.DISCUSSION...UPPER LOW IS SITTING OFF IN THE EAST PACIFIC JUST WEST
OF VANCOUVER ISLAND. WV IMAGERY SHOWS A COUPLE OF WEAK IMPULSES OF
ENERGY ROTATING OUT OF THE LOW. MODELS PROJECT LITTLE SENSIBLE
WEATHER ASSOCIATED WITH THESE IMPULSES...AND WEATHER SHOULD BE
RELATIVELY CLEAR ACROSS THE AREA TODAY. AS A RESULT...LOW LEVEL
LAPSE RATES WILL STEEPEN ALLOWING SOME OF THE STRONGER WINDS TO MIX
TO THE SURFACE THIS AFTERNOON. MOS GUIDANCE IS INDICATING STRONGER
WINDS THAN YESTERDAY AND WE WILL LIKELY SEE ADVISORY LEVEL WIND
SPEEDS THIS AFTERNOON ACROSS THE LOWER SNAKE RIVER PLAIN. DRY
WEATHER SHOULD CONTINUE THROUGH SATURDAY AS UPPER RIDGING MOVES
ACROSS THE AREA.

ON SUNDAY...MODELS DEPICT AN AMPLIFYING UPPER TROUGH DEVELOPING OVER
THE PACIFIC NORTHWEST...BUT CONTINUE TO PUSH MOST OF THE MOISTURE
OVER NORTHERN IDAHO AND WESTERN MONTANA. THEREFORE WE SHOULD SEE
LITTLE IN THE WAY OF POPS EARLY NEXT WEEK. THE 00Z GFS/ECMWF DROPS
AN UPPER TROUGH OVER THE UPPER SNAKE HIGHLANDS...WHICH MAY BE THE
ONLY AREA OF CONCERN IN THE EXTENDED PERIODS AS FAR AS POPS ARE
CONCERNED.  HINSBERGER
