...NO SEVERE THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Severe thunderstorms are not expected through tonight.

Broad cyclonic mid-level flow prevails across the northern U.S. at
00Z with an embedded shortwave trough approaching the northern
Plains and a downstream trough lifting northeast across northern New
England. Surface analysis depicts a nearly stationary surface front
extending from western/northern NY southwest through the mid
Mississippi Valley and then across central TX. Thunderstorms were
scattered in the vicinity of the front from western KY south into
northeast TX, where upper 60s to lower 70s dew points were
contributing to weak/moderate surface-based instability. Scattered
storms are expected to persist along the front through the overnight
hours, however generally weak instability should limit overall
intensity.

Thunderstorms have diminished across the FL peninsula this evening,
however widely scattered thunderstorms will remain possible
overnight in the presence of a mid-level trough and weak/moderate
instability.
