DISCUSSION
MOISTURE REMAINS IN PLACE OVER THE REGION TODAY, BRINGING
ANOTHER DAY OF HEIGHTENED CHANCES FOR SHOWERS AND THUNDERSTORMS
BUILDING OVER THE HIGH TERRAIN FEATURES SURROUNDING THE FIRE AREA.
STORMS ARE EXPECTED TO BE NEARLY STATIONARY, BUT WILL DRIFT OFF
TERRAIN FEATURES THROUGH THE AFTERNOON HOURS. SHOWERS AND
THUNDERSTORMS ARE EXPECTED TO BEGIN BUILDING OVER THE HIGH TERRAIN
AROUND 1200, POTENTIALLY NOT MOVING OFF THE TERRAIN UNTIL
1300-1400. STORMS WILL HAVE THE GREATEST CHANCE TO MOVE OVER THE
FIRE AREA BEFORE 1500-1600. A CHANCE FOR SHOWERS AND THUNDERSTORMS
WILL BE MAINTAINED THROUGH AROUND 1800-1900 BEFORE CONDITIONS
STABILIZE INTO THE EVENING HOURS. AS HAS BEEN THE CASE FOR THE
LAST SEVERAL DAYS, AFTERNOON STORMS WILL INTRODUCE THE RISK OF
LIGHTNING, GUSTY OUTFLOW WINDS, AND HEAVY RAINFALL. OUTSIDE OF ANY
OUTFLOW WINDS, THE FLOW OVER THE FIRE AREA WILL BE LIGHT AND
INFLUENCED BY TERRAIN FEATURES (SLOPE FLOWS).
