WINDS ARE EXPECTED TO START OUT THE MORNING OUT OF THE SOUTHEAST
TUESDAY MORNING...BECOMING EASTERLY BY NOON. BASED ON THE LAT/
LON GIVEN...IT APPEARS THAT THE PRESCRIBED BURN IS LOCATED EAST
OF LAKE TAWAKONI...SO THE FIRE/EMBERS SHOULD BE CARRIED TOWARDS
THE LAKE TOMORROW AFTER 10 AM. EASTERLY WINDS WILL BE MET WITH
AN INCREASE IN AFTERNOON RELATIVE HUMIDITY VALUES COMPARED TO
TODAY. TODAY`S MINIMUM AFTERNOON RELATIVE HUMIDITY SHOULD BE
RIGHT AROUND 30 PERCENT. TUESDAY`S PROJECTED MINIMUM RELATIVE
HUMIDITY IS EXPECTED TO BE AROUND 40 PERCENT.

THE INCREASE IN HUMIDITY MEANS AN INCREASE IN STORM CHANCES
DURING THE PEAK HEATING HOURS OF THE DAY TOMORROW AS WELL.
OVERALL...ISOLATED THUNDERSTORMS ARE EXPECTED ACROSS THE
REGION...BUT THE CHANCE OF A STORM DIRECTLY IMPACTING THE
PRESCRIBED BURN LOCATION IS ONLY 20 PERCENT AT THIS TIME.
