What To Expect: Severe Storms Possible Saturday Evening

The Storm Prediction Center outlines a ‘marginal’ risk of severe storms for mainly Saturday evening in North Alabama and Southern Tennessee; this risk indicates a few storms could produce damaging winds or large hail.

What to expect from weekend storms: Rain and a few thunderstorms are moving through north Alabama this evening, but the atmosphere is relatively stable enough to suppress a widespread severe weather event. With that said, a storm may be able to be strong to severe enough to produce a damaging wind gust through as late as 1 AM Sunday.

The severe weather risk if mainly west of Huntsville with this band of storms, and even that risk is on the low-end of the spectrum: ‘marginal.’ That literally means ‘isolated severe thunderstorms are possible, which are limited in duration and/or coverage and/or intensity’. The Storm Prediction Center’s outlook shows a 5% chance of a severe wind gust (58 MPH+), severe hail (quarter-sized or larger), and only a 2% chance of a tornado. Those numbers are very low; however, anytime there’s a threat of any kind, it’s beneficial to be aware of it.

The kind of atmosphere we have in place Saturday evening does not look especially volatile; in other words, there’s not a lot of fuel for storms. We expect the main issue to be strong winds over 40 MPH with some isolated storms within the band capable of producing a 60 MPH+ gust.

Go about your plans as you normally would, but be aware that a line of heavy storms will move through Saturday evening. When those storms are nearby, you can track them and see how intense they are with WHNT.com’s Interactive Radar or swipe over to the radar feature on Live Alert 19!

Total rainfall Saturday night and Sunday morning looks pretty meager: only about 0.20” to 0.50” on average. A few spots could end up with a little more than that, though!
