The flooding has already proven deadly in north-central Texas, where several people lost their lives in flooding late Thursday and early Friday.

Abundant moisture from the Gulf of Mexico and a small contribution from former Hurricane Sandra from the eastern Pacific will combine to maintain the risk of torrential rainfall in parts of the southern U.S.

Fortunately, no severe thunderstorms are anticipated through the balance of the Thanksgiving holiday weekend. A cool and stable environment overspread much of the country behind Winter Storm Bella. While rich Gulf of Mexico moisture has returned ahead of this week's storm, the atmosphere's temperature profile is not expected to be unstable enough to support thunderstorms, let alone severe weather.
Sunday
Rainfall Forecast
- No thunderstorms are expected, but locally heavy rain may cause spotty flooding over parts of northeast Texas, southeast Oklahoma and Arkansas.
- During the second half of the day, some heavy rain will shift east across northern Mississippi, far northern Alabama and much of Tennessee.
Locally higher amounts are possible, particularly over Arkansas and Tennessee where training bands of rain may produce rainfall rates in excess of 1 inch per hour for a few hours.
Additionally, some rivers across the Lower Missouri and Middle Mississippi valleys may experience flooding, in combination with upstream snowmelt from Winter Storm Bella and additional rain this weekend.
In some of the aforementioned areas, river flood warnings were issued on Saturday and will continue through Sunday in many cases.

Rainfall Reports
The rain has pushed both Dallas and Fort Worth to their wettest years on record.
Dallas broke its record Thursday, when 2.16 inches of rain at Love Field pushed the annual total to 57.30 inches, breaking the previous record of 55.31 inches in 1981. Another 3.60 inches fell Friday, bringing Love Field to 60.90 inches for 2015.
The Fort Worth area followed suit Friday morning. By the end of Saturday, Dallas-Fort Worth International Airport had received 57.90 inches since the start of 2015, surpassing the standing record of 53.54 inches in 1991.
Major flooding was reported along the Trinity River at Dallas Friday evening into Saturday, as the river was running more than 10 feet above flood stage. However, the river was still well within the flood-protection levees along its course past downtown Dallas.
Several other sites are already within their top 10 wettest years on record based on precipitation through and including Thanksgiving Day. Those include Austin, Texas (second wettest at Camp Mabry); Oklahoma City (fourth wettest); Waco (fifth wettest); Fort Smith, Arkansas (seventh wettest); Corpus Christi, Texas (seventh wettest); and Houston (10th wettest at Bush Intercontinental Airport).
St. Louis, with its 12th-wettest year on record as of Thursday, may reach the top 10 soon as rain continues to fall.
