Areas affected...Deep south Texas

Concerning...Severe potential...Watch unlikely

Valid 170740Z - 171015Z

Probability of Watch Issuance...20 percent

SUMMARY...A corridor of severe wind and small hail is possible
across parts of deep south Texas, mainly along and south of the
latitude of Corpus Christi. A watch is not expected.

DISCUSSION...A well-organized bow echo has crossed the Rio Grande
near Laredo, and will continue in an east to southeastward direction
this morning. This feature appears to be driven mainly on
instability and the presence of an MCV, as flow aloft and shear
remain relatively weak. However, sufficient moisture and instability
may support a continued localized severe wind threat with this
system as it traverses southern Texas and eventually moves offshore.
