Flood threat via Weather Prediction Center
MADISON (WKOW) - After a dry weekend, rain moves back in for Monday and could be heavy at times.
An upper level, low pressure system is developing over the Central Plains and will pass south of our area to start the work week. Thundershowers will develop by late morning with periods of wet weather expected the rest of the day and overnight. By Tuesday morning, most of southern Wisconsin will have picked up an additional 1-2 inches with hot spots getting up to 2-4 inches. Areas that saw flooding late last week may get more of the same.
Because of this, the National Weather Service has issued a Flash Flood Watch for much of Southern Wisconsin, effective Monday afternoon through Tuesday morning. If you see water-covered roads, please find an alternate route There is also a low chance of a brief, weak, isolated tornado developing Monday afternoon. Computer models show some rotation in the low-levels of the atmosphere. However, the largest severe threat will stay well south of our area.
