SPC Removes Slight Risk from North Alabama

Posted on: 3:35 pm, April 16, 2013, by

Some heavier thunderstorms are still possible, but due to the lack of storms so far and the fact that this upper-air disturbance will be moving out of the area soon, the risk of severe weather is diminishing. In fact, the Storm Prediction Center has dropped the SLIGHT RISK for the Tennessee Valley.

Radar images this afternoon have made the absence of storms abundantly clear! The yellow circles here indicate areas of growing thunderstorm activity in Mississippi and Tennessee as of 3:25 PM:

There still remains a threat of a few stronger storms in northern Middle Tennessee this afternoon and evening:

We seemingly have all we need for some heavy summer-like storms, but they just aren’t developing. The latest sounding from UAHuntsville’s MPR site shows CAPE (instability) approaching 2,000 J/kg in Huntsville. That’s more than enough for some storms.

So, a few showers and storms are possible for the rest of the afternoon, but don’t cancel outdoor sports practices, games, etc. These showers will pass through quickly.

Looking Ahead…

The storm system arriving Thursday night/Friday morning is looking a little more concerning than it did just about 24 hours ago. We still expect a slow weakening trend in the storms as they move east through Alabama and Tennessee Friday morning, but that does not clear us from a severe weather threat completely. It’s something we’ll keep tabs on for the rest of the week, and as always, we’ll keep you updated. More on this threat is detailed at WHNT.com/Weather.
