IGNITION TIME. SLIGHTLY HIGHER MOISTURE AND INCREASED INSTABILITY ON
TUESDAY WILL LEAD TO SCATTERED SHOWERS OR THUNDERSTORMS OVER INTERIOR

IN THE AFTERNOON. MOST OF THE THUNDERSTORM ACTIVITY IS EXPECTED TO BE
CLOSER TO LAKE OKEECHOBEE DURING THE AFTERNOON BUT COULD SPREAD EAST
ACROSS PALM BEACH COUNTY AS THE AFTERNOON PROGRESSES.
