...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF
UPPER TEXAS AND SOUTHWEST LOUISIANA COASTS...
...SUMMARY...
A storm with isolated severe hail will be possible tonight along the
upper Texas and southwest Louisiana coasts.
...Upper Texas and Southwest Louisiana Coasts...
Water vapor imagery shows a trough over the Desert Southwest with
west-southwesterly flow located across much of the southern U.S. At
the surface, a moist airmass is located over much of the western
Gulf. The northern edge of the moist airmass impinges the middle
Texas Coast, and model forecasts suggest that the airmass will
gradually shift northeastward along the upper Texas into far
southwest Louisiana. Although warm-advection-related thunderstorms
will be mostly concentrated offshore, an isolated strong storm with
hail potential could develop in far southeast Texas or far southwest
Louisiana from late evening into the overnight period.
