One-two punch Tuesday, Wednesday
Expect the worst of the rain Tuesday night into Wednesday; and Wednesday during the day and into the evening will be prime time for thunderstorms and possible tornado weather, Barnes said.
"We're looking at probably starting out with light rain today [Monday], for the metro area, about 2 p.m.," he said. Going into Tuesday, the rain will be "moderate" with periods of heavy rain. "There are some concerns for flooding mid-week," Barnes said.
The heaviest rain will likely fall Tuesday night, through pretty much all day Wednesday, with Wednesday afternoon seeing a threat for thunderstorms, Barnes said. Some of those thunderstorms may be severe; the area could see damaging wind gusts both Tuesday and Wednesday.
"There is a possibility" for tornado weather on Wednesday, he said. "The best chances for any tornado formation would be Wednesday afternoon going into Wednesday night; depends on how [the thunderstorms] swarm up and get organized."
