AMPLIFYING TROUGH ALONG COAST WITH CUT OFF LOW OFF CALIFORNIA
COAST COMBINING WITH SLOWLY PROGRESSING STRONG SORTWAVE IN
WASHINGTON STATE. MONSOON SURGE EXTENDS NORTH INTO EASTERN IDAHO
WITH ANOTHER SHORTWAVE SLIDING NORTHEAST THROUGH GREAT BASIN. RADAR
SHOWING LINE OF LIGHT SHOWERS EASTERN PORTIONS BUT BELIEVE LITTLE
IS REACHING THE GROUND. CLOUD COVER KEEPING MUCH OF THIS REGION
CAPPED EARLY THIS AFTERNOON. BETTER INSTABILITY EXISTS FURTHER
NORTH IN CENTRAL MOUNTAINS AND ISOLATED THUNDERSTORMS ALREADY
DEVELOPING ACROSS THE REGION. MODELS INCLUDING RAP/HRRR CONTINUE
TO DEVELOP STRONGER THUNDERSTORMS ON NORTHERN EDGE OF CLOUD COVER
CONTINUING NORTH INTO CENTRAL MOUNTAINS THIS AFTERNOON AND
EVENING. WILL MAINTAIN SCATTERED CONVECTION BUT MIGHT BE OVERDONE
WITH THUNDER UNDER CURRENT CLOUD COVER. GREAT BASIN SHORTWAVE
EJECTS ACROSS SOUTHEAST CORNER TONIGHT WHICH SHOULD LEAVE MUCH OF
REGION IN WEAK UNSETTLED RIDGE OVERNIGHT. UPPER TROUGH SHIFTS EAST
INTO IDAHO THROUGH THE DAY WEDNESDAY FOR ANOTHER ROUND OF
CONVECTION. UPPER TROUGH BECOMES VERY SLIGHTLY NEGATIVELY TITLED
INTO THURSDAY WITH TROUGH AXIS DRAPED ACROSS WESTERN IDAHO. BOTH
GFS AND NAM SHOWING STRONG INDICATION THAT ENOUGH DRY AIR WILL
WORK INTO THE CENTRAL MOUNTAINS TO KEEP REGION DRY. LATEST WRINKLE
IN THE FORECAST HEADED INTO FRIDAY IS A RETURN TO THE SOLUTION OF
DEEP CUT OFF LOW OVER PACNW. NAM AND GFS DIFFER IN POSITION OF
CENTER OF LOW. NAM FURTHER NORTH AND MORE OPEN THAN
GFS...RESULTING IN MORE PRECIP ACROSS EAST IDAHO THAN PREVIOUS
RUNS. DMH

.LONG TERM...FRIDAY NIGHT THROUGH TUESDAY. MADE NO CHANGES TO
CURRENT FORECAST. ECMWF AND GFS IN BETTER AGREEMENT THIS
RUN...BOTH SUPPORTING SLOW PROGRESSION OF CLOSED LOW FROM PACNW
LATE FRIDAY THROUGH IDAHO INTO OPEN TROUGH IN NORTHERN PLAINS LATE
SUNDAY. CONVECTION REMAINS POSSIBLE EACH DAY OF THE WEEKEND. FLOW
FLATTENS SOMEWHAT SUNDAY NIGHT AHEAD OF NEXT WAVE DIVING SOUTH
ALONG THE CANADIAN DIVIDE. TROUGH AXIS IN PLACE MONDAY...SHIFTING
INTO NORTHERN ROCKIES BY TUESDAY. CURRENT GRIDS MAINTAIN POPS NEAR
CLIMO AND WILL LEAVE FOR NOW. DMH

&&

.AVIATION...SHOWERS AND STORMS WILL BE AROUND THROUGH TOMORROW AND
BEYOND. WE WILL CARRY AT THE VERY LEAST VCTS AND VCSH IN THE TAFS.
GUSTY WINDS OVER 30 KTS ARE ALSO POSSIBLE...AND LOCALLY HEAVY RAIN
WHICH COULD TEMPORARILY REDUCE VISIBILITY.  KEYES

&&

.FIRE WEATHER...THE POSSIBILITY OF SHOWERS AND ISOLATED/WIDELY
SCATTERED THUNDERSTORMS WILL CONTINUE THROUGH AT LEAST FRIDAY ACROSS
MOST OF EASTERN IDAHO. THE BEST PERIODS FOR ANY RAINFALL OVER 0.10
INCHES WILL BE THROUGH TOMORROW AND AGAIN ON FRIDAY. FRIDAY ALSO NOW
LOOKS LIKE THE BEST DAY FOR MORE WIDESPREAD ACTIVITY. GUSTY WINDS
OVER 35MPH AT TIMES ARE POSSIBLE WITH STRONGER STORMS AS WELL. WE
WILL SEE INCREASING SURFACE WINDS BUT HIGHER HUMIDITY SHOULD NEGATE
ANY CONCERNS FOR CRITICAL FIRE CONDITIONS. THE MODELS ARE NOW NOT
TRYING TO DRY OUT THE SOUTHERN FIRE DISTRICTS OVER THE WEEKEND AND
BACK TO WIDELY VARYING SOLUTIONS ON HOW TO HANDLE THE STORM SAGGING
INTO THE NORTHERN STATES. WE KEPT WITH THE PREVIOUS IDEA OF SOME
DRYING ACROSS THE SOUTH AND A LITTLE BETTER CHANCE OF RAIN ACROSS
THE CENTRAL MOUNTAINS AND UPPER SNAKE HIGHLAND.  KEYES

.PIH WATCHES/WARNINGS/ADVISORIES...
NONE.
