   ...NO SEVERE THUNDERSTORM AREAS FORECAST...

   ...SUMMARY...
   A few strong storms may affect parts of the Southeast including the
   coastal Carolinas on Tuesday, but severe potential appears limited.
   Isolated storms are also expected over Oregon during the afternoon.

   ...Synopsis and Discussion...
   Primarily weak cyclonic flow aloft will persist over
   the eastern CONUS on Tuesday, with a surface ridge from the MO
   Valley into the Northeast. Meanwhile, a front will linger across the
   northern Gulf of Mexico, extending northeastward across the coastal
   Carolinas. While a moist air mass will exist near this boundary,
   several rounds of rain and thunderstorms will mitigate daytime
   destabilization. Low-level winds may be relatively stronger over the
   coastal Carolinas, but any isolated severe threat over land will
   depend on frontal position.

   To the west, a surface trough is forecast to develop over central WA
   and OR during the day, where strong heating will occur. Lapse rates
   aloft will also remain steep with around -10 C at 500 mb. Isolated
   afternoon storms are expected as capping is removed over central and
   eastern OR. Forecast soundings depict deep mixing layers which may
   aid wind gusts. At this time, it appears coverage of storms will be
   low due to limited moisture and little large-scale support for
   ascent.
