...NO SEVERE THUNDERSTORM AREAS FORECAST...
...SUMMARY...
The risk for thunderstorms appears negligible across much of the
nation tonight.
...01Z Update...
Drying and stabilizing trends are now well underway across
southeastern Florida coastal areas and the Keys, where
lower/mid-tropospheric wind fields have veered to northwesterly.
Some lightning was noted earlier in a convective band within
west-southwesterly low-level flow emanating from Lake Ontario, where
trajectories across the relatively warm lake waters are maximized.
Additional convection occasionally becoming capable of producing
lightning appears possible to the east of Lake Ontario through at
least 05-06Z, before this potential becomes more negligible as mean
lower/mid-tropospheric winds begin to veer to a more
westerly/northwesterly component.
