AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE POCATELLO ID
213 PM MDT TUE JUN 3 2014

.SHORT TERM...TONIGHT THROUGH FRIDAY. SAT IMAGERY SHOWS SHORTWAVE
WORKING THROUGH OREGON THIS AFTERNOON. CONVECTION HAS REDEVELOPED
FROM THE CENTRAL MOUNTAINS ALONG THE DIVIDE WITH A FEW CELLS
EXTENDING INTO THE UPPER SNAKE PLAIN. BELIEVE STORMS WILL REMAIN
SUB SEVERE THOUGH A FEW STRONGER CELLS WITH HALF INCH HAIL AND
WIND GUSTS AROUND 40 MPH POSSIBLE. A FEW WEAK CELLS BEGINNING TO
SHOW UP IN THE SOUTHERN AND EASTERN HIGHLANDS AS WELL. BELIEVE
CURRENT TREND TO CONTINUE WITH STRONGEST CONVECTION TO THE NORTH
THROUGH THE EVENING THOUGH MODELS CONTINUE TO INDICATE ANOTHER
BATCH OF CONVECTION WORKING INTO THE REGION FROM NORTHERN NEVADA
LATER THIS AFTERNOON INTO THE EVENING. CONVECTION COULD CONTINUE
OVERNIGHT AS OREGON SHORTWAVE CONTINUES TO ADVANCE ON EASTERN
IDAHO. SHORTWAVE PASSAGE DURING THE DAY ON WEDNESDAY WITH
CONVECTION LIMITED TO THE EASTERN HIGHLANDS DURING THE DAY AS MORE
STABLE AIR WORKS INTO THE REGION WITH NORTHWEST FLOW. EASTERN
IDAHO DOES REMAIN UNDER THE INFLUENCE OF WEAKLY CYCLONIC FLOW WITH
TROUGHING OVER GREAT BASIN. SHORTWAVE DROPS THROUGH PACNW INTO
EAST IDAHO FOR THURSDAY BUT MODELS INDICATING MAINLY DRY FLOW AT
THIS TIME SO HAVE VERY WEAK POPS AT BEST WITH NO MENTION OF
THUNDER WEDNESDAY NIGHT THROUGH EARLY THURSDAY. SOME DIFFERENCES
IN THE MODELS AT THIS POINT AS NAM IS SLIGHTLY FASTER WITH NEXT
SHORTWAVE MOVING THROUGH THE PACNW THURSDAY NIGHT INTO FRIDAY.
BOTH MODELS DEVELOP CONVECTION ASSOCIATED WITH THE SHORTWAVE. BUT
SINCE TIMING IS SOMEWHAT IN QUESTION OPTED FOR BROAD BRUSHING WEAK
POPS ALONG DIVIDE AND EASTERN BORDER LATE THURSDAY INTO FRIDAY
WITH STRONGER POPS ALL HIGHER ELEVATIONS FRIDAY AFTERNOON AND
EVENING.

.LONG TERM...FRIDAY NIGHT THROUGH TUESDAY. MODEL DIFFERENCES
BECOME MORE ENHANCED MOVING INTO THE EXTENDED. OPTED TO MAKE NO
CHANGES TO SATURDAY AND BEYOND AS GFS AND ECMWF GRADUALLY BECOME
OUT OF PHASE. ECMWF SIGNIFICANTLY STRONGER AND FASTER WITH UPPER
LOW/SHORTWAVE MOVING OUT OF BC CANADA SATURDAY NIGHT WHILE GFS
HOLDS ON TO RIDGE ALONG PACIFIC COAST. ECMWF SOLUTION WOULD LEAD
TO PASSAGE OF STRONGER TROUGH MONDAY WITH COOLER TEMPS TUESDAY WHILE
GFS TRIES TO BRING WEAK SHORTWAVE TROUGH INTO THE GREAT BASIN FROM
NORTHERN CALIFORNIA. WILL LEAVE WEAK POPS OVER HIGHER ELEVATIONS
WITH TEMPS A BLEND OF GUIDANCE.

&&

.AVIATION...GUSTY WINDS CONTINUE THROUGH THE SNAKE PLAIN MAINLY
IMPACTING KIDA/KPIH THIS AFTERNOON AND EARLY EVENING. TSTORMS HAVE
DEVELOPED NORTH OF A LINE FROM KSUN-KIDA THIS AFTERNOON THOUGH
CONVECTION STILL POSSIBLE FOR MOST HIGHER ELEVATION AREAS IN THE
REGION. WILL MAINTAIN VCTS AT KSUN THROUGH EARLY EVENING BUT
BELIEVE THE SNAKE PLAIN TERMINALS WILL REMAIN DRY AT THIS TIME.

&&

.PIH WATCHES/WARNINGS/ADVISORIES...
LAKE WIND ADVISORY UNTIL 9 PM MDT THIS EVENING IDZ021.
