   ...NO SEVERE THUNDERSTORM AREAS FORECAST...

   ...SUMMARY...
   Severe storms are not expected across the U.S. Wednesday.

   ...Synopsis...
   A positively tilted mid-level trough will continue advancing
   southeast across the central and eastern U.S. Wednesday/Day 2, while
   a second system -- a large low off the Pacific Northwest coast --
   drifts eastward and begins to nose inland.  Finally, a short-wave
   trough -- embedded within cyclonic flow around a large Hudson Bay
   vortex -- is forecast to progress east-southeast across the northern
   Plains and upper Great Lakes through the end of the period.

   At the surface, a clipper-type front is forecast shift across the
   north-central U.S. and Great Lakes in conjunction with the
   aforementioned upper feature.  Meanwhile, a front lingering near the
   Gulf Coast will continue sliding slowly southward into the Gulf of
   Mexico.  Finally, a low -- barotropically aligned beneath the upper
   vortex -- will linger off the Pacific Northwest coast.

   Widespread showers are expected across parts of the western U.S. as
   the eastern Pacific storm system approaches.  A few lightning
   strikes may also occur, mainly late in the period over the higher
   terrain of the Pacific Northwest.  Meanwhile, showers are also
   forecast near and to the cool side of the southern U.S. surface
   front.  A thunderstorm or two may also occur within this zone --
   both across the southern New Mexico/West Texas vicinity in
   conjunction with an advancing upper wave, and over the southeast
   U.S. where some elevated CAPE may linger.  In both areas, convection
   is forecast to remain weak/disorganized.
