.DISCUSSION...THE UPPER LEVEL HIGH IS CENTERED ON THE COLORADO-
KANSAS BORDER BUT EXTENDS FROM SOUTHERN CALIFORNIA TO THE OHIO
RIVER VALLEY. THE DEEPEST MOISTURE IS TO THE WEST OF THE FIRE
SITE BUT THERE IS SUFFICIENT MOISTURE FOR A CHANCE OF AFTERNOON
AND EVENING STORMS. STORM MOTION WILL BE FROM THE SOUTHWEST TO
NORTHEAST AT 15 MPH SO STORMS INITIATING OVER THE ROAN PLATEAU
WILL THREATEN THE FIRE SITE THIS AFTERNOON. THE MAIN THREAT FROM
THESE STORMS IS LIGHTNING AND GUSTY OUTFLOW WINDS. STORMS WILL END
WITH SUNSET. MOISTURE DIMINISHES SOMEWHAT ON SATURDAY AND THE FLOW
ALOFT SHIFTS FROM SOUTHWEST TO WEST. THIS WILL DIMINISH THE
CHANCES OF THUNDERSTORMS. TEMPERATURES REMAIN WELL ABOVE NORMAL.
