Day 1 Convective Outlook  

NWS Storm Prediction Center Norman OK

1244 AM CDT Mon Apr 29 2024



Valid 291200Z - 301200Z



...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS FROM PARTS OF

SOUTH TEXAS INTO THE LOWER MISSISSIPPI VALLEY...



...SUMMARY...

Marginally severe wind gusts and hail will be possible today from

parts of south Texas northeastward into the lower Mississippi

Valley.



...South Texas/Lower Mississippi Valley...

At the start of the period, a linear MCS will be ongoing from the

southeast Texas Coast northeastward into the lower Mississippi

Valley. The strongest part of the MCS is expected to be in southern

Louisiana during the first three hours of the period, from 12Z to

15Z. The wind-damage threat is expected to remain isolated as it

moves southeastward across the Louisiana Coast this morning. A

marginal wind-damage threat is also expected further northeast into

south-central Mississippi from this morning into early afternoon.

However, instability should remain very weak, limiting the severe

threat potential.



Further southwest into south Texas, a moist and unstable airmass

will be in place from the Rio Grande River eastward to the middle

Texas Coast. Along the northern edge of this moist airmass, isolated

storms may develop this afternoon. Moderate deep-layer shear should

be enough to support a marginal severe threat. However, any threat

should be very isolated.
