   ...NO THUNDERSTORM AREAS FORECAST...

   ...SUMMARY...
   Severe thunderstorms are not expected on Tuesday.

   ...Synopsis...

   A mid/upper shortwave trough over the Upper Midwest will shift
   east/northeast to New England on Tuesday. Meanwhile, an upper trough
   will develop eastward over the western U.S. and deepen as it
   approaches the Rockies and adjacent High Plains late in the period.
   Surface high pressure over the Southeast will continue to limit
   boundary-layer moisture across much of the U.S. east of the Rockies.
   However, lee surface troughing will develop late in the period in
   response to the ejecting western trough. This will result in
   increasing southerly low-level flow, allowing for modest northward
   transport of Gulf moisture over parts of the southern Plains.
   However, thunderstorm potential will remain low given poor
   instability and weak forcing, though some showers are possible in
   developing warm advection across parts of eastern TX/OK/KS Tuesday
   night/early Wednesday.
