....NO THUNDERSTORM AREAS FORECAST...

....SUMMARY...
Thunderstorms are not expected through tonight.

....Synopsis/Discussion...
A mid/upper-level trough will continue eastward from the Eastern
Seaboard into the western Atlantic Ocean today, while an amplified
upper ridge persists over the West. On the backside of the eastern
CONUS trough, large-scale subsidence amid a cold/dry post-frontal
air mass will limit thunderstorm potential east of the Rockies.
Similarly, low theta-e air accompanying an expansive continental
polar surface high over the Intermountain West will preclude
thunderstorms west of the Rockies.

While a robust shortwave trough with cold temperatures aloft will
track southeastward across the Midwest tonight, limited elevated
instability ahead of a related cold front and expected band of
low-topped convection should also limit lightning potential.
