DISCUSSION
SHOWERS WILL BE BOUNTIFUL FOR THE NEXT COUPLE OF DAYS DUE TO AN
UNSETTLED WEATHER PATTERN. THE BEST CHANCE FOR EMBEDDED
THUNDERSTORMS WITHIN THESE WIDESPREAD SHOWERS WILL BE TODAY AND
TONIGHT, BUT THE FREQUENCY OF THUNDERSTORM ACTIVITY WILL GRADUALLY
DECREASE THEREAFTER. THIS ENVIRONMENT IS UNFAVORABLE FOR FIRE
WEATHER, SO CONCERNS ARE VERY LOW AT THIS TIME.
