL
MAINLY IMPACT KBYI...SO ADDED SNOW FOR A FEW HOURS TOMORROW MORNING.
SHOULD SEE WINDS INCREASING BY 12Z TOMORROW AS WELL ACROSS THE SNAKE
PLAIN TERMINALS...GUSTING AS HIGH AS 35 KTS. HINSBERGER

.PIH WATCHES/WARNINGS/ADVISORIES...
