Valid 221300Z - 231200Z

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

....SUMMARY...
Severe thunderstorms are not expected through tonight.

....Discussion...
Thunderstorm potential will remain quite limited across the CONUS
through tonight. Two exceptions will be in the extreme northwest and
southeast portion of the Lower 48.

In south FL, the presence of low 70s surface dew points combined
with modest boundary-layer heating may yield isolated thunderstorms
this afternoon. Pronounced weaknesses in lapse rates, shear, and
ascent will preclude a greater convective threat.

In northwest OR and southwest WA, a vigorous shortwave trough should
impinge on the coast midday and progress across the Northwest
through tonight. A sliver of surface-based instability may develop
in its immediate wake, with a small chance of a couple thunderstorms
between 20-00Z.
