A vigorous low pressure system developed and moved across the Tennessee River Valley the night of Monday April 11th. Showers and storms formed ahead of this low, bringing a first round of rain to the region during the day April 11th. The upper level low (in the water vapor satellite image below over southern Missouri) that was driving the surface low (seen over central Tennessee) forced a second wave of precipitation to move slowly through the region Monday night into early Tuesday.
Rainfall totals from Monday morning through Tuesday morning are indicated by the map below. Data are obtained from COCORAHS observers, mesonet and other automated sites, as well as Cooperative Weather observers. Rain continued falling after this map was generated, so amounts over the Bluegrass and Lake Cumberland regions was higher for the storm total.
Because of this rain, many area rivers are at or near flood stage. Check out this website for further information on area rivers. Below are some images sent to us from Marion county of the flooding. If you have additional flood pictures, please e-mail them to the webmaster.
