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.

Brandon Chambers April 29, 20144:44 pm

Strong storm moving NE at 40mph through Eastern Giles and Northern Lincoln Counties in Tennessee. Small hail and frequent lightning possible.

Brandon Chambers April 29, 20145:06 pm

5:04PM : Scattered showers and isolated storms continue across North Alabama, mainly west of I-65, and Southern Middle Tennessee. No active severe thunderstorm warnings at the moment, but occasional heavy downpours, small hail, and gusty winds will still be 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.

A small shower developing over Huntsville as seen from our high vantage point of the Monte Sano camera… This storm could grow in strength, but is well below severe limits at the moment.

Brandon Chambers April 29, 20145:46 pm

Another look at radar at 5:45PM. Still nothing officially severe here in the Tennessee Valley. Mainly just heavy rain and occasional lightning, especially west of I-65. All storms are lifting northeast.

Jason Simpson April 29, 20146:06 pm

Three storms showing signs of rotation right now; none of them quite strong enough to produce a tornado just yet.

Brandon Chambers April 29, 20147:12 pm

Very strong storms over Lincoln Co, TN… doesn’t have any  warnings with it at the moment, but torrential rain, lightning, gusty winds, and hail are all possible. It’s moving north at close to 50mph, so it should let up soon in Southern Lincoln Co, but more are following behind it.

Report from Kerry Sides in Limestone County: Multiple trees down on Huntsville Brownsfery Rd East of Four Way Stop on Moresville Rd.

Very intense storm right over the Quad Cities in the Shoals.  No warning with it right now, but stay away from windows until it passes.

Brandon Chambers April 29, 20147:56 pm

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.

Brandon Chambers April 29, 20147:56 pm

The tornado watch has been CANCELLED for all of North Alabama and Southern Tennessee.

Brandon Chambers April 29, 20148:40 pm

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.

Brandon Chambers April 29, 20148:53 pm

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.
