A LONG WAVE UPPER TROUGH WILL REMAIN ANCHORED OFFSHORE AND THE
VERY HOT RIDGE WILL NOW BE CENTERED SOUTHEAST OF IDAHO. THIS WILL
KEEP UNSETTLED CONDITIONS OVER CENTRAL IDAHO THROUGH THE WEEKEND.
THERE IS AN UPPER LEVEL DISTURBANCE ON WATER VAPOR IMAGERY THAT

WINDS FAR FROM STORMS AND HEAVY RAIN UNDERNEATH STORMS CORES.
ENOUGH LOW LEVEL MOISTURE WILL REMAIN NEAR OR JUST SOUTH OF THE
ROCK LAKE AREA TO KEEP A THREAT OF THUNDERSTORM AND ESPECIALLY
LATE DAY OUTFLOW BOUNDARIES THROUGH THE WEEKEND.
