AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE POCATELLO ID
132 PM MDT SAT MAY 24 2014

.SHORT TERM...TONIGHT THROUGH TUESDAY. THE UPPER LOW OVER AZ IS
INCHING TOWARD THE 4-CORNERS AREA TODAY AS A NORTHERN STREAM UPPER
TROF MOVES THRU NORTHERN ID. THE COLD POOL WITH THE SOUTHERN
STREAM UPPER LOW WILL PROVIDE ENOUGH INSTABILITY FOR ISOLD TSTMS
IN THE SE PART OF THE FCST AREA...WHILE THE NORTHERN STREAM TROF
WILL PROVIDE SUPPORT FOR SCT TSTMS IN THE CENTRAL MTNS AND UPPER
SNAKE HIGHLANDS. TSTMS WILL DIMINISH THIS EVENING. BOTH UPPER
SYSTEMS MOVE FAR ENOUGH AWAY FROM ID ON SUNDAY TO REDUCE THE TSTM
THREAT TO A FEW NEAR THE DIVIDE. A NEW UPPER LOW APPROACHES THE
PAC NW COAST ON MON...SETTING UP STRONGER SW FLOW OVER ID. THIS
COULD SET OFF ISOLD TSTMS MON AFTN OVER THE CENTRAL MTNS WHILE THE
REST OF THE AREA REMAINS DRY. AS THE UPPER LOW MOVES CLOSER TO THE
COAST ON TUE...TSTM CHANCES INCREASE OVER THE CENTRAL MTNS.

GUSTY SW WINDS THIS AFTN WILL SETTLE DOWN THIS EVE. WARM TEMPS
WILL CONTINUE. HEDGES

.LONG TERM...TUE NIGHT THROUGH NEXT SAT NIGHT. 500MB LONGWAVE
FORECAST STARTS ZONAL BUT QUICKLY TRANSITIONS TO A WEST COAST TROUGH
AND A GREAT PLAINS RIDGE. THE JETSTREAM EXPECTED TO BE SHOVED WELL
INTO CANADA AND MAINLY A WARM AND SUMMER-LIKE PATTERN TO DEVELOP
OVER THE CONUS. MOST OF THE GULF OF ALASKA LOWS/SHORTWAVES SHOULD BE
HEADED INTO CENTRAL AND NORTHERN CANADA. THER IS ONE INTENSE
SHORTWAVE DURING THIS PERIOD THAT ENTERS THE WEST COAST...BUT BOTH
THE GFS AND ECMWF KEEP THE MOISTURE OUT OF CENTRAL AND SOUTHERN
IDAHO AS IT HEADS NORTHEASTWARD. A SLIGHT CHANGE IN THIS WAVE
TRAJECTORY COULD CHANGE THE FORECAST FOR SOUTHEAST IDAHO
CONSIDERABLY...BUT RIGHT NOW BOTH OPERATIONAL GUIDANCE PRODUCTS ARE
IN GOOD AGREEMENT ON THIS TRACK. SO THE ONLY WAY PRECIPITATION
SHOULD GET INTO THE GEM STATE WOULD BE THROUGH A SURGE FROM THE
SUBTROPICS WITH AN ENHANCED SOUTHERLY UPPER LEVEL FLOW...SOMETHING
THAT MID-RANGE GUIDANCE DOES NOT NORMALLY CATCH VERY WELL. IN THE
LAST 36 HOURS THERE IS A POSSIBILITY THAT THIS RIDGE WILL START TO
BREAK DOWN WITH A SOMEWHAT VIGOROUS TROUGH FRI/FRI NIGHT/SAT/SAT
NIGHT PROVIDING THAT SOUTHERLY SUBTROPICAL FLOW PRIOR TO ITS
ARRIVAL...BUT UNCERTAINTY IS VERY HIGH FOR THE TIMING OF A FEATURE
THAT FAR IN THE FUTURE. MESSICK

&&

.AVIATION...WEAK SURFACE LOW GENERATING SOME CONVERGENCE IN THE
NORTH END OF THE SNAKE RIVER PLAIN THIS AFTERNOON...ENOUGH TO
THREATEN SOME ISOLATED TS...WITH BARELY ENOUGH MOISTURE...SO TS WITH
ERRATIC GUSTY WIND THE BIGGEST THREAT TO AIRCRAFT TODAY...EXCEPT FOR
KBYI. AIR EXPECTED TO REMAIN STABLE ENOUGH IN THE EASTERN MAGIC
VALLEY TO PRECLUDE ANYTHING MORE THAN GUSTY WIND MIXING DOWN TO THE
SURFACE. MESSICK

&&

.FIRE WEATHER...SHORTWAVE FEATURE PUSHING THROUGH EAST IDAHO TODAY.
SOME INSTABILITY MAINLY EASTERN HIGHLANDS AND CENTRAL MOUNTAINS
TODAY SO LOOKING FOR SCATTERED SHOWERS AND THUNDERSTORMS MAINLY THIS
AFTERNOON. WINDS SHIFT WESTERLY TODAY BEHIND COLD FRONT PASSAGE
EARLY THIS MORNING.  INCREASED HUMIDITIES AND SLIGHTLY COOLER TEMPS
FOR TODAY BEHIND THIS FRONT. DRIER CONDITIONS FOR SUNDAY AHEAD OF
SLOWLY INCREASING INFLUENCE OF NEXT PACIFIC TROUGH HEADING INTO NEXT
WEEK. DMH

.PIH WATCHES/WARNINGS/ADVISORIES...
