8:22 PM – Scattered thunderstorms will continue through the evening, but the larger-scale severe weather threat is over for the Tennessee Valley. An isolated storm may briefly turn severe with some gusty winds or hail along with frequent lightning and heavy rain, but this does not look ANYTHING like the storms last night.
A couple of heavy showers have formed in Southern Tennessee and are moving northeast. We’re also keeping an eye on stronger storms moving toward NW Alabama from Mississippi. No severe thunderstorm warnings are in effect.
A tornado watch remains in effect until 10PM.
Strong storm moving NE at 40mph through Eastern Giles and Northern Lincoln Counties in Tennessee. Small hail and frequent lightning possible.
HRRR short-range model guidance showing a slight enhancement in the Significant Tornado Parameter (an index we use to monitor the likelihood of severe weather/tornadoes) in NE Alabama, West-Central Alabama, and near the Gulf Coast at 8 PM. Tornado Watch in effect means any of those storms could grow severe quickly; they will not be as intense as Monday’s storms, but they will still pose some element of danger.
Three storms showing signs of rotation right now; none of them quite strong enough to produce a tornado just yet.
From the National Weather Service at the request of the Limestone County EMA:
DUE TO THE EXTENSIVE SEVERE WEATHER THAT IMPACTED LIMESTONE COUNTY LAST EVENING...LIMESTONE COUNTY EMERGENCY MANAGEMENT REQUESTS THAT ALL NON ESSENTIAL PERSONS STAY OFF THE ROADS THROUGH 10 PM CDT. RECOVERY EFFORTS CONTINUE AND TEAMS NEED ALL AVAILABLE ROADWAYS TO ACCESS DAMAGE AREAS THROUGHOUT THE COUNTY. IN ADDITION TO THE STORM DAMAGE DEBRIS...DOWNED POWER LINES CONTINUE TO POSE A DANGEROUS HAZARD TO MOTORISTS AND PEDESTRIANS.
Picture of what looks like a ragged wall cloud near Town Creek from Melissa Cannon:
Some of the heavier storms are producing small hail & gusty winds; Severe Thunderstorm Warning still in effect for Limestone and Madison Counties.
Severe T’storm warning continues for Northern Limestone and Northern Madison Counties until 7:15pm… strong winds over 60mph are the primary threat.
Moving NE at 50mph
The severe thunderstorm warning for Limestone and Madison Counties has been cancelled.
No other severe warnings are in effect as of 7:00pm. Tornado watch continues until 10PM
Report from Kerry Sides in Limestone County: Multiple trees down on Huntsville Brownsfery Rd East of Four Way Stop on Moresville Rd.
Photo In Tuscumbia by Matthew Keenum. This storm is showing some weak rotation on radar and producing hail in Muscle Shoals. It’s moving east of Downtown Florence headed up toward NE Lauderdale County.
A line of storms has formed from N. Lawrence County through Eastern Franklin County, south into Eastern Marion County. The line is moving very slowly so flooding may be an issue.
The tornado watch has been CANCELLED for all of North Alabama and Southern Tennessee.
A few heavy but non-severe storms are moving into NW Alabama. There’s very little lightning, and the risk of severe storm development is very, very small.
Radar Update 8:52 PM: heavy, loud storms increasing in strength over Franklin & Colbert Counties. Lightning, small hail the main threats with this cluster moving NE toward Russellville, Littleville, and Colbert Heights.
Severe Thunderstorm Warning for the area boxed in yellow in The Shoals – hail, gusty winds likely with this storm moving into the west side of Florence (9:05 PM radar image)
