...FIRE WEATHER WATCH FROM 10 AM MONDAY TO MIDNIGHT MDT MONDAY
NIGHT FOR DRY THUNDERSTORMS...LOW HUMIDITY AND OUTFLOW WINDS...

.DISCUSSION...EXPLOSIVE FIRE GROWTH POTENTIAL WILL EXIST THROUGH
TOMORROW EVENING AT LEAST. THE GOOD NEWS IS THAT WIND TRENDS WILL
BE DECREASING A BIT OVER THE NEXT 24 HOURS VERSUS WHAT HAS BEEN
REALIZED OVER THE LAST FEW DAYS. THIS SAID...NEAR SURFACE
SOUTHWESTERLY GUSTS ARE EXPECTED TO REACH NEAR 30 MPH AGAIN
TOMORROW AFTERNOON FOR A WINDOW DURING PEAK HEATING COUPLED WITH
HAINES INDICES REACHING HIGH LEVELS AT THAT TIME. MID LEVEL
MOISTURE WILL BE SEEPING IN FROM THE SOUTH TOMORROW AS WELL WITH
AFTERNOON BUILDUPS EXPECTED OVER THE TERRAIN. A SLIGHT CHANCE
EXISTS THAT AN ISOLATED CELL WILL MOVE OVER THE BURN SITE THAT

WINDS...BUT NO WETTING RAINS. MOISTURE WILL CONTINUE TO INCREASE
ON MONDAY WITH RH TRENDS CLIMBING SLIGHTLY OVER CRITICAL
LEVELS...BUT WITH THAT WILL COME A BETTER CHANCE OF THUNDERSTORMS
IN THE AFTERNOON. CANNOT RULE OUT THE CHANCE FOR WETTING RAINS AT
THIS TIME...BUT CONFIDENCE PLACES ONLY A 10 PERCENT CHANCE OF
THIS OCCURRING.
