NO SIGNIFICANT IMPACTS FOR THE NEXT WEEK ARE EXPECTED. WILL
HAVE RECORD OR NEAR RECORD WARMTH WEDNESDAY THROUGH FRIDAY WITH
VALLEY HIGHS IN THE 70S TO LOWER 80S AND MOUNTAINS MAINLY 60S
INTO THE 70S. WILL BE SOME BREEZY AFTERNOONS WITH THE STRONGEST
20 TO 35 MPH IN THE SNAKE RIVER PLAIN. THE NEXT SLIGHT CHANCE OF
PRECIPITATIONS WILL BE IN THE MOUNTAINS ON SATURDAY AND SUNDAY.
WE WILL GET A COLD FRONTAL PASSAGE WITH ABOUT A 10 TO 15 DEGREE
COOLING SATURDAY INTO SUNDAY BUT TEMPERATURES WILL STILL BE
WELL ABOVE SEASONAL NORMAL WITH 50S MOUNTAINS AND 60S VALLEYS.
BY NEXT TUESDAY, A CHANCE FOR MORE WIDESPREAD PRECIPITATION BUT
VERY LOW CONFIDENCE THAT FAR OUT.

GUSTY WIND APPEARS TO HOLD OFF UNTIL MID-AFTERNOON WHEN THETA-E
PROFILE GETS INVERTED. AND GUSTINESS LOOKS CONSIDERABLY LESS FOR
KSUN AND KBYI, WHERE IT STRUGGLES TO GET TO 20KT ABOVE THE
BOUNDARY LAYER. CLOUDS WILL EVENTUALLY CLEAR OUT, WITH EVEN KDIJ
CLEARING BY 18/09Z TONIGHT; EVERYONE ELSE IS SOONER.
WIND GETS SUPER LIGHT DURING THE LATE NIGHT HOURS, ALTHOUGH KPIH
APPEARS TO HAVE A CONSISTENT NORTHEAST DRAINAGE WIND. KDIJ
APPEARS TO HAVE ENOUGH IN THE BOUNDARY LAYER TO KEEP ELEVATED
TONIGHT AT AROUND 10KT, MOSTLY FROM THE SOUTH. LOOKS LIKE LITTLE
CHANCE FOR WIND AT KSUN TO HAVE A SOUTHERLY COMPONENT, THE FLOW
ALOFT IS NORTHWESTERLY AND IT OVERWHELMS ANY SLOPE-VALLEY
INTERACTION WITH SOME 20KT IN THE BOUNDARY LAYER FROM THAT
DIRECTION. HOWEVER, NOT A WHOLE LOT OF CLOUD COVER AND WOULD NOT
BE SURPRISED TO SEE A SHIFT TO SOUTHEAST IF IT TAKES A WHILE FOR
THE MORNING INVERSION TO BREAK. THE THETA-E PROFILE INVERTS
BY 17/20Z, SO I HAVE HOPE.
PIH WATCHES/WARNINGS/ADVISORIES
NONE.
