...NO SEVERE THUNDERSTORM AREAS FORECAST...

Severe storms are not expected today.

An upper impulse will continue to pose a risk of scattered

thunderstorms over parts of NM and south/west TX through the

afternoon, with activity spreading into north-central TX late

tonight.  



Other thunderstorms are possible this afternoon and evening over

south FL in a moist and marginally unstable air mass, along the
