...NO THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Thunderstorms are not expected Wednesday.

...Synopsis...

A series of upper shortwave troughs within broader northwesterly
flow aloft will move across the Southeast and from the Rockies into
the Plains on Wednesday. Lee cyclogenesis is expected to develop
over the central High Plains in response to the ejecting upper
shortwave trough, with the low eventually migrating toward OK.
Southerly flow will increase across the southern Plains in response,
but surface high pressure over TX into the Southeast will prevent
modified Gulf moisture from returning northward. As a result, a
cold, dry, and stable airmass will remain over much of the CONUS,
precluding thunderstorm activity.
