...Heavy Rainfall Forecast Thursday Night through Friday Evening...

After some light rains wet the ground early this week, a heavier
bout of rainfall will be moving in toward the end of the week.
Forecast average storm total amounts will be in the 2 to 3 inch
range by the time the rain chances end late Friday night.

This amount of rainfall falling on top of wetted grounds may lead to
flooding issues, especially where thunderstorms might locally
enhance those amounts to greater than 3 inches. WPC has the entire
region in a slight risk for developing flooding issues.

Stay tuned to updates and be ready for potential Watches and
Warnings for this late week rain event.
