....NO SEVERE THUNDERSTORM AREAS FORECAST...

....SUMMARY...
Severe thunderstorms are not forecast across the United States
through tonight.

....Synopsis...
A midlevel low over northwest OK this morning will eject slowly
east-northeastward toward MO by tonight, as an upstream wave digs
south-southeastward from southern AB/SK toward SD/NE.  A band of
rain with embedded convection persists from central TX into central
OK, in association with the midlevel low and a reinforcing frontal
surge across OK/TX.  The band of ascent/rain will spread eastward
and southeastward through tonight, with weak buoyancy aloft
supporting a continued threat for isolated lightning flashes through
tonight (primarily from north TX to southeast TX).  Otherwise, some
convection and isolated lightning flashes may also occur across
south FL/Keys in the persistent easterly flow regime along a
residual front.
