More heavy rain is on the way for areas of southern Minnesota that have already been hit with 1-2 inches, and in some areas 3-4 inches in the last 24 hours. 

According to the National Weather Service, multiple rounds of strong storms capable of producing torrential rainfall are expected Wednesday through Thursday, and as of Tuesday evening the Twin Cities is parked in the middle of the bullseye. 

"Atmospheric conditions are coming together for allowing several rounds of very heavy rainfall from Wednesday night, through Thursday night," The NWS Twin Cities forecast discussion reads. 

"The only concern is where the focus of the heaviest rainfall will occur, especially once the main bands of convection develop along and north of a warm front Wednesday night, and Thursday."

Current thinking has the main band of heavy rain over the Twin Cities, although exact placement could shift further north or south by the time it actually develops. 

The Weather Prediction Center (SPC), which handles excessive rainfall outlooks, currently has all of southern Minnesota in a slight risk for excessive amounts of rain on Wednesday and Wednesday night, and confidence in exact locations could prompt that threat to be upgraded to a moderate risk. 

Some computer models are suggesting five inches of rain are possible in southern Minnesota, the WPC says. 

Here's a look at a simulated future radar from 4 a.m. Wednesday through 11 p.m. Thursday. Do note that this is projecting well out in advance of what will happen, but it at the very least paints a good picture of the waves of heavy rain and storms possible over the next 48 hours.

Meanwhile, more extreme rainfall totals are possible Thursday in addition to the threat of storms reaching severe levels. Large hail and damaging winds are the main threats for Thursday afternoon and evening before the storms weaken after dark, according to the Storm Prediction Center.
