The Weather Authority is monitoring the threat of heavy rain for the start of the week. Multiple rounds of rain are forecasted to move through the Tennesee Valley over the next several days. The potential for moderate to heavy rainfall over the next couple of days has resulted in flooding concerns.
A warm frontal boundary is moving in and will stall out over our region Monday night. This will lead to multiple rounds of rain. Some of the rain may be heavy at times and produce localized flash flooding.
Rain showers will pick up in intensity later Monday afternoon and evening. With the continuous flow of tropical moisture and the forcing mechanism of the front, the rain will likely be steady at times. This rain threat will likely continue into early Wednesday.
With ample moisture in place, pockets of moderate to heavy rain are likely to occur. With these bands continuously tracking through the region there will be an enhanced threat of flooding. The best chance for rainfall will be Monday through Tuesday with on-and-off showers continuing through midweek.
Main Threat – Flash Flooding
Rain accumulation Monday through Wednesday will likely range from 1 to 3 inches, with isolated higher amounts possible. The higher rain totals will be associated with the heaviest rand bands that track through the area. The best chance for these heavy bands to impact will be along the Alabama/Tennessee state line and north. Ponding of roadways rises in creeks/streams, and flash floods will all be a risk.
The Weather Prediction Center has the entire area in a ‘Slight Risk’ risk for excessive rainfall. This means the threat of scattered flash flooding is high for the area. A Flash Flood Watch may be issued.
While this rain will be beneficial, the threat of flooding is high. The Weather Authority will be monitoring the forecast closely.
