Southern Minnesota is bracing for heavy rains and potential flooding tonight.

The National Weather Services issued flash flood watches through 10 a.m. Wednesday for much of southern Minnesota, including Mower and Freeborn counties.

Heavy rainfall is expected to move through much of the region tonight and Wednesday morning, bringing widespread rainfall amounts of 1 to 3 inches with 1 to 2 inches per hour possible in heavier spots, according to the weather service.

The weather service also warned of poor visibility during the heaviest rains, which will make for difficult driving. Torrential downpours could result in washouts or street flooding in some towns, according to the weather service.

A few thunderstorms could be severe. Along with the heavy rains, damaging winds and large hail are also possible.

After the strong low pressure system moves through the area, temperatures are expected to drop across the region.

Albert Lea will drop from a high of 78 today to highs of 65 on Wednesday, 56 on Thursday, 55 on Friday and 59 on Saturday.
