.SHORT TERM...CLEANER WEST/NORTHWEST WINDS HAVE SWEPT OUT MOST OF
THE SMOKE THAT COVERED SRN IDAHO THURSDAY.  TONIGHT THROUGH SUNDAY
WE SEE NO REPEAT OF SOUTHWEST WINDS ALOFT THAT WOULD BRING SMOKE
BACK IN FROM NRN CALIF.  LATE SATURDAY THROUGH SUNDAY UPPER WINDS
WILL BECOME SOUTHEAST AND THEN EASTERLY WHICH SHOULD KEEP OUR CWA
SMOKE-FREE.  THESE WINDS WILL BE DUE TO AN UPPER LOW APPROACHING
FROM SRN CALIF THROUGH NEVADA.  THIS IS THE SAME LOW THAT FORMED
OFF THE OREGON COAST AND MOVED SOUTH EARLIER THIS WEEK.  THE LOW
WILL TRACK ACROSS SRN IDAHO SUNDAY NIGHT WITH HIGHEST POPS IN
S-CENTRAL IDAHO BEGINNING SUNDAY.  POPS WILL BE LOWER TO THE
NORTH AND WEST...TO NEAR ZERO IN BAKER COUNTY/OR.  TEMPS WILL
CONTINUE ABOVE NORMAL THROUGH SUNDAY IN OREGON AND IN NRN-MOST
IDAHO ZONES.  COOLEST TEMPS...EVEN A LITTLE BELOW NORMAL...WILL
BE IN SOUTH-CENTRAL IDAHO SUNDAY UNDER THE CLOUDS AND SHOWERS.
INSTABILITY FOR A SLIGHT CHANCE OF THUNDERSTORMS WILL BE ALONG THE
NEVADA/IDAHO BORDER BUT WE WILL FORECAST A SLIGHT CHANCE AS FAR
NORTH AS THE BOISE MOUNTAINS.

.LONG TERM...SUNDAY NIGHT THROUGH FRIDAY...A WEAK UPPER LOW CENTERED
OVER SOUTHERN IDAHO ON SUNDAY NIGHT WILL DRIFT EAST ON MONDAY AND
INTO WYOMING ON TUESDAY. IT LOOKS LIKE THERE WILL BE ENOUGH MOISTURE
WRAPPING AROUND THE NORTHWEST SIDE OF THE LOW TO BRING SHOWERS AND
ISOLATED THUNDERSTORMS TO SOUTHERN IDAHO ON SUNDAY NIGHT AND
MONDAY...BUT EASTERN OREGON LOOKS DRY AT THIS TIME. WARM DRY WEATHER
IS EXPECTED ON TUESDAY AND WEDNESDAY WITH A RIDGE OVER THE AREA.  A
COLD FRONT IS EXPECTED TO APPROACH THE WESTERN IDAHO BORDER BY
THURSDAY AFTERNOON OR EVENING...BRINGING ANOTHER CHANCE OF SHOWERS
AND THUNDERSTORMS. COOLER WEATHER WILL FOLLOW THE FRONT ON FRIDAY.

&&

.AVIATION...VFR WITH MOSTLY CLEAR SKIES EXPECTED THROUGH SATURDAY.
SFC WINDS WILL BE LIGHT AND VARIABLE LESS THAN 10 KTS. UPPER LEVEL
WINDS WILL BE WESTERLY AT 15 TO 20 KTS. THE OUTLOOK FOR SUNDAY SHOWS
INCREASING HIGH CLOUDS WITH A CHANCE OF SHOWERS AND THUNDERSTORMS IN
SOUTHERN IDAHO.
