Tornado Watch canceled for Tennessee Valley, rain and wind still possible

Heavy rain and severe storms moving across North Alabama and Tennessee through the evening could pack a punch with high winds, frequent lightning, tornadoes and flash flooding.  The risk of severe storms is highest west of the Huntsville area in The Shoals and northern Mississippi; however, the threat is not zero to the east!

The Storm Prediction Center’s outlook still tells a tale of potential with some uncertainty.  In other words, there’s an ‘if’ in the forecast today.  If the storms take advantage of the environment, then they could be especially severe within that orange ‘enhanced’ risk area:

‘A couple of strong tornadoes will be possible later this afternoon into this evening when semi-discrete supercells are most probable within the warm sector, and prior to low-level shear weakening substantially by late this evening as the synoptic wave exits to the northeast.’

What we expect on Saturday: Storms entering the region this afternoon will be weakening and moving out around midnight; however, while they exist, some isolated instances of very strong, damaging winds and tornadoes are possible.

When? – (now to 12 AM Sunday) – Showers are possible all day Saturday; however, there appear to be two primary waves of wet/stormy weather.

Scattered thunderstorms ahead of the main wave may help to reduce the instability for some, but we think there will be enough fuel and wind shear to overcome that through the evening.  These two snapshots from our Futurecast tell the story well: strong wind shear and the potential for rotating storms:

Where? – All of North Alabama and Southern Tennessee.  Storms may be strongest over the western side of the state of Alabama and Tennessee; however, they will not dissipate before reaching the Georgia border.  Be alert!  Go about your business Saturday, but know your surroundings and know how to quick information when you need it.

It’s important that you have multiple ways to get warnings including our Live Alert 19 app.
