According to the National Weather Service, showers and thunderstorms are likely after 2 p.m. Wednesday, with rainfall totals reaching a half inch or more in some spots. Flood-prone areas in Montgomery County, especially around US-460 and local neighborhoods, should prepare for pooling water and brief road closures.
