FORECAST IS BASED ON IGNITION TIME OF 1030 EDT ON APRIL 12.
IF CONDITIONS BECOME UNREPRESENTATIVE, CONTACT THE NATIONAL WEATHER
SERVICE.

...RELATIVE HUMIDITIES DOWN TO AROUND 25 PERCENT THIS AFTERNOON...

.DISCUSSION...AS A COLD FRONT DISSIPATES NORTH OF THE AREA...HIGH
PRESSURE WILL BUILD BACK OVER EAST KENTUCKY RESULTING IN A
CONTINUATION OF OUR BOUT OF DRY AND WARM WEATHER. PLENTY OF
SUNSHINE AND A WELL MIXED ATMOSPHERE WILL ALLOW DRY AIR ALOFT TO MIX
DOWN DURING THE AFTERNOON TODAY RESULTING IN HUMIDITY LEVELS FALLING
TO NEAR 25 PERCENT. A SLIGHT INCREASE IN MOISTURE ON TUESDAY WILL
LIKELY KEEP HUMIDITIES FROM DROPPING TOO FAR BELOW 30 PERCENT. DUE TO
THE ATMOSPHERE MIXING TO SUCH A HIGH LEVEL ALOFT THIS AFTERNOON AND
TUESDAY AFTERNOON...THE SMOKE DISPERSION WILL BE FAVORABLE DESPITE
RELATIVELY LIGHT WINDS AT GROUND LEVEL.
