.DISCUSSION...
Warm and humid environment persists through early Friday that will
create chances, at times higher probabilities than others, for
showers and thunderstorms that could create gusty wind and heavy
downpours.
A frontal passage with upper shortwave movement Friday portends a
subtle cooling and more notable drying trend that results in lower
humidity and seasonable temperature by Saturday.
