...NO SEVERE THUNDERSTORM AREAS FORECAST...
...SUMMARY...
Severe thunderstorms are not expected today or tonight.
Dry and stable conditions will prevail over most of the CONUS today,
with a few small exceptions. A strong cold front sagging southward
across TX might result in isolated afternoon thunderstorms over
south TX. Widely scattered showers and thunderstorms could affect
south FL this afternoon as the same front weakens and approaches the
area. And finally, a few lightning strikes could occur inland
across western WA late tonight as a strong shortwave trough
approaches. No severe storms are anticipated in any of these areas.
