Overall, a very summer like forecast. A frontal boundary is
expected to be stalled to the north of the area Sunday night into
Monday morning. This means it will be warm and humid as tropical
moisture pools across the Southeast. Highs are forecast in the
upper 80s, which means heat index will quickly rise through the
morning hours to be near or above 90. This is provided that no
showers or thunderstorms are ongoing or occurring to cool things
down - rain chances between 10 am and noon will be 30-40%, and
increase to around 60% by the afternoon hours. Winds will start
light and pick up through the morning hours at 6-10 mph from the
southwest.
