   Valid 240100Z - 241200Z

   ...NO THUNDERSTORM AREAS FORECAST...

   ...SUMMARY...
   Thunderstorms are not expected today or tonight across the
   contiguous United States

   ...DISCUSSION...
   An upper-level ridge will move eastward across the Ohio and
   Tennessee Valleys tonight as an upper-level ridge moves into the
   central Rockies. At the surface, a large dome of high pressure will
   remain over the Eastern Seaboard and Southeast keeping the airmass
   across the continental United States dry and stable. For this
   reason, no thunderstorms are forecast through tonight.
