From Wednesday afternoon through late Saturday night, three to six inches of rain is expected to fall on top of already saturated ground. While isolated flash flooding is not out of the question Wednesday night or this weekend, area rivers and streams are going to be on the rise. Those who experienced flood during the past week need to pay special attention to rainfall accumulations as flood is expected to return to those locations.
Monitor weather forecasts and be alert for potential flood warnings.
A slow moving frontal system is forecast to push into Middle Tennessee on Wednesday and linger across the area into Thursday. This system will provide some parts of Middle Tennessee with moderate to heavy rainfall. A second system will move in over the weekend and bring another round of moderate to heavy rainfall to the same areas.
Right now, it looks like northwestern Middle Tennessee will receive the most rainfall over the next five days, with rain totals between Wednesday morning and Sunday morning expected to average between three to five inches, with locally higher amounts above six inches possible. Most of the heaviest rainfall isforecast north and west of a line from Lobelville to Portland, including areas around Clarksville, Springfield and Dickson. Other parts of the Mid State are forecast to receive between one and a half and three inches over the next five days.
The periods of heaviest rainfall are expected to be Wednesday afternoon and Wednesday night, and again Saturday afternoon and Saturday night.
Since the grounds in Middle Tennessee are still very wet from previous rains, any additional heavy rainfall could lead to localized flash flooding as well as river and stream flooding.
Stay tuned to the latest forecast and listen for any watches or warnings that might be prompted by the heavy rainfall over the next five days.
