.DISCUSSION...

CLEARING SKIES OVER THE FIRE THIS MORNING WILL ALLOW FOR
ADDITIONAL DAYTIME HEATING TODAY. THIS WILL AID IN THE DEVELOPMENT
OF SHOWERS AND THUNDERSTORMS IN THE LATE MORNING AND AFTERNOON
HOURS. THE LOCATION OF THE FIRE HAS BEEN A FAVORITE FOR STORM
DEVELOPMENT OVER THE LAST COUPLE OF DAYS. STORMS TODAY ARE AGAIN
EXPECTED TO MOVE SLOWLY AND MAY PRODUCE PERIODS OF MODERATE TO
HEAVY RAINFALL IN ADDITION TO LIGHTNING AND GUSTY WIND. SOME
STORMS MAY BECOME STRONG...ESPECIALLY IN THE AFTERNOON
HOURS...WITH STRONGER WIND. OTHERWISE...STORMS SHOULD WEAKEN
OVERNIGHT. AFTERNOON STORM ACTIVITY ANTICIPATED FOR THE NEXT
COUPLE OF DAYS UNDER THE CURRENT PATTERN WITH GENERALLY LIGHT WIND
EXPECTED OUTSIDE OF STORM ENVIRONMENTS.
