DISCUSSION
UNSETTLED WEATHER WILL MOVE OVER THE BURN LOCATION VERY
EARLY IN THE PREDAWN HOURS ON WEDNESDAY MORNING. EXPECT
OVERCAST SKIES WITH NUMEROUS SHOWERS THROUGHOUT THE
MORNING. THERE MAY BE A BRIEF LULL IN PRECIPITATION,
MOST LIKELY BETWEEN 10AM AND 2PM, HOWEVER SCATTERED SHOWERS WILL STILL
BE IN THE VICINITY OF THE BURN LOCATION. BETTER CHANCES OF RAIN MOVE
IN AFTER 2PM AND SCATTERED ACTIVITY WILL LAST THROUGH MIDNIGHT. WHILE A
DEEP INVERSION IS UNLIKELY ON WEDNESDAY DUE TO CLOUDS AND PRECIPITATION,
MIXING WILL NOT BE ALL THAT STRONG DUE TO CLOUD COVER. THE BEST OPPORTUNITY
FOR BURNING MAY COME IN THE PREVIOUSLY MENTIONED 10AM-2PM WINDOW IF SKIES
CAN BRIEFLY THIN AND PRECIPITATION STOPS.
