A storm system that brought flash floods to parts of Texas Saturday and the Deep South Sunday will affect areas of the Southeast into Monday night.
The storm system will bring a risk of isolated severe weather from Tennessee and northern Alabama to Georgia and the Florida Panhandle Monday evening.
Into Monday, the storm center will track into and through the Tennessee Valley. Much of Mississippi, Alabama and Tennessee is subject to picking up 1 to 3 inches of rain during this time with locally higher amounts.
With rainfall running above normal in this area over the last month, there will be some potential for flash flooding. Urban flooding can occur anywhere due to the intensity of some of the downpours.
Meanwhile, a trailing cold front will cause a few instances of wind damage, hail and perhaps an isolated tornado or two farther south near the Gulf Coast from the Florida Panhandle north through Georgia, part of Alabama and Tennessee.
Through Tuesday, the storm will slowly pull north and the trailing cool front will reach Virginia and the Carolinas. While the threat for excessive rainfall will diminish, the potential for a few strong thunderstorms will still exist over the eastern Carolinas and the Tidewater area of Virginia.
There is a risk of damaging thunderstorms over the eastern Ohio Valley Tuesday.
Showers will push into the Northeast later Tuesday into Tuesday night. However, the threat for heavy rainfall will be diminishing as the storm will begin to weaken and pull away from the rich moisture supply from the Gulf of Mexico.
At midweek, the weakening storm will track through the Great Lakes.
Tuesday into Wednesday will bring a chance for wet weather in the I-95 corridor from Philadelphia to Boston.
The storm's weakening trend is fortunate, since most of the Northeast has seen above-normal rainfall during September and any excessive rain would cause flooding. However, there is the potential for locally severe thunderstorms over part of the Ohio Valley Tuesday.
The storm will exit into Canada on Thursday, but showers may still linger over parts of New England.
Rainfall totals were as high as 10.72 inches in Nacogdoches, Texas, over the weekend, with 5.84 inches in Monroe, La. A large part of the area between the Mississippi River and the Rockies has received at least 2 inches of rainfall through the weekend.
There were a few reports of damaging winds and two tornadoes touched down in Texas as well.
