Region braces for severe weekend weather outbreak

Editor’s note: This story will be updated as conditions warrant.

TENNESSEE: While no watches and warnings have been issued yet, periods of heavy rainfall are expected across much of Middle Tennessee early Saturday morning through Saturday evening and severe weather including severe thunderstorms and the possibility of tornadoes will move from west to east throughout all of Tennessee tonight and Saturday. As the storms pass through, the summerlike temperatures of the past several days will plummet by 15-50 degrees depending on where you live.

A cold front will drop into Middle Tennessee Saturday night and move into the east early Sunday morning. Locally heavy rainfall is expected to come in the form of possibly a few waves. The period when our flood potential will be highest will be Saturday evening. This same system is triggering blizzard conditions and the possibility of an ice storm across the northern tier of states into New England.

Storm total rainfall for the weekend is forecast to range between two and four inches, with the highest storm totals expected south of I-40, closer to the Alabama state line.

Grounds will become increasingly saturated, possibly leading to localized flooding problems caused by increased runoff Saturday night. Some river flooding is also possible as area rivers, creeks and streams rise heading into Sunday and later.Here’s what to expect.:

Friday – Friday Night

  • Severe thunderstorms are expected across a wide area from the afternoon through the evening, from eastern Texas, Louisiana and Mississippi northward to eastern Oklahoma, Arkansas, western Tennessee, Missouri, eastern Kansas, eastern Nebraska, Iowa and far western portions of Illinois and Kentucky.
  • Damaging winds, large hail and tornadoes, including a few strong tornadoes and a few thunderstorms capable of very large hail stones. Heavy rain could contribute to local flash flooding.
  • Cities affected: Houston | Little Rock | Memphis | Shreveport | Kansas City | Des Moines

Saturday – Saturday Night

  • Severe thunderstorms will likely continue in the South, possibly as a squall line. The greatest probability of severe weather appears to be in southeastern Louisiana, southern and eastern Mississippi, Alabama and the Florida Panhandle, but at least scattered severe storms are possible as far north as the Ohio Valley.
  • Damaging winds are likely the biggest concern, but a few tornadoes cannot be ruled out. Localized flash flooding will also be possible.
  • Cities affected: Birmingham | Jackson, Mississippi | New Orleans | Nashville
