Severe T-Storm Watch Likely for the Southeastern Parts of Central Alabama

Here is the text from the latest Mesoscale Discussion from the SPC about the 80% odds of a Severe Thunderstorm Watch being issued for the southeastern parts of Central Alabama:

SUMMARY… A severe/damaging wind threat is expected to continue into the evening with a line of storms moving eastward. Severe Thunderstorm Watch issuance is likely.

DISCUSSION… An organized QLCS will move eastward across parts of southern/central AL through the remainder of the afternoon and into the early evening. A moist and unstable airmass exists downstream of this convection, and to the south of an outflow boundary where additional, non-severe storms have formed. As large-scale ascent and 35-40 kt of mid-level flow associated with an upper trough now over the lower MS Valley continues to overspread AL/GA and the FL Panhandle, the QLCS should maintain its intensity through much of the evening. Given the linear nature of this ongoing convection and steep low-level lapse rates owing to diurnal heating, scattered damaging downdraft winds should be the main threat. The low-level flow is not overly strong, and appears mostly veered to southwesterly per recent surface observations and area VWPs. Accordingly, any tornado threat should remain rather brief/isolated. Severe Thunderstorm Watch issuance will likely be needed to address the damaging wind threat.
