.DISCUSSION...A STRONG UPPER LEVEL LOW IS CURRENTLY SPINNING OVER
SOUTHWEST IDAHO AND DRIFTING VERY SLOWLY TO THE EAST. AS THE LOW
TRACKS THROUGH IDAHO THE CHANCE OF SHOWERS AND THUNDERSTORMS WILL
INCREASE THROUGHOUT THE NIGHT OVER THE UNIT. PRESENTLY THERE IS A
LINE OF SHOWERS AND THUNDERSTORMS WHICH SPANS FROM JUST SOUTHEAST
OF SALMON/IDAHO NORTHEAST TO SHOUP/IDAHO OR APPROXIMATELY 40 MILES
SOUTHWEST OF THE BURN SITE. THIS LINE OF STORMS IS MOVING TO THE
NORTH AT APPROXIMATELY 35 MPH...LIKELY PASSING JUST TO THE WEST OF
UNIT WITHIN THE HOUR. BUT FURTHER DEVELOPMENT OF THIS LINE TO THE
EAST CANNOT BE RULED OUT AND IS CURRENTLY BEING SEEN ON RADAR NEAR
BANNACK. VERY HEAVY RAINFALL ALONG WITH FREQUENT LIGHTNING AND
SMALL HAIL HAVE BEEN COMMON WITH THIS LINE OF THUNDERSHOWERS.

SIMILAR CONDITIONS ARE EXPECTED TO CONTINUE THIS EVENING AS WAVES OF
SHOWERS AND THUNDERSTORMS ROTATE FROWARD FROM THE UPPER LOW. THE
CHANCE OF THUNDERSTORMS WILL DECREASE AFTER MIDNIGHT BUT PROSPECTS
FOR HEAVY RAIN SHOWERS WILL REMAIN THROUGH MONDAY MORNING.
