An upper level disturbance will move across the area Tuesday bringing some clouds and a few showers. Rain will not be significant and will not aggravate flooding over Northeast Florida and Southeast Georgia. Temperatures will only top out in the 70s and will dip at times into the 60s during any shower activity. Tuesday night will be another cool night before rapid warming begins Wednesday culminating with highs close to 90 degrees Thursday and Friday. The next chance for much in the way of significant rain will be Sunday.
