...NO THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Thunderstorms remain unlikely through tonight.

...Discussion...
High pressure will remain situated over the majority of the CONUS
through tonight, with any appreciable low-level moisture well
offshore into the western Gulf. While a shortwave trough will move
across AZ and NM tonight, loss of heating should minimize lapse
rates and instability there.
