1 pm Weather Check — Atmosphere Continues to Destabilize Across the Area

The atmosphere is really starting to destabilize across the western half of the state as instability values are now ranging from 1,000-1,500 J/kg and continues to increase as you move into Mississippi. Dewpoints are already in the lower to mid 60s west of I-65, and are expected to slowly rise as the moisture will continue to build through the afternoon and early evening. The Significant Tornado Parameter values for now are mostly 1.0 and above in those locations, with 2.0-3.0 showing up in Mississippi.

While we have some thunderstorm activity down over the southwestern parts of Central Alabama, at this point, this activity is well below severe limits. We also notice some scattered shower development in the northwestern parts of the area. We’ll have to watch all of this activity and new development as this will be moving through unstable air.

Just a heads-up, Demopolis NOAA Weather Radio is currently having some transmission issues. Please use 162.450 MHZ and 162.400 MHZ as backup until the situation with the Demopolis is corrected.

Much of Central Alabama and nearly all the Tennessee Valley continue in an Enhanced Risk for severe storms through the remainder of today, while the rest of the Tennessee Valley and much of the rest of Central Alabama remain in a Slight Risk. The southeast corner of Central Alabama is in a Marginal Risk for severe storms.

Here is a chart to inform you about the Severe Thunderstorm Outlook categories and the definitions of severe storms. In the Enhanced Risk locations, there is the potential of stronger tornadoes of EF2 or greater. Damaging winds up to 70 mph will be possible across all the state, along with large hail up to 1.5 inches in diameter.

Stay weather aware and be ready to act if your location goes under a warning.
