.DAYS TWO THROUGH SEVEN...SATURDAY THROUGH THURSDAY

There is a chance for a decaying line of thunderstorms to move

Hot and humid conditions are anticipated Saturday with peak heat

Saturday evening through Monday, we will see persistent chances
for showers and thunderstorms. There is an increasing threat for
periods of very heavy rainfall, mainly from Saturday evening
through Sunday night, which may lead to some areas of flash
flooding. A very humid air mass may result in hourly rainfall
rates between 1 to 3 inches from the strongest storms. This
heavy rain may exacerbate any ongoing river flooding or lead to
new flooding on area rivers. A Flood Watch remains in effect from
Saturday afternoon through Monday afternoon.

Also for Saturday into Saturday night, the Storm Prediction
Center has a Slight Risk for severe storms for much of the area,
with the primary threat damaging winds.
