AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE POCATELLO ID
230 AM MST WED FEB 17 2016

.SHORT TERM...TODAY THROUGH FRI NIGHT. SATELLITE IMAGES INDICATE A
WELL DEVELOPED CLOUD LEAF HAS ENTERED THE PACIFIC NORTHWEST.
CLOUDS HAVE ALREADY STARTED TO PUSH INTO THE FORECAST
AREA...THOUGH ALMOST ALL HIGH LEVEL. DENSE FOG HAS DEVELOPED IN
ENOUGH AREAS TO CONTINUE THE FOG ADVISORY FOR THE UPPER SNAKE
RIVER PLAIN AND THE LOWER ELEVATIONS OF THE UPPER SNAKE HIGHLANDS.
THIS IS MAINLY DUE TO WARM AIR ADVECTION AS A CLASSIC OCCLUDED
WINTER STORM MOVES IN. INCREASING WIND SHOULD HELP DISSIPATE THE
FOG. PRECIPITATION SHOULD DEVELOP IN THE CENTRAL IDAHO
MOUNTAINS...BUT LATEST NAM/GFS MODEL RUNS INDICATE THAT
PRECIPITATION WILL HOLD OFF UNTIL THE EVENING HOURS. WOULD LIKE TO
BRING THE POPS FOR THIS AFTERNOON DOWN MORE SIGNIFICANTLY...BUT
HAVE COORDINATION ISSUES IF THEY ARE LOWERED ANY MORE. HEAVIEST
PRECIPITATION OCCURS THU MORNING...WITH CONTINUED MODERATE AMOUNTS
FOR THU AFTERNOON AND EVENING. THE COLD FRONT COMES THROUGH DURING
THE MIDDLE OF THE DAY ON THU...AND THUS THU HIGH TEMPERATURES WILL
BE OCCURING PRIOR TO NOON. TEMPERATURES GET COLD ENOUGH ON THU
NIGHT TO ALLOW EVEN THE EASTERN MAGIC VALLEY AND SNAKE RIVER PLAIN
TO RECEIVE SOME SNOW. SHOULD AMOUNT TO LESS THAN AN INCH AS THE
STORM IS BY THEN MOVING OUT OF EASTERN IDAHO. THERE IS NOT MUCH OF
A BREAK BEFORE A WEAKER LOW MOVES IN AND BY FRI NIGHT
PRECIPITATION WILL HAVE SPREAD INTO THE CENTRAL IDAHO MOUNTAINS
AND THE UPPER SNAKE HIGHLANDS. TEMPERATURES EACH DAY DURING THIS
PERIOD WILL BE GETTING ABOVE THE MELTING POINT. THIS MAY KEEP FOG
GOING...BUT WITH ENOUGH PRECIPITATION EXPECTED THAT DENSE FOG IS
NOT REALISTIC. THE WIND WITH THE COLD FRONT ON THU HAVE THE
POTENTIAL TO BE AT LEAST ADVISORY LEVEL...BUT WILL HOLD OFF ON
ISSUING ANYTHING THIS MORNING AS THE FOG ADVISORY IS IN EFFECT.
MESSICK

.LONG TERM...SATURDAY THROUGH NEXT WEDNESDAY. THE GFS AND ECMWF WERE
IN FAIRLY GOOD AGREEMENT THIS MORNING SHOWING A NEGATIVELY TILTED
PAC TROUGH SWEEPING EAST THROUGH THE REGION EARLY SATURDAY MORNING
WITH IMPROVING CONDITIONS ADVANCING FROM WEST TO EAST ACROSS THE
AREA SATURDAY AFTERNOON AS A TRANSIENT SHORT-WAVE RIDGE SHIFTS INTO
THE AREA. DRY CONDITIONS ARE EXPECTED SUNDAY AS A SECOND PAC TROUGH
ROTATES INTO THE NW COAST. THE ECMWF DRIVES THIS WAVE EAST ALONG THE
CANADIAN BORDER AND THEN SE ALONG THE CONTINENTAL DIVIDE SUNDAY
NIGHT/MONDAY WITH ATTENDING SNOWFALL IMPACTING THE MONTANA/WYOMING
BORDER REGIONS. THE GFS WAS A LITTLE DEEPER AND STRONGER WITH THE
PASSING WAVE RESULTING IN BROADER COVERAGE OF SNOWFALL. AN AMPLIFIED
UPPER RIDGE IS EXPECTED TO BUILD OVER THE REGION IN THE WAKE OF THIS
EXITING SYSTEM MONDAY NIGHT/TUESDAY RESULTING IN DRY CONDITIONS
THROUGH TUESDAY NIGHT. A THIRD PAC SYSTEM LIFTS INTO THE NW COAST
WEDNESDAY MORNING ROTATING OVER THE TOP OF THE RIDGE INTO CNTRL
IDAHO LATE WEDNESDAY AFTERNOON/EVE FOR A SLIGHT RISK OF SNOWFALL
ACROSS THE CNTRL AND NE MOUNTAINS. ABOVE NORMAL DAYTIME HIGHS ARE
EXPECTED TO CONTINUE THROUGHOUT THE PERIOD. HUSTON
&&

.AVIATION...A PAC LOW WAS APPROACHING THE NW COAST EARLY THIS
MORNING WHILE ACCOMPANYING MID AND UPPER CLOUDS ADVANCED INLAND
ACROSS OREGON INTO WRN IDAHO. NUMERICAL MODELS SHOW THE LOW MOVING
INLAND TONIGHT WITH THE LEADING EDGE OF LOWER CLOUDS AND PRECIP
SPREADING INTO KSUN AND KBYI AROUND 06Z AND THE REMAINDER OF SE
IDAHO BETWEEN 09Z AND 12Z PRODUCING MVFR/IFR CIGS. IN THE MEAN
TIME...LIFR VIS/CIGS ASSOCIATED WITH FOG WERE IMPACTING KPIH AND
KIDA EARLY THIS MORNING AND THE EXPECTATION AT THIS TIME IS THAT
THESE CONDITIONS WILL NOT HOLD FOR LONG AS ALL THE MID AND HIGH
CLOUDS ADVANCE INTO THE AREA. HUSTON
