St. Louis, MO – St. Louis residents should prepare for a soggy weekend, as heavy rain and thunderstorms will move through the area Friday night and into Saturday. A Flood Watch remains in effect, with the potential for flash flooding and river flooding across the region, particularly in low-lying areas.
According to the National Weather Service, heavy rain will begin tonight, intensifying into Friday night with the heaviest rainfall expected across southeast Missouri and southwest Illinois.

By Friday afternoon, thunderstorms will develop, with some storms possibly reaching severe levels, bringing large hail as the primary threat.
