   ...NO THUNDERSTORM AREAS FORECAST...

   ...SUMMARY...
   Thunderstorms are not expected on Friday.

   ...Synopsis...
   A pair of phased shortwave troughs are forecast to progress through
   the large-scale troughing expected to be in place across the eastern
   CONUS, moving off the Mid-Atlantic coast by Friday afternoon.
   Mid-level flow will strengthen in the wake of these waves,
   coincident with another shortwave trough dropping from the northern
   Plains into the Mid MS Valley. Expansive surface ridging will cover
   much of the central and eastern CONUS, with the associated dry and
   stable conditions dominating the sensible weather and precluding
   thunderstorm development.

   Father west, ridging will continue gradually shifting eastward,
   ahead of a progressive shortwave trough forecast to move into the
   Pacific Northwest. By early Saturday, the upper ridging is expected
   to extend across the entire High Plains and into Alberta and
   Saskatchewan, with the shortwave trough extending from northwest
   WA/southwest British Columbia through the western Great Basin. 

   Frontal band associated with the progressive shortwave will likely
   move onshore early Friday. Some deeper cells are possible within
   this band, but these cells will still be too shallow for lightning
   production. Another period of deeper convection is possible as the
   upper trough and cold mid-level temperatures approach the coast
   Friday afternoon. A few low-topped thunderstorms are possible
   offshore, with a low-probability flash or two possible over
   immediate coastal portions of WA and OR as well.
