.DISCUSSION...

HIGH PRESSURE RIDGING WILL CONTINUE TO BUILD TODAY. A FEW MID AND
HIGH LEVEL CLOUDS WILL BE POSSIBLE BUT OTHERWISE EXPECT MOSTLY
SUNNY SKIES TODAY. TEMPERATURES WILL BE WARMER TODAY WITH
READINGS ABOUT 10 TO 15 DEGREES WARMER THAN MONDAY. WARMER AND
DRIER CONDITIONS WILL ALSO RESULT IN LOWER AFTERNOON HUMIDITIES
TODAY AS WELL. A SOUTHWEST FLOW ALOFT WILL BE OVER THE BURN SITE
WEDNESDAY AS A DISTURBANCE MOVES ONTO THE PACIFIC NORTHWEST COAST.
THIS WILL RESULT IN A SLIGHT CHANCE FOR A SHOWER OR THUNDERSTORM
WEDNESDAY AFTERNOON WITH BETTER CHANCES WEDNESDAY NIGHT.
TEMPERATURES WILL BE WARMER YET WEDNESDAY. HOWEVER...INCREASING
MOISTURE CHANCES WILL ALSO BRING HIGHER AFTERNOON HUMIDITIES.
