   ...NO THUNDERSTORM AREAS FORECAST...

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

   ...Synopsis...
   Upper pattern is forecast to remain progressive on Tuesday, with the
   deep upper trough initially along the Eastern Seaboard moving
   quickly eastward as expansive upper ridging moves from central
   Plains across much of the eastern CONUS. At the same time, upper
   troughing will deepen across the western CONUS, aided by a pair of
   phased shortwave troughs, one moving across the Pacific Northwest
   and northern Rockies and the other moving across the southern
   CA/Baja Peninsula into southern AZ and far northwest Mexico. 

   At the surface, a large area of high pressure will drift eastward
   across the eastern CONUS, keeping conditions stable. Deepening
   surface pressure is anticipated across the Plains ahead of the
   approaching upper trough, with the resulting pressure gradient
   supporting moderate low-level southerly flow. Some moisture return
   is anticipated across TX as a result, but much of the low-level
   moisture was displaced well south by a previous cold front, and
   upper 50s dewpoints will likely remain confined to areas south of
   I-10.

   Stable conditions are expected across the majority of western CONUS
   as well. The only exception is across eastern AZ/western NM where
   strong ascent and cold temperatures aloft could result in a few
   updrafts capable of producing lightning. However, coverage is
   forecast to remain below 10%.
