SOUTH OVER THE ISLANDS ON TUESDAY...BRINGING SCATTERED SHOWERS
TUESDAY MORNING AND INTO THE AFTERNOON. MOST MODELS SUGGEST THAT
THE CONVERGENCE WILL REMAIN TO THE NORTH AND STABLE WILL CONTINUE
THROUGH MIDWEEK. THEREFORE...WILL ONLY AMEND SKY COVERAGE FOR
TUESDAY PERIOD TO MOSTLY CLOUDY SKIES. OTHERWISE...EXPECT ISOLATED
SHOWERS AND GENTLE EAST WINDS DURING THE SHORT TERM.
