.DISCUSSION...
A FEW THUNDERSTORMS LINGER TO THE SOUTH OF THE BURN SITE LATE THIS
EVENING AND WILL REMAIN THROUGH THE REST OF THE OVERNIGHT. SO
EXPECT DRY CONDITIONS AT THE BURN SITE...WITH CLEARING SKIES.
HUMIDITY RECOVERIES WILL NOT BE ALL THAT GREAT TONIGHT...PERHAPS
TOUCHING 55 OR 60 PERCENT. SOUTHWEST WINDS LATE THIS EVENING
SHOULD PERSIST OVERNIGHT AND REMAIN FAIRLY LIGHT. WINDS WILL TURN
MORE WESTERLY BY LATE SUNDAY MORNING AS RELATIVE HUMIDITIES
PLUMMET INTO THE LOWER TEENS. ANOTHER ROUND OF ISOLATED
THUNDERSTORMS WILL BE POSSIBLE TO DEVELOP NEAR THE BURN SITE
SUNDAY AFTERNOON...BUT ANTICIPATE BEST CHANCES WILL BE OFF TO THE
EAST. ANY CONVECTION THAT DOES DEVELOP ON SUNDAY WILL HAVE VERY
DRY SURFACE CONDITIONS TO DEAL WITH...SO THEY WILL MOSTLY BE DRY.
