...NO SEVERE THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Thunderstorms are forecast across portions of Louisiana and
immediate surrounding areas today. Additional isolated thunderstorms
may occur in portions of Oregon/Washington. No severe weather is
expected.

...TX/LA...
A prominent shortwave trough is tracking eastward across TX today,
providing lift and destabilization to parts of southeast TX and LA.
Scattered thunderstorms have been occurring in this region through
the morning, but should slowly shift offshore by later this
afternoon as the upper system passes. While small hail could occur
with the strongest onshore storms, no severe weather is anticipated.

...WA/OR...
Recent water vapor loop shows a strong shortwave trough approaching
the Pacific Northwest coast. As this system approaches,
strengthening onshore flow and cold temperatures aloft will increase
the risk of at least isolated thunderstorms - mainly this evening.
