..no severe thunderstorm areas forecast... 


... 
only isolated thunderstorms are expected on Wednesday across the 
western/central Gulf Coast, and severe weather is not forecast. 


... 
Downstream of a broad trough ejecting east/northeast across the 
Southern Plains on Wednesday, a warm-advection regime will establish 
from eastern Texas to the lower Mississippi Valley. This pattern 
should support widespread rainfall across much of the region, but 
very limited buoyancy will likely preclude thunderstorms in most 
locations. The only exception is expected to exist along the 
middle/Upper Texas and Louisiana coasts, where sufficient inland 
destabilization should favor isolated thunderstorm activity. A lack 
of more substantive buoyancy, combined with the unorganized nature 
of the ejecting trough, is expected to preclude severe weather, 
though. 


Elsewhere, a couple of lightning strikes may occur over western 
Colorado, but the eastward departure of the primary trough should 
limit cooling aloft, likely keeping any lightning too isolated for a 
general thunder area. 


..maximum risk by hazard... 
Tornado: <2% - none 
wind: <5% - none 
hail: <5% - none
