...NO SEVERE THUNDERSTORM AREAS FORECAST...

...SUMMARY...
No severe threat is forecast over the continental U.S. today or
tonight.

...DISCUSSION...
An upper-level trough will move from the Northeast offshore into the
western Atlantic today. At mid-levels, westerly flow will prevail
over much of the central U.S., as a trough amplifies in the northern
Rockies. Isolated to scattered thunderstorms will be possible ahead
of the trough this afternoon. As the trough moves into the Great
Plains tonight, thunderstorms will be possible near the edge of a
low-level jet in parts of the upper Mississippi Valley. Scattered
storms may also develop across the Florida Peninsula today. No
severe threat is forecast today or tonight across the U.S.
